**GENERAL**

We are a leading international mining company with headquarters in Phoenix, Arizona. We operate large, long-lived, geographically diverse assets with significant proven and probable mineral reserves of copper, gold and molybdenum. We are one of the world's largest publicly traded copper producers. Our portfolio of assets includes the Grasberg minerals district in Indonesia, one of the world's largest copper and gold deposits; and significant mining operations in North America and South America, including the large-scale Morenci minerals district in Arizona and the Cerro Verde operation in Peru.

Our results for the year 2022 reflect strong production performance, with higher consolidated copper and gold production and sales volumes when compared to 2021 and 2020. We achieved an 11% increase in copper sales volumes and a 34% increase in gold sales volumes in 2022, compared to 2021. Despite economic uncertainty, we continued to generate positive operating income and operating cash flows. We believe the actions we have taken in recent years to build a solid balance sheet, successfully expand low-cost operations, and maintain flexible organic growth options while maintaining liquidity, will allow us to continue to execute our business plans in a prudent manner and preserve substantial future asset values.

For the year 2022, the London Metal Exchange (LME) copper settlement prices ranged from a high of $4.87 per pound in March (record high) to a low for the year of $3.18 per pound in July, closed at $3.80 per pound on December 30, 2022, and averaged $3.99 per pound. Current physical market conditions are strong as evidenced by low levels of global exchange stocks. FCX's global customer base reports continued healthy demand for copper.

Improved market sentiment beginning in late 2022 was associated with prospects for improved demand from China, rising demand from global decarbonization initiatives, supply constraints, U.S. dollar exchange rates and low inventories. Despite near-term uncertainties in the global economy and potential volatility in the copper market, we believe the outlook for copper fundamentals in the medium- and long-term are favorable, with third-party studies indicating that demand for copper may double in 15 years as a result of global decarbonization trends. We believe substantial new mine supply development will be required to meet the goals of the global energy transition, and higher copper prices will be required to support new mine supply development.

**COPPER, GOLD AND MOLYBDENUM** 

The following provides a summary of our primary natural resources - copper, gold and molybdenum. Refer to MD&A for further discussion of historical and current market prices of these commodities and Item 1A. "Risk Factors" for discussion of factors that can cause price fluctuations.

**Copper**

Copper is an internationally traded commodity, and its prices are determined by the major metals exchanges - the LME, Commodity Exchange Inc. (COMEX) and Shanghai Futures Exchange. Prices on these exchanges generally reflect the worldwide balance of copper supply and demand, and can be volatile and cyclical.

In general, demand for copper reflects the rate of underlying world economic growth, particularly in industrial production and construction. According to Wood Mackenzie, a widely followed independent metals market consultant, copper's end-use markets (and their estimated shares of total consumption) are electrical applications

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

(28%), construction (27%), consumer products (22%), transportation (12%) and industrial machinery (11%). We believe copper will continue to be essential in these basic uses as well as contribute significantly to new technologies for clean energy, to advance communications and to enhance public health. Examples of areas we believe will require additional copper in the future include: (i) high efficiency motors, which consume up to 75% more copper than a standard motor; (ii) electric vehicles, which consume up to four times the amount of copper in terms of weight compared to vehicles of similar size with an internal combustion engine, and require copper-intensive charging station infrastructure to refuel; and (iii) renewable energy such as wind and solar, which consume four to five times the amount of copper compared to traditional fossil fuel generated power.

**Gold**

Gold is used for jewelry, coinage and bullion as well as various industrial and electronic applications. Gold can be readily sold on numerous markets throughout the world. Benchmark prices are generally based on London Bullion Market Association (London) quotations.

**Molybdenum**

Molybdenum is a key alloying element in steel and the raw material for several chemical-grade products used in catalysts, lubrication, smoke suppression, corrosion inhibition and pigmentation. Molybdenum-based chemicals are used to produce high-purity molybdenum metal used in electronics such as flat-panel displays and in super alloys used in aerospace. Reference prices for molybdenum are available in several publications, including *Platts Metals Daily*, *CRU Prices Service* and *Fastmarkets Metals Bulletin*.

**PRODUCTS AND SALES**

Our consolidated revenues for 2022 primarily included sales of copper (77%), gold (14%) and molybdenum (6%). For the three years ended December 31, 2022, the only customer that accounted for 10% or more of our consolidated revenues was PT Smelting (PT-FI's 39.5% owned copper smelter and refinery - refer to "Smelting Facilities and Other Mining Properties" for further discussion, including that on January 1, 2023, PT-FI's commercial arrangement with PT Smelting converted to a tolling arrangement). Refer to Note 16 for a summary of our consolidated revenues and operating income (loss) by business segment and geographic area.

**Copper Products**

We are one of the world's leading producers of copper concentrate, cathode and continuous cast copper rod. During 2022, 61% of our mined copper was sold in concentrate, 18% as cathode and 21% as rod from our North America operations. The copper ore from our mines is generally processed either by smelting and refining or by solution extraction and electrowinning (SX/EW) as described below.

*<u>Copper Concentrate</u>*. We produce copper concentrate at six of our mines in which mined ore is crushed and treated to produce a copper concentrate with copper content of approximately 20% to 30%. In North America, copper concentrate is produced at the Morenci, Bagdad, Sierrita and Chino mines, and a significant portion is shipped to our Miami smelter in Arizona for further processing. Copper concentrate is also produced at the Cerro Verde mine in Peru and the Grasberg minerals district in Indonesia.

*<u>Copper Cathode</u>*. We produce copper cathode at our electrolytic refinery located in El Paso, Texas, and at nine of our mines.

SX/EW cathode is produced from the Morenci, Bagdad, Safford, Sierrita, Miami, Chino and Tyrone mines in North America, and from the Cerro Verde and El Abra mines in South America*.* For ore subject to the SX/EW process, the ore is placed on stockpiles and copper is extracted from the ore by dissolving it with a weak sulfuric acid solution. The copper content of the solution is increased in two additional SX stages, and then the copper-bearing solution undergoes an EW process to produce cathode that is, on average, 99.99% copper. Our copper cathode is used as the raw material input for copper rod, brass mill products and for other uses.

Copper cathode is also produced at Atlantic Copper (our wholly owned copper smelting and refining unit in Spain) and PT Smelting. Copper concentrate is smelted (*i.e.*, subjected to extreme heat) to produce copper anode, which weighs between 800 and 900 pounds and has an average copper content of 99.5%. The anode is further treated by electrolytic refining to produce copper cathode, which weighs between 100 and 350 pounds and has an average copper content of 99.99%. Refer to "Mining Operations - Smelting Facilities and Other Mining Properties" for further discussion of Atlantic Copper and PT Smelting.

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

*<u>Continuous Cast Copper Rod</u>*. We manufacture continuous cast copper rod at our facilities in El Paso, Texas and Miami, Arizona, primarily using copper cathode produced at our North America copper mines.

**Copper Sales**

*<u>North America</u>*. The majority of the copper produced at our North America copper mines and refined in our El Paso, Texas refinery is consumed at our rod plants to produce copper rod, which is then sold to wire and cable manufacturers. The remainder of our North America copper production is sold in the form of copper cathode or copper concentrate under U.S. dollar-denominated annual contracts. Generally, copper cathode is sold to rod, brass or tube fabricators. Cathode and rod contract prices are generally based on the prevailing COMEX monthly average settlement price for the month of shipment and include a premium. During 2022, our North America mines shipped 7% of their copper concentrate sales volumes to Atlantic Copper for smelting and refining and sold as copper anode and copper cathode by Atlantic Copper.

*<u>South America</u>*. Production from our South America mines is sold as copper concentrate or copper cathode under U.S. dollar-denominated, annual and multi-year contracts. During 2022, our South America mines sold approximately 75% of their copper production in concentrate and 25% as cathode. During 2022, 4% of our South America mines' copper concentrate sales volumes were shipped to Atlantic Copper for smelting and refining and sold as copper anode and copper cathode by Atlantic Copper.

Substantially all of our South America copper concentrate and cathode sales contracts provide final copper pricing in a specified future month (generally one to four months from the shipment date) primarily based on quoted LME monthly average settlement copper prices. Revenues from our South America concentrate sales are recorded net of royalties and treatment charges (*i.e.,* fees paid to smelters that are generally negotiated annually). In addition, because a portion of the metals contained in copper concentrate is unrecoverable from the smelting process, revenues from our South America concentrate sales are also recorded net of allowances for unrecoverable metals, which are a negotiated term of the contracts and vary by customer.

*<u>Indonesia</u>*. PT-FI has historically sold its production in the form of copper concentrate, which contains significant quantities of gold and silver, primarily under U.S. dollar-denominated, long-term contracts. PT-FI also sells a small amount of copper concentrate in the spot market. Following is a summary of PT-FI's aggregate percentage of concentrate sales to unaffiliated third parties, PT Smelting and Atlantic Copper for the years ended December 31:

| | | | |
|:---|:---|:---|:---|
| | 2022 | 2021 | 2020 |
| Third parties | 61% | 55% | 48% |
| PT Smelting | 34 | 41 | 50 |
| Atlantic Copper | 5 | 4 | 2 |

Substantially all of PT-FI's sales contracts provide final copper pricing in a specified future month (generally one to four months from the shipment date) primarily based on quoted LME monthly average settlement copper prices. Revenues from PT-FI's concentrate sales are recorded net of royalties, export duties, treatment charges and allowances for unrecoverable metals.

Beginning in 2023, PT-FI's commercial arrangement with PT Smelting converted to a tolling arrangement. Under the arrangement, PT-FI pays PT Smelting a tolling fee to smelt and refine its concentrate and will retain title to all products for sale to third parties (*i.e.,* there are no further sales from PT-FI to PT Smelting). Refer to MD&A and Note 3 for further discussion.

Refer to Item 1A. "Risk Factors" for discussion of Indonesia regulations regarding PT-FI's concentrate exports.

**Gold Products and Sales**

We produce gold almost exclusively from our mines in the Grasberg minerals district. The gold we produce is primarily sold as a component of our copper concentrate or in slimes, which are a product of the smelting and refining process. Gold generally is priced at the average London price for a specified month near the month of shipment. Revenues from gold sold as a component of our copper concentrate are recorded net of treatment charges, royalties, export duties and allowances for unrecoverable metals. Revenues from gold sold in slimes are recorded net of refining charges.

**Molybdenum Products and Sales**

According to Wood Mackenzie, we are the world's largest producer of molybdenum and molybdenum-based chemicals. In addition to production from the Henderson and Climax molybdenum mines, we produce molybdenum concentrate at certain of the North America copper mines and the Cerro Verde copper mine in Peru. The majority of our molybdenum concentrate is processed in our own conversion facilities. Our molybdenum sales are primarily priced based on the average published *Platts Metals Daily* price for the month prior to the month of shipment.

**GOVERNMENTAL REGULATIONS**

Our operations are subject to a broad range of laws and regulations imposed by governments and regulatory bodies, both in the U.S. and internationally. These regulations touch all aspects of our operations, including how we extract, process and explore for minerals and how we conduct our business, including regulations governing matters such as mining rights, environmental and reclamation matters, climate change, occupational health and safety and human rights.

**Mining Rights**

We conduct our mining and exploration activities pursuant to concessions granted by, or under contracts with, the host government in the countries where we operate. These countries include, among others, the U.S., Peru, Chile and Indonesia. Mining rights include our license to operate and involve our payment of applicable taxes and royalties to the host governments. The concessions and contracts are subject to the political risks associated with the host countries. For information about mining rights, governmental agreements, licenses to operate, and tax regulations and matters refer to "Mining Operations" below, Item 1A. "Risk Factors" and Notes 3, 11, 12 and 13.

**Environmental and Reclamation Matters** 

Our operations are subject to extensive and complex laws and regulations, including environmental laws and regulations governing the generation, storage, treatment, transportation and disposal of hazardous substances; solid waste disposal; air emissions; wastewater discharges; remediation, restoration and reclamation of environmental contamination, including mine closures and reclamation; protection of endangered and threatened species and designation of critical habitats; and other related matters. In addition, we must obtain regulatory permits and approvals to start, continue and expand operations. As a mining company, compliance with environmental, health and safety laws and regulations is an integral and costly part of our business. We conduct our operations in a manner that aims to protect public health and the environment, and we believe our operations are in compliance with applicable laws and regulations in all material respects.

At December 31, 2022, we had $1.7 billion recorded in our consolidated balance sheet for environmental obligations and $3.0 billion recorded for asset reclamation obligations. We incurred environmental capital expenditures and other environmental costs (including our joint venture partners' shares) to comply with applicable environmental laws and regulations that affect our operations totaling $0.4 billion in 2022 and $0.3 billion in both 2021 and 2020. For 2023, we expect to incur approximately $0.6 billion of aggregate environmental capital expenditures and other environmental costs. The timing and amounts of estimated payments could change as a result of changes in regulatory requirements, changes in scope and costs of reclamation activities, the settlement of environmental matters and the rate at which actual spending occurs on continuing matters.

<u>United States</u>. Laws such as the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (CERCLA) and similar state laws may expose us to joint and several liability for environmental damages caused by our operations, or by previous owners or operators of properties we acquired or are currently operating or at sites where we previously sent materials for processing, recycling or disposal. We have substantial obligations for environmental remediation on mining properties previously owned or operated by FMC and certain of its affiliates.

We are required by U.S. federal and state laws and regulations to provide financial assurance sufficient to allow a third party to implement approved closure and reclamation plans for our mining properties if we are unable to do so. Most of our financial assurance obligations are imposed by state laws that vary significantly by jurisdiction, depending on how each state regulates land use and groundwater quality. The U.S. Environmental Protection Agency (EPA) and state agencies may also require financial assurance for investigation and remediation actions that are required under settlements of enforcement actions under CERCLA or similar state laws.

Regulations have been considered at various governmental levels to increase financial responsibility requirements both for mine closure and reclamation. In 2019, legislation was enacted in Colorado that eliminates our ability to use

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

parent company guarantees and requires proof of an end date for water treatment as a condition of permit issuance authorizing mining operations, with some exceptions for existing operations. In 2018, EPA concluded a rulemaking that considered the need for financial responsibility for hardrock mining operations under CERCLA by publishing its determination that it did not intend to require financial responsibility for the hardrock mining industry sector. In 2019, the District of Columbia Circuit upheld the EPA's decision. In connection with the presidential executive order issued on January 20, 2021, EPA will review this final action, though the timing of its review is unknown. During 2022, in connection with a presidential executive order issued on February 24, 2021, the Federal government established an Interagency Working Group (IWG) led by the Department of Interior (DOI) with expertise in mine permitting and environmental law "to identify gaps in statutes and regulations that may need to be updated to ensure new production meets strong environmental standards throughout the lifecycle of the project." During 2022, the IWG received more than 31,600 comments in response to multiple questions in a request for information regarding possible changes to legislation, regulation and policies that affect the mining sector. Financial assurance as well as environmental requirements governing hardrock mining continue to be key topics in comments to DOI.

Our U.S. mining operations are also subject to regulations under the Endangered Species Act that are intended to protect species listed by the DOI's Fish & Wildlife Service (FWS) as endangered or threatened, along with critical habitat designated by FWS for these listed species. The regulations may affect the ability of landowners, including us, to obtain federal permits or authorizations needed for expansion of our operations, and may also affect our ability to obtain, retain or deliver water to some operations.

New or revised environmental regulatory requirements are frequently proposed, many of which result in substantially increased costs for our business, including those regarding financial assurance discussed above and in Item 1A. "Risk Factors." For example, our Miami, Arizona, smelter processes a significant portion of the copper concentrate produced by our North America copper mines. In 2022, EPA proposed to revise the standards for hazardous air pollutants from primary copper smelters and is now in the process of considering comments and collecting additional data. EPA may issue a new proposal after considering these comments and data, and any proposal could impose additional requirements on our operations. We may be required to modify our systems or install additional equipment to address findings, new requirements or for other reasons, which could result in significant costs, including increased capital expenditures and operating costs, and could adversely impact our business.

EPA and state agencies continue to consider regulations for man-made organic compounds that could be present in soil, groundwater and surface water at our existing and former operations. These regulations may include drinking water standards, hazardous waste requirements, and hazardous substance designations for Perfluorooctanesulfonic and Perfluorooctanoic acids. EPA is also considering how to reduce lead exposure in the environment under multiple environmental programs. Certain federal and state health agencies also support more stringent lead cleanup levels. EPA expects to make substantial progress on these proposals in 2023, and changes to EPA's lead cleanup levels could result in material increases to our environmental reserves for ongoing residential property cleanup projects near former smelter sites.

On January 18, 2023, the final revised definition of the "waters of the United States" issued by EPA and U.S. Army Corps of Engineers was published. The final rule emphasizes a case-by-case approach to "waters of the United States" for tributaries and may impose significant additional restrictions on land uses in remote and arid areas. Although court decisions can affect the scope of the final rule and legal challenges have already been filed, we will likely need federal authorization under the Clean Water Act to expand some of our operations.

For information about environmental laws and regulations, litigation and related costs, and reclamation matters related to our North America operations, refer to "Mining Operations" below, Item 1A. "Risk Factors," Item 3 "Legal Proceedings" and Notes 1 and 12.

<u>South America</u>. *Peru.* In 2005, Peru enacted the General Environmental Law (Law No. 28611), which establishes the main environmental guidelines and principles applicable in Peru. Pursuant to the General Environmental Law, Ministry of Energy and Mines (MINEM) issued national environmental regulations, which have gradually replaced prior guidelines governing governmental agencies environmental competencies. The Environmental Evaluation and Oversight Agency has the authority to inspect mining operations and fine companies that fail to comply with prescribed environmental regulations and their approved environmental assessments.

Cerro Verde is subject to regulation under the Mine Closure Law administered by MINEM. Under the closure regulations, mines must submit a closure plan that includes the reclamation methods, closure cost estimates, methods of control and verification, closure and post-closure plans, and financial assurance. In compliance with the requirement for five-year updates, Cerro Verde is preparing to submit its updated closure plan and cost estimate in February 2023.

The Cerro Verde mine has developed and continues to implement detailed, comprehensive mine waste and tailings management programs to meet the applicable Peru waste regulations and our environmental management practices. These programs incorporate commitments included in the Environmental and Social Impact Studies and the Engineer of Record designs, for the specific cases of tailings storage facilities and certain leach pad stockpiles. The site also follows our Tailings Management Policy, which outlines our continued commitment to managing tailings responsibly and addresses the implementation of the Global Industry Standard on Tailings Management for the tailings storage facilities.

For information about environmental laws and regulations and reclamation matters related to our Peru operations refer to "Mining Operations" below, Item 1A. "Risk Factors" and Note 12.

*Chile.* El Abra is subject to regulation under the Mine Closure Law administered by the Chile Mining and Geology Agency. In compliance with the requirement for five-year updates, in November 2018, El Abra submitted an updated plan with closure cost estimates based on the existing approved closure plan. Approval of the updated closure plan and cost estimates was received in August 2020, and did not result in a material increase to closure costs.

For information about environmental laws and regulations and reclamation matters related to our Chile operations refer to refer to Item 1A. "Risk Factors" and Note 12.

<u>Indonesia</u>. PT-FI holds multiple permits from national, provincial, and regency regulatory agencies, including groundwater use permits, effluent and air discharge permits, solid and hazardous waste storage and management permits and protection of forest borrow-to-use permits. Where permits have specific terms, renewal applications are made to the relevant regulatory authority as required, prior to the end of the permit term.

In December 2018, Indonesia's Ministry of Environment and Forestry (MOEF) issued a revised environmental permit to PT-FI to address certain operational activities that it alleged were inconsistent with earlier studies. PT-FI and the MOEF also established a new framework known as the Tailings Management Roadmap for continuous improvement in environmental practices at PT-FI's operations, including initiatives that will examine options to potentially increase tailings retention and to evaluate large scale beneficial uses of tailings within Indonesia. The third-party expert nominated by MOEF to perform the framework evaluation submitted its report to the MOEF in June 2021. In 2022, PT-FI continued to work with MOEF on the Tailings Management Roadmap objectives. This included further reduction of non-tailings sediment entering the tailings management area, construction of permeable groins in the estuary portion of the tailings management area to increase sedimentation and reduce erosion, as well as continue pursuing beneficial uses of tailings in infrastructure and other projects.

Permitting continues to progress for certain facilities related to the expansion of underground mining production operations as well as for additional protection structures necessary to continue to contain the tailings within the approved lowlands tailings management areas. In 2020, PT-FI initiated a new environmental impact analysis (called an Analisis Mengenai Dampak Lingkungan or AMDAL) in preparation for the proposed activities associated with the transition from Grasberg surface to underground operations. PT-FI continues to work with the MOEF to complete the approval requirements of the AMDAL, which is currently estimated to be received in 2023. PT-FI has completed the initial regulatory review of technical approvals associated with the current AMDAL filing and is now undergoing AMDAL Commission review and public consultations.

A detailed mine closure plan and 5-year reclamation plan have been approved by Indonesia regulators as required by Indonesia law. The plans are reviewed annually and revised every five years. Required reclamation bonds are in place. In the future, additional approval will be required for the diversion of the Aghawagon/Otomona River out of the tailings management area at the end of mine life. In 2019, PT-FI completed and received approval on an updated mine closure plan to reflect Grasberg minerals district production operations until 2041. PT-FI has complied with the annual renewal of the financial guarantees corresponding to the closure plan.

For information about environmental laws and regulations and reclamation matters related to our Indonesia operations, refer to "Mining Operations" below, Item 1A. "Risk Factors" and Notes 12 and 13.

**Climate Change**

In many of the jurisdictions in which we operate, governmental bodies are increasingly enacting legislation and regulations in response to the potential impacts of climate change. For example, as a result of the 2015 Paris Agreement, a number of governments, including the U.S., have pledged "Nationally Determined Contributions" to control and reduce greenhouse gas emissions (GHG). Additionally, the pledges made as part of the 2021 Glasgow Climate Pact could result in further policy changes in many of the jurisdictions in which we operate. Further, several states in the U.S., including Colorado and New Mexico, have advanced goals reducing or eliminating fossil fuel-based energy production. Carbon tax legislation also has been adopted in jurisdictions where we operate, including Indonesia, and we expect that such carbon taxes and other carbon pricing mechanisms will increase over time. Further, in March 2021, the SEC proposed new climate-related disclosure rules, which if finalized as expected in 2023, would require new climate-related disclosures in SEC filings and audited financial statements, including certain climate-related metrics and GHG emissions data, information about climate-related targets and goals, transition plans, if any, and attestation requirements. While it is not yet possible to reasonably estimate the nature, extent, timing and cost or other impacts of any future carbon pricing mechanisms, other climate change regulatory programs or future legislative action that may be enacted, we anticipate that we will dedicate more resources and money to comply and remediate in response to legislative or regulatory changes.

For information about the potential impacts of climate change and related regulations, refer to Item 1A. "Risk Factors."

**Health and Safety**

Management believes that safety and health considerations are integral to, and compatible with, all other functions in the organization and that proper safety and health management will enhance production and reduce costs. As a result, we consider the safety and health of our workforce as one of our highest priorities. We are subject to extensive regulation of worker health and safety, including the requirements of the U.S. Occupational Safety and Health Act and similar laws of other jurisdictions. In the U.S., the operation of our mines is subject to regulation by the U.S. Mine Safety and Health Administration (MSHA) under the Federal Mine Safety and Health Act of 1977 (Mine Act). MSHA inspects our mines on a regular basis and issues citations and orders when it believes a violation has occurred under the Mine Act. Additionally, in the U.S. various state agencies have concurrent jurisdiction arising under state law that regulate worker health and safety in both our industrial facilities and mines. If regulatory inspections result in an alleged violation, we may be subject to fines and penalties and, in instances of alleged significant violations, our mining operations or industrial facilities could be subject to temporary or extended closures. Refer to Exhibit 95.1 to this Form 10-K for additional information regarding certain orders and citations issued by MSHA for our operations during the year ended December 31, 2022. For information about health and safety, refer to "Human Capital" below and Item 4. "Mine Safety Disclosures."

**Human Rights**

We have adopted policies that govern our working relationships with the communities and governments where we operate and that are designed to guide our practices and programs in a manner that respects human rights and the culture of the local people impacted by our operations. For information about human rights, refer to "Community and Human Rights" below.

**COMPETITION**

The top 10 producers of copper comprise approximately 42% of total worldwide mined copper production. For the year 2022, we ranked first among those producers, with approximately 7% of estimated total worldwide mined copper production. We believe our competitive position is based on the size, quality and grade of our ore bodies and our ability to manage costs compared with other producers. We have a diverse portfolio of mining operations with varying ore grades and cost structures. Our costs are driven by the location, grade and nature of our ore bodies, and the level of input costs, including energy, labor and equipment. The metals markets are cyclical, and we believe our ability to maintain our competitive position over the long term is based on our ability to acquire and develop quality deposits (including the expansion of deposits at our existing mine sites), hire, develop and retain a skilled workforce, and to manage our costs.

**MINING OPERATIONS**

**The Copper Mark**

We are committed to maintaining the validation of all of our copper producing sites with the Copper Mark, a comprehensive assurance framework designed to demonstrate the copper industry's responsible production practices. To achieve the Copper Mark, each site is required to complete an external assurance process to assess conformance with 32 environmental, social and governance (ESG) requirements. In February 2023, PT-FI was awarded the Copper Mark and we have now achieved the Copper Mark at all 12 of our eligible copper producing sites globally.

In fourth-quarter 2022, the Copper Mark announced an extension of its framework to include molybdenum producers, among other metal producers. In February 2023, our Climax and Henderson molybdenum mines were awarded the Molybdenum Mark, making FCX the first molybdenum miner to achieve this distinction. Our four copper mines that produce by-product molybdenum (Bagdad, Cerro Verde, Morenci and Sierrita) have also been awarded the Molybdenum Mark.

**ICMM**

We are a founding member of the International Council on Mining & Metals (ICMM), an organization dedicated to a safe, fair and sustainable mining and metals industry, aiming continuously to strengthen ESG performance across the global mining and metals industry. As a member company, we are required to implement the 10 Mining Principles which define good ESG practices, and associated position statements, while also meeting 39 performance expectations and producing an externally verified sustainability report in accordance with the Global Reporting Initiative Sustainability Reporting Standards subject to the ICMM Assurance & Validation Procedure.

**Tailings Management**

We dedicate substantial financial resources and internal and external technical resources to pursue the safe management of our tailings facilities and to reduce or eliminate the number of and potential consequences of credible failure modes. Our tailings management and stewardship program, which involves qualified external Engineers of Record and periodic oversight by independent tailings Technical Review Boards and our Tailings Stewardship Team, complies with the tailings governance framework on preventing catastrophic failure of tailings storage facilities adopted by the ICMM. In August 2020, the co-conveners of the Global Tailings Review, which included ICMM, published the Global Industry Standard on Tailings Management (the Tailings Standard). The Tailings Standard includes 77 requirements across 6 key areas, including the design, construction, operation and monitoring of tailings facilities, management and governance, emergency response and long-term recovery, and public disclosure. As a member of ICMM, we are committed to implementation of the Tailings Standard by August 2023 for our tailings storage facilities with "Extreme" or "Very High" potential consequences of credible failure modes (as defined in the Tailings Standard) and by August 2025 for our remaining facilities. We believe we have the financial capacity to meet current estimated lifecycle costs, including estimated closure, post-closure and reclamation obligations associated with our tailings storage facilities. We continue to enhance our existing practices to strengthen the design, operation and closure of tailings storage facilities in an effort to reduce the risk of severe or catastrophic failure of those facilities. Refer to Item 1A. "Risk Factors" for further discussion.

**Overview of Mines**

Following are maps and descriptions of our copper and molybdenum mining operations in North America, South America and Indonesia. We consider our material mines, as defined under the disclosure requirements of Subpart 1300 of SEC Regulation S-K, to be the Morenci mine in North America, the Cerro Verde mine in Peru and the Grasberg minerals district in Indonesia. Refer to Exhibits 96.1, 96.2 and 96.3 for the Technical Report Summaries that have been prepared for our material mines.

**North America**

In the U.S., most of the land occupied by our copper and molybdenum mines, concentrators, SX/EW facilities, smelter, refinery, rod mills, molybdenum roasters and processing facilities is owned by us or is located on unpatented mining claims owned by us. Certain portions of our Bagdad, Sierrita, Miami, Chino, Tyrone, Henderson and Climax operations are located on government-owned land and are operated under a Mine Plan of Operations or other use permit. We hold various federal and state permits or leases on government land for purposes incidental to mine operations.

**Morenci**![fcx-20221231_g4.jpg](fcx-20221231_g4.jpg)

We own a 72% undivided interest in Morenci, with the remaining 28% owned by Sumitomo Metal Mining Arizona, Inc. (15%) and SMM Morenci, Inc. (13%). Each partner takes in kind its share of Morenci's production.

Morenci is an open-pit copper mining complex that has been in continuous operation since 1939 and previously was mined through underground workings. In the 1880s, Phelps Dodge & Company (Phelps Dodge) first invested in the area, and through acquisition, consolidated all mining operations in the area by the 1920s. Phelps Dodge was acquired by FCX in 2007. Morenci is located in Greenlee County, Arizona, approximately 50 miles northeast of Safford on U.S. Highway 191. The property is located at latitude 33.07 degrees north and longitude 109.35 degrees west using the World Geodetic System (WGS) 84 coordinate system. The site is accessible by a paved highway and a railway spur.

The Morenci mine is a porphyry copper deposit that has oxide, secondary sulfide and primary sulfide mineralization. The predominant oxide copper mineral is chrysocolla. Chalcocite is the most important secondary copper sulfide mineral, with chalcopyrite as the dominant primary copper sulfide.

The Morenci operation consists of two concentrators with a milling design capacity of 132,000 metric tons of ore per day, which produce copper and molybdenum concentrate (one of Morenci's concentrators, which has a milling capacity of approximately 50,000 metric tons of ore per day, was restarted in July 2021 and resumed operating at full capacity in early 2022); a 72,500 metric ton-per-day, crushed-ore leach pad and stacking system; a low-grade run-of-mine (ROM) leaching system; four SX plants; and three EW tank houses that produce copper cathode. Total EW tank house capacity is approximately 900 million pounds of copper per year. Morenci's available mining fleet consists of one hundred and forty-six 236-metric-ton haul trucks loaded by 13 electric shovels with bucket sizes ranging from 47 to 57 cubic meters. Morenci's mining fleet is capable of moving an average of 815,000 metric tons of material per day. Our share of Morenci's net property, plant, equipment (PP&E) and mine development costs at December 31, 2022, totaled $2.1 billion.

Morenci's production, including our joint venture partners' share, totaled 0.9 billion pounds of copper and 4 million pounds of molybdenum in 2022, 0.9 billion pounds of copper and 5 million pounds of molybdenum in 2021, and 1.0 billion pounds of copper and 6 million pounds of molybdenum in 2020.

Morenci is located in a desert environment with rainfall averaging 13 inches per year. The highest bench elevation is 1,900 meters above sea level and the ultimate pit bottom is expected to have an elevation of 550 meters above sea level. The Morenci operation encompasses approximately 61,700 acres, comprising 51,300 acres of fee lands and 10,400 acres of unpatented mining claims held on public mineral estate and numerous state or federal permits, easements and rights-of-way.

The Morenci operation's electrical power is supplied by our wholly owned subsidiary, The Morenci Water & Electric Company (MW&E). MW&E sources its generation services through our wholly owned subsidiary, Freeport-McMoRan Copper & Gold Energy Services LLC, through capacity rights at the Luna Energy Facility in Deming, New Mexico, and other power purchase agreements. Although we believe the Morenci operation has sufficient water sources to support current operations, we are a party to litigation that may impact our water right claims or rights to continued use of currently available water supplies, which could adversely affect our water supply for the Morenci operation. Refer to "Governmental Regulations" above, Item 1A. "Risk Factors" and Item 3. "Legal Proceedings" for further discussion.

**Bagdad**

![fcx-20221231_g5.jpg](fcx-20221231_g5.jpg)

Our wholly owned Bagdad mine is an open-pit copper and molybdenum mining complex that has been in continuous operations since 1945 and prior mining was conducted through underground workings. Bagdad is located in Yavapai County in west-central Arizona, approximately 60 miles west of Prescott and 100 miles northwest of Phoenix. The property can be reached by U.S. Highway 93 to State Route 97 or Arizona Highway 96, which ends at the town of Bagdad. The closest railroad is at Hillside, Arizona, 24 miles southeast on Arizona Highway 96.

The Bagdad mine is a porphyry copper deposit containing both sulfide and oxide mineralization. Chalcopyrite and molybdenite are the dominant primary sulfides and are the primary economic minerals in the mine. Chalcocite is the most common secondary copper sulfide mineral, and the predominant oxide copper minerals are chrysocolla, malachite and azurite.

The Bagdad operation consists of a concentrator with a milling design capacity of 77,100 metric tons of ore per day that produces copper and molybdenum concentrate, a SX/EW plant that can produce approximately 9 million pounds per year of copper cathode from solution generated by low-grade stockpile leaching, and a pressure-leach plant to process molybdenum concentrate. The available mining fleet consists of thirty-four 235-metric-ton haul trucks loaded by eight electric shovels with bucket sizes ranging from 30 to 48 cubic meters, which are capable of moving an average of 236,000 metric tons of material per day. Bagdad's net PP&E and mine development costs at December 31, 2022, totaled $0.7 billion.

We are planning an expansion to double the concentrator capacity of the Bagdad operation. We are engaging stakeholders and are conducting a feasibility study, which is expected to be completed in 2023. The timing of future development will be dependent on market conditions, labor and supply chain considerations and other economic factors. Refer to Item 1A. "Risk Factors" for further discussion.

Bagdad's production totaled 165 million pounds of copper and 9 million pounds of molybdenum in 2022, 184 million pounds of copper and 9 million pounds of molybdenum in 2021, and 216 million pounds of copper and 11 million pounds of molybdenum in 2020.

Bagdad is located in a desert environment with rainfall averaging 15 inches per year. The highest bench elevation is 1,250 meters above sea level and the ultimate pit bottom is expected to be 120 meters above sea level. The Bagdad operation encompasses approximately 51,200 acres, comprising 40,000 acres of fee lands and 11,200 acres of unpatented mining claims held on public mineral estate and numerous state or federal permits, easements and rights-of-ways.

Bagdad receives electrical power from Arizona Public Service Company. We believe the Bagdad operation has sufficient water sources to support current operations.

**Safford, including Lone Star**![fcx-20221231_g4.jpg](fcx-20221231_g4.jpg)

Our wholly owned Safford mine is an open-pit copper mining complex that has been in operation since 2007. Safford is located in Graham County, Arizona, 8 miles north of the town of Safford and 170 miles east of Phoenix. The site is accessible by paved county road off U.S. Highway 70.

The Safford mine includes three copper deposits that have oxide mineralization overlaying primary copper sulfide mineralization. The predominant oxide copper minerals are chrysocolla and copper-bearing iron oxides with the predominant copper sulfide material being chalcopyrite. The only Safford deposit currently being mined is Lone Star, which began leaching operations in the second half of 2020 and is increasing its operating rates to achieve targeted production of approximately 300 million pounds of copper per year from oxide ores in 2023 (compared with the initial design of 200 million pounds per year). The oxide project at Lone Star advances the opportunity for development of the underlying, large-scale sulfide resources. We are conducting follow-on exploration in the area to support metallurgical testing and mine development planning for a potential significant long-term investment to build additional scale on an economically attractive basis.

Safford is a mine-for-leach operation that produces copper cathode. The operation consists of three open pits, of which only Lone Star is currently being mined, feeding a crushing facility with a design capacity of 103,500 metric tons of ore per day. The crushed ore is delivered to a leach pad by a series of overland and portable conveyors. Leach solutions feed a SX/EW facility with a capacity of 305 million pounds of copper per year.

Cerro Verde is an open-pit copper and molybdenum mining complex that has been in operation since 1976. Cerro Verde is located 20 miles southwest of Arequipa, Peru. Prior to being acquired in 1994 by a predecessor of Phelps Dodge, the mine was previously operated by the Peru government. The property is located at latitude 16.53 degrees south and longitude 71.58 degrees west using the WGS 84 coordinate system. The site is accessible by paved highway. Cerro Verde's copper cathode and concentrate production that is not sold locally is transported approximately 70 miles by truck and by rail to the Port of Matarani for shipment to international markets. Molybdenum concentrate is transported by truck to either the Ports of Callao or Matarani for shipment.

The Cerro Verde mine is a porphyry copper deposit that has oxide, secondary sulfide and primary sulfide mineralization. The predominant oxide copper minerals are brochantite, chrysocolla, malachite and copper "pitch." Chalcocite and covellite are the most important secondary copper sulfide minerals. Chalcopyrite and molybdenite are the dominant primary sulfides.

Cerro Verde's operation consists of two concentrating facilities with a total milling design capacity of 360,000 metric tons of ore per day and SX/EW leaching facilities. As a result of several efficiency initiatives implemented over the past several years, Cerro Verde's two concentrators were able to achieve a combined average milling rate exceeding 400,000 metric tons of ore per day in 2022. Leach copper production is derived from a 39,000-metric-ton-per-day crushed leach facility and a 100,000-metric-ton-per-day ROM leach system. This SX/EW leaching operation has a capacity of approximately 200 million pounds of copper per year.

The available fleet consists of fifty-four 300-metric-ton haul trucks and ninety-three 245-metric-ton haul trucks (17 of which are currently on standby) and seven leased haul trucks (three 360-metric-ton and four 363-metric-ton) loaded by thirteen electric shovels with bucket sizes ranging in size from 33 to 57 cubic meters and two hydraulic shovels with a bucket size of 21 cubic meters (one of them is currently on standby). This fleet is capable of moving an average of approximately 1,000,000 metric tons of material per day. Cerro Verde's net PP&E and mine development costs at December 31, 2022, totaled $6.0 billion.

Cerro Verde's production totaled 1.0 billion pounds of copper and 23 million pounds of molybdenum in 2022, 0.9 billion pounds of copper and 21 million pounds of molybdenum in 2021, and 0.8 billion pounds of copper and 19 million pounds of molybdenum in 2020.

Cerro Verde is located in a desert environment with rainfall averaging 1.5 inches per year and is in an active seismic zone. The highest bench elevation is 2,768 meters above sea level and the ultimate pit bottom is expected to be 1,538 meters above sea level. The Peru general mining law and Cerro Verde's mining stability agreement grant the surface rights of mining concessions located on government land. Government land obtained after 1997 must be leased or purchased. Cerro Verde has a mining concession covering approximately 178,000 acres, including 62,000 acres of surface rights and access to 14,600 acres granted through an easement from the Peru National Assets Office, plus 150 acres of owned property, and 1,151 acres of rights-of-way outside the mining concession area leased from both government agencies and private parties.

Cerro Verde currently receives electrical power, including hydro-generated power, under long-term contracts with ElectroPeru and Engie Energia Peru S.A.

Water for our Cerro Verde processing operations comes from renewable sources through a series of storage reservoirs on the Río Chili watershed that collect water primarily from seasonal precipitation and from wastewater collected from the city of Arequipa and treated at a wastewater treatment plant.

El Abra's copper production totaled 202 million pounds in 2022, 160 million pounds in 2021 and 159 million pounds in 2020. Higher mining and stacking activities at El Abra resulted in a 26% increase in copper production for the year 2022, compared with the year 2021 (which was impacted by COVID-19 protocols).

El Abra's large sulfide resource supports a potential major mill project similar to the large-scale concentrator constructed at Cerro Verde in 2015. Technical and economic studies continue to be evaluated to determine the optimal scope and timing for the sulfide project. We are advancing plans to invest in water infrastructure to provide options to extend existing operations, while continuing to monitor potential changes in Chile's regulatory and fiscal matters. We will defer major investment decisions pending clarity on such matters.

El Abra is located in a desert environment with rainfall averaging less than one inch per year and is in an active seismic zone. The highest bench elevation is 4,225 meters above sea level and the ultimate pit bottom is expected to be 3,385 meters above sea level. El Abra controls a total of approximately 183,600 acres of mining claims covering the ore deposit, stockpiles, process plant, and water wellfield and pipeline. In addition, El Abra has land surface rights for the road between the processing plant and the mine, the water wellfield, power transmission lines and for the water pipeline from the Salar de Ascotán aquifer.

El Abra currently receives electrical power under a long-term contract with Engie Energia Chile S.A. Water for our El Abra processing operations comes from the continued pumping of groundwater from the Salar de Ascotán aquifer pursuant to regulatory approval. We believe El Abra has sufficient water rights and regulatory approvals to support current operations. Refer to "Governmental Regulations" above and Item 1A. "Risk Factors" for further discussion.

<u>Ownership</u>. PT-FI is a limited liability company organized under the laws of the Republic of Indonesia. On December 21, 2018, we completed the transaction with the Indonesia government regarding PT-FI's long-term mining rights and share ownership (the 2018 Transaction). Following the 2018 Transaction, we have a 48.76% share ownership in PT-FI and the remaining 51.24% share ownership is collectively held by PT Indonesia Asahan Aluminum (Persero) (PT Inalum, also known as MIND ID), an Indonesia state-owned enterprise, and PT Indonesia Papua Metal Dan Mineral (formerly known as PT Indocopper Investama), which is expected to be owned by MIND ID and the provincial/regional government in Central Papua, Indonesia. The arrangements related to the 2018 Transaction also provided for us and the other pre-transaction PT-FI shareholders to initially retain the economics of the revenue and cost sharing arrangements under the former unincorporated joint venture with Rio Tinto plc (Rio Tinto). As a result, our economic interest in PT-FI approximated 81% through 2022. Beginning January 1, 2023, our economic interest in PT-FI is 48.76%. Refer to Note 3 for further discussion.

<u>IUPK</u>. Concurrent with closing the 2018 Transaction, the Indonesia government granted PT-FI a special mining license (IUPK) to replace its former Contract of Work (COW), enabling PT-FI to conduct operations in the Grasberg minerals district through 2041. Under the terms of the IUPK, PT-FI has been granted an extension of mining rights through 2031, with rights to extend mining rights through 2041, subject to PT-FI completing the construction of additional domestic smelting capacity in Indonesia and fulfilling its defined fiscal obligations to the Indonesia government. The IUPK, and related documentation, contains legal and fiscal terms and is legally enforceable through 2041. In addition, we, as a foreign investor, have rights to resolve investment disputes with the Indonesia government through international arbitration. Refer to Note 13 and Item 1A. "Risk Factors" for discussion of PT-FI's IUPK and risks associated with our Indonesia mining operations.

PT-FI's IUPK provides that exports continue through 2023, subject to force majeure considerations. Indonesia regulations require PT-FI to renew its export license annually. The current license is scheduled for renewal in March 2023 and PT-FI is preparing its renewal application. PT-FI plans to work cooperatively with the Indonesia government to continue exports as required until the smelter is fully commissioned. Refer to Item 1A. "Risk Factors" for further discussion of risks associated with PT-FI's export of copper concentrate.

<u>Mining Rights</u>. PT-FI and the Indonesia government continue to engage in preliminary discussions regarding the extension of PT-FI's mining rights under its IUPK beyond 2041. PT-FI believes an extension beyond 2041 would enable continuity of operations and the identification of additional resource development opportunities in the Grasberg minerals district.

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

<u>Indonesia Smelter Capacity</u>. Under the terms of the IUPK, PT-FI has been granted mining rights through 2031, with rights to extend its mining rights through 2041, subject to, among other things, PT-FI's completion of construction of additional domestic smelting capacity totaling 2 million dry metric tons of concentrate per year by the end of 2023 (subject to force majeure provisions) and fulfilling its defined fiscal obligations to the Indonesia government. In accordance with Indonesia regulations, PT-FI submits a smelter progress report to the Indonesia government for review every six months. Refer to "Governmental Regulations" above, Item 1A. "Risk Factors," MD&A and Notes 12 and 13 for additional discussion of the Indonesia smelter projects.

<u>Grasberg Minerals District</u>. PT-FI operates in the remote highlands of the Sudirman Mountain Range in the province of Central Papua, Indonesia, which is on the western half of the island of New Guinea. Since 1967, we and our predecessors have been the only operator of exploration and mining activities in the approximately 24,600-acre operating area. The operating area is accessible by coastal portsite facilities on the Arafura Sea and by the Timika airport. The project site is located at latitude 4.08 degrees south and longitude 137.12 degrees east using the WGS 84 coordinate system. The project area includes a 70-mile main service road from portsite to the mill complex.

PT-FI currently has three underground operating mines in the Grasberg minerals district: the Grasberg Block Cave, the Deep Mill Level Zone (DMLZ) and Big Gossan.

Production from the Grasberg minerals district totaled 1.6 billion pounds of copper and 1.8 million ounces of gold in 2022, 1.3 billion pounds of copper and 1.4 million ounces of gold in 2021, and 0.8 billion pounds of copper and 0.8 million ounces of gold in 2020. PT-FI's net PP&E and mine development costs at December 31, 2022, totaled $16.9 billion.

The installation of additional milling facilities at PT-FI is currently expected to be completed in late 2023, which would increase milling capacity to approximately 240,000 metric tons of ore per day and provide for continued annualized copper and gold production volumes of approximately 1.6 billion pounds of copper and 1.6 million ounces of gold. PT-FI is also advancing a mill recovery project with the installation of a new copper cleaner circuit that is expected to be completed in 2024 and is expected to provide incremental metal production of approximately 60 million pounds of copper and 40 thousand ounces of gold per year. Additionally, in 2021, PT-FI commenced long-term mine development activities for its Kucing Liar deposit. Refer to Item 1A. "Risk Factors" for discussion of risks associated with development projects and underground mines.

Our principal source of power for our Indonesia operations is a coal-fired power plant that we built in 1998. Diesel generators supply peaking and backup electrical power generating capacity; however, PT-FI is constructing a dual-fuel power plant that is expected to be fully commissioned in 2023 to support increased power requirements as underground mining continues to ramp up.

A combination of naturally occurring mountain streams and water derived from our underground operations provides water for our operations. Our Indonesia operations are in an active seismic zone and experience average annual rainfall of approximately 200 inches.

automated rail system. Each ore wagon typically carries 35 metric tons. The crushed ore is conveyed to surface stockpiles for processing.

*DMLZ Underground Mine*

The DMLZ ore body lies below the Deep Ore Zone (DOZ) underground mine at the 2,590-meter elevation and represents the downward continuation of mineralization in the Ertsberg East Skarn system and neighboring Ertsberg porphyry.

The DMLZ has continued its ramp-up of production. Hydraulic fracturing operations have been effective in managing rock stresses and pre-conditioning the cave following mining-induced seismic activity experienced from time to time. Ongoing hydraulic fracturing operations combined with continued undercutting and drawbell openings in the two currently active production blocks are expected to expand the cave, supporting higher production rates that are expected to average nearly 80,000 metric tons of ore per day in both 2023 and 2024 from three production blocks. As of December 31, 2022, the DMLZ underground mine had 207 open drawbells.

Ore milled from the DMLZ underground mine averaged 76,300 metric tons per day in 2022, 58,000 metric tons per day in 2021 and 28,600 metric tons per day in 2020. Production at the DMLZ underground mine is expected to continue through 2041.

The DMLZ fleet consists of over 400 pieces of mobile equipment, which includes 60 LHD units and 36 haul trucks used in production and development activities. Each production LHD unit typically carries approximately 9 metric tons of ore and transfers ore into the truck haulage system. The haul trucks have a capacity of 55 to 60 metric tons and load ore from chutes fed by the LHDs and transfer it to one of two gyratory crushers. The crushed ore is conveyed to surface stockpiles for processing.

*Big Gossan Underground Mine*

The Big Gossan ore body lies underground and adjacent to the current mill site. It is a tabular, near vertical ore body with approximate dimensions of 1,200 meters along strike and 800 meters down dip with varying thicknesses from 20 meters to 120 meters. The mine utilizes a blasthole stoping method with delayed paste backfill. Stopes of varying sizes are mined and the ore dropped down passes to a truck haulage level. Trucks are chute loaded and transport the ore to a jaw crusher. The crushed ore is then hoisted vertically via a two-skip production shaft to a level where it is loaded onto a conveyor belt. The belt carries the ore to one of the main underground conveyors where the ore is transferred and conveyed to the surface stockpiles for processing.

Ore milled from the Big Gossan underground mine averaged 7,600 metric tons per day in 2022, 7,500 metric tons per day in 2021 and 7,000 metric tons per day in 2020. Production at the Big Gossan underground mine is expected to continue through 2041.

The Big Gossan fleet consists of over 80 pieces of mobile equipment, which include 13 LHD units and 7 haul trucks used in development and production activities.

*Kucing Liar Underground Mine*

Long-term mine development activities are ongoing for PT-FI's Kucing Liar deposit in the Grasberg minerals district, which is expected to produce over 6 billion pounds of copper and 6 million ounces of gold between 2028 and the end of 2041. Pre-production development activities commenced in 2022 and are expected to continue over an approximate 10-year timeframe. Capital investments are estimated to average approximately $400 million per year over this period (including $470 million for the year 2023). At full operating rates of approximately 90,000 metric tons of ore per day, annual production from Kucing Liar is expected to approximate 550 million pounds of copper and 560 thousand ounces of gold, providing PT-FI with sustained long-term, large-scale and low-cost production. Kucing Liar will benefit from substantial shared infrastructure and PT-FI's experience and long-term success in block-cave mining.

*DOZ Underground Mine*

The DOZ ore body lies vertically below the depleted Intermediate Ore Zone. PT-FI began production from the DOZ ore body in 1989 and the ore body was depleted at the end of 2021. Ore milled from the DOZ underground mine averaged 8,700 metric tons per day in 2021 and 20,900 metric tons per day in 2020.

*Grasberg Open Pit* 

PT-FI began open-pit mining of the Grasberg ore body in 1990 and the final phase was mined during 2019. In aggregate, the Grasberg open pit produced over 27 billion pounds of copper and 46 million ounces of gold in the 30-year period from 1990 through 2019.

<u>Description of Indonesia Ore Bodies</u>*.* Our Indonesia ore bodies are located within and around two main igneous intrusions, the Grasberg monzodiorite and the Ertsberg diorite. The host rocks of these ore bodies include both carbonate and clastic rocks that form the ridge crests and upper flanks of the Sudirman Range, and the igneous rocks of monzonitic to dioritic composition that intrude them. The igneous-hosted ore bodies (the Grasberg Block Cave and portions of the DMLZ) occur as vein stockworks and disseminations of copper sulfides, dominated by chalcopyrite and, to a lesser extent, bornite. The sedimentary-rock hosted ore bodies (portions of the DMLZ and Kucing Liar and all of the Big Gossan) occur as "magnetite-rich, calcium/magnesian skarn" replacements, whose location and orientation are strongly influenced by major faults and by the chemistry of the carbonate rocks along the margins of the intrusions.

The copper mineralization in these skarn deposits is dominated by chalcopyrite, but higher bornite concentrations are common. Moreover, gold occurs in significant concentrations in all of the district's ore bodies, though rarely visible to the naked eye. These gold concentrations usually occur as inclusions within the copper sulfide minerals, though, in some deposits, these concentrations can also be strongly associated with pyrite.

The following diagram indicates the relative elevations (in meters) of our reported Indonesia ore bodies.

**Smelting Facilities and Other Mining Properties**

<u>Greenfield Smelter and Precious Metal Refinery</u>. PT-FI is actively engaged in the construction of a greenfield smelter in Gresik, Indonesia. The greenfield smelter will be owned and operated by PT-FI and have a capacity to process approximately 1.7 million metric tons of copper concentrate per year. The smelter construction is advancing and is expected to be completed during 2024.

Construction of a precious metal refinery to process gold and silver from the greenfield smelter and PT Smelting at an estimated capital cost of $400 million is in progress with commissioning also expected during 2024.

<u>Atlantic Copper</u>. Our wholly owned Atlantic Copper smelter and refinery is located on land concessions from the Huelva, Spain, port authorities, which are scheduled to expire in 2038.

The design capacity of the smelter is approximately 300,000 metric tons of copper per year, and the refinery has a capacity of 286,000 metric tons of copper per year. Atlantic Copper's anode production from its smelter totaled 215,000 metric tons of copper in 2022, 278,600 metric tons in 2021 and 275,900 metric tons in 2020. Copper cathode production from its refinery totaled 218,400 metric tons of copper in 2022, 277,000 metric tons in 2021 and 275,000 metric tons in 2020.

Atlantic Copper completed a 78-day major maintenance turnaround in 2022. Atlantic Copper's major maintenance turnarounds typically occur approximately every eight years, with shorter-term maintenance turnarounds in the interim.

Following is the allocation of Atlantic Copper's concentrate purchases from unaffiliated third parties and our copper mining operations for the years ended December 31:

Atlantic Copper is developing an e-material recycling project as a result of the significant and continued

growth in electronic waste material. Atlantic Copper's existing smelting and refining facilities provide synergies to recycle this type of material, and the project, which is expected to commence in 2025, would include an addition of a smelting furnace and associated equipment to recover copper, gold, silver, palladium, tin, nickel and platinum from e-materials. Atlantic Copper estimates that the initial project capital will approximate $325 million.

<u>PT Smelting</u>. PT Smelting, an Indonesia company, owns a copper smelter and refinery in Gresik, Indonesia. On April 30, 2021, PT-FI acquired an additional 14.5% of the outstanding common stock of PT Smelting, increasing its ownership interest to 39.5%. Mitsubishi Materials Corporation (MMC) owns the remaining 60.5% and serves as the operator of PT Smelting.

In November 2021, PT-FI completed agreements with MMC to implement the expansion of PT Smelting's capacity by 30% to 1.3 million metric tons of concentrate per year, which is expected to be completed by the end of 2023. PT-FI is funding the cost of the expansion with a loan that is expected to convert to equity, increasing its ownership in PT Smelting from 39.5% to a majority ownership once the expansion is complete. Refer to Note 3 for further discussion.

Prior to 2023, PT-FI's contract with PT Smelting provided for PT-FI to supply 100% of the copper concentrate requirements (subject to a minimum or maximum treatment charge rate) necessary for PT Smelting to produce 205,000 metric tons of copper annually on a priority basis. PT-FI could also then sell copper concentrate to PT Smelting at market rates for quantities in excess of 205,000 metric tons of copper annually.

Beginning in 2023, PT-FI's commercial arrangement with PT Smelting converted to a tolling arrangement. Under the arrangement, PT-FI pays PT Smelting a tolling fee to smelt and refine its concentrate and will retain title to all products for sale to third parties. This arrangement is not expected to result in a significant change in PT-FI's economics but will impact the timing of PT-FI's sales during 2023. We estimate that approximately 90 million pounds of copper and 120 thousand ounces of gold from PT-FI's first-quarter 2023 production will remain in inventory until final sale later in 2023.

PT Smelting received a one-year extension of its anode slimes export license, which currently expires November 3, 2023. Refer to Item 1A. "Risk Factors" for further discussion of risks associated with PT Smelting's export of anode slimes.

PT Smelting's anode production from its smelter totaled 316,700 metric tons of copper in 2022, 280,400 metric tons in 2021 and 276,900 metric tons in 2020. Copper cathode production from its refinery totaled 268,400 metric tons of copper in 2022, 256,900 metric tons in 2021 and 273,000 metric tons in 2020.

PT Smelting's maintenance turnarounds (which range from two weeks to a month to complete) typically are expected to occur approximately every two years, with short-term maintenance turnarounds in the interim. PT Smelting completed a 30-day maintenance turnaround during December 2020 and an 18-day maintenance turnaround in October 2022. PT Smelting has a planned 75-day shutdown scheduled for mid-2023 associated with its expansion project with a 7-day shutdown in fourth-quarter 2023 to complete final tie-in of the expansion project.&nbsp;&nbsp;&nbsp;&nbsp;

<u>Miami Smelter</u>. We own and operate a smelter at our Miami mining operation in Arizona. The smelter has been operating for over 100 years and has been upgraded numerous times during that period to implement new technologies, improve production and comply with air quality requirements.

The Miami smelter processes copper concentrate primarily from our North America copper mines. Concentrate processed through the smelter totaled 781,000 metric tons in 2022, 674,000 metric tons in 2021 and 764,000 metric tons in 2020, and copper anode production from the smelter totaled 202,000 metric tons in 2022, 194,000 metric tons in 2021 and 211,000 metric tons in 2020. In addition, because sulfuric acid is a by-product of smelting concentrate, the Miami smelter is also the most significant source of sulfuric acid for our North America leaching operations.

Major maintenance turnarounds are anticipated to occur approximately every two or three years for the Miami smelter. We performed a major maintenance turnaround during 2021. The next major maintenance turnaround is scheduled for the last half of 2024.

<u>Rod & Refining Operations</u>. Our Rod & Refining operations consist of conversion facilities located in North America, including a refinery in El Paso, Texas and rod mills in El Paso, Texas, and Miami, Arizona. We refine our copper anode production from our Miami smelter at our El Paso refinery. The El Paso refinery has the potential to operate at an annual production capacity of approximately 410,000 metric tons of copper cathode, which is sufficient to refine all of the copper anode we produce at our Miami smelter. Copper cathode production from the El Paso refinery totaled 208,900 metric tons in 2022, 187,300 metric tons in 2021 and 212,600 metric tons in 2020. Our El Paso refinery also produces nickel carbonate, copper telluride and autoclaved slimes material containing gold, silver, platinum and palladium.

<u>Molybdenum Conversion Facilities</u>. We process molybdenum concentrate at our conversion plants in the U.S. and Europe into such products as technical-grade molybdic oxide, ferromolybdenum, pure molybdic oxide, ammonium molybdates and molybdenum disulfide. We operate molybdenum roasters in Sierrita, Arizona; Fort Madison, Iowa; and Rotterdam, the Netherlands, and we operate a molybdenum pressure-leach plant in Bagdad, Arizona. We also produce ferromolybdenum for customers worldwide at our conversion plant located in Stowmarket, United Kingdom.

<u>Other North America Copper Mines</u>. We have five non-operating copper mines - Ajo, Bisbee, Tohono, Twin Buttes and Christmas, which are located in Arizona - that have been on care and maintenance status for several years and would require new or updated environmental studies, new permits, and additional capital investment, which could be significant, to return them to operating status.

**MINING DEVELOPMENT PROJECTS AND EXPLORATION ACTIVITIES** 

Capital expenditures totaled $3.5 billion (including $1.7 billion for major mining projects and $0.8 billion for Indonesia smelter projects) in 2022, $2.1 billion (including $1.25 billion for major mining projects and $0.2 billion for Indonesia smelter projects) in 2021 and $2.0 billion (including $1.2 billion for major mining projects and $0.1 billion for Indonesia smelter projects) in 2020. Capital expenditures for major mining projects were primarily associated with underground development activities in the Grasberg minerals district, and also included expenditures associated with the Lone Star copper leach project at our Safford mine in 2021 and 2020.

We have several projects and potential opportunities to expand production volumes, extend mine lives and develop large-scale underground ore bodies. As further discussed in MD&A, our near-term major development projects will focus on the underground development activities in the Grasberg minerals district. Considering the long-term nature and large size of our development projects, actual costs and timing could vary from estimates. Additionally, in response to market conditions, the timing of our expenditures will continue to be reviewed. We continue to review our mine development and processing plans to maximize the value of our mineral reserves.

Additionally, full development of PT-FI's underground mineral reserves at the Grasberg minerals district is expected to require approximately $3 billion (most of which will be incurred over an approximate 12-year period) of capital expenditures at our processing facilities to optimize the handling of underground ore from the Grasberg Block Cave, DMLZ and Kucing Liar deposits. Increases in power loads at these processing facilities and the underground mines are expected to require additional power generation with capital expenditures approximating $0.6 billion for new dual-fuel power generation, upgrades to existing transmission lines, and refurbishment of the existing three coal units.

Our mining exploration activities are primarily associated with our existing mines, focusing on opportunities to expand mineral reserves and resources to support development of additional future production capacity. Exploration results continue to indicate opportunities for significant future potential reserve additions at our existing properties in North America and South America. Exploration spending associated with mining operations totaled $105 million in 2022 (primarily to advance Lone Star and other opportunities at our North America copper mines), $50 million in 2021 and $34 million in 2020.

Refer to Item 1A. "Risk Factors" for further discussion of risks associated with mine development projects and exploration activities, and PT-FI's IUPK.

**SOURCES AND AVAILABILITY OF ENERGY, NATURAL RESOURCES AND RAW MATERIALS**

Our copper mining operations require significant amounts of energy, principally diesel, electricity, coal and natural gas, most of which is obtained from third parties under long-term contracts. Historically, copper prices have been correlated to various input costs, including energy and other commodity-related consumables. During 2022, prices

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

for a number of commodity-related consumables increased at a time when copper prices declined. While a number of commodity-related consumables have retreated from the highs of 2022, most cost elements remain high relative to long-term correlations. For a further discussion of risks associated with various input costs, refer to Item 1A. "Risk Factors."

Energy represented approximately 21% of our copper mine site operating costs in 2022, including purchases of approximately 230 million gallons of diesel fuel; approximately 8,400 gigawatt hours of electricity at our North America and South America copper mining operations (we generate all of our power at our Indonesia mining operation); approximately 820 thousand metric tons of coal for our coal power plant in Indonesia; and approximately 1 million MMBtu (million British thermal units) of natural gas at certain of our North America mines. Based on current cost estimates, energy is expected to approximate 24% of our copper mine site operating costs in 2023.

Our mining operations also require significant quantities of water for mining, ore processing and related support facilities. The loss of water rights for any of our mines, in whole or in part, or shortages of water to which we have rights, could require us to curtail or shut down mining operations. For a further discussion of risks and legal proceedings associated with the availability of water, refer to "Governmental Regulations" above, Item 1A. "Risk Factors" and Item 3. "Legal Proceedings."

Sulfuric acid is used in the SX/EW process and is produced as a by-product of the smelting process at our smelters and from our sulfur burners at the Safford mine. Sulfuric acid needs in excess of the sulfuric acid produced by our operations are purchased from third parties.

**HUMAN CAPITAL**

We are committed to promoting the health, safety and well-being of our workforce and striving to further strengthen our commitment to promoting an inclusive, diverse and agile workplace. We believe our global workforce is the foundation of our success. Our Board of Directors (Board) oversees our policies and implementation programs that govern our approach to management of our human capital, with the Corporate Responsibility Committee (CRC) having oversight of health and safety matters and the Compensation Committee having oversight of other human capital matters, including those relating to workforce recruitment, retention and development, pay equity and inclusion and diversity.

**Workforce**

At December 31, 2022, we had approximately 25,600 employees (12,400 in North America, 5,900 in Indonesia, 6,300 in South America and 1,000 in Europe and other locations). We also had contractors that employ personnel at many of our operations, including approximately 23,500 at the Grasberg minerals district in Indonesia, 16,600 in North America, 6,400 at our South America mining operations and 2,400 in Europe and other locations.

Approximately 30% of our global employee population is covered by collective labor agreements (CLAs). In North America, our workforce is not covered by a CLA. Our North America hourly employees choose to work directly with management utilizing our Freeport Guiding Principles, which establishes how we work together within the values of the company to achieve our collective goals.

a.In September 2022, El Abra completed negotiations with its unions on a new three-year CLA that is effective through April 2026.

b.The CLA between Atlantic Copper and its three unions expired in December 2022, but has been extended indefinitely and remains active by mutual agreement from both parties while a new agreement is negotiated.

c.In December 2022, Rotterdam implemented the wage and bonus increases agreed to during union negotiations and extended the current CLA through September 2023.

We engage openly with our employee and union leadership to negotiate and uphold labor agreements, recognizing that labor disruptions such as prolonged strikes or other work stoppages can adversely affect our business operations, our workforce and regional stakeholders. There were no strikes or lockouts at any of our operations in 2022.

**Health and Safety**

Our highest priority is the health, safety and well-being of our employees and contractors. We also aim to instill health and safety processes for our suppliers and the communities where we operate. We believe that health and safety considerations are integral to, and fundamental for, all other functions in our organization, and we understand that the health and safety of our workforce is critical to our operational efficiency and long-term success. Our global health and safety approach, "Safe Production Matters," is focused on fatality prevention and continuous improvement through the use of robust management systems, empowering safe work behaviors and strengthening our safety culture.

We focus on fatality prevention through the use of data and technology as well as behavioral science principles. Our framework for managing risks and compliance obligations is certified company wide in accordance with the ISO 45001 Health and Safety Management System (ISO 45001), most recently certified in January 2023. ISO 45001 requires third-party site-level verification of requirements, with a goal to prevent fatalities and reduce safety incidents.

As part of our commitment to providing a safe and healthy workplace, we strive to provide the training, tools and resources needed so our workforce can identify risks and consistently apply effective controls. We share information and key learnings about potentially fatal events, near misses and best practices throughout the company and engage with industry peers outside the organization to continuously improve our health and safety performance. We also review and discuss all fatalities with the CRC and the full Board.

Our objective is to achieve zero workplace fatalities and to decrease injuries and occupational illnesses. We measure our safety performance through regularly established benchmarks, including our company-wide Total Recordable Incident Rate (TRIR), which includes both employees and contractors. Regrettably, we had one work-related fatality in 2022 and two work-related fatalities in 2021. Additionally, three other fatalities occurred onsite in 2022; which, as of February 15, 2023, have not yet been classified by MSHA as independent medical episodes or work-related. We had 30 potential fatal events (PFE) in 2022 and 17 PFEs in 2021. Our TRIR per 200,000 man-hours worked was 0.77 in 2022 and 0.70 in 2021, which were higher than our 0.69 target for each year. The metal mining sector industry average per 200,000 man-hours worked reported by MSHA was 1.83 for 2022 (preliminary for the period of January 1, 2022, through September 30, 2022) and 1.71 in 2021.

In 2022, we continued to take steps to protect our workforce from COVID-19, by continuing operating protocols at each of our operating sites to contain and mitigate the risk of spread of COVID-19. We will continue to monitor, assess and update our public health crisis response, including COVID-19 protocols. Looking beyond the COVID-19 pandemic, we have committed to maintaining health benefits and offer guidance resources to support mental and physical well-being.

**Employee Engagement, Training and Development**

In addition to the health, safety and well-being of our global workforce, we have prioritized retaining a flexible, highly engaged and agile workforce. A key to our success is the ability to recruit, retain, develop and advance talented employees with diverse perspectives.

We are committed to ongoing training and development of our workforce. We focus on recruiting and retaining talented people by offering quality employment with competitive compensation and benefits as well as opportunities for professional development and growth. Strategic talent reviews and succession planning occur regularly and across all business areas. To support the advancement of our employees, we offer training and development programs encouraging advancement from within and continue to promote strong and experienced management

talent. We leverage both formal and informal programs to identify, foster and retain top talent at both the corporate and operations levels.

**Inclusion and Diversity** 

We are committed to fostering a culture that is safety focused, respectful, inclusive and representative of the communities where we operate. As a global organization that operates in diverse parts of the world, inclusion and diversity is a company priority, and we believe an inclusive and diverse workforce with a broad range of experience, knowledge, background, culture and heritage drives innovation, enhances operational performance and improves relationships with stakeholders.

We are often the largest employer in our local communities and hiring locally is a commitment we make to the host communities surrounding our operations and to our host countries. As of December 31, 2022, the vast majority of our employees are from the countries where we operate. We retain expatriate expertise for managerial and technical roles when we determine it is not available in local communities. To further these efforts, expatriates receive cultural training upon their arrival to a new location.

We aim to tailor our approach to inclusion and diversity across our global business and we seek to design programs and initiatives with standardized processes and priorities while being adaptable to site-specific or situational circumstances. We strive for, promote and foster a workplace where everyone feels a sense of belonging, is treated with respect and their opinions are valued. We believe an inclusive environment gives our people the confidence to speak up, share ideas that drive innovation and achieve operational excellence. We believe our inclusive environment is the foundation of our high-performance culture and is paramount to the long-term sustainable success of our business.

In addition to our Inclusion and Diversity Policy, our inclusion and diversity principles align with our core values of safety, respect, integrity, excellence and commitment, and are incorporated into our Principles of Business Conduct and other related policies. We have dedicated human resources team members to focus on inclusion and diversity initiatives and a cross-functional inclusion and diversity leadership team to help guide the strategy and direction of our inclusion and diversity programs. To help incentivize continued progress by our executive team on our priorities, inclusion and diversity has also been integrated into executive compensation, contributing to the sustainability component of our performance-based annual incentive program.

Additional information regarding our activities related to our people, including our workforce diversity data, can be found in our 2021 Annual Report on Sustainability and our 2021 EEO-1 Disclosure Supplement on our website. The Annual Report on Sustainability is updated annually. None of the information on, or accessible through, our website is part of this Form 10-K or is incorporated by reference herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• agricultural assistance programs

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• small and medium enterprise development programs

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• basic education programs

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cultural resources promotion and preservation programs

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• community infrastructure development

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• charitable donations

------

In 2000, we endorsed the joint U.S. State Department-British Foreign Office Voluntary Principles on Security and Human Rights (Voluntary Principles). We participated in developing these Voluntary Principles with other major natural resource companies and international human rights organizations and they are incorporated into our human rights policy. The Voluntary Principles provide guidelines for our security programs, including interaction with host-government security personnel, private security contractors and our internal security employees.

Our Human Rights Policy reflects our commitment to implementing the United Nations Guiding Principles on Business and Human Rights. We have embarked on a program to plan and conduct site-level human rights impact assessments (HRIA) at our global operations, which help us to embed human rights considerations into our business practices, including site-level sustainability risk registers. We completed HRIAs at our Arizona operations in 2022, at El Abra in 2021, at our New Mexico operations in 2018, and at Cerro Verde in 2017. In 2022, we initiated the planning phase of the HRIA at PT-FI. We also participate in a multi-industry human rights working group to gain insight from peer companies and experts in the field to learn how best practices are evolving.

We believe that our social and economic development programs are responsive to the issues raised by the local communities near our areas of operation and help us maintain good relations with the surrounding communities and avoid disruptions of mining operations. As part of our ongoing commitment to our community stakeholders, we have made and expect to continue making investments in certain social programs, including in-kind support and administration, across our global operations from time to time. Over the last three years, these investments have averaged $150 million per year. Nevertheless, social and political instability in the areas of our operations may adversely impact our mining operations. Refer to Item 1A. "Risk Factors" for further discussion.

<u>South America</u>. Cerro Verde has provided a variety of community support projects over the years. Following engagements with regional and local governments, civic leaders and development agencies, in 2006, Cerro Verde committed to support the costs for a new potable water treatment plant to serve Arequipa. In addition, an agreement was reached with the Peru government for development of a water storage network that was financed by Cerro Verde and a distribution network that was financed by the Cerro Verde Civil Association.

Cerro Verde constructed a wastewater treatment plant for the city of Arequipa, which was completed in 2015. The wastewater treatment plant supplements existing water supplies to support Cerro Verde's concentrator expansion and also improves the local water quality, enhances agriculture products grown in the area and reduces the risk of waterborne illnesses. In addition to these projects, Cerro Verde annually makes significant community development investments in the Arequipa region.

*Security Matters*. Consistent with our operating permits in Peru and our commitment to protect our employees and property, we have taken steps to provide a safe and secure working environment. As part of its security program, Cerro Verde maintains its own internal security department. Both employees and contractors perform functions such as protecting company facilities, monitoring shipments of supplies and products, assisting in traffic control and aiding in emergency response operations. The security department receives human rights and Voluntary Principles training annually. Cerro Verde's costs for its internal civilian security department totaled approximately $7 million in each of the years 2022, 2021 and 2020.

Cerro Verde, like all businesses and residents of Peru, relies on the Peru government for the maintenance of public order, upholding the rule of law and the protection of personnel and property. The Peru government is responsible for employing police personnel and directing their operations. Cerro Verde has limited public security forces in support of its operation, with the arrangement defined through an Inter-institutional Cooperation Agreement with the Peru National Police. Cerro Verde's share of support costs for government-provided security approximated $1 million in each of the years 2022, 2021 and 2020. Refer to Item 1A. "Risk Factors" for further discussion of security risks in Peru.

<u>Indonesia</u>. PT-FI provides funding and technical assistance to support various community development programs in areas such as health, education, economic development and local infrastructure. In 1996, PT-FI established a social investment fund with the aim of contributing to social and economic development in the Mimika Regency. Prior to 2019, the fund was mainly managed by the Amungme and Kamoro Community Development Organization, a community-led institution. In 2019, a new foundation, the Amungme and Kamoro Community Empowerment Foundation (Yayasan Pemberdayaan Masyarakat Amungme dan Kamoro, or YPMAK), was established, and in 2020, PT-FI appointed YPMAK to assist in distributing a significant portion of PT-FI's funding to support the development and empowerment of the local Indigenous Papuan people. YPMAK is governed by a Board of Governors consisting of seven representatives, including four from PT-FI.

------

In addition, since 2001, PT-FI has voluntarily established and contributed to land rights trust funds administered by Amungme and Kamoro representatives that focus on socioeconomic initiatives, human rights and environmental issues.

PT-FI is committed to the continued funding of YPMAK programs and the land rights trust funds, as well as for other local-community development initiatives through 2041 and has made and expects to continue making annual investments in public health, education, and local economic development. PT-FI recorded charges totaling $123 million in 2022, $109 million in 2021 and $67 million in 2020 to cost of sales for social and economic development programs.

*Security Matters*. Consistent with our ongoing commitment to protect our employees and property, we have taken steps to provide a safe and secure working environment. As part of its security program, PT-FI maintains its own internal civilian security department. Both employees and contractors perform functions such as protecting company facilities, monitoring shipments of supplies and products, assisting in traffic control and aiding in emergency response operations. The security department receives human rights training annually.

PT-FI's costs for its internal civilian security department totaled $50 million in both 2022 and 2021 and $47 million in 2020.

PT-FI, like all businesses and residents of Indonesia, relies on the Indonesia government for the maintenance of public order, upholding the rule of law and protection of personnel and property. The Grasberg minerals district has been designated by the Indonesia government as one of Indonesia's vital national assets. This designation results in the police, and to a lesser extent, the military, playing a significant role in protecting the area of our operations. The Indonesia government is responsible for employing police and military personnel and directing their operations.

From the outset of PT-FI's operations, the Indonesia government has looked to PT-FI to provide logistical and infrastructure support and assistance for these necessary services because of the limited resources of the Indonesia government and the remote location of and lack of development in Central Papua. PT-FI's financial support of the Indonesia government security institutions assigned to PT-FI's operations area represents a prudent response to PT-FI's requirements and commitments to protect its workforce and property better ensuring that personnel are properly fed and lodged and have the logistical resources to patrol PT-FI's roads and secure its area of operations. In addition, the provision of such support is consistent with our philosophy of responsible corporate citizenship, and reflects our commitment to pursue practices that protect and respect human rights.

PT-FI's support costs for the government-provided security totaled $25 million in both 2022 and 2021 and $22 million in 2020. This supplemental support consists of various infrastructure and other costs, including food, housing, fuel, travel, vehicle repairs, allowances to cover incidental and administrative costs, and community assistance programs conducted by the military and police. Refer to Item 1A. "Risk Factors" for further discussion of security risks in Indonesia.

**MINERAL RESERVES**

Our estimates of mineral reserves have been prepared using industry accepted practice and conform to the disclosure requirements of Subpart 1300 of SEC Regulation S-K. Proven and probable mineral reserves were determined from the application of relevant modifying factors to geological data to establish an operational, economically viable mine plan. The estimates are based on mapping, drilling, sampling, assaying and evaluation methods generally applied in the mining industry. Mineral reserves, as used in the mineral reserve data presented here, means the economically mineable part of a measured or indicated resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted. Proven mineral reserves mean the economically mineable part of a measured mineral resource, from geological evidence revealed in outcrops, trenches, workings or drill holes with grades and/or quality estimates from detailed, closely spaced sampling, and geologic characterization that defines the size, shape, depth and mineral content to a high degree of confidence. Probable mineral reserves means the economically mineable part of an indicated mineral resource, for which quantity and grade are estimated from information similar to that used for measured mineral resources where the samples are farther apart, and the geological characterization is adequate. Probable mineral reserves can also include remaining portions of a measured mineral resource. The degree of assurance, although lower than that for proven mineral reserves, is high enough to assume continuity between points of observation.

Our estimates of recoverable proven and probable mineral reserves are prepared by and are the responsibility of our employees. These estimates are reviewed and verified regularly by independent experts in mining, geology and reserve determination. Our mineral reserve estimates are based on the latest available geological and geotechnical studies. We conduct ongoing studies of our ore bodies to optimize economic values and to manage risk. We revise our mine plans and estimates of recoverable proven and probable mineral reserves as required in accordance with the latest available studies. Refer to Item 1A. "Risk Factors" for discussion of risks associated with our estimates of proven and probable mineral reserves.

Estimated recoverable proven and probable mineral reserves at December 31, 2022, were determined using metal price assumptions of $3.00 per pound for copper, $1,500 per ounce for gold and $12 per pound for molybdenum. For the three-year period ended December 31, 2022, LME copper settlement prices averaged $3.67 per pound, London PM gold prices averaged $1,789 per ounce and the weekly average price for molybdenum quoted by *Platts Metals Daily* averaged $14.44 per pound.

The estimated recoverable proven and probable mineral reserves presented in the table below represent the estimated metal quantities from which we expect to be paid after application of estimated metallurgical recoveries and smelter recoveries, where applicable.

In defining our open-pit mineral reserves, we apply an "operational cutoff grade" strategy, wherein multiple processing options, throughput constraints, mine development and ore availability are given consideration to maximize the value of our operations. In defining our open-pit mineral resources, internal cutoff grades are applied. The internal cutoff grade is defined for a metric ton of ore as that equivalent copper grade, once produced and sold, that generates sufficient revenue to cover estimated processing and administrative costs. We use "break-even cutoff grades" to define the in-situ mineral reserves and resources for our underground ore bodies. The break-even cutoff grade is defined for a metric ton of ore as that equivalent copper grade, once produced and sold, that generates sufficient revenue to cover all operating and administrative costs associated with our production.

Our copper mines may contain other commercially recoverable metals, such as gold, molybdenum and silver. We value all commercially recoverable metals in terms of a copper equivalent percentage to determine a single cutoff grade. Copper equivalent percentage is used to express the relative value of multi-metal ores in terms of one metal. The calculation expresses the relative value of the ore using estimates of contained metal quantities, metals prices as used for reserve or resource determination, recovery rates, treatment charges and royalties. Our molybdenum properties use a molybdenum cutoff grade.

**Production Sequencing** 

The following chart illustrates our current plans for sequencing and producing our proven and probable mineral reserves at each of our ore bodies and the years in which we currently expect production from each ore body and related stockpiles. Our proven and probable mineral reserves in Indonesia reflect estimates of minerals that can be recovered through the end of 2041, and our current mine plan and planned operations are based on the assumption that PT-FI will comply with its obligations under the IUPK and receive the second 10-year extension from 2031 through 2041 (refer to Item 1A. "Risk Factors" and Note 13 for further discussion). We develop our mine plans based on maximizing the net present value from the ore bodies. Significant additional capital expenditures will be required at many of these mines in order to achieve the life-of-mine plans reflected below.

![fcx-20221231_g15.jpg](fcx-20221231_g15.jpg)

a.Development commenced in October 2021. The ultimate timing of the start of production is dependent upon a number of factors and may vary from the date shown here.

**Mill and Leach Stockpiles** 

Mill and leach stockpiles generally contain lower grade ores that have been extracted from an ore body and are available for metal recovery. Mill stockpiles contain sulfide ores and recovery of metal is through milling, concentrating, smelting and refining or, alternatively, by concentrate leaching. Leach stockpiles contain oxide ores and certain secondary sulfide ores and recovery of metal is through exposure to acidic solutions that dissolve contained copper and deliver it in solution to extraction processing facilities.

Because it is impracticable to determine copper contained in mill and leach stockpiles by physical count, reasonable estimation methods are employed. The quantity of material delivered to mill and leach stockpiles is based on surveyed volumes of mined material and daily production records. Sampling and assaying of blasthole cuttings determine the estimated copper grades of material delivered to mill and leach stockpiles.

Expected copper recoveries for mill stockpiles are determined by metallurgical testing. The recoverable copper in mill stockpiles, once entered into the production process, can be produced into copper concentrate almost immediately.

Expected copper recoveries for leach stockpiles are determined using small-scale laboratory tests, small- to large-scale column testing (which simulates the production process), historical trends and other factors, including

------

mineralogy of the ore and rock type. Total copper recovery in leach stockpiles can vary significantly from a low percentage to more than 90% depending on several variables, including processing methodology, processing variables, mineralogy and particle size of the rock. For newly placed material on active stockpiles, as much as 80% of total copper recovery may be extracted during the first year, and the remaining copper may be recovered over many years. Processes and recoveries are monitored regularly, and recovery estimates are adjusted periodically as additional information becomes available and as related technology changes.

Following are our stockpiles and the estimated recoverable copper contained within those stockpiles as of December 31, 2022:

**Mineral Resources**

In addition to mineral reserves, our properties contain mineral resources that we believe could be brought into production should market conditions warrant. However, permitting and significant capital expenditures may be required before mining of these resources could commence at these properties. A mineral resource is a concentration or occurrence of material of economic interest in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. Such a deposit cannot qualify as recoverable proven and probable mineral reserves until engineering, legal and economic feasibility are confirmed based upon a comprehensive evaluation of development and operating costs, grades, recoveries and other material factors. Mineral resources include measured, indicated and inferred mineral classifications.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A measured mineral resource is a resource for which the quantity and grade are estimated from detailed, closely spaced sampling, and geologic characterization that defines the size, shape, depth and mineral content to a high degree of confidence.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An indicated mineral resource is a resource for which quantity and grade are estimated from information similar to that used for measured mineral resources where the samples are farther apart, and the geological characterization is adequate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An inferred mineral resource is a resource for which quantity and grade are estimated from information similar to that used for measured and indicated mineral resources, but with limited geological evidence and sampling. Inferred mineral resource grade and mineralization continuity have a lower degree of confidence.

Our estimates of mineral resources have been prepared in accordance with the disclosure requirements of Subpart 1300 of SEC Regulation S-K. No assurance can be given that the estimated mineral resources not included in mineral reserves will become proven and probable mineral reserves.

Estimated mineral resources as presented on the following pages were assessed using prices of $3.50 per pound for copper, $1,500 per ounce for gold, $15 per pound for molybdenum and $20 per ounce for silver. Cutoff grade strategy and expected recoveries used to evaluate mineral resources are consistent with those for mineral reserves but would require additional work to substantiate. Refer to Item 1A. "Risk Factors" for discussion of risks associated with our estimates of mineral resources.

a.Adjustments at Morenci and Cerro Verde are primarily the result of higher resource metal prices, partly offset by converting material from mineral resources to mineral reserves in revised mine designs. Adjustments at the Grasberg minerals district are primarily the result of the expansion of mineral resources below the reserve footprints.

**Internal Controls over the Mineral Reserves and Mineral Resources Estimation Process**

We have internal controls over the mineral reserves and mineral resources estimation processes that result in reasonable and reliable estimates aligned with industry practice and reporting regulations. Annually, qualified persons and other employees review the estimates of mineral reserves and mineral resources, the supporting documentation, and compliance with the internal controls and, based on their review of such information, recommend approval to use the mineral reserve and mineral resource estimates to our senior management. Our controls utilize management systems including but not limited to, formal quality assurance and quality control protocols, standardized procedures, workflow processes, supervision and management approval, internal and external reviews and audits, reconciliations, and data security covering record keeping, chain of custody and data storage.

Our systems cover exploration activities, sample preparation and analysis, data verification, mineral processing, metallurgical testing, recovery estimation, mine design and sequencing, and mineral reserve and resource evaluations, with environmental, social and regulatory considerations. Our quality assurance and control protocols over sampling and assaying of drill hole samples include insertion of blind samples consisting of standards, blanks, and duplicates in the primary sample streams, as well as selective sample validation at secondary laboratories.

These controls and other methods help to validate the reasonableness of the estimates. The effectiveness of the controls is reviewed periodically to address changes in conditions and the degree of compliance with policies and procedures. Refer to Item 1A. "Risk Factors" for discussion of risks associated with our estimates of mineral reserves and mineral resources.

**<u>Financial risks</u>**

***Fluctuations in the market prices of the commodities we produce have caused and may continue to cause significant volatility in our financial performance and in the trading prices of our common stock. Extended material declines in the market prices of such commodities could adversely affect our financial condition and operating plans.***

Our financial results vary with fluctuations in the market prices of the commodities we produce, primarily copper and gold, and to a lesser extent molybdenum. Extended material declines in market prices of such commodities could have a material adverse effect on our financial results and the value of our assets, may depress the price of our common stock, and may have a material adverse effect on our ability to comply with financial and other covenants in our debt agreements, service our debt and meet our other obligations. Beginning in 2020 with the onset of the COVID-19 pandemic and continuing in 2022 because of a series of macro-economic factors, there has been significant volatility in the financial and commodities markets, including the copper market. Copper prices reached a record high of $4.87 per pound in first-quarter 2022 but dropped to a 2022 low of $3.18 in third-quarter 2022. For

------

additional information regarding recent macro-economic factors, see risk factor below regarding the price and availability of consumables and components we purchase and constraints on supply and logistics, and transportation services.

Fluctuations in commodities prices are caused by varied and complex factors beyond our control, including global supply and demand and inventory levels; global economic and political conditions (such as a potential global recession and Russia's invasion of Ukraine); international regulatory, trade and/or tax policies, including national tariffs; commodities investment activity and speculation; interest rates; expectations regarding future inflation rates; the strength of the U.S. dollar compared to foreign currencies; the price and availability of substitute products; and changes in technology. Volatility in global economic growth, particularly in developing economies, has the potential to adversely affect future demand and prices for commodities. Geopolitical uncertainty and protectionism, have the potential to inhibit international trade and negatively impact business confidence, which creates the risk of constraints on our ability to trade in certain markets and has the potential to increase price volatility.

In addition to the factors discussed above, copper prices may be affected by demand from China, which is currently the largest consumer of refined copper in the world, including as a result of geopolitical uncertainty between the U.S. and China as well as uncertainties about China's economy, including its COVID-19 policies. The adoption and expansion of trade restrictions, changes in China-U.S. relations, or other governmental action related to tariffs or trade agreements or policies are difficult to predict and could adversely affect copper prices, demand for our products, our costs, our customers, our suppliers, and the U.S. economy, which in turn could have a material adverse effect on our business, results of operations or financial condition.

Copper prices also may be affected by the growing markets for automobiles and appliances, and the global focus on a transition to new technologies for clean energy, to advance communications and to enhance public health, inadequate investment in and limited production from copper mining operations in South America, as well as demand from North America, Europe, and Asian countries other than China. Additional factors affecting gold prices may include purchases and sales of gold by governments and central banks, demand from China and India, two of the world's largest consumers of gold, and global demand for jewelry containing gold. For additional information regarding the historical fluctuations of the prices of copper, gold and molybdenum, refer to "Markets" in MD&A.

If market prices for the primary commodities we produce were to decline and remain low for a sustained period of time, we may have to revise our operating plans, including curtailing or modifying our mining and processing operations, as we had to do in early 2020 in response to the global COVID-19 pandemic. We may be unable to decrease our costs in an amount sufficient to offset reductions in revenues, in which case we may incur losses, and those losses may be material.

Declines in prices of commodities we sell could also result in metals inventory adjustments and impairment charges for our long-lived assets. Refer to Note 4 for additional information regarding metals inventory adjustments recorded for the three years ended December 31, 2022.

***Fluctuations in the price and availability of consumables and components for key machines and equipment we purchase, and constraints on supply and logistics could affect our profitability and operating plans. Further, significant delays or increases in costs affecting transportation services may affect our business.***

Consumables and components for key machines and equipment we purchase are subject to price volatility caused by global economic factors that are beyond our control, including, but not limited to, supply chain disruptions, labor shortages, wage pressures, rising inflation and potential economic slowdown or recession, as well as fuel and energy costs (for example, the price of diesel), the impact of natural disasters, public health crises (such as COVID-19), geopolitical conflicts (such as the conflict in Ukraine), and foreign currency exchange rate fluctuations, and other matters that have or could impact the global economy.

Prices and availability of consumables used in our operations, such as natural gas, diesel, coal, ammonium nitrate, chemical reagents (including sulfuric acid), and steel-related products, and components impact the costs of production at our operations and the costs of development projects. These prices fluctuate and can be volatile. In 2022, we experienced price increases on certain consumables, including diesel fuel and coal, ammonium nitrate and sulfuric acid, grinding media and certain components. The cost increases have negatively impacted our operating results and further increases could have a material adverse effect on our results of operations and could result in material changes to our operating plans. Additional increases may occur in 2023 because of macroeconomic conditions discussed above, and such increases may be material.

------

Ensuring continuity of supply of such consumables to our operations is critical to our business. We also rely on the availability of components from suppliers for key machines and equipment, which may be impacted by competition demands as well as the availability of input materials in the creation of such equipment. A supplier's failure to supply consumables or components in a timely manner or to meet our quality, quantity, cost requirements or our technical specifications, or our inability to obtain alternative sources of consumables or components on a timely basis or on terms acceptable to us, could adversely affect our operations. In 2022, we experienced longer lead times and logistical constraints on delivery of certain consumables, including fuel, lubricants, ammonium nitrate, cobalt sulfate, acid mist suppressant and acid. While these delays and logistical constraints did not significantly impact our results in 2022, these issues may continue in 2023 and such logistical constraints and delays may become material. Further, delays and logistical constraints may occur as a result of violence, civil and religious strife, and activism, as described in the related risk factor below.

Our business depends on the inbound transportation of consumables and components we use and the outbound transportation of the commodities we produce by truck, rail and ocean freight. There continue to be global shipping and logistics challenges, which began during the COVID-19 pandemic. Any significant increase in the cost of the transportation of consumables or components, as a result of increases in fuel or labor costs, higher demand for logistics services, or otherwise, would adversely affect our results of operations. Additionally, if the transportation service providers fail to deliver consumables or components used in our operations to us or the commodities we produce to our customers in a timely manner or at all, such failure could adversely impact our ability to meet our production schedules, delay our projects and capital initiatives, negatively affect our customer relationships and have a material adverse effect on our financial position and results of operations.

***Our debt and other financial commitments may limit our financial and operating flexibility.***

At December 31, 2022, our total consolidated debt was $10.6 billion (see MD&A and Note 8) and our total consolidated cash and cash equivalents was $8.1 billion. We also have various other financial commitments, including reclamation and environmental obligations, take-or-pay contracts and leases. Although we have been successful in servicing debt in the past, refinancing our bank facilities and issuing new debt securities in capital markets transactions, there can be no assurance that we can continue to do so. In addition, we or our subsidiaries may incur additional debt in future periods or reduce our holdings of cash and cash equivalents in connection with funding existing operations, capital expenditures, dividends, share or debt repurchases, or in pursuing other business opportunities. For further information, see the risk factors below relating to mine closure and reclamation regulations and the increasing scrutiny and evolving expectations from stakeholders, including creditors, with respect to our ESG practices, performance and disclosures.

Our level of indebtedness and other financial commitments could have important consequences to our business, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Limiting our flexibility in planning for, or reacting to, changes in the industry in which we operate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Increasing our vulnerability to general adverse economic, industry and regulatory conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Limiting our ability to fund future working capital, capital expenditures, general corporate requirements and/or material contingencies, to engage in future development activities, or to otherwise realize the value of our assets and opportunities fully because of the need to dedicate a substantial portion of our cash flows from operations to payments on our debt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Requiring us to sell assets to reduce debt; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Placing us at a competitive disadvantage compared to our competitors that have less debt and/or fewer financial commitments.

Any failure to comply with the financial and/or other covenants in our debt agreements may result in an event of default that would allow the creditors to accelerate maturities of the related debt, which in turn may trigger cross-acceleration or cross-default provisions in other debt agreements. Our available cash and liquidity may not be sufficient to fully repay borrowings under our debt instruments that may be accelerated upon an event of default.

As of January 31, 2023, our senior unsecured debt was rated "Baa3" with a stable outlook by Moody's Investors Service, "BBB-" with a stable outlook by Fitch Ratings, and "BB+" with a stable outlook by Standard & Poor's. If we are unable to maintain our indebtedness and financial ratios at levels acceptable to these credit rating agencies, or should our business prospects deteriorate, our current credit ratings could be downgraded, which could adversely

------

affect the value of our outstanding securities and existing debt, our ability to obtain new financing on favorable terms and could increase our borrowing costs.

***Changes in or the failure to comply with the requirements of mine closure and reclamation regulations could have a material adverse effect on our business.***

We are required by U.S. federal and state laws and regulations to provide financial assurance sufficient to allow a third party to implement approved closure and reclamation plans for our mining properties if we are unable to do so. As of December 31, 2022, our financial assurance obligations totaled $1.5 billion for closure and reclamation/restoration costs of U.S. mining sites. Refer to Note 12 for additional information regarding our financial assurance obligations and Items 1. and 2. "Business and Properties" for a discussion of certain of such U.S. federal and state laws and regulations applicable to us. A substantial portion of our financial assurance obligations are satisfied by guarantees by us and certain of our subsidiaries. Our ability to continue to provide guarantees depends on state and other regulatory requirements, our financial performance and our financial condition. Other forms of assurance, such as letters of credit and surety bonds, are costly to provide and, depending on our financial condition and market conditions, may be difficult or impossible to obtain. Failure to provide or maintain the required financial assurance could result in the closure of the affected properties.

Plans and provisions for mine closure and remediation may change over time as a result of changes in stakeholder expectations, legislation, standards, and technical understanding and techniques, which may cause our actual costs of closure and remediation to be higher than estimated for environmental and asset retirement obligations (AROs) and could materially affect our financial position or results of operations. For example, our implementation of the Global Industry Standard for Tailings Management (the Tailings Standard) (discussed in Items 1. and 2. "Business and Properties" herein) has required changes and could require additional changes to our closure and reclamation plans or modifications to previously completed reclamation actions, although it is uncertain if these changes would result in material capital or operating cost increases. In addition, climate change could lead to changes in the physical risks posed to our operations, which could result in changes in our closure and reclamation plans to address such risks. Any modifications to our closure and reclamation plans that may be required to address physical climate risks may increase our financial assurance obligations and may materially increase the actual costs associated with implementing closure and reclamation at any or all of our active or inactive mine sites or smelter sites. Refer to Notes 1 and 12 for further discussion of our environmental obligations and AROs and see the risk factors below relating to the potential physical impacts of climate change and our related obligations as part of our commitment to implementing the Tailings Standard.

***Unanticipated litigation or negative developments in pending litigation or other contingencies could have a material adverse effect on our financial condition.***

We are, and may in the future become, involved in various legal proceedings and subject to other contingencies that have arisen or may arise in the ordinary course of our business or are associated with environmental matters, including those described in Note 12 and in Item 3. "Legal Proceedings". We are also involved periodically in other reviews, inquiries, investigations and other proceedings initiated by or involving government agencies, some of which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief. From time to time we are involved in disputes over the allocation of environmental remediation obligations at "Superfund" and other sites. In addition, we may be held responsible for the costs of addressing contamination at the site of current or former activities or at third party sites, or be held liable to third parties for exposure to hazardous substances should those be identified in the future. The outcome of litigation is inherently uncertain and adverse developments or outcomes can result in significant monetary damages, penalties, other sanctions or injunctive relief against us, limitations on our property rights, or regulatory interpretations that increase our operating costs. Management does not believe, based on currently available information, that the outcome of any individual legal proceeding will have a material adverse effect on our financial condition, although individual or cumulative outcomes could be material to our operating results for a particular period, depending on the nature and magnitude of the outcome and the operating results for the period.

Regardless of the merit of particular claims, defending against litigation or responding to investigations can be expensive, time-consuming, disruptive to our operations and distracting to management. In recognition of these considerations, we may enter into agreements or other arrangements to settle litigation and resolve such challenges. There can be no assurance such agreements can be obtained on acceptable terms or that litigation will not occur.

------

Further, we are a global business with operations in various jurisdictions. In the event of a dispute arising at our foreign operations, we may be subject to the exclusive jurisdiction of foreign courts or arbitral panels, or may not be successful in subjecting foreign persons to the jurisdiction of courts or arbitral panels in the U.S. or in enforcing the judgment of a foreign court or arbitral panel against a sovereign nation. Our inability to enforce our right and the enforcement of rights on a prejudicial basis by foreign courts or arbitral panels, including against a sovereign nation, could have an adverse effect on our results of operations and financial position.

***Changes in tax laws and regulations could have a material adverse effect on our financial condition.***

As a global business, we are subject to income, royalty, transaction and other taxes in the U.S. and various foreign jurisdictions. Uncertainties exist with respect to our tax liabilities, including those arising from changes in laws in the countries in which we do business. We have significant net operating losses (NOLs) in the U.S. generated in prior years. These NOLs are available to offset future regular taxable income, which we believe will result in minimal estimated regular income tax liability in the U.S. over the next several years at current metals market prices.

In August 2022, the U.S. Inflation Reduction Act of 2022 (the Act) was signed into law, which includes, among other provisions, a new Corporate Alternative Minimum Tax (CAMT) of 15% on the adjusted financial statement income (AFSI) of corporations with average AFSI exceeding $1.0 billion over a three-year period. The provisions of the Act are applicable to us beginning January 1, 2023. Additional guidance related to how the CAMT provisions of the Act will be applied or otherwise administered is yet to be released by the U.S. Department of the Treasury, and may differ from our interpretations. We will continue to analyze the impacts as additional guidance becomes available. We expect the CAMT provisions will impact our U.S. tax position, and may further limit our ability to benefit from our U.S. NOLs.

We are also continuing to monitor the progress of Chile's proposed mining royalty changes and their impact on future operations.

Further, recommendations from the Organization for Economic Co-operation and Development regarding a global minimum income tax and other changes being considered and/or implemented in countries where we operate could materially impact our provisions for income and non-income taxes, cash tax liability and effective tax rate.

**<u>International risks</u>**

***Our international operations are subject to geopolitical, economic and social risks.***

We are a U.S.-based mining company with substantial assets located outside of the U.S. Risks of conducting business in countries outside the U.S. can include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Delays in obtaining or renewing, or the inability to obtain, maintain or renew, or the renegotiation, cancellation, revocation or forced modification (including the inherent risk of these actions being taken unilaterally by government owned entities) of contracts, leases, licenses, permits, stability agreements or other agreements and/or approvals;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Expropriation or nationalization of property, protectionism, or restrictions on repatriation of earnings or capital;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Changes in and differing interpretations of the host country's laws, regulations and policies (which may be applied retroactively), including, but not limited to, those relating to labor, taxation, royalties, duties, tariffs, divestment, imports, exports (including restrictions on the export of copper concentrate and anode slimes, copper and/or gold), trade regulations, immigration, currency, human rights and environmental matters (including land use and water use), additional requirements on foreign operations and investment, and/or fines, fees and sanctions imposed for failure to comply with the laws and regulations of the jurisdictions in which we operate, the risk of any of which may increase with rising "resource nationalism" in countries around the world;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Geopolitical events, social and economic instability, bribery, extortion, corruption, civil unrest, blockades, acts of war, guerrilla activities, insurrection and terrorism, certain of which may result in, among other things, an inability to access our property or transport our commodities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Risk of loss associated with trespass, illegal artisanal mining, theft, sabotage and vandalism;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Changes in U.S. trade, tariff, tax, immigration or other policies that may impact relations with foreign countries or result in retaliatory policies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Increases in training and other costs and challenges relating to requirements by governmental entities to employ nationals of a country in which a particular operation is located;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Foreign exchange controls and fluctuations in foreign currency exchange rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reduced protection for intellectual property rights; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The risk of having to submit to the jurisdiction of an international court or arbitration panel or having to enforce the judgment of an international court or arbitration panel against a sovereign nation within its own territory.

Our insurance does not cover most losses caused by the risks described above. For example, we do not have political risk insurance. Accordingly, our exploration, development and production activities outside of the U.S. may be substantially affected by many external factors beyond our control, some of which could have a material adverse effect on our cash flows, results of operations and financial condition.

We are required to comply with a wide range of laws and regulations in the countries where we operate or do business. For example, our international operations must comply with the U.S. Foreign Corrupt Practices Act and similar anti-corruption and anti-bribery laws of the other jurisdictions in which we operate. We operate in jurisdictions that have experienced public and private sector corruption and where significant anti-corruption enforcement activities, prosecutions and settlements have occurred. We have a large number of contracts with local and foreign suppliers and contractors, who may take action contrary to or fail to adopt standards, controls and procedures, including health, safety, environment, human rights and community standards that are equivalent to our standards, controls and procedures. There can be no assurance that our internal control policies and procedures will always protect us from misinterpretation of or noncompliance with applicable laws and internal policies, recklessness, fraudulent behavior, dishonesty or other inappropriate acts committed by our affiliates, employees, agents, suppliers or contractors. As such, our corporate policies and processes may not prevent or detect all potential breaches of law or governance practices. Any breaches could result in safety events that may result in injuries or fatalities, significant criminal or civil fines and penalties, litigation or regulatory action or inquiries, shareholder activism (such as to stop using a certain supplier or contractor), civil unrest or other adverse impacts on human rights, and loss of operating licenses or permits, and may damage our reputation, which could have a material adverse effect on our cash flows, results of operations and financial condition.

We conduct international mining operations and exploration activities in Indonesia, Peru and Chile and other foreign jurisdictions. Accordingly, in addition to the usual risks associated with conducting business in countries outside the U.S., our business may be adversely affected by political, economic, social and regional uncertainties in each of these countries. For example, we are involved in several significant tax proceedings and other tax disputes with Indonesia and Peru tax authorities (refer to Note 12 for further discussion of these matters). Other risks specific to certain countries in which we operate are discussed in more detail below.

***Because our mining operations in Indonesia are a significant operating asset, our business may be adversely affected by political, economic and social uncertainties in Indonesia.***

Maintaining a good working relationship with the Indonesia government, PT Indonesia Asahan Aluminium (Persero) (PT Inalum, also known as MIND ID), an Indonesia state-owned enterprise and shareholder in PT-FI and the local population, is important because of the significance of our Indonesia operations to our business, and because our mining operations there are among Indonesia's most significant business enterprises. Partially because of the Grasberg minerals district's significance to Indonesia's economy, the environmentally sensitive area where it is located, and the number of people employed, our Indonesia operations have been the subject of political debates and criticism in the Indonesia press, and have been the target of protests and occasional violence. Improper management of our working relationship with the Indonesia government, MIND ID or the local population could lead to a disruption of operations and/or impact our reputation in Indonesia and in the region where we operate, which could adversely affect our business.

The mining industry is subject to extensive regulation within Indonesia, and there have been major developments in laws and regulations applicable to mining concession holders, some of which have conflicted with PT-FI's contractual rights in the past. In particular, the enactment of Law No. 4 of 2009 on Coal and Mineral Mining on January 12, 2009 (the Mining Law) replaced the previous regulatory framework which allowed concession holders,

------

including PT-FI, to conduct mining activities in Indonesia under a contract of work system. Notwithstanding provisions in PT-FI's former Contract of Work (COW) prohibiting it from doing so, the Indonesia government sought to modify PT-FI's former COW to address provisions contained in the Mining Law and implementing regulations adopted thereunder, some of which were not required under or conflicted with PT-FI's former COW.

In early 2017, the Indonesia government issued new regulations to address exports of unrefined metals, including copper concentrate and anode slimes, and other matters related to the mining sector. Copper concentrate sales to PT Smelting (PT-FI's 39.5% owned copper smelter and refinery located in Gresik, Indonesia) totaled over 10% of our consolidated revenues for each of the years ended December 31, 2022, 2021 and 2020. PT-FI's export license for copper concentrate is valid for one-year periods, subject to review by the Indonesia government every six months, depending on greenfield smelter construction progress. PT-FI's current export license remains valid through March 19, 2023. Refer to Note 12 for further discussion of the administrative fine paid by PT-FI to the Indonesia government in March 2022 for failing to achieve physical development progress on the greenfield smelter. The 2017 regulations also permit the export of anode slimes, which is necessary for PT Smelting to continue operating. PT Smelting's export license for anode slimes expires on November 3, 2023. As discussed in Note 3, beginning in January 2023, PT-FI's commercial arrangement with PT Smelting converted to a tolling arrangement, under which PT-FI pays PT Smelting a tolling fee to smelt and refine its concentrate and will retain title to all products for sales to third parties.

Notwithstanding PT-FI's rights to export copper concentrate through 2023 under its IUPK (subject to force majeure considerations), its current copper concentrate export license and PT Smelting's current anode slimes export license, PT-FI may not be able to obtain administrative approval for such exports if the Indonesia government bans exports of copper concentrate and anode slimes prior to completion of the greenfield smelter and precious metals refinery (PMR). Recent press reports have indicated that the Indonesia government is considering a ban of copper concentrate exports effective in June 2023 under regulations that were issued in 2020 and 2021. In addition, PT Smelting exports may also be restricted (contrary to the expiration date of PT Smelting's current export license noted above). If such limitations on exports were to be instituted prior to PT-FI's greenfield smelter and PMR becoming operational (currently expected in 2024), PT-FI would be required to reduce production levels or be subject to additional costs.

Further, even if the Indonesia government does not ban exports of copper concentrate or anode slimes, we cannot predict when and if PT-FI's copper concentrate export license and PT Smelting's anode slimes export license may be renewed. PT-FI's sales of copper concentrate and anode slimes could be interrupted if the export licenses are not timely renewed or if PT-FI or PT Smelting is unable to operate because of other operational or financial constraints, which would adversely impact our revenues and operations.

There can be no assurance that future regulatory changes affecting the mining industry in Indonesia will not be introduced or unexpectedly repealed, or that new interpretations of existing laws and regulations will not be issued, which could adversely affect our business, financial condition and results of operations.

In 2022, the Indonesia government divided the Indonesia portion of the island of New Guinea from two provinces into a total of six provinces, which has resulted in public protest and civil unrest. For further discussion of violence, civil and religious strife, and activism affecting our operations in Indonesia, see the related risk factor below. Further, we cannot predict the impact of splitting provinces on local and regional regulations, permits and other governmental administrative functions, which could have an adverse impact on our business.

In 2024, Indonesia will hold national legislative elections. The presidential election will be held in February 2024. Political considerations leading up to these elections could affect, among other things, the country's policies pertaining to foreign investment, permitting and export restrictions, which could adversely affect our Indonesia mining operations.

***PT-FI will not mine all of the ore reserves in the Grasberg minerals district before the initial term of its IUPK expires in 2031. PT-FI's IUPK may not be extended through 2041 if PT-FI fails to abide by its terms and conditions and applicable laws and regulations.***

On December 21, 2018, PT-FI was granted an IUPK to replace its former COW, enabling PT-FI to conduct operations in the Grasberg minerals district through 2041. Under the terms of the IUPK, PT-FI has been granted mining rights through 2031, with rights to extend its mining rights through 2041, subject to, among other things, PT-FI's completion of construction of additional domestic smelting capacity totaling 2 million dry metric tons of

------

concentrate per year by the end of 2023 (an extension of which has been requested because of COVID-19 mitigation measures, subject to the approval of the Indonesia government), and fulfilling its defined fiscal obligations to the Indonesia government. Refer to Note 13 for a summary of the IUPK's key fiscal terms. The expansion of PT Smelting is expected to be complete by the end of 2023 and the construction of the greenfield smelter is expected to be completed during 2024, which is subject to, among other things, no additional COVID-19 related disruptions.

The IUPK also requires PT-FI to pay duties on concentrate exports of 2.5% now that development progress for additional smelting capacity in Indonesia has exceeded 30%, which may be eliminated upon receiving verification and approval from the Indonesia government that development progress for additional smelting capacity in Indonesia has exceeded 50%. Refer to Note 12 for further discussion of the administrative fine paid by PT-FI to the Indonesia government for failing to achieve physical development progress on the greenfield smelter.

The current capital cost estimate for the greenfield smelter and related precious metal refinery approximates $3 billion (excluding capitalized interest, owner's costs and commissioning). Capital expenditures for the Indonesia smelter projects are being funded with proceeds from PT-FI's senior notes and its available revolving credit facility. PT-FI's ability to raise and service any additional sources of capital, if needed, would be a function of macroeconomic conditions, and future market prices as well as PT-FI's operational performance, cash flows and debt position, among other factors. Additional financing may not be available if and when needed or, if available, the terms of such financing may not be favorable to PT-FI. See the risk factor below regarding increasing scrutiny and evolving expectations from stakeholders, including creditors, with respect to our ESG practices, performance and disclosures.

Our proven and probable mineral reserves in Indonesia reflect estimates of minerals that can be recovered through the end of 2041, and PT-FI's current long-term mine plan and planned operations are based on the assumption that PT-FI will abide by the terms and conditions of the IUPK and will be granted the 10-year extension from 2031 through 2041. As a result, PT-FI will not mine all of these mineral reserves during the initial term of the IUPK. Prior to the end of 2031, we expect to mine 46% of aggregate proven and probable recoverable mineral reserves at December 31, 2022, representing approximately half of our net equity share of recoverable copper and gold reserves.

If PT-FI does not complete the construction of additional domestic smelting capacity totaling 2 million metric tons of concentrate per year by the end of 2023 (an extension of which has been requested because of COVID-19 mitigation measures, subject to the approval of the Indonesia government), or fulfill its defined fiscal obligations to the Indonesia government as set forth in the IUPK, the IUPK may not be extended from 2031 through 2041, and PT-FI would be unable to mine all of its proven and probable mineral reserves in the Grasberg minerals district, which would adversely affect our business, results of operations and financial position.

PT-FI and the Indonesia government have begun preliminary discussions regarding the extension of PT-FI's IUPK beyond 2041. We cannot predict whether PT-FI will be successful in the extension of its IUPK beyond 2041.

**<u>Operational risks</u>**

***Our mining operations are subject to operational risks that could adversely affect our business and our underground mining operations have higher risks than a surface mine.***

We have assets in a variety of geographic locations, all of which exist in and around broader communities and environments. Maintaining the operational integrity and performance of our assets is crucial to protect our people, the environment and communities in which we operate. Our mines are very large in scale and, by their nature are subject to significant operational risks, some of which are outside of our control, and many of which are not covered fully, or in some cases even partially, by insurance. These operational risks, which could materially and adversely affect our business, operating results and cash flows, include earthquakes, rainstorms, floods, wildfires and other natural disasters; environmental hazards, including discharge of metals, concentrates, pollutants or hazardous chemicals; surface or underground fires; equipment failures; accidents, including in connection with mining equipment, milling equipment or conveyor systems, transportation of chemicals, explosives or other materials and in the transportation of employees and other individuals to and from sites (including where these services are provided by third parties such as vehicle and aircraft transport); wall failures and rock slides in our open-pit mines, and structural collapses of our underground mines or tailings impoundments; underground water and ore management;

------

lower than expected ore grades or recovery rates; and seismic activity resulting from unexpected or difficult geological formations or conditions (whether in mineral or gaseous form).

For a discussion of risks specific to our tailings management, see the risk factor below relating to our management of waste rock and tailings.

We are facing continued geotechnical challenges because of the older age of some of our open-pit mines and a trend toward mining deeper pits and more complex deposits. There can be no assurance that unanticipated geotechnical and hydrological conditions may or may not occur, nor whether these conditions may lead to events such as landslides and pit wall failures, in the future or that such events will be detected in advance. Geotechnical instabilities can be difficult to predict and are often affected by risks and hazards outside of our control, such as seismic activity or severe weather, which may lead to floods, mudslides, pit-wall instability and possibly even slippage of material. In early 2019, our El Abra operation in Chile experienced heavy rainfall and electrical storms. As a result, our operating results for 2019 were impacted by a suspension of El Abra's crushed leach stacking operations for approximately 35 days. We cannot predict whether similar events will occur in the future or the extent to which any such event would affect this, or any of our other operations.

Our business is dependent upon our workforce being able to safely perform their jobs, including the potential for physical injuries or illness. Underground mining operations can be particularly dangerous, and in May 2013, a tragic accident, which resulted in 28 fatalities and 10 injuries, occurred at the Grasberg minerals district when the rock structure above the ceiling of an underground training facility collapsed. There can be no assurance that similar events will not occur in the future.

We experience mining induced seismic activity, including landslides, from time to time in the Grasberg minerals district. The mine site is also in an active seismic area and has experienced earth tremors from time to time. In addition to the usual risks encountered in the mining industry, our Indonesia mining operations involve additional risks given their location in steep mountainous terrain in a remote area of Indonesia. These conditions have required us to overcome special engineering difficulties and develop extensive infrastructure facilities. The area also receives extreme rainfall, which has led to periodic floods and mudslides. Since February 11, 2023, PT-FI's operations have been temporarily disrupted because of significant rainfall and landslides, which restricted access to infrastructure near its milling operations. Recovery activities are in progress to clear debris from the affected areas and PT-FI is in the process of gradually resuming operations. Operations are expected to be fully restored by the end of February 2023.

As a result of this disruption, we expect our first-quarter 2023 sales volumes to be lower than previously expected. If PT-FI is not able to resume operations as currently expected or on our anticipated timeline, our results of operations may be further impacted. We cannot predict whether additional occurrences of seismic activity, extreme rainfall or other unexpected geological activity will occur that could cause material schedule delays or additional revisions to PT-FI's mine plans, which could adversely affect our cash flows, results of operations and financial condition.

We maintain insurance at amounts we believe to be reasonable to cover some of these risks and hazards; however, our insurance may not sufficiently cover losses from certain natural or operating disasters. There can be no assurance that such insurance will continue to be available, maintained, or that it will be available at economically feasible premiums. We may elect to not purchase insurance for certain risks because of the high premium costs associated with insuring such risk or for various other reasons. We do not have coverage for certain environmental losses and other risks. The lack of, or insufficiency of, insurance coverage could adversely affect our cash flows and overall profitability.

The occurrence of one or more of these events in connection with our exploration activities and development of and production from mining operations may result in the death of, or personal injury to, our employees, other personnel or third parties, the loss of mining equipment, damage to or destruction of mineral properties or production facilities, significant repair costs, monetary losses, deferral or unanticipated fluctuations in production, extensive community disruption (including short- and long-term health and safety risks), loss of licenses, permits or necessary approvals to operate, loss of workforce confidence, loss of infrastructure and services, disruption to essential supplies or delivery of our products, environmental damage and potential legal liabilities, all of which may adversely affect our reputation, business, prospects, results of operations and financial position. Further, the impacts of any serious incidents that occur may also be amplified if we fail to respond timely or in an appropriate manner.

***Our management of waste rock and tailings are subject to significant environmental, safety and engineering challenges and risks that could adversely affect our business.***

The waste rock (including overburden) and tailings produced in our mining operations represent our largest volume of waste material. Managing the volume of waste rock and tailings presents significant environmental, safety and engineering challenges and risks primarily relating to structural stability, geochemistry, water quality and dust generation. Management of this waste is regulated in the jurisdictions where we operate and our programs are designed to comply with applicable national, state and local laws, permits and approved environmental impact studies.

We maintain large leach pads and tailings impoundments containing viscous material. Tailings impoundments include large embankments that must be engineered, constructed and monitored to ensure structural stability and avoid structural collapse. Our tailings impoundments in arid areas must have effective programs to suppress fugitive dust emissions, and we must effectively monitor, prevent and treat acid rock drainage at all of our operations. In Indonesia, we use a river transport system for tailings management, which presents other risks discussed in more detail in the risk factor below relating to the environmental challenges at our Indonesia mining operations.

As of January 31, 2023, subsidiaries of our company currently operate 15 active tailings storage facilities (13 in the U.S. and 2 in Peru), of which 10 have an upstream design and 5 have a centerline design. We also manage 48 tailings storage facilities in the U.S. that are inactive or closed (41 with an upstream design, 5 with a centerline design and 2 with a downstream design) and another 9 with an upstream design that are deemed "safely closed" according to the definition in the Tailings Standard. In 2022, we produced approximately 331 million metric tons of tailings. The failure of tailings storage facilities and other embankments at any of our mining operations could cause severe, and in some cases catastrophic, property and environmental damage and loss of life, as well as adverse effects on our business and reputation. Some of our tailings storage facilities are located in areas where a failure has the potential to impact individual dwellings and a limited number of impoundments are in areas where a failure has the potential to impact nearby communities or mining infrastructure. There can be no assurance that a severe or catastrophic failure of any of our facilities will not occur in the future. For additional information regarding the company's tailings management and stewardship program, including the Tailings Standard, refer to Items 1. and 2. "Business and Properties" herein.

In addition, as part of our commitment to enhancing our resilience to climate change risks as well as our commitment to implement the Tailings Standard, we will be required to consider uncertainties as a result of climate change, incorporate that assessment into the relevant knowledge base for our tailings facilities, use this knowledge base to enhance the resilience of our approach to the impacts of climate change using an adaptive management approach, incorporate that knowledge into facility operations, and take measures to mitigate both environmental impact and potential failure risks at our active and inactive tailings facilities, including those arising from climate change. These obligations will likely require future changes at our tailings facilities, which could increase our operational expenses or require further capital investments. For further discussion of potential physical impacts of climate change see the related risk factor below.

Based on observations from tailings failures at unaffiliated mines, in addition to fatalities and severe personal, property and environmental damages, these events could result in limited or restricted access to mine sites, suspension of operations, decrease in mineral reserves, legal liability, government investigations, additional regulations and restrictions on mining operations in response to any such failure, increased monitoring costs and production costs, increased insurance costs or inability to obtain insurance, increased costs and/or limited access to capital, remediation costs, inability to comply with any additional safety requirements or obtain necessary certifications, evacuation or relocation of communities or other emergency action, and other impacts, which could have a material adverse effect on our operations and financial position.

***Our Indonesia mining operations are susceptible to difficult and costly environmental challenges, and future changes in Indonesia environmental laws could increase our costs.***

Mining operations on the scale of our Indonesia operations involve significant environmental risks and challenges. Our primary challenge is to dispose of the large amount of tailings. In 2022, PT-FI produced approximately 67 million metric tons of tailings. Our tailings management plan, which has been approved by the Indonesia government, uses an unnavigable river in the highlands to transport the tailings from the mill to an engineered tailings management area in the lowlands. Levees have been constructed along both sides of the lowlands tailings

------

management area to act as containment structures to laterally contain the footprint of the tailings deposition within the approved tailings management area.

Another major environmental challenge at PT-FI is managing overburden, which is rock that was required to be moved aside in the open pit mining process to reach the ore in the Grasberg open pit. In the presence of air, water and naturally occurring bacteria, some overburden can generate acid rock drainage, or acidic water containing dissolved metals that, if not properly managed, can adversely affect the environment. In addition, the Grasberg overburden stockpiles have experienced erosion over time, caused by the large amounts of rainfall, with the eroded stockpile material eventually entering into the lowlands tailings management area. This eroded overburden affects the volume as well as the physical and chemical characteristics of the sediment material deposited in the lowlands tailings management area, which can result in environmental impacts. PT-FI's current tailings deposition management plan as well as robust environmental monitoring programs take into account the presence of this overburden in the lowlands tailings management area.

As part of its ongoing management and monitoring program, PT-FI expanded the scope of its monitoring and analyses used to assess possible impacts to the environment and human health from overburden erosion and tailings, including conducting and updating a human health risk assessment. During 2022, PT-FI continued routine assessment of surface waters, groundwaters, sediments and soils, dust and terrestrial and aquatic tissues. Furthermore, PT-FI has been assisting local health authorities with an extensive regency-wide community health survey, which is providing further data on community health issues, including any potential impacts from operations. The ongoing community health work will assist in determining what additional monitoring and mitigation efforts may be required in the future.

In the past, the Indonesia government has raised questions with respect to our tailings and overburden management plans, including a suggestion that we implement a tailings pipeline and dam rather than the river transport system for tailings management. Our Indonesia mining operations are remotely located in steep mountainous terrain and in an active seismic area, which also experiences extreme weather events; such that, the pipeline infrastructure required to convey the volume of material is not feasible, and would be more prone to failure, and could therefore involve significant potentially adverse environmental issues. Based on our own studies and others conducted by third parties, we believe that our controlled riverine transport system is the best site-specific option for tailings management at the Indonesia site.

Overtopping or failure of any tailings containment structures (levees or protection structures) induced by extreme weather events such as floods, a major seismic event or naturally-occurring weak ground under the structures, are potential risks. The potential impacts from any such occurrence could vary significantly depending upon the specific location of the failure. Unanticipated structural failure of these structures in certain areas in the future could result in flooding of the nearby communities and related loss of lives and/or severe personal, property and environmental damages. Under certain conditions, a failure may necessitate evacuation or relocation of communities or other emergency action, financial assistance to the communities impacted, and remediation costs to repair and compensate for the social, cultural and economic impacts.

In addition, in the southern portion of the approved tailings management area, tailings have the potential to create depositional impacts outside of the approved boundary unless the protection structures (as proposed by PT-FI) are extended. An extension of these protection structures is planned and is currently awaiting permitting, which continues to progress. If the permitting for these protection structures is not received in a timely manner, or not received at all, there is a risk that the tailings in the lower portion of the tailings management area could create depositional impacts outside of our approved footprint and potentially impact the environment and communities. Refer to Items 1. and 2. "Business and Properties" for further discussion of our environmental obligations in Indonesia.

Managing these environmental challenges at our Indonesia operations could result in reputational harm and increased costs that could be significant.

There can be no assurance that future environmental changes affecting the mining industry in Indonesia will not be introduced or unexpectedly altered or repealed, or that new interpretations of existing Indonesia environmental laws and regulations will not be issued, which could have a significant impact on PT-FI.

***Violence, civil and religious strife, and activism could result in loss of life and disrupt our operations.***

Indonesia has long faced separatist movements and civil and religious strife in a number of provinces. Several separatist groups have sought increased political independence for the province of Central Papua, where our Grasberg minerals district is located. In Central Papua, there have been attacks on civilians by separatists and conflicts between separatists and the Indonesia military and police. In addition, illegal artisanal miners have clashed with police who have attempted to move them away from our facilities. Social, economic and political instability in Central Papua could materially and adversely affect us if it results in damage to our property or interruption of our Indonesia operations.

Starting in 2009, shooting incidents have occurred within the PT-FI project area, including along the road leading to our mining and milling operations, and there have been 22 fatalities and more than 75 injuries to our employees, contractor employees, government security personnel and civilians. There were several shooting incidents in the first half of 2020, including an incident near a PT-FI office building where one employee was killed and two others injured. In January 2021, a helicopter contracted to PT-FI was fired upon and struck by a single gunshot in an area adjacent to the project area. In 2022, outside of the PT-FI operational area but within the province of Central Papua, there were at least 30 incidents of separatist violence, resulting in 29 fatalities. Separatist security incidents, including shootings, continue to occur in Central Papua. PT-FI actively monitors security conditions and the occurrence of incidents both within the project area and regionally.

The safety of our workforce is a critical concern, and PT-FI continues to work with the Indonesia government to enhance security and address security-related issues within the PT-FI project area and in nearby areas. Although we have implemented measures and safeguards consistent with both international standards and our own internal standards relating to the use of force and respect for human rights, the implementation of these measures and safeguards does not guarantee that personnel, national police or other security forces will uphold these standards in every instance. We continue to limit the use of the road leading to PT-FI's mining and milling operations to secured convoys, including transport of personnel by armored vehicles in designated areas.

We cannot predict whether additional incidents will occur that could result in loss of life, or disruption or suspension of PT-FI's operations. If other disruptive incidents occur, they could adversely affect our results of operations and financial condition in ways that we cannot predict at this time.

South America countries have historically experienced uneven periods of economic growth, as well as recession, periods of high inflation and general economic and political instability. Since 2019, both Peru and Chile have experienced significant civil unrest unrelated to our operations. For example, in 2022, an unaffiliated copper producer in southern Peru repeatedly curtailed or suspended operations because of repeated and sustained community protests on the government-designated concentrate transport route along public roads, which have constrained such producer and at times other local producers from shipping their products. Such protests are ongoing. Other operations in the region have encountered significant issues with trespassers, illegal artisanal miners, and civil demonstrations that impact their current operations, expansion projects, logistical supply and product transport. Such protests have occasionally been accompanied by acts of violence and property damage, and continue intermittently in the region.

Although such civil unrest has not significantly impacted our results, similar events in the future could cause our South America operations to be materially impacted, in which case, we may not be able to meet our production and sales targets. Political uncertainty has created potential instability in the regulatory environment in Peru. In December 2022, Peru's congress impeached President Castillo, who was subsequently taken into custody by Peruvian authorities, and Vice President Boluarte was sworn in as president. Following these events, there have been widespread and sometimes violent political protests, including attacks on civil infrastructure and businesses, which have resulted in delays in the transport of supplies, products and people at our Cerro Verde mine. Other mining operations in the region have temporarily halted mining activities as a result of the civil unrest. A national state of emergency has been declared, and military forces deployed to augment national police, which have resulted in civilian and police fatalities. Although there has been a limited impact on Cerro Verde's operations, the situation in Peru remains uncertain, and a prolonged disruption of logistics and supply chains could impact future operations. In Chile, despite the overwhelming electoral approval of a proposal to rewrite the constitution in a 2020 referendum, the product of the constitutional assembly was rejected by over 60% of voters in 2022. While support for constitutional reform remains strong, uncertainty in the resolution of constitutional reform may contribute to incidents of social unrest. We cannot predict whether similar or more significant incidents of civil unrest or political instability will occur in the future in Peru or Chile.

***Our mining operations, including future expansions or developments, depend on the availability of significant quantities of secure water supplies.***

We recognize that access to clean, safe and reliable water supplies is vital to the health and livelihood of our host communities. Our mining operations require physical availability and secure legal rights to significant quantities of water, and the increasing pressure on water resources requires us to consider both current and future conditions in our approach. We aim to balance our operational water requirements with those of the local communities, environment and ecosystems. Most of our North America and South America mining operations are in areas where competition for water supplies is significant, and where climate change may lead to increasing scarcity of water resources in the future. Continuous production at our mines and any future expansions or developments are dependent on many factors, including our ability to maintain our water rights and claims, and the continuing physical availability of the water supplies. Current and long-term water risks include those that arise from our operations and events that we do not control (such as extreme weather and other physical risks associated with climate change). For further discussion of the potential physical impacts of climate change, see the related risk factor below.

As discussed in Item 3. "Legal Proceedings," in Arizona, where our operations use both surface water and groundwater, we are a participant in an active adjudication in which Arizona courts have been attempting, for over 45 years, to quantify and prioritize surface water claims for the Gila River watershed, one of the state's largest river systems. If we are not able to satisfactorily resolve the issues being addressed in the adjudications, water uses could be diminished or curtailed, and our operations at Morenci, Safford and Sierrita could be adversely affected unless we are able to acquire alternative resources.

Water for our Cerro Verde operation in Peru comes from renewable sources through a series of storage reservoirs on the Rio Chili watershed that collects water primarily from seasonal precipitation and from wastewater collected from the city of Arequipa and treated at a wastewater treatment plant constructed by us. As a result of occasional drought conditions, temporary supply shortages that could affect our Cerro Verde operation are possible.

Water for our El Abra mining operation in Chile comes from the continued pumping of groundwater from the Salar de Ascotán aquifer. In 2010, El Abra obtained regulatory approval for the continued pumping of groundwater from the Salar de Ascotán aquifer for its sulfide processing plant, which began operations in 2011. Our current permit will expire in 2029. The agreement to pump from this aquifer is subject to continued monitoring through 2029 of the aquifer water levels and select flora species to ensure that environmentally sensitive areas are not impacted by our pumping. If impact occurs, reductions in pumping are required to restore water levels, which could have an adverse effect on production from El Abra. For further discussion, see the risk factor above relating to the geopolitical, economic and social risks associated with our international operations.

Although we typically have sufficient water for our Indonesia operations, the area receives considerable rainfall that makes us susceptible to periodic floods and mudslides, the nature and magnitude of which cannot be predicted. For further discussion of the overburden and related environmental challenges, including as a result of flooding in Indonesia, see the related risk factor above.

Although each of our mining operations currently has access to sufficient water supplies to support current operational demands, as discussed above, the availability of additional supplies for potential future expansions or development will require additional investments and will take time to develop, if available. While we are taking actions to acquire additional back-up water supplies, such supplies may not be available at acceptable cost, or at all, so that the loss of a water right or currently available water supply could force us to curtail operations or force premature closures, and the ability to obtain future water supplies could prevent future expansions or developments, thereby increasing and/or accelerating costs or foregoing profitable operations.

***Major public health crises, including the COVID-19 pandemic, may have an adverse impact on our business.***

Pandemics, epidemics, widespread illness or other health crises, such as the COVID-19 pandemic (including any new variants), that interfere with the ability of our employees, suppliers, customers, financing sources or others to conduct business have and could adversely affect the global economy and our operations and business, including demand for the commodities we produce and our profit margins. For further information, see the risk factor above regarding fluctuations in market prices of the commodities we produce and the risk factor below regarding the prices and availability of the consumables and components we purchase and constraints on supply and logistics.

------

Actions taken by governmental authorities and third parties to contain and mitigate the risk of spread of any major public health crisis, including COVID-19, may negatively impact our business, including a disruption of or change to our operating plans. For example, in mid-March 2020, we had to temporarily transition our Cerro Verde mine to care and maintenance status and adjust operations to prioritize critical activities in response to a decree issued by the Peru government relating to COVID-19.

Our business and results of operations could be adversely affected if significant portions of our workforce are unable to work effectively, including because of illness, quarantines, government actions or other restrictions, or if workplace entry and travel are restricted resulting in the delay of key personnel or external consultants accessing our sites. There can be no assurance that our actions in response would be effective in containing and mitigating the risk of spread or a major outbreak of any public health crisis (including COVID-19) at our operating sites. A major health crisis at any of our operating sites, and particularly at PT-FI's remote operating site, could disrupt or change our operating plans, which may have a material adverse effect on our business and results of operations.

***Our information technology systems may be adversely affected by disruptions, damage, failure and risks associated with implementation and integration.***

Our industry has become increasingly supported by and dependent on digital technologies. Our strategy of operating large, long-lived, geographically diverse assets has been increasingly dependent on our ability to become fully integrated and highly automated. Many of our business and operational processes are heavily dependent on traditional and emerging technology systems to conduct day-to-day operations, improve safety and efficiency, and lower costs.

As our dependence on information systems, including those of our third-party service providers and vendors, grows, we become more vulnerable to an increasing threat of continually evolving cybersecurity risks. In recent years, cybersecurity events have increased in frequency and magnitude. These incidents may include, but are not limited to, installation of malicious software, phishing, ransomware, credential attacks, unauthorized access to data and other advanced and sophisticated cybersecurity breaches and threats, including threats that increasingly target critical operational technologies and process control networks. If any of these threats materialize, we could be subject to manipulation or improper use of our systems and networks, production downtimes, communication interruption or other disruptions and delays to our operations or to the transportation of products or infrastructure utilized by our operations, unauthorized release of proprietary, commercially sensitive, confidential or otherwise protected information, a misappropriation or loss of funds, the corruption of data, significant health and safety consequences, environmental damage, loss of intellectual property, fines and litigation, damage to our reputation or financial losses from remedial actions, any of which could have a material adverse effect on our cash flows, results of operations and financial condition. We have experienced targeted and non-targeted cybersecurity events in the past and may experience them in the future. While these cybersecurity events did not result in any material loss to us or interrupt our day-to-day operations, as of January 31, 2023, there can be no assurance that we will not experience any such losses or interruption in the future. Given the unpredictability of the timing and the evolving nature and scope of information technology disruptions, the various procedures and controls we use to monitor and protect against these threats and to mitigate our potential risks to such threats may not be sufficient in preventing cybersecurity events from materializing. Further, as cybersecurity threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate vulnerabilities to cybersecurity threats.

We could also be adversely affected by system or network disruptions if new or upgraded information technology systems are defective, not installed properly or not properly integrated into our operations. System modification failures could have a material adverse effect on our business, financial position and results of operations and could, if not successfully implemented, adversely impact the effectiveness of our internal controls over financial reporting.

Further, we increasingly depend on our information technology infrastructure for electronic communications among our locations, personnel, customers and suppliers around the world, including as a result of remote working and flexible working arrangements. These information technology systems, some of which are managed by third parties that we do not control, may be susceptible to damage, disruptions or shutdowns because of failures during the process of upgrading or replacing software, databases or components thereof, cutover activities in our restructuring and simplification initiatives, power outages, hardware failures, telecommunication failures, user errors, catastrophic events or other problems.

------

**<u>Human capital risks</u>**

***Labor disputes or labor unrest could disrupt our operations.***

Our business is dependent on maintaining good relations with our workforce. A significant portion of our employees are represented by labor unions in a number of countries under various collective bargaining agreements with varying durations and expiration dates. Refer to Items 1. and 2. "Business and Properties" of this annual report on Form 10-K for additional information regarding labor matters, and expiration dates of such agreements. As of December 31, 2022, approximately 30% of our global labor force was covered by collective bargaining agreements and approximately 2% of our global labor force was covered by agreements that will or were scheduled to expire during 2023 or that had expired as of December 31, 2022, and continue to be negotiated.

Labor agreements are negotiated on a periodic basis, and may not be renewed on reasonably satisfactory terms to us or at all. If we do not successfully negotiate new collective bargaining agreements with our union workers, we may incur prolonged strikes and other work stoppages at our mining operations, which could adversely affect our financial condition and results of operations. Additionally, if we enter into a new labor agreement with any union that significantly increases our labor costs relative to our competitors, our ability to compete may be materially and adversely affected.

We have in the past and could in the future experience labor disruptions such as work stoppages, work slowdowns, union organizing campaigns, strikes, or lockouts that could adversely affect our operations. For example, in third-quarter 2020, we experienced a five-day labor-related work stoppage related to COVID-19 travel restrictions when a small group of workers at PT-FI staged protests and a blockade restricting access to the main road to the mining operations area. We reached an amicable resolution with the group of workers while upholding our COVID-19 safety protocols. There were no strikes or lockouts at any of our operations in 2021 or 2022.

We cannot predict whether additional labor disruptions will occur. Significant reductions in productivity or protracted work stoppages at one or more of our operations could significantly reduce our production and sales volumes or disrupt operations, which could adversely affect our cash flows, results of operations and financial condition.

***Our success depends on our ability to recruit, retain, develop and advance qualified personnel.***

Our success is dependent on the contributions of our highly skilled and experienced workforce. Our business depends on our ability to recruit, retain, develop and advance a qualified, inclusive and diverse workforce at all levels. Our ability to recruit qualified personnel is affected by the available pool of workers with the training and skills necessary to fill the available positions, the impact on the labor supply because of general economic conditions and our ability to offer competitive compensation and benefit packages. Beginning in 2021 and during 2022, we experienced an increasingly competitive labor market and labor shortages at our North America operations. As a result of this labor shortage, we hired more contract workers in 2022, which increased our costs. If we fail to recruit, retain, develop and advance qualified, inclusive and diverse personnel necessary for the efficient operation of our business, this could result in decreased profitability, productivity and efficiency, safety performance challenges, and the delay of current and potential development projects, any of which may have a material adverse effect on our performance.

**<u>Risks related to development projects and mineral reserves</u>**

***Development projects are inherently risky and may require more capital and have lower economic returns than anticipated, and the operation and development of our underground mines are also subject to other unique risks.***

Mine development projects typically require a number of years and significant expenditures during the development phase before production is possible. There are many risks and uncertainties inherent in all development projects including, but not limited to, unexpected or difficult geological formations or conditions, potential delays (including the ability and timeframe to obtain permits, or because of weather, social or political unrest and major public health crisis), cost overruns, availability of economic sources and reliable access to water, power and infrastructure, lower levels of production during ramp-up periods, shortages of material or labor, construction defects, equipment breakdowns and injuries to persons and property.

------

All of our copper and gold production in Indonesia comes from underground mining in the Grasberg minerals district. The operation and development of our underground mines is also subject to other unique risks including, but not limited to, underground fires or floods, ventilating harmful gases, fall-of-ground accidents, and seismic activity resulting from unexpected or difficult geological formations or conditions. For example, we experience mining induced seismic activity from time to time in the Grasberg minerals district. While we anticipate taking all measures that we deem reasonable and prudent in connection with the development of our underground mines to safely manage production, there can be no assurance that these risks will not cause schedule delays, revised mine plans, injuries to persons and property, or increased capital costs, any of which may have a material adverse impact on our cash flows, results of operations and financial condition. Additionally, although we devote significant time and resources to our project planning, approval and review processes, many of our development projects are highly complex and rely on factors that are outside of our control, which may cause the actual time and capital required to complete a development project to exceed our estimates.

***Exploration is highly speculative, and our exploration activities may not result in additional discoveries to replace mineral reserves.***

Our existing mineral reserves will be depleted over time by production from our operations. Because our profits are primarily derived from our mining operations, our ability to replenish our mineral reserves is essential to our long-term success. Depleted mineral reserves can be replaced in several ways, including expanding known ore bodies, reducing operating costs that could extend the life of a mine by allowing us to cost-effectively process ore types that were previously considered uneconomic, by locating new deposits or acquiring interests in mineral reserves from third parties. Exploration is highly speculative in nature, involves many risks and uncertainties, requires substantial capital expenditures and, in some instances, advances in processing technology, and is frequently unsuccessful in discovering significant mineral resources since new, large, long-life deposits are increasingly scarce. Accordingly, our current or future exploration programs may not result in the discovery of additional deposits that can be produced profitably. Even if significant mineral resources are discovered, it will likely take many years from the initial phases of exploration until commencement of production, during which time the economic feasibility of production may change. We may not be able to discover, enhance, develop or acquire mineral reserves in sufficient quantities to maintain or grow our current reserve levels, which could negatively affect our cash flows, results of operations and financial condition.

***Estimates of mineral reserves and mineral resources are uncertain and the volume and grade of ore actually recovered may vary from our estimates.***

Our estimates of mineral reserves and mineral resources have been prepared in accordance with the disclosure requirements of Subpart 1300 of U.S. Securities and Exchange Commission (SEC) Regulation S-K. There are numerous uncertainties inherent in mineral estimates. Such estimates are, to a large extent, based on assumed long-term prices for the commodities we produce, primarily copper, gold and molybdenum, and interpretations of geologic data obtained from drill holes and other exploration techniques, which may not necessarily be indicative of future results. Our mineral estimates are based on the latest available geological and geotechnical studies. We conduct ongoing studies of our ore bodies to optimize economic values and to manage risk. We revise our mine plans and estimates of recoverable proven and probable mineral reserves as required in accordance with the latest available studies. Geological assumptions about our mineral resources that are valid at the time of estimation may change significantly when new information becomes available.

Estimates of mineral reserves, or the cost at which we anticipate the mineral reserves will be recovered, are based on assumptions, such as metal prices and other economic inputs. Changes to such assumptions may require revisions to mineral reserve estimates which could affect our asset carrying values and may also negatively impact our future financial condition and results. Until mineral reserves are actually mined and processed, the quantity of ore and grades must be considered as an estimate only.

In addition, if the market prices for the commodities we produce decline from assumed levels, if production costs increase or recovery rates decrease, or if applicable laws and regulations are adversely changed, there can be no assurance that the indicated level of recovery will be realized or that mineral reserves can be mined or processed profitably. If we determine that certain of our estimated recoverable proven and probable mineral reserves have become uneconomic, this may ultimately lead to a reduction in our aggregate reported mineral reserves, which could have a material adverse effect on our business, financial condition and results of operations.

------

Additionally, the term "mineral resources" does not indicate recoverable proven and probable mineral reserves as defined by the SEC. Estimates of mineral resources are subject to further exploration and evaluation of development and operating costs, grades, recoveries and other material factors, and, therefore, are subject to considerable uncertainty. Mineral resources do not meet the threshold for mineral reserve modifying factors, such as engineering, legal and/or economic feasibility, that would allow for the conversion to mineral reserves. Accordingly, there can be no assurance that the estimated mineral resources not included in mineral reserves will become recoverable proven and probable mineral reserves.

**<u>Regulatory, environmental and social risks</u>**

***The costs of compliance with environmental, health and safety laws and regulations applicable to our operations may constrain existing operations or expansion opportunities. Related permit and other approval requirements may delay or result in a suspension of our operations.***

Our operations are subject to extensive and complex laws and regulations, including environmental laws and regulations governing the generation, storage, treatment, transportation and disposal of hazardous substances; solid waste disposal; air emissions; wastewater discharges; remediation, restoration and reclamation of environmental contamination, including mine closures and reclamation; protection of endangered and threatened species and designation of critical habitats; and other related matters. These laws and regulations are subject to change and to changing interpretation by governmental agencies and other bodies vested with broad supervisory authority. As a mining company, compliance with environmental, health and safety laws and regulations is an integral and costly part of our business. In addition, we must obtain regulatory permits and approvals to start, continue and expand operations.

Certain federal and similar state laws and regulations may expose us to joint and several liability for environmental damages caused by our operations, or by previous owners or operators of properties we acquired or are currently operating or at sites where we previously sent materials for processing, recycling or disposal. As discussed in more detail in the risk factor below relating to costs incurred for remediating environmental conditions on our properties that are no longer in operation, we have substantial obligations for environmental remediation on properties previously owned or operated by Freeport Minerals Corporation (FMC) and certain of its affiliates. Noncompliance with these laws and regulations could result in material penalties or other liabilities. In addition, compliance with these laws may from time to time result in delays in or changes to our development or expansion plans. Compliance with these laws and regulations imposes substantial costs, which we expect will continue to increase over time because of increased regulatory oversight, adoption of increasingly stringent environmental standards, and other factors.

New or revised environmental regulatory requirements are frequently proposed, many of which have resulted and may in the future result in substantially increased costs for our business, including those regarding financial obligations. Regulations have been considered at various governmental levels to increase financial responsibility requirements for mine closure and reclamation. Adoption of such environmental regulations or more stringent application of existing regulations may materially increase our costs, threaten certain operating activities and constrain our expansion opportunities. In addition, there can be no assurance that restrictions relating to conservation will not have an adverse impact on expansion of our operations or not result in delays in project development, or constraints on exploration or operations in impacted areas.

We have incurred and expect to incur environmental capital expenditures and other environmental costs (including our joint venture partners' shares) to comply with applicable environmental laws and regulations that affect our operations. The timing and amounts of estimated payments could change as a result of changes in regulatory requirements, changes in scope and costs of reclamation activities, the settlement of environmental matters and the rate at which actual spending occurs on continuing matters.

We are also subject to extensive regulation of worker health and safety. Our mines are inspected on a regular basis by government regulators who may issue citations and orders when they believe a violation has occurred under applicable mining regulations. If inspections result in an alleged violation, we may be subject to fines and penalties and, in instances of alleged significant violations, our mining operations or industrial facilities could be subject to temporary or extended closures.

Many other governmental bodies regulate other aspects of our operations, and our failure to comply with these legal requirements can result in substantial penalties. In addition, new laws and regulations, including executive orders,

------

or changes to or new interpretations of existing laws and regulations by courts or regulatory authorities occur regularly, but are difficult to predict. Any such variations could negatively impact the mining sector, including our business, substantially increase costs to achieve compliance or otherwise could have a material adverse effect on our cash flows, results of operations and financial condition.

For additional information regarding the various regulations affecting us, see Items 1. and 2. "Business and Properties" of this annual report on Form 10-K.

***We incur significant costs for remediating environmental conditions on properties that have not been operated in many years.***

FMC and its subsidiaries, and many of their affiliates and predecessor companies, have been involved in exploration, mining, milling, smelting and manufacturing in the U.S. for more than a century. Activities that occurred in the late 19th century and the 20th century prior to the advent of modern environmental laws were not subject to environmental regulation and were conducted before U.S. industrial companies fully understood the long-term effects of their operations on the surrounding environment.

Companies like FMC are now legally responsible for remediating hazardous substances released into the environment on or from properties owned or operated by them as well as properties where they arranged for disposal of such substances, irrespective of when the release into the environment occurred or who caused it. That liability is often asserted on a joint and several basis with other prior and subsequent owners, operators and arrangers, meaning that each owner or operator of the property is, and each arranger may be, held fully responsible for the remediation, although in many cases some or all of the other responsible parties no longer exist, do not have the financial ability to respond or cannot be found. As a result, because of our acquisition of FMC, many of the subsidiary companies we now own are potentially responsible for a wide variety of environmental remediation projects throughout the U.S., and we expect to spend substantial sums annually for many years to address those remediation issues. We are also subject to claims where the release of hazardous substances is alleged to have damaged natural resources.

At December 31, 2022, we had more than 100 active remediation projects in 24 U.S. states. In addition, FMC and certain affiliates and predecessor companies were parties to agreements relating to the transfer of businesses or properties that contained indemnification provisions relating to environmental matters, and from time to time these provisions become the source of claims against us.

Our environmental obligation estimates are primarily based upon:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our knowledge and beliefs about complex scientific and historical facts and circumstances that in many cases occurred many decades ago;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our beliefs and assumptions regarding the nature, extent and duration of remediation activities that we will be required to undertake and the estimated costs of those remediation activities, which are subject to varying interpretations; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our beliefs regarding the requirements that are imposed on us by existing laws and regulations and, in some cases, the clarification of uncertain regulatory requirements that could materially affect our environmental obligation estimates.

Significant adjustments to these estimates are likely to occur in the future as additional information becomes available. The actual environmental costs may exceed our current and future accruals for these costs, and any such changes could be material.

In addition, remediation standards imposed by the U.S. Environmental Protection Agency and state environmental agencies have generally become more stringent over time and may become even more stringent in the future. Imposition of more stringent remediation standards, particularly for arsenic and lead in soils, poses a risk that additional remediation work could be required at our active remediation sites and at sites that we have already remediated to the satisfaction of the responsible governmental agencies, and may increase the risk of toxic tort litigation.

Refer to Items 1. and 2. "Business and Properties" and Note 12 for further discussion of our environmental obligations.

***We face increasing, complex and changing regulatory and stakeholder expectations relating to our climate and energy transition plans, which may adversely affect our business. Further, we may not be able to timely or successfully transition from fossil fuel sources for our significant energy needs, which may result in reputational damage.***

Our operations require significant energy, much of which is currently from fossil fuel sources and is obtained from third parties under long-term contracts. Energy represented approximately 21% of our copper mine site operating costs in 2022, and is expected to approximate 24% in 2023. The principal sources of energy consumption at our mining operations are: diesel fuel, which powers mine trucks and other transportation equipment; purchased electricity, which powers core facilities and certain on-site metal processing operations; and coal and natural gas, which provides electricity at certain operations.

Existing and proposed governmental conventions, laws, rules, regulations, policies and standards as well as existing and proposed voluntary disclosure standards and frameworks (both in the U.S. and internationally), including those related to climate and greenhouse gas (GHG) emissions, may in the future add significantly to our operating costs, limit or modify our operations, impact the competitiveness of the commodities we produce, and require more resources to comply and remediate in response. For additional information on climate change conventions, laws, regulations and standards applicable to FCX, refer to Items 1. and 2. "Business and Properties".

If we do not adapt to the expectations of stakeholders regarding a low-carbon future in a timely manner, it may result in reputational damage with key stakeholders, which can impact investor confidence, market value and access to, and cost of, capital. In response to climate change and societal and stakeholder demands for action, we have announced 2030 GHG emissions reduction targets and a 2050 net zero aspiration, which will result in additional costs to us, the totality of which we cannot currently estimate with accuracy, and we cannot guarantee that we will be able to achieve any current or future GHG emissions targets or aspirations.

While we strive to transition to more renewable power sources for our mining operations, as a commercial consumer of power, our ability to reduce our GHG emissions associated with our power consumption demand is dependent upon the mix of our suppliers and locally-available renewable energy resources at our various sites. The transition to renewable and other energy sources could, among other things, increase our capital expenditures, operating and energy costs, depending on the scope, magnitude and timing of increased regulation of fossil-fuel based energy production, including GHG emissions, as well as the availability of alternative energy sources.

In certain aspects of our operations, our ability to reduce our GHG emissions is directly dependent on the actions of third parties and technological solutions and innovation, and our ability to make significant, rapid changes in our GHG emissions in response to potential future regulations may be limited. For example, our diesel-fueled haul trucks are a significant contributor to GHG emissions at our North America and South America operations, but reduction of emissions from such haul trucks will depend upon the development and availability of commercially viable alternative-fueled mining equipment by our third-party suppliers. At our remote operations in Indonesia, we own and operate a coal-fired power plant, and our ability to transition to commercially viable alternative sources of energy will depend on, among other things, additional studies, technological considerations and permit approvals.

***The physical impacts of climate change may adversely affect our mining operations, workforce, communities, supply chains and customers, which may result in increased costs.***

We recognize that as the climate changes, our operations, workforce, communities, supply chains and customers may be exposed to changes in the frequency, intensity and/or duration of intense storms, drought, flooding (including from sea level rise at our coastal operations), wildfire, and other extreme weather events and patterns (such as extreme heat). Such potential physical impacts of climate change on our operations are highly uncertain, and would vary by operation based on particular geographic circumstances. At many of our mine sites, climate change is projected to impact local precipitation regimes, resulting in shorter-duration, higher-intensity storm events, and the potential for less precipitation overall. We could face increased operational costs associated with managing additional volumes of storm water during more intense future events, including supply disruption, delays, damage to or inaccessibility of our facilities and increased pricing of consumables and components we purchase. In addition, the potential for overall decreases in precipitation could affect the availability of water needed for our operations, leading to increased operating costs, or in extreme cases, disruptions to our mining operations. For additional information regarding risks relating to availability of water, see related risk factor above.

***Increasing scrutiny, action and evolving expectations from stakeholders with respect to our ESG practices, performance, commitments and disclosures may impact our reputation, increase our costs and impact our access to capital or business strategy.***

Stakeholder scrutiny related to our ESG practices, commitments, performance and disclosures continues to increase. We have adopted certain policies and programs, including with respect to responsible production frameworks, climate change, water stewardship, biodiversity and land management, tailings management and stewardship, waste management, safety and health, human capital management, human rights, social performance and community and Indigenous Peoples relations, political activity and spending practices, and supply chains/responsible sourcing. It is possible, however, that our stakeholders might not be satisfied with our ESG practices, goals, initiatives, commitments, performance and/or disclosures, or the speed of their adoption, implementation and measurable success. At the same time, certain stakeholders might not be satisfied that we have adopted ESG goals, initiatives and commitments at all. If we do not meet our stakeholders' evolving expectations, including any failure or perceived failure to achieve our stated goals and targets or industry standards or any allegations that our stated goals or targets should be altered, our reputation, access to and cost of capital, business strategy and stock price could be negatively impacted.

Investor advocacy groups, certain institutional investors, investment funds, creditors and other influential investors are increasingly focused on our ESG practices and in recent years have placed increasing importance on the ESG implications of their investments and lending decisions.

Organizations that provide information to investors and financial institutions on ESG performance and related matters have developed quantitative and qualitative data collection processes and ratings processes for evaluating companies on their approach to ESG matters. Such ratings are used by some investors to inform their investment and voting decisions. In addition, many investors have created their own proprietary ratings that inform their investment and voting decisions. Unfavorable ratings or assessment of our ESG practices, including our compliance with certain voluntary disclosure standards and frameworks, may lead to negative investor sentiment toward us, which could have a negative impact on our stock price and our access to and cost of capital.

Similarly, many financial institutions are increasingly incorporating ESG ratings or assessments into their credit risk assessments, and screen companies based on their ESG practices and performance when making lending decisions. If we are unable to meet the ESG lending criteria set by our creditors or are required to take certain remediation steps to satisfy such criteria, our access to capital on terms we find favorable may be limited and our costs may increase.

As we continue to focus on our ESG practices, goals, initiatives, commitments, performance and disclosures, and as ESG-related regulations and voluntary disclosure standards and frameworks continue to evolve, we have expanded our public disclosures in these areas. Such disclosures may reflect goals, aspirations, commitments, cost estimates and other expectations and assumptions, including over long timeframes, which are necessarily uncertain and may not be realized.

Further, the voluntary disclosure standards or frameworks we choose to align with are evolving and may change over time and our interpretation of such disclosure standards and frameworks may differ from those of others, either of which may result in a lack of consistent or meaningful comparative data from period to period and/or significant revisions to our goals and aspirations or reported progress in achieving such goals and aspirations.

Ensuring that there are adequate systems and processes in place to comply with the various ESG tracking and disclosure obligations will require management's time and expense. If we do not adapt to or comply with investor or stakeholder expectations, including with respect to evolving ESG disclosure standards and frameworks, or if we are perceived to have not responded appropriately, regardless of whether there is a legal requirement to do so, we may suffer from reputational damage and our business, financial condition, cost of capital and/or stock price could be materially and adversely affected.

In addition, our customers and end users may require that we implement certain additional ESG procedures or standards before they will start or continue to do business with us, which could lead to preferential buying based on our ESG practices compared to our competitors' ESG practices. Further, being associated with activities by suppliers, contractors or other affiliates that have or are perceived to have individual or cumulative adverse impacts on the environment, climate, biodiversity and land management, water access and management, human rights or cultural heritage could negatively affect our reputation and impose additional costs.

------

***Failure or the perceived failure to manage our relationships with the communities and/or Indigenous Peoples where we operate or that are near our operations could harm our reputation and social license to operate.***

Our relationships with the communities and/or Indigenous Peoples where we operate or that are adjacent to or near our operations are critical to the long-term success of our existing operations and the development of any future projects. There is ongoing and increasing stakeholder concern relating to a company's social license to operate and the perceived effects of mining activities on the environment and on communities impacted by such activities. We may engage in activities, such as exploration, production, construction or expansion of our operations that have or are perceived to have adverse impacts on the local communities and their relevant stakeholders, society as a whole, Indigenous Peoples, cultural heritage, human rights and the environment, among other things. For example, our operations may take place on or adjacent to Indigenous Peoples' ancestral lands, and such Indigenous Peoples may assert rights to the lands where we operate. Further, we may be required or expected by our stakeholders to consult with and/or obtain consent from Indigenous Peoples with respect to these operations.

In addition, our assets are generally long-lived and stakeholders' perceptions and expectations can change over the life of the mine. Changes in the aspirations and expectations of local communities and/or Indigenous Peoples where we operate, with respect to our employee health and safety performance and our contributions to infrastructure, community development, environmental management and other factors could affect our social license to operate and reputation, and could lead to delays and/or increased costs if expansions or new projects are blocked either temporarily or for extended periods. Failure to effectively engage with communities on an ongoing basis, including the withdrawal of consent or support of Indigenous Peoples, or other stakeholders, could adversely impact our business, damage our reputation and/or result in loss of rights to explore, operate or develop our projects.

**<u>Risks related to our common stock</u>**

***Our holding company structure may impact our ability to service our debt, declare dividends, and repurchase shares and debt.***

We are a holding company with no material assets other than the capital stock and intercompany receivables of our subsidiaries. As a result, our ability to service our indebtedness, pay dividends, and repurchase shares and debt is dependent on the generation of cash flows by our subsidiaries and their ability to make such cash available to us, by dividend, loan, debt repayment or otherwise. Our subsidiaries do not have any obligation to make funds available to us to service our indebtedness, pay dividends, or repurchase shares and debt. Dividends from subsidiaries that are not wholly owned are shared with other equity owners. Cash at our international operations is also typically subject to foreign withholding taxes upon repatriation into the U.S.

In addition, our subsidiaries may not be able to, or be permitted to, make distributions to us or repay loans to us, to enable us to service our indebtedness, pay dividends, or repurchase shares and debt. Each of our subsidiaries is a distinct legal entity and, under certain circumstances, legal restrictions, as well as the financial condition and operating requirements of our subsidiaries, may limit our ability to obtain cash from our subsidiaries. Certain of our subsidiaries are parties to credit agreements that restrict their ability to make distributions or loan repayments to us if such subsidiary is in default under such agreements, or to transfer substantially all of the assets of such subsidiary without the consent of the lenders. Our rights to participate in any distribution of our subsidiaries' assets upon their liquidation, reorganization or insolvency would generally be subject to the prior claims of the subsidiaries' creditors, including any trade creditors.

As more fully described in Note 10, during 2021, our Board of Directors (Board) adopted a performance-based payout framework, which currently includes base and variable dividends and a share repurchase program. Our ability to continue to pay dividends (base or variable) and the timing and amount of any share repurchases is at the discretion of our Board and management, respectively, and is subject to a number of factors, including maintaining our net debt target, capital availability, our financial results, cash requirements, global economic conditions, changes in laws, contractual restrictions and other factors deemed relevant by our Board or management, as applicable. Repurchases of our common stock under our repurchase program are discretionary up to the Board-approved limit, and our share repurchase program may be modified, increased, suspended or terminated at any time at the Board's discretion. Our dividend payments and share repurchases may change, and there can be no assurance that we will continue to declare dividends or repurchase shares at all or in any particular amounts. A reduction or suspension in our dividend payments or share repurchases could have a negative effect on the price of our common stock.

------

***Anti-takeover provisions in our charter documents and Delaware law may make an acquisition of us more difficult.***

Anti-takeover provisions in our charter documents and Delaware law may make an acquisition of us more difficult. These provisions may discourage potential takeover attempts, discourage bids for our common stock at a premium over market price or adversely affect the market price of, and the voting and other rights of the holders of, our common stock. These provisions could also discourage proxy contests and make it more difficult for stockholders to elect directors other than the candidates nominated by the Board. Refer to Exhibit 4.1 for further discussion of our anti-takeover provisions.

Further, our By-Laws provide to the fullest extent permitted by law that unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have, or declines to accept, jurisdiction, the U.S. District Court for the District of Delaware) will be the sole and exclusive forum for any (i) derivative action or proceeding brought on our behalf, (ii) action asserting a claim that is based upon a violation of a duty by any of our current or former directors, officers, employees or stockholders in such capacity, (iii) action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law or to which the Delaware General Corporation Law confers jurisdiction upon the Court of Chancery of the State of Delaware, (iv) action asserting a claim governed by the internal affairs doctrine, or (v) action asserting an "internal corporate claim" as that term is defined in Section 115 of the Delaware General Corporation Law. The exclusive forum provision may increase costs to bring a claim, discourage claims or limit a stockholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us or our directors, officers and other employees. Alternatively, if a court were to find the exclusive forum provision contained in our By-Laws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions. The exclusive forum provision in our By-laws will not preclude or contract the scope of exclusive federal or concurrent jurisdiction for actions brought under the federal securities laws including the Securities Exchange Act of 1934, as amended, or the Securities Act of 1933, as amended, or the respective rules and regulations promulgated thereunder.

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which may prohibit large stockholders from consummating a merger with, or acquisition of, us.

These provisions may deter an acquisition of us that might otherwise be attractive to our stockholders.

**Item 1B. Unresolved Staff Comments.**

Not applicable.

**Item 3. Legal Proceedings.**

Below is a discussion of our material pending legal proceedings not otherwise required to be disclosed in our Notes to Consolidated Financial Statements. Refer to Note 12 for a discussion of other material pending legal proceedings.

In addition to the material pending legal proceedings discussed below and in Note 12, we are involved periodically in ordinary routine litigation incidental to our business and not required to be disclosed, some of which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief.

United States (U.S.) Securities and Exchange Commission (SEC) regulations require us to disclose environmental proceedings involving a governmental authority if we reasonably believe that such proceedings may result in monetary sanctions above a stated threshold. Pursuant to the SEC regulations, we use a threshold of $1 million for purposes of determining whether disclosure of any such environmental proceedings is required.

Management does not believe, based on currently available information, that the outcome of any currently pending legal proceeding will have a material adverse effect on our financial condition; although individual or cumulative outcomes could be material to our operating results for a particular period, depending on the nature and magnitude of the outcome and the operating results for the period.

**Water Rights Adjudications**

Our operations in the western U.S. require significant secure quantities of water for mining and ore processing activities, and related support facilities. Continuous operation of our mines is dependent on, among other things, our ability to maintain our water rights and claims and the continuing physical availability of the water supplies. In the arid western U.S., where certain of our mines are located, water rights are often contested, and disputes over water rights are generally time-consuming, expensive and not necessarily dispositive unless they resolve both actual and potential claims. The loss of a water right or a currently available water supply could force us to curtail operations, or force premature closures, thereby increasing and/or accelerating costs or foregoing profitable operations.

At our North America operations, certain of our water supplies are supported by surface water rights, which give us the right to use public waters for a statutorily defined beneficial use at a designated location. In Arizona, where our operations use both surface and groundwater, we are a participant in an active adjudication in which Arizona courts have been attempting, for over 45 years, to quantify and prioritize surface water claims for the Gila River system, one of the state's largest river systems. This Gila River adjudication primarily affects our Morenci, Safford (including Lone Star) and Sierrita mines. The Gila River adjudication is addressing the state law claims of thousands of competing users, including us, as well as significant federal water claims that are potentially adverse to the state law claims of both surface water and groundwater users. Groundwater is treated differently from surface water under Arizona law, which historically allowed land owners to pump unlimited quantities of subsurface water, subject only to the requirement of putting it to "reasonable use." However, court decisions in the adjudication have concluded that some subsurface water constitutes "subflow" that is to be treated legally as surface water and is therefore subject to the Arizona doctrine of prior appropriation and to the adjudication, and potentially unavailable to groundwater pumpers, including us, in the absence of valid surface water claims. Any re-characterization of groundwater as surface water could affect the ability of consumers, farmers, ranchers, municipalities, and industrial users like us to continue to access water supplies that have been relied on for decades. Because we are a user of both groundwater and surface water in Arizona, we are an active participant in the Gila River adjudication.

<u>In Re The General Adjudication of All Rights to Use Water in the Gila River System and Sources</u>, Maricopa County, Superior Court, Cause Nos. W-1 (Salt), W-2 (Verde), W-3 (Upper Gila), and W-4 (San Pedro). This case was originally initiated in 1974 with the filing of a petition with the Arizona State Land Department and was consolidated and transferred to the Maricopa County Superior Court in 1981. The principal parties, in addition to us, include: Arizona Public Service Company, ASARCO, LLC; BHP Copper, Inc; the state of Arizona; various cities and towns and water companies; the Gila Valley Irrigation District; the Franklin Irrigation District; the San Carlos Irrigation and Drainage District; the Salt River Project; the San Carlos Apache Tribe; the Gila River Indian Community; and the U.S. on behalf of those tribes, on its own behalf, and on behalf of the White Mountain Apache Tribe, the Fort McDowell Mohave-Apache Indian Community, the Salt River Pima-Maricopa Indian Community, and the Payson Community of Yavapai Apache Indians. Prior to January 1, 1983, various Indian tribes filed separate suits in the U.S. District Court in Arizona claiming superior rights to water being used by many other parties, including us, and claiming damages for prior use in derogation of their allegedly superior rights. These federal proceedings have been stayed in favor of the adjudications pending in Arizona state courts, and some of the federal suits have since been settled.

In 2005, the Maricopa County Superior Court directed the Arizona Department of Water Resources (ADWR) to prepare detailed recommendations regarding the delineation of the "subflow" zone of the San Pedro River, a tributary of the Gila River. Subsurface water within the subflow zone is presumed to constitute appropriable subflow rather than groundwater. Although we have minimal interests in the San Pedro River Basin, a decision that re-characterizes groundwater in that basin as appropriable subflow may set a precedent for other river systems in Arizona that could have material implications for many commercial, industrial, municipal and agricultural users of groundwater, including our Arizona operations. In 2017, the court approved ADWR's proposed subflow zone maps; water pumped from wells located inside the mapped subflow zone is now presumed to be appropriable subflow. No party has appealed that decision.

ADWR is now in the process of preparing subflow delineations for the applicable watercourses in the Verde River watershed. In December 2021, ADWR issued a report proposing a subflow delineation for the Verde River mainstem and Sycamore Creek and objections to that report were submitted in May 2022. While we do not have any active mining operations in the Verde River watershed that would be impacted by this phase of the adjudication, we filed a set of limited objections on issues that could set a precedent for other watersheds in Arizona that could have material implications for many users of groundwater, including our Arizona operations, and our objections have not been resolved.

------

In 2014, ADWR submitted a proposal for the development of procedures for "cone of depression" analyses to determine whether a well located outside of the subflow zone creates a cone of depression that intersects the subflow zone. Based on these cone of depression analyses, wells outside of the subflow zone could be subject to the adjudications pending in Arizona state courts. In the absence of a valid surface water claim to support the pumping, owners of wells deemed to be depleting the subflow zone through their cones of depression may be subject to claims that they must refrain from pumping subflow or must pay damages. In January 2017, ADWR issued a report containing its recommended cone of depression test.

On November 14, 2018, the Special Master for the Gila River adjudication issued a final decision rejecting ADWR's recommended cone of depression test, adopting our position that a numeric model capable of accounting for complexities of the aquifer system should be used. However, the Special Master confirmed that the cone of depression test would be the initial test for determining which wells are subject to the adjudications, rather than proving that a well is pumping subflow or establishing how much of a well's water production is subflow. Such matters will be determined by a subsequent "subflow depletion test," which is expected to be proposed by ADWR in 2023. While some of our adversaries objected to the Special Master's final decision, in July 2022, the Arizona Superior Court issued a decision affirming the Special Master's decision in all respects. No party has appealed that decision.

In December 2018, ADWR submitted its initial report on the "subflow depletion test," noting that the test will specify the methodology a well owner must use to quantify the portion of the water drawn from a well that is subflow as opposed to groundwater. The Special Master has ordered ADWR to schedule meetings in 2023 to discuss progress on developments of the test, with a deadline of December 2023 for ADWR's report setting forth its proposed depletion test. Objections to such report are expected to be due in February 2024. We, along with the other parties, will have the opportunity to provide inputs throughout the process.

An issue litigated in the 2018 proceeding concerned whether for the subflow depletion test the subflow zone should be represented in the numeric model as extending only as deep as the bottom of the floodplain alluvium or extend all the way down to bedrock. In August 2021, the Special Master issued an order recognizing our position that if the vertical extent of the subflow zone is extended below the floodplain alluvium, it would result in overstated depletion calculations. Accordingly, the Special Master ordered that the vertical boundary of the subflow zone be restricted to the floodplain alluvium. No party has appealed that decision, and we expect the guidance from the Special Master's order to be reflected in ADWR's subflow depletion test report (due December 2023).

In proceedings separate from the development of the subflow depletion test, in June 2020, the Special Master designated legal questions to be resolved concerning a well owner's ability to obtain a surface water right for subsurface water that, while initially believed to be non-appropriable groundwater, is ultimately determined to be appropriable subflow. In April 2021, the Special Master ruled that, for uses initiated after enactment of the 1919 permitting statute, a well owner may not pursue a surface water right for subsurface water now unless the well owner filed an application for a permit to appropriate prior to initiating the water use. We, along with allied parties, have objected to the Special Master's ruling and are awaiting further proceedings before the Arizona Superior Court. Regardless of the outcome in the Arizona Superior Court, we anticipate this issue will be appealed to the Arizona Supreme Court.

As part of the adjudications, the U.S. has asserted numerous claims for express and implied "reserved" surface water and groundwater rights on Indian and non-Indian federal lands throughout Arizona. These claims are related to reservations of federal land for specific purposes (*e.g.,* Indian reservations, national parks, military bases and wilderness areas). Unlike state law-based water rights, federal reserved water rights are given priority in the "prior appropriation" system based on the date the land was reserved, not the date that water was first used on the land. In addition, federal reserved water rights may enjoy greater protection from groundwater pumping than is accorded to state law-based water rights.

In multiple instances, the U.S. asserts a right to all water in a particular watershed that was not effectively appropriated under state law prior to the establishment of the federal reservation. This creates risks for both surface water users and groundwater users because such expansive claims may severely impede competing uses of water within the same watershed. Because there are numerous federal reservations in watersheds across Arizona, the reserved water right claims of the U.S. pose a significant risk to multiple operations, including Morenci and Safford (including Lone Star) in the Upper Gila River watershed, and Sierrita in the Santa Cruz watershed. Because federal reserved water rights may adversely affect water uses at each of these operations, we have been actively involved in litigation over these claims. Because federal reserved water rights have not yet been quantified, the task of

------

determining how much water each federal reservation may use has been left to the Arizona Superior Court handling the Gila River adjudication. Several "contested cases" to quantify reserved water rights for particular federal reservations in Arizona are currently pending with only two resolved at this time. The first resolved decision was issued in <u>In re Aravaipa Canyon Wilderness Area,</u> which was to resolve the U.S.'s claims to water for the Aravaipa Canyon Wilderness Area. The court issued a decision in December 2018 supportive of our position on almost all issues, rejecting the U.S.'s argument that wilderness areas are entitled to all water that was not appropriated at the time the reservation was created. The second resolved decision was issued in <u>In re</u> <u>Redfield Canyon Wilderness Area</u>, which was another case to resolve claims for a wilderness area. The court issued its decision in August 2022 supportive of our position on almost all issues, denying the U.S.'s federal reserved water rights claims for the wilderness area. The U.S. declined to pursue an interlocutory appeal in either of the <u>In re Aravaipa Canyon Wilderness Area</u> or <u>In re Redfield Canyon Wilderness Area</u> cases, and we believe the rulings in those cases will support our positions in other pending federal reserved water right cases, including: <u>In re Fort Huachuca</u>, which involves the U.S.'s claims to water for an Arizona army base and is awaiting a decision following a trial which concluded in February 2017; and <u>In re San Pedro Riparian National Conservation Area</u>, which involves the U.S.'s claims to water for a national conservation area and is awaiting a decision following a trial which concluded in May 2018. In January 2023, the U.S. filed several federal reserved water rights claims for federal reservations in portions of the Verde River watershed, and we anticipate that the Special Master will establish litigation schedules to resolve the claims for those reservations.

Given the legal and technical complexity of these adjudications, their long history, and their long-term legal, economic and political implications, it is difficult to predict the timing or the outcome of these proceedings. If we are not able to satisfactorily resolve the issues being addressed in the adjudications, our ability to pump groundwater could be diminished or curtailed, and our operations and any future expansions at Morenci, Safford (including Lone Star) and Sierrita could be adversely affected unless we are able to acquire alternative water resources.

**Item 4. Mine Safety Disclosures.**

Our highest priority is the health, safety and well-being of our workforce. We believe that health and safety considerations are integral to, and fundamental for, all other functions in our organization, and we understand that the health and safety of our workforce is critical to our operational efficiency and long-term success. Our global health and safety approach, "Safe Production Matters," is focused on fatality prevention and continuous improvement through the use of robust management systems, empowering safe work behaviors and strengthening our safety culture.

Our objective is to achieve zero workplace fatalities and to decrease injuries and occupational illnesses. We measure progress toward achieving our objective against regularly established benchmarks, including measuring company-wide Total Recordable Incident Rates (TRIR). Our TRIR (including contractors) per 200,000 man-hours worked was 0.77 in 2022 and 0.70 in 2021. The metal mining sector industry average per 200,000 man-hours worked reported by the U.S. Mine Safety and Health Administration was 1.83 for 2022 (preliminary for the period of January 1, 2022, through September 30, 2022) and 1.71 in 2021. Refer to Exhibit 95.1 for mine safety disclosures required in accordance with Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of SEC Regulation S-K.

In December 2022, our Board declared cash dividends totaling $0.15 per share on our common stock (including a $0.075 per share quarterly base cash dividend and a $0.075 per share variable, performance-based cash dividend), which was paid on February 1, 2023, to shareholders of record as of January 13, 2023. Based on current market conditions, the base and variable dividends on our common stock are anticipated to total $0.60 per share for 2023 (including the dividends paid on February 1, 2023), comprised of a $0.30 per share base dividend and $0.30 per share variable dividend. The declaration and payment of dividends (base or variable) is at the discretion of our Board and will depend upon our financial results, cash requirements, global economic conditions and other factors deemed relevant by our Board. See "Cautionary Statement" in Items 7. and 7A. "Management's Discussion and Analysis of Financial Condition and Results of Operations and Quantitative and Qualitative Disclosures About Market Risk" and Note 10 for further discussion.

**OVERVIEW**

We are a leading international mining company with headquarters in Phoenix, Arizona. We operate large, long-lived, geographically diverse assets with significant proven and probable mineral reserves of copper, gold and molybdenum. We are one of the world's largest publicly traded copper producers. Our portfolio of assets includes the Grasberg minerals district in Indonesia, one of the world's largest copper and gold deposits; and significant mining operations in North America and South America, including the large-scale Morenci minerals district in Arizona and the Cerro Verde operation in Peru.

Our results for 2022 reflect solid execution of our operating plan, which resulted in strong operating performance and cash flow generation allowing for increased cash returns to shareholders. Our execution led to growth in consolidated copper and gold production and sales volumes when compared to the prior year. Despite lower average realized copper prices, increased production and delivery costs, and economic uncertainty, we continued to generate positive operating income and operating cash flows. We believe the actions we have taken in recent years to build a solid balance sheet, successfully expand low-cost operations, and maintain flexible organic growth options while maintaining liquidity allow us to continue to execute our business plans in a prudent manner and preserve substantial future asset values.

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

Net income attributable to common stock totaled $3.5 billion in 2022 and $4.3 billion in 2021. Our results in 2022, compared to 2021, primarily reflect lower average realized copper prices and increased costs for energy, sulfuric acid, and maintenance and supplies, partly offset by higher copper and gold sales volumes. Refer to "Consolidated Results" for discussion of items impacting our consolidated results for the two years ended December 31, 2022.

At December 31, 2022, we had consolidated debt of $10.6 billion and consolidated cash and cash equivalents of $8.1 billion, resulting in net debt of $2.5 billion ($1.3 billion excluding net debt for the greenfield smelter and precious metals refinery (PMR) in Indonesia - collectively, the Indonesia smelter projects). Refer to "Net Debt" for reconciliations of consolidated debt and consolidated cash and cash equivalents to net debt.

During 2022, we purchased approximately $1.1 billion aggregate principal amount of our senior notes in open-market transactions for a total cost of $1.0 billion, resulting in annual cash interest savings of approximately $50 million. In October 2022, we entered into a $3.0 billion revolving credit facility that matures in October 2027 and replaced our prior revolving credit facility. At December 31, 2022, we had no borrowings and $3.0 billion available under our revolving credit facility, and PT Freeport Indonesia (PT-FI) and Cerro Verde had $1.3 billion and $350 million, respectively, of availability under their revolving credit facilities. Refer to Note 8 and "Capital Resources and Liquidity" for further discussion.

During 2022, we acquired 35.1 million shares of our common stock under our share repurchase program for a total cost of $1.3 billion ($38.36 average cost per share) and declared cash dividends totaling $0.60 per share on our common stock (which included both base and variable, performance-based cash dividends). Approximately $3.2 billion remains available under our $5.0 billion share repurchase program. Refer to Note 10 and "Capital Resources and Liquidity" for further discussion.

We have significant mineral reserves, mineral resources and future development opportunities within our portfolio of mining assets. At December 31, 2022, our estimated consolidated recoverable proven and probable mineral reserves totaled 111.0 billion pounds of copper, 26.9 million ounces of gold and 3.53 billion pounds of molybdenum. Refer to Note 17 and "Critical Accounting Estimates - Mineral Reserves" for further discussion.

During 2022, production from our mines totaled 4.2 billion pounds of copper, 1.8 million ounces of gold and 85 million pounds of molybdenum. Following is the allocation of our consolidated copper, gold and molybdenum production in 2022 by geographic location:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | Copper | Gold | Molybdenum | |
| North America | 35% | 1% | 73% | <sup>a</sup> |
| South America | 28 |  | 27 |  |
| Indonesia | 37 | 99 |  |  |
|  | 100% | 100% | 100% |  |

---

a.Our North America copper mines produced 34% of consolidated molybdenum production, and our Henderson and Climax molybdenum mines produced 39%.

Copper production from the Morenci mine in North America, Cerro Verde mine in Peru and the Grasberg minerals district in Indonesia together totaled 75% of our consolidated copper production in 2022.

**OUTLOOK**

Our financial results vary as a result of fluctuations in market prices primarily for copper, gold and, to a lesser extent, molybdenum, as well as other factors. World market prices for these commodities have fluctuated historically and are affected by numerous factors beyond our control. Beginning in 2020, with the onset of the COVID-19 pandemic, and continuing in 2022 because of a series of macro-economic factors, there has been significant volatility in the financial and commodities markets, including the copper market. Market sentiment improved beginning in late 2022 and we believe the outlook for copper fundamentals in the medium- and long-term are favorable. Refer to "Markets" and Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, for further discussion. Because we cannot control the price of our products, the key measures that management focuses on in operating our business are sales volumes, unit net cash costs, operating cash flows and capital expenditures. In addition, to the measures noted below and as further discussed in Note 3, beginning January 1, 2023, our economic interest in PT-FI changes from approximately 81% to 48.76%, and accordingly, net income attributable to noncontrolling interests is expected to increase in 2023.

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

**Sales Volumes** 

Following are our projected consolidated sales volumes for 2023 and actual consolidated sales volumes for 2022:

---

| | | | |
|:---|:---|:---|:---|
| | 2023<br>(Projected) | | 2022<br>(Actual) |
| **Copper** (millions of recoverable pounds): |  |  |  |
| &nbsp;&nbsp;&nbsp;North America copper mines | 1460 |  | 1469 |
| &nbsp;&nbsp;&nbsp;South America mining | 1200 |  | 1162 |
| &nbsp;&nbsp;&nbsp;Indonesia mining | 1500 |  | 1582 |
| &nbsp;&nbsp;&nbsp;**Total** | 4160 |  | 4213 |
| **Gold** (thousands of recoverable ounces) | 1700 |  | 1823 |
| **Molybdenum** (millions of recoverable pounds) | 80 | <sup>a</sup> | 75 |

---

a.Includes 50 million pounds from our North America and South America copper mines and 30 million pounds from our Molybdenum mines.

Projected sales volumes are dependent on operational performance, weather-related conditions, timing of shipments, PT-FI's continued ability to export copper concentrate, including the extension of PT-FI's export license after March 19, 2023, PT Smelting and PT-FI's continued ability to export anode slimes and other factors.

Since February 11, 2023, PT-FI's operations have been temporarily disrupted because of significant rainfall and landslides, which restricted access to infrastructure near its milling operations. Recovery activities are in progress to clear debris from the affected areas and PT-FI is in the process of gradually resuming operations. Operations are expected to be fully restored by the end of February 2023.

As a result of this disruption, we expect our first-quarter 2023 sales volumes to be lower than previously expected. If PT-FI is not able to resume operations as currently expected or on our anticipated timeline, our results of operations may be further impacted.

For further discussion of the February 2023 weather event at PT-FI's operations and other important factors that could cause results to differ materially from projections, refer to "Cautionary Statement" below and Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022.

**Consolidated Unit Net Cash Costs**

Our operations have been impacted by inflationary cost pressures, including increased costs for energy, sulfuric acid, and maintenance and supplies. Historically, copper prices have been correlated to various input costs, including energy and other commodity-related consumables. During 2022, prices for a number of commodity-related consumables increased at a time when copper prices declined. While prices for a number of commodity-related consumables have retreated from the highs of 2022, most cost elements remain high relative to long-term correlations. In addition, labor constraints, particularly in the U.S., continue to limit production levels. We plan to continue to carefully manage costs and drive efficiencies to mitigate cost increases.

Assuming average prices of $1,900 per ounce of gold and $20.00 per pound of molybdenum and achievement of current sales volume and cost estimates, consolidated unit net cash costs (net of by-product credits) for our copper mines are expected to average $1.60 per pound of copper in 2023. The impact of price changes on 2023 consolidated unit net cash costs would approximate $0.04 per pound of copper for each $100 per ounce change in the average price of gold and $0.02 per pound of copper for each $2 per pound change in the average price of molybdenum. Quarterly unit net cash costs vary with fluctuations in sales volumes and realized prices, primarily for gold and molybdenum.

**Consolidated Operating Cash Flows** 

Our consolidated operating cash flows vary with sales volumes; prices realized from copper, gold and molybdenum sales; production costs; income taxes; other working capital changes; and other factors. Based on current sales volume and cost estimates, and assuming average prices of $4.00 per pound of copper, $1,900 per ounce of gold and $20.00 per pound of molybdenum, our consolidated operating cash flows are estimated to approximate $7.2 billion (including $0.1 billion of working capital and other sources) for the year 2023. Estimated consolidated operating cash flows in 2023 also reflect a projected income tax provision of $2.5 billion (refer to "Consolidated Results - Income Taxes" for further discussion of our projected income tax rate, including potential impacts of the provisions of the U.S. Inflation Reduction Act of 2022 (the Act), for the year 2023). The impact of price changes

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

during 2023 on operating cash flows would approximate $440 million for each $0.10 per pound change in the average price of copper, $170 million for each $100 per ounce change in the average price of gold and $120 million for each $2 per pound change in the average price of molybdenum.

**Consolidated Capital Expenditures**

Capital expenditures for the year 2023 are expected to approximate $5.2 billion (including $2.3 billion for major mining projects and $1.8 billion for the Indonesia smelter projects). Projected capital expenditures for major mining projects include $1.3 billion for planned projects primarily associated with underground mine development in the Grasberg minerals district and supporting mill and power capital costs and $1.0 billion for discretionary growth projects (primarily for development of Kucing Liar, a mill recovery project with the installation of a new copper cleaner circuit at PT-FI, an electronic material recycle project at Atlantic Copper and an expansion project at Lone Star). We closely monitor market conditions and will continue to adjust our operating plans, including capital expenditures, to protect our liquidity and preserve our asset values, as necessary.

Capital expenditures for the Indonesia smelter projects are being funded with proceeds from PT-FI's senior notes and its available revolving credit facility. Construction of the additional domestic smelter capacity will result in the elimination of export duties, providing an offset to the economic cost associated with the Indonesia smelter projects.

**Noncontrolling Interests** 

Net income attributable to noncontrolling interests is primarily associated with PT-FI, Cerro Verde and El Abra and totaled $1.0 billion for the year 2022 (which represented 15% of our consolidated income before income taxes). As further described in Note 3, in December 2018, we completed the transaction with the Indonesia government regarding PT-FI's long-term mining rights and share ownership (the 2018 Transaction). The arrangements related to the 2018 Transaction provided for us and the other pre-transaction PT-FI shareholders to initially retain the economics of the revenue and cost sharing arrangements under the former unincorporated joint venture with Rio Tinto plc (Rio Tinto). As a result, our economic interest in PT-FI approximated 81% through 2022, and beginning January 1, 2023, is 48.76% (refer to Note 3 for further discussion of attribution of PT-FI net income). Therefore, beginning in 2023, net income attributable to noncontrolling interests will reflect the noncontrolling parties' 51.24% share of PT-FI net income. Based on current sales volume and cost estimates and assuming average prices of $4.00 per pound of copper, $1,900 per ounce of gold and $20.00 per pound of molybdenum and taking into account the change in our economic interest in PT-FI, net income attributable to noncontrolling interests is estimated to approximate $2.3 billion for the year 2023 (which would represent 29% of our consolidated income before income taxes). The actual amount will depend on many factors, including relative performance of each business segment, commodity prices, costs and other factors.

**MARKETS**

World prices for copper, gold and molybdenum can fluctuate significantly. During the period from January 2013 through December 2022, the London Metal Exchange (LME) copper settlement price varied from a low of $1.96 per pound in 2016 to a record high of $4.87 per pound in 2022; the London Bullion Market Association (London) PM gold price fluctuated from a low of $1,049 per ounce in 2015 to a record high of $2,067 per ounce in 2020, and the *Platts Metals Daily* Molybdenum Dealer Oxide weekly average price ranged from a low of $4.46 per pound in 2015 to a high of $31.37 per pound in 2022. Copper, gold and molybdenum prices are affected by numerous factors beyond our control as described further in Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022.

![fcx-20221231_g16.jpg](fcx-20221231_g16.jpg)

This graph presents LME copper settlement prices and the combined reported stocks of copper at the LME, Commodity Exchange Inc., and the Shanghai Futures Exchange from January 2013 through December 2022. For the year 2022, the LME copper settlement prices ranged from a high of $4.87 per pound in March (record high) to a low for the year of $3.18 per pound in July, closed at $3.80 per pound on December 30, 2022, and averaged $3.99 per pound for the year. Current physical market conditions are strong as evidenced by low levels of global exchange stocks, and our global customer base reports continued healthy demand for copper. Improved market sentiment beginning in late 2022 was associated with prospects for improved demand from China, rising demand from global decarbonization initiatives, supply constraints, United States (U.S.) dollar exchange rates and low inventories. Despite near-term uncertainties in the global economy and potential volatility in the copper market, we believe the outlook for copper fundamentals in the medium- and long-term are favorable, with third-party studies indicating that demand for copper may double in 15 years as a result of global decarbonization trends. We believe substantial new mine supply development will be required to meet the goals of the global energy transition, and higher copper prices will be required to support new mine supply development. The LME copper settlement price was $4.12 per pound on January 31, 2023.

We believe long-term fundamentals for copper are favorable and that future demand will be supported by copper's role in the global transition to renewable power, electric vehicles and other carbon-reduction initiatives, and continued urbanization in developing countries. The small number of approved, large-scale projects beyond those that have been announced, the long lead times required to permit and build new mines and declining ore grades at existing operations continue to highlight the fundamental supply challenges for copper.

Gold prices were positively impacted at the end of 2022, by market views that the strength of the U.S. dollar will not be sustained. The London PM gold price was $1,924 per ounce on January 31, 2023.

This graph presents the *Platts Metals Daily* Molybdenum Dealer Oxide weekly average price from January 2013 through December 2022. For the year 2022, the weekly average price for molybdenum ranged from a low of $14.10 per pound in August to a high of $31.37 per pound in December, averaged $18.82 per pound and was $31.37 per pound on December 30, 2022. Higher molybdenum prices at the end of 2022 reflect tight supply and steady demand. The *Platts Metals Daily* Molybdenum Dealer Oxide weekly average price was $36.75 per pound on January 31, 2023.

**CRITICAL ACCOUNTING ESTIMATES**

MD&A is based on our consolidated financial statements, which have been prepared in conformity with generally accepted accounting principles (GAAP) in the U.S. The preparation of these statements requires that we make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. We base these estimates on historical experience and on assumptions that we consider reasonable under the circumstances; however, reported results could differ from those based on the current estimates under different assumptions or conditions. The areas requiring the use of management's estimates are also discussed in Note 1 under the subheading "Use of Estimates." Management has reviewed the following discussion of its development and selection of critical accounting estimates with the Audit Committee of our Board of Directors (the Board).

**Taxes**

Refer to Note 11 and Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, for further discussion of our consolidated income taxes.

In preparing our consolidated financial statements, we estimate the actual amount of income taxes currently payable or receivable as well as deferred income tax assets and liabilities attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities of a change in tax rates or laws is recognized in income in the period in which such changes are enacted.

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

Our operations are in multiple jurisdictions where uncertainties arise in the application of complex tax regulations. Some of these tax regimes are defined by contractual agreements with the local government, while others are defined by general tax laws and regulations. We and our subsidiaries are subject to reviews of our income tax filings and other tax payments, and disputes can arise with the taxing authorities over the interpretation of our contracts or laws. Refer to Note 11 for net charges recorded for historical contested tax matters in Indonesia.

In August 2022, the Act was signed into law, which had no impact on our 2022 financial results. The provisions of the Act are applicable to us beginning January 1, 2023. Additional guidance related to how the Corporate Alternative Minimum Tax (CAMT) provisions of the Act will be applied or otherwise administered is yet to be released by the U.S. Department of the Treasury, and may differ from our interpretations. We will continue to analyze the impacts as additional guidance is available. We expect the CAMT provisions will impact our U.S. tax position, and may further limit our ability to benefit from our U.S. net operating losses (NOLs). Refer to "Consolidated Results" for further discussion of the Act.

We operate in the U.S. and multiple international tax jurisdictions, and our income tax returns are subject to examination by tax authorities in those jurisdictions who may challenge any tax position on these returns. Uncertainty in a tax position may arise because tax laws are subject to interpretation. We use significant judgment to (1) determine whether, based on the technical merits, a tax position is more likely than not to be sustained and (2) measure the amount of tax benefit that qualifies for recognition.

We have uncertain tax positions related to income tax assessments in Indonesia and Peru, including penalties and interest, which have not been recorded at December 31, 2022. Final taxes paid may be dependent upon many factors, including negotiations with taxing authorities. In certain jurisdictions, we pay a portion of the disputed amount before formally appealing an assessment. Such payment is recorded as a receivable if we believe the amount is collectible. Refer to Note 12 for further discussion.

A valuation allowance is provided for those deferred income tax assets for which the weight of available evidence suggests that the related benefits will not be realized. In determining the amount of the valuation allowance, we consider estimated future taxable income or loss as well as feasible tax planning strategies in each jurisdiction. If we determine that we will not realize all or a portion of our deferred income tax assets, we will increase our valuation allowance. Conversely, if we determine that we will ultimately be able to realize all or a portion of the related benefits for which a valuation allowance has been provided, all or a portion of the related valuation allowance will be reduced. Our valuation allowances totaled $4.0 billion at December 31, 2022, which covered all of our U.S. foreign tax credits and U.S. federal NOLs, substantially all of our U.S. state NOLs, as well as a portion of our U.S. federal, state and foreign deferred tax assets and foreign NOLs. During 2022, valuation allowances decreased by $102 million.

**Environmental Obligations**

Refer to Notes 1 and 12, and Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, for further discussion of environmental obligations, including a summary of changes in our estimated environmental obligations for the three years ended December 31, 2022.

Our current and historical operating activities are subject to various national, state and local environmental laws and regulations that govern the protection of the environment, and compliance with those laws requires significant expenditures. Environmental expenditures are charged to expense or capitalized, depending upon their future economic benefits. The guidance provided by U.S. GAAP requires that liabilities for contingencies be recorded when it is probable that obligations have been incurred, and the cost can be reasonably estimated. At December 31, 2022, environmental obligations recorded in our consolidated balance sheet totaled $1.7 billion, which reflect obligations for environmental liabilities attributed to the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) or analogous state programs and for estimated future costs associated with environmental matters.

Accounting for environmental obligations represents a critical accounting estimate because (i) changes to environmental laws and regulations and/or circumstances affecting our operations could result in significant changes to our estimates, which could have a significant impact on our results of operations, (ii) we will not incur most of these costs for a number of years, requiring us to make estimates over a long period, (iii) calculating the discounted cash flows for certain of our environmental obligations requires management to estimate the amounts and timing of projected cash flows and make long-term assumptions about inflation rates and (iv) changes in

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

estimates used in determining our environmental obligations could have a significant impact on our results of operations.

We perform a comprehensive annual review of our environmental obligations and also review changes in facts and circumstances associated with these obligations at least quarterly. Judgments and estimates are based upon currently available facts, existing technology, presently enacted laws and regulations, remediation experience, whether or not we are a potentially responsible party (PRP), the ability of other PRPs to pay their allocated portions and take into consideration reasonably possible outcomes. Our cost estimates can change substantially as additional information becomes available regarding the nature or extent of site contamination, updated cost assumptions (including increases and decreases to cost estimates), changes in the anticipated scope and timing of remediation activities, the settlement of environmental matters, required remediation methods and actions by or against governmental agencies or private parties.

**Asset Retirement Obligations**

Refer to Notes 1 and 12, and Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, for further discussion of reclamation and closure costs, including a summary of changes in our asset retirement obligations (AROs) for the three years ended December 31, 2022.

We record the fair value of our estimated AROs associated with tangible long-lived assets in the period incurred. Fair value is measured as the present value of cash flow estimates after considering inflation and a market risk premium. Our cost estimates are reflected on a third-party cost basis and comply with our legal obligation to retire tangible long-lived assets in the period incurred. These cost estimates may differ from financial assurance cost estimates for reclamation activities because of a variety of factors, including obtaining updated cost estimates for reclamation activities, the timing of reclamation activities, changes in scope and the exclusion of certain costs not considered reclamation and closure costs. At December 31, 2022, AROs recorded in our consolidated balance sheet totaled $3.0 billion.

Generally, ARO activities are specified by regulations or in permits issued by the relevant governing authority, and management's judgment is required to estimate the extent and timing of expenditures. Accounting for AROs represents a critical accounting estimate because (i) we will not incur most of these costs for a number of years, requiring us to make estimates over a long period, (ii) reclamation and closure laws and regulations could change in the future and/or circumstances affecting our operations could change, either of which could result in significant changes to our current plans, (iii) our implementation of the Global Industry Standard on Tailings Management, which could result in changes to our plans and the scope of work required (iv) the methods used or required to plug and abandon non-producing oil and gas wellbores, remove platforms, tanks, production equipment and flow lines, and restore the wellsite could change, (v) calculating the fair value of our AROs requires management to estimate projected cash flows, make long-term assumptions about inflation rates, determine our credit-adjusted, risk-free interest rates and determine market risk premiums that are appropriate for our operations and (vi) given the magnitude of our estimated reclamation, mine closure and wellsite abandonment and restoration costs, changes in any or all of these estimates could have a significant impact on our results of operations.

**Mineral Reserves** 

Refer to Note 17, Items 1. and 2. "Business and Properties" and Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, for further information regarding, and risks associated with, our estimated recoverable proven and probable mineral reserves.

Recoverable proven and probable mineral reserves were determined from the application of relevant modifying factors to geological data, in order to establish an operational, economically viable mine plan and have been prepared in accordance with the disclosure requirements of Subpart 1300 of Securities and Exchange Commission (SEC) Regulation S-K. The determination of mineral reserves involves numerous uncertainties with respect to the ultimate geology of the ore bodies, including quantities, grades and recoveries. Estimating the quantity and grade of mineral reserves requires us to determine the size, shape and depth of our ore bodies by analyzing geological data, such as samplings of drill holes, tunnels and other underground workings. In addition to the geology of our mines, assumptions are required to determine the economic feasibility of mining these reserves, including estimates of future commodity prices and demand, the mining methods we use and the related costs incurred to develop and mine our mineral reserves. Our estimates of recoverable proven and probable mineral reserves are prepared by and are the responsibility of our employees. These estimates are reviewed and verified regularly by independent experts in mining, geology and reserve determination.

Our consolidated estimated recoverable proven and probable mineral reserves shown below were assessed using long-term price assumptions of $3.00 per pound of copper, $1,500 per ounce of gold and $12 per pound of molybdenum at December 31, 2022, compared with long-term price assumptions of $2.50 per pound of copper, $1,200 per ounce of gold and $10 per pound of molybdenum at December 31, 2021. The following table summarizes changes in our estimated consolidated recoverable proven and probable copper, gold and molybdenum mineral reserves during 2022:

Note: Totals may not foot because of rounding.

a.Includes estimated recoverable metals contained in stockpiles. See below for additional discussion of recoverable copper in stockpiles.

b.Primarily reflects the impact of a higher long-term price assumption for copper at December 31, 2022, compared with December 31, 2021.

As discussed in Note 1, we depreciate our life-of-mine mining and milling assets and values assigned to proven and probable mineral reserves using the unit-of-production (UOP) method based on our estimated recoverable proven and probable mineral reserves. Because the economic assumptions used to estimate mineral reserves may change from period to period and additional geological data is generated during the course of operations, estimates of mineral reserves may change, which could have a significant impact on our results of operations, including changes to prospective depreciation rates and impairments of long-lived asset carrying values. Based on projected copper sales volumes, if estimated copper reserves at our mines were 10% higher at December 31, 2022, we estimate that our annual depreciation, depletion and amortization (DD&A) expense for 2023 would decrease by approximately $106 million (approximately $39 million to net income attributable to common stock), and a 10% decrease in copper reserves would increase DD&A expense by approximately $130 million (approximately $47 million to net income attributable to common stock). We perform annual assessments of our existing assets in connection with the review of mine operating and development plans. If it is determined that assigned asset lives do not reflect the expected remaining period of benefit, any change could affect prospective DD&A rates.

As discussed below and in Note 1, we review and evaluate our long-lived assets for impairment when events or changes in circumstances indicate that the related carrying amount of such assets may not be recoverable, and changes to our estimates of recoverable proven and probable mineral reserves could have an impact on our assessment of asset recoverability.

**Recoverable Copper in Stockpiles** 

Refer to Note 1 for further discussion of our accounting policy for recoverable copper in stockpiles and to Note 4 and "Consolidated Results" for discussion of adjustments to stockpile inventory volumes.

We record, as inventory, applicable costs for copper contained in mill and leach stockpiles that are expected to be processed in the future based on proven processing technologies. Mill and leach stockpiles are evaluated periodically to ensure that they are stated at the lower of weighted-average cost or net realizable value (NRV).

Accounting for recoverable copper from mill and leach stockpiles represents a critical accounting estimate because (i) it is impracticable to determine copper contained in mill and leach stockpiles by physical count, thus requiring management to employ reasonable estimation methods and (ii) recoveries from leach stockpiles can vary significantly.

At December 31, 2022, estimated consolidated recoverable copper was 1.8 billion pounds in leach stockpiles (with a carrying value of $2.2 billion) and 0.3 billion pounds in mill stockpiles (with a carrying value of $0.4 billion).

**Impairment of Long-Lived Assets** 

As discussed in Note 1, we assess the carrying values of our long-lived mining assets when events or changes in circumstances indicate that the related carrying amounts of such assets may not be recoverable. In evaluating our long-lived mining assets for recoverability, we use estimates of pre-tax undiscounted future cash flows of our mines.

Estimates of future cash flows are derived from current business plans, which are developed using near-term metal price forecasts reflective of the current price environment and management's projections for long-term average metal prices. In addition to near- and long-term metal price assumptions, other key assumptions include estimates of commodity-based and other input costs; proven and probable mineral reserves estimates, including the timing and cost to develop and produce the mineral reserves; value beyond proven and probable mineral reserve estimates; and the use of appropriate discount rates in the measurement of fair value. We believe our estimates and models used to determine fair value are similar to what a market participant would use. As quoted market prices are unavailable for our individual mining operations, fair value is determined through the use of after-tax discounted estimated future cash flows.

During the two-year period ended December 31, 2022, no material impairments of our long-lived mining assets were recorded.

In addition to decreases in future metal price assumptions, other events that could result in future impairment of our long-lived mining assets include, but are not limited to, decreases in estimated recoverable proven and probable mineral reserves and any event that might otherwise have a material adverse effect on mine site production levels or costs. Refer to Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022.

**Revenues**

Consolidated revenues totaled $22.8 billion in both 2022 and 2021. Our revenues primarily include the sale of copper concentrate, copper cathode, copper rod, gold in concentrate and molybdenum. Following is a summary of changes in our consolidated revenues from 2021 to 2022 (in millions):

<u>Sales Volumes</u>. Copper and gold sales volumes were higher in 2022, compared to 2021, primarily reflecting increased operating rates at the Grasberg minerals district and Cerro Verde. Refer to "Operations" for further discussion of sales volumes at our mining operations.

<u>Realized Prices</u>. Our consolidated revenues can vary significantly as a result of fluctuations in the market prices of copper, gold and molybdenum. In 2022, our average realized prices, compared with 2021, were 10% lower for copper, 1% lower for gold and 20% higher for molybdenum.

As discussed in "Disclosures About Market Risks - Commodity Price Risk," substantially all of our copper concentrate and cathode sales contracts provide final copper pricing in a specified future month (generally one to

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

four months from the shipment date). We record revenues and invoice customers at the time of shipment based on then-current LME prices, which results in an embedded derivative on provisionally priced concentrate and cathode sales that is adjusted to fair value through earnings each period, using the period-end forward prices, until final pricing on the date of settlement. To the extent final prices are higher or lower than what was recorded on a provisional basis, an increase or decrease to revenues is recorded each reporting period until the date of final pricing. Accordingly, in times of rising copper prices, our revenues benefit from adjustments to the final pricing of provisionally priced sales pursuant to contracts entered into in prior periods; in times of falling copper prices, the opposite occurs.

Consolidated revenues include net (unfavorable) favorable adjustments to current year provisionally priced copper sales (*i.e.,* provisionally priced sales during the years 2022 and 2021) totaling $(539) million for 2022 and $256 million for 2021. Refer to Note 14 for a summary of total adjustments to prior period and current period provisionally priced sales.

<u>Prior Year Provisionally Priced Copper Sales</u>. Net favorable adjustments to prior years' provisionally priced copper sales (*i.e.,* provisionally priced copper sales at December 31, 2021 and 2020) recorded in consolidated revenues totaled $60 million in 2022 and $169 million in 2021. Refer to "Disclosures About Market Risks - Commodity Price Risk" for further discussion of our provisionally priced copper sales, and to Note 14 for a summary of total adjustments to prior period and current period provisionally priced copper sales.

<u>Purchased Copper</u>. Lower revenues associated with purchased copper in 2022 compared to 2021, primarily reflects lower volumes and prices. We purchased copper cathode primarily for processing by our Rod & Refining operations, totaling 124 million pounds in 2022 and 173 million pounds in 2021.

<u>Atlantic Copper Revenues</u>. Lower Atlantic Copper revenues in 2022, compared with 2021, primarily reflect reduced operations as a result of a scheduled major maintenance turnaround resulting in a 78-day shutdown and lower copper prices.

<u>Treatment Charges</u>. Revenues from our concentrate sales are recorded net of treatment charges (*i.e.,* fees paid to smelters that are generally negotiated annually), which will vary with the sales volumes and the price of copper. The increase in the treatment charges during 2022 primarily reflects higher copper sales volumes.

<u>Royalties and Export Duties</u>. Royalties are primarily on PT-FI sales and vary with the volume of metal sold and the prices of copper and gold. In late 2022, PT-FI's export duty rate declined from 5% to 2.5% as a result of smelter development progress. Higher royalties and export duties during 2022, compared to 2021, are primarily associated with increased copper and gold sales volumes, partly offset by the decline in metal prices. Refer to "Operations - Indonesia Mining" for further discussion of the current progress on additional smelting capacity in Indonesia and to Note 13 for a summary of PT-FI's royalties and export duties.

**Production and Delivery Costs**

Consolidated production and delivery costs totaled $13.0 billion in 2022, compared with $12.0 billion in 2021. Higher consolidated production and delivery costs in 2022 are primarily associated with significant inflationary cost pressures, principally associated with materials and supplies including sulfuric acid and explosives (41% of our site operating costs), labor (27% of our site operating costs) and energy prices (21% of our site operating costs). During 2022, prices for a number of commodity-related consumables increased at a time when copper prices declined. While prices for a number of commodity-related consumables have retreated from the highs of 2022, most cost elements remain high relative to long-term correlations.

Consolidated production and delivery costs also includes net charges totaling $157 million in 2022, primarily associated with ARO adjustments and an administrative fine at PT-FI; and $415 million in 2021, primarily associated with ARO adjustments and other net charges at PT-FI and nonrecurring labor-related costs at Cerro Verde for collective labor agreements, partly offset by refunds of Arizona transaction privilege taxes related to purchased electricity and favorable adjustments to prior-years' profit sharing at Cerro Verde. Refer to Note 16 for details of production and delivery costs by operating segment.

<u>Mining Unit Site Production and Delivery Costs</u>. Site production and delivery costs for our copper mining operations primarily include labor, energy and commodity-based inputs, such as sulfuric acid, reagents, liners, tires and explosives. Consolidated unit site production and delivery costs (before net noncash and other costs) for our copper mines averaged $2.19 per pound of copper in 2022 and $1.93 per pound in 2021. Higher consolidated unit site

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

production and delivery costs in 2022, compared with 2021, primarily reflect higher energy prices and increased costs for consumables such as sulfuric acid, explosives, key equipment parts and other supplies and services. Refer to "Operations - Unit Net Cash Costs" for further discussion of unit net cash costs associated with our operating divisions, and to "Product Revenues and Production Costs" for reconciliations of per pound costs by operating division to production and delivery costs applicable to sales reported in our consolidated financial statements.

Our copper mining operations require significant amounts of energy, principally diesel, electricity, coal and natural gas, most of which is obtained from third parties under long-term contracts. Our take-or-pay contractual obligations for electricity totaled approximately $0.3 billion at December 31, 2022. We do not have take-or-pay contractual obligations for other energy commodities. Energy represented approximately 21% of our copper mine site operating costs in 2022, including purchases of approximately 230 million gallons of diesel fuel; approximately 8,400 gigawatt hours of electricity at our North America and South America copper mining operations (we generate all of our power at our Indonesia mining operation); approximately 820 thousand metric tons of coal for our coal power plant in Indonesia; and approximately 1 million MMBtu (million British thermal units) of natural gas at certain of our North America mines. Based on current cost estimates, energy will approximate 24% of our copper mine site operating costs for 2023.

**Depreciation, Depletion and Amortization** 

Depreciation will vary under the UOP method as a result of changes in sales volumes and the related UOP rates at our mining operations. Consolidated DD&A totaled $2.0 billion in both 2022 and 2021.

**Metals Inventory Adjustments**

Unfavorable metals inventory adjustments totaled $29 million in 2022 and $16 million in 2021. Adjustments in 2022 reflect NRV inventory adjustments related to lower market prices for copper and higher costs at Morenci and Bagdad. Adjustments in 2022 also include $10 million for stockpile write-offs at Cerro Verde. Adjustments in 2021 were primarily related to a leach stockpile adjustment at Morenci.

**Environmental Obligations and Shutdown Costs**

Environmental obligation costs reflect net revisions to our long-term environmental obligations, which vary from period to period because of changes to environmental laws and regulations, the settlement of environmental matters and/or circumstances affecting our operations that could result in significant changes in our estimates (refer to "Critical Accounting Estimates - Environmental Obligations" for further discussion). Shutdown costs include care-and-maintenance costs and any litigation, remediation or related expenditures associated with closed facilities or operations.

Net charges for environmental obligations and shutdown costs totaled $121 million in 2022, including $44 million for a proposed settlement related to historical environmental litigation and $22 million in net unfavorable adjustments to environmental obligations. Net charges for the year 2021 totaled $91 million, including net unfavorable adjustments to environmental obligations totaling $41 million. Refer to Note 12 for further discussion of environmental obligations and litigation matters.

**Net Gain on Sales of Assets** 

Net gain on sales of assets totaled $2 million in 2022 and $80 million in 2021. Gains on sales of assets in 2021 were primarily associated with the sale of our remaining Freeport Cobalt assets and the sale of carbon dioxide emissions credits at Atlantic Copper. Refer to Note 2 for further discussion of dispositions.

**Net Gain on Early Extinguishment of Debt**

Net gain on early extinguishment of debt totaled $31 million in 2022, consisting primarily of $44 million associated with senior note purchases, partly offset by a charge of $10 million associated with the repayment of the PT-FI term loan. Refer to Note 8 for further discussion.

**Interest Expense, Net**

Consolidated interest costs (before capitalization) totaled $710 million in 2022 and $674 million in 2021. Higher interest costs (before capitalization) in 2022, compared with 2021, primarily reflects additional interest costs associated with PT-FI senior notes sold in April 2022, partly offset by lower interest costs associated with the repayment and purchase of certain FCX senior notes. Refer to Note 8 for further discussion.

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

Capitalized interest varies with the level of expenditures for our development projects and average interest rates on our borrowings and totaled $150 million in 2022 and $72 million in 2021. The increase in capitalized interest in 2022, compared with 2021, is primarily associated with development activities related to Indonesia smelter projects. Refer to "Operations" and "Capital Resources and Liquidity - Investing Activities" for further discussion of current development projects.

**Other Income (Expense), Net** 

Other income (expense), net, totaled $207 million in 2022 and $(105) million in 2021. The year 2022 primarily includes interest income totaling $136 million and credits totaling $76 million associated with favorable adjustments to penalties on historical contested tax matters. The year 2021 primarily includes charges totaling $208 million associated with historical contested tax matters at PT-FI, partly offset by gains on currency exchange rate movements and other net credits. Refer to Note 11 for discussion of historical tax matters.

**Income Taxes**

Following is a summary of the approximate amounts used in the calculation of our consolidated income tax provision for the years ended December 31 (in millions, except percentages):

a.Represents income before income taxes and equity in affiliated companies' net earnings.

b.In addition to our North America mining operations, the U.S. jurisdiction reflects corporate-level expenses, which include interest expense associated with senior notes, general and administrative expenses, and environmental obligations and shutdown costs.

c.Includes valuation allowance release on prior year unbenefited NOLs.

d.Includes a tax benefit of $31 million ($16 million net of noncontrolling interest), primarily associated with completion of Cerro Verde's 2016 tax audit.

e.Includes a tax benefit of $18 million ($9 million net of noncontrolling interest), primarily associated with completion of tax audits at Cerro Verde for the years 2014 and 2015.

f.Includes net tax benefits associated with the release of valuation allowances recorded against PT Rio Tinto Indonesia NOLs totaling $189 million ($151 million net of noncontrolling interest).

In August 2022, the Act was signed into law, which includes, among other provisions, a new CAMT of 15% on the adjusted financial statement income (AFSI) of corporations with average AFSI exceeding $1.0 billion over a three-year period, and a new excise tax of 1% on the fair market value of net corporate stock repurchases. The Act had no impact on our consolidated financial statements for the year ended December 31, 2022. The provisions of the Act are applicable to us beginning January 1, 2023. Additional guidance related to how the CAMT provisions of the Act will be applied or otherwise administered is yet to be released by the U.S. Department of the Treasury, and may differ from our interpretations. We will continue to analyze the impacts as additional guidance is available. We expect the CAMT provisions will impact our U.S. tax position, and may further limit our ability to benefit from our U.S. NOLs.

Assuming achievement of current sales volume and cost estimates and average prices of $4.00 per pound for copper, $1,900 per ounce for gold and $20.00 per pound for molybdenum for 2023, we estimate our consolidated effective tax rate for the year 2023 would approximate 33%. Changes in projected sales volumes and average prices during 2023 would incur tax impacts at estimated effective rates of 39% for Peru, 38% for Indonesia and 0% for the U.S., which excludes any potential impact from the Act. Our projected estimated effective tax rate of 0% for the U.S. for the year 2023 may be adjusted as additional guidance is released by the U.S. Department of the Treasury on key provisions of the Act, including guidance on the CAMT.

**OPERATIONS**

**Responsible Production**

<u>The Copper Mark</u>. We are committed to maintaining the validation of all of our copper producing sites with the Copper Mark, a comprehensive assurance framework designed to demonstrate the copper industry's responsible production practices. To achieve the Copper Mark, each site is required to complete an external assurance process to assess conformance with 32 environmental, social and governance (ESG) requirements. In February 2023, PT-FI was awarded the Copper Mark and we have now achieved the Copper Mark at all 12 of our eligible copper producing sites globally.

In fourth-quarter 2022, the Copper Mark announced an extension of its framework to include molybdenum producers, among other metal producers. In February 2023, our Climax and Henderson molybdenum mines were awarded the Molybdenum Mark, making FCX the first molybdenum miner to achieve this distinction. Our four copper mines that produce byproduct molybdenum (Bagdad, Cerro Verde, Morenci and Sierrita) have also been awarded the Molybdenum Mark.

<u>ICMM</u>. We are a founding member of the International Council on Mining & Metals (ICMM), an organization dedicated to a safe, fair and sustainable mining and metals industry, aiming continuously to strengthen ESG performance across the global mining and metals industry. As a member company, we are required to implement the 10 Mining Principles that define good ESG practices, and associated position statements, while also meeting 39 performance expectations and producing an externally verified sustainability report in accordance with the Global Reporting Initiative Sustainability Reporting Standards subject to the ICMM Assurance & Validation Procedure.

<u>2021 Annual Report on Sustainability</u>. In April 2022, we published our 2021 Annual Report on Sustainability, which is available on our website at fcx.com/sustainability. We have a long history of ESG programs, and we are focused on leading as a responsible copper producer. Refer to Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, for discussion of ESG-related risks.

<u>2021 Climate Report</u>. In September 2022, we published our updated Climate Report which details our ongoing initiatives to reduce our greenhouse gas (GHG) emissions, improve energy efficiency, evaluate and integrate the use of lower carbon and renewable energy sources and enhance our resilience to future climate-related risks. We continue to advance GHG emissions reduction initiatives across our global operations and established our 2030 GHG reduction targets that collectively cover nearly 100% of our Scope 1 and 2 GHG emissions. Refer to Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, for further discussion of climate-related risks.

**Leaching Innovation Initiatives** 

We are advancing efforts to improve copper recovery from our leach processes, including initiatives across our North America and South America operations to incorporate new applications, technologies and data analytics. We believe these leach innovation initiatives provide potential opportunities to produce incremental copper from our large existing leach stockpiles and lower-grade material currently classified as waste. Initial results support the potential for incremental low-cost additions to our production and reserve profile and we have identified opportunities to achieve an annual run rate of 200 million pounds of copper per year through these initiatives by the end of 2023.

**Feasibility and Optimization Studies**

We are engaged in various studies associated with potential future expansion projects primarily at our mining operations. The costs for these studies are charged to production and delivery costs as incurred and totaled $141 million for 2022 and $59 million for 2021. We estimate the costs of these studies will approximate $200 million for the year 2023 (including approximately $70 million in first-quarter 2023).

**North America Copper Mines**

We operate seven open-pit copper mines in North America - Morenci, Bagdad, Safford (including Lone Star), Sierrita and Miami in Arizona, and Chino and Tyrone in New Mexico. All of the North America mining operations are wholly owned, except for Morenci. We record our 72% undivided joint venture interest in Morenci using the proportionate consolidation method.

The North America copper mines include open-pit mining, sulfide-ore concentrating, leaching and solution extraction/electrowinning (SX/EW) operations. A majority of the copper produced at our North America copper mines is cast into copper rod by our Rod & Refining segment. The remainder of our North America copper production is sold as copper cathode or copper concentrate, a portion of which is shipped to Atlantic Copper (our wholly owned smelter). Molybdenum concentrate, gold and silver are also produced by certain of our North America copper mines*.* 

<u>Operating and Development Activities</u>. We have substantial reserves and future opportunities in the U.S., primarily associated with existing mining operations.

Following our response to the COVID-19 pandemic in early 2020, we began ramping up mining rates at the North America mines during 2021, which continued into 2022. However, a tight labor market and increased competition from other employers in North America represent strategic challenges that are impacting our ability to further expand current mining rates.

Lone Star, at our Safford mine, is increasing its operating rates to achieve targeted production of approximately 300 million pounds of copper per year from oxide ores in 2023 (compared with the initial design capacity of 200 million pounds of copper per year). The oxide project at Lone Star advances the opportunity for development of the underlying, large-scale sulfide resources. We are conducting follow-on exploration in the area to support metallurgical testing and mine development planning for a potential significant long-term investment to build additional scale on an economically attractive basis.

We are planning an expansion to double the concentrator capacity of the Bagdad operation in northwest Arizona. We are engaging stakeholders and conducting a feasibility study, which is expected to be completed in 2023. We are advancing plans for expanded tailings infrastructure projects to support Bagdad's long-range plans. The timing of future development will be dependent on market conditions, labor and supply chain considerations and other economic factors.

Our North America copper mines have varying cost structures because of differences in ore grades and characteristics, processing costs, by-product credits and other factors. During 2022, our mining operations experienced significant cost inflation, principally associated with higher energy, labor, maintenance and supplies, explosives and sulfuric acid, resulting in higher average unit net cash costs (net of by-product credits) for the North America copper mines of $2.35 per pound of copper in 2022, compared with $1.89 per pound of copper in 2021. However, average unit net cash costs for our North America copper mines in 2022, compared with 2021, benefited from higher sales volumes.

Because certain assets are depreciated on a straight-line basis, North America's average unit depreciation rate may vary with asset additions and the level of copper production and sales.

Revenue adjustments primarily result from changes in prices on provisionally priced copper sales recognized in prior periods. Refer to "Consolidated Results – Revenues" for further discussion of adjustments to prior period provisionally priced copper sales.

Average unit net cash costs (net of by-product credits) for our North America copper mines are expected to approximate $2.45 per pound of copper in 2023, based on achievement of current sales volume and cost estimates and assuming an average molybdenum price of $20.00 per pound. North America's expected average unit net cash costs for the year 2023 would change by approximately $0.03 per pound for each $2 per pound change in the average price of molybdenum.

**South America Mining**

We operate two copper mines in South America - Cerro Verde in Peru (in which we own a 53.56% interest) and El Abra in Chile (in which we own a 51.0% interest), which are consolidated in our financial statements.

South America mining includes open-pit mining, sulfide-ore concentrating, leaching and SX/EW operations. Production from our South America mines is sold as copper concentrate or cathode under long-term contracts. Our South America mines also sell a portion of their copper concentrate production to Atlantic Copper. In addition to copper, the Cerro Verde mine produces molybdenum concentrate and silver.

Beginning in late 2022, heightened tensions, protests and social unrest emerged in Peru following a change in the country's political leadership. Demonstrations have continued in early 2023, and the civil unrest continues to disrupt commerce and supply chains in Peru. To date, there has been a limited impact on Cerro Verde's operations. We continue to monitor the situation while prioritizing safety and security. A prolonged disruption of logistics and supply chains could impact future operations.

<u>Operating and Development Activities</u>. Increased operating rates at Cerro Verde and higher mining and stacking activities at El Abra resulted in a 12% increase in copper production from South America mining for the year 2022, compared with the year 2021 (which was impacted by COVID-19 protocols).

El Abra's large sulfide resource supports a potential major mill project similar to the large-scale concentrator constructed at Cerro Verde in 2015. Technical and economic studies continue to be evaluated to determine the optimal scope and timing for the sulfide project. We are advancing plans to invest in water infrastructure to provide options to extend existing operations, while continuing to monitor potential changes in Chile's regulatory and fiscal matters. We will defer major investment decisions pending clarity on such matters.

a.Includes charges totaling $0.09 per pound of copper associated with nonrecurring labor-related costs at Cerro Verde.

Our South America mines have varying cost structures because of differences in ore grades and characteristics, processing costs, by-product credits and other factors. During 2022, our mining operations experienced significant cost inflation, principally associated with higher energy, sulfuric acid, explosives and other input costs, resulting in higher average unit net cash costs (net of by-product credits) for South America mining of $2.34 per pound of copper in 2022, compared with $2.05 per pound of copper in 2021. However, average unit net cash costs for South America mining in 2022, compared with 2021, benefited from higher sales volumes.

Revenues from Cerro Verde's concentrate sales are recorded net of treatment charges, which will vary with Cerro Verde's sales volumes and the price of copper.

Because certain assets are depreciated on a straight-line basis, South America's unit depreciation rate may vary with asset additions and the level of copper production and sales.

Revenue adjustments primarily result from changes in prices on provisionally priced copper sales recognized in prior periods. Refer to "Consolidated Results - Revenues" for further discussion of adjustments to prior period provisionally priced copper sales.

**Indonesia Mining**

PT-FI operates one of the world's largest copper and gold mines at the Grasberg minerals district in Central Papua, Indonesia. PT-FI produces copper concentrate that contains significant quantities of gold and silver. We have a 48.76% ownership interest in PT-FI and manage its mining operations. PT-FI's results are consolidated in our financial statements.

As discussed in Note 3, under the terms of the divestment agreement and related documents entered into in 2018, our economic interest in PT-FI approximated 81% through 2022, and beginning January 1, 2023, our economic interest in PT-FI is 48.76%. This arrangement was developed to replicate the economics of PT-FI's former joint venture partner interests, which were acquired by the Indonesia government in 2018.

Substantially all of PT-FI's copper concentrate is sold under long-term contracts. During 2022, 34% of PT-FI's copper concentrate was sold to PT Smelting (PT-FI's 39.5% owned copper smelter and refinery in Gresik, Indonesia). See "Smelting and Refining" below for a discussion of PT-FI's tolling arrangement with PT Smelting that commenced in 2023.

<u>Operating and Development Activities</u>. PT-FI currently has three underground operating mines in the Grasberg minerals district: Grasberg Block Cave, Deep Mill Level Zone (DMLZ) and Big Gossan.

PT-FI's milling rates for ore extracted from its underground mines averaged 192,600 metric tons of ore per day in 2022. The installation of additional milling facilities at PT-FI is currently expected to be completed in late 2023, which would increase milling capacity to approximately 240,000 metric tons of ore per day to provide for continued annualized copper and gold production volumes of approximately 1.6 billion pounds of copper and 1.6 million ounces of gold. PT-FI is also advancing a mill recovery project with the installation of a new copper cleaner circuit that is expected to be completed in 2024, which is expected to provide incremental metal production of approximately 60 million pounds of copper and 40 thousand ounces of gold per year.

<u>Kucing Liar</u>. Long-term mine development activities are ongoing for PT-FI's Kucing Liar deposit in the Grasberg minerals district, which is expected to produce over 6 billion pounds of copper and 6 million ounces of gold between 2028 and the end of 2041. Pre-production development activities commenced in 2022 and are expected to continue over an approximate 10-year timeframe. Capital investments are estimated to average approximately $400 million per year over this period (including approximately $470 million for the year 2023). At full operating rates of approximately 90,000 metric tons of ore per day, annual production from Kucing Liar is expected to approximate 550 million pounds of copper and 560 thousand ounces of gold, providing PT-FI with sustained long-term, large-scale and low-cost production. Kucing Liar will benefit from substantial shared infrastructure and PT-FI's experience and long-term success in block-cave mining.

<u>Indonesia Smelter</u>. In connection with PT-FI's 2018 agreement with the Indonesia government to secure the extension of its long-term mining rights, PT-FI committed to construct additional domestic smelting capacity totaling 2 million dry metric tons of concentrate per year by the end of 2023 (subject to force majeure provisions). In accordance with Indonesia regulations, PT-FI submits a smelter progress report to the Indonesia government for review every six months (refer to Note 12).

PT-FI is actively engaging in the following projects for additional domestic smelting capacity:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*•* Construction of a greenfield smelter in Gresik, Indonesia with a capacity to process approximately 1.7 million metric tons of copper concentrate per year. At December 31, 2022, smelter construction was approximately 50% complete. The facility is expected to be commissioned during 2024 at an estimated cost of $3.0 billion, including $2.8 billion for a construction contract (excluding capitalized interest, owner's costs and commissioning) and $0.2 billion for investment in a desalinization plant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Expansion of PT Smelting's capacity by 30% to 1.3 million metric tons of copper concentrate per year, which is expected to be completed by the end of 2023. PT-FI is funding the cost of the expansion, estimated to approximate $250 million, with a loan that will convert to equity, increasing PT-FI's ownership in PT Smelting upon project completion (refer to Note 3).

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*•* Construction of a PMR to process gold and silver from the greenfield smelter and PT Smelting at an estimated cost of $400 million. Construction is in progress with commissioning expected during 2024.

Capital expenditures for the Indonesia smelter projects totaled $0.8 billion for the year 2022 and are expected to approximate $1.8 billion for the year 2023. Capital expenditures for the Indonesia smelter projects are being funded with proceeds received from PT-FI's April 2022 senior notes offering and availability under its revolving credit facility.

Construction of the additional domestic smelter capacity will result in the elimination of export duties, which mitigates the economic cost associated with the Indonesia smelter projects. In late 2022, PT-FI received approval, based on construction progress achieved, for a reduction in export duties from 5% to 2.5%. Upon receiving verification and approval from the Indonesia government that construction progress has exceeded 50%, PT-FI expects export duties to be eliminated.

Indonesia regulations require PT-FI to renew its export license annually, subject to review by the Indonesia government every six months, depending on, among other things, greenfield smelter construction progress. The current license is scheduled for renewal in March 2023 and PT-FI is preparing its renewal application. PT-FI's special mining license (IUPK) provides that exports continue through 2023, subject to force majeure considerations. PT-FI plans to work cooperatively with the Indonesia government to continue exports beyond 2023 as required until the smelter is fully commissioned. Refer to Note 12 and Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, for further discussion of risks associated with PT-FI's export of copper concentrate.

<u>Mining Rights</u>. PT-FI and the Indonesia government continue to engage in preliminary discussions regarding the extension of PT-FI's mining rights under its IUPK beyond 2041. PT-FI believes an extension beyond 2041 would enable continuity of operations and the identification of additional resource development opportunities in the Grasberg minerals district. Refer to Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, for further discussion of risks associated with PT-FI's IUPK.

Higher consolidated sales of 1.6 billion pounds of copper and 1.8 million ounces of gold in 2022, compared with 1.3 billion pounds of copper and 1.3 million ounces of gold in 2021, primarily reflect increased operating rates at the Grasberg minerals district, partly offset by lower copper ore grades. Consolidated sales volumes from PT-FI are expected to approximate 1.5 billion pounds of copper and 1.7 million ounces of gold in 2023, net of approximately 90 million pounds of copper and 120 thousand ounces of gold from mine production in concentrate form that will be deferred until sale in the form of refined metal under the tolling agreement with PT Smelting.

<u>Unit Net Cash Costs</u>. Unit net cash costs per pound of copper is a measure intended to provide investors with information about the cash-generating capacity of our mining operations expressed on a basis relating to the primary metal product for our respective operations. We use this measure for the same purpose and for monitoring operating performance by our mining operations. This information differs from measures of performance determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for measures of performance determined in accordance with U.S. GAAP. This measure is presented by other metal mining companies, although our measure may not be comparable to similarly titled measures reported by other companies.

*Gross Profit per Pound of Copper and per Ounce of Gold*

a.Includes charges associated with ARO adjustments totaling $0.07 per pound of copper in 2022 and $0.26 per pound of copper in 2021.

A significant portion of PT-FI's costs are fixed and unit costs vary depending on volumes and other factors. PT-FI's unit net cash costs (including gold and silver credits) of $0.09 per pound of copper in 2022, were lower than unit net cash costs of $0.19 per pound of copper in 2021, primarily reflecting higher copper and gold sales volumes, partly offset by higher energy costs and the impact of increased operating rates.

Treatment charges vary with the volume of metals sold and the price of copper, and royalties vary with the volume of metals sold and the prices of copper and gold.

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

PT-FI's export duties totaled $307 million in 2022 and $218 million in 2021, and PT-FI's royalties totaled $357 million in 2022 and $319 million in 2021. The increase in export duties and royalties in 2022, compared with 2021, primarily reflects higher sales volumes. As noted above, in late 2022, PT-FI's export duty rate declined from 5% to 2.5%. Refer to Note 13 for further discussion of PT-FI's export duties and royalties.

Because certain assets are depreciated on a straight-line basis, PT-FI's unit depreciation rate may vary with asset

additions and the level of copper production and sales. The decrease in the DD&A rate per pound of copper in 2022, compared with 2021, primarily reflects higher volumes associated with increased operating rates and the depletion of the DOZ underground mine during 2021, partly offset by significant underground development assets being placed into service.

Revenue adjustments primarily result from changes in prices on provisionally priced copper sales recognized in prior periods. Refer to "Consolidated Results - Revenues" for further discussion of adjustments to prior period provisionally priced copper sales.

PT Smelting intercompany profit (loss) represents the change in the deferral of 39.5% of PT-FI's profit on

sales to PT Smelting. Refer to "Smelting and Refining" below for further discussion.

Assuming an average gold price of $1,900 per ounce for 2023 and achievement of current sales volume and cost estimates, unit net cash costs (including gold and silver credits) for PT-FI are expected to approximate $0.22 per pound of copper in 2023. PT-FI's expected average unit net cash costs for the year 2023 would change by approximately $0.10 per pound of copper for each $100 per ounce change in the average price of gold.

PT-FI's projected sales volumes and unit net cash costs for the year 2023 are dependent on a number of factors, including operational performance, weather-related conditions, timing of shipments and the Indonesia government's extension of PT-FI's export permit. Refer to "Cautionary Statement" below and Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, for further discussion of factors that could cause results to differ materially from projections, including the February 2023 weather event at PT-FI's operations.

**Molybdenum Mines** 

We have two wholly owned molybdenum mines in Colorado - the Henderson underground mine and the Climax open-pit mine. The Henderson and Climax mines produce high-purity, chemical-grade molybdenum concentrate, which is typically further processed into value-added molybdenum chemical products. The majority of the molybdenum concentrate produced at the Henderson and Climax mines, as well as from our North America and South America copper mines, is processed at our own conversion facilities.

<u>Operating and Development Activities</u>. Production from the Molybdenum mines totaled 33 million pounds of molybdenum in 2022 and 30 million pounds in 2021. Refer to "Consolidated Results" for our consolidated molybdenum operating data, which includes sales of molybdenum produced at our Molybdenum mines and from our North America and South America copper mines. Refer to "Outlook" for projected consolidated molybdenum sales volumes.

<u>Unit Net Cash Costs Per Pound of Molybdenum</u>. Unit net cash costs per pound of molybdenum is a measure intended to provide investors with information about the cash-generating capacity of our mining operations expressed on a basis relating to the primary metal product for our respective operations. We use this measure for the same purpose and for monitoring operating performance by our mining operations. This information differs from measures of performance determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for measures of performance determined in accordance with U.S. GAAP. This measure is presented by other metals mining companies, although our measure may not be comparable to similarly titled measures reported by other companies.

Average unit net cash costs for our Molybdenum mines of $11.43 per pound of molybdenum in 2022 were higher than $8.87 per pound of molybdenum in 2021, primarily reflecting increased contract labor and higher energy and other input costs, partly offset by higher molybdenum production. Based on current sales volume and cost estimates, average unit net cash costs for the Molybdenum mines are expected to approximate $13.80 per pound of molybdenum in 2023.

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

Refer to "Product Revenues and Production Costs" for a reconciliation of unit net cash costs per pound to production and delivery costs applicable to sales reported in our consolidated financial statements.

**Smelting & Refining**

We wholly own and operate the Miami smelter in Arizona, the El Paso refinery in Texas and Atlantic Copper, a

smelter and refinery in Spain. Additionally, PT-FI has a 39.5% ownership interest in PT Smelting (refer to Note 3).

Treatment charges for smelting and refining copper concentrate consist of a base rate per pound of copper and per ounce of gold and are generally fixed. Treatment charges represent a cost to our mining operations and income to Atlantic Copper. Thus, higher treatment charges benefit the smelter operations and adversely affect our mining operations. Our North America copper mines are less significantly affected by changes in treatment charges because these operations are largely integrated with our Miami smelter and El Paso refinery. Through this form of downstream integration, we are able to assure placement of a significant portion of our concentrate production.

<u>Miami Smelter</u>. In 2021, our Miami smelter completed a major maintenance turnaround and incurred maintenance charges and idle facility costs totaling $87 million. Major maintenance turnarounds are anticipated to occur approximately every two or three years for the Miami smelter. The next major maintenance turnaround is scheduled for the last half of 2024.

<u>Atlantic Copper</u>. Atlantic Copper smelts and refines copper concentrate and markets refined copper and precious metals in slimes. Following is an allocation of Atlantic Copper's concentrate purchases from unaffiliated third parties and our copper mining operations for the years ended December 31:

---

| | | |
|:---|:---|:---|
| | 2022 | 2021 |
| Third parties | 65% | 66% |
| Indonesia mining | 18 | 9 |
| South America mining | 10 | 7 |
| North America copper mines | 7 | 18 |
|  | 100% | 100% |

---

In 2022, Atlantic Copper completed a 78-day major maintenance turnaround and incurred maintenance charges and idle facility costs totaling $41 million. Atlantic Copper's major maintenance turnarounds typically occur approximately every eight years, with shorter-term maintenance turnarounds in the interim.

At December 31, 2022, Atlantic Copper had take-or-pay contractual obligations for the procurement of copper concentrate totaling $3.6 billion, which provide for deliveries of specified volumes at market-based prices.

<u>PT Smelting</u>. Prior to 2023, PT-FI's contract with PT Smelting provided for PT-FI to supply 100% of the copper concentrate requirements (subject to a minimum or maximum treatment charge rate) necessary for PT Smelting to produce 205,000 metric tons of copper annually on a priority basis. PT-FI could also then sell copper concentrate to PT Smelting at market rates for quantities in excess of 205,000 metric tons of copper annually.

Beginning in 2023, PT-FI's commercial arrangement with PT Smelting converted to a tolling arrangement. Under the arrangement, PT-FI pays PT Smelting a tolling fee to smelt and refine its concentrate and will retain title of all products for sale to third parties. This arrangement is not expected to result in a significant change in PT-FI's economics but will impact the timing of PT-FI's sales during 2023. We estimate that approximately 90 million pounds of copper and 120 thousand ounces of gold from PT-FI's first-quarter 2023 production will remain in inventory until final sale later in 2023.

PT Smelting received a one-year extension of its anode slimes export license, which currently expires November 3, 2023. Refer to Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, for further discussion of risks associated with PT Smelting's export of anode slimes.

PT Smelting's maintenance turnarounds (which range from two weeks to a month to complete) typically are expected to occur approximately every two years, with short-term maintenance turnarounds in the interim. PT Smelting completed a 30-day maintenance turnaround during December 2020 and an 18-day maintenance turnaround in October 2022. PT Smelting has a planned 75-day shutdown scheduled for mid-2023 associated with its expansion project and a 7-day shutdown scheduled in fourth-quarter 2023 to complete final tie-in of the expansion project.

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

We defer recognizing profits on sales from our mining operations to Atlantic Copper and on 39.5% of PT-FI's sales to PT Smelting until final sales to third parties occur. Changes in these deferrals attributable to variability in intercompany volumes resulted in net additions (reductions) to operating income totaling $52 million ($33 million to net income attributable to common stock) in 2022 and $(188) million ($(106) million to net income attributable to common stock) in 2021. Our net deferred profits on our inventories at Atlantic Copper and PT Smelting to be recognized in future periods' operating income totaled $250 million at December 31, 2022. Quarterly variations in ore grades, the timing of intercompany shipments and changes in product prices will result in variability in our net deferred profits and quarterly earnings. As noted above, beginning in 2023, PT-FI's commercial arrangement with PT Smelting converted to a tolling arrangement. Under the arrangement, PT-FI pays PT Smelting a tolling fee to smelt and refine its concentrate and will retain title to all products for sale to third parties (*i.e.,* there are no further sales from PT-FI to PT Smelting).

**CAPITAL RESOURCES AND LIQUIDITY**

Our consolidated operating cash flows vary with sales volumes; prices realized from copper, gold and molybdenum sales; production costs; income taxes; other working capital changes; and other factors. See "Consolidated Results" and Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, for further discussion of our energy requirements and related costs.

We believe the actions we have taken in recent years to build a solid balance sheet, successfully expand low-cost operations and maintain flexible organic growth options while maintaining sufficient liquidity, will allow us to continue to execute our business plans in a prudent manner during periods of economic uncertainty while preserving substantial future asset values. We closely monitor market conditions and will adjust our operating plans to protect liquidity and preserve our asset values, if necessary. We expect to maintain a solid balance sheet and strong liquidity position as we focus on building long-term value in our business, executing our operating plans safely, responsibly and efficiently, and prudently managing costs and capital expenditures.

Based on current sales volume, cost and metal price estimates discussed in "Outlook", our available cash and cash equivalents plus our projected consolidated operating cash flows of $7.2 billion for the year 2023 exceed our expected consolidated capital expenditures of $5.2 billion (which includes $1.8 billion for the Indonesia smelter projects that are being funded with proceeds from PT-FI's senior notes and its available credit facility).

We have cash on hand and the financial flexibility to fund capital expenditures and our other cash requirements for the year, including noncontrolling interest distributions, income tax payments, debt repayments, current common stock dividends (base and variable) and any share repurchases. At December 31, 2022, we had $8.1 billion of consolidated cash and cash equivalents (which includes $1.8 billion of cash for Indonesia smelter projects). In October 2022, we entered into a $3.0 billion, five-year, fully available unsecured revolving credit facility that replaced our prior revolving credit facility and PT-FI and Cerro Verde have $1.3 billion and $350 million, respectively, of availability under their revolving credit facilities. Refer to "Outlook" for further discussion of projected operating cash flows and capital expenditures for 2023 and to "Debt" below and Note 8 for further discussion.

<u>Financial Policy</u>. Our financial policy is aligned with our strategic objectives of maintaining a solid balance sheet and increasing cash returns to shareholders while advancing opportunities for future growth. The policy includes a base dividend and a performance-based payout framework, whereby up to 50% of available cash flows generated after planned capital spending and distributions to noncontrolling interest would be allocated to shareholder returns and the balance to debt reduction and investments in value enhancing growth projects, subject to us maintaining our net debt at a level not to exceed the net debt target of $3.0 billion to $4.0 billion (excluding project net debt for additional smelting capacity in Indonesia). The Board will review the structure of the performance-based payout framework at least annually.

At December 31, 2022, our net debt, excluding net debt for the Indonesia smelter projects, totaled $1.3 billion. Refer to "Net Debt" for further discussion.

In December 2022, our Board declared cash dividends totaling $0.15 per share on our common stock (including a $0.075 per share quarterly base cash dividend and a $0.075 per share quarterly variable, performance-based cash dividend), which was paid on February 1, 2023, to shareholders of record as of January 13, 2023. Based on current market conditions, the base and variable dividends on our common stock are anticipated to total $0.60 per share for 2023 (including the dividends paid on February 1, 2023), comprised of a $0.30 per share base dividend and $0.30 per share variable dividend. The declaration and payment of dividends (base or variable) is at the discretion of our

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

Board and will depend on our financial results, cash requirements, global economic conditions and other factors deemed relevant by our Board.

Refer to Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, and "Cautionary Statement" below for further discussion.

**Cash**

Following is a summary of the U.S. and international components of consolidated cash and cash equivalents available to the parent company, net of noncontrolling interests' share, taxes and other costs at December 31, 2022 (in billions):

---

| | | |
|:---|:---|:---|
| Cash at domestic companies | $4.9 |  |
| Cash at international operations | 3.2 |  |
| &nbsp;&nbsp;&nbsp;Total consolidated cash and cash equivalents | 8.1 |  |
| Cash for Indonesia smelter projects | (1.8) | <sup>a</sup> |
| Noncontrolling interests' share | (0.4) |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cash, net of noncontrolling interests' share | 5.9 |  |
| Withholding taxes | (0.1) |  |
| &nbsp;&nbsp;&nbsp;Net cash available | $5.8 |  |

---

a.Estimated remaining net proceeds from PT-FI's April 2022 senior notes offering.

Cash held at our international operations is generally used to support our foreign operations' capital expenditures, operating expenses, debt repayments, working capital or other cash needs. Management believes that sufficient liquidity is available in the U.S. from cash balances and availability from our revolving credit facility. We have not elected to permanently reinvest earnings from our foreign subsidiaries, and we have recorded deferred tax liabilities for foreign earnings that are available to be repatriated to the U.S. From time to time, our foreign subsidiaries distribute earnings to the U.S. through dividends that are subject to applicable withholding taxes and noncontrolling interests' share. See Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, for further discussion of our holding company structure and the potential impact of changes in tax laws.

**Debt**

At December 31, 2022, consolidated debt totaled $10.6 billion (including $1.0 billion of 3.875% Senior Notes maturing in March 2023, which we expect to pay using cash on hand), with a related weighted-average interest rate of 5.0%. Substantially all of our outstanding debt is fixed rate. We had no borrowings and $8 million in letters of credit issued under our $3.0 billion revolving credit facility. Additionally, no amounts were drawn under PT-FI's $1.3 billion revolving credit facility or Cerro Verde's $350 million revolving credit facility.

Refer to Note 8 for further discussion of the above items and for information regarding our debt arrangements.

**Operating Activities**

We generated consolidated operating cash flows of $5.1 billion in 2022 (net of $1.5 billion from working capital and other uses) and $7.7 billion in 2021 (including $0.8 billion from working capital and other sources).

Lower operating cash flows for 2022, compared with 2021, primarily reflect the timing of tax payments at our international operations and lower copper prices, partly offset by higher copper and gold sales volumes, and other working capital changes.

**Investing Activities**

<u>Capital Expenditures</u>. Capital expenditures, including capitalized interest, totaled $3.5 billion for the year 2022, including $1.7 billion for major mining projects primarily associated with the underground development activities in the Grasberg minerals district and $0.8 billion for the Indonesia smelter projects.

Capital expenditures, including capitalized interest, totaled $2.1 billion for the year 2021, including $1.25 billion for major projects primarily associated with underground development activities in the Grasberg minerals district.

A large portion of the capital expenditures relate to projects that are expected to add significant production and cash flow in future periods, enabling us to continue to generate operating cash flows exceeding capital expenditures in future years. Refer to "Outlook" for further discussion of projected capital expenditures for 2023.

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

<u>Proceed from Sales of Assets</u>. In September 2021, we completed the sale of our remaining Freeport Cobalt assets to Jervois Global Limited (Jervois) for $208 million, including net cash proceeds of $150 million and shares of Jervois. In May 2022, we sold all our shares in Jervois for proceeds of $60 million. Refer to Note 2 for further discussion.

<u>Loans to PT Smelting for Expansion</u>. PT-FI made loans to PT Smelting totaling $65 million in 2022 and $36 million in 2021 to fund PT Smelting's expansion project. Refer to Note 3 and "Operations - Indonesia Mining" for further discussion.

<u>Acquisition of Minority Interest in PT Smelting</u>. On April 30, 2021, PT-FI acquired 14.5% of the outstanding common stock of PT Smelting for $33 million, increasing its ownership interest from 25.0% to 39.5%. Refer to Note 2 for further discussion.

**Financing Activities**

<u>Debt Transactions</u>. Net borrowings of debt totaled $1.2 billion in 2022 and net repayments of debt totaled $0.3 billion in 2021. Net borrowings for 2022 included PT-FI's $3.0 billion senior notes offering that was completed in April 2022, partly offset by the purchases of our senior notes in open market transactions ($1.0 billion), and the repayment of borrowings under PT-FI's term loan ($0.6 billion) and Cerro Verde's term loan ($0.3 billion).

Net repayments of debt totaled $0.3 billion in 2021, primarily reflecting the redemption of $0.5 billion of senior notes and repayments of $0.2 billion under Cerro Verde's term loan, partly offset by borrowings under the PT-FI term loan ($0.4 billion).

Refer to Note 8 for further discussion.

<u>Cash Dividends on Common Stock</u>. We paid cash dividends on our common stock totaling $0.9 billion in 2022 and $0.3 billion in 2021. The increase in cash dividends in 2022 relates to the quarterly variable, performance-based cash dividend paid on our common stock. The declaration and payment of dividends (base or variable) is at the discretion of our Board and will depend on our financial results, cash requirements, global economic conditions and other factors deemed relevant by our Board. Refer to Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, "Cautionary Statement" below.

<u>Cash Dividends and Distributions Paid to Noncontrolling Interests</u>. Cash dividends and distributions paid to noncontrolling interests at our international operations totaled $0.8 billion in 2022 and $0.6 billion in 2021. Based on the current sales volume, cost estimates and assumed average prices in 2023 discussed in "Outlook," and the change in FCX's economic interest in PT-FI (refer to Note 3), we currently expect cash dividends and distributions paid to noncontrolling interests to exceed $1.8 billion in 2023. Cash dividends and distributions to noncontrolling interests vary based on the operating results and cash requirements of our consolidated subsidiaries.

<u>Treasury Stock Purchases</u>. In July 2022, the Board authorized an increase in the share repurchase program up to $5.0 billion. We have acquired 47.86 million shares of our common stock for a total cost of $1.8 billion ($38.35 average cost per share), including 35.12 million shares for a total cost of $1.3 billion ($38.36 cost per share) during 2022 and 12.74 million shares for a total cost of $0.5 billion ($38.32 cost per share) in 2021.

As of February 15, 2023, $3.2 billion remains available under the share repurchase program. The timing and amount of share repurchases is at the discretion of management and will depend on a variety of factors. The share repurchase program may be modified, increased, suspended or terminated at any time at the Board's discretion. Refer to Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, "Cautionary Statement" below and discussion of our financial policy above.

<u>Contributions from Noncontrolling Interests</u>. We received equity contributions totaling $0.2 billion in both 2022 and 2021 from PT Indonesia Asahan Aluminum (Persero) (PT Inalum, also known as MIND ID) for its share of capital spending on the underground mine development projects in the Grasberg minerals district. Beginning on January 1, 2023, capital spending at PT-FI is being shared in accordance with the shareholders' ownership interests.

<u>Stock-based awards</u>. Proceeds from exercised stock options totaled $125 million in 2022 and $210 million in 2021, and payments for related employee taxes totaled $55 million in 2022 and $29 million in 2021. See Note 10 for a discussion of stock-based awards.

**CONTINGENCIES**

Refer to Note 12 and "Critical Accounting Estimates," and Items 1. and 2. "Business and Properties" and Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, for further information about contingencies associated with environmental matters and AROs.

**Environmental**

The cost of complying with environmental laws is a fundamental and substantial cost of our business. At December 31, 2022, we had $1.7 billion recorded in our consolidated balance sheet for environmental obligations attributed to CERCLA or analogous state programs and for estimated future costs associated with environmental obligations that are considered probable based on specific facts and circumstances.

We incurred environmental capital expenditures and other environmental costs (including our joint venture partners' shares) to comply with applicable environmental laws and regulations that affect our operations totaling $0.4 billion in 2022 and $0.3 billion in 2021. For 2023, we expect to incur approximately $0.6 billion of aggregate environmental capital expenditures and other environmental costs. The timing and amount of estimated payments could change as a result of changes in regulatory requirements, changes in scope and timing of remediation, the settlement of environmental matters and the rate at which actual spending occurs on continuing matters.

**Asset Retirement Obligations**

We recognize AROs as liabilities when incurred, with the initial measurement at fair value. These obligations, which are initially estimated based on discounted cash flow estimates, are accreted to full value over time through charges to cost of sales. Mine reclamation costs for disturbances are recorded as an ARO and as a related asset retirement cost (included in property, plant, equipment and mine development costs) in the period of disturbance. For non-operating properties without mineral reserves, changes to the ARO are recorded in earnings. Our cost estimates are reflected on a third-party cost basis and comply with our legal obligation to retire tangible, long-lived assets. At December 31, 2022, we had $3.0 billion recorded in our consolidated balance sheet for AROs, including $0.3 billion related to our oil and gas properties. Spending on AROs totaled $0.2 billion in 2022 and 2021 (including $0.1 billion in 2022 and 2021 for our oil and gas operations). For 2023, we expect to incur approximately $0.2 billion in aggregate ARO expenditures (including $0.1 billion for our oil and gas operations).

PT-FI recorded ARO adjustments of $131 million in 2022 and $397 million in 2021, of which $116 million and $340 million, respectively, were charged to production and delivery costs as they relate to the depleted Grasberg open pit. Our Morenci and Bagdad mines recorded ARO adjustments in 2022 totaling $118 million and $65 million, respectively, associated with their updated closure strategies and plans for stockpiles and tailings impoundments that were submitted to the Arizona Department of Environmental Quality for approval.

**Litigation and Other Contingencies**

Refer to Note 12, and Item 1A. "Risk Factors" and Item 3. "Legal Proceedings" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, for further discussion of contingencies associated with legal proceedings and other matters.

**DISCLOSURES ABOUT MARKET RISKS**

**Commodity Price Risk**

Our 2022 consolidated revenues from our mining operations include the sale of copper concentrate, copper cathode, copper rod, gold, molybdenum and other metals by our North America and South America mines, the sale of copper concentrate (which also contains significant quantities of gold and silver) by our Indonesia mining operations, the sale of molybdenum in various forms by our molybdenum operations, and the sale of copper cathode, copper anode and gold in anode and slimes by Atlantic Copper. Our financial results will vary with fluctuations in the market prices of the commodities we produce, primarily copper and gold, and to a lesser extent molybdenum. For projected sensitivities of our operating cash flow to changes in commodity prices, refer to "Outlook." World market prices for these commodities have fluctuated historically and are affected by numerous factors beyond our control. Refer to Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022, for further discussion of financial risks associated with fluctuations in the market prices of the commodities we sell.

During 2022, our mined copper was sold 61% in concentrate, 18% as cathode and 21% as rod from North America operations. Substantially all of our copper concentrate and cathode sales contracts provide final copper pricing in a specified future month (generally one to four months from the shipment date) based primarily on quoted LME monthly average copper settlement prices. We receive market prices based on prices in the specified future period, which results in price fluctuations recorded through revenues until the date of settlement. We record revenues and invoice customers at the time of shipment based on then-current LME prices, which results in an embedded derivative on our provisionally priced concentrate and cathode sales that is adjusted to fair value through earnings each period, using the period-end forward prices, until final pricing on the date of settlement. To the extent final prices are higher or lower than what was recorded on a provisional basis, an increase or decrease to revenues is recorded each reporting period until the date of final pricing. Accordingly, in times of rising copper prices, our revenues benefit from adjustments to the final pricing of provisionally priced sales pursuant to contracts entered into in prior periods; in times of falling copper prices, the opposite occurs.

Following are the favorable impacts of net adjustments to the prior years' provisionally priced copper sales for the years ended December 31 (in millions, except per share amounts):

---

| | | |
|:---|:---|:---|
| | 2022 | 2021 |
| Revenues | $60 | $169 |
| Net income attributable to common stock | $25 | $65 |
| Net income per share attributable to common stock | $0.02 | $0.04 |

---

At December 31, 2022, we had provisionally priced copper sales at our copper mining operations totaling 535 million pounds of copper (net of intercompany sales and noncontrolling interests) recorded at an average price of $3.80 per pound, subject to final pricing over the next several months. We estimate that each $0.05 change in the price realized from the December 31, 2022, provisional price recorded would have an approximate $40 million effect on 2023 revenues ($13 million to net income attributable to common stock). The LME copper settlement price closed at $4.12 per pound on January 31, 2023.

**Foreign Currency Exchange Risk**

The functional currency for most of our operations is the U.S. dollar. Substantially all of our revenues and a significant portion of our costs are denominated in U.S. dollars; however, some costs and certain asset and liability accounts are denominated in local currencies, including the Indonesia rupiah, Peruvian sol, Chilean peso and euro. We recognized foreign currency translation gains on balances denominated in foreign currencies totaling $9 million in 2022 and $66 million in 2021. Generally, our operating results are positively affected when the U.S. dollar strengthens in relation to those foreign currencies and are adversely affected when the U.S. dollar weakens in relation to those foreign currencies.

Following is a summary of estimated annual payments and the impact of changes in foreign currency rates on our annual operating costs:

**NEW ACCOUNTING STANDARDS**

We did not adopt any new accounting standards in 2022 that had a material impact on our consolidated financial statements.

**NET DEBT**

Net debt, which we define as consolidated debt less consolidated cash and cash equivalents, is intended to provide investors with information related to the performance-based payout framework in our financial policy, which requires achievement of a net debt target in the range of $3 billion to $4 billion (excluding project debt for additional smelting capacity in Indonesia). This information differs from consolidated debt determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for consolidated debt determined in accordance with U.S. GAAP. Our net debt, which may not be comparable to similarly titled measures reported by other companies, follows (in billions):

---

|:---|:---|:---|
| | As of December 31, 2022 | As of December 31, 2021 |
| Current portion of debt | $1.0 | $0.4 |

**PRODUCT REVENUES AND PRODUCTION COSTS**

**Mining Product Revenues and Unit Net Cash Costs** 

Unit net cash costs per pound of copper and molybdenum are measures intended to provide investors with information about the cash-generating capacity of our mining operations expressed on a basis relating to the primary metal product for the respective operations. We use this measure for the same purpose and for monitoring operating performance by our mining operations. This information differs from measures of performance determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for measures of performance determined in accordance with U.S. GAAP. These measures are presented by other metals mining companies, although our measures may not be comparable to similarly titled measures reported by other companies.

We present gross profit per pound of copper in the following tables using both a "by-product" method and a "co-product" method. We use the by-product method in our presentation of gross profit per pound of copper because (i) the majority of our revenues are copper revenues, (ii) we mine ore, which contains copper, gold, molybdenum and other metals, (iii) it is not possible to specifically assign all of our costs to revenues from the copper, gold, molybdenum and other metals we produce, (iv) it is the method used to compare mining operations in certain industry publications and (v) it is the method used by our management and the Board to monitor operations and to compare mining operations in certain industry publications. In the co-product method presentations, shared costs are allocated to the different products based on their relative revenue values, which will vary to the extent our metals sales volumes and realized prices change.

We show revenue adjustments for prior period open sales as separate line items. Because these adjustments do not result from current period sales, these amounts have been reflected separately from revenues on current period sales. Noncash and other costs, which are removed from site production and delivery costs in the calculation of unit net cash costs, consist of items such as stock-based compensation costs, long-lived asset impairments, idle facility costs, feasibility and optimization study costs, restructuring and/or unusual charges. As discussed above, gold, molybdenum and other metal revenues at copper mines are reflected as credits against site production and delivery costs in the by-product method. The following schedules are presentations under both the by-product and co-product methods together with reconciliations to amounts reported in our consolidated financial statements.

The words "anticipates," "may," "can," "plans," "believes," "estimates," "expects," "projects," "targets," "intends," "likely," "will," "should," "could," "to be," "potential," "assumptions," "guidance," "aspirations," "future," "commitments," "pursues," "initiatives," "objectives," "opportunities," "strategy" and any similar expressions are intended to identify those assertions as forward-looking statements. The declaration and payment of dividends (base or variable), and timing and amount of any share repurchases is at the discretion of our Board and management, respectively, and is subject to a number of factors, including maintaining our net debt target, capital availability, our financial results, cash requirements, global economic conditions, changes in laws, contractual restrictions and other factors deemed relevant by our Board or management, as applicable. Our share repurchase program may be modified, increased, suspended or terminated at any time at the Board's discretion.

We caution readers that forward-looking statements are not guarantees of future performance and actual results may differ materially from those anticipated, expected, projected or assumed in the forward-looking statements. Important factors that can cause our actual results to differ materially from those anticipated in the forward-looking statements include, but are not limited to, supply of and demand for, and prices of the commodities we produce, primarily copper; price and availability of consumables and components we purchase as well as constraints on supply and logistics, and transportation services; changes in our cash requirements, financial position, financing or investment plans; changes in general market, economic, regulatory or industry conditions, including as a result of Russia's invasion of Ukraine or potential global economic downturn or recession; reductions in liquidity and access to capital; changes in tax laws and regulations, including the impact of the Act; any major public health crisis; political and social risks, including the potential effects of violence in Indonesia, civil unrest in Peru, and relations with local communities and Indigenous Peoples; operational risks inherent in mining, with higher inherent risks in underground mining; mine sequencing; changes in mine plans or operational modifications, delays, deferrals or cancellations; production rates; timing of shipments; results of technical, economic or feasibility studies; potential inventory adjustments; potential impairment of long-lived mining assets; the Indonesia government's extension of PT-FI's copper concentrate export license after March 19, 2023; PT-FI's ability to export and sell copper concentrate and anode slimes; satisfaction of requirements in accordance with PT-FI's IUPK to extend mining rights from 2031 through 2041; the Indonesia government's approval of a deferred schedule for completion of additional domestic smelting capacity in Indonesia; discussions relating to the extension of PT-FI's IUPK beyond 2041; cybersecurity incidents; labor relations, including labor-related work stoppages and costs; the results of the PT-FI human health assessment to evaluate the potential impacts of tailings and mining waste, and compliance with applicable environmental, health and safety laws and regulations; weather- and climate-related risks; environmental risks, including availability of secure water supplies, and litigation results; our ability to comply with our responsible production commitments under specific frameworks and any changes to such frameworks and other factors described in more detail in Item 1A. "Risk Factors" contained in Part I of our annual report on Form 10-K for the year ended December 31, 2022.

Investors are cautioned that many of the assumptions upon which our forward-looking statements are based are likely to change after the date the forward-looking statements are made, including for example commodity prices, which we cannot control, and production volumes and costs or technological solutions and innovation, some aspects of which we may not be able to control. Further, we may make changes to our business plans that could affect our results. We caution investors that we undertake no obligation to update any forward-looking statements, which speak only as of the date made, notwithstanding any changes in our assumptions, changes in business plans, actual experience or other changes.

Estimates of mineral reserves and mineral resources are subject to considerable uncertainty. Such estimates are, to a large extent, based on metal prices for the commodities we produce and interpretations of geologic data, which may not necessarily be indicative of future results or quantities ultimately recovered. Our annual report on Form 10-K for the year ended December 31, 2022, also includes forward-looking statements regarding mineral resources not included in proven and probable mineral reserves. A mineral resource, which includes measured, indicated and inferred mineral resources, is a concentration or occurrence of material of economic interest in or on the Earth's crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. Such a deposit cannot qualify as recoverable proven and probable mineral reserves until legal and economic feasibility are confirmed based upon a comprehensive evaluation of development and operating costs, grades, recoveries and other material modifying factors. Accordingly, no assurance can be given that the estimated mineral resources will become proven and probable mineral reserves.

 **Item 8. Financial Statements and Supplementary Data.**

**MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING**

Freeport-McMoRan Inc.'s (the Company's) management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of, the Company's principal executive and principal financial officers and effected by the Company's Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the Company's assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management, including our principal executive officer and principal financial officer, assessed the effectiveness of our internal control over financial reporting as of the end of the fiscal year covered by this annual report on Form 10-K. In making this assessment, our management used the criteria set forth in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). Based on its assessment, management concluded that, as of December 31, 2022, our Company's internal control over financial reporting is effective based on the COSO criteria.

Ernst & Young LLP, an independent registered public accounting firm, who audited the Company's consolidated financial statements included in this Form 10-K, has issued an attestation report on the Company's internal control over financial reporting, which is included herein.

We have audited Freeport-McMoRan Inc.'s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Freeport-McMoRan Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on the COSO criteria.

&nbsp;&nbsp;&nbsp;&nbsp;

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of Freeport-McMoRan Inc. as of December 31, 2022 and 2021, the related consolidated statements of income, comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2022, and the related notes and our report dated February 15, 2023 expressed an unqualified opinion thereon.

**Basis for Opinion**

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

**Definition and Limitations of Internal Control Over Financial Reporting**

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the Board of Directors and Stockholders of

Freeport-McMoRan Inc.

**Opinion on the Financial Statements**

We have audited the accompanying consolidated balance sheets of Freeport-McMoRan Inc. (the Company) as of December 31, 2022 and 2021, the related consolidated statements of income, comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2022, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 15, 2023 expressed an unqualified opinion thereon.

**Basis for Opinion**

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matters**

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

| | |
|:---|:---|
| | ***Uncertain tax positions*** |
| *Description of the Matter* | As discussed in Note 12 to the consolidated financial statements, the Company operates in the United States and multiple international tax jurisdictions, and its income tax returns are subject to examination by tax authorities in those jurisdictions who may challenge any tax position on these returns. Uncertainty in a tax position may arise because tax laws are subject to interpretation. The Company uses significant judgment to (1) determine whether, based on the technical merits, a tax position is more likely than not to be sustained and (2) measure the amount of tax benefit that qualifies for recognition.  |

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

Auditing management's estimate of the amount of tax benefit that qualifies for recognition involved auditor judgment because management's estimate is complex, requires a high degree of judgment and is based on interpretations of tax laws and legal rulings.<br>

---

| | |
|:---|:---|
| *How We Addressed the Matter in Our Audit* | We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company's accounting process for uncertain tax positions. This included testing controls over management's review of the technical merits of tax positions and disputed tax assessments, including the process to measure the financial statement impact of these tax matters.  |
|  | Our audit procedures included, among others, evaluating the Company's accounting for these tax positions by using our knowledge of and experience with the application of respective tax laws by the relevant tax authorities, or our understanding of the contractual arrangements with the applicable government, if the position is governed by a contract. We analyzed the Company's assumptions and data used to determine the tax assessments and tested the accuracy of the calculations. We involved our tax professionals located in the respective jurisdictions to assess the technical merits of the Company's tax positions and to evaluate the application of relevant tax laws in the Company's recognition determination. We assessed the Company's correspondence with the relevant tax authorities and evaluated third-party tax or legal opinions obtained by the Company. We also evaluated the adequacy of the Company's disclosures included in Notes 11 and 12 in relation to these tax matters. |
|  | ***Environmental obligations*** |
| *Description of the Matter* | As discussed in Note 12 to the consolidated financial statements, the Company is subject to national, state and local environmental laws and regulations governing the protection of the environment, including restoration and reclamation of environmental contamination. Liabilities for environmental contingencies are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. At December 31, 2022, the Company's consolidated environmental obligations totaled $1.7 billion. |
|  | Auditing management's accounting for environmental obligations was challenging because significant judgment was required by the Company to estimate the future costs to remediate the environmental matters. The significant judgment was primarily due to the inherent estimation uncertainty relating to the amount of future costs. Such uncertainties involve assumptions regarding the nature and extent of contamination at each site, the nature and extent of required cleanup efforts under existing environmental regulations, the duration and effectiveness of the chosen remedial strategy, and allocation of costs among other potentially responsible parties. Actual costs incurred in future periods could differ from amounts estimated.  |

| | |
|:---|:---|
| *How We Addressed the Matter in Our Audit* | We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company's measurement of the environmental loss contingencies. For example, we tested controls over management's review of the environmental loss contingency calculations and management's assessment to evaluate key judgments and estimates affecting the environmental loss contingencies.  |
| | To test the Company's measurement of the environmental loss contingencies, among other procedures, we inspected correspondence with regulatory agencies, obtained external legal counsel confirmation letters, and inspected environmental studies. Additionally, we assessed the appropriateness of the Company's models and tested the significant assumptions discussed above along with the underlying data used by the Company in its analyses. We utilized our environmental professionals to search for new or contrary evidence related to the Company's sites and to assist in evaluating the reasonableness of estimated future costs by comparing the estimated future costs to environmental permits, third party observable data such as vendor quotes, and to historical costs incurred for similar activities. |

**Freeport-McMoRan Inc.**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

**Basis of Presentation.** The consolidated financial statements of Freeport-McMoRan Inc. (FCX) include the accounts of those subsidiaries where it directly or indirectly has more than 50% of the voting rights and/or has control over the subsidiary. As of December 31, 2022, the most significant entities that FCX consolidates include its 48.76%-owned subsidiary PT Freeport Indonesia (PT-FI), and the following wholly owned subsidiaries: Freeport Minerals Corporation (FMC) and Atlantic Copper, S.L.U. (Atlantic Copper). Refer to Note 3 for further discussion, including FCX's conclusion to consolidate PT-FI.

FMC's unincorporated joint venture at Morenci is reflected using the proportionate consolidation method (refer to Note 3 for further discussion). Investments in unconsolidated companies over which FCX has the ability to exercise significant influence, but does not control, are accounted for under the equity method and include PT-FI's investment in PT Smelting (refer to Note 3 for further discussion). Investments in unconsolidated companies owned less than 20%, and for which FCX does not exercise significant influence, are recorded at (i) fair value for those that have a readily determinable fair value or (ii) cost, less any impairment, for those that do not have a readily determinable fair value. All significant intercompany transactions have been eliminated. Dollar amounts in tables are stated in millions, except per share amounts.

**Business Segments.** FCX has organized its mining operations into four primary divisions - North America copper mines, South America mining, Indonesia mining and Molybdenum mines, and operating segments that meet certain thresholds are reportable segments. FCX's reportable segments include the Morenci, Cerro Verde and Grasberg (Indonesia mining) copper mines, the Rod & Refining operations and Atlantic Copper Smelting & Refining. Refer to Note 16 for further discussion.

**Use of Estimates.** The preparation of FCX's financial statements in conformity with accounting principles generally accepted in the United States (U.S.) requires management to make estimates and assumptions that affect the amounts reported in these financial statements and accompanying notes. The more significant areas requiring the use of management estimates include minerals reserve estimation; asset lives for depreciation, depletion and amortization; environmental obligations; asset retirement obligations; estimates of recoverable copper in mill and leach stockpiles; deferred taxes and valuation allowances; reserves for contingencies and litigation; asset acquisitions and impairment, including estimates used to derive future cash flows associated with those assets; pension benefits; and valuation of derivative instruments. Actual results could differ from those estimates.

**Functional Currency.** The functional currency for the majority of FCX's foreign operations is the U.S. dollar. For foreign subsidiaries whose functional currency is the U.S. dollar, monetary assets and liabilities denominated in the local currency are translated at current exchange rates, and non-monetary assets and liabilities, such as inventories, property, plant, equipment and mine development costs, are translated at historical exchange rates. Gains and losses resulting from translation of such account balances are included in other income (expense), net, as are gains and losses from foreign currency transactions. Foreign currency gains totaled $9 million in 2022, $66 million in 2021 and $34 million in 2020.

**Cash Equivalents.** Highly liquid investments purchased with maturities of three months or less are considered cash equivalents.

**Restricted Cash and Cash Equivalents.** FCX's restricted cash and cash equivalents are primarily related to PT-FI's commitment for the development of a greenfield smelter in Indonesia; and guarantees and commitments for certain mine closure and reclamation obligations. Restricted cash and cash equivalents are classified as a current or long-term asset based on the timing and nature of when or how the cash is expected to be used or when the restrictions are expected to lapse. Restricted cash and cash equivalents are comprised of bank deposits and money market funds.

**Inventories.** Inventories include materials and supplies, mill and leach stockpiles, and product inventories. Inventories are stated at the lower of weighted-average cost or net realizable value (NRV).

*Mill and Leach Stockpiles.* Mill and leach stockpiles are work-in-process inventories for FCX's mining operations. Mill and leach stockpiles contain ore that has been extracted from an ore body and is available for metal recovery. Mill stockpiles contain sulfide ores, and recovery of metal is through milling, concentrating and smelting and refining or, alternatively, by concentrate leaching. Leach stockpiles contain oxide ores and certain secondary sulfide ores and recovery of metal is through exposure to acidic solutions that dissolve contained copper and deliver it in solution to extraction processing facilities (*i.e.,* solution extraction and electrowinning (SX/EW)). The recorded cost of mill and leach stockpiles includes mining and haulage costs incurred to deliver ore to stockpiles, depreciation, depletion, amortization and site overhead costs. Material is removed from the stockpiles at a weighted-average cost per pound. Each mine site maintains one work-in-progress balance on a weighted-average cost basis for each process (*i.e.*, leach, mill or concentrate leach) regardless of the number of stockpile systems at that site.

Because it is impracticable to determine copper contained in mill and leach stockpiles by physical count, reasonable estimation methods are employed. The quantity of material delivered to mill and leach stockpiles is based on surveyed volumes of mined material and daily production records. Sampling and assaying of blasthole cuttings determine the estimated copper grade of the material delivered to mill and leach stockpiles.

Expected copper recoveries for mill stockpiles are determined by metallurgical testing. The recoverable copper in mill stockpiles, once entered into the production process, can be produced into copper concentrate almost immediately.

Expected copper recoveries for leach stockpiles are determined using small-scale laboratory tests, small- to large-scale column testing (which simulates the production process), historical trends and other factors, including mineralogy of the ore and rock type. Total copper recovery in leach stockpiles can vary significantly from a low percentage to more than 90% depending on several variables, including processing methodology, processing variables, mineralogy and particle size of the rock. For newly placed material on active stockpiles, as much as 80% of the total copper recovery may occur during the first year, and the remaining copper may be recovered over many years.

Process rates and copper recoveries for mill and leach stockpiles are monitored regularly, and recovery estimates are adjusted periodically as additional information becomes available and as related technology changes. Recovery adjustments will typically result in a future impact to the value of the material removed from the stockpiles at a revised weighted-average cost per pound of recoverable copper.

*Product.* Product inventories include raw materials, work-in-process and finished goods. Corporate general and administrative costs are not included in inventory costs.

Raw materials are primarily unprocessed concentrate at Atlantic Copper's smelting and refining operations.

Work-in-process inventories are primarily copper concentrate at various stages of conversion into anode and cathode at Atlantic Copper's operations. Atlantic Copper's in-process inventories are valued at the weighted-average cost of the material fed to the smelting and refining process plus in-process conversion costs.

Finished goods for mining operations represent salable products (*e.g.*, copper and molybdenum concentrate, copper anode, copper cathode, copper rod, molybdenum oxide, and high-purity molybdenum chemicals and other metallurgical products). Finished goods are valued based on the weighted-average cost of source material plus applicable conversion costs relating to associated process facilities. Costs of finished goods and work-in-process (*i.e.*, not raw materials) inventories include labor and benefits, supplies, energy, depreciation, depletion, amortization, site overhead costs and other necessary costs associated with the extraction and processing of ore, such as mining, milling, smelting, leaching, SX/EW, refining, roasting and chemical processing.

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

**Property, Plant, Equipment and Mine Development Costs.** Property, plant, equipment and mine development costs are carried at cost. Mineral exploration costs, as well as drilling and other costs incurred for the purpose of converting mineral resources to proven and probable mineral reserves or identifying new mineral resources at development or production stage properties, are charged to expense as incurred. Development costs are capitalized beginning after proven and probable mineral reserves have been established. Development costs include costs incurred resulting from mine pre-production activities undertaken to gain access to proven and probable mineral reserves, including shafts, adits, drifts, ramps, permanent excavations, infrastructure and removal of overburden. For underground mines certain costs related to panel development, such as undercutting and drawpoint development, are also capitalized as mine development costs until production reaches sustained design capacity for the mine. After reaching design capacity, the mine transitions to the production phase and panel development costs are allocated to inventory and then included as a component of cost of goods sold. Additionally, interest expense allocable to the cost of developing mining properties and to constructing new facilities is capitalized until assets are ready for their intended use.

Expenditures for replacements and improvements are capitalized. Costs related to periodic scheduled maintenance (*i.e.*, turnarounds) are charged to expense as incurred. Depreciation for mining and milling life-of-mine assets, infrastructure and other common costs is determined using the unit-of-production (UOP) method based on total estimated recoverable proven and probable copper reserves (for primary copper mines) and proven and probable molybdenum reserves (for primary molybdenum mines). Development costs and acquisition costs for proven and probable mineral reserves that relate to a specific ore body are depreciated using the UOP method based on estimated recoverable proven and probable mineral reserves for the ore body benefited. Depreciation, depletion and amortization using the UOP method is recorded upon extraction of the recoverable copper or molybdenum from the ore body or production of finished goods (as applicable), at which time it is allocated to inventory cost and then included as a component of cost of goods sold. Other assets are depreciated on a straight-line basis over estimated useful lives for the related assets of up to 50 years for buildings and 3 to 50 years for machinery and equipment, and mobile equipment.

Included in property, plant, equipment and mine development costs is value beyond proven and probable mineral reserves (VBPP), primarily resulting from FCX's acquisition of FMC. The concept of VBPP may be interpreted differently by different mining companies. FCX's VBPP is attributable to (i) measured and indicated mineral resources, that FCX believes could be brought into production with the establishment or modification of required permits and should market conditions and technical assessments warrant, (ii) inferred mineral resources and (iii) exploration potential.

Carrying amounts assigned to VBPP are not charged to expense until the VBPP becomes associated with additional proven and probable mineral reserves and the reserves are produced or the VBPP is determined to be impaired. Additions to proven and probable mineral reserves for properties with VBPP will carry with them the value assigned to VBPP at the date acquired, less any impairment amounts. Refer to Note 5 for further discussion.

**Impairment of Long-Lived Mining Assets.** FCX assesses the carrying values of its long-lived mining assets for impairment when events or changes in circumstances indicate that the related carrying amounts of such assets may not be recoverable. In evaluating long-lived mining assets for recoverability, estimates of pre-tax undiscounted future cash flows of FCX's individual mines are used. An impairment is considered to exist if total estimated undiscounted future cash flows are less than the carrying amount of the asset. Once it is determined that an impairment exists, an impairment loss is measured as the amount by which the asset carrying value exceeds its fair value. The estimated undiscounted cash flows used to assess recoverability of long-lived assets and to measure the fair value of FCX's mining operations are derived from current business plans, which are developed using near-term price forecasts reflective of the current price environment and management's projections for long-term average metal prices. In addition to near- and long-term metal price assumptions, other key assumptions include estimates of commodity-based and other input costs; proven and probable mineral reserves estimates, including the timing and cost to develop and produce the reserves; VBPP estimates; and the use of appropriate discount rates in the measurement of fair value. FCX believes its estimates and models used to determine fair value are similar to what a market participant would use. As quoted market prices are unavailable for FCX's individual mining operations, fair value is determined through the use of after-tax discounted estimated future cash flows (*i.e.*, Level 3 measurement).

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

**Deferred Mining Costs.** Stripping costs (*i.e.*, the costs of removing overburden and waste material to access mineral deposits) incurred during the production phase of an open-pit mine are considered variable production costs and are included as a component of inventory produced during the period in which stripping costs are incurred. Major development expenditures, including stripping costs to prepare unique and identifiable areas outside the current mining area for future production that are considered to be pre-production mine development, are capitalized and amortized using the UOP method based on estimated recoverable proven and probable mineral reserves for the ore body benefited. However, where a second or subsequent pit or major expansion is considered to be a continuation of existing mining activities, stripping costs are accounted for as a current production cost and a component of the associated inventory.

**Environmental Obligations.** Environmental expenditures are charged to expense or capitalized, depending upon their future economic benefits. Accruals for such expenditures are recorded when it is probable that obligations have been incurred and the costs can be reasonably estimated. Environmental obligations attributed to the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) or analogous state programs are considered probable when a claim is asserted, or is probable of assertion, and FCX, or any of its subsidiaries, have been associated with the site. Other environmental remediation obligations are considered probable based on specific facts and circumstances. FCX's estimates of these costs are based on an evaluation of various factors, including currently available facts, existing technology, presently enacted laws and regulations, remediation experience, whether or not FCX is a potentially responsible party (PRP) and the ability of other PRPs to pay their allocated portions. With the exception of those obligations assumed in the acquisition of FMC that were initially recorded at estimated fair values (refer to Note 12 for further discussion), environmental obligations are recorded on an undiscounted basis. Where the available information is sufficient to estimate the amount of the obligation, that estimate has been used. Where the information is only sufficient to establish a range of probable liability and no point within the range is more likely than any other, the lower end of the range has been used. Possible recoveries of some of these costs from other parties are not recognized in the consolidated financial statements until they become probable. Legal costs associated with environmental remediation (such as fees to third-party legal firms for work relating to determining the extent and type of remedial actions and the allocation of costs among PRPs) are included as part of the estimated obligation.

Environmental obligations assumed in the acquisition of FMC, which were initially recorded at fair value and estimated on a discounted basis, are accreted to full value over time through charges to interest expense. Adjustments arising from changes in amounts and timing of estimated costs and settlements may result in increases and decreases in these obligations and are calculated in the same manner as they were initially estimated. Unless these adjustments qualify for capitalization, changes in environmental obligations are charged to operating income when they occur.

FCX performs a comprehensive review of its environmental obligations annually and also reviews changes in facts and circumstances associated with these obligations at least quarterly.

**Asset Retirement Obligations.** FCX records the fair value of estimated asset retirement obligations (AROs) associated with tangible long-lived assets in the period incurred. AROs associated with long-lived assets are those for which there is a legal obligation to settle under existing or enacted law, statute, written or oral contract or by legal construction. These obligations, which are initially estimated based on discounted cash flow estimates, are accreted to full value over time through charges to cost of sales. In addition, asset retirement costs (ARCs) are capitalized as part of the related asset's carrying value and are depreciated over the asset's useful life.

For mining operations, reclamation costs for disturbances are recognized as an ARO and as a related ARC in the period of the disturbance and depreciated primarily on a UOP basis. FCX's AROs for mining operations consist primarily of costs associated with mine reclamation and closure activities. These activities, which are site specific, generally include costs for earthwork, revegetation, water treatment and demolition.

For non-operating properties without reserves, changes to the ARO are recorded in earnings.

At least annually, FCX reviews its ARO estimates for changes in the projected timing of certain reclamation and closure/restoration costs, changes in cost estimates and additional AROs incurred during the period. Refer to Note 12 for further discussion.

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

**Revenue Recognition.** FCX recognizes revenue for its products upon transfer of control in an amount that reflects the consideration it expects to receive in exchange for those products. Transfer of control is in accordance with the terms of customer contracts, which is generally upon shipment or delivery of the product. While payment terms vary by contract, terms generally include payment to be made within 30 days, but not longer than 60 days. Certain of FCX's concentrate and cathode sales contracts also provide for provisional pricing, which is accounted for as an embedded derivative (refer to Note 14 for further discussion). For provisionally priced sales, 90% to 100% of the provisional invoice amount is collected upon shipment or within 20 days, and final balances are settled in a contractually specified future month (generally one to four months from the shipment date) based on quoted monthly average copper settlement prices on the London Metal Exchange (LME) or the Commodity Exchange Inc. (COMEX), and quoted monthly average London Bullion Market Association (London) PM gold prices.

FCX's product revenues are also recorded net of treatment charges, royalties and export duties. Moreover, because a portion of the metals contained in copper concentrate is unrecoverable as a result of the smelting process, FCX's revenues from concentrate sales are also recorded net of allowances based on the quantity and value of these unrecoverable metals. These allowances are a negotiated term of FCX's contracts and vary by customer. Treatment and refining charges represent payments or price adjustments to smelters and refiners that are generally fixed. Refer to Note 16 for a summary of revenue by product type.

Gold sales are priced according to individual contract terms, generally the average London PM gold price for a specified month near the month of shipment.

The majority of FCX's molybdenum sales are priced based on the average published *Platts Metals Daily* price, plus conversion premiums for products that undergo additional processing, such as ferromolybdenum and molybdenum chemical products, for the month prior to the month of shipment.

**Stock-Based Compensation.** Compensation costs for share-based payments to employees are measured at fair value and charged to expense over the requisite service period for awards that are expected to vest. The fair value of stock options is determined using the Black-Scholes-Merton option valuation model. The fair value for stock-settled restricted stock units (RSUs) is based on FCX's stock price on the date of grant. Shares of common stock are issued at the vesting date for stock-settled RSUs. The fair value of performance share units (PSUs) are determined using FCX's stock price and a Monte-Carlo simulation model. The fair value for liability-classified awards (*i.e.*, cash-settled RSUs) is remeasured each reporting period using FCX's stock price. FCX has elected to recognize compensation costs for stock option awards that vest over several years on a straight-line basis over the vesting period, and for RSUs on the graded-vesting method over the vesting period. Refer to Note 10 for further discussion.

**Earnings Per Share.** FCX calculates its basic net income per share of common stock under the two-class method and calculates its diluted net income per share of common stock using the more dilutive of the two-class method or the treasury-stock method. Basic net income per share of common stock was computed by dividing net income attributable to common stockholders (after deducting undistributed dividends and earnings allocated to participating securities) by the weighted-average shares of common stock outstanding during the year. Diluted net income per share of common stock was calculated by including the basic weighted-average shares of common stock outstanding adjusted for the effects of all potential dilutive shares of common stock, unless their effect would be antidilutive.

Outstanding stock options with exercise prices greater than the average market price of FCX's common stock during the year are excluded from the computation of diluted net income per share of common stock. Excluded shares of common stock totaled 1 million shares in 2022, 5 million shares in 2021 and 31 million shares in 2020.

**Global Intangible Low-Taxed Income (GILTI).** FCX has elected to treat taxes due on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred.

**Subsequent Events.** Since February 11, 2023, PT-FI's operations have been temporarily disrupted because of significant rainfall and landslides, which restricted access to infrastructure near its milling operations. Recovery activities are in progress to clear debris from the affected areas and PT-FI is in the process of gradually resuming operations. Operations are expected to be fully restored by the end of February 2023.

FCX evaluated events after December 31, 2022, and through the date the financial statements were issued, and determined any events or transactions occurring during this period that would require recognition or disclosure are appropriately addressed in these financial statements.

**NOTE 2. ACQUISITIONS AND DISPOSITIONS** 

**Cobalt Business.** In September 2021, FCX's 56% owned subsidiary, Koboltti Chemicals Holdings Limited (KCHL), completed the sale of its remaining cobalt business based in Kokkola, Finland (Freeport Cobalt) to Jervois Global Limited (Jervois) for $208 million (before post-closing adjustments), consisting of cash consideration of $173 million and 7% of Jervois common stock (valued at $35 million at the time of closing). In 2022, KCHL sold these shares for $60 million. At closing, Freeport Cobalt's assets included cash of approximately $20 million and other net assets of $125 million. In 2021, FCX recorded a gain of $60 million ($34 million to net income attributable to common stock) associated with this transaction. In addition, KCHL has the right to receive contingent consideration through 2026 of up to $40 million based on the future performance of Freeport Cobalt. Any gain related to the contingent consideration will be recognized when received. Following this transaction, FCX no longer has cobalt operations.

**PT Smelting.** On April 30, 2021, PT-FI acquired 14.5% of the outstanding common stock of PT Smelting, a smelter and refinery in Gresik, Indonesia, for $33 million, increasing its ownership interest from 25.0% to 39.5%. The remaining outstanding shares of PT Smelting are owned by Mitsubishi Materials Corporation (MMC). PT-FI accounts for its investment in PT Smelting under the equity method (refer to Note 3 for further discussion).

**Kisanfu Transaction.** In December 2020, FCX completed the sale of its interests in the Kisanfu undeveloped copper and cobalt resource in the Democratic Republic of Congo to a wholly owned subsidiary of China Molybdenum Co., Ltd. (CMOC) for $550 million, with after-tax net cash proceeds totaling $415 million. FCX did not have any proven and probable mineral reserves associated with the Kisanfu project. FCX recorded a gain of $486 million in 2020 associated with this transaction.

**Timok Transactions.** In 2016, FCX sold an interest in the upper zone of the Timok exploration project in Serbia (the 2016 Transaction). In December 2019, FCX completed the sale of its interest in the lower zone of the Timok

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

exploration project to an affiliate of the purchaser in the 2016 Transaction, which included the right to future contingent payments of up to $150 million. These future contingent payments will be based on the future sale of products (as defined in the agreement) from the Timok lower zone. For a period of 12 months after the third anniversary of the initial sale of products from the Timok lower zone, the purchaser can settle, or FCX can demand payment of, such deferred payment obligation, in each case, for a total of $60 million. As these deferred payments are contingent upon future production (the Timok lower zone project is still pre-operational) and would result in gain recognition, no amounts were recorded upon the closing of the transaction. Subsequent recognition will be based on the gain contingency model, in which the consideration would be recorded in the period in which all contingencies are resolved and the gain is realized. This is expected to be when FCX (i) is provided periodic product sales information by the purchaser or (ii) gives notice to the purchaser or receives notice from the purchaser regarding the settlement of the deferred payments for $60 million.

In addition and in connection with the transaction in 2019, in lieu of payment upon achievement of defined development milestones provided for in the 2016 Transaction, the purchaser paid $107 million in three installments of $12 million in 2022, $50 million in 2021 and $45 million in 2020.

**TF Holdings Limited - Discontinued Operations.** In 2016, FCX completed the sale of its 70% interest in TF Holdings Limited to CMOC for $2.65 billion in cash (before closing adjustments) and contingent consideration of up to $120 million in cash. In 2020, FCX realized and collected contingent consideration of $60 million and no additional amount is realizable.

**NOTE 3. OWNERSHIP IN SUBSIDIARIES AND JOINT VENTURES**

**Ownership in Subsidiaries.** FMC produces copper and molybdenum from mines in North America and South America. At December 31, 2022, FMC's operating mines in North America were Morenci, Bagdad, Safford (including Lone Star), Sierrita and Miami located in Arizona; Tyrone and Chino located in New Mexico; and Henderson and Climax located in Colorado. FMC has a 72% interest in Morenci (refer to "Joint Venture. Sumitomo and SMM Morenci, Inc.") and owns 100% of the other North America mines. At December 31, 2022, operating mines in South America were Cerro Verde (53.56% owned) located in Peru and El Abra (51% owned) located in Chile. At December 31, 2022, FMC's net assets totaled $19.0 billion and its accumulated deficit totaled $12.2 billion. FCX had $1 million in loans to FMC outstanding at December 31, 2022.

FCX owns 48.76% of PT-FI (refer to "PT-FI Divestment"). At December 31, 2022, PT-FI's net assets totaled $13.0 billion and its retained earnings totaled $8.4 billion. FCX had no loans to PT-FI outstanding at December 31, 2022.

FCX owns 100% of the outstanding Atlantic Copper (FCX's wholly owned smelting and refining unit in Spain) common stock. At December 31, 2022, Atlantic Copper's net assets totaled $104 million and its accumulated deficit totaled $440 million. FCX had $456 million in loans to Atlantic Copper outstanding at December 31, 2022.

**PT-FI Divestment.** On December 21, 2018, FCX completed the transaction with the Indonesia government regarding PT-FI's long-term mining rights and share ownership (the 2018 Transaction). Pursuant to the divestment agreement and related documents, PT Indonesia Asahan Aluminium (Persero) (PT Inalum, also known as MIND ID), an Indonesia state-owned enterprise, acquired all of Rio Tinto plc's (Rio Tinto) interests associated with its joint venture with PT-FI (the former Rio Tinto Joint Venture) and 100% of FCX's interests in PT Indonesia Papua Metal Dan Mineral (PTI - formerly known as PT Indocopper Investama).

In connection with the 2018 Transaction, PT-FI acquired all of the common stock of PT Rio Tinto Indonesia that held the former Rio Tinto Joint Venture interest. After the 2018 Transaction, MIND ID's (26.24%) and PTI's (25.00%) collective share ownership of PT-FI totals 51.24% and FCX's share ownership totals 48.76%. The arrangements provide for FCX and the other pre-transaction PT-FI shareholders (*i.e.*, MIND ID) to retain the economics of the revenue and cost sharing arrangements under the former Rio Tinto Joint Venture. As a result, FCX's economic interest in PT-FI approximated 81% through 2022 and is 48.76% thereafter (see further discussion below).

FCX, PT-FI, PTI and MIND ID entered into a shareholders agreement (the PT-FI Shareholders Agreement), which includes provisions related to the governance and management of PT-FI. FCX considered the terms of the PT-FI Shareholders Agreement and related governance structure, including whether MIND ID has substantive participating rights, and concluded that it has retained control and would continue to consolidate PT-FI in its financial statements following the 2018 Transaction. Among other terms, the governance arrangements under the PT-FI Shareholders Agreement transfers control over the management of PT-FI's mining operations to an operating committee, which is controlled by FCX. Additionally, as discussed above, the existing PT-FI shareholders will retain

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

the economics of the revenue and cost sharing arrangements under the former Rio Tinto Joint Venture, so that FCX's economic interest in the project through 2041 will not be significantly affected by the 2018 Transaction. FCX believes its conclusion to continue to consolidate PT-FI in its financial statements is in accordance with the U.S. Securities and Exchange Commission (SEC) Regulation S-X, Rule 3A-02 (a), which provides for situations in which consolidation of an entity, notwithstanding the lack of majority ownership, is necessary to present fairly the financial position and results of operations of the registrant, because of the existence of a parent-subsidiary relationship by means other than record ownership of voting stock.

*Attribution of PT-FI Net Income or Loss.* FCX concluded that the attribution of PT-FI's net income or loss from December 21, 2018 (the date of the divestment transaction), through December 31, 2022 (the Initial Period), should be based on the economics replacement agreement included in the PT-FI Shareholders Agreement, as previously discussed. The economics replacement agreement entitled FCX to approximately 81% of PT-FI dividends paid during the Initial Period, with the remaining 19% paid to the noncontrolling interests. PT-FI's cumulative net income during the Initial Period totaled $6.0 billion, of which $4.9 billion was attributed to FCX. In addition, because PT-FI did not achieve the Gold Target (as defined in the PT-FI Shareholders Agreement) during the Initial Period, PT-FI's net income and cash dividends associated with the sale of approximately 190,000 ounces of gold in 2023 will be attributed approximately 81% to FCX and 19% to MIND ID.

Beginning January 1, 2023, the attribution of PT-FI's net income or loss will be based on equity ownership percentages (48.76% for FCX, 26.24% for MIND ID and 25.00% for PTI), except for the net income attributable to the approximately 190,000 ounces of gold sales discussed above.

For all of its other partially owned consolidated subsidiaries, FCX attributes net income or loss based on equity ownership percentages.

**Joint Ventures.** 

*Sumitomo and SMM Morenci, Inc.* FMC owns a 72% undivided interest in Morenci via an unincorporated joint venture. The remaining 28% is owned by Sumitomo (15%) and SMM Morenci, Inc. (13%). Each partner takes in kind its share of Morenci's production. FMC purchased 62 million pounds of Morenci's copper cathode from Sumitomo and SMM Morenci, Inc. at market prices for $245 million during 2022. FMC had receivables from Sumitomo and SMM Morenci, Inc. totaling $25 million at December 31, 2022, and $20 million at December 31, 2021.

*PT Smelting.* PT Smelting is an Indonesia company that owns a copper smelter and refinery in Gresik, Indonesia. In 1996, PT-FI entered into a joint venture and shareholder agreement with MMC to jointly construct the PT Smelting facilities. PT Smelting, which commenced operations in 1999, was the first and currently the only operating copper smelter facility in Indonesia. PT-FI owns 39.5% of the outstanding common stock of PT Smelting. MMC owns the remaining 60.5% of PT Smelting's outstanding common stock and serves as the operator of the facilities.

On November 30, 2021, PT-FI entered into a convertible loan agreement to fund an expansion of PT Smelting's facilities. Upon completion of the expansion project, targeted for year-end 2023, PT-FI's loan is expected to convert into PT Smelting equity resulting in a majority ownership interest.

FCX has determined that PT Smelting is a variable interest entity (VIE), however, as mutual consent of both PT-FI and MMC is required to make the decisions that most significantly impact the economic performance of PT Smelting, PT-FI is not the primary beneficiary. As PT-FI has the ability to exercise significant influence over PT Smelting, it accounts for its investment in PT Smelting under the equity method (refer to Note 6).

PT-FI's maximum exposure to loss is its investment in PT Smelting and its loan to fund the expansion (refer to Note 6). Additionally, refer to Note 6 for the carrying values of PT-FI's trade receivable balances from PT Smelting for sales of concentrate. PT-FI's equity in PT Smelting's earnings totaled $24 million in 2022, $6 million in 2021 and $11 million in 2020.

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

Beginning in 2023, PT-FI's commercial arrangement with PT Smelting converted to a tolling arrangement. Under the arrangement, PT-FI pays PT Smelting a tolling fee to smelt and refine its concentrate and will retain title to all products for sale to third parties (*i.e.,* there are no further sales from PT-FI to PT Smelting).

**NOTE 4. INVENTORIES, INCLUDING LONG-TERM MILL AND LEACH STOCKPILES**

The components of inventories follow:

---

a.Materials and supplies inventory was net of obsolescence reserves totaling $39 million at December 31, 2022, and $36 million at December 31, 2021.

b.Estimated metals in stockpiles not expected to be recovered within the next 12 months.

FCX recorded metal inventory adjustments totaling $29 million in 2022, including $19 million associated with NRV adjustments related to lower market prices for copper and $10 million for stockpile write-offs at Cerro Verde; $16 million in 2021, primarily associated with stockpiles at the Morenci mine no longer expected to be leached; and $96 million in 2020 associated with NRV adjustments related to lower market prices for copper and molybdenum. Refer to Note 16 for metal inventory adjustments by business segment.

**El Abra Stockpile Adjustment**. In 2022, the El Abra mine revised its estimated recovery rate assumptions for specific ore types expected to be processed from its existing leach stockpile. The revised estimates resulted in a 135 million pound reduction in future estimated recoverable copper from this leach stockpile, which is being phased out. This revised estimate did not have a significant impact on FCX's consolidated site production and delivery costs in 2022.

**Morenci Stockpile Adjustments.** The Morenci mine has experienced improved recoveries at certain of its leach stockpiles and following an analysis of column testing results in 2021, Morenci concluded it had sufficient evidence to increase its estimated recoveries for certain of its leach stockpiles. As a result of the revised recoveries, Morenci increased its estimated recoverable copper in leach stockpiles by 191 million pounds (net of joint venture interest). The effect of this change in estimate reduced FCX's consolidated site production and delivery costs and increased net income by $112 million ($0.08 per share) in 2021.

In 2022, based on an annual review of leach stockpiles, FCX increased its estimated recoverable copper in leach stockpiles at Morenci by 213 million pounds (net of joint venture interest). This revised estimate did not have a significant impact on FCX's consolidated site production and delivery costs in 2022.

**Revolving Credit Facilities**

*FCX*. At December 31, 2022, FCX had no borrowings outstanding and $8 million in letters of credit issued under its revolving credit facility and was in compliance with its revolving credit facility covenants.

In October 2022, FCX and PT-FI entered into a $3.0 billion, five-year, unsecured revolving credit facility, which replaced FCX's prior revolving credit facility that was scheduled to mature in April 2024. The revolving credit facility matures in October 2027. Under the terms of the revolving credit facility, FCX may obtain loans and issue letters of credit in an aggregate amount of up to $3.0 billion, with PT-FI's capacity limited to $500 million, and letters of credit issuance limited to $1.5 billion. Interest on loans made under the revolving credit facility may, at the option of FCX or PT-FI, be determined based on the Secured Overnight Financing Rate plus a spread to be determined by reference to a grid based on FCX's credit rating. The revolving credit facility contains customary affirmative covenants and representations, and also contains various negative covenants that, among other things and subject to certain exceptions, restrict the ability of FCX's subsidiaries that are not borrowers or guarantors to incur additional indebtedness (including guarantee obligations) and the ability of FCX or FCX's subsidiaries to: create liens on assets; enter into sale and leaseback transactions; engage in mergers, liquidations and dissolutions; and sell assets. In addition, the revolving credit facility contains a total leverage ratio financial covenant.

*PT-FI*. In July 2021, PT-FI entered into a $1.0 billion, five-year, unsecured credit facility to fund project costs in connection with the PT Smelting expansion and construction of a precious metals refinery (PMR), and for PT-FI's general corporate purposes. In April 2022, PT-FI amended and restated its five-year, unsecured revolving credit facility to, among other things, increase the availability to $1.3 billion. The amended and restated credit facility

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

matures in July 2026. At December 31, 2022, PT-FI had no borrowings under its revolving credit facility and was in compliance with its covenants.

PT-FI's revolving credit facility contains customary affirmative covenants and representations and also contains standard negative covenants that, among other things, restrict, subject to certain exceptions, the ability of PT-FI to incur additional indebtedness; create liens on assets; enter into sale and leaseback transactions; sell assets; and modify or amend the shareholders agreement or related governance structure. The credit facility also contains financial covenants governing maximum total leverage and minimum interest expense coverage and other covenants addressing certain environmental and social compliance requirements.

*Cerro Verde.* In May 2022, Cerro Verde entered into a $350 million, five-year, unsecured revolving credit

facility that matures in May 2027. At December 31, 2022, Cerro Verde had no borrowings outstanding under its revolving credit facility and was in compliance with its covenants.

**Pension Plans.** Following is a discussion of FCX's pension plans.

*FMC Plans.* FMC has U.S. trusteed, non-contributory pension plans covering some U.S. employees and some employees of its international subsidiaries hired before 2007. The applicable FMC plan design determines the manner in which benefits are calculated for any particular group of employees. Benefits are calculated based on final average monthly compensation and years of service or based on a fixed amount for each year of service. Non-bargained FMC employees hired after December 31, 2006, are not eligible to participate in the FMC U.S. pension

plan. In August 2020, the FMC Retirement Plan, the largest FMC plan, was amended such that, effective September 1, 2020, participants no longer accrue any additional benefits.

FCX's funding policy for these plans provides that contributions to pension trusts shall be at least equal to the minimum funding requirements of the Employee Retirement Income Security Act of 1974, as amended, for U.S. plans; or, in the case of international plans, the minimum legal requirements that may be applicable in the various countries. Additional contributions also may be made from time to time.

FCX's primary investment objectives for the FMC plan assets held in a master trust (Master Trust) are to maintain funds sufficient to pay all benefit and expense obligations when due, minimize the volatility of the plan's funded status to the extent practical, and to maintain prudent levels of risk consistent with the plan's investment policy. Historically, FMC plan assets have been invested in a balanced portfolio of return-seeking and risk-mitigating assets, with the allocation between these portfolios dependent on the funded status of the plan. During 2021, FCX reallocated essentially all of the portfolio to risk-mitigating assets with the objective of minimizing funded-status volatility. The risk-mitigating assets are allocated among multiple fixed income managers. The current target allocation of the portfolio is long-duration credit (50%); long-duration U.S. government/credit (20%); core fixed income (16%); long-term U.S. Treasury Separate Trading of Registered Interest and Principal Securities (STRIPS) (13%); and cash equivalents (1%).

The expected rate of return on plan assets is evaluated at least annually, taking into consideration asset allocation, historical and expected future performance on the types of assets held in the Master Trust, and the current economic environment. Based on these factors, FCX expects the pension assets will earn an average of 5% per annum beginning January 1, 2023, which is based on the target asset allocation and long-term capital market return expectations.

For estimation purposes, FCX assumes the long-term asset mix for these plans generally will be consistent with the current mix. Changes in the asset mix could impact the amount of recorded pension costs, the funded status of the plans and the need for future cash contributions. A lower-than-expected return on assets also would decrease plan assets and increase the amount of recorded pension costs in future years. When calculating the expected return on plan assets, FCX uses the market value of assets.

Among the assumptions used to estimate the pension benefit obligation is a discount rate used to calculate the present value of expected future benefit payments for service to date. The discount rate assumption for FCX's U.S. plans is designed to reflect yields on high-quality, fixed-income investments for a given duration. The determination of the discount rate for these plans is based on expected future benefit payments together with the Mercer Yield Curve - Above Mean. The Mercer Yield Curve - Above Mean is constructed from the bonds in the Mercer Pension Discount Curve that have a yield higher than the regression mean yield curve. The Mercer Yield Curve - Above Mean consists of spot (*i.e.*, zero coupon) interest rates at one-half-year increments for each of the next 30 years and is developed based on pricing and yield information for high-quality corporate bonds. Changes in the discount rate are reflected in FCX's benefit obligation and, therefore, in future pension costs.

*SERP Plan.* FCX has an unfunded Supplemental Executive Retirement Plan (SERP) for its chief executive officer. The SERP provides for retirement benefits payable in the form of a joint and survivor annuity, life annuity or an equivalent lump sum. The participant has elected to receive an equivalent lump sum payment. The payment will equal a percentage of the participant's highest average compensation for any consecutive three-year period during the five years immediately preceding the completion of 25 years of credited service. The SERP benefit will be reduced by the value of all benefits from current and former retirement plans (qualified and nonqualified) sponsored by FCX, by FM Services Company, FCX's wholly owned subsidiary, or by any predecessor employer (including FCX's former parent company), except for benefits produced by accounts funded exclusively by deductions from the participant's pay.

*PT-FI Plan.* PT-FI has a defined benefit pension plan denominated in Indonesia rupiah covering substantially all of its Indonesia national employees. PT-FI funds the plan and invests the assets in accordance with Indonesia pension guidelines. The pension obligation was valued at an exchange rate of 15,652 rupiah to one U.S. dollar on December 31, 2022, and 14,198 rupiah to one U.S. dollar on December 31, 2021. Indonesia labor laws require that companies provide a minimum severance to employees upon employment termination based on the reason for termination and the employee's years of service. PT-FI's pension benefit obligation includes benefits determined in accordance with this law. PT-FI's expected rate of return on plan assets is evaluated at least annually, taking into consideration its long-range estimated return for the plan based on the asset mix. Based on these factors, PT-FI

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

expects its pension assets will earn an average of 7% per annum beginning January 1, 2023. The discount rate assumption for PT-FI's plan is based on the Indonesia Government Security Yield Curve. Changes in the discount rate are reflected in PT-FI's benefit obligation and, therefore, in future pension costs.

*Plan Information.* FCX uses a measurement date of December 31 for its plans. Information for qualified and non-qualified plans where the projected benefit obligations and the accumulated benefit obligations exceed the fair value of plan assets follows:

a.Employer contributions for 2023 are currently expected to approximate $60 million for the FCX plans and $11 million for the PT-FI plan (based on a December 31, 2022, exchange rate of 15,652 Indonesia rupiah to one U.S. dollar).

During 2022, the actuarial gain of $623 million for the FCX pension plans primarily resulted from the increase in the discount rate from 2.85% to 5.41%. During 2021, the actuarial gain of $117 million for the FCX pension plans primarily resulted from the increase in the discount rate from 2.50% to 2.85%.

Plan assets are classified within a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1), then to prices derived using significant observable inputs (Level 2) and the lowest priority to prices derived using significant unobservable inputs (Level 3).

Following is a description of the pension plan asset categories included in the above tables and the valuation techniques used to measure fair value. There have been no changes to the techniques used to measure fair value.

Commingled/collective funds are managed by several fund managers and are valued at the NAV per unit of the fund. For most of these funds, the majority of the underlying assets are actively traded securities. These funds (except the real estate property fund) primarily require up to a two-business-day notice for redemptions. The real estate property fund is valued at NAV using information from independent appraisal firms, who have knowledge and expertise about the current market values of real property in the same vicinity as the investments.

Fixed income investments include corporate and government bonds held directly by the Master Trust. Fixed income securities are valued using a bid-evaluation price or a mid-evaluation price and, as such, are classified within Level 2 of the fair value hierarchy. A bid-evaluation price is an estimated price at which a dealer would pay for a security. A mid-evaluation price is the average of the estimated price at which a dealer would sell a security and the estimated price at which a dealer would pay for a security. These evaluations are based on quoted prices, if available, or models that use observable inputs.

Private equity investments are valued at NAV using information from general partners and have inherent restrictions on redemptions that may affect the ability to sell the investments at their NAV in the near term.

Following is a description of the valuation techniques used for pension plan assets measured at fair value associated with the PT-FI plan. There have been no changes to the techniques used to measure fair value.

Government bonds, common stocks and mutual funds are valued at the closing price reported on the active market on which the individual securities are traded and, as such, are classified within Level 1 of the fair value hierarchy.

The techniques described above may produce a fair value calculation that may not be indicative of NRV or reflective of future fair values. Furthermore, while FCX believes its valuation techniques are appropriate and consistent with those used by other market participants, the use of different techniques or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

**Postretirement and Other Benefits.** FCX also provides postretirement medical and life insurance benefits for certain U.S. employees and, in some cases, employees of certain international subsidiaries. These postretirement benefits vary among plans, and many plans require contributions from retirees. The expected cost of providing such postretirement benefits is accrued during the years employees render service.

The benefit obligation (funded status) for the postretirement medical and life insurance benefit plans consisted of a current portion of $6 million (included in accounts payable and accrued liabilities) and a long-term portion of $43 million (included in other liabilities) at December 31, 2022, and a current portion of $7 million and a long-term portion of $57 million at December 31, 2021.

FCX has a number of postemployment plans covering severance, long-term disability income, continuation of health and life insurance coverage for disabled employees or other welfare benefits. The accumulated postemployment benefit obligation consisted of a current portion of $7 million (included in accounts payable and accrued liabilities) and a long-term portion of $41 million (included in other liabilities) at December 31, 2022, and a current portion of $6 million and a long-term portion of $35 million at December 31, 2021.

FCX also sponsors a retirement savings plan for most of its U.S. employees. The plan allows employees to contribute a portion of their income in accordance with specified guidelines. The savings plan is a qualified 401(k) plan for all U.S. salaried and non-bargained hourly employees. Participants exercise control and direct the investment of their contributions and account balances among various investment options under the plan. FCX contributes to the plan and matches a percentage of employee contributions up to certain limits. For employees whose eligible compensation exceeds certain levels, FCX provides a nonqualified unfunded defined contribution plan, which had a liability balance of $56 million at December 31, 2022, and $51 million at December 31, 2021, all of which was included in other liabilities.

The costs charged to operations for the employee savings plan totaled $101 million in 2022, $95 million in 2021 and $40 million in 2020. The costs were lower in 2020, compared with 2022 and 2021, because of a temporary suspension of FCX contributions implemented as part of its April 2020 revised operating plans. FCX contributions resumed on January 1, 2021. FCX has other employee benefit plans, certain of which are related to FCX's financial results, which are recognized in operating costs.

**NOTE 10. STOCKHOLDERS' EQUITY AND STOCK-BASED COMPENSATION**

FCX's authorized shares of capital stock total 3.05 billion shares, consisting of 3.0 billion shares of common stock and 50 million shares of preferred stock.

**Financial Policy.** In February 2021, FCX's Board of Directors (Board) adopted a financial policy for the allocation of cash flows aligned with FCX's strategic objectives of maintaining a strong balance sheet and increasing cash returns to shareholders while advancing opportunities for future growth. The policy includes a base dividend and a performance-based payout framework, whereby up to 50% of available cash flows generated after planned capital spending and distributions to noncontrolling interests would be allocated to shareholder returns and the balance to debt reduction and investments in value enhancing growth projects, subject to FCX maintaining its net debt at a level not to exceed the net debt target of $3.0 billion to $4.0 billion (excluding project net debt for additional smelting capacity in Indonesia).

In February 2021, the Board reinstated a cash dividend on FCX's common stock (base dividend), and on November 1, 2021, the Board approved (i) a new share repurchase program authorizing repurchases of up to $3.0 billion of FCX common stock and (ii) a variable cash dividend on FCX's common stock for 2022. In July 2022, the Board authorized an increase in the share repurchase program from up to $3.0 billion to up to $5.0 billion. Refer to Note 11 for further discussion of the U.S. Inflation Reduction Act (the Act), including a 1% excise tax on corporate stock repurchases beginning in 2023.

In 2021, FCX acquired 12.74 million shares of its common stock for a total cost of $0.5 billion ($38.32 average cost per share) and in 2022, FCX acquired 35.12 million shares of its common stock under its share repurchase program for a total cost of $1.3 billion ($38.36 average cost per share). As of February 15, 2023, FCX has $3.2 billion available for repurchases under the program.

On December 21, 2022, FCX declared quarterly cash dividends totaling $0.15 per share ($0.075 per share base dividend and $0.075 per share variable dividend) on its common stock, which were paid on February 1, 2023, to common stockholders of record as of January 13, 2023.

The declaration and payment of dividends (base or variable) and timing and amount of any share repurchases is at the discretion of FCX's Board and management, respectively, and is subject to a number of factors, including maintaining FCX's net debt target, capital availability, FCX's financial results, cash requirements, global economic conditions, changes in laws, contractual restrictions and other factors deemed relevant by FCX's Board or management, as applicable. FCX's share repurchase program may be modified, increased, suspended or terminated at any time at the Board's discretion.

**Stock Award Plans.** FCX currently has awards outstanding under various stock-based compensation plans. The stockholder-approved 2016 Stock Incentive Plan (the 2016 Plan) provides for the issuance of stock options, stock appreciation rights, restricted stock, RSUs, PSUs and other stock-based awards for up to 72 million common shares. As of December 31, 2022, 25.5 million shares were available for grant under the 2016 Plan, and no shares were available under other plans.

a. Charges in the U.S. are not expected to generate a future tax benefit.

*Stock Options.* Stock options granted under the plans generally expire 10 years after the date of grant. Stock options vest in one-third annual increments beginning one year from the date of grant. The award agreements provide that participants will receive the following year's vesting upon retirement. Therefore, on the date of grant, FCX accelerates one year of amortization for retirement-eligible employees. The award agreements also provide for accelerated vesting upon certain qualifying terminations of employment within one year following a change of control. There were no stock options granted by FCX in 2022.

The fair value of each stock option is estimated on the date of grant using the Black-Scholes-Merton option valuation model. Expected volatility is based on implied volatilities from traded options on FCX's common stock and historical volatility of FCX's common stock. FCX uses historical data to estimate future option exercises, forfeitures and expected life. When appropriate, separate groups of employees who have similar historical exercise behavior are considered separately for valuation purposes. The expected dividend rate is calculated using the expected annual dividend at the date of grant. The risk-free interest rate is based on Federal Reserve rates in effect for bonds with maturity dates equal to the expected term of the option.

a. FCX did not grant stock options in 2022.

*Stock-Settled PSUs and RSUs.* Since 2014, FCX's executive officers received annual grants of PSUs that vest after a three-year performance period. The total grant date target shares related to the PSU grants were 0.4 million for 2022, 0.3 million for 2021 and 0.8 million for 2020, of which the executive officers will earn (i) between 0% and 200% of the target shares based on achievement of financial metrics and (ii) may be increased or decreased up to 25% of the target shares based on FCX's total shareholder return compared to the total shareholder return of a peer group. PSU awards for FCX's executive officers who are retirement-eligible are non-forfeitable. As such, FCX charges the estimated fair value of the non-forfeitable PSU awards to expense at the time the financial and operational metrics are established, which is typically grant date. The fair value of PSU awards for FCX's executive officers who are not retirement-eligible are expensed over the performance period.

FCX grants RSUs that vest over a period of three years or at the end of three years to certain employees. Some award agreements allow for participants to receive the following year's vesting upon retirement. Therefore, on the date of grant of these RSU awards, FCX accelerates one year of amortization for retirement-eligible employees. FCX also grants RSUs to its directors, which vest on the first anniversary of the date of grant. The fair value of the RSUs is amortized over the vesting period or the period until the director becomes retirement eligible, whichever is shorter. Upon a director's retirement, all of their unvested RSUs immediately vest. For retirement-eligible directors, the fair value of RSUs is recognized in earnings on the date of grant.

The award agreements provide for accelerated vesting of all RSUs held by directors if there is a change of control (as defined in the award agreements) and for accelerated vesting of all RSUs held by employees if they experience a qualifying termination within one year following a change of control.

Dividends attributable to RSUs and PSUs accrue and are paid if the awards vest. A summary of outstanding stock-settled RSUs and PSUs as of December 31, 2022, and activity during the year ended December 31, 2022, follows:

---

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

The total fair value of stock-settled RSUs and PSUs granted was $83 million during 2022, $62 million during 2021 and $47 million during 2020. The total intrinsic value of stock-settled RSUs and PSUs vested was $138 million during 2022, $56 million during 2021 and $18 million during 2020. As of December 31, 2022, FCX had $25 million of total unrecognized compensation cost related to unvested stock-settled RSUs and PSUs expected to be recognized over approximately 1.2 years.

*Cash-Settled RSUs.* Cash-settled RSUs are similar to stock-settled RSUs, but are settled in cash rather than in shares of common stock. These cash-settled RSUs generally vest over three years of service. Some award agreements allow for participants to receive the following year's vesting upon retirement. Therefore, on the date of grant of these cash-settled RSU awards, FCX accelerates one year of amortization for retirement-eligible employees. The cash-settled RSUs are classified as liability awards, and the fair value of these awards is remeasured each reporting period until the vesting dates. The award agreements for cash-settled RSUs provide for accelerated vesting upon certain qualifying terminations of employment within one year following a change of control.

Dividends attributable to cash-settled RSUs accrue and are paid if the awards vest. A summary of outstanding cash-settled RSUs as of December 31, 2022, and activity during the year ended December 31, 2022, follows:

The total grant-date fair value of cash-settled RSUs was $15 million during 2022, $9 million during 2021 and $11 million during 2020. The intrinsic value of cash-settled RSUs vested was $26 million during 2022, $24 million during 2021 and $11 million during 2020. The accrued liability associated with cash-settled RSUs consisted of a current portion of $19 million (included in accounts payable and accrued liabilities) and a long-term portion of $5 million (included in other liabilities) at December 31, 2022, and a current portion of $26 million and a long-term portion of $6 million at December 31, 2021.

Income taxes are provided on the earnings of FCX's material foreign subsidiaries under the assumption that these earnings will be distributed. FCX has not provided deferred income taxes for other differences between the book and tax carrying amounts of its investments in material foreign subsidiaries as FCX considers its ownership positions to be permanent in duration, and quantification of the related deferred tax liability is not practicable.

**Tax Attributes.** At December 31, 2022, FCX had (i) U.S. foreign tax credits of $1.5 billion that will expire between 2023 and 2027, (ii) U.S. federal NOLs of $5.5 billion that primarily expire between 2036 and 2037, of which $0.4 billion can be carried forward indefinitely, (iii) U.S. state NOLs of $10.5 billion that primarily expire between 2023 and 2042, (iv) Spanish NOLs of $0.5 billion that can be carried forward indefinitely and (v) Indonesia NOLs of $0.5 billion that expire between 2024 and 2026.

**Valuation Allowances.** On the basis of available information at December 31, 2022, including positive and negative evidence, FCX has provided valuation allowances for certain of its deferred tax assets where it believes it is more-likely-than-not that some portion or all of such assets will not be realized. Valuation allowances totaled $4.0 billion at December 31, 2022, and covered all of FCX's U.S. foreign tax credits and U.S. federal NOLs, substantially all of its U.S. state NOLs, as well as a portion of its U.S. federal, state and foreign deferred tax assets and foreign NOLs.

The valuation allowance related to FCX's U.S. foreign tax credits totaled $1.5 billion at December 31, 2022. FCX has operations in tax jurisdictions where statutory income taxes and withholding taxes are in excess of the U.S. federal income tax rate. Valuation allowances are recognized on foreign tax credits for which no benefit is expected to be realized.

The valuation allowance related to FCX's U.S. federal, state and foreign NOLs totaled $1.8 billion and other deferred tax assets totaled $0.7 billion at December 31, 2022. NOLs and deferred tax assets represent future deductions for which a benefit will only be realized to the extent these deductions offset future income. FCX develops an estimate of which future tax deductions will be realized and recognizes a valuation allowance to the extent these deductions are not expected to be realized in future periods.

Valuation allowances will continue to be carried on U.S. foreign tax credits, U.S. federal, state and foreign NOLs and U.S. federal, state and foreign deferred tax assets, until such time that (i) FCX generates taxable income against which any of the assets, credits or NOLs can be used, (ii) forecasts of future income provide sufficient positive evidence to support reversal of the valuation allowances or (iii) FCX identifies a prudent and feasible means of securing the benefit of the assets, credits or NOLs that can be implemented.

The $102 million net decrease in the valuation allowances during 2022 is primarily related to $163 million of U.S. federal NOLs utilized during 2022, and a $22 million decrease related to expirations of U.S. foreign tax credits partially offset by an increase of $104 million, primarily associated with current year changes in U.S. federal temporary differences.

**U.S. Inflation Reduction Act of 2022**. In August 2022, the Act was signed into law, which includes, among other provisions, a new Corporate Alternative Minimum Tax (CAMT) of 15% on the adjusted financial statement income (AFSI) of corporations with average AFSI exceeding $1.0 billion over a three-year period, and a new excise tax of 1% on the fair market value of net corporate stock repurchases. The Act had no impact on FCX's consolidated financial statements for the year ended December 31, 2022. The provisions of the Act are applicable to FCX beginning January 1, 2023. Additional guidance related to how the CAMT provisions of the Act will be applied or otherwise administered is yet to be released by the U.S. Department of the Treasury, and may differ from FCX's interpretations. FCX will continue to analyze the impacts as additional guidance is released. FCX expects the CAMT provisions will impact its U.S. tax position, and may further limit its ability to benefit from its U.S. NOLs.

**Other Events.** In connection with the negative impacts of the COVID-19 pandemic on the global economy, governments throughout the world announced measures that are intended to provide tax and other financial relief. Such measures include the American Rescue Plan Act of 2021, enacted in March 2021, and the Coronavirus Aid, Relief, and Economic Security Act (CARES Act), enacted in March 2020. None of these measures resulted in material impacts to FCX's provision for income taxes for the years ended December 31, 2021 or 2020. However, certain provisions of the CARES Act provided FCX with the opportunity to accelerate collections of tax refunds, primarily those associated with the U.S. alternative minimum tax (AMT). FCX fully collected all outstanding U.S. AMT refunds of $24 million in 2021 and $244 million in 2020.

**Indonesia Tax Matters.** In 2018, PT-FI received unfavorable Indonesia Tax Court decisions with respect to its appeal of capitalized mine development costs on its 2012 and 2014 corporate income tax returns. PT-FI appealed those decisions to the Indonesia Supreme Court. In 2019, the Indonesia Supreme Court communicated an unfavorable ruling regarding the treatment of mine development costs on PT-FI's 2014 tax return. During fourth-quarter 2019, PT-FI met with the Indonesia Tax Office and developed a framework for resolution of the disputed matters. On December 30, 2019, PT-FI made a payment of $250 million based on its understanding of the framework for resolution of disputes arising from the audits of the tax years 2012 through 2016, as well as tax years 2017 and 2018, and recorded net charges totaling $304 million for the year 2019.

During 2020, in connection with progress of the framework for resolution of the disputed matters, PT-FI recorded additional net charges of $46 million, including $9 million for non-deductible penalties recorded to other (expense) income, net and $35 million for non-deductible interest recorded to interest expense, net, and $2 million to provision for income tax expense.

During 2021, PT-FI participated in discussions with the Indonesia Tax Office regarding progress on the framework for resolution of disputes arising from the audits of tax years 2012 through 2016. As a result of these discussions and the revised positions taken by both the Indonesia Tax Office and PT-FI, FCX could no longer conclude a resolution of all of the disputed tax items at a more-likely-than-not threshold and PT-FI recorded additional net charges of $384 million, including $155 million for non-deductible penalties recorded to other income (expense), net, $43 million for non-deductible interest recorded to interest expense, net, and $186 million to provision for income tax expense.

During 2022, in conjunction with the framework for resolution of disputed matters and the closure of the 2018 corporate income tax audit, PT-FI recorded net charges of $13 million, including $5 million for non-deductible interest recorded to interest expense, net, and $8 million to provision for income taxes. PT-FI continues to engage with the Indonesia Tax Office in pursuit of clarification on certain aspects of the original framework for resolution of the disputed matters.

In conjunction with the issuance of Government Regulation Number 50 of 2022, which stipulates that objection, tax court, and judicial review verdicts issued after the issuance of the harmonization law qualify for reduced penalties, PT-FI recorded net credits totaling $69 million in 2022 (including a credit of $76 million recorded to other income (expense), net and a charge of $7 million to provision for income taxes), which mostly related to the disputed matters discussed above.

**Peru Tax Matters.** In 2016, the Peru parliament passed tax legislation that, in part, modified the applicable tax rates established in its 2014 tax legislation, which progressively decreased the corporate income tax rate to 26% in 2019 and thereafter, and also increased the dividend tax rate on distributions to 9.3% in 2019 and thereafter. Under the tax legislation, which was effective January 1, 2017, the corporate income tax rate was 29.5%, and the dividend tax rate on distributions of earnings was 5%. Cerro Verde's current mining stability agreement subjects it to a stable

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

income tax rate of 32% through the expiration of the agreement on December 31, 2028. The tax rate on dividend distributions is not stabilized by the agreement.

**Chile Tax Matters**. In 2014, the Chile legislature approved a tax reform package that implemented a dual tax system, which was amended in 2016. Under previous rules, FCX's share of income from El Abra was subject to an effective 35% tax rate allocated between income taxes and dividend withholding taxes. Under the amended tax reform package, El Abra is subject to the "Partially-Integrated System," resulting in FCX's share of income from El Abra being subject to progressively increasing effective tax rates of 35% through 2019 and 44.5% in 2020 and thereafter. In 2017, the progression of increasing tax rates was delayed by the Chile legislature so that the 35% rate continued through 2021, increasing to 44.5% in 2022 and thereafter. In January 2020, the Chile legislature approved a tax reform package that would further delay the 44.5% rate until 2027 and thereafter.

In 2010, the Chile legislature approved an increase in mining royalty taxes to help fund earthquake reconstruction activities, education and health programs. Beginning in 2018, and through 2023 mining royalty rates at FCX's El Abra mine are based on a sliding scale of 5% to 14% (depending on a defined operational margin).

**Uncertain Tax Positions.** Tax positions reflected in the consolidated financial statements are based on their technical merits, more-likely-than-not to be sustained upon examination by taxing authorities or have otherwise been effectively settled. Such tax positions reflect the largest amount of benefit, determined on a cumulative probability basis, that is more-likely-than-not to be realized upon settlement with the applicable taxing authority with full knowledge of all relevant information. FCX's policy associated with uncertain tax positions is to record accrued interest in interest expense and accrued penalties in other income (expense), net rather than in the provision for income taxes.

A summary of the activities associated with FCX's reserve for unrecognized tax benefits for the years ended December 31 follows.

The total amount of accrued interest and penalties associated with unrecognized tax benefits was $551 million at December 31, 2022, primarily relating to unrecognized tax benefits associated with cost recovery methods and royalties and other related mining taxes, $620 million at December 31, 2021, and $307 million at December 31, 2020.

The reserve for unrecognized tax benefits of $810 million at December 31, 2022, included $689 million ($485 million net of income tax benefits and valuation allowances) that, if recognized, would reduce FCX's provision for income taxes. Changes in the reserve for unrecognized tax benefits associated with current and prior-year tax positions were primarily related to uncertainties associated with FCX's tax treatment of cost recovery methods and various non-deductible costs. There continues to be uncertainty related to the timing of settlements with taxing authorities, but if additional settlements are agreed upon during the year 2023, FCX could experience a change in its reserve for unrecognized tax benefits.

**NOTE 12. CONTINGENCIES**

**Environmental.** FCX subsidiaries are subject to various national, state and local environmental laws and regulations that govern emissions of air pollutants; discharges of water pollutants; generation, handling, storage and disposal of hazardous substances, hazardous wastes and other toxic materials; and remediation, restoration and reclamation of environmental contamination. FCX subsidiaries that operate in the U.S. also are subject to potential liabilities arising under CERCLA and similar state laws that impose responsibility on current and previous owners and operators of a facility for the remediation of hazardous substances released from the facility into the environment, including damages to natural resources, in some cases irrespective of when the damage to the environment occurred or who caused it. Remediation liability also extends to persons who arranged for the disposal of hazardous substances or transported the hazardous substances to a disposal site selected by the transporter. These liabilities are often shared on a joint and several basis, meaning that each responsible party is fully responsible for the remediation if some or all of the other historical owners or operators no longer exist, do not have the financial ability to respond or cannot be found. As a result, because of FCX's acquisition of FMC, many of the subsidiary companies FCX now owns are responsible for a wide variety of environmental remediation projects throughout the U.S., and FCX expects to spend substantial sums annually for many years to address those remediation issues. Certain FCX subsidiaries have been advised by the U.S. Environmental Protection Agency (EPA), the Department of the Interior, the Department of Agriculture and various state agencies that, under CERCLA or similar state laws and regulations, they may be liable for costs of responding to environmental conditions at a number of sites that have been or are being investigated to determine whether releases of hazardous substances have occurred and, if so, to develop and implement remedial actions to address environmental concerns. FCX is also subject to claims where the release of hazardous substances is alleged to have damaged natural resources (NRD) and to litigation by individuals allegedly exposed to hazardous substances. As of December 31, 2022, FCX had more than 100 active remediation projects, including NRD claims, in 24 U.S. states. The aggregate environmental obligation for approximately 60% of the active remediation projects totaled less than $20 million at December 31, 2022.

A summary of changes in estimated environmental obligations for the years ended December 31 follows:

a.Represents accretion of the fair value of environmental obligations assumed in the acquisition of FMC, which were determined on a discounted cash flow basis.

b.Adjustments to environmental obligations are charged to operating income. Adjustments primarily reflect revisions for changes in the anticipated scope and timing of projects and other noncash adjustments.

Estimated future environmental cash payments (on an undiscounted and de-escalated basis) total $3.7 billion, including $125 million in 2023, $120 million in 2024, $93 million in 2025, $100 million in 2026, $97 million in 2027 and $3.2 billion thereafter. The amount and timing of these estimated payments will change as a result of changes in regulatory requirements, changes in scope and timing of remediation activities, the settlement of environmental matters and as actual spending occurs.

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

At December 31, 2022, FCX's environmental obligations totaled $1.7 billion, including $1.6 billion recorded on a discounted basis for those obligations assumed in the FMC acquisition at fair value. FCX estimates it is reasonably possible that these obligations could range between $3.3 billion and $4.1 billion on an undiscounted and de-escalated basis.

At December 31, 2022, the most significant environmental obligations were associated with the Pinal Creek site in Arizona; the Newtown Creek site in New York City; historical smelter sites principally located in Arizona, Indiana, Kansas, Missouri, New Jersey, Oklahoma and Pennsylvania; and uranium mining sites in the western U.S. The recorded environmental obligations for these sites totaled $1.5 billion at December 31, 2022. FCX may also be subject to litigation brought by private parties, regulators and local governmental authorities related to these historical sites. A discussion of these sites follows.

*Pinal Creek.* The Pinal Creek site was listed under the Arizona Department of Environmental Quality's (ADEQ) Water Quality Assurance Revolving Fund program in 1989 for contamination in the shallow alluvial aquifers within the Pinal Creek drainage near Miami, Arizona. Since that time, environmental remediation has been performed by members of the Pinal Creek Group, consisting of Freeport-McMoRan Miami Inc. (Miami), an indirect wholly owned subsidiary of FCX, and two other companies. Pursuant to a 2010 settlement agreement, Miami agreed to take full responsibility for future groundwater remediation at the Pinal Creek site, with limited exceptions. Remediation work consisting of groundwater extraction and treatment plus source control capping is expected to continue for many years. FCX's environmental liability balance for this site was $437 million at December 31, 2022.

*Newtown Creek.* From the 1930s until 1964, Phelps Dodge Refining Corporation (PDRC), an indirect wholly owned subsidiary of FCX, operated a copper smelter, and from the 1930s until 1984, a copper refinery, on the banks of Newtown Creek (the creek), which is a 3.5-mile-long waterway that forms part of the boundary between Brooklyn and Queens in New York City. Heavy industrial uses on and around the creek and discharges from the City of New York's sewer system over more than a century resulted in significant environmental contamination of the waterway. In 2010, EPA notified PDRC, four other companies and the City of New York that EPA considers them PRPs under CERCLA. The notified parties began working with EPA to identify other PRPs. In 2010, EPA designated the creek as a Superfund site, and in 2011, PDRC and four other companies (the Newtown Creek Group, NCG) and the City of New York entered an Administrative Order on Consent to perform a remedial investigation/feasibility study (RI/FS) to assess the nature and extent of environmental contamination in the creek and identify remedial options. The NCG's RI/FS work and efforts to identify other PRPs are ongoing. The NCG submitted a final draft RI report to EPA in December 2022. The NCG expects to submit a draft FS report to EPA in late 2025 and currently expects EPA to select a creek-wide remedy in 2028, with the actual remediation construction starting several years later. In early 2022, EPA asked the NCG to develop and evaluate remedial alternatives for an early action in the East Branch tributary of the creek. FCX's environmental liability balance for this site was $338 million at December 31, 2022. The final costs of fulfilling this remedial obligation and the allocation of costs among PRPs are uncertain and subject to change based on the results of the RI/FS, the remedy ultimately selected by EPA and related allocation determinations. Changes to the overall cost of this remedial obligation and the portion ultimately allocated to PDRC could be material to FCX.

*Historical Smelter Sites*. FCX subsidiaries and their predecessors at various times owned or operated copper, zinc and lead smelters or refineries in states including Arizona, Indiana, Kansas, Missouri, New Jersey, Oklahoma and Pennsylvania. For some of these former processing sites, certain FCX subsidiaries have been advised by EPA or state agencies that they may be liable for costs of investigating and, if appropriate, remediating environmental conditions associated with these former processing facilities. At other sites, certain FCX subsidiaries have entered into state voluntary remediation programs to investigate and, if appropriate, remediate on-site and off-site conditions associated with the facilities. The historical processing sites are in various stages of assessment and remediation. At some of these sites, disputes with local residents and elected officials regarding alleged health effects or the effectiveness of remediation efforts have resulted in litigation of various types, and similar litigation at other sites is possible.

From 1920 until 1986, United States Metals Refining Company (USMR), an indirect wholly owned subsidiary of FCX, owned and operated a copper smelter and refinery in the Borough of Carteret, New Jersey. Since the early 1980s, the site has been the subject of environmental investigation and remediation, under the direction and supervision of the New Jersey Department of Environmental Protection (NJDEP). On-site contamination is in the later stages of remediation. In 2012, after receiving a request from NJDEP, USMR also began investigating and remediating off-site properties, which is ongoing. As a result of off-site soil sampling in public and private areas near the former Carteret smelter, FCX established an environmental obligation for known and potential off-site

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

environmental remediation. Assessments of sediments in the adjacent Arthur Kill and sampling and analysis within the offsite area as we obtain access to residential properties are ongoing and could result in additional adjustments to the related environmental remediation obligation in future periods. The extent of contamination and potential remedial actions are uncertain and may take several years to evaluate.

FCX's environmental liability balance for historical smelter sites, including in the Borough of Carteret, New Jersey, was $268 million at December 31, 2022.

On January 30, 2017, a putative class action titled <u>Juan Duarte, Betsy Duarte and N.D., Infant, by Parents and Natural Guardians Juan Duarte and Betsy Duarte, Leroy Nobles and Betty Nobles, on behalf of themselves and all others similarly situated v. United States Metals Refining Company, Freeport-McMoRan Copper & Gold Inc. and Amax Realty Development, Inc.</u>, Docket No. 734-17, was filed in the Superior Court of New Jersey against USMR, FCX, and Amax Realty Development, Inc. The defendants removed this litigation to the U.S. District Court for the District of New Jersey, where it remains pending, and FMC was added as a defendant. The suit alleges that USMR generated and disposed of smelter waste at the site and allegedly released contaminants on-site and off-site through discharges to surface water and air emissions over a period of decades and seeks unspecified compensatory and punitive damages for economic losses, including diminished property values, additional soil investigation and remediation and other damages. In September 2022, the parties completed re-briefing on the plaintiffs' motion for class certification. The judge indicated in late 2022 that there likely would not be a decision on class certification until late 2023 or 2024. In December 2022, the parties reached an agreement in principle to settle the class action suit and individual claims by some property owners outside the settlement class area. The potential settlement (if effected in accordance with the agreement in principle) would not have a material effect on our financial condition, results of operations or cash flows. However, there can be no assurance that a settlement will be reached and, if an agreement among the parties is reached, the implementation of a settlement would require, among other things, court approval. Given the uncertainties and complexities involved, FCX continues to prepare for trial and intends to vigorously defend the matter.

*Uranium Mining Sites.* During a period between 1940 and the early 1980s, certain FCX subsidiaries and their predecessors were involved in uranium exploration and mining in the western U.S., primarily on federal and tribal lands in the Four Corners region of the southwest. Similar exploration and mining activities by other companies have also caused environmental impacts warranting remediation.

In 2017, the Department of Justice, EPA, Navajo Nation, and two FCX subsidiaries reached an agreement regarding the financial contribution of the U.S. Government and the FCX subsidiaries and the scope of the environmental investigation and remediation work for 94 former uranium mining sites on tribal lands. Under the terms of the Consent Decree executed in May 2017, and approved by the U.S. District Court for the District of Arizona, the U.S. contributed $335 million into a trust fund to cover the government's initial share of the costs, and FCX's subsidiaries are proceeding with the environmental investigation and remediation work at the 94 sites. The program is expected to take more than 20 years to complete. In 2020, FCX reduced its associated obligation and recorded a $47 million credit to operating income to reflect the discounting effect of the recent and expected pace of project work under post-COVID-19 pandemic conditions. By letter dated September 29, 2021, EPA informed an FCX subsidiary that it does not expect to have funds sufficient to remediate sites covered by a bankruptcy settlement with Tronox and EPA considers a subsidiary of FCX to be potentially liable for 23 of these sites. However, based on recently available information from EPA, it is currently considered unlikely that EPA will deplete the available settlement dollars, at least in the near-term, and seek additional funds from FCX.

FCX is also conducting site surveys of historical uranium mining claims associated with FCX subsidiaries on non-tribal federal lands in the Four Corners region. Under a memorandum of understanding with the U.S. Bureau of Land Management (BLM), site surveys are being performed on approximately 15,000 mining claims, ranging from undisturbed claims to claims with mining features. Based on these surveys, BLM has issued no further action determinations for certain undisturbed claims. A similar agreement is in place with the U.S. Forest Service for mine features on U.S. Forest Service land. Either BLM or the U.S. Forest Service may request additional assessment or remediation activities for other claims with mining features. FCX will update this obligation when it has a sufficient number of remedy decisions from the BLM or the U.S. Forest Service to support a reasonably certain range of outcomes. FCX expects it will take several years to complete this work.

FCX's environmental liability balance for the uranium mining sites was $439 million at December 31, 2022.

---

a.Includes adjustments at PT-FI, Morenci and Bagdad totaling $314 million for the year 2022 and adjustments at PT-FI totaling $397 million for the year 2021, see further discussion below.

ARO costs may increase or decrease significantly in the future as a result of changes in regulations, changes in engineering designs and technology, permit modifications or updates, changes in mine plans, settlements, inflation or other factors and as reclamation (concurrent with mining operations or post mining) spending occurs. ARO activities and expenditures for mining operations generally are made over an extended period of time commencing near the end of the mine life; however, certain reclamation activities may be accelerated if legally required or if determined to be economically beneficial. The methods used or required to plug and abandon non-producing oil and gas wellbores; remove platforms, tanks, production equipment and flow lines; and restore wellsites could change over time.

*Financial Assurance.* New Mexico, Arizona, Colorado and other states, as well as federal regulations governing mine operations on federal land, require financial assurance to be provided for the estimated costs of mine reclamation and closure, including groundwater quality protection programs. FCX has satisfied financial assurance requirements by using a variety of mechanisms, primarily involving parent company performance guarantees and financial capability demonstrations, but also including trust funds, surety bonds, letters of credit and other collateral. The applicable regulations specify financial strength tests that are designed to confirm a company's or guarantor's financial capability to fund estimated reclamation and closure costs. The amount of financial assurance FCX subsidiaries are required to provide will vary with changes in laws, regulations, reclamation and closure requirements, and cost estimates. At December 31, 2022, FCX's financial assurance obligations associated with these U.S. mine closure and reclamation/restoration costs totaled $1.5 billion, of which $0.9 billion was in the form of guarantees issued by FCX and FMC. At December 31, 2022, FCX had trust assets totaling $0.2 billion (included in other assets), which are legally restricted to be used to satisfy its financial assurance obligations for its mining properties in New Mexico. In addition, FCX subsidiaries have financial assurance obligations for its oil and gas properties associated with plugging and abandoning wells and facilities totaling $0.4 billion. Where oil and gas guarantees associated with the Bureau of Ocean Energy Management do not include a stated cap, the amounts reflect management's estimates of the potential exposure.

*New Mexico Environmental and Reclamation Programs.* FCX's New Mexico operations are regulated under the New Mexico Water Quality Act and regulations adopted by the Water Quality Control Commission. In connection with discharge permits, the New Mexico Environment Department (NMED) has required each of these operations to submit closure plans for NMED's approval. The closure plans must include measures to assure meeting applicable groundwater quality standards following the closure of discharging facilities and to abate groundwater or surface water contamination to meet applicable standards. FCX's New Mexico operations also are subject to regulation under the 1993 New Mexico Mining Act (the Mining Act) and the related rules that are administered by the Mining and Minerals Division of the New Mexico Energy, Minerals and Natural Resources Department. Under the Mining Act, mines are required to obtain approval of reclamation plans. The agencies approved updates to the closure plan and financial assurance instruments and completed a permit renewal for Chino in 2020 and Tyrone in 2021. At December 31, 2022, FCX had accrued reclamation and closure costs of $534 million for its New Mexico operations. Additional accruals may be required based on the state's periodic review of FCX's updated closure plans and any resulting permit conditions, and the amount of those accruals could be material.

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

*Arizona Environmental and Reclamation Programs.* FCX's Arizona operations are subject to regulatory oversight by the ADEQ. ADEQ has adopted regulations for its aquifer protection permit (APP) program that require permits for, among other things, certain facilities, activities and structures used for mining, leaching, concentrating and smelting, and require compliance with aquifer water quality standards during operations and closure. An application for an APP requires a proposed closure strategy that will meet applicable groundwater protection requirements following cessation of operations and an estimate of the implementation cost, with a more detailed closure plan required at the time operations cease. A permit applicant must demonstrate its financial ability to meet the closure costs approved by ADEQ. Closure costs for facilities covered by APPs are required to be updated every six years and financial assurance mechanisms are required to be updated every two years. During 2022, the Morenci and Bagdad mines increased their AROs by $118 million and $65 million, respectively, associated with their updated closure strategies and plans for stockpiles and tailings impoundments that were submitted to ADEQ for approval. FCX will continue evaluating and, as necessary, updating its closure plans and closure cost estimates at other Arizona sites, and any such updates may also result in increased costs that could be significant.

Portions of Arizona mining facilities that operated after January 1, 1986, also are subject to the Arizona Mined Land Reclamation Act (AMLRA). AMLRA requires reclamation to achieve stability and safety consistent with post-mining land use objectives specified in a reclamation plan. Reclamation plans must be approved by the State Mine Inspector and must include an estimate of the cost to perform the reclamation measures specified in the plan along with financial assurance. FCX will continue to evaluate options for future reclamation and closure activities at its operating and non-operating sites, which are likely to result in adjustments to FCX's AROs, and those adjustments could be material.

At December 31, 2022, FCX had accrued reclamation and closure costs of $581 million for its Arizona operations.

*Colorado Reclamation Programs.* FCX's Colorado operations are regulated by the Colorado Mined Land Reclamation Act (Reclamation Act) and regulations promulgated thereunder. Under the Reclamation Act, mines are required to obtain approval of plans for reclamation of lands affected by mining operations to be performed during mining or upon cessation of mining operations. In March 2020, the Division of Reclamation, Mining, and Safety (DRMS) approved Henderson's proposed update to its closure plan and closure cost estimate.

In 2019, Colorado enacted legislation that requires proof of an end date for water treatment as a condition of permit authorizations for new mining operations and expansions beyond current permit authorizations. While this requirement does not apply to existing operations, it may lead to changes in long-term water management requirements at Climax and Henderson operations and AROs. In accordance with its permit from DRMS, Climax will submit an updated reclamation plan and cost estimate in 2024.

As of December 31, 2022, FCX had accrued reclamation and closure costs of $162 million for its Colorado operations

*Chile Reclamation and Closure Programs.* El Abra is subject to regulation under the Mine Closure Law administered by the Chile Mining and Geology Agency. In compliance with the requirement for five-year updates, in November 2018, El Abra submitted an updated plan with closure cost estimates based on the existing approved closure plan. Approval of the updated closure plan and cost estimates was received in August 2020, and did not result in a material increase to closure costs. At December 31, 2022, FCX had accrued reclamation and closure costs of $98 million for its El Abra operation.

*Peru Reclamation and Closure Programs*. Cerro Verde is subject to regulation under the Mine Closure Law administered by the Peru Ministry of Energy and Mines. Under the closure regulations, mines must submit a closure plan that includes the reclamation methods, closure cost estimates, methods of control and verification, closure and post-closure plans, and financial assurance. In compliance with the requirement for five-year updates, Cerro Verde is preparing to submit its updated closure plan and cost estimate in February 2023. At December 31, 2022, FCX had accrued reclamation and closure costs of $171 million for its Cerro Verde operation, which includes preliminary cost estimates associated with Cerro Verde's updated closure plan.

*Indonesia Reclamation and Closure Programs.* The ultimate amount of reclamation and closure costs to be incurred at PT-FI's operations will be determined based on applicable laws and regulations and PT-FI's assessment of appropriate remedial activities under the circumstances, after consultation with governmental authorities, affected local residents and other affected parties and cannot currently be projected with precision. Some reclamation costs

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

will be incurred during mining activities, while the remaining reclamation costs will be incurred at the end of mining activities, which are currently estimated to continue through 2041. In 2021, the construction time frame for reclamation of the West Wanagon overburden stockpile was extended from 2025 to 2029 because safety constraints for working in steep and difficult terrain has reduced labor and equipment operating efficiencies. The time frame extension resulted in longer and escalating fixed costs, combined with additional anticipated volumes of stockpile material to be moved. In 2022, estimated costs associated with West Wanagon slope stabilization remediation and reclamation activities increased primarily as a result of increased material needed for stockpile stabilization and increased costs for equipment, operations and maintenance, increased manpower/headcount allocation and contractor/consultant cost impacts. As a result of these changes, ARO adjustments of $131 million were recorded in 2022 (of which $116 million related to the depleted Grasberg open pit and charged to production and delivery costs) and $397 million in 2021 (of which $340 million related to the depleted Grasberg open pit and charged to production and delivery costs). At December 31, 2022, FCX had accrued reclamation and closure costs of $1.1 billion for its PT-FI operations.

Indonesia government regulations issued in 2010 require a company to provide a mine closure guarantee in the form of a time deposit placed in a state-owned bank in Indonesia. At December 31, 2022, PT-FI had restricted time deposits totaling $103 million for mine closure and reclamation guarantees.

*Oil and Gas Properties.* Substantially all of FM O&G's oil and gas leases require that, upon termination of economic production, the working interest owners plug and abandon non-producing wellbores, remove equipment and facilities from leased acreage, and restore land in accordance with applicable local, state and federal laws. Following several sales transactions, FM O&G's remaining operating areas primarily include offshore California and the Gulf of Mexico (GOM). As of December 31, 2022, FM O&G AROs cover approximately 110 wells and 105 platforms and other structures and it had accrued reclamation and closure costs of $328 million.

**Litigation.** In addition to the material pending legal proceedings discussed below and above under "Environmental," we are involved periodically in ordinary routine litigation incidental to our business, some of which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief. SEC regulations require us to disclose environmental proceedings involving a governmental authority if we reasonably believe that such proceedings may result in monetary sanctions above a stated threshold. Pursuant to the SEC regulations, we use a threshold of $1 million for purposes of determining whether disclosure of any such environmental proceedings is required. Management does not believe, based on currently available information, that the outcome of any current pending legal proceeding will have a material adverse effect on FCX's financial condition, although individual or cumulative outcomes could be material to FCX's operating results for a particular period, depending on the nature and magnitude of the outcome and the operating results for the period.

*Louisiana Parishes Coastal Erosion Cases.* Certain FCX affiliates were named as defendants, in 13 cases filed in Louisiana state courts by six south Louisiana parishes (Cameron, Jefferson, Plaquemines, St. Bernard, St. John the Baptist and Vermilion), alleging that certain oil and gas exploration and production operations and sulfur mining and production operations in coastal Louisiana contaminated and damaged coastal wetlands and caused significant land loss along the Louisiana coast. The state of Louisiana, through the Attorney General and separately through the Louisiana Department of Natural Resources, intervened in the litigation in support of the parishes' claims. Certain FCX affiliates were named as defendants in two of the five cases that had been set for trial, both originally filed on November 8, 2013: <u>Parish of Plaquemines v. ConocoPhillips Company et al.</u>, 25th Judicial District Court, Plaquemines Parish, Louisiana; No. 60-982, Div. B and <u>Parish of Plaquemines v. Hilcorp Energy Company et al.</u>, 25th Judicial District Court, Plaquemines Parish, Louisiana; No. 60-999, Div. B. In 2019, affiliates of FCX reached an agreement in principle to settle all 13 cases, and as of October 2022, all parties have executed the settlement agreement. The settlement agreement does not include any admission of liability by FCX or its affiliates. FCX recorded a charge in 2019 for the initial payment of $15 million, which FCX expects to pay in trust to later be deposited into a newly formed Coastal Zone Recovery Fund (the Fund) if the state of Louisiana passes enabling legislation to establish the Fund within three years of execution of the settlement agreement. Upon payment of the $15 million, the FCX affiliates will be fully released and dismissed from all 13 pending cases. The maximum out-of-pocket settlement payment will be $23.5 million, including the initial $15 million payment. The settlement agreement will also require the FCX affiliates to pay into the Fund twenty annual installments of $4.25 million beginning in 2023 provided the state of Louisiana passes the enabling legislation. The first two of those annual installments are conditioned only on the enactment of the enabling legislation within three years of execution of the settlement agreement, but all subsequent installments are also conditioned on the FCX affiliates receiving simultaneous reimbursement on a dollar-for-dollar basis from the proceeds of environmental credit sales generated by the Fund, resulting in the $23.5 million maximum total payment obligation.

*Asbestos and Talc Claims*. Since approximately 1990, various FCX affiliates have been named as defendants in a large number of lawsuits alleging personal injury from exposure to asbestos or talc allegedly contained in industrial products such as electrical wire and cable, raw materials such as paint and joint compounds, talc-based lubricants used in rubber manufacturing or from asbestos contained in buildings and facilities located at properties owned or operated by affiliates of FCX. Many of these suits involve a large number of codefendants. Based on litigation results to date and facts currently known, FCX believes there is a reasonable possibility that losses may have been incurred related to these matters; however, FCX also believes that the amounts of any such losses, individually or in the aggregate, are not material to its consolidated financial statements. There can be no assurance that future developments will not alter this conclusion.

There has been a significant increase in the number of cases alleging the presence of asbestos contamination in talc-based cosmetic and personal care products and in cases alleging exposure to talc products that are not alleged to be contaminated with asbestos. The primary targets have been the producers of those products, but defendants in many of these cases also include talc miners. Cyprus Amax Minerals Company (CAMC), an indirect wholly owned subsidiary of FCX, and Cyprus Mines Corporation (Cyprus Mines), a wholly owned subsidiary of CAMC, are among those targets. Cyprus Mines was engaged in talc mining and processing from 1964 until 1992 when it exited its talc business by conveying it to a third party in two related transactions. Those transactions involved (1) a transfer by Cyprus Mines of the assets of its talc business to a newly formed subsidiary that assumed all pre-sale and post-sale talc liabilities, subject to limited reservations, and (2) a sale of the stock of that subsidiary to the third party. In 2011, the third party sold that subsidiary to Imerys Talc America (Imerys), an affiliate of Imerys S.A. In accordance with the terms of the 1992 transactions and subsequent agreements, Imerys undertook the defense and indemnification of Cyprus Mines and CAMC in talc lawsuits.

Cyprus Mines has contractual indemnification rights, subject to limited reservations, against Imerys, which historically acknowledged those indemnification obligations and took responsibility for all cases tendered to it. However, in February 2019, Imerys filed for Chapter 11 bankruptcy protection, which triggered an immediate automatic stay under the federal bankruptcy code prohibiting any party from continuing or initiating litigation or asserting new claims against Imerys. As a result, Imerys stopped defending the talc lawsuits against Cyprus Mines and CAMC. In addition, Imerys took the position that it alone owns, and has the sole right to access, the proceeds of the legacy insurance coverage of Cyprus Mines and CAMC for talc liabilities. In March 2019, Cyprus Mines and CAMC challenged this position and obtained emergency relief from the bankruptcy court to gain access to the insurance until the question of ownership and contractual access could be decided in an adversary proceeding before the bankruptcy court, which is currently on hold.

In January 2021, Imerys filed the form of a settlement and release agreement to be entered into by CAMC, Cyprus Mines, FCX, Imerys and the other debtors, tort claimants' committee and future claims representative in the Imerys bankruptcy. In accordance with the global settlement, among other things, (1) CAMC will pay a total of $130 million in cash to a settlement trust in seven annual installments, which will be guaranteed by FCX, and (2) CAMC and Cyprus Mines and their affiliates will contribute to the settlement trust all rights that they have to the proceeds of certain legacy insurance policies as well as indemnity rights they have against Johnson & Johnson, and Imerys also obtained an injunction temporarily staying approximately 950 talc lawsuits against CAMC and Cyprus Mines, which has been extended through July 2023. The interim stay is a component of the global settlement but there can be no assurance that the bankruptcy court will continue to impose the interim stay.

As part of the global settlement, Cyprus Mines filed for Chapter 11 bankruptcy protection in February 2021. In connection with executing the settlement and release agreement, FCX concluded that it has a probable loss and, in 2020, recorded a $130 million charge to environmental obligations and shutdown costs.

Mediation to resolve open issues in the Imerys and Cyprus Mines bankruptcy cases, including the adequacy of the global settlement, is ongoing, and FCX expects it to continue at least through first-quarter 2023.

FCX's global settlement is subject to, among other things, votes by claimants in both the Imerys and Cyprus Mines bankruptcy cases as well as bankruptcy court approvals in both cases, and there can be no assurance that the global settlement will be successfully implemented. FCX has a $130 million liability balance at December 31, 2022, associated with the proposed settlement.

**Tax and Other Matters.** FCX's operations are in multiple jurisdictions where uncertainties arise in the application of complex tax regulations. Some of these tax regimes are defined by contractual agreements with the local government, while others are defined by general tax laws and regulations. FCX and its subsidiaries are subject to

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

reviews of its income tax filings and other tax payments, and disputes can arise with the taxing authorities over the interpretation of its contracts or laws. The final taxes paid may be dependent upon many factors, including negotiations with taxing authorities. In certain jurisdictions, FCX pays a portion of the disputed amount before formally appealing an assessment. Such payment is recorded as a receivable if FCX believes the amount is collectible.

*Cerro Verde Royalty Dispute.* SUNAT (National Superintendency of Customs and Administration) assessed mining royalties on ore processed by the Cerro Verde concentrator for the period from December 2006 to December 2013. No royalty assessments were issued for the years after 2013, as Cerro Verde began paying royalties on all of its production in January 2014 under its new 15-year stability agreement. Cerro Verde contested each of these assessments because it believes that its 1998 stability agreement exempts from royalties all minerals extracted from its mining concession, irrespective of the method used for processing such minerals. During 2021, Cerro Verde paid the balance of its royalty dispute liabilities and has no remaining exposure associated with the royalty dispute with the Peruvian tax authorities.

On February 28, 2020, FCX filed on its own behalf and on behalf of Cerro Verde international arbitration proceedings against the Peruvian government under the United States-Peru Trade Promotion Agreement. The hearing on the merits is scheduled to take place in May 2023. In April 2020, SMM Cerro Verde Netherlands B.V. (SMM Cerro Verde), another shareholder of Cerro Verde, filed parallel international arbitration proceedings against the Peruvian government under the Netherlands-Peru Bilateral Investment Treaty. SMM Cerro Verde's hearing on the merits took place in February 2023. No amounts have been recorded for potential gain contingencies associated with the international arbitration proceedings.

&nbsp;&nbsp;&nbsp;&nbsp;

*Other Peru Tax Matters.* Cerro Verde has also received assessments from SUNAT for additional taxes, penalties and interest related to various audit exceptions for income and other taxes. Cerro Verde has filed or will file objections to the assessments because it believes it has properly determined and paid its taxes. A summary of these assessments follows:

---

| | | | |
|:---|:---|:---|:---|
| Tax Year | Tax Assessment | Penalties and Interest | Total |
| 2003 to 2008 | $48 | $130 | $178 |
| 2009 | 56 | 52 | 108 |
| 2010 | 54 | 125 | 179 |
| 2011 and 2012 | 42 | 73 | 115 |
| 2013 | 48 | 66 | 114 |
| 2014 to 2017 | 73 | 30 | 103 |
|  | $321 | $476 | $797 |

---

As of December 31, 2022, Cerro Verde had paid $741 million on these disputed tax assessments. A reserve has been applied against these payments totaling $408 million, resulting in a net receivable of $333 million (included in other assets), which Cerro Verde believes is collectible.

Cerro Verde's income tax assessments, penalties and interest included in the table above totaled $0.7 billion at December 31, 2022, of which $0.4 billion has not been charged to expense.

*Indonesia Tax Matters.* PT-FI has received assessments from the Indonesia tax authorities for additional taxes and interest related to various audit exceptions for income and other taxes. PT-FI has filed objections to the assessments because it believes it has properly determined and paid its taxes. Excluding surface water tax assessments discussed below and the Indonesia government's previous imposition of a 7.5% export duty that PT-FI paid under protest during the period April 2017 to December 21, 2018 (refer to Note 13), a summary of these assessments, including potential penalties follows:

---

| | | | |
|:---|:---|:---|:---|
| Tax Year | Tax Assessment | Penalties and Interest | Total |
| 2005 | $62 | $29 | $91 |
| 2007 | 45 | 22 | 67 |
| 2012 and 2013 | 41 | 41 | 82 |
| 2014 and 2015 | 108 |  | 108 |
| 2016 | 257 | 336 | 593 |
| 2017 | 7 | 2 | 9 |
|  | $520 | $430 | $950 |

---

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

As of December 31, 2022, PT-FI had paid $193 million on these disputed tax assessments. A reserve has been applied against these payments totaling $181 million, resulting in a net receivable of $12 million (included in other assets), which PT-FI believes is collectible.

PT-FI's income tax assessments, penalties and interest included in the table above totaled $0.9 billion at December 31, 2022, of which $0.4 billion has not been charged to expense.

*Surface Water Taxes*. PT-FI received assessments from the local regional tax authority in Central Papua, Indonesia, for additional taxes and penalties related to surface water taxes for the period from January 2011 through December 2018. As a result, PT-FI offered to pay one trillion rupiah to settle these historical surface water tax disputes and charged $69 million to production and delivery costs in 2018. In 2019, PT-FI agreed to a final settlement of 1.394 trillion rupiah (approximately $99 million) and recorded an incremental charge of $28 million. PT-FI paid 708.5 billion rupiah ($50 million) in October 2019, and paid the balance of 685.5 billion rupiah ($48 million) during 2021.

*Withholding Tax Assessments*. In January 2019, the Indonesia Supreme Court rendered an unfavorable decision related to a PT-FI 2005 withholding tax matter. PT-FI had also received an unfavorable Indonesia Supreme Court decision in November 2017. PT-FI currently has other pending cases at the Indonesia Supreme Court related to withholding taxes for employees and other service providers for the year 2005 and the year 2007, which total $42 million (based on the exchange rate as of December 31, 2022, and included in accounts payable and accrued liabilities in the consolidated balance sheet at December 31, 2022), including penalties and interest.

*Smelter Development Progress*. In January 2021, the Indonesia government levied an administrative fine of $149 million for the period from March 30, 2020, through September 30, 2020, on PT-FI for failing to achieve physical development progress on its greenfield smelter as of July 31, 2020. On January 13, 2021, PT-FI responded to the Indonesia government objecting to the fine because of events outside of its control causing a delay of the greenfield smelter's development progress. PT-FI believes that its communications during 2020 with the Indonesia government were not properly considered before the administrative fine was levied.

In June 2021, the Indonesia government issued a ministerial decree for the calculation of an administrative fine for lack of smelter development in light of the COVID-19 pandemic, and in 2021, PT-FI recorded charges totaling $16 million for a potential settlement of the administrative fine. In January 2022, the Indonesia government submitted a new estimate of the administrative fine totaling $57 million, and in March 2022, PT-FI paid the administrative fine and recorded an additional charge of $41 million. Based on PT-FI's revised smelter construction schedule, PT-FI does not believe any additional fines should be applied and will dispute any attempts by the Indonesia government to levy additional fines, which could be significant.

*PT-FI and PT Smelting Export Licenses*. Indonesia regulations require PT-FI and PT Smelting to renew their export licenses annually (PT-FI's export license for copper concentrate is subject to review by the Indonesia government every six months, depending on greenfield smelter construction progress). PT-FI's current export license is scheduled for renewal in March 2023, and PT-FI is preparing its renewal application. PT Smelting's current anodes slimes export license expires in November 2023.

While PT-FI's special mining license (IUPK) provides that exports continue through 2023 (subject to force majeure considerations), recent press reports have indicated that the Indonesia government is considering a ban of copper concentrate exports effective in June 2023 under regulations that were issued in 2020 and 2021. In addition, PT Smelting exports may also be restricted (contrary to the expiration date of PT Smelting's current export license noted above). PT-FI plans to work cooperatively with the Indonesia government to continue exports as required until the smelter is fully commissioned.

**Letters of Credit, Bank Guarantees and Surety Bonds.** Letters of credit and bank guarantees totaled $312 million at December 31, 2022, primarily associated with environmental obligations, AROs and for copper concentrate shipments from PT-FI to Atlantic Copper as required by Indonesia regulations. In addition, FCX had surety bonds totaling $488 million at December 31, 2022, primarily associated with environmental obligations and AROs.

**Insurance.** FCX purchases a variety of insurance products to mitigate potential losses, which typically have specified deductible amounts or self-insured retentions and policy limits. FCX generally is self-insured for U.S. workers' compensation, but purchases excess insurance up to statutory limits. An actuarial analysis is performed twice a year on the various casualty insurance programs covering FCX's U.S.-based mining operations, including

------

workers' compensation, to estimate expected losses. At December 31, 2022, FCX's liability for expected losses under these insurance programs totaled $62 million, which consisted of a current portion of $10 million (included in accounts payable and accrued liabilities) and a long-term portion of $52 million (included in other liabilities). In addition, FCX has receivables of $23 million (a current portion of $5 million included in other accounts receivable and a long-term portion of $18 million included in other assets) for expected claims associated with these losses to be filed with insurance carriers.

FCX's oil and gas operations are subject to all of the risks normally incidental to the production of oil and gas, including well blowouts, cratering, explosions, oil spills, releases of gas or well fluids, fires, pollution and releases of toxic gas, each of which could result in damage to or destruction of oil and gas wells, production facilities or other property, or injury to persons. While FCX is not fully insured against all risks related to its oil and gas operations, its insurance policies provide limited coverage for losses or liabilities relating to pollution, with broader coverage for sudden and accidental occurrences. FCX is self-insured for named windstorms in the GOM.

**Contractual Obligations.** At December 31, 2022, based on applicable prices on that date, FCX has unconditional purchase obligations (including take-or-pay contracts with terms less than one year) of $4.8 billion, primarily comprising the procurement of copper concentrate ($3.6 billion), transportation services ($0.5 billion) and electricity ($0.3 billion). Some of FCX's unconditional purchase obligations are settled based on the prevailing market rate for the service or commodity purchased. In some cases, the amount of the actual obligation may change over time because of market conditions. Obligations for copper concentrate provide for deliveries of specified volumes to Atlantic Copper at market-based prices. Transportation obligations are primarily for South America contracted ocean freight. Electricity obligations are primarily for long-term power purchase agreements in North America and contractual minimum demand at the South America mines.

FCX's unconditional purchase obligations total $1.6 billion in 2023, $1.5 billion in 2024, $1.0 billion in 2025, $0.3 billion in 2026, $0.1 billion in 2027 and $0.3 billion thereafter. During the three-year period ended December 31, 2022, FCX fulfilled its minimum contractual purchase obligations.

**IUPK - Indonesia.** In December 2018, FCX completed the 2018 Transaction with the Indonesia government regarding PT-FI's long-term mining rights and share ownership. Concurrent with the closing of the 2018 Transaction, the Indonesia government granted PT-FI an IUPK to replace its former Contract of Work, enabling PT-FI to conduct operations in the Grasberg minerals district through 2041. Under the terms of the IUPK, PT-FI was granted an extension of mining rights through 2031, with rights to extend mining rights through 2041, subject to PT-FI completing the development of additional smelting capacity in Indonesia by the end of 2023 (an extension of which has been requested as a result of COVID-19 mitigation measures, subject to the approval of the Indonesia government, refer to Note 12), and fulfilling its defined fiscal obligations to the Indonesia government. The IUPK, and related documentation, contains legal and fiscal terms and is legally enforceable through 2041, assuming the additional extension is received. In addition, FCX, as a foreign investor, has rights to resolve investment disputes with the Indonesia government through international arbitration.

The key fiscal terms set forth in the IUPK include a 25% corporate income tax rate, a 10% profits tax on net income, and royalty rates of 4% for copper, 3.75% for gold and 3.25% for silver. PT-FI's royalties charged against revenues totaled $357 million in 2022, $319 million in 2021 and $160 million in 2020.

Dividend distributions from PT-FI to FCX totaled $2.5 billion in 2022 and $1.0 billion in 2021 and are subject to a 10% withholding tax. There were no dividend distributions from PT-FI to FCX in 2020.

The IUPK requires PT-FI to pay export duties of 5%, declining to 2.5% when smelter development progress exceeds 30% and eliminated when development progress for additional smelting capacity in Indonesia exceeds 50%. In December 2022, PT-FI received approval, based on construction progress achieved, for a reduction in export duties from 5% to 2.5%, which was effective immediately. At December 31, 2022, construction of the greenfield smelter was approximately 50% complete. PT-FI's export duties totaled $325 million in 2022, $218 million in 2021 and $92 million in 2020. Upon receiving verification and approval from the Indonesia government that construction progress has exceeded 50%, PT-FI expects export duties may be eliminated.

Beginning in 2019, the IUPK also requires PT-FI to pay surface water taxes of $15 million annually, which are recognized in production and delivery costs.

In connection with a memorandum of understanding previously entered into with the Indonesia government in July 2014, PT-FI provided an assurance bond to support its commitment to construct a greenfield smelter in Indonesia ($133 million based on exchange rate as of December 31, 2022).

<u>Chiyoda Contract</u>. In July 2021, PT-FI awarded a construction contract to Chiyoda for the construction of a greenfield smelter in Gresik, Indonesia with an estimated contract cost of $2.8 billion. The smelter is expected to be commissioned during 2024.

**Indemnification.** The PT-FI divestment agreement, discussed in Note 3, provides that FCX will indemnify MIND ID and PTI from any losses (reduced by receipts) arising from any tax disputes of PT-FI disclosed to MIND ID in a Jakarta, Indonesia tax court letter limited to PTI's respective percentage share at the time the loss is finally incurred. Any net obligations arising from any tax settlement would be paid on December 21, 2025. FCX had accrued $74 million as of December 31, 2022, and $78 million as of December 31, 2021, (included in other liabilities in the consolidated balance sheets) related to this indemnification.

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

**Community Development Programs.** FCX has adopted policies that govern its working and engagement relationships with the communities where it operates. These policies are designed to guide FCX's practices and programs in a manner that respects and promotes basic human rights and the culture of the local people impacted by FCX's operations. FCX continues to make significant expenditures on community development, education, health, training, and cultural programs.

PT-FI provides funding and technical assistance to support various community development programs in areas such as health, education, economic development and local infrastructure. In 1996, PT-FI established a social investment fund with the aim of contributing to social and economic development in the Mimika Regency. Prior to 2019, the fund was mainly managed by the Amungme and Kamoro Community Development Organization, a community-led institution. In 2019, a new foundation, the Amungme and Kamoro Community Empowerment Foundation (Yayasan Pemberdayaan Masyarakat Amungme dan Kamoro, or YPMAK) was established, and in 2020, PT-FI appointed YPMAK to assist in distributing a significant portion of PT-FI's funding to support the development and empowerment of the local indigenous Papuan people. YPMAK is governed by a Board of Governors consisting of seven representatives, including four from PT-FI.

In addition, since 2001, PT-FI has voluntarily established and contributed to land rights trust funds administered by Amungme and Kamoro representatives that focus on socioeconomic initiatives, human rights and environmental issues.

PT-FI is committed to the continued funding of YPMAK programs and the land rights trust funds, as well as for other local-community development initiatives through 2041 and has made and expects to continue making annual investments in public health, education and local economic development. PT-FI recorded charges totaling $123 million in 2022, $109 million in 2021 and $67 million in 2020 to cost of sales for social and economic development programs.

**Guarantees.** FCX provides certain financial guarantees (including indirect guarantees of the indebtedness of others) and indemnities.

Prior to its acquisition by FCX, FMC and its subsidiaries have, as part of merger, acquisition, divestiture and other transactions, from time to time, indemnified certain sellers, buyers or other parties related to the transaction from and against certain liabilities associated with conditions in existence (or claims associated with actions taken) prior to the closing date of the transaction. As part of these transactions, FMC indemnified the counterparty from and against certain excluded or retained liabilities existing at the time of sale that would otherwise have been transferred to the party at closing. These indemnity provisions generally now require FCX to indemnify the party against certain liabilities that may arise in the future from the pre-closing activities of FMC for assets sold or purchased. The indemnity classifications include environmental, tax and certain operating liabilities, claims or litigation existing at closing and various excluded liabilities or obligations. Most of these indemnity obligations arise from transactions that closed many years ago, and given the nature of these indemnity obligations, it is not possible to estimate the maximum potential exposure. Except as described in the following sentence, FCX does not consider any of such obligations as having a probable likelihood of payment that is reasonably estimable, and accordingly, has not recorded any obligations associated with these indemnities. With respect to FCX's environmental indemnity obligations, any expected costs from these guarantees are accrued when potential environmental obligations are considered by management to be probable and the costs can be reasonably estimated.

**NOTE 14. FINANCIAL INSTRUMENTS**

FCX does not purchase, hold or sell derivative financial instruments unless there is an existing asset or obligation, or it anticipates a future activity that is likely to occur and will result in exposure to market risks, which FCX intends to offset or mitigate. FCX does not enter into any derivative financial instruments for speculative purposes, but has entered into derivative financial instruments in limited instances to achieve specific objectives. These objectives principally relate to managing risks associated with commodity price changes, foreign currency exchange rates and interest rates.

**Commodity Contracts.** From time to time, FCX has entered into derivative contracts to hedge the market risk associated with fluctuations in the prices of commodities it purchases and sells. Derivative financial instruments used by FCX to manage its risks do not contain credit risk-related contingent provisions.

In April 2020, FCX entered into forward sales contracts for 150 million pounds of copper for settlement in May and June of 2020. The forward sales provided for fixed pricing of $2.34 per pound of copper on approximately 60% of North America's sales volumes for May and June 2020. These contracts resulted in hedging losses totaling $24 million for the year ended December 31, 2020. There were no remaining forward sales contracts after June 30, 2020.

A discussion of FCX's other derivative contracts and programs follows.

<u>Derivatives Designated as Hedging Instruments - Fair Value Hedges</u>

*Copper Futures and Swap Contracts.* Some of FCX's U.S. copper rod and cathode customers request a fixed market price instead of the COMEX average copper price in the month of shipment. FCX hedges this price exposure in a manner that allows it to receive the COMEX average price in the month of shipment while the customers pay the fixed price they requested. FCX accomplishes this by entering into copper futures or swap contracts. Hedging gains or losses from these copper futures and swap contracts are recorded in revenues. FCX did not have any significant gains or losses resulting from hedge ineffectiveness during the years ended December 31, 2022, 2021 and 2020. At December 31, 2022, FCX held copper futures and swap contracts that qualified for hedge accounting for 82 million pounds at an average contract price of $3.80 per pound, with maturities through May 2024.

A summary of (losses) gains recognized in revenues for derivative financial instruments related to commodity contracts that are designated and qualify as fair value hedge transactions, including on the related hedged item for the years ended December 31 follows (in millions):

<u>Derivatives Not Designated as Hedging Instruments</u>

*Embedded Derivatives.* Certain FCX concentrate, copper cathode and gold sales contracts provide for provisional pricing primarily based on the LME copper price or the COMEX copper price and the London gold price at the time of shipment as specified in the contract. FCX receives market prices based on prices in the specified future month, which results in price fluctuations recorded in revenues until the date of settlement. FCX records revenues and invoices customers at the time of shipment based on then-current LME or COMEX copper prices and the London gold prices as specified in the contracts, which results in an embedded derivative (*i.e.*, a pricing mechanism that is finalized after the time of delivery) that is required to be bifurcated from the host contract. The host contract is the sale of the metals contained in the concentrate or cathode at the then-current LME or COMEX copper price and the London gold price. FCX applies the normal purchases and normal sales scope exception in accordance with derivatives and hedge accounting guidance to the host contract in its concentrate or cathode sales agreements since these contracts do not allow for net settlement and always result in physical delivery. The embedded derivative does not qualify for hedge accounting and is adjusted to fair value through earnings each period, using the period-end LME or COMEX copper forward prices and the adjusted London gold price, until the date of final pricing. Similarly, FCX purchases copper under contracts that provide for provisional pricing. Mark-to-market price

*Copper Forward Contracts.* Atlantic Copper, FCX's wholly owned smelting and refining unit in Spain, enters into copper forward contracts designed to hedge its copper price risk whenever its physical purchases and sales pricing periods do not match. These economic hedge transactions are intended to hedge against changes in copper prices, with the mark-to-market hedging gains or losses recorded in production and delivery costs. At December 31, 2022, Atlantic Copper held net copper forward purchase contracts for 6 million pounds at an average contract price of $3.82 per pound, with maturities through February 2023.

FCX's commodity contracts have netting arrangements with counterparties with which the right of offset exists, and it is FCX's policy to generally offset balances by contract on its balance sheet. FCX's embedded derivatives on provisional sales/purchase contracts are netted with the corresponding outstanding receivable/payable balances.

**Credit Risk.** FCX is exposed to credit loss when financial institutions with which it has entered into derivative transactions (commodity, foreign exchange and interest rate swaps) are unable to pay. To minimize the risk of such losses, FCX uses counterparties that meet certain credit requirements and periodically reviews the creditworthiness of these counterparties. As of December 31, 2022, the maximum amount of credit exposure associated with derivative transactions was $170 million.

**Other Financial Instruments.** Other financial instruments include cash, cash equivalents, restricted cash and cash equivalents, accounts receivable, investment securities, legally restricted trust assets, accounts payable and accrued liabilities, accrued income taxes, dividends payable and debt. The carrying value for these financial instruments classified as current assets or liabilities approximates fair value because of their short-term nature and generally negligible credit losses (refer to Note 15 for the fair values of investment securities, legally restricted funds and debt).

In addition, as of December 31, 2022, FCX has contingent consideration assets related to the sales of certain oil and gas properties (refer to Note 15 for the related fair values).

**Trade Accounts Receivable Agreements.** In 2021, PT-FI entered into agreements to sell certain trade accounts receivables to unrelated third-party financial institutions. The agreements were entered into in the normal course of business to fund the working capital for the additional quantity of copper to be supplied by PT-FI to PT Smelting. The balances sold under the agreements were excluded from trade accounts receivable on the consolidated balance sheets at December 31, 2022 and 2021. Receivables are considered sold when (i) they are transferred beyond the reach of PT-FI and its creditors, (ii) the purchaser has the right to pledge or exchange the receivables, and (iii) PT-FI has no continuing involvement in the transferred receivables. In addition, PT-FI provides no other forms of continued financial support to the purchaser of the receivables once the receivables are sold.

Gross amounts sold under these arrangements totaled $444 million in 2022 and $431 million in 2021. Discounts on the sold receivables totaled $4 million in 2022 and $2 million in 2021. As a result of the new tolling arrangements discussed in Note 3, no additional receivables will be sold under these agreements beginning in 2023.

**NOTE 15. FAIR VALUE MEASUREMENT**

Fair value accounting guidance includes a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). FCX did not have any significant transfers in or out of Level 3 for 2022.

FCX's financial instruments are recorded on the consolidated balance sheets at fair value except for contingent consideration associated with the sale of the Deepwater GOM oil and gas properties (which was recorded under the loss recovery approach) and debt. A summary of the carrying amount and fair value of FCX's financial instruments (including those measured at NAV as a practical expedient), other than cash and cash equivalents, restricted cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, accrued income taxes and dividends payable (refer to Note 14) follows:

a.Current portion included in other current assets and long-term portion included in other assets.

b.Excludes time deposits (which approximated fair value) included in (i) other current assets of $118 million at December 31, 2022, and $114 million at December 31, 2021, and (ii) other assets of $133 million at December 31, 2022, and $132 million at December 31, 2021, primarily associated with an assurance bond to support PT-FI's commitment for the development of a greenfield smelter in Indonesia (refer to Note 13 for further discussion) and PT-FI's closure and reclamation guarantees (refer to Note 12 for further discussion).

c.Refer to Note 14 for further discussion and balance sheet classifications.

d.Recorded at cost except for debt assumed in acquisitions, which are recorded at fair value at the respective acquisition dates.

**Valuation Techniques.** The U.S. core fixed income fund is valued at NAV. The fund strategy seeks total return consisting of income and capital appreciation primarily by investing in a broad range of investment-grade debt securities, including U.S. government obligations, corporate bonds, mortgage-backed securities, asset-backed securities and money market instruments. There are no restrictions on redemptions (which are usually within one business day of notice).

Equity securities are valued at the closing price reported on the active market on which the individual securities are traded and, as such, are classified within Level 1 of the fair value hierarchy.

Fixed income securities (government mortgage-backed securities, government securities, corporate bonds, asset-backed securities, collateralized mortgage-backed securities and municipal bonds) are valued using a bid-evaluation price or a mid-evaluation price. These evaluations are based on quoted prices, if available, or models that use observable inputs and, as such, are classified within Level 2 of the fair value hierarchy.

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

Money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets.

FCX's embedded derivatives on provisional copper concentrate, copper cathode and gold purchases and sales are valued using only quoted monthly LME or COMEX copper forward prices and the adjusted London gold prices at each reporting date based on the month of maturity (refer to Note 14 for further discussion); however, FCX's contracts themselves are not traded on an exchange. As a result, these derivatives are classified within Level 2 of the fair value hierarchy.

FCX's derivative financial instruments for copper futures and swap contracts and copper forward contracts that are traded on the respective exchanges are classified within Level 1 of the fair value hierarchy because they are valued using quoted monthly COMEX or LME prices at each reporting date based on the month of maturity (refer to Note 14 for further discussion). Certain of these contracts are traded on the over-the-counter market and are classified within Level 2 of the fair value hierarchy based on COMEX and LME forward prices.

In December 2016, FCX's sale of its Deepwater GOM oil and gas properties included up to $150 million in contingent consideration that was recorded at the total amount under the loss recovery approach. The contingent consideration is being received over time as future cash flows are realized from a third-party production handling agreement for an offshore platform, with the related payments commencing in third-quarter 2018. The contingent consideration included in (i) other current assets totaled $20 million at December 31, 2022 and 2021, and (ii) other assets totaled $47 million at December 31, 2022, and $70 million at December 31, 2021. The fair value of this contingent consideration was calculated based on a discounted cash flow model using inputs that include third-party estimates for reserves, production rates and production timing, and discount rates. Because significant inputs are not observable in the market, the contingent consideration is classified within Level 3 of the fair value hierarchy.

Long-term debt, including current portion, is primarily valued using available market quotes and, as such, is classified within Level 2 of the fair value hierarchy.

The techniques described above may produce a fair value that may not be indicative of NRV or reflective of future fair values. Furthermore, while FCX believes its valuation techniques are appropriate and consistent with other market participants, the use of different techniques or assumptions to determine fair value of certain financial instruments could result in a different fair value measurement at the reporting date. There have been no changes in the techniques used at December 31, 2022, as compared to those techniques used at December 31, 2021.

A summary of the changes in the fair value of FCX's Level 3 instrument, contingent consideration for the sale of the Deepwater GOM oil and gas properties, for the years ended December 31 follows:

---

| | | | |
|:---|:---|:---|:---|
| | 2022 | 2021 | 2020 |

**Major Customers and Affiliated Companies.** Copper concentrate sales to PT Smelting totaled 13% of FCX's consolidated revenues in 2022, 14% in 2021 and 12% in 2020, and they are the only customer that accounted for 10% or more of FCX's annual consolidated revenues during the three years ended December 31, 2022.

Consolidated revenues include sales to the noncontrolling interest owners of FCX's South America mining operations totaling $1.7 billion in 2022, $1.4 billion in 2021 and $0.9 billion in 2020, and PT-FI's sales to PT Smelting totaling $3.0 billion in 2022, $3.1 billion in 2021 and $1.8 billion in 2020.

**Labor Matters*.*** As of December 31, 2022, approximately 30% of FCX's global labor force was covered by collective bargaining agreements, and approximately 2% was covered by agreements that will or were scheduled to expire during 2023 or that had expired as of December 31, 2022, and continue to be negotiated. In February 2022, PT-FI completed negotiations with its unions on a two-year collective bargaining agreement that is effective through March 2024.

**Business Segments.** FCX has organized its mining operations into four primary divisions - North America copper mines, South America mining, Indonesia mining and Molybdenum mines, and operating segments that meet certain thresholds are reportable segments. Separately disclosed in the following tables are FCX's reportable segments, which include the Morenci, Cerro Verde and Grasberg (Indonesia Mining) copper mines, the Rod & Refining operations and Atlantic Copper Smelting & Refining.

Intersegment sales between FCX's business segments are based on terms similar to arms-length transactions with third parties at the time of the sale. Intersegment sales may not be reflective of the actual prices ultimately realized because of a variety of factors, including additional processing, timing of sales to unaffiliated customers and transportation premiums.

FCX defers recognizing profits on sales from its mines to other segments, including Atlantic Copper Smelting & Refining and on 39.5% of PT-FI's sales to PT Smelting (25.0% prior to April 30, 2021) until final sales to third parties occur. Quarterly variations in ore grades, the timing of intercompany shipments and changes in product prices result in variability in FCX's net deferred profits and quarterly earnings.

Beginning in 2023, PT-FI's commercial arrangement with PT Smelting converted to a tolling arrangement. Under this arrangement, PT-FI pays PT Smelting a tolling fee to smelt and refine its concentrate and will retain title to all products for sale to third parties (*i.e.,* there are no further sales from PT-FI to PT Smelting).

FCX allocates certain operating costs, expenses and capital expenditures to its operating divisions and individual segments. However, not all costs and expenses applicable to an operation are allocated. U.S. federal and state income taxes are recorded and managed at the corporate level (included in Corporate, Other & Eliminations), whereas foreign income taxes are recorded and managed at the applicable country level. In addition, most mining exploration and research activities are managed on a consolidated basis, and those costs, along with some selling, general and administrative costs, are not allocated to the operating divisions or individual segments. Accordingly, the following Financial Information by Business Segment reflects management determinations that may not be indicative of what the actual financial performance of each operating division or segment would be if it was an independent entity.

*North America Copper Mines.* FCX operates seven open-pit copper mines in North America - Morenci, Safford (including Lone Star), Bagdad, Sierrita and Miami in Arizona, and Chino and Tyrone in New Mexico. The North America copper mines include open-pit mining, sulfide-ore concentrating, leaching and SX/EW operations. A majority of the copper produced at the North America copper mines is cast into copper rod by FCX's Rod & Refining segment. In addition to copper, certain of FCX's North America copper mines also produce molybdenum concentrate, gold and silver.

The Morenci open-pit mine, located in southeastern Arizona, produces copper cathode and copper concentrate. In addition to copper, the Morenci mine also produces molybdenum concentrate. During 2022, the Morenci mine produced 43% of FCX's North America copper and 15% of FCX's consolidated copper production.

*South America Mining.* South America mining includes two operating copper mines - Cerro Verde in Peru and El Abra in Chile. These operations include open-pit mining, sulfide-ore concentrating, leaching and SX/EW operations.

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

The Cerro Verde open-pit copper mine, located near Arequipa, Peru, produces copper cathode and copper concentrate. In addition to copper, the Cerro Verde mine also produces molybdenum concentrate and silver. During 2022, the Cerro Verde mine produced 83% of FCX's South America copper and 23% of FCX's consolidated copper production.

*Indonesia Mining.* Indonesia mining includes PT-FI's Grasberg minerals district that produces copper concentrate that contains significant quantities of gold and silver. During 2022, PT-FI's Grasberg minerals district produced 37% of FCX's consolidated copper production and 99% of FCX's consolidated gold production.

*Molybdenum Mines.* Molybdenum mines include the wholly owned Henderson underground mine and Climax open-pit mine, both in Colorado. The Henderson and Climax mines produce high-purity, chemical-grade molybdenum concentrate, which is typically further processed into value-added molybdenum chemical products.

*Rod & Refining.* The Rod & Refining segment consists of copper conversion facilities located in North America, and includes a refinery and two rod mills, which are combined in accordance with segment reporting aggregation guidance. These operations process copper produced at FCX's North America copper mines and purchased copper into copper cathode and rod. At times these operations refine copper and produce copper rod for customers on a toll basis. Toll arrangements require the tolling customer to deliver appropriate copper-bearing material to FCX's facilities for processing into a product that is returned to the customer, who pays FCX for processing its material into the specified products.

*Atlantic Copper Smelting & Refining.* Atlantic Copper smelts and refines copper concentrate and markets refined copper and precious metals in slimes. During 2022, Atlantic Copper purchased 7% of its concentrate requirements from FCX's North America copper mines, 10% from FCX's South America mining operations and 18% from FCX's Indonesia mining operations, with the remainder purchased from unaffiliated third parties.

*Corporate, Other & Eliminations.* Corporate, Other & Eliminations consists of FCX's other mining, oil and gas operations and other corporate and elimination items, which include the Miami smelter, Freeport Cobalt (until its sale in September 2021), molybdenum conversion facilities in the U.S. and Europe, the greenfield smelter and PMR in Indonesia, certain non-operating copper mines in North America (Ajo, Bisbee and Tohono in Arizona) and other mining support entities.

**NOTE 17. SUPPLEMENTARY MINERAL RESERVE INFORMATION (UNAUDITED)**

Recoverable proven and probable mineral reserves as of December 31, 2022, have been prepared using industry accepted practice and conform to the disclosure requirements under Subpart 1300 of SEC Regulation S-K. FCX's proven and probable mineral reserves may not be comparable to similar information regarding mineral reserves disclosed in accordance with the guidance in other countries. Proven and probable mineral reserves were determined by the use of mapping, drilling, sampling, assaying and evaluation methods generally applied in the mining industry. Mineral reserves, as used in the reserve data presented here, mean an estimate of tonnage and grade of measured and indicated mineral resources that, in the opinion of the qualified person, can be the basis of an economically viable project. Proven mineral reserves are the economically mineable part of a measured mineral resource. To classify an estimate as a proven mineral reserve, the qualified person must possess a high degree of confidence of tonnage, grade and quality. Probable mineral reserves are the economically mineable part of an indicated or, in some cases, a measured mineral resource. The qualified person's level of confidence will be lower in determining a probable mineral reserve than it would be in determining a proven mineral reserve. To classify an estimate as a probable mineral reserve, the qualified person's confidence must still be sufficient to demonstrate that extraction is economically viable considering reasonable investment and market assumptions.

FCX's mineral reserve estimates are based on the latest available geological and geotechnical studies. FCX conducts ongoing studies of its ore bodies to optimize economic values and to manage risk. FCX revises its mine plans and estimates of proven and probable mineral reserves as required in accordance with the latest available studies.

Estimated recoverable proven and probable mineral reserves at December 31, 2022, were determined using metals price assumptions of $3.00 per pound for copper, $1,500 per ounce for gold and $12 per pound for molybdenum. For the three-year period ended December 31, 2022, LME copper settlement prices averaged $3.67 per pound, London PM gold prices averaged $1,789 per ounce and the weekly average price for molybdenum quoted by *Platts Metals Daily* averaged $14.44 per pound.

The recoverable proven and probable mineral reserves presented in the table below represent the estimated metal quantities from which FCX expects to be paid after application of estimated metallurgical recoveries and smelter recoveries, where applicable.

---

Note: Totals may not foot because of rounding.

a.Estimated consolidated recoverable copper reserves included 1.8 billion pounds in leach stockpiles and 0.3 billion pounds in mill stockpiles.

b.Estimated recoverable proven and probable mineral reserves from Indonesia reflect estimates of minerals that can be recovered through 2041. As a result, PT-FI's current long-term mine plan and planned operations are based on the assumption that PT-FI will abide by the terms and conditions of the IUPK and will be granted the 10-year extension from 2031 through 2041 (refer to Note 13 for discussion of PT-FI's IUPK). As a result, PT-FI will not mine all of these mineral reserves during the initial term of the IUPK. Prior to the end of 2031, PT-FI expects to mine 46% of its proven and probable recoverable mineral reserves at December 31, 2022, representing 49% of FCX's net equity share of recoverable copper reserves and 51% of FCX's net equity share of recoverable gold reserves.

c.Consolidated mineral reserves represent estimated metal quantities after reduction for joint venture partner interests at the Morenci mine in North America (refer to Note 3 for further discussion). Excluded from the table above were FCX's estimated recoverable proven and probable mineral reserves of 340 million ounces of silver, which were determined using $20 per ounce.

d.Net equity interest mineral reserves represent estimated consolidated metal quantities further reduced for noncontrolling interest ownership (refer to Note 3 for further discussion of FCX's ownership in subsidiaries). Excluded from the table above were FCX's estimated recoverable proven and probable mineral reserves of 226 million ounces of silver.

**Item 16. Form 10-K Summary.**

Not applicable.

**GLOSSARY OF TERMS** 

Following is a glossary of selected terms used throughout this Annual Report on Form 10-K that are technical in nature:

*Adits.* A horizontal passage leading into a mine for the purposes of access or drainage.

*Alluvial aquifers.* A water-bearing deposit of loosely arranged gravel, sand or silt left behind by a river or other flowing water.

*Anode.* A positively charged metal sheet, usually lead, on which oxidation occurs. During the electro-refining process, anodes are impure copper sheets from the smelting process that require further processing to produce refined copper cathode.

*Azurite.* A bluish supergene copper mineral and ore found in the oxidized portions of copper deposits often associated with malachite.

*Bench.* The horizontal floor cuttings along which mining progresses in an open-pit mine. As the pit progresses to lower levels, safety benches are left in the walls to catch any falling rock.

*Blasthole stoping.* An underground mining method that extracts the ore zone in large vertical rooms. The ore is broken by blasting using large-diameter vertical drill holes.

*Block cave.* A general term used to describe an underground mining method where the extraction of ore depends largely on the action of gravity. By continuously removing a thin horizontal layer at the bottom mining level of the ore column, the vertical support of the ore column is removed and the ore then caves by gravity.

*Bornite.* A red-brown isometric mineral comprising copper, iron and sulfur.

*British thermal unit or Btu.* One British thermal unit is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

*Brochantite.* A greenish-black copper mineral occurring in the oxidation zone of copper sulfide deposits.

*Cathode.* Refined copper produced by electro-refining of impure copper or by electrowinning.

*Chalcocite.* A grayish copper sulfide mineral, usually found as a supergene in copper deposits formed from the re-deposition of copper minerals that were solubilized from the oxide portion of the deposit.

*Chalcopyrite.* A brass-yellow sulfide of mineral copper and iron.

*Chrysocolla.* A bluish-green to emerald-green oxide copper mineral that forms incrustations and thin seams in oxidized parts of copper-mineral veins; a source of copper and an ornamental stone.

*Cobalt.* A tough, lustrous, nickel-white or silvery-gray metallic element often associated with nickel and copper ores from which it is obtained as a by-product.

*Concentrate.* The resulting product from the concentrating process that is composed predominantly of copper sulfide or molybdenum sulfide minerals. Further processing might include smelting and electro-refining, or roasting.

*Concentrating.* The process by which ore is separated into metal concentrate through crushing, milling and flotation.

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

*Concentrator.* A process plant used to separate targeted minerals from gangue and produce a mineral concentrate that can be marketed or processed by additional downstream processes to produce salable metals or mineral products. Term is used interchangeably with Mill.

*Contained metal.* The amount of metal in a mineral sample before the reduction of amounts unable to be recovered during the metallurgical process.

*Covellite.* A metallic, indigo-blue supergene mineral found in copper deposits.

*Crushed-ore leach pad.* A slightly sloping pad upon which leach ores are placed in lifts for processing.

*Cutoff grade.* The minimum grade contained in the ore for processing. When percentages are below this grade, the material would be routed to an overburden stockpile or left unmined. When percentages are above grade, the material would be processed using concentrating or leaching methods.

*Disseminations.* A mineral deposit in which the desired minerals occur as scattered particles in the rock that has sufficient quantity to be considered an ore deposit.

*Electrolytic refining.* The purification of metals by electrolysis. A large piece of impure copper is used as the anode with a thin strip of pure copper as the cathode.

*Electrowinning.* A process that uses electricity to plate copper contained in an electrolyte solution into copper cathode.

*Flotation.* A concentrating process in which valuable minerals attach themselves to bubbles of an oily froth for separation as concentrate. The gangue material from the flotation process reports as a tailing product.

*Grade.* The relative quality or percentage of metal content.

*Indigenous Peoples.* Indigenous Peoples are distinct social and cultural groups that share collective ancestral ties to the lands and natural resources where they live, occupy or from which they have been displaced.

*Leach stockpiles.* A quantity of leachable ore placed on a leach pad or in another suitable location that permits leaching and collection of solutions that contain solubilized metal.

*Leaching.* The process of extracting copper using a chemical solution to dissolve copper contained in ore.

*Malachite.* A bright-green copper mineral (ore) that often occurs with azurite in oxidized zones of copper deposits.

*Metric ton.* The equivalent of 2,204.62 pounds.

*Mill stockpile.* Millable ore that has been mined, and is available for future processing.

*Mine-for-leach.* A mining operation focused on mining only leachable ores. Also, referred to as crushed leach.

*Mineralization.* The process by which a mineral is introduced into a rock, resulting in concentration of minerals that may form a valuable or potentially valuable deposit.

*Molybdenite.* A black, platy, disulfide of molybdenum. It is the most common ore of molybdenum.

*Ore body.* A continuous, well-defined mass of mineralized material of sufficient ore content to make extraction economically feasible.

*Oxide.* In mining, oxide is used as an ore classification relating to material that usually leaches well but does not perform well in a concentrator. Oxide minerals in mining refer to an oxidized form.

*Paste backfill.* A slurry of paste material produced from tailings with engineered cement and water content that is used to fill underground mined out stopes.

*Porphyry.* A deposit in which minerals of copper, molybdenum, gold or, less commonly, tungsten and tin are disseminated or occur in stock-work of small veinlets within a large mass of hydro-thermally altered igneous rock.

------

<u>[**Table of Contents**](#i404a2cad92d34deba102aad6f6a60266_7)</u>

The host rock is commonly an intrusive porphyry, but other rocks intruded by a porphyry can also be hosts for ore minerals.

*Production level.* With respect to underground mining, the elevation of the underground works that permit extraction/transport of the ore to a common point, shaft or plant.

*Pseudomalachite.* A dark-green monoclinic copper mineral.

*Roasting.* The heating of sulfide ores to oxidize sulfides to facilitate further processing.

*Run-of-Mine (ROM).* Leachable ore that is mined and directly placed on a leach pad without utilizing any further processes to reduce particle size prior to leaching.

*Skarn.* A Swedish mining term for silicate gangue of certain iron ore and sulfide deposits of Archaean age, particularly those that have replaced limestone and dolomite. Its meaning has been generally expanded to include lime-bearing silicates, of any geologic age, derived from nearly pure limestone and dolomite with the introduction of large amounts of silicon, aluminum, iron and magnesium.

*Smelting.* The process of melting and oxidizing concentrate to separate copper and precious metals from metallic and non-metallic impurities, including iron, silica, alumina and sulfur.

*Solution extraction.* A process that transfers copper from a copper-bearing ore to an organic solution, then to an electrolyte. The electrolyte is then pumped to a tankhouse where the copper is extracted, using electricity, into a copper cathode (refer to the term Electrowinning), together referred to as solution extraction/electrowinning (SX/EW).

*Stope.* An underground mining method that is usually applied to highly inclined or vertical veins. Ore is extracted by driving horizontally upon it in a series of workings, one immediately over the other. Each horizontal working is called a stope because when a number of them are in progress, each working face under attack assumes the shape of a flight of stairs.

*Sulfide.* A mineral compound containing sulfur and a metal. Copper sulfides can be concentrated or leached, depending on the mineral type.

*Tailings.* The crushed and ground material remaining after economically recoverable minerals have been extracted. In upstream design and construction, tailings are deposited on the upstream side of the starter embankment, with subsequent crest raises progressively shifting upstream of each previous raise, using deposited tailings as a foundation. In downstream design and construction, tailings are deposited on the upstream side of the starter embankment. Borrow fill or a portion of the tailings are placed on the downstream side of the starter embankment. Subsequent crest raises progressively shift downstream of each previous raise, such that the previous raise becomes the foundation of the subsequent raise. As a result, the toe and the crest of the embankment progressively shift downstream as the embankment is raised. In centerline design and construction, tailings are deposited on the upstream side of the starter embankment. Borrow fill or a portion of the tailings are placed on the crest of the starter embankment. Subsequent crest raises are constructed vertically along the centerline of the previous raise such that the previous raise becomes the foundation of the subsequent raise. As a result, the toe of the embankment shifts downstream but the crest stays along initial alignment as the embankment is raised.

*Tolling.* The process of converting customer-owned material into specified products, which is then returned to the customer.

*Working interest*. An interest in an oil and gas lease that gives the owner of the interest the right to drill for and produce oil and gas on the leased acreage and requires the owner to pay a share of the costs of drilling and production operations.

## Exhibit 95.1

 **Exhibit 95.1**

**Mine Safety and Health Administration (MSHA) Safety Data**

FCX's U.S. mining operations are subject to regulations issued by MSHA under the U.S. Federal Mine Safety and Health Act of 1977 (the Mine Act). MSHA inspects our U.S. mines on a regular basis and issues various citations and orders when it believes a violation has occurred under the Mine Act. Whenever MSHA issues a citation or order, it also generally proposes a civil penalty, or fine, related to the alleged violation. Citations or orders can be contested and appealed, and as part of that process, are often reduced in severity and amount, and are sometimes dismissed. The number of citations, orders and proposed assessments varies depending on the size and type (underground or surface) of the mine, among other factors.

The following disclosures have been provided pursuant to Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act.

<u>Mine Safety Data</u>. Following provides additional information about references used in the following table to describe the categories of violations, orders or citations issued by MSHA under the Mine Act:

• **Section 104 S&S Citations**: Citations issued by MSHA under Section 104(a) of the Mine Act for violations of health or safety standards that could significantly and substantially contribute to a serious injury if left unabated.

• **Section 104(b) Orders**: Orders issued under Section 104(b) of the Mine Act, which represent a failure to abate a citation under Section 104(a) within the period prescribed by MSHA. This results in an order of immediate withdrawal from the area of the mine affected by the condition until MSHA determines that the violation has been abated.

• **Section 104(d) Citations and Orders**: Citations and orders issued by MSHA under Section 104(d) of the Mine Act for unwarrantable failure to comply with mandatory health or safety standards. These types of violations could significantly and substantially contribute to a serious injury; however, the conditions do not cause imminent danger (refer to discussion of imminent danger orders below).

• **Section 110(b)(2) Violations**: Flagrant violations identified by MSHA under Section 110(b)(2) of the Mine Act. The term flagrant with respect to a violation is defined as "a reckless or repeated failure to make reasonable efforts to eliminate a known violation of a mandatory health or safety standard that substantially and proximately caused, or reasonably could have expected to cause, death or serious bodily injury."

• **Section 107(a) Orders**: Orders issued by MSHA under Section 107(a) of the Mine Act for situations in which MSHA determined an imminent danger existed. Orders issued under Section 107(a) of the Mine Act require the operator of the mine to cause all persons (except authorized persons) to be withdrawn from the mine until the imminent danger and the conditions that caused such imminent danger cease to exist.

------

The following table details the violations, citations and orders issued to us by MSHA during the year ended December 31, 2022:

The following provides additional information of the types of proceedings that may be brought before the Commission:

• **Contest Proceedings** - A contest proceeding may be filed by an operator to challenge the issuance of a citation or order issued by MSHA.

• **Civil Penalty Proceedings** - A civil penalty proceeding may be filed by an operator to challenge a civil penalty MSHA has proposed for a violation contained in a citation or order. FCX does not institute civil penalty proceedings based solely on the assessment amount of proposed penalties. Any initiated adjudications described in the table below address substantive matters of law and policy instituted on conditions that are alleged to be in violation of mandatory standards or the Mine Act.

• **Discrimination Proceedings** - Involves a miner's allegation that he or she has suffered adverse employment action because he or she engaged in an activity protected under the Mine Act, such as making a safety complaint. Also includes temporary reinstatement proceedings involving cases in which a miner has filed a complaint with MSHA stating that he or she has suffered discrimination and the miner has lost his or her position.

• **Compensation Proceedings** - A compensation proceeding may be filed by miners entitled to compensation when a mine is closed by certain closure orders issued by MSHA. The purpose of the proceeding is to determine the amount of compensation, if any, due to miners idled by the orders.

• **Temporary Relief -** Applications for temporary relief are applications filed under Section 105(b)(2) of the Mine Act for temporary relief from any modification or termination of any order.

• **Appeals -** An appeal may be filed by an operator to challenge judges decisions or orders to the Commission, including petitions for discretionary review and review by the Commission on its own motion.

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

# 1 EXECUTIVE SUMMARY

This Technical Report Summary (TRS) is prepared by Qualified Persons (QPs) for Freeport-McMoRan Inc. (FCX), a leading international mining company with headquarters located in Phoenix, Arizona, United States (U.S.). The purpose of this TRS is to report mineral reserve and mineral resource estimates at the Cerro Verde mine using estimation parameters as of December 31, 2022.

## 1.1 Property Description, Current Status, and Ownership

The Cerro Verde mine is an open-pit copper and molybdenum mining complex that has been in operation since 1976. It produces copper concentrate and cathode products, with silver in the concentrate. The Cerro Verde mine also produces a molybdenum concentrate. The mine is situated approximately 30 kilometers southwest of the city of Arequipa, capital of the Arequipa province and the second largest city in Peru.

The mine operates 365 days per year on a 24 hour per day schedule. Mining and ore processing operations are currently in production and the mine is considered a production stage property. The Cerro Verde mine encompasses the Cerro Verde (CV), Santa Rosa (SR), and Cerro Negro (CN) ore deposits.

The Cerro Verde mine is operated by FCX through a majority owned subsidiary, Sociedad Minera Cerro Verde S.A.A. (SMCV). FCX holds a 53.56 percent ownership interest in SMCV, with the remaining 46.44 percent held by SMM Cerro Verde Netherlands B.V. (SMM) (21 percent), Compañía de Minas Buenaventura S.A.A. (BV) (19.58 percent), and other stockholders whose Cerro Verde shares are publicly traded on the Lima Stock Exchange (5.86 percent).

As of December 31, 2022, the Cerro Verde mine encompasses approximately 178,000 acres of mining concessions/holdings, including 62,000 acres of surface rights and 14,600 acres granted through an easement from the Peru National Assets Office, plus 150 acres of owned property, and 1,151 acres of rights-of-way outside the mining concession area.

## 1.2 Geology and Mineralization

The Cerro Verde mining district comprises a copper-molybdenum porphyry cluster that includes a series of deposits (CV, SR, and CN), which are related to calc-alkaline intrusions (dacite monzonite porphyry) and quartz-tourmaline hydrothermal breccia bodies.

In general, these deposits are low grade and high tonnage, genetically related to igneous epizonal intrusions and characterized by multiple events from a parental magmatic chamber, which are distributed along the Incapuquio fault system corridor.

In the Cerro Verde mining district, mineralization is directly linked to multiple igneous intrusive events. The resulting hypogene mineralization is dominantly chalcopyrite with minor bornite. Retrograde events resulted in a slight increase in chalcopyrite and precipitation of molybdenite. Supergene processes formed a profile containing zones of leached capping, oxide copper mineralization, chalcocite enrichment, and a mixed chalcocite-hypogene transition zone. Mineralization spans approximately 5.6 kilometers in length trending northwest-southeast and 1.6 kilometers in width.

### 1.3 Mineral Reserve Estimate

Mineral reserves are summarized from the Life-of-Mine (LOM) plan, which is the compilation of the relevant modifying factors for establishing an operational, economically viable mine plan.

Mineral reserves have been evaluated considering the modifying factors for conversion of measured and indicated resource classes into proven and probable reserves. Inferred resources are considered to be waste in the LOM plan. The details of the relevant modifying factors included in the estimation of mineral reserves are discussed in Sections 10 through 21.

The LOM plan includes the planned production to be extracted from the in-situ mine designs and from previously extracted material, known as Work-In-Process (WIP) inventories. WIP includes material on crushed leach and Run of Mine (ROM) leach pads for processing, and in stockpiles set aside to be rehandled and processed at a future date. WIP is estimated as of December 31, 2022, from production of reported deliveries through mid-year and the expected production to the end of the year.

As a point of reference, the mineral reserve estimate reports the in-situ ore and WIP inventories from the LOM plan containing copper, molybdenum, and silver metal and reported as commercially recoverable metal.

Table 1.1 summarizes the mineral reserves reported on a 100 percent and pro rata property ownership basis. The mineral reserve estimate is based on commodity prices of $3.00 per pound for copper, $12 per pound for molybdenum, and $20 per ounce for silver.

Notes

a. Reported as of December 31, 2022, using metal prices of $3.00 per pound for copper, $12 per pound for molybdenum, and $20 per ounce for silver.

b. Amounts may not foot because of rounding.

c. Operational cutoff grade reported as equivalent copper (EqCu).

d. Process recoveries include all applicable processes such as concentration, smelting, transportation losses, etc.

e. The Cerro Verde mine is operated by FCX through a majority owned subsidiary, Sociedad Minera Cerro Verde S.A.A. (SMCV). FCX holds a 53.56 percent ownership interest in SMCV, with the remaining 46.44 percent held by SMM Cerro Verde Netherlands B.V. (SMM - 21 percent), Compañía de Minas Buenaventura S.A.A. (BV - 19.58 percent), and other stockholders whose shares are publicly traded on the Lima Stock Exchange (Public Shares - 5.86 percent).

The mineral reserve estimate has been prepared using industry accepted practice and conforms to the disclosure requirements of the U.S. Securities and Exchange Commission (SEC) under Subpart 1300 of Regulation S-K (S-K1300). Mineral reserve and mineral resource estimates are evaluated annually, providing the opportunity to reassess the assumed conditions. All the technical and economic issues likely to influence the prospect of economic extraction are anticipated to be resolved under the stated assumed conditions.

## 1.4 Mineral Resource Estimate

Mineral resources are evaluated using the application of technical and economic factors to a geologic resource block model and employing optimization algorithms to generate digital surfaces of mining limits, using specialized geologic and mine planning computer software. The resulting surfaces volumetrically identify material as potentially economical, using the assumed parameters. Mineral resources are the resultant contained metal inventories.

The mineral resource estimate is the inventory of material identified as having a reasonable likelihood for economic extraction inside the mineral resource economic mining limit, less the mineral reserve volume, as applicable. The modifying factors are applied to measured, indicated, and inferred resource classifications to evaluate

Notes

a. Reported as of December 31, 2022, using metal prices of $3.50 per pound for copper, $15 per pound for molybdenum, and $20 per ounce for silver. Mineral resources are exclusive of mineral reserves.
b. Amounts may not foot because of rounding.
c. Internal cutoff grade reported as equivalent copper (EqCu).
d. Estimated expected recoveries are consistent with those for mineral reserves but would require additional work to substantiate.
e. The Cerro Verde mine is operated by FCX through a partially owned subsidiary, Sociedad Minera Cerro Verde S.A.A. (SMCV). FCX holds a 53.56 percent ownership interest in SMCV, with the remaining 46.44 percent held by SMM Cerro Verde Netherlands B.V. (SMM - 21 percent), Compañía de Minas Buenaventura S.A.A. (BV - 19.58 percent) and other stockholders whose shares are publicly traded on the Lima Stock Exchange (Public Shares - 5.86 percent).

The mineral resource estimate has been prepared using industry accepted practice and conforms to the disclosure requirements of S-K1300. Mineral reserve and mineral resource estimates are evaluated annually, providing the opportunity to reassess the assumed conditions. Although all the technical and economic issues likely to influence the prospect of economic extraction of the estimated mineral resource are anticipated to be resolved under the stated assumed conditions, no assurance can be given that the estimated mineral resource will become proven and probable mineral reserves.

## 1.6 Permitting Requirements

In the QP's opinion, the Cerro Verde mine has adequate plans and programs in place, is in good standing with Peruvian environmental regulatory authorities, and no current conditions related to environmental compliance, permitting, and local engagement represent a material risk to continued operations. The Cerro Verde mine staff have a high level of understanding of the requirements of environmental compliance, permitting, and local stakeholders in order to facilitate the development of the mineral reserve and mineral resource estimates. The periodic inspections by governmental agencies, FCX corporate staff, third-party reviews, and regular reporting confirm this understanding.

Based on the LOM plan, additional permits will likely be necessary in the future for continued operation of the Cerro Verde mine, including modifications to the Environmental and Social Impact Studies (ESIS) and obtaining approval for modified leach pad configurations, increased tailings storage capacity, and corresponding water supply.

## 1.7 Conclusions and Recommendations

FCX and the QPs believe that the geologic interpretation and modeling of exploration data, economic analysis, mine design and sequencing, process scheduling, and operating and capital cost estimation have been developed using accepted industry practices and that the stated mineral reserves and mineral resources comply with SEC regulations. Periodic reviews by third-party consultants confirm these conclusions.

No recommendations for additional work are identified for the reported mineral reserves and mineral resources as of December 31, 2022.

![img-1.jpeg](img-1.jpeg)

### 3.4 Mineral Rights and Significant Permitting

In Peru, mining rights through claims and concessions are regulated by Peru's general mining law. The Peru general mining law and Cerro Verde's mining stability agreement grant the surface rights of mining concessions located on government land. Government land obtained after 1997 must be leased or purchased. Cerro Verde's major operations take place in the mining concession 'Cerro Verde N° 1, 2, y 3' and in the Cerro Verde processing facilities concession 'Cerro Verde Beneficiation Plant', hereinafter known as

as of December 31, 2022

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

the Beneficiation Plant. SMCV is the titleholder of the entire mining concession, all other concessions, and areas where the Cerro Verde operations are located. They are retained through the annual payments of rights for the concessions or the corresponding penalties for not exploiting them. Surface land is not owned, however Supreme Decree 017-1996-AG granted mining companies surface rights of those concessions already titled by the time this regulation was passed upon formal declaration before the Peruvian Ministry of Energy and Mines (MINEM). Cerro Verde's mining and main core concessions were declared and exempted from the farmland's privatization processes. The Beneficiation Plant's authorization includes the processing and recovery methods of ore entirely sourced from the mining concession.

SMCV operates the mine in the Cerro Verde Production Unit (CVPU) which comprises among others, the Cerro Verde mining concession, and the Beneficiation Plant. The Beneficiation Plant has an authorization from MINEM to treat a total of 548,500 metric tons of ore per day of installed capacity through all processes.

SMCV has valid titles for the areas occupied by ancillary facilities such as the pump stations next to the Río Chili watershed in Uchumayo and the acid storage facilities in the nearby town of Matarani. It also owns the areas where the current 220 kilovolt (kV) line towers are located, and easements have been acquired for the electrical lines and for the water pipelines. Alternative routes for power lines, water lines, and storage facilities are also available.

SMCV signed a Contract of Investment Promotion Measures and Guarantees on July 17, 2012, under the general mining law, so the tax and administrative regime of that date applies to operations in the CVPU. The Stability Contract requires SMCV to pay an applicable income tax of 32 percent. In December 2015, SMCV submitted to the MINEM the Update of the Feasibility Study and Investment Schedule for the execution of the CVPU Expansion (CVPUE). After it was approved, SMCV signed an Addendum to the Stability Contract, including the updated Feasibility Study, in December 2016 and the initial execution of the CVPUE was completed. The term of this Stability Contract is 15 years from January 1, 2014, expiring on December 31, 2028.

With the CVPUE, SMCV, the Regional Government of Arequipa, provincial and district mayors, the National Water Authority, the representatives of the User Boards, and the civil society of Arequipa and the Water and Sewage Service Company of Arequipa (SEDAPAR) agreed on general guidelines for SMCV to finance and build the Wastewater Treatment Plant (WWTP) 'La Enlozada' and reuse part of the wastewater treated in this facility. This contract allows SMCV to reuse a cubic meter per second of treated wastewater on an annual average basis. The rest of the treated water that is within maximum permissible limits is available to the SEDAPAR authority to distribute. Between the WWTP and fresh water from the Río Chili, SMCV has licenses and authorization of 2,160 liters per second of average annual flow, as of December 31, 2022. SMCV has an additional water license of 200 liters per second from the CV and SR pit dewatering system.

### **3.5 Comment on Factors and Risks Affecting Access, Title, and Ability to Perform Work**

FCX and the Cerro Verde mine staff believe that all major permits and approvals are in place to support operations at the Cerro Verde mine. Based on the LOM plan, additional permits will likely be necessary in the future for increased capacities of leach pad stockpiles and TSFs as discussed in Section 17. Such processes to obtain these permits and the associated timelines are understood and similar permits have been granted in the

as of December 31, 2022

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

past. FCX and the Cerro Verde mine have environmental, land, water, and permitting departments that monitor and review all aspects of property ownership or other rights and permit requirements so that they are maintained in good standing and any issues are addressed in a timely manner.

The mine has a partially unionized workforce and has been subject to various lawsuits and work stoppages over the operating history of the mine. FCX and the Cerro Verde mine understand the importance of the workforce and work in good faith to resolve conflicts.

Political uncertainty has created potential instability in the regulatory environment in Peru. There have been widespread and sometimes violent political protests, including attacks on civil infrastructure and businesses, which have resulted in delays in the transport of supplies, products, and people at the Cerro Verde mine. Although the impact on mine supplies has been limited and the Cerro Verde mine continues to operate safely, the situation in Peru remains uncertain, and there is a risk that the protests could negatively impact operations. Any sustained impacts to operations would be incorporated into future mineral reserve and resource estimates.

As of December 31, 2022, FCX and the Cerro Verde mine believe the mine's access, payments for titles and rights to the mineral claims, and ability to perform work on the property are all in good standing. Further, to the extent known to the QPs, there are no significant encumbrances, factors, or risks that may affect the ability to perform work in support of the estimates of mineral reserves and mineral resources.

## **4 ACCESSIBILITY, CLIMATE, PHYSIOGRAPHY, LOCAL RESOURCES, AND INFRASTRUCTURE**

The property is located in the District of Uchumayo, Province of Arequipa, Department of Arequipa, in the southern part of Peru.

### **4.1 Accessibility**

The mine is accessible by two public highways: 30 kilometers by road south from Arequipa and 21 kilometers by road east from Route 108/AR 115. The mine is approximately 100 kilometers northeast of Matarani and 1,000 kilometers southeast of Lima. The Southern Railway of Peru connects Matarani to Arequipa and passes within 12 kilometers of the mine site. The nearest airport is in Arequipa, Peru.

### **4.2 Climate**

The property is situated in a mountainous desert environment with two markedly different seasons: rainy season (November to March) and dry season (April to October). The mine area is an arid desert with rainfall averaging about 40 millimeters per annum. Temperatures range from a low of freezing, with snowfall rare, to a high of approximately 25 degrees Celsius. The mine operates throughout the year with production marginally affected during the rainy season.

### **4.3 Physiography**

The regional topography is characterized by well-shaped rocky hills with gradual slopes at intermediate elevation. Mountain peaks reach elevations above 6,000 meters above sea level. Chachani, the highest snow-capped mountain in the area, is approximately 20

as of December 31, 2022

18

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

kilometers directly north of the city of Arequipa with an elevation of 6,057 meters. Chachani and Pichu Pichu are dormant volcanoes in the Arequipa region while El Misti, with an elevation of 5,822 meters located 15 kilometers northeast of Arequipa, is active and last erupted in 1985. A ridge of hills called the Coastal Batholith separates the Arequipa valley from the coastal prairie. The Coastal Batholith is part of the Occidental Branch foothills in the Andes Cordillera. The Río Chili, the main river in the region, flows through Arequipa west to the Pacific Ocean.

The area is seismically very active. The site is located within Earthquake Region 1, as designated in the Peruvian Code for Anti-seismic Design, or Zone 4 of the Uniform Building Code, 1997 edition.

The vegetation in the area is a mix of cacti, seasonal herbaceous vegetation, and some sparse shrubs species representing the local desert species, typical of a desert environment.

#### **4.4 Local Resources and Infrastructure**

Infrastructure is in place to support mining operations. Section 15 contains additional detail regarding site infrastructure.

Accommodations for mine employees and supplies are available in the nearby communities of Arequipa and Matarani.

Cerro Verde operations are supplied water by renewable sources through a series of storage reservoirs on the Río Chili watershed that collect water primarily from seasonal precipitation and from wastewater collected from the city of Arequipa and treated at a wastewater treatment plant. A third, smaller source is the CV and SR pit dewatering system, which is mainly used in mine operations. FCX and the Cerro Verde mine believe the operation has sufficient water resources to support current and future operations.

The Cerro Verde mine currently receives electrical power from the National Interconnected Electric System that is primarily sourced under long-term contracts with ElectroPerú S.A. and Engie Energía Peru S.A.

Site operations are adequately staffed with experienced operational, technical, and administrative personnel. FCX and the Cerro Verde mine believe all necessary supplies are available as needed.

### **5 HISTORY**

First activities of the Cerro Verde porphyry copper deposit date back to the late 1800s when artisanal mining produced high-grade oxide ore. In 1917 Anaconda Copper Mining Company acquired the property and operated intermittently until 1970 when the property was nationalized. Minero Perú S.A., a government-controlled mining company, commenced mining and processing of ore with a SX/EW plant and pilot concentrator plant in 1977. The SX/EW plant was among the first in the world to be commissioned.

Minero Perú S.A. sold Cerro Verde to Cyprus Climax Metals Company in 1994. By 1996, remaining ownership included Buenaventura and a variety of individual investors trading their shares on the Lima Stock Exchange. Shortly thereafter, Cyprus invested in improvements to the leach process production. Cyprus Climax Metals Company was

as of December 31, 2022

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

acquired by Phelps Dodge Corporation (PDC) in 1999. By 2004, the SX/EW plant capacity was at 200 million pounds of copper cathode per year (Bernal and Velarde, 2004).

In 2005, SMM Cerro Verde Netherlands B.V. acquired 21 percent ownership, and Buenaventura increased their ownership to 18.3 percent while PDC retained 53.56 percent as part of construction of a primary sulfide concentrator (C1). Production at C1 started in 2006, with a capacity of 108,000 metric tons of ore per day. In 2011, C1 capacity was increased to 120,000 metric tons per day following completion of various debottlenecking projects.

FCX acquired PDC in 2007. In 2007, FCX started a drilling program for deep exploration, infill confirmation, geomechanical, hydrogeological, and condemnation targets. Between 2008 and 2011, more than 200,000 meters were drilled.

Construction of new, additional concentrator facilities (C2) with a nominal capacity of 240,000 metric tons of ore per day was completed in 2016. As a result, the total Cerro Verde concentrating capacity expanded to 360,000 metric tons of ore per day. Recent production trends are exceeding the designed capacities. In 2018, ore processing capacity of C2 was increased to 288,000 metric tons of ore per day.

The Cerro Verde mine is a well-developed property currently in operation, and all previous exploration and development work has been incorporated where appropriate in the access and operation of the property. Exploration and development work is included in the data described in Sections 6 through 11 of this TRS.

## **6 GEOLOGICAL SETTING, MINERALIZATION, AND DEPOSIT**

### **6.1 Regional Geology**

The Cerro Verde district is part of the Paleocene copper-molybdenum porphyry metallogenic belt, which includes non-FCX mines, such as Cuajone, Quellaveco, and Toquepala, and other non-FCX deposits such as Mina Chapi and Don Javier. These deposits are generally aligned parallel to the Nazca Trench and the Incapuquio Sinestral fault system with northwest-southeast orientations as shown in Figure 6.1 (modified from Acosta et al., 2010).

**Figure 6.1 - Incapuquio Fault System Structural Corridor**

![img-0.jpeg](img-0.jpeg)

The regional framework consists of a metamorphic basement. These basement rocks form part of the Arequipa massif, which accreted onto the western margin of Gondwana in the late Proterozoic (Acosta, 2006 and references therein). The basement rocks have been subjected to metamorphic events at 1.9, 1.2, and 0.97 billion years (Wasteneys et al., 1995; Martignole and Martelat, 2003; Pino et al., 2004).

Lower Jurassic volcanic and sedimentary rocks are represented by the Chocolate Volcanics, comprising of a sequence of lava flows of andesitic composition and reddish volcanic breccias with small sedimentary intercalations. Volcanism was followed by the deposition of limestones of the Socosani Formation and siliclastic-calcareous rocks of the Yura Group, as a consequence of accumulation, subsidence, and weathering in the Arequipa basin (Sempéré, et al., 2002; Pino, 2003).

During the Upper Cretaceous - Lower Paleocene, compressional tectonics affected the Arequipa basin (Vicente, 1990) causing the inversion of the volcano-sedimentary basins of the Upper Cretaceous (Cornejo and Matthews, 2001; Zappettini et al., 2001). The northwest-southeast Incapuquio Sinestral fault system facilitated abundant magmatism that is represented by the Toquepala Group (Jacay et al., 2002, Sempéré et al., 2002). Then, in the Lower Paleocene - Eocene (63 to 55 million years) an episode of bimodal volcanism developed, partly under an extensional regime (Benavides-Cáceres, 1999). These rocks are associated with epithermal gold and silver deposits and copper porphyry deposits (Sillitoe et al., 1991). The various magmatic pulses of the Cerro Verde porphyries are associated with these events.

### 6.2 Deposit Geology

The Cerro Verde mining district comprises a copper-molybdenum porphyry cluster that includes a series of deposits (CV, SR, and CN) which are related to calc-alkaline intrusions (dacite to monzonite porphyry) and quartz-tourmaline hydrothermal breccia bodies.

In general, these deposits are low grade and high tonnage, genetically related to igneous epizonal intrusions and characterized by multiple events from a parental magmatic chamber, which are distributed along the Incapuquio fault system corridor.

The three deposits are currently in production with each having similar characteristics. The deposits are differentiated by the level of erosion, alteration intensity, and magmatic history.

Age dates of the rocks within the mine area (Stegen, Barton, and Waegli, 2018) are as follows:

- Tiabaya Granodiorite: 79.9 million years (uranium-lead zircon dating).
- Yarabamba Granodiorite: 61.8 to 62.3 million years (uranium-lead zircon dating).
- Dacite Porphyry, which is part of the Dacite-Monzonite Porphyry suite: 60.9 to 62.4 million years (uranium-lead zircon dating).
- Late Dacite Porphyry: 58.5 to 59.8 million years (uranium-lead zircon dating).
- Fragmental rock at CN: 57.0 million years plus or minus 1.5 million years (potassium-argon sericite dating).

6.2.1 Structural Geology

The CV and SR deposits are located in the core of a gently folded west-northwest striking basement-cored anticline or southwest-tilted structural block. The anticlinal axis parallels the Tinajones fault system, a regional north 60-degree west to east-west striking fault zone/lineament. The influence of this structural zone is reflected in the copper grade distribution at depth.

Technical Report Summary for  
Cerro Verde Mine, Arequipa, Peru

A series of parallel north 60-degree east, steeply northwest dipping faults were mapped in the CV and SR pits. Copper contours at depth also define several north-south trends suggestive of underlying structural control. The general fault pattern in the district suggests a major left-lateral fault zone. No major offsets in copper grade contours have been noted, suggesting that post-mineral faulting was minor in the district. The northwest-trending and southwest-dipping Charcani Gneiss-Yarabamba Granodiorite contact played an important role in the localization of the productive porphyries in the Cerro Verde mine area.

Section line is shown on plan map in Figure 6.3. Elevations are in meters.

Descriptions of the individual units from oldest to youngest are presented below.

The Charcani gneiss consists of leucocratic quartz-feldspar bands alternating with dark biotitic bands, commonly containing magnetite. Elsewhere the rock is a medium to coarse granitoid composed of quartz, orthoclase, biotite, and lesser plagioclase and muscovite.

The Late Cretaceous Tiabaya granodiorite batholith is exposed north of the mine area. According to García (1968), the intrusive has an oval shape with steeply dipping contacts with its long axis trending northwest. The intrusive predates the mineralization but is seldom affected by alteration. According to Kihien (1975), the granodiorite shows minor propylitic and phyllic alteration with anomalous copper values in an area northeast of Cerro Verde. The coarse-grained equigranular rock consists of plagioclase, quartz, potassium-feldspar, hornblende, and biotite.

The Tiabaya and Yarabamba granodiorites are the more evolved facies of the Caldera batholith. Regionally, different units of the batholith display a concentric arrangement with the youngest intrusive at the center of the batholith. The Yarabamba granodiorite is spatially associated with dacite porphyry intrusives and is an important ore host in the Cerro Verde district. In drill hole core, granodiorite has several textural and compositional varieties ranging from granodiorite to tonalite. At least six different units of Yarabamba granodiorite can be distinguished through drill hole logging.

A fine to medium-grained equigranular quartz diorite to tonalite was mapped by Kihien (1975) in an area northeast of the main CV deposit. The quartz diorite is more common in the SR area.

A medium-grained hypidiomorphic granodiorite with a minor amount of small, rounded quartz phenocrysts forms a small stock in SR. Similar quartz-porphyry rocks occur in close

proximity to the main dacite porphyry complexes. A fine-grained microgranite, with a low phenocryst-to-groundmass ratio, is present in proximity to CN.

A late intrusive event is represented by several dacite porphyry units hosting quartz, biotite, and plagioclase. These dacite porphyry apophyses show a close spatial relationship with porphyry copper mineralization at CV and SR. The hydrothermal systems center on separate dacite porphyry hypabyssal intrusives, indicating at least two major dacitic intrusive events took place in the district. The various dacite porphyry phases are identical in mineral composition and crystal size; however, the phenocryst-to-groundmass ratio may vary.

A diorite porphyry, located toward the northern portion of the SR pit, occurs as an endogenous dome, intruding and underlying the contact between Yarabamba granodiorite and dacite porphyry. The roots of this late-phase intrusion have not been located. It is post-alteration and post-mineral.

Late magmatic events resulted in emplacement of multiple narrow dacite dikes in the SR areas and as a north-south dike with an approximate width of 75 meters in the CN area. They are generally barren with little pyrite.

Various hydrothermal breccias are widespread in the CV and SR porphyry systems. CV was formed by at least three coalescing breccia bodies measuring 1,000 meters in a northwest direction. The main characteristic of hydrothermal breccia is the presence of an open space that is filled with a variety of hydrothermal minerals.

### 6.2.3 Alteration and Mineralization

Prograde alteration in the district is associated with the intrusion of the early dacite-monzonite porphyry stock. From the center of the hydrothermal system outward, three alteration zones are recognized:

- A broad development of secondary potassium-feldspar and secondary quartz (potassic alteration).
- Potassium-feldspar with biotite (biotitic potassic).
- A lower-temperature phase that constitutes an external halo of propylitic alteration.

Retrograde alteration constitutes a transitional phase between the late magmatic phase and later the hydrothermal stages of phyllic and intermediate argillic. Retrograde alteration includes the precipitation of silica, replacement of secondary biotite with chlorite, and the development of anhydrite veins. In this phase small quantities of copper are introduced into the system, but it is the main phase for precipitation of molybdenite.

In the Cerro Verde mining district, mineralization is directly linked to multiple igneous intrusive events. The resulting hypogene mineralization is dominantly chalcopyrite with minor bornite. Retrograde events resulted in a slight increase in chalcopyrite and precipitation of molybdenite. Supergene processes formed a profile containing zones of leached capping, oxide copper mineralization, chalcocite enrichment, and a mixed chalcocite-hypogene transition zone. Copper ore types used for resource estimation and material routing are summarized in Table 6.1.

Table 6.1 - Mineralogical Ore Types

| Ore Type | Mineralogy |
| --- | --- |
| Leached Cap | Hematite, goethite, and lesser jarosite |
| Oxide | Chrysocolla, brochantite, and lesser malachite |
| Copper Pitch | Copper-manganese oxides |
| Secondary Sulfide | Chalcocite, covellite |
| Transition Sulfide | Partial replacement of chalcopyrite by chalcocite |
| Primary Sulfide | Chalcopyrite, minor bornite |

The majority of the oxide and secondary sulfide mineralization at CV and SR has already been mined.

The hypogene ore grade shell with a 0.2 percent total copper grade (TCu) is larger and has a greater horizontal to vertical aspect ratio at SR than the CV deposit. The grade shell at CV is more compact with a greater vertical component. Encompassing both deposits, this grade shell measures approximately 5.6 kilometers in length trending northwest-southeast, 1.6 kilometers in width and 2.0 kilometers in depth, based on current drill hole lengths.

There are several breccia types at CV and SR that typically contain elevated copper grades. Mineralization associated with breccias is more prevalent at SR.

Lead, zinc, and arsenic are associated mainly with mineralized faults, veins, and breccias. These elements are included in the geologic modelling because elevated values in the copper concentrates can result in smelter penalties.

CN has very well-developed oxide mineralization. The predominant mineral is chrysocolla with lesser amounts of tenorite and malachite. Mineralization occurs mainly in fractures. Moderate amounts of specularite occur as a replacement of the matrix or as fragments in the tourmaline breccia.

## 7 EXPLORATION

Cerro Verde is a mature mining district with a long history of exploration. The data, methods, and historical activities presented in this section document actions that led to the initial and continued development of the mine but are not intended to convey any discussion or disclosure of a new, material exploration target as defined by S-K1300.

Exploration outside of the current operation is in collaboration with the FCX Exploration Group and incorporated into the geologic model. New drilling was included in the update of the geological resource model to support the mineral reserves and mineral resources. Drilling results added for the model update provide local refinement of the geologic interpretations and grade estimates, but do not materially alter these interpretations and estimates on a district-wide scale.

### 7.1 Drilling and Sampling Methods

The district has been drilled using diamond drill core and reverse circulation (RC) techniques for exploration, infill, geotechnical, hydrogeological, condemnation, and drilling for clay material. Some of these low grade to barren drill holes are not in the immediate mining areas and are not used for resource estimation. Drill holes used for geologic modeling are summarized in in Table 7.1. Approximately 2 percent of the data was obtained from RC drilling.

**Table 7.1 - Summary of Drill Hole Programs**

| Years | Company | # of Holes | Meters |  |  |
| --- | --- | --- | --- | --- | --- |
|  |  |  | Core | RC | Total |
| 1971 to 1975 | Minero Peru | 227 | 80,831 | - | 80,831 |
| 1994 to 1999 | Cyprus | 330 | 64,384 | 13,811 | 78,195 |
| 2000 to 2006 | PDC | 329 | 79,050 | 1,364 | 80,414 |
| 2007 to 2021 | FCX | 1,825 | 605,751 | 3,042 | 608,793 |
| Total |  | 2,711 | 830,016 | 18,217 | 848,233 |

Numbers may not foot due to rounding.

The deepest hole on the property is over 2,000 meters whereas most holes are less than 500 meters deep. At Cerro Verde, 83 percent of drill holes are vertical, 15 percent are angle, and 2 percent are horizontal drain holes.

Historically, sampling was done at irregular intervals depending on the observed mineralization (representing 19 percent of intervals included in the model). Between 1999 and 2009, samples were collected based on drill hole runs which had varying lengths. Starting in 2010, a regular 3-meter sample interval was implemented for vertical holes. Starting in 2020, a regular 3-meter sample interval was implemented for angle holes. Prior to 2020, angle holes were sampled on the downhole distance corresponding to a vertical distance of 3 meters for holes steeper than 45 degrees and the downhole distance corresponding to a horizontal distance of 3 meters for holes flatter than 45 degrees. For example, an 80-degree angle hole would have had a sample interval of 3.05 meters.

## 7.2 Collar / Downhole Surveys

Upon completion of a drill hole, collar locations are surveyed using Global Positioning System (GPS) units. All coordinates are based on the local mine grid system.

Historically, downhole surveys were not systematically performed. For historical holes lacking surveys, the collar azimuth and dip are used for the entire length of the hole. In recent drilling programs, downhole surveys are completed for all angle drilling and for all drill holes exceeding 200 meters in depth.

Currently, core and RC drill holes are primarily surveyed using a single-shot camera method. Surveys are conducted on 30 to 50-meter intervals down the hole. In cases where downhole surveys are not conducted on shallow holes, values from the hole design are used. Downhole surveys are carefully evaluated to review the accuracy of the survey data. Survey data are part of the district-wide database and are used in the modeling process to locate drill hole intercepts.

Final reports for collar and downhole surveys are included in the drill hole log files. Original survey records are stored in a secure facility. Spatial locations of the drill holes are visually validated in the resource modeling software.

## 7.3 Drill Hole Distribution

Core drill holes are typically drilled with a 50-meter grid spacing and a diameter of HQ-size (2.5 inches). Average drill hole spacing increases at depth, so the mine conducts over 10 kilometers of infill drilling on an annual basis. Drill programs are guided by geological and mineralogical characteristics and by the district mining sequence.

Most of the holes drilled in the district are vertical and are distributed along east-west and north-south orientations. Angled holes are drilled to address geological and mineralogical requirements and are used where access to planned drill sites is not available. The distribution of drill holes in the district is shown in Figure 7.1.

#### 7.4 Sample Quality

At the Cerro Verde mine, core drilling is used as the most accurate method for obtaining geological and assay information. Core recovery is generally above 95 percent.

Core samples are sawn and taken on 3-meter intervals from the collar. A geologist is present during RC drilling to log samples and monitor sample quality. RC samples are taken at the drill rig utilizing a cyclone to capture a sample. Split sample analyses show that recovery and grades are representative of the material drilled and show no preferential bias of grades due to sampling methods.

The historical Anaconda drilling is no longer used for geologic resource modeling due to concerns about the quality of the information and the disposal of all corresponding drill hole samples.

## 7.5 Sample Logging

Core logging procedures used at the Cerro Verde mine were developed under the ownership of Minero Peru, Cyprus, PDC, and FCX. Historical logging was done on paper and includes information regarding rock types, structure, mineralization, and alteration.

Currently, geological logging is done on laptop computers. Since 2007, all information is entered into a drill hole database. Information collected includes rock type, alteration type and intensity, mineralization, geomechanical parameters, core recovery, rock quality designation (RQD), point load test data, and specific gravity (SG). Since 2005, high-resolution photographs have been taken for each box of drill hole core prior to logging.

Completed logs are validated, approved, and then printed out and stored on-site for each drill hole.

## 7.6 Hydrogeology

Hydrogeologic work is part of an innovative workflow that allows reconciliation of observed open-pit slope pore pressures against geotechnical targets and predicted depressurization results. The prediction of expected hydrogeologic responses from the existing and planned additions to the piezometer network, horizontal drain holes, and vertical dewatering wells is generated using a three-dimensional numerical groundwater flow model. Hydrogeological modelling is based on continuing work by third-party consultants.

The Cerro Verde mine works to achieve slope depressurization and dewatering goals and continues to update water management plans to intercept groundwater with horizontal drain hole drilling programs for specific slope depressurization needs, annual piezometer and vertical well installation focused on targeted areas, and necessary dewatering rates.

Ongoing hydrogeologic investigation includes:

- Design and implementation of appropriate proactive dewatering and slope depressurization measures including a piezometer network, pilot holes, vertical production wells, and horizontal drain holes.
- Field activities associated with mine dewatering and pit slope depressurization, including RC pilot borehole hydrogeologic logging, airlift and recovery testing and characterization, water quality testing, dewatering well design, and piezometer design and construction.
- Monitoring of production from vertical well and horizontal drain flows, piezometer performance, and pit sump pumping.
- Routine construction and replacement of a groundwater and pore pressure monitoring system utilizing a piezometer network, pilot holes, dewatering wells, and associated pumping and piping infrastructure.

## 7.7 Geomechanical Data

Geomechanical work includes an integrated workflow to manage needs that include field investigation, slope stability studies, mine dewatering, and pit slope depressurization. A comprehensive geology model is used as a baseline to integrate the stability models to hypothesize failure mechanisms, define geomechanical domains, estimate strength parameters, and identify slope depressurization targets.

Technical Report Summary for
Cerro Verde Mine, Arequipa, Peru

The Cerro Verde mine uses limit equilibrium and numerical models to evaluate slope stability and establish annualized depressurization targets required to achieve the slope stability design acceptance criteria for factor-of-safety and strength-reduction-factors. Moreover, stability studies update the recommendations for bench geometries, inter-ramp slope angles, and overall slope configurations. Efforts also include site characterization, material characterization, stability studies, and risk assessment for certain waste dumps and ROM stockpiles. Geomechanical modelling is based on continuing work by third-party consultants.

Televiewer surveying is used on geomechanical holes. A third-party consultant uses the data collected in conjunction with physical examination of the drill hole core to characterize the orientation and properties of the geologic structures.

Ongoing geomechanical investigation includes:

- Design and implementation of appropriate proactive geotechnical measures including geomechanical core drilling, televiewer surveying, cell mapping, photogrammetry, and rock testing.
- Geomechanical core drilling is planned and executed to characterize the orientation and properties of geologic structures with televiewer surveying to obtain geomechanical parameters, rock testing, and install instrumentation.
- Geomechanical models including RQD are used for predicting the spatial variability and assessing rock quality as it relates to the degree of fracturing within the in-situ rock mass.
- Structure data is collected through cell mapping and photogrammetry to characterize the orientation and properties of geologic structures.
- Rock testing quantities are governed by rock quality and sample availability and include, but are not limited to, triaxial tests, uniaxial tests, disk tension tests, and small-scale direct shear tests. Testing is performed in accordance with the American Society of Testing and Materials, the International Society for Rock Mechanics, and the British Standards.
- Routine replacement and addition of geomechanical drill holes in areas of interest.

These activities are supervised and guided by an expert group specialized in mining geomechanics, hydrogeology, mine dewatering, and pit slope depressurization allowing completion of the geomechanical and hydrogeologic activities to established FCX mining geomechanical standards. The group consists of site personnel, FCX Corporate Geomechanical and Hydrogeology teams, primary geomechanical and hydrogeological third-party consultants, external reviewers, and industry experts.

7.8 Comment on Exploration

In the opinion of the QPs:

- The exploration programs completed at Cerro Verde (drilling, sampling, and logging) are appropriate for geologic resource modeling.
- The data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for mineral reserve and mineral resource estimation.
- The geomechanical and hydrogeologic programs are appropriate to support slope design recommendations according to the established slope design criteria and mine plans.

# **8 SAMPLE PREPARATION, ANALYSES, AND SECURITY**

# **8.1 Sampling Techniques and Sample Preparation**

Historically, core samples were split using a manual press splitter. Electric disc splitters were used from 1999 to 2009 with the objective of obtaining a better cut in the sample, avoiding bias, and the loss of fines. Since 2010, semi-automatic core saws have been employed. The core saws are more efficient and provide a representative split of the drill hole intervals.

Sample technicians place one-half of the sample back into the original core box in the same position and direction as it was originally oriented. The other half is placed in a labeled plastic bag, with the name of the drill hole, sample identification, and interval number. Sample weights are approximately 15 kilograms for split HQ-size (2.5 inches) core and 9 kilograms for NQ-size (1.875 inches) core. Drill hole core storage is located in on-site facilities. Core splits and rejects from all drilling programs are stored chronologically, with the exception of the Anaconda drilling programs.

In heavily faulted or other zones of poor core recovery, it is not possible to obtain a representative sample for assay. In these cases, a sample number is assigned but no sample is sent to the laboratories. It is entered in the database as having no recovery or grade.

For RC drilling, a sample is taken each meter from the cyclone. Each group of 3 samples is then combined to form a 3-meter sample. These samples are then taken to the Cerro Verde mine assay laboratory where they are quartered, split, and portioned by weight to produce a single sample weighing approximately 15 kilograms for each 3-meter drill hole interval. The material size for RC samples is approximately a quarter inch.

Samples from core and RC drilling are sent to the Cerro Verde mine assay laboratory for preparation and analysis. Sample preparation is done according to mine site procedures. Wet samples are taken to the sample preparation yard and left at ambient temperature for 3 hours. In case of rain, samples are dried in the oven for approximately 2 hours.

After drying, samples are crushed to minus a quarter inch using a Boyd crusher. Twenty percent of the sample is retained for further processing, while the remaining 80 percent is placed in a new bag for storage. Samples are then pulverized to minus 100 mesh and five pulps of 80 grams. Pulp samples are returned to the Cerro Verde geologists for insertion of quality assurance and quality control (QA/QC) samples, described in Section 8.3. For chain of custody purposes, the names of the individuals delivering and receiving the samples are recorded and stored at the mine site.

# **8.2 Assaying Methods**

Assaying for Minero Peru drill hole samples was performed at the Cerro Verde mine assay laboratory. Selected duplicate verification samples were sent to the SGS Group (SGS) laboratories in Lima, Peru. Cyprus and PDC also conducted assay work at the mine assay laboratory. Grade reports were completed via hand-filled paperwork.

FCX continues to send drill hole samples to the Cerro Verde mine assay laboratory. This laboratory has a Peruvian Technical Standard ISO/IEC certification 17025:2006. In addition, some composites are sent to FCX's Technology Center facilities in Tucson, Arizona, U.S. (TCT). The TCT laboratory is accredited under the ISO 9001:2015 Quality

System. Secondary laboratory samples are sent to Certimin S.A., a third-party laboratory in Lima, Peru, that has a Peruvian Technical Standard ISO certification IEC 17025:2019.

Historically, samples have been analyzed by atomic absorption spectroscopy (AAS). In addition to TCu, samples were analyzed for acid-soluble copper (ASCu) followed by cyanide-soluble copper (CNCu) on the residue from the acid-soluble sample. Since 2008, copper has been analyzed by inductively coupled plasma. Samples exceeding 10,000 parts per million copper are reanalyzed by AAS. Cyanide testing was stopped in 2019 due to safety concerns and replaced with a ferric sulfate-soluble copper assay, known as quick leach test (QLT).

Other elements analyzed include total molybdenum (TMo), total iron (TFe), total arsenic (TAs), lead, sulfur, zinc, silver, gold, and manganese. There is also information on mineral characterization from x-ray diffraction (XRD) and cation exchange capacity. Composite samples for metallurgical recovery tests have mineralogical analyses performed by SGS's quantitative evaluation of minerals by scanning electron microscopy (QEMScan).

### 8.3 Sampling and Assay QA/QC

No written documentation exists for QA/QC procedures used by Minero Peru, Cyprus, and PDC. QA/QC information for these pre-FCX drill holes consisted only of duplicates. Despite the lack of robust QA/QC programs for these holes, no issues have been identified in the geologic and assay information associated with this drilling. Furthermore, a significant portion of the intervals for these holes have been mined out at the Cerro Verde mine.

Current procedures at the Cerro Verde mine for QA/QC on drill hole samples are as follows:

- Standards are inserted on a 1 in 20 basis by Cerro Verde for assay by Cerro Verde mine assay laboratory. These standards were made from primary sulfide mineralization taken from the CV and SR open-pits. This locally sourced material was sent to SGS in Lima, Peru for preparation of sample pulps. SGS's laboratory in Lima has a Peruvian Technical Standard ISO/IEC certification 17025:2017. The standard values are blind to the laboratory and are added to assess accuracy.
- Blanks are utilized and inserted on a 1 in 20 basis to confirm that there is no contamination between samples due to the sample preparation errors at the laboratory. Blanks were prepared and certified by SGS. Certification was based on inter-laboratory analytical results compiled by SGS. Another set of blanks were prepared at the Cerro Verde mine using unmineralized quartz material. The blanks are blind to the laboratory.
- Duplicates are analyzed on a 1 in 20 basis at the splitting (sample) and pulverization (pulp) stages of sample reduction. For core samples, the remaining half of split core, normally reserved for reference and metallurgical testwork, is sent to the laboratory as a duplicate sample. For RC samples, a duplicate sample is collected during drilling from the rig mounted cyclone splitter. The sample duplicates are blind to the laboratory. Each pulp duplicate is taken as a split from the pulverized material of the corresponding sample duplicate. Duplicate results are used to assess analytical precision and to evaluate the sampling nomograph.
- Over the years, random selections of pulp samples were sent to various secondary laboratories for validation of the primary laboratory results, with a targeted insertion rate of 3 to 5 percent.

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

- QA/QC data is entered directly into the drill hole database. All QA/QC check assays are examined for acceptability using QA/QC tools in the database software. Assays that meet QA/QC requirements are accepted into the database; those that did not are rejected, and reruns are ordered from Cerro Verde mine assay laboratory.

#### **8.4 Bulk Density Measurements**

The Cerro Verde mine tests core samples from CV, SR, and CN for density using the immersion method on unsealed pieces of dry drill hole core. One SG measurement is generally made for each 3 meters of core. Sample selection considers various geological criteria such as rock type, alteration, mineralization, fracturing, faulting, and other representative parameters. The weight of the sample in air and weight of the sample in water are entered into the database, providing a SG value for each interval by using the following formula:

$$SG = \text{weight in air} / (\text{weight in air} - \text{weight in water})$$

#### **8.5 Comment on Sample Preparation, Analyses, and Security**

In the QP's opinion, sample preparation, analytical methods, security protocols, and QA/QC performance are adequate and support the use of the analytical data for mineral reserve and mineral resource estimation.

### **9 DATA VERIFICATION**

#### **9.1 Data Entry and Management**

Drill hole information is maintained in a database and managed by a database manager that has full access and the ability to restrict and monitor access for other end users. This database manager coordinates and controls the entry of all geologic information into the district-wide drill hole database.

Analytical data is loaded into the database directly from the laboratory via software importers. Prior to loading, the information is checked and validated. As needed, analytical results are rejected, and the relevant samples are reanalyzed. There is no manipulation of the assay information.

Outlier evaluations are routinely completed for the 3-meter assay intervals and 15-meter composites. The analytical values are compared to visual estimates as a check of the logging quality and the assay values. Assay intervals are validated and checked against the actual sample intervals.

Collar survey data is loaded directly from GPS units into the database. Collar locations are checked against surveyed topographic surfaces. Downhole surveys are examined for anomalous changes in azimuth and dip between adjacent surveys in cross section before they are imported into the database.

For historical drill holes, collar coordinates, downhole surveys, mineralogy and alteration codes, lithology and assays were migrated to the database via manual entry from the original core logging sheets. SG, uniaxial compressive strength, and RQD were entered

from geotechnical logs. The transfer and validity of this data has been frequently checked during various model updates throughout the years.

## 9.2 Comment on Data Verification

As confirmation of the mineral reserve and resource process, third-party consultants are occasionally hired to perform verification studies. The Cerro Verde mine was last reviewed for year-end reporting during 2022. The study concluded that the geological methodologies analyzed “are reproducible, and therefore auditable, and are supported by procedures, protocols and standards used by the industry.”

The QP has been involved in recent model audits of the Cerro Verde mine including reviews of the drill hole data. The data has been verified and no limitations have been identified.

In summary, data verification for the Cerro Verde mine has been performed by mine site and FCX corporate staff, and external consultants contracted by FCX. Based on reviews of this work, it is the QP’s opinion that the Cerro Verde mine drill hole database and other supporting geologic data align with accepted industry practices and are adequate for use in mineral reserve and mineral resource estimation.

## 10 MINERAL PROCESSING AND METALLURGICAL TESTING

Mineral reserves and mineral resources are evaluated to be processed using hydrometallurgy and/or concentrating (mill) operations. The applicable processes and testing are discussed below.

### 10.1 Hydrometallurgical Testing and Recovery

Hydrometallurgical recovery is estimated based on the recoverable copper content and the time required to extract the recoverable copper. The final recovery is realized only after multiple leaching passes or cycles on the stockpiles. A leach cycle consists of solution application to a leach pad, followed by a rest period without solution application. Subsequent leach cycles recover diminishing portions of remaining copper.

Hydrometallurgical recoveries at the Cerro Verde mine have been developed from a combination of assay results to determine the range of mineral solubilities, column leach testing using standardized practices by the on-site laboratory and monitoring of field results. Recoverable copper content and kinetic recovery curves vary by ore type and applied leach cycles. Leach production results are tracked over many years to confirm actual hydrometallurgical recoveries. The range of expected long-term leach recoveries by process is listed in Table 10.1 for hydrometallurgy operations.

**Table 10.1 - Hydrometallurgical Recoveries**

| Hydrometallurgical Method | Estimated Copper Recovery (%) |
| --- | --- |
| Crushed Leach | 70 to 82 |
| ROM Leach | 41 to 70 |

Historical recovery estimates have been based on CNCu assays. This assaying method was eliminated in 2019 due to safety concerns. Analysis was undertaken to replace CNCu with QLT in the leach recovery equations for the range of mineral solubilities. No material

differences were identified between recovery methodologies. The original recovery equations based on CNCu continue to be utilized for material lacking QLT data, since the original information is available and remains valid. QLT based equations are utilized where data is available.

Field results are a combination of ore type deliveries to the leaching processes. Actual results of the aggregate copper recovery compare favorably to the estimated recoveries, and it is the QP's opinion that the recovery estimates and kinetic recovery curves are reasonable.

## 10.2 Concentrating Metallurgical Testing and Recovery

Metallurgical testing and development activities were undertaken during 2003 and 2004 to support the initial C1 concentrator development. Much of the metallurgical testwork performed by PDC and third-party laboratories was done on variability samples or composites representing the different ore types. The parameters from the testwork were used as inputs to predictive performance models for the plant, in terms of throughput in the comminution circuit, metal recovery, and concentrate grade in the flotation circuits. The testwork and engineering studies ultimately led to the construction and commissioning of the C1 concentrator in early 2007.

The C2 concentrator was commissioned in late 2015. The design and construction were based on the original testwork for C1, with additional trade-off studies and the operating data from C1 to improve parts of the circuit.

Current predictive plant performance models have been based on operating results more than initial testwork, especially with respect to the tonnage capability of the plants, which have exceeded the original design criteria for the concentrators. The historical performance of the plants helps to define the capability of the plant but does not confirm future performance.

The Cerro Verde mine also relies on a geometallurgical testwork program to determine the characteristics of future ores. The majority of the geometallurgical testwork was completed by the Cerro Verde mine laboratory. Geometallurgical campaigns are designed to focus on ore to be processed in the next 5 years of operation, with a smaller number of samples covering the expected future ores deliveries to compare to the ore currently being processed. The testwork includes flotation tests, Bond Work Index (BWI) testing, and mineralogical analysis including QEMScan and XRD.

The QA/QC procedures for the hardness testing include repeats, duplicates, and a laboratory round-robin verification program. For flotation testing the main QA/QC methodology is by use of repeats and duplicates.

Metallurgical recovery of copper and molybdenum considers three ore types, namely primary sulfides, secondary sulfides, and transitional sulfides. Recovery estimates have been developed by ore type for the district and are supported by analytical testing at the operation along with field results. The long-term metal recovery estimates by ore type are listed in Table 10.2 for concentrator operations.

**Table 10.2 - Concentrator Recoveries**

| Ore Type Description | Copper Recovery (%) | Molybdenum Recovery (%) |
| --- | --- | --- |
| Primary Sulfides | 90 | 55 |
| Secondary Sulfides | 85 | 52 |
| Transitional Sulfides | 85 | 52 |
| Stockpiled Ore | 65 | 52 |

Silver is a by-product of the copper concentrate produced and is recovered in the smelter.

From 2015 to 2022, metallurgical recovery of copper has been affected by a high percentage of ore feed from previously stockpiled ore. This ore is primarily comprised of oxidized sulfide material with a lower realized recovery than the original testwork. The current stockpile inventory is planned to be depleted by 2028 in the LOM plan and primary sulfide ore will be the majority of ore feed deliveries. As a result, future metallurgical recovery is expected to better align with the estimates of the ore types.

Arsenic is present in the ore but does not occur in the copper concentrates at levels above the contract specifications. Arsenic can occur at levels above contract specifications in the molybdenum concentrate. The Cerro Verde mine manages this material through blending of concentrates with lower levels of arsenic so that the final product is shipped within contract specifications.

While there are some isolated areas of high zinc and lead in the mine, neither the copper nor the molybdenum concentrates are impacted by these impurities.

### 10.3 Comment on Mineral Processing and Metallurgical Testing and Recoveries

In the opinion of the QPs, the metallurgical testwork completed has been appropriate to establish reasonable processing methods for the different mineralization encountered in the deposits. Geometallurgical samples are properly selected to represent future ores and recovery factors have been confirmed from production data collected from ore processed in the open-pits. As a result, the processing and associated recovery factors are considered appropriate to support mineral reserve and mineral resource estimation and mine planning.

## 11 MINERAL RESOURCE ESTIMATE

Mineral resources are evaluated using the application of technical and economic factors to a geologic resource block model and employing optimization algorithms to generate digital surfaces of mining limits, using specialized geologic and mine planning computer software. The resulting surfaces volumetrically identify material as potentially economical, using the assumed parameters. Mineral resources are the resultant contained metal inventories.

### 11.1 Resource Block Model

Relevant geologic and analytical information is incorporated into a three-dimensional digital representation referred to as a geologic resource block model. The Cerro Verde mine resource block model was updated on March 23, 2022, with an effective date for exploration drill hole data of December 1, 2021. The Cerro Verde resource block model

as of December 31, 2022

39

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

includes rock type and mineralogical ore type interpretations for the Cerro Verde district based on drilling and projections from production data and interpolation parameters which distinguish geostatistical domains.

### 11.1.1 Compositing Strategy

Drill hole assay intervals are combined into 15-meter composites, corresponding to the mine bench height. Composites are broken on lithological contacts, with a minimum length of 7.5 meters. If the composite length is shorter, it is added to the previous composite. The purpose of breaking composites on lithological contacts is to retain the correlation between samples and composites. This was done for TCu, ASCu, and QLT.

For analytes such as TMo, TFe, TAs, and others, a separate bench composite is created to facilitate merging calculated composites with analytical composites. If any portion of a drill hole is flatter than 48 degrees, the compositing program reverts to 15-meter fixed-length composites.

Geological codes are composited by majority code. These codes may be edited manually based on the results of outlier analysis for each rock type and mineral type.

### 11.1.2 Statistical Evaluation

Exploratory data analysis of the composites serves to identify populations for the various analytes to be estimated and checks for trends and extreme values. This analysis is based on cumulative probability plots, QQ plots, histograms, box plots, scatter plots, and basic statistics by each geological domain. Contact analysis is performed to determine the nature of boundaries between geologic domains as either hard or soft.

Numerous statistical studies over the years have demonstrated that ore types based on copper mineralogy comprise distinct populations for copper in the oxide and supergene zones. In the CV deposit, the oxide zone has the highest TCu grades, followed by secondary and primary sulfides. In the SR deposit, secondary sulfides have the highest TCu grades, followed by oxide and primary sulfides. The primary sulfide grades for CV and SR are very similar. For primary sulfide mineralization, late-stage porphyry intrusions are distinctly lower grade while breccias are higher grade. Down hole and direction variograms are used to define anisotropy for Ordinary Kriging (OK).

### 11.1.3 Block Model Setup

Model limits and block sizes for the geologic resource block model are shown in Table 11.1. East and west coordinates are truncated Universal Transverse Mercator coordinates where 200,000 has been subtracted from east coordinates and 8,100,000 has been subtracted from north coordinates. Elevation is in meters above sea level and the vertical block size matches the mine bench height for open-pit operations. The model has not been rotated and the extent of the model encompasses the CV, SR, and CN deposits.

**Table 11.1 - Cerro Verde Block Model Parameters**

| Direction | Minimum | Maximum | Size (meters) | # of Blocks |
| --- | --- | --- | --- | --- |
| X-East | 20,300 | 28,300 | 20 | 400 |
| Y-North | 67,000 | 73,400 | 20 | 320 |

#### 11.1.4 Topography

Geological interpretations and grade estimates are carried to the original topographic surface in the geologic resource model. The original topography is from Anaconda and is based on aerial photography. Estimated year-end topography is constructed from site surveys and estimated mining progress. Volumes between the estimated year-end topographic surface and the in-place, hard-rock surface are coded as fill material.

#### 11.1.5 Geologic Model Interpretation

Rock type interpretations are developed on 129 east-west sections, 161 north-south sections, and 168 mid-bench plans. Sections are spaced 50 meters apart while bench plans are 15 meters apart. Interpretations are reconciled in all three directions. After final checks and minor editing, the mid-bench plan polygonal shapes are used to code the model using the majority percentage for the block.

Interpretations for copper mineral types and alteration are developed in the same way as for rock type. Rock type and mineral codes are used to define interpolation domains for grade estimation.

#### 11.1.6 Grade Estimates

The grade interpolation search distances for OK, Inverse Distance Weighting (IDW), and Nearest Neighbor (NN) methods are based on the statistical and geostatistical analyses. Model items for TCu, TMo, ASCu, and QLT are all estimated in the same set of runs using OK. Model items for TAs, RQD, and BWI are estimated using IDW with a power of 3. NN values are utilized to check the interpolated values.

Mineral types for copper are the main control for interpolation of TCu, ASCu, and QLT for non-hypogene mineralization. For hypogene mineralization, copper grade shells and rock types are used to constrain the interpolations. Search distances are 200 meters by 200 meters by 60 meters in X, Y, and Z directions for most interpolation domains. Smaller domains have shorter distances. Separate estimation parameters have been developed for CV, SR, and CN.

#### 11.1.7 Bulk Density

Bulk density was estimated using measured SG values for each drill hole interval composited to 15 meters. A default SG value of 2.698 was assigned for CV and SR, and a default SG value of 2.550 was assigned for CN. Final SG values in the block model were determined using drill hole composite values and NN estimation based on deposit and mineralogic ore types. Search distances for this assignment vary by direction and deposit but do not exceed 200 meters. Beyond this search, averages by deposit are assigned.

#### 11.1.8 Mineral Resource Classification

Drill hole spacing and the number of composites used for interpolation are key components in evaluating the uncertainty of mineral resource estimates. Approximately 98 percent of the drilling at the Cerro Verde mine is core. Suspect drill holes have been identified so as not to be used; therefore, sample type is not a consideration in assessing uncertainty of the mineral resource estimates.

as of December 31, 2022

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

FCX's experience with porphyry copper deposits has established drill hole spacing criteria that provide estimates of ore tonnage, grade, and contained and recoverable metal meeting corporate standards for each process method. The required drill hole spacing considers uncertainty in grade estimates as well as geometric uncertainty associated with geologic interpretation of copper mineral types, rock types, and alteration. Experience has shown that drill hole spacings of 50 and 100 meters are adequate for determination of measured and indicated resources, respectively, and inferred resources can be projected up to 200 meters from a drill hole.

Resource classification criteria are summarized in Table 11.2 for CV and SR and Table 11.3 for CN. The targeted drill hole spacings for measured and indicated resources at CV and SR have been increased by 10 percent to 55 and 110 meters to allow for holes that cannot be placed exactly on grid locations. If a percentage of the variogram range is less than the established distances, it takes precedence. In most cases, the variogram ranges are longer than the average distance criteria.

**Table 11.2 - Resource Classification Criteria for CV and SR**

| Domain | Resource Classification | Variogram Range |  | Average Distance (meters) | Minimum # of Composites | Minimum # of Holes |

Not classified: Greater than 100 percent of variogram range or distance greater than 200 meters

### 11.1.9 Model Validation and Performance

The geologic resource model is evaluated by visual inspection, statistical analysis, and comparison with the blast hole model. Reconciliations between the resource model and blast hole models provide a measure of uncertainty associated with mineral resource classification.

Cross sections and level plans showing block model codes and drill hole composites are visually examined to verify proper coding of rock type, alteration, and mineral type. Similarly, block model grades are compared with supporting composite values. These inspections show that block model values compare well with the drill hole composites.

Comparisons among assay, composite, and block model grades are performed for each mineralogical ore type as an integral part of the model process. Estimated grades in the model are evaluated by statistical analyses including cumulative probability plots of assays, composites, and blocks. The cumulative probability plots are developed to review that the block grade distributions mimic the distributions of the underlying data. Block model OK and IDW results are compared with the composite data and NN estimates.

As confirmation of the mineral reserve and resource process, third-party consultants are occasionally hired to perform verification studies. The Cerro Verde mine was last reviewed for year-end reporting during 2022. The study concluded that the geological methodologies analyzed “are reproducible, and therefore auditable, and are supported by procedures, protocols and standards used by the industry.”

FCX standards provide that the resource model should be within 10 percent of the blast hole model for tonnage, grade, and contained or recoverable metal over a 12-month period. For sites such as the Cerro Verde mine with multiple processing methods, comparisons are made for each, but consideration is given to the processing method that represents the greatest proportion of production. As of December 31, 2022, the comparison between the resource model and blast hole model indicate that the resource model is underpredicting in molybdenum grade; however, over a 36-month period, the model meets FCX criteria. Reconciliation data is routinely reviewed, and action plans are administered to investigate noted variances.

Cerro Verde Mine, Arequipa, Peru

11.1.10 Comment on Geologic Resource Model

The Cerro Verde mine has a long history of mining and has been the subject of numerous geological studies. In the opinion of the QP, who is a member of the FCX Resource Model Audit Team and has participated in reviews of the most recent model updates:

- The Cerro Verde geology staff has a good understanding of the lithology, structure, alteration, and copper mineral types in the district. The understanding of the controls on mineralization are adequate to support estimation of mineral reserves and mineral resources.
- The understanding and interpretation of ore types based on copper mineralogy is a key component to supporting classification of mineral reserves and mineral resources by process method.
- The geological knowledge of the district is sufficient to provide reliable inputs to mine planning, geomechanics, and metallurgy.
- The geologic resource model has been completed using accepted industry practices.
- The geologic resource model is suitable for estimation of mineral reserves and mineral resources.

11.2 Resource Evaluation

Mineral resource estimates are developed by applying technical and economic modifying factors to the geologic block model to identify material with potential for economic extraction. The process of evaluation is iterative, involving an initial draft using the assumptions, understanding the implications of the resulting economical mining limits, and adjusting the assumptions as warranted for subsequent evaluations.

Mineral resource estimates are determined using measured, indicated, and inferred classified materials as viable ore sources during evaluations with the modifying factors.

11.2.1 Economic Assumptions

FCX executive management establishes reasonable long-term metal pricing to be used in determining mineral reserves and mineral resources. These prices are based on reviewing external market projections, historical prices, comparison of peer mining companies' reported price estimates, and internal capital investment guidelines. The long-term sale prices align the company's strategy for evaluating the economic feasibility of the mineral reserves and mineral resources.

The mineral reserves and mineral resources are based on specific volumes of potentially economic, mineralized material in which FCX has the most confidence to produce an acceptable economic result, given a set of evaluation assumptions. As work continues to increase FCX's confidence through drilling, test work, and the evaluation of engineering work and other modifying factors, FCX anticipates conversion of resources to reserves in the future, which may require, among other things, higher metal prices.

In developing the economic assumptions used to determine mineral reserves and mineral resources during early 2022, FCX and its QPs made comparisons of the commodity price assumptions against various periods of historical average prices and current spot prices. Additionally, long-term forward-looking price projections from various sources of third-party market consensus services and financial institution reports covering periods ranging from 2022 to 2035 were reviewed. This information is used as reference for

as of December 31, 2022

44

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

reasonableness of the assumptions. FCX concluded that mineral reserve price assumptions of $3.00 per pound for copper, $12 per pound for molybdenum, and $20 per ounce for silver were reasonable in comparison to the reference points and expected volumes of potentially economic material. FCX also concluded mineral resource price assumptions of $3.50 per pound for copper, $15 per pound for molybdenum, and $20 per ounce for silver were reasonable and aligned with industry-accepted practice to use higher metal prices for the mineral resource estimates than the pricing used for determining mineral reserves.

For copper, London Metal Exchange copper settlement prices over various historical periods were reviewed. For the 10-year period ended December 31, 2022, the price ranged from $1.96 per pound to $4.87 per pound and averaged $3.06 per pound. During 2022, forward-looking prices ranged from $2.70 per pound to $4.08 per pound.

For molybdenum, weekly average molybdenum prices quoted by Platts Metals Daily over various historical periods were reviewed. For the 10-year period ended December 31, 2022, the price ranged from $4.46 per pound to $31.37 per pound and averaged $10.97 per pound. During 2022, forward-looking prices ranged from $8.00 per pound to $13.00 per pound.

For silver, London PM silver prices over various historical periods were reviewed. For the 10-year period ended December 31, 2022, the price ranged from $12.01 per ounce to $32.23 per ounce and averaged $19.20 per ounce. During 2022, forward-looking prices ranged from $14.00 per ounce to $24.79 per ounce.

Unit costs are derived from current operating forecasts benchmarked against historical results and other similar operations. Additional input from appropriate internal FCX departments such as Global Supply Chain, Sales and Marketing, and Finance and Accounting are considered when developing the economic assumptions.

To recognize the relationship between commodity prices and principal consumable cost drivers, FCX scales unit costs to reflect the cost environment associated with the reported metal prices. This is evidenced in the differences in economic assumptions between mineral reserves and mineral resources.

The metal price and cost assumptions are used over the timeframe of the expected life of the mine and reflect steady-state operating conditions in the metal price cost environment. Details of the economic assumptions are outlined in Table 11.4.

### 11.2.2 Processing Recoveries

Processing recoveries are outlined in Section 10.

### 11.2.3 Physical Constraints

Slope angle recommendations are provided by FCX geomechanical groups and third-party consultants. The recommendations are derived from empirical analysis of geological and hydrogeological modeling, drill hole results, and in-field measurements.

Boundary limits for resource evaluation include property ownership and permitting limits, and additional major infrastructure relocation requiring capital investment for boundary expansions.

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

#### 11.2.4 Time-Value Discounting

To recognize the time delay in extracting increasingly deeper portions of the mine as part of the mining process, FCX uses bench discount factoring for resource evaluation processes. This factor discounts each block's value relative to the block's elevation in the geologic block model, effectively assigning a higher relative value to material located closer to the surface than deeper material, which cannot be accessed until overlying material has been removed.

Additionally, hydrometallurgical processes achieve final recoveries after a period of years of repeated solution applications whereas concentrating process recoveries are realized on a more immediate timeframe. In recognition of this distinction, a time-value discount is applied to hydrometallurgical recovery based on the planned recovery curves.

#### 11.2.5 Cutoff Grades

A cutoff grade is used to determine whether material should be mined and if that material should be processed as ore or routed as waste. The mine planning software evaluates the revenue and cost for each block in the block model to determine routing, selecting material that has a reasonable basis for economic extraction using the provided assumptions. The following formula demonstrates how the cutoff grades are determined within the software:

$$\begin{aligned} \text{Internal cutoff grade} &= \text{Sum of [processing costs + general site and sustaining costs]} \\ &\text{/ Sum of [payable recoverable metal * (metal price - metal refining and sales costs)]} \end{aligned}$$

A break-even cutoff grade calculation is similar to the internal cutoff grade formula but includes mining costs. Blocks with grades above the break-even cutoff grade generate positive value, while blocks with grades above the internal cutoff grade minimize negative value. The cutoff grades reported for mineral resources reflect the internal cutoff grades based on economical destination routing from the software results.

Input parameters are applied to individual deposits and distinct ore types as appropriate. Unique parameters can result in distinct cutoff grades. Cutoff grades are reported in terms of an Equivalent Copper Grade (EqCu) defining the relative value of all commercially recoverable metals in terms of copper by ore processing methods.

#### 11.2.6 Economic and Technical Assumptions

The economic and technical assumptions used for the generation of potentially economical mining limits are summarized in Table 11.4.

### 11.3 Mineral Resource Statement

The mineral resource estimate is the inventory of material identified as having a reasonable likelihood for economic extraction inside the mineral resource economical mining limit, less the mineral reserve volume, as applicable. The modifying factors are applied to measured, indicated, and inferred resource classifications to evaluate commercially recoverable metal. As a point of reference, the in-situ ore containing copper, molybdenum, and silver metal is inventoried and reported by intended processing method.

The reported mineral resource estimate in Table 11.5 is exclusive of the reported mineral reserve, on a 100 percent and pro rata property ownership basis. The mineral resource estimate is based on commodity prices of $3.50 per pound for copper, $15 per pound for molybdenum, and $20 per ounce for silver.

- Metal price and other economic assumptions.
- Changes in interpretations of continuity and geometry of mineralization zones.
- Changes in parameter assumptions related to the mine design evaluation including geotechnical, mining, processing capabilities, and metallurgical recoveries.
- Changes in assumptions made as to the continued ability to access and operate the site, retain mineral and surface rights and titles, maintain the operation within environmental and other regulatory permits, and social license to operate.

Uncertainty in geological resource modeling is monitored by reconciling model performance against actual production results, as part of the FCX geologic resource model verification process.

# 11.4 Comment on Mineral Resource Estimate

The mineral resource estimate has been prepared using industry accepted practice and conforms to the disclosure requirements of S-K1300. Mineral reserve and mineral resource estimates are evaluated annually, providing the opportunity to reassess the assumed conditions. Although all the technical and economic issues likely to influence the prospect of economic extraction of the resource are anticipated to be resolved under the stated assumed conditions, no assurance can be given that the estimated mineral resource will become proven and probable mineral reserves.

# 12 MINERAL RESERVE ESTIMATE

Mineral reserves are summarized from the LOM plan, which is the compilation of the relevant modifying factors for establishing an operational, economically viable mine plan. The LOM plan incorporates:

- Scheduling material movements for ore and waste from designed final mining excavation plans with a set of internal development sequences, based on the results of the resource evaluation process.
- Planned production from scheduled deliveries to processing facilities, considering metallurgical recoveries and planned processing rates and activities.
- Capital and operating cost estimates for achieving the planned production.
- Assumptions for major commodity prices and other key consumable usage estimates.
- Revenues and cash flow estimates.
- Financial analysis including tax considerations.

Mineral reserves have been evaluated considering the modifying factors for conversion of measured and indicated resource classes into proven and probable reserves. Inferred resources are considered to be waste in the LOM plan. The details of the relevant modifying factors included in the estimation of mineral reserves are discussed in Sections 10 through 21.

The LOM plan includes the planned production to be extracted from the in-situ mine designs and from previously extracted material, known as WIP inventories. WIP includes material on crushed leach and ROM leach pads for processing, and in stockpiles set aside to be rehandled and processed at a future date. WIP is estimated as of December 31, 2022, from production of reported deliveries through mid-year and the expected production to the end of the year.

## 12.1 Cutoff Grade Strategy

The cutoff grade strategy is a result of the mine plan development, determined by the economic evaluation of the mineral reserves via strategic long-range mine and business planning. Operational cutoff grades are determined from the LOM planning results and can vary based on processing throughput expectations, ore availability, future ore and overburden requirements, and other factors encountered as the mine operates. This approach is consistent with accepted mining industry practice. Cutoff grades reported are the minimum grades expected to be delivered to a processing facility.

## 12.2 Mineral Reserve Statement

As a point of reference, the mineral reserve estimate reports the in-situ ore and WIP inventories from the LOM plan containing copper, molybdenum, and silver metal and reported as commercially recoverable metal.

Table 12.1 summarizes the mineral reserves reported on a 100 percent and pro rata property ownership basis. The mineral reserve estimate is based on commodity prices of $3.00 per pound for copper, $12 per pound for molybdenum, and $20 per ounce for silver.

Technical Report Summary for
Cerro Verde Mine, Arequipa, Peru

In the opinion of the QP, risk factors that may materially affect the mineral reserve estimate include (but are not limited to):

- Metal price and other economic assumptions.
- Changes in interpretations of continuity and geometry of mineralization zones.
- Changes in parameter assumptions related to the mine design evaluation including geotechnical, mining, processing capabilities, and metallurgical recoveries.
- Changes in assumptions made as to the continued ability to access and operate the site, retain mineral and surface rights and titles, maintain the operation within environmental and other regulatory permits, and social license to operate.

As confirmation of the mineral reserve and resource process, third-party consultants are occasionally hired to perform verification studies. The Cerro Verde mine was last reviewed for year-end reporting during 2022. The study concluded that “the reserve model, the mineral reserve estimates, and the production plan for the Cerro Verde operation have been developed using standard procedures generally accepted by the mining industry and that the mineral reserves established meet the SEC’s guidelines.”

The positive economics of the financial analysis of the LOM plan demonstrate the economic viability of the mineral reserve estimate.

### 12.3 Comment on Mineral Reserve Estimate

The mineral reserve estimate has been prepared using industry accepted practice and conforms to the disclosure requirements of S-K1300. Mineral reserve and mineral resource estimates are evaluated annually, providing the opportunity to reassess the assumed conditions. All the technical and economic issues likely to influence the prospect of economic extraction are anticipated to be resolved under the stated assumed conditions.

Mineral reserve estimates consider technical, economic, environmental, and regulatory parameters containing inherent risks. Changes in grade and/or metal recovery estimation, realized metal prices, and operating and capital costs have a direct relationship to the cash flow and profitability of the mine. Other aspects such as changes to environmental or regulatory requirements could alter or restrict the operating performance of the mine. Significant differences from the parameters used in this TRS would justify a re-evaluation of the reported mineral reserve and mineral resource estimates. Mine site administration and FCX dedicate significant resources to managing these risks.

13 MINING METHODS

The Cerro Verde mine has a long operational history and mining conditions are well understood by the site and FCX corporate staff. The mining method is a conventional truck and shovel, open-pit operation.

13.1 Mine Design

The results of the economical mining limit evaluation discussed in Section 11 are used as guides to develop the final mine design and the phased pushback designs for mine sequencing. Mine designs are developed using specialized mine design computer software.

### 13.1.1 Pit Slope Design Parameters

Slope angle recommendations are determined and reviewed by FCX engineers and third-party consultants. These recommendations are based on comprehensive geomechanical testing, studies, and the geomechanical monitoring procedures in the field.

Haul roads and geomechanical catchment berms or step-ins, in conjunction with the recommended inter-ramp slope angles, determine the overall pit slope angles for the design. Inter-ramp slope angles account for differences in rock quality and can include single or double bench designs and various catch bench widths. Thirteen geotechnical domains have been defined at the pit areas, each with different design inter-ramp slope angles. The inter-ramp slope angles vary between 38 to 52 degrees.

Figure 13.1 provides the geotechnical domain areas for the Cerro Verde mine. Pit wall slopes are designed with inter-ramp slope angles assigned to each of those domains.

**Figure 13.1 - Geotechnical Domains**

![img-0.jpeg](img-0.jpeg)

### 13.1.2 Geomechanical and Hydrological Modeling

Geomechanical and hydrological modeling is discussed in Section 7.

The performance of the open-pit wall slopes is monitored with a network of geomechanical and hydrogeological instrumentation. The Cerro Verde mine uses instrumentation that includes slope stability radars, laser scanners, satellite monitoring, extensometers, inclinometers, time domain reflectometry, piezometers, seismic blast monitoring, GPS tracking, and robotic survey stations. Groundwater and pore pressure are controlled with dewatering wells and horizontal drain holes for specific slope depressurization needs as the pit area increases during the life of the mine. The monitoring plan defines responsibilities and outlines the monitoring procedures and trigger points for the initiation

of specified remedial measures if movement is detected, and it is the basis for the design of any required remedial measures.

### 13.1.3 Final Mine Design

Using specialized computer software, mine designs are developed with key considerations that include:

- Compliance with the geomechanical recommendations.
- Reasonable haul road widths and effective grades.
- Operational bench height that is safely manageable with the loading equipment, in single and/or double bench configurations where allowable.
- Adequate mining width for practical mining.
- Locating pit exits near to material destinations as practical.
- Infrastructure location requirements and other boundary restrictions.
- Mine sequencing that maintains continuous production throughout the mine life.

Mine designs are reviewed for compliance to key parameters and reasonableness with comparison to historical and current operating practices. The reserve final mine design is illustrated in Figure 13.2.

**Figure 13.2 - Final Mine Design**

![img-1.jpeg](img-1.jpeg)

The final mine design for the CV and SR open-pit is approximately 2.8 kilometers in width (northeast-southwest) and 5.3 kilometers in length (northwest-southeast). The expected depth of the pit is about 1,200 meters ranging from 1,538 to 2,768 meters above sea level. The CN open-pit design is approximately 1.0 kilometer in width (northeast-southwest) and 1.5 kilometers in length (northwest-southeast). The expected depth of the pit is 270 meters with open-pit exit elevations at approximately 2,800 meters above sea level. Mining is

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

designed to take place on 15-meter benches, with pit slopes allowing for double bench configuration where feasible.

The haul ramps are planned with widths of 35 to 40 meters and with a 10 percent grade but can vary in different sections of the ramp. They are designed to accommodate the current truck fleets.

### **13.2 Mine Plan Development**

The mine plan is developed based on supplying ore to the processing facilities considering equipment production rates, the mining advance rate through the deposit, ore/waste routing, waste stripping requirements, material storage facility capacities, and expansion opportunities. LOM plan schedules are developed using specialized mine planning software.

The mine plan is developed utilizing measured and indicated mineral resource material only. Resource material that is classified as inferred within the mine design is considered waste for LOM planning and mineral reserve estimation.

The deposit is a typical disseminated porphyry type copper deposit, where contact dilution is incorporated into the grade estimation process. As a result, no additional dilution assumption is applied.

Mining ore block recovery is directly related to the mining dilution. Mining recovery in open-pit mines tends to be very high, particularly in disseminated deposits associated with large loading equipment. As result, mining ore block recovery is assumed at 100 percent.

The mine plan is scheduled to ramp up to deliver a targeted average mill production rate of 420,000 metric tons of ore per day by 2026 through 2044, then reduce to 300,000 metric tons of ore per day when C1 ceases production. The average leach production rate is 25,000 metric tons of ore per day through 2023 for crushed leach and ROM leach deliveries are variable through 2044 as material is available. The LOM plan stripping ratio (waste tonnage to ore tonnage) at the Cerro Verde mine is 1.08. Mining activities are projected to end in 2052, when the current reserves are expected to be exhausted.

The mine production rate and expected mine life are illustrated in Figure 13.3.

![img-2.jpeg](img-2.jpeg)

The LOM plan does not include plans for underground development or backfilling of the open-pit although future studies could prove these options as viable improvements to the mine plan development.

### 13.3 Mine Operations

Mine unit operations include drilling, blasting, loading, hauling, and auxiliary support.

Primary production equipment is used to mine ore and waste and as of December 31, 2022 comprises of 17 blast hole drills, 13 electric rope shovels with bucket sizes ranging from 33 to 57 cubic meters, 2 hydraulic shovels with a bucket size of 21 cubic meters, 3 front end loaders, and 154 haul trucks. The truck fleet is comprised of 93 units with a 245-metric ton payload factor, 54 units with a 300-metric ton payload factor, 3 units with a 360-metric ton payload factor, and 4 units with a 363-metric ton payload factor. The primary production equipment is supported by a fleet of ancillary equipment including track dozers, wheel loaders, motor graders, backhoes, and water trucks. Support equipment is used for building access roads, road maintenance, and other mine services.

The LOM plan includes equipment units up to 14 electric rope shovels and 194 haul trucks with a 245-metric ton payload factor. Mine equipment is replaced or rebuilt after its useful life is achieved. Costs for mine equipment replacements and additions are accounted for in the financial modeling.

The site is in operation with experienced management and sufficient personnel. The mine operates 365 days per year on a 24 hour per day schedule. Operational, technical, and administrative staff are on-site to support the operation. As of December 31, 2022, mine operations have 2,765 employees with additional contractors available as needed.

# **14 PROCESSING AND RECOVERY METHODS**

The process facilities operate 365 days per year with exceptions for maintenance. The facilities have a long operating history. FCX and the Cerro Verde mine anticipate that the site will have adequate energy, water, process materials, and permits to continue operating throughout the LOM plan. Figure 14.1 illustrates an overview process map.

**Figure 14.1 - Site Process Diagram**

![img-3.jpeg](img-3.jpeg)

Ore can be directed through hydrometallurgical or concentrating facilities. The hydrometallurgical operation consists of crushed and ROM leach pads, stacking equipment for ore placement, a SX plant consisting of five SX trains, and an EW facility with two cell lines. The hydrometallurgical process produces a high-quality copper cathode.

Primary and certain secondary and transitional sulfide ores are processed in the concentrators, which produce copper and molybdenum concentrates. The C1 concentrator was commissioned in late 2006, with a design capacity of 108,000 metric tons of ore per day, and the C2 concentrator was commissioned in late 2015 with a design capacity of 240,000 metric tons of ore per day. Actual performance and ongoing debottlenecking activities support the LOM plan achieving a combined concentrator capacity of up to 420,000 metric tons per day.

The C1 concentrator has one line of comminution equipment and the C2 concentrator has two lines of comminution equipment, with each line consisting of a primary gyratory crusher, secondary cone crushers, tertiary high-pressure grinding roll (HPGR) crushers, and ball mills. The ore is floated in rougher and cleaner flotation circuits to produce a bulk copper-molybdenum concentrate. The copper-molybdenum concentrate is sent to a molybdenum flotation plant to produce a molybdenum concentrate and a final copper concentrate. All concentrates are dewatered before transport.

These processing methodologies are accepted industry practices for the types of mineralization found at the mine site and are supported by recovery results.

#### 14.1 Hydrometallurgical Processing Description

Oxide, and secondary and transitional sulfide ores from the mine are delivered to leach pads. The SX/EW plant is designed to extract copper from the pregnant leach solutions (PLS) collected from the site's leach pads. Copper is extracted from the ores by using a grid solution system to deliver an aqueous solution containing acid from the plant, called raffinate, to the leach pads. As this acidic solution passes through the heaped material, it extracts copper in the form of copper ions in the PLS.

The PLS is delivered to the SX/EW plant via collection ditches, ponds, and pumping systems. The process takes PLS and extracts the copper ions in extraction mixer-settlers. The copper is extracted via a liquid ion-exchange reagent carried in diluent. A chemical reaction selectively causes the copper to transfer from the PLS to the organic phase. The barren raffinate leaving the SX plant is pumped to the leach pads to extract additional copper from the stacked ore. The loaded organic phase is separated and flows to a strip mixer-settler where the copper is transferred from the organic to the electrolyte that is circulated to the EW plant.

The electrolyte is filtered and heated before being passed through the EW cells where the copper is plated onto copper starter sheets. Once an adequate amount of copper has been plated out of solution as cathodes, these are removed from the cells, washed, and the copper sheets are mechanically harvested. Figure 14.2 illustrates the hydrometallurgical copper transfer process.

**Figure 14.2 - Hydrometallurgical Transfer Process**

![img-4.jpeg](img-4.jpeg)

A diagram illustrating the Cerro Verde mine's hydrometallurgical process is shown in Figure 14.3. The SX plant processes between 1,700 to 5,600 cubic meters per hour of PLS flow and the EW tank house cathode production capacity is approximately 200 million pounds per year.

Hydrometallurgical recoveries are tracked from the leach stockpiles through to the production of copper cathode. Items that can affect the rate of recovery through the stockpiles include, but are not limited to, application rate and method, particle size, leach cycle (i.e., days under leach), acid addition and consumption, solution chemistry, ore type and mineralization, pyrite content, stacking methodology, and stacking height.

Recoveries are tracked over multiple years. Additionally, performance is reviewed periodically through FCX corporate audits to monitor that recoveries are on track to being achieved and continue to be appropriate.

## 14.2 Concentrator Processing Description

Primary and certain secondary and transitional sulfide ores are processed in the concentrators, which produce copper and molybdenum concentrates. The C1 concentrator facility is located north of the CV and SR open-pits. The C2 concentrator facility is located south of the CV and SR open-pits. The ore is processed using the same technology for both concentrators. C1 and C2 concentrators include multi-stage crushing, ball mill grinding, and flotation separation circuits.

The C1 crushing circuit equipment consists of 1 primary gyratory crusher, 4 secondary cone crushers in closed circuit with 4 dry vibrating screens, and 4 tertiary HPGR crushers in closed circuit with 8 wet vibrating screens. The grinding circuit consists of 4 parallel lines each fed by 2 of the screens. Each line of grinding comprises of 1 ball mill, 1 cyclone feed pump, and 1 cyclone cluster. Ground ore is processed in 4 parallel trains of conventional tank cells making up the rougher/scavenger flotation circuit.

The C2 crushing circuit equipment consists of 2 primary gyratory crushers, 8 secondary cone crushers in closed circuit with 8 dry vibrating screens, and 8 tertiary HPGR crushers in closed circuit with 12 wet vibrating screens. The grinding circuit consists of 6 parallel

lines each fed by 2 of the screens. Each line of grinding comprises 1 ball mill, 1 cyclone feed pump, and 1 cyclone cluster. Ground ore is processed in 6 parallel trains of conventional tank cells making up the rougher/scavenger flotation circuit.

For each concentrator the rougher and scavenger concentrates are reground and cleaned in two stages of column cells and tank cells. Each concentrator also has a re-cleaner circuit designed to increase recovery of molybdenum. Flotation concentrate reports to the molybdenum plant for separation of the copper and molybdenum sulfide minerals. The concentrate produced in the plant is the molybdenum concentrate and tailings from the plant is the final copper concentrate. Figure 14.4 provides a simplified process flow diagram of the mill.

**Figure 14.4 - Mill Process Diagram**

conditions in the plants. Table 14.1 includes the typical ranges of consumption for key processing requirements.

**Table 14.1 - Processing Facilities Consumables**

| Parameter | Typical Range |
| --- | --- |
| Concentrator Energy (kWh per metric ton ore) | 20 to 25 |
| Hydrometallurgical Energy (kWh per pound of copper) | 1.0 to 2.0 |
| Mill Makeup Water (cubic meter of water per metric ton ore) | 0.3 to 0.4 |
| Hydrometallurgical Makeup Water (cubic meter of water per metric ton ore) | 0.2 to 0.3 |
| Process Materials |  |
| Liners and Wear Parts (kg of steel per metric ton ore) | 0.1 to 0.2 |
| Balls (kg of steel per metric ton ore) | 0.5 to 0.7 |
| Primary Collector (g of collector per kg copper) | 3 to 7 |
| Lime (kg of lime per metric ton ore) | 1 to 3 |
| Acid (kg of acid per metric ton ore) | 3 to 11 |

Consumable and personnel requirements for the processing facilities are expected to be near current levels in the near-term with variation dependent on production levels in the various unit operations. As of December 31, 2022, the concentrating operations have 1,150 employees and the hydrometallurgical operations have 229 employees. FCX believes contractors are available as needed.

## 15 SITE INFRASTRUCTURE

The site infrastructure at the Cerro Verde mine has been established over the history of the project and supports the current operations. The current major mine infrastructure includes waste rock storage facilities, ROM leach pads, crushed leach pads and stacking systems, temporary stockpiles, TSFs, power and electrical systems, water usage systems, various on-site warehouses and maintenance shops including large-scale mine truck shops, and offices required for administration, engineering, maintenance, and other related mine and processing operations. The communication system at site includes internet and telephone access connected by hard-wire, fiberoptic, and mobile networks. Access to the property is discussed further in Section 4 of this TRS. The site infrastructure is shown in Figure 15.1.

### 15.1 Waste Rock Storage Facilities

The Cerro Verde mine LOM plan considers placing mined waste material in the waste rock storage facilities. FCX believes there is sufficient storage capacity to handle the waste deliveries as scheduled in the LOM plan.

as of December 31, 2022

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

## 15.2 Leach Pads and Stockpiles

The Cerro Verde mine utilizes stockpiles including ROM and crushed leach pads. Mined material is routed directly to the ROM leach pads whereas the crushed leach pad receives mined material that has been reduced in size through a primary crushing stage. The LOM plan includes leach placements concluding in 2044 with the leach pads continuing to be leached through 2046 when the SX/EW plant is expected to conclude operations. Additional leach pad stockpile capacity is required in the LOM plan. A placeholder of estimated costs for the additional capacity is included in the financial analysis.

The mine also has temporary mill stockpiles. Mined material is directed to these stockpiles to be rehandled and processed through the concentrators later in the LOM plan. FCX believes the mill stockpiles have sufficient capacity for the planned deliveries in the LOM plan.

Leach pads, stockpiles, and waste rock storage facilities are surveyed regularly, and daily production records are used to track the mine deliveries.

## 15.3 Tailings Storage Facilities

There are two TSFs at the Cerro Verde mine: the Enlozada and Linga dams. The Enlozada dam receives flotation tailings from the C1 concentrator while Linga receives tailings from C2. The flotation tailings are thickened and pumped to the TSFs where they are deposited, and water is recycled back to the mill.

The TSFs, as currently designed, lack sufficient storage capacity for the entire planned mineral reserves estimate in the LOM plan. However, FCX and the Cerro Verde mine anticipate having sufficient tailings storage available as required in the LOM plan since the current storage capacity is sufficient until 2035 at planned rates, and options to increase capacity have been identified in potential expansions of the currently designed TSFs and alternate locations for additional TSFs. A placeholder of estimated costs for the additional capacity is included in the LOM plan financial analysis.

## 15.4 Power and Electrical

The Cerro Verde mine's electrical power is currently sourced under long-term contracts with ElectroPerú S.A. and Engie Energía Peru S.A. Two 220 kV and one 138 kV transmission lines from Socabaya substation and two 220 kV transmission lines from San Jose substation supply the main power feed to the property.

## 15.5 Water Usage

The Cerro Verde mine's water is supplied by a combination of sources, including the Río Chili and treated wastewater from the city of Arequipa. Water from the Río Chili is treated to remove solids but is not suitable for human consumption. The water feeding the concentrators passes through water treatment plants (the local Peruvian Degremont plant or the on-site WWTP). A small portion of the fresh water supply is treated for domestic use in washrooms, change-house facilities, and emergency wash stations. The treatment plants are skid-mounted, self-contained units using reverse osmosis technology to produce domestic water. Drinking water is provided as bottled water. A portion of the fresh water pumped from the Río Chili discharges into the fresh/firewater tanks. Processing facilities operate using a combination of fresh, treated, and reclaimed water from the in-pit dewatering system and existing TSFs.

# **15.6 Product Handling**

The copper concentrate is delivered to the Port of Matarani, approximately 100 kilometers southwest of the mine site, in sealed containers using a fleet of dedicated truck-trailer road vehicles connecting with railway haulage. The molybdenum concentrate is shipped by truck to either the port of Callao or Matarani in tote bags. At the port, the copper concentrates are loaded onto ocean vessels where it is sold to metal smelting companies in Asia and Europe. Perurail manages the transport of the copper concentrates while the port facilities are operated by Terminal Internacional del Sur. The existing concentrate storage facility at Matarani is adequate to handle the concentrate volumes from Cerro Verde and the other operating mines utilizing the facilities. Copper cathode produced from the leaching operations is sold directly to customers in Peru and Europe.

# **15.7 Logistics, Supplies, and Site Administration**

The operation is integrated between mining and processing facilities and has common management and services, as well as a logistics network that includes warehouses, vehicles, and personnel required to distribute and store the large quantity of supplies used by the operation and its workforce. Bus service is provided to the mine and workplaces. Warehouses are maintained at various locations throughout the site.

Supporting infrastructure at the mine and in Arequipa has been built, improved, and expanded over the life of the project including administration offices, training, recreational, and health service facilities.

# **16 MARKET STUDIES**

The Cerro Verde mine produces copper concentrate and cathode products, with silver in the concentrate. A molybdenum concentrate is also produced.

# **16.1 Market for Mine Products**

Copper is an internationally traded commodity, and its prices are determined by the major metal exchanges. Prices on these exchanges generally reflect the worldwide balance of copper supply and demand and can be volatile and cyclical. In general, demand for copper reflects the rate of underlying world economic growth, particularly in industrial production and construction. FCX believes copper will continue to be essential in these basic uses as well as contribute significantly to new technologies for clean energy, to advance communications, and to enhance public health.

Molybdenum is a key alloying element in steel and the raw material for several chemical-grade products used in catalysts, lubrication, smoke suppression, corrosion inhibition, and pigmentation. Molybdenum chemicals are used to produce high-purity molybdenum metal used in electronics such as flat-panel displays and in super alloys used in aerospace. Reference prices for molybdenum are available in several publications including Platts Metals Daily, CRU Prices Service, and Fastmarkets Metals Bulletin.

Silver is used for jewelry, coinage, and bullion as well as various industrial and electronic applications. Silver can be readily sold on numerous markets throughout the world. Benchmark prices are generally based on London Bullion Market Association quotations.

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

FCX owns smelting, refining, and product conversion facilities for copper and molybdenum products, operated as separate business segments. Sales between FCX's business segments are based on terms similar to arms-length transactions with third-parties at the time of the sale.

The Cerro Verde mine sells its copper concentrate at market rates to major copper smelters worldwide, as well as to major trading companies. The copper cathode production is sold to third-party consumers domestically and merchant traders worldwide.

The mine's molybdenum concentrate is processed through FCX's wholly owned roaster operations at Fort Madison in Iowa, Sierrita mine in Arizona, and Rotterdam in the Netherlands, and a portion through the concentrate leach process at FCX's Bagdad mine in Arizona. The resultant molybdenum products from the Rotterdam plant supply the chemical and steel industries in Europe while the molybdenum products from the U.S. plants supply the industries in the U.S. and Asia. Climax Molybdenum Company, FCX's wholly owned subsidiary, administers the molybdenum business segment.

Most of the copper and molybdenum products resulting from the Cerro Verde mine are sold to customers with whom FCX has built and maintained long-term relationships. The majority of the sales agreements are negotiated annually and are relatively standardized. The underlying copper price is determined by, and fluctuates with, the commodity exchange price while the treatment and refining charges and premiums are negotiated annually based on market conditions. The underlying molybdenum price is determined by published Platts Metals Daily index reference pricing, which is determined by globally reported spot transaction reporting.

## 16.2 Commodity Price Assumptions and Contracts

Long-term metal prices reported are used to demonstrate the economic viability of the mineral reserves and should not be construed as a prediction of future commodity prices. Assumed prices for mineral reserve estimation are:

- $12 per pound for molybdenum.

All contracts currently necessary for supplies and services to maintain the Cerro Verde mine's facilities and production are in place and are anticipated to be renewed or replaced within timeframes and conditions of common industry practices.

FCX and the QPs believe that the marketing and metal price assumptions for metal products are suitable to support the financial analysis of the mineral reserve evaluation. Further information regarding the sale and marketing of the mine's metal products are discussed in FCX's Annual Report on Form 10-K for the year ended December 31, 2022.

## 17 ENVIRONMENTAL STUDIES, PERMITTING, AND SOCIAL IMPACT

The Cerro Verde mine adheres to FCX's environmental and sustainability programs, including policies and management systems regarding environmental, permitting, and community issues. Cerro Verde has implemented an Environmental Management System that is certified to the internationally recognized ISO-14001:2015 standard. FCX's programs are based on policies and systems that align with the International Council on

as of December 31, 2022

64

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

Mining and Metals Sustainable Development Framework and the Copper Mark. FCX routinely evaluates implementation of these policies through internal and external independent assessments and publicly reports on its performance.

Further discussion regarding environmental and social or community impacts is available in the latest FCX Annual Report on Sustainability.

### **17.1 Environmental Considerations**

Environmental monitoring is ongoing at the Cerro Verde mine and will continue over the life of the operations and beyond through closure. The Cerro Verde mine has received multiple ESIS regulatory approvals from the local and national agencies for the construction, operation, and closure of the mine. Many of these regulatory approvals had public participation components. Several of these authorizations required that the Cerro Verde mine conduct environmental and social baselines and impact studies for environmental resources including, but not limited to, air quality, surface and groundwater quality, landscape, soil, climate, traffic, biodiversity, and cultural resources. The Cerro Verde mine continues to monitor these baselines and impact studies regularly at compliance points and report to required agencies.

In December 2012, the MINEM approved the initial ESIS of the CVPUE. The first modification of the CVPUE ESIS was approved by the authorities in 2016. In 2018, as a result of the average capacity increase of the C2 concentrator, SMCV obtained approval of the Beneficiation Plant for processing 548,500 metric tons of ore per day through all processes.

### **17.2 Permitting**

FCX and the Cerro Verde mine staff believe that all major permits and approvals are in place to support operations at the Cerro Verde mine; however, additional permits will likely be necessary in the future. Where permits have specific terms, renewal applications are made to the relevant regulatory authority as required, prior to the end of the permit term.

Any major mining project in Peru requires preparation of an ESIS, including the construction, operation, and closure stages, completed by a third-party consultant, which is submitted to the regulatory agency. An update to the ESIS is required 5 years after its approval. After the ESIS is approved, a comprehensive closure plan including closure cost estimates and financial guarantee schedule is submitted for approval to meet the applicable Peruvian laws and regulations.

Based on the LOM plan, additional permits will likely be necessary in the future for continued operation of the Cerro Verde mine, including a modification of the ESIS and obtaining approval for modified leach pad configurations, increased tailings storage capacity, and corresponding water supply. The Cerro Verde mine will need to submit the Second Modification of the ESIS prior to reaching current tailings storage capacity, which is sufficient until 2035 at planned rates in the LOM plan. Closure strategies will be developed for these proposed facilities as part of the permitting process.

### **17.3 Waste and Tailings Storage, Monitoring, and Water Management**

The Cerro Verde mine has developed and continues to implement detailed, comprehensive mine waste and tailings management programs to meet the applicable Peruvian waste regulations and FCX environmental management practices. These

as of December 31, 2022

65

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

programs incorporate commitments included in the ESIS and the Engineer of Record designs, for the specific cases of TSFs and certain leach pad stockpiles. The site also follows FCX's Tailings Management Policy.

#### **17.4 Mine Closure Plans**

MINEM of Peru governs facility closure under the country's Mine Closure Law and requires preparation of a closure and post closure plan, including development of cost estimates and financial assurance for permitted facilities such as TSFs, leach pad stockpiles, and other mine facilities. The Cerro Verde mine closure strategy and mine reclamation plan, developed by third-parties, considers long-term physical and chemical stability and implementation of feasible post mining land uses for the site following the end of mine operations. The closure strategy and reclamation plan details tasks to be performed at closure and the post-closure phase of the mine's life cycle. The Closure Law requires updates to the closure plan and cost estimates every 5 years and these updates are submitted for approval to the Peruvian regulatory authorities. The current closure plan and cost estimates for the CVPUE were submitted to the Peru regulatory authorities in 2016 and approved in February 2018.

The closure strategy incorporates various approaches including, but not limited to, in-place closure of TSFs and leach pad stockpiles, demolition of processing facilities, and post closure monitoring and maintenance of closed facilities and points of compliance wells. Closure of TSFs includes regrading tailings and installing cover systems that manage water through evaporation. Water management systems are intended to stabilize closed facilities, minimize erosion, and protect water resources.

The total closure cost estimate in the LOM plan is approximately $0.5 billion based on a cash flow schedule for the implementation of closure and post closure tasks. The Cerro Verde mine has complied with the annual renewal of the financial guarantees corresponding to the closure plan.

#### **17.5 Local Stakeholder Considerations and Agreements**

As part of the ongoing permitting and compliance obligations with the regional and national agency authorizations, and as part of the mine's commitment to local stakeholder engagement, the Cerro Verde mine is dedicated to local community and social matters. The Cerro Verde mine seeks to conduct its activities in a transparent manner that promotes proactive and open relationships with the local community, government, and other stakeholders to maximize the positive impacts of its operations and mitigate potential adverse impacts throughout the LOM plan.

The Cerro Verde ESIS includes information on community and social matters, such as a social baseline, potential impacts to communities within the direct area of influence, and community development projects that will be implemented based on feedback received from external stakeholders.

The Cerro Verde mine seeks to provide opportunities to support economic development by purchasing local goods and services, according to its requirements and technical specifications.

Based on the objectives pursued in the strategic development program proposed in the CVPUE ESIS, the Cerro Verde mine complies with regional and local hiring requirements. The Cerro Verde mine operates in the Arequipa province with a large portion of mine

as of December 31, 2022

66

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

employees and contractors from the local and regional labor force. Most of the workforce at the Cerro Verde mine is from Peru.

### 17.6 Comment on Environmental Compliance, Permitting, and Local Engagement

In the QP's opinion, the Cerro Verde mine has adequate plans and programs in place, is in good standing with Peruvian environmental regulatory authorities, and no current conditions related to environmental compliance, permitting, and local engagement represent a material risk to continued operations. The Cerro Verde mine staff have a high level of understanding of the requirements of environmental compliance, permitting, and local stakeholders in order to facilitate the development of the mineral reserve and mineral resource estimates. The periodic inspections by governmental agencies, FCX corporate staff, third-party reviews, and regular reporting confirm this understanding.

## 18 CAPITAL AND OPERATING COSTS

The capital and operating costs are estimated by the property's operations, engineering, management, and accounting personnel in consultation with FCX corporate staff, as appropriate. The cost estimates are applicable to the planned production, mine schedule, and equipment requirements for the LOM plan. The capital costs are summarized in Table 18.1.

**Table 18.1 - Sustaining Capital Costs**

|  | $ billions |
| --- | --- |
| Mine | $1.6 |
| Concentrator | 1.1 |
| Supporting Infrastructure and Environmental | 2.5 |
| Total Capital Expenditures | $5.2 |

Estimates are derived from current costs and adjusted to the reserve price environment. The estimates are not adjusted for escalation or exchange rate fluctuations. Actual realized costs are reviewed periodically, and estimates are refined as required.

Capital costs are primarily sustaining projects consisting of mine equipment replacements and planned site infrastructure projects, most notably to increase TSF and leach pad capacities over the production of the scheduled reserves. Capital cost estimates are derived from current capital costs based on extensive experience gained from many years of operating the property and do not include future inflation. FCX and the Cerro Verde mine staff review actual costs periodically and refine cost estimates as appropriate.

The operating costs for the LOM plan are summarized in Table 18.2.

as of December 31, 2022

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

**Table 18.2 - Operating Costs**

|  | $ billions |

| Processing | 25.4 |
| Balance | 5.4 |
| Total site cash operating costs | 51.3 |
| Freight | 4.3 |
| Treatment charges | 7.9 |
| Peruvian mining royalty tax | 0.3 |
| By-product credits | (9.2) |
| Total net cash costs | $54.6 |
| Unit net cash cost ($ per pound of copper) | $1.95 |

Estimates are derived from current costs and adjusted to the reserve price environment. The estimates are not adjusted for escalation or exchange rate fluctuations. Actual realized costs are reviewed periodically, and estimates are refined as required.

The operating cost estimates are derived from current operating costs and practices based on extensive experience gained from many years of operating the property and do not include future inflation. The operating cost estimates reflect certain pricing assumptions, primarily for energy and foreign exchange rates, that are reflective of the copper market environment ($3.00 per pound for copper price) at which the reserve plan has been prepared. As the property has a long operating history, FCX believes that the accuracy of the cost estimates is better than the minimum of approximately +/- 25 percent required for a pre-feasibility study level of mineral reserves as per S-K1300, and the level of risk in the cost forecasting is low. FCX and the Cerro Verde mine staff review actual costs periodically and refine cost estimates as appropriate.

The LOM plan summary in this TRS is developed to support the economic viability of the mineral reserves. The latest guidance regarding updated operational forecast cost estimates is available in FCX's Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC.

## 19 ECONOMIC ANALYSIS

The LOM plan includes comprehensive operational drivers (mine and corresponding processing plans, metal production schedules, and corresponding equipment plans) and financial estimates (revenues, capital costs, operating costs, downstream processing, freight, taxes, and royalties, etc.) to produce the reserves over the life of the property. The LOM plan is an operational and financial model that also forecasts annual cash flows of the production schedule of the reserves for the life of the property under the assumed pricing and cost assumptions. The LOM plan is used for economic analyses, sensitivity testing, and mine development evaluations.

The financial forecast incorporates revenues and operating costs for all produced metals, processing streams, and overall site management for the life of the property. The economic analysis summary in Table 19.1 includes the material drivers of the economic value for the property and includes the net present value (NPV) of the unleveraged after-tax free cash flows as the key metric for the economic value of the property's reserve plan

as of December 31, 2022

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Cerro Verde Mine, Arequipa, Peru

under these pricing and cost assumptions. This analysis does not include economic measures such as internal rate of return or payback period for capital since these measures are not applicable (and are not calculable) for an on-going operation that does not have a significant upfront capital investment to be recovered.

| Peruvian Mining Taxes (% of operating income) | 6.2 a |
| Corporate Tax Rate (%) | 32 b |
| Exchange rate (Peruvian Nuevo Sol/$) | 3.15 |
| Net present value @ 8% ($ billions) | $6.4 |
| Internal rate of return (%) | NA c |
| Payback (years) | NA c |

a. Peruvian mining taxes include Peruvian mining royalty tax and special mining tax.

b. Tax rate reduced to 29.5% after 2028, when the tax stability agreement expires.

c. Not Applicable (NA) as the property is an on-going operation with no significant negative initial cashflow/initial investment to be recovered.

The key drivers of the economic value of the property include the copper market price, copper grades and recoveries, and costs. Depending on the changes in these key drivers, FCX can adjust operating plans (in the near-term as well as the long-term, as appropriate) to minimize negative impacts to the overall economic value of the property.

Table 19.2 summarizes the economic impact of changes to these key drivers on the property's NPV (as included in Table 19.1). The sensitivities are estimates for the changes in each key drivers' effect on the base plan summarized for the production of the mineral reserves over the life of the property.

**Table 19.2 - Sensitivity Analysis**

| Sensitivity Analysis ($ billions) | Incremental Impact to NPV |  |
| --- | --- | --- |
|  | + 5% Change | - 5% Change |
| Copper price | $1.03 | $(1.03) |
| Copper grade/recovery | 0.90 | (0.91) |
| Capital cost | (0.13) | 0.13 |
| Operating cost | (0.63) | 0.62 |
| Discount rate | (0.23) | 0.24 |

Sensitivity analysis does not reflect changes in mine plans or costs with changes in above items.

The after-tax NPV of the LOM plan is most sensitive to copper price, followed by grades and recovery, and then operating costs. The sensitivity analysis does not reflect changes in mine plans or costs with changes in the reported driver. Sustained periods in these economic scenarios would warrant a re-evaluation of the LOM plan assumptions, mine plan development, and reported mineral reserves.

Table 19.3 summarizes the LOM plan including the annual metal production volumes, mine plan schedule, capital and operating cost estimates, unit net cash costs, and unleveraged after-tax free cash flows over the life of the property. Free cash flow is the operating cash flow less the capital costs and is a key metric to demonstrate the cash that the property is projected to generate from its operations after capital investments for the reserve production plan at assumed pricing and cost assumptions. The property's ability to create value from the reserves is determined by its ability to generate positive free cash flow. The summary demonstrates the favorable free cash flow generated from the property's LOM plan under the assumptions. This economic analysis supports the economic viability of the mineral reserves statement.

Summary of annual cash flow forecast based on annual production schedule for the life of the property.

NOTE: The purpose of the presented figures is to demonstrate the economic viability of the mineral reserves. Given the long-lived nature of the reserves, and inherent variability in the timing of capital expenditures and annual mine planning processes, the annual cash flows may vary in subsequent disclosures. Investors are cautioned that the above is based upon certain assumptions which may differ from FCX's long-term outlook or actual financial results, including, but not limited to, metal prices, escalation assumptions, and other technical inputs. Significant variation of metal prices, costs, and other key assumptions may require modifications to mine plans, models, and prospects.

# **21 OTHER RELEVANT DATA AND INFORMATION**

There have been news articles identifying the mining industry as a potential area for review for increased participation of Peruvian state revenues potentially through increased taxes, royalties, or other such programs. The mineral reserve and resource estimates in this TRS use the assumptions as previously stated; however, increased taxation would have a direct impact on the cash flows of the property. Any enacted legislation would be incorporated into future mineral reserve and resource estimates.

Political uncertainty has created potential instability in the regulatory environment in Peru. There have been widespread and sometimes violent political protests, including attacks on civil infrastructure and businesses, which have resulted in delays in the transport of supplies, products, and people at the Cerro Verde mine. Although the impact on mine supplies has been limited and the Cerro Verde mine continues to operate safely, the situation in Peru remains uncertain, and there is a risk that the protests could negatively impact operations. Any sustained impacts to operations would be incorporated into future mineral reserve and resource estimates.

In the opinion of the QPs, there is no additional information necessary for the mineral reserve and mineral resource estimates in this TRS. Further discussion regarding operational risks, health and safety programs, and other business aspects of the mine are available in FCX's Annual Report on Form 10-K for the year ended December 31, 2022.

# **22 INTERPRETATION AND CONCLUSIONS**

Estimates of mineral reserves and mineral resources are prepared by and are the responsibility of FCX employees. All relevant geologic, engineering, economic, metallurgical, and other data is prepared according to FCX developed procedures and guidelines based on accepted industry practices. FCX maintains a process of verifying and documenting the mineral reserve and mineral resource estimates, information for which are located at the mine site and FCX corporate offices. FCX conducts ongoing studies of its ore bodies to optimize economic value and to manage risk.

FCX and the QPs believe that the geologic interpretation and modeling of exploration data, economic analysis, mine design and sequencing, process scheduling, and operating and capital cost estimation have been developed using accepted industry practices and that the stated mineral reserves and mineral resources comply with SEC regulations. Periodic reviews by third-party consultants confirm these conclusions.

The Cerro Verde mine is a large-scale producing mining property that has been operated by FCX and its predecessors for many years. Mineral reserve and mineral resource estimates consider technical, economic, environmental, and regulatory parameters containing inherent risks. Changes in grade and/or metal recovery estimation, realized metal prices, and operating and capital costs have a direct relationship to the cash flow and profitability of the mine. Other aspects such as changes to environmental or regulatory requirements could alter or restrict the operating performance of the mine. Significant differences from the parameters used in this TRS would justify a re-evaluation of the reported mineral reserve and mineral resource estimates. Mine site administration and FCX dedicate significant resources to managing these risks.

Technical Report Summary for
Grasberg minerals district, Central Papua, Indonesia

# 1 EXECUTIVE SUMMARY

This Technical Report Summary (TRS) is prepared by Qualified Persons (QPs) for Freeport-McMoRan Inc. (FCX), a leading international mining company with headquarters located in Phoenix, Arizona, United States (U.S.). The purpose of this TRS is to report mineral reserve and mineral resource estimates at the Grasberg minerals district using estimation parameters as of December 31, 2022.

# 1.1 Property Description, Current Status, and Ownership

The Grasberg minerals district is a copper, gold, and silver porphyry skarn deposit located in the remote highlands of the Sudirman Mountain Range in the province of Central Papua, Indonesia, on the western half of the island of New Guinea. The Grasberg minerals district includes the following operating underground mines: Grasberg Block Cave (GBC), Deep Mill Level Zone (DMLZ), and Big Gossan (BG). The Grasberg minerals district also includes Kucing Liar (KL), which began development in 2021. The Grasberg open-pit (GRS_OP) ceased production at the end of 2019, and the Deep Ore Zone (DOZ) ceased production at the end of 2021.

The mines operate 365 days per year on a 24 hour per day schedule. Mining and ore processing operations are currently in production and the Grasberg minerals district is considered a production stage property.

PT Freeport Indonesia (PT-FI) is a limited liability company, organized under the laws of the Republic of Indonesia. PT-FI operates the mines in the Grasberg minerals district. On December 21, 2018, FCX completed the transaction with the Indonesia government regarding PT-FI's long-term mining rights and share ownership. Following the transaction, FCX has a 48.76 percent share ownership in PT-FI and the remaining 51.24 percent share ownership is collectively held by PT Indonesia Asahan Aluminum (Persero) (PT Inalum, also known as MIND ID), an Indonesia state-owned enterprise, and PT Indonesia Papua Metal Dan Mineral (formerly known as PT Indocopper Investama), which is expected to be owned by MIND ID and the provincial/regional government in Central Papua, Indonesia. The arrangements related to the transaction also provided for FCX and the other pre-transaction PT-FI shareholders to initially retain the economics of the revenue and cost sharing arrangements under the former unincorporated joint venture with Rio Tinto plc (Rio Tinto). As a result, FCX's economic interest in PT-FI approximated 81 percent through 2022. Since January 1, 2023, FCX's economic interest in PT-FI is 48.76 percent (the same as its ownership interest).

Since 1967, PT-FI has been the only operator of exploration and mining activities in the approximately 24,600-acre operating area under a Special Mining Business Permit "Ijin Usaha Pertambangan Khusus" (IUPK). Under the terms of the IUPK, PT-FI has been granted mining rights through 2031, with rights to extend its mining rights through 2041, subject to, among other things, PT-FI's completion of construction of additional domestic smelting capacity totaling 2 million metric tons of concentrate per year by the end of 2023 (subject to force majeure provisions), and fulfilling its defined fiscal obligations to the Indonesia government. In accordance with Indonesia regulations, PT-FI submits a smelter progress report to the Indonesia government for review every six months.

# 1.2 Geology and Mineralization

The ore bodies are located within and around two main igneous intrusions: the Grasberg monzodiorite and Ertsberg diorite. The host rocks of these ore bodies include both

as of December 31, 2022

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Grasberg minerals district, Central Papua, Indonesia

carbonate and clastic rocks that form the ridge crests and upper flanks of the Sudirman Range and the igneous rocks of monzonitic to dioritic composition that intrude them. The igneous-hosted ore bodies (GBC, and portions of the DMLZ) occur as vein stockworks and disseminations of copper sulfides, dominated by chalcopyrite and to a lesser extent bornite. The sedimentary-rock hosted ore bodies (portions of the DMLZ, KL and all of the BG) occur as “magnetite-rich, calcium/magnesian skarn” replacements, whose location and orientation are strongly influenced by major faults and by the chemistry of the carbonate rocks along the margins of the intrusions.

Grasberg minerals district economic copper, gold, and silver mineralization is hosted in porphyries and skarns. The primary sulfide mineralization is chalcopyrite, with lesser bornite, chalcocite, and covellite. Gold concentrations usually occur as inclusions within the copper sulfide minerals, although in some parts of deposits gold can also be strongly associated with pyrite.

### 1.3 Mineral Reserve Estimate

Mineral reserves are summarized from the Life-of-Mine (LOM) plan, which is the compilation of the relevant modifying factors for establishing an operational, economically viable mine plan.

Mineral reserves have been evaluated considering the modifying factors for conversion of measured and indicated resource classes into proven and probable reserves. Inferred resources are considered to be waste in the LOM plan. The details of the relevant modifying factors included in the estimation of mineral reserves are discussed in Sections 10 through 21.

The LOM plan includes the planned production to be extracted from the mine designs.

As a point of reference, the mineral reserve estimate reports the ore inventories from the LOM plan containing copper, gold, and silver metal and reported as commercially recoverable metal.

Table 1.1 summarizes the mineral reserves reported on a 100 percent and pro rata property ownership basis. The mineral reserve estimate is based on commodity prices of $3.00 per pound for copper, $1,500 per ounce for gold, and $20 per ounce for silver.

The mineral reserve estimate has been prepared using industry accepted practice and conforms to the disclosure requirements of the U.S. Securities and Exchange Commission (SEC) under Subpart 1300 of Regulation S-K (S-K1300). Mineral reserve and mineral resource estimates are evaluated annually, providing the opportunity to reassess the assumed conditions. All the technical and economic issues likely to influence the prospect of economic extraction are anticipated to be resolved under the stated assumed conditions.

1.4 Mineral Resource Estimate

Mineral resources are evaluated using the application of technical and economic factors to a geologic resource block model to generate digital surfaces of mining limits, using specialized geologic and mine planning computer software. The resulting surfaces volumetrically identify material as potentially economical, using the assumed parameters. Mineral resources are the resultant contained metal inventories.

The mineral resource estimate is the inventory of material identified as having a reasonable likelihood for economic extraction inside the mineral resource economic mining limit, less the mineral reserve volume, as applicable. The modifying factors are applied to measured, indicated, and inferred resource classifications to evaluate commercially recoverable metal. As a point of reference, the in-situ ore containing copper, gold, and silver metal is inventoried and reported by ore body.

The reported mineral resource estimate in Table 1.2 is exclusive of the reported mineral reserve estimate, on a 100 percent and pro rata property ownership basis. The 2022

Technical Report Summary for
Grasberg minerals district, Central Papua, Indonesia

The mineral resource estimate has been prepared using industry accepted practice and conforms to the disclosure requirements of S-K1300. Mineral reserve and mineral resource estimates are evaluated annually, providing the opportunity to reassess the assumed conditions. Although all the technical and economic issues likely to influence the prospect of economic extraction of the estimated mineral resource are anticipated to be resolved under the stated assumed conditions, no assurance can be given that the estimated mineral resource will become proven and probable mineral reserves.

1.5 Capital and Operating Cost Estimates

The capital and operating costs are estimated by the property's operations, engineering, management, and accounting personnel in consultation with FCX corporate staff, as appropriate. The cost estimates are applicable to the planned production, mine schedule, and equipment requirements for the LOM plan. The capital costs are summarized in Table 1.3.

Table 1.3 - Capital Costs

|  | $ billions |
| --- | --- |
| Mine | $7.9 |
| Concentrator | 4.3 |
| Supporting Infrastructure | 2.4 |
| Total Capital Expenditures | $14.5 |

Estimates are derived from current costs and adjusted to the reserve price environment. The estimates are not adjusted for escalation or exchange rate fluctuations. Actual realized costs are reviewed periodically and estimates are refined as required.

Capital costs include development and sustaining projects for the production of the scheduled reserves. Capital cost estimates are derived from current capital costs based on extensive experience gained from many years of operating the property and do not include futures inflation. FCX and the PT-FI mine staff review actual costs periodically and refine cost estimates as appropriate.

The operating costs for the LOM plan are summarized in Table 1.4.

| Unit net cash cost at $1,500 Au price ($ per pound of copper) | $0.59 |
| Unit net cash cost at $1,800 Au price ($ per pound of copper) | $0.28 |

Estimates are derived from current costs and adjusted to the reserve price environment. The estimates are not adjusted for escalation or exchange rate fluctuations. Actual realized costs are reviewed periodically and estimates are refined as required.

The operating cost estimates are derived from current operating costs and practices based on extensive experience gained from many years of operating the property and do not include future inflation.

## 1.6 Permitting Requirements

In the QP's opinion, the Grasberg minerals district has adequate plans and programs in place, is in good standing with Indonesia environmental regulatory authorities, and no current conditions related to environmental compliance, permitting and local engagement represent a material risk to continued operations. The Grasberg minerals district staff has a high level of understanding of the requirements of environmental compliance, permitting, and local stakeholders in order to facilitate the development of the mineral reserve and mineral resource estimates. The periodic inspections by governmental agencies, FCX corporate staff, third-party reviews, and regular reporting confirm this understanding.

Based on the LOM plan, additional permits will likely be necessary in the future, including for river diversion out of the tailings management area at closure as discussed in Section 17. In 2020, PT-FI initiated a new environmental impact analysis (called an Analisis Mengenai Dampak Lingkungan or AMDAL) in preparation for the proposed activities associated with the transition from Grasberg surface to underground operations. PT-FI continues to work with Indonesia's Ministry of Environment and Forestry (MoEF) to complete the approval requirements of the AMDAL, which is currently estimated to be received in 2023. PT-FI has completed the initial regulatory review of technical approvals associated with the current AMDAL filing, and is now undergoing AMDAL Commission review and public consultations.

Technical Report Summary for
Grasberg minerals district, Central Papua, Indonesia

The property is located at latitude 4.08 degrees south and longitude 137.12 degrees east
using the World Geodetic System 84 coordinate system.

### 3.2 Ownership

PT-FI is a limited liability company, organized under the laws of the Republic of Indonesia.
PT-FI operates the mines in the Grasberg minerals district. On December 21, 2018, FCX
completed a transaction with the Indonesia government regarding PT-FI's long-term
mining rights and share ownership. Following the transaction, FCX has a 48.76 percent
share ownership in PT-FI and the remaining 51.24 percent share ownership is collectively
held by MIND ID, an Indonesia state-owned enterprise, and PT Indonesia Papua Metal
Dan Mineral (formerly known as PT Indocopper Investama), which is expected to be
owned by MIND ID and the provincial/regional government in Central Papua, Indonesia.
The arrangements related to the transaction also provide for FCX and the other pre-
transaction PT-FI shareholders to initially retain the economics of the revenue and cost
sharing arrangements under the former unincorporated joint venture with Rio Tinto plc
(Rio Tinto). As a result, FCX's economic interest in PT-FI approximated 81 percent through
2022. Since January 1, 2023, FCX's economic interest in PT-FI is 48.76 percent (the same
as its ownership interest).

### 3.3 Land Tenure

Since 1967, PT-FI has been the only operator of exploration and mining activities in the
approximately 24,600-acre operating area under the IUPK. Figure 3.2 shows a map of the
land claim status.

### 3.4 Mineral Rights and Significant Permitting

The Indonesia government granted PT-FI a new special mining license IUPK replacing its former Contract of Work (COW) with the Government of Indonesia (GOI), enabling PT-FI to conduct operations in the Grasberg minerals district through 2041. Under the terms of

as of December 31, 2022

Technical Report Summary for
Grasberg minerals district, Central Papua, Indonesia

the IUPK, PT-FI has been granted an extension of mining rights through 2031, with rights to extend its mining rights through 2041, subject to, among other things, PT-FI completing the construction of additional domestic smelting capacity in Indonesia and fulfilling its defined fiscal obligations to the Indonesia government. The IUPK, and related documentation, contains legal and fiscal terms legally enforceable through 2041. The IUPK may not be extended through 2041 if PT-FI fails to abide by the terms and conditions of the IUPK and applicable laws and regulations.

In connection with PT-FI's 2018 agreement with the Indonesia government to secure the extension of its long-term mining rights, PT-FI has undertaken construction of additional domestic smelting capacity totaling 2 million metric tons of concentrate per year by the end of 2023 (subject to force majeure provisions). In accordance with Indonesia regulations, PT-FI submits a smelter progress report to the Indonesia government for review every six months.

The IUPK also requires PT-FI to pay duties on concentrate exports of 2.5 percent now that development progress for additional smelting capacity in Indonesia has exceeded 30 percent, which will be eliminated when development progress for additional smelting capacity in Indonesia exceeds 50 percent. In late 2022, PT-FI received approval, based on construction progress achieved, for a reduction in export duties from 5 percent to 2.5 percent.

The Indonesia government regulations address the export of unrefined metals including copper concentrate and anode slimes and other matters related to the mining sector. PT-FI's export license for copper concentrate is valid for one-year periods, subject to review by the Indonesia government every six months, depending on greenfield smelter construction progress.

In March 2022, PT-FI received a one-year extension of its concentrate export license through March 19, 2023. Regulations include a permit to export anode slimes which is necessary for PT Smelting (PT-FI's 39.5-percent-owned copper smelter and refinery located in Gresik, Indonesia) to continue operating PT Smelting's export license for anode slimes expires on November 3, 2023.

### 3.5 Comment on Factors and Risks Affecting Access, Title, and Ability to Perform Work

FCX and PT-FI believe all major permits and approvals are in place to support operations at the Grasberg minerals district. Based on the LOM plan, additional permits will likely be necessary in the future, including for river diversion out of the tailings management area at closure as discussed in Section 17. Such processes to obtain these permits and the associated timelines are understood and similar permits have been granted in the past. FCX and PT-FI have environmental, land, water, and permitting departments that monitor and review all aspects of property ownership or other rights and permit requirements so that they are maintained in good standing and any issues are addressed in a timely manner.

The Grasberg minerals district has a partially unionized workforce and has been subject to various lawsuits and work stoppages over the operating history of the mines. FCX and PT-FI understand the importance of the workforce and work in good faith to resolve conflicts.

As of December 31, 2022, FCX and PT-FI believe the mines' access, payments for titles and rights to the mineral claims, and ability to perform work on the property are all in good

standing. Further, to the extent known to the QPs, there are no significant encumbrances, factors, or risks that may affect the ability to perform work in support of the estimates of mineral reserves and mineral resources.

## **4 ACCESSIBILITY, CLIMATE, PHYSIOGRAPHY, LOCAL RESOURCES, AND INFRASTRUCTURE**

The Grasberg minerals district mining and project support area is located at 4 degrees south latitude in Central Papua, Indonesia and covers a range of environmental and physiographic zones.

### **4.1 Accessibility**

The Grasberg minerals district project area lies within the remote highlands of the Sudirman Mountain Range. Access to the project area is from either the portsite in Amamapare on the Tipeoka River or the international airport in Timika approximately 43 kilometers north of the portsite. An all-weather gravel access road connects the portsite to the site and it is the primary access point for people and materials to enter the operations area. The access road spans from the portsite to the mill site while passing the city of Timika, the PT-FI town of Kuala Kencana, and the PT-FI town of Tembagapura in the Mimika Regency. The mill site is at milepost (MP) 74. A bus service is provided for transporting workers. Helicopters service day-to-day operations. Planes out of Timika are operated by a privatized partner and commercial flights provide routine transportation to and from Jakarta and other Indonesia cities.

### **4.2 Climate**

The climate in the project area can be categorized as a tropical monsoon climate; however, climate conditions are highly variable due to changes in elevation. In general, the lowland and coastal areas exhibit a hot, wet, and humid climate, whereas the highlands have a wet, moderate to cool climate.

Annual rainfall ranges from less than 300 centimeters in the highest elevations to 500 centimeters in Tembagapura. Temperatures at the portsite are warm with a range from 19 to 38 degrees Celsius. Temperatures at the mine site are cool with a range from minus 2 to 22 degrees Celsius. It is typical for part of the project area to be under cloud cover daily.

### **4.3 Physiography**

The terrain between the southern portsite in the lowlands to the northward mining area ranges from mangrove swamp and jungle to extremely rugged mountains. The main PT-FI town of Tembagapura is in a temperate mountain valley at an elevation of roughly 1,900 meters.

The deposits are located approximately 96 kilometers north from the coast among elevations ranging between 2,900 to 4,200 meters above sea level.

### **4.4 Local Resources and Infrastructure**

Infrastructure is in place to support mining operations. Section 15 contains additional detail regarding site infrastructure.

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Grasberg minerals district, Central Papua, Indonesia

The mines maintain company-owned townsites at the operation. The primary accommodations for project workers are in Tembagapura, its suburbs Hidden Valley and Ridge Camp in the highlands and Kuala Kencana in the lowlands. Tembagapura houses many of the workers and management associated with mining and processing operations. North of Tembagapura, Ridge Camp is another on-site major housing facility for the mines along with office buildings, remote control mining and maintenance facilities. Ridge Camp is the primary access point to the underground ore bodies.

Supplies are delivered by truck up the main access road to storage facilities across the operations. PT-FI has sole control of ships to transport fuel, supplies, and general cargo to the project area. PT-FI maintains purchasing offices in Jakarta and Surabaya in Indonesia and in Australia, Singapore, and the U.S.

Water sources for the project are a combination of naturally occurring mountain streams and water derived from our underground operations. FCX and PT-FI believe it has sufficient water resources to support current and future operations.

The Grasberg minerals district is currently powered by an on-site coal-fired power plant, with installed capacity of 198MW, built in 1998. Diesel generators, installed starting in the 1970s through the 1990s, with an installed capacity of 130MW, currently supply peaking and backup electrical power generating capacity. As a result of the changing ore body, energy requirements at the Grasberg minerals district are expected to increase due to ventilation needs and more intensive processing requirements. To support this, PT-FI is constructing a dual-fuel power plant (DFPP) that is expected to be fully commissioned in 2023 to support increased power requirements as underground mining continues to ramp up.

Site operations are adequately staffed with experienced operational, technical, and administrative personnel. FCX and PT-FI believe all necessary supplies are available as needed.

## 5 HISTORY

The Grasberg minerals district hosts two copper-gold-silver rich porphyry and skarn hosted systems.

The Ertsberg/Gunung Bijih (GB) “Ore Mountain” ore body was exposed at surface and mapped by the Colijn Expedition in 1936. GB was rediscovered many years later in 1960 by the Freeport Sulfur Company. In 1967, PT-FI entered into an initial 30-year COW with the GOI to mine the GB ore body. PT-FI drilled the GB in the late 1960s and mined it in the 1970s using open-pit techniques.

Following the GB finding was the discovery of the Gunung Bijih Timur (GBT) “Ore Mountain East” ore body 1 kilometer east of the GB open-pit. GBT was discovered by geologists mapping outcrops in the early 1970s during the evaluation of the GB. Exploration drilling in 1975 showed the potential for GBT and it was mined as a block cave from 1981 to 1994. GBT was the beginning of the upper portion of the Ertsberg East Skarn System (EESS), starting block cave operations in 1981. GBT open-pit was part of the GBT discovery but the GBT block cave was prioritized, and the open-pit portion was moved to resource classification.

Technical Report Summary for^{}[] Grasberg minerals district, Central Papua, Indonesia

The Dom ore body was discovered by geologists mapping outcrops in the early 1970s during the evaluation of the GB. Exploration drilling for Dom occurred from 1976 to 1977. Extensive drilling continued in the mid-1980s showing Dom has both open-pit and block cave potential. The geomechanical studies of rolling rock and slope stability issues related to mining of the Dom identified unacceptable levels of risk to mill Amole Ridge facilities below. In 2007, Dom was moved in the schedule to post-KL mining and reported as a mineral resource.

Discovery of the Intermediate Ore Zone (IOZ) was followed by DOZ situated beneath in the late 1970s. DOZ began mining as an open stope mine in 1989 and was converted to block caving techniques in 2000 and was depleted by the end of 2021.

The Grasberg deposit was discovered in 1988. The size and geology of the ore body allowed for open-pit mining from 1990 to 2019 and subsequent block cave mining beginning in 2019.

Since 1990, additional ore bodies have been discovered and delineated, namely DMLZ, BG, and KL. BG is located on the southwest side of the Ertsberg Diorite and started mining with open stope techniques in 2014. DMLZ is the lowest portion of the EESS deposit and has been mined as a block cave since 2015. KL was discovered southwest of the Grasberg deposit and started development in 2021.

The Grasberg minerals district is a well-developed property currently in operation and all previous exploration and development work has been incorporated where appropriate in the access and operation of the property. Exploration and development work is included in the data described in Sections 6 through 11 of this TRS.

## **6 GEOLOGICAL SETTING, MINERALIZATION, AND DEPOSIT**

### **6.1 Regional Geology**

The Grasberg minerals district lies adjacent to the boundary of the Australian and Indo-Pacific plates as shown in Figure 6.1. The geology of the region relates to the collisional delamination tectonics when the Australian and Indo-Pacific mega plates collided along the Derewo zone, located approximately 35 kilometers north of the Grasberg minerals district. This impact caused the continental plate break-off, folded the Sudirman mountain range and upwelled magma into the Grasberg minerals district. The ascension of magma from the upper mantle and differentiation into a calc-alkaline type of intrusion triggered copper and gold mineralization.

## 6.2 Deposit Geology

The Grasberg minerals district is situated on the crest of the Sudirman Mountain Range at elevations over 2,500 meters with the highest peak, Puncak Jaya at 4,884 meters. Ore deposits in the Grasberg minerals district have economic copper, gold, and silver mineralization in porphyries and skarns. The primary sulfide mineralization is chalcopyrite, with lesser bornite, chalcocite, and covellite. Gold concentrations usually occur as inclusions within the copper sulfide minerals although in some parts of deposits gold can also be strongly associated with pyrite. The Grasberg minerals district geology map is shown in Figure 6.2.

Technical Report Summary for
Grasberg minerals district, Central Papua, Indonesia

There are five major ore bodies all within the center of the Grasberg minerals district:

- Grasberg Intrusive Complex (GIC) includes the GBC and the depleted GRS_OP.
- EESS includes DMLZ and depleted GBT, IOZ, DOZ block caves.
- BG.
- KL (development stage mineral reserve).
- Dom (classified as mineral resource).

The ore bodies are located within and around two main igneous intrusions: the Grasberg monzodiorite and Ertsberg diorite. The host rocks of these ore bodies include both carbonate and clastic rocks that form the ridge crests and upper flanks of the Sudirman Range and the igneous rocks of monzonitic to dioritic composition that intrude them. The igneous-hosted ore bodies (GBC and portions of the DMLZ) occur as vein stockworks and disseminations of copper sulfides, dominated by chalcopyrite and to a lesser extent bornite. The sedimentary-rock hosted ore bodies (portions of the DMLZ, KL and all of the BG) occur as "magnetite-rich, calcium/magnesian skarn" replacements, whose location and orientation are strongly influenced by major faults and by the chemistry of the carbonate rocks along the margins of the intrusions.

6.2.1 Structural Geology

The compressional regime played a fundamental role in the structural geometry of the Grasberg minerals district. The collision of Australian and Pacific plates that occurred approximately 8 million years ago caused folding and uplift in the central range of the Sudirman Mountains causing rock units to shorten, forming the west-northwest by east-southeast oriented syncline/anticline systems including the Yellow Valley Syncline (YVS) with peaks nearly 5,000 meters high. The movement of west-northwest trending left lateral faults paired with the northeast striking faults formed pull-apart structures that facilitated magma emplacement.

Ductile and brittle deformation contributed to folding, reverse-thrust faults and bedding slip faults in the Grasberg minerals district. The reverse fault structures occur parallel to the regional fold trend, some with kilometer-scale offsets followed with later strike-slip left-lateral movement. These regional west-northwest by east-southeast structures are cut in places by northeast-southwest trending strike-slip faults which have left-lateral offsets ranging from a few meters to more rarely a few hundred meters.

Chemically reactive sedimentary host rocks combined with pre-conditioned structural zones, enabled fluid to pass through and minerals to precipitate within. The combination of the magma chemical composition, the magma cupola forcing its way to the surface and the reactivation of structures which hydrofractured surrounding rocks, subsequently formed stock-work veined, porphyry copper and gold ore bodies. The GIC was emplaced in the pull-apart basin generated by the Riedel system of west-northwest by east-southeast striking faults and the northeast-southwest trending Grasberg Fault movements that occurred within the YVS axis. The Ertsberg intrusive complex was emplaced along the opening of west-northwest by east-southeast faults.

6.2.2 Rock Types

The sedimentary rock units of the Grasberg minerals district are classified into the two main groups of formations from oldest to youngest as described below and shown in Figure 6.5:

Technical Report Summary for^{}[] Grasberg minerals district, Central Papua, Indonesia

The northern and central portions of the Grasberg minerals district are dominated by the 1.7 kilometer thick, largely carbonate rocks of the Lower to Middle Cenozoic New Guinea Limestone Group. The Kais formation is the uppermost part of the New Guinea Limestone Group and is a 1.2 kilometer thick fossiliferous limestone. The Kais limestone is underlain by the 30-meters-thick quartz-carbonate sandstone of the Sirga formation, a Grasberg minerals district stratigraphic marker. Below the Sirga formation is the 150-meters-thick, massive-bedded, clean limestone of the Faumai formation. The lowermost New Guinea Limestone Group and Cenozoic unit is the Waripi formation, a 300-meters-thick anhydrite nodule-bearing dolomitic limestone, containing thin but laterally continuous quartz sandstone beds. All New Guinea Limestone Group carbonate formations can host high-grade copper and gold skarn mineralization, but the most susceptible unit is the lower part of the Waripi formation.

The New Guinea Limestone Group is underlain by predominantly siliciclastic rocks of the Cretaceous-Jurassic Kembelangan Group, the upper part of which comprises the Ekmai formation, which has three members. In increasing age, these are the 3 to 5-meters-thick Ekmai shale, the 100-meters-thick Ekmai Limestone (a calcareous mudstone), and the 600-meters-thick Ekmai sandstone. The shale member forms an important marker horizon which contains hornfels within the Grasberg minerals district and is seldom mineralized, even where units above and below have high-grade copper and gold skarn. The Ekmai limestone is altered to skarn and hornfels. The Ekmai sandstone is arkosic in nature. Both units commonly host disseminated to fracture-controlled, ore-grade mineralization where they underlie the larger skarn ore bodies.

There are two main intrusive bodies in the Grasberg minerals district: the GIC and the Ertsberg Diorite.

The GIC is comprised of three major and several subordinate, distinct igneous phases. The Main Grasberg Intrusive (MGI) monzodiorite stock intruded through the center of the early formed dioritic fragmental rocks of the Dalam diatreme. Volcanic pyroclastic and flow-dome rocks of Dalam age outcrop and covered much of the pre-mining surface of the GIC. An erosional window in the south-central portion of the deposit exposed MGI-related quartz stockwork hosted copper and gold mineralization at the surface. The late stage intrusion of the South Kali dykes (monzonites), truncated the ore body and signaled the close of the igneous system. These dykes are post-mineralization and are structurally controlled, tabular units which intrude the complex from a separate stock southeast of the GIC.

All intrusions in the Grasberg minerals district are potassium rich, alkalic intrusions. These rocks are classified as monzodiorites, quartz monzodiorites, monzonites, trachyandesites, and trachydacites. The location, size, and shape of the intrusions in the Grasberg minerals district varies with time. Older intrusions (4 to 5 million years old) such as the South Wanagon Suite and the Utikinogon Suite are small sills, ranging from meters to hundreds of square meters in area, on the south side of the Grasberg minerals district. Intermediate intrusions (3 to 4 million years old) such as the Kay, Idenberg, and Lembah Tembaga stocks are “plug-like” in shape and measure hundreds of square meters in area. The younger intrusions (2.6 to 3.5 million years old) like Grasberg and Ertsberg are large composite intrusions or stocks (kilometer scale) and occur further to the north.

### 6.2.3 Alteration and Mineralization

Mineralization occurred in a short timeframe between 2.5 to 3.5 million years, shortly after the emplacement of the metal-laden associated igneous rocks. All the porphyry and skarn

Technical Report Summary for^{}[] Grasberg minerals district, Central Papua, Indonesia

copper ore bodies in the area contain gold and silver as additional metals. The structurally controlled porphyry systems in the Grasberg minerals district are derived from potassium-rich magmas, monzodioritic to monzonitic in composition. Exoskarn and associated mineralization is mainly present in the New Guinea Limestone Group rocks, particularly within the dolomite of the Waripi formation, but also within the Cretaceous Ekmai limestone and sandstone.

The bulk of the mineralization in the Grasberg minerals district occurs within potassic-altered intrusive rocks or within prograde skarn assemblages. Chalcopyrite is the dominant ore mineral in all ore bodies. Bornite prevalence increases with depth in both the Grasberg porphyry and the Ertsberg skarns, but rarely dominates. Covellite is a common constituent in phyllic-altered (sericite-pyrite) zones. It is the dominant copper-bearing mineral in distal portions of KL and is common in the very local, argillic alteration zones at Grasberg and KL, along with other high sulfidation state sulfides. Supergene chalcocite was a minor constituent of the low-grade Grasberg ores to as much as 300 meters below original topography within the highly permeable, anhydrite-depleted “poker chip” zone. Oxide copper minerals are insignificant in all ore bodies, except for Dom where malachite and chrysocolla are abundant.

In the EESS, approximately 80 percent of gold in the prograde skarn and potassic alteration-hosted ores in the deposits occurs as free inclusions in chalcopyrite, bornite, and digenite; the remainder occurs in pyrite and silicate gangue minerals. In zones with intense phyllic and/or advanced argillic alteration, early formed, gold bearing chalcopyrite is converted to covellite with pyrite and gold is taken up in the pyrite lattice. This is especially the case in the highly altered ores in parts of KL and at the deeper margins of the Grasberg deposit. Gold is typically fine grained and not visible. Silver appears to be contained largely within the crystal lattice of the copper-bearing sulfides.

Lead (as galena), zinc (as sphalerite), and arsenic (as arsenopyrite and enargite) generally occur in low concentrations and limited locations. These accessory sulfide minerals are most common at margins of mineralization (BG and KL) and in distal fault-fracture systems, commonly accompanied by anomalous gold values and generally in areas of elevated pyrite and/or pyrrhotite. Pyrite (and lesser pyrrhotite) is relatively uncommon in the potassic alteration and prograde skarn-hosted ores, but can reach high concentrations in the lower grade phyllic and retrograde skarn alteration zones at ore body margins, such as the Heavy Sulfide Zone at GBC, KL, and on margins of DMLZ and BG. Thermal metamorphism of the carbonate rocks is evident in the occurrence of marble aureoles around all the intrusions in the Grasberg minerals district. Marbleization extends outward from the contact between 50 and 1,000 meters. The inner boundary is commonly sharp, beginning at either the igneous/sedimentary rock contact or at the skarn front. The shale member of the Ekmai formation tends to alter to hornfels outward from the igneous contacts (Leys et al., 2012).

## 7 EXPLORATION

The exploration history at the Grasberg minerals district is extensive, starting in the late 1960s and continuing through today. The data, methods, and historical activities presented in this section document actions that led to the initial and continued development of the Grasberg minerals district but are not intended to convey any discussion or disclosure of a new, material exploration target as defined by S-K1300.

Technical Report Summary for
Grasberg minerals district, Central Papua, Indonesia

The Grasberg minerals district hosts two copper-gold-silver rich porphyry and skarn hosted systems. Using a non-economic cutoff grade of 0.1 percent copper, the Grasberg-related system contains approximately 7.5 billion metric tons grading on average 0.70 percent copper and 0.64 parts per million gold in two main deposits, the Grasberg porphyry system, and the KL skarn. The Ertsberg-related system contains roughly 3.6 billion metric tons grading on average 0.60 percent copper and 0.44 parts per million gold (Leys et al., 2012).

Exploration potential exists below mineral reserves as extensions of current mineralization trend. Current operation of the Grasberg minerals district includes routine drilling programs focusing on delineation of deposits, hydrology, metallurgy, and geomechanical programs.

Major exploration summary:

- GRS_OP (Depleted) - Exploration began in 1988. The Grasberg and Kucing Liar (GRSKL) model contains 5,380 drill holes with 1,945 assayed holes containing 94,974 samples totaling 322,150 meters within the final pit. The average drill hole spacing was less than 50 meters. Currently, there are no drilling activities in the open-pit. The GRS_OP produced over 27 billion pounds of copper and 46 million ounces of gold in the 30-year period from 1990 through 2019.
- GBC - Exploration began in 1996. The GRSKL model contains 5,380 drill holes with 842 assayed holes containing 60,584 samples totaling 180,904 meters within the GBC reserve. The average drill hole spacing is 49 meters within the reserve. Current drilling includes delineation, dewatering, and geomechanical holes.
- DMLZ - Exploration began in 2003. The EESS model contains 5,743 drill holes with 1,301 assayed holes containing 75,999 samples totaling 170,936 meters within the DMLZ reserve. The average drill hole spacing is within the reserve is 52 meters. Current drilling activities include: delineation, dewatering, hydrofracking, and geomechanical holes.
- BG - Exploration began at the end of 1991. The BG model contains 1,281 drill holes with 1,110 assayed holes containing 26,745 samples totaling 74,142 meters within the 1 percent Equivalent Copper Grade (EqCu) mineralized envelope. The average drill hole spacing is 28 meters within the reserve. Current drilling includes infill programs to assist with grade control.
- DOZ (Depleted) - Exploration began in the late 1980s. The EESS model contains 5,743 drill holes with 979 assayed holes containing 45,728 samples totaling 111,036 meters within the 2020 DOZ reserve. The average drill hole spacing is 42 meters within the reserve.
- KL - Exploration began in 1994. The GRSKL model contains 5,380 drill holes with 178 assayed holes containing 11,629 samples totaling 33,881 meters within the KL reserve. The average drill hole spacing is 66 meters within the reserve. Current drilling includes delineation, metallurgy, and geomechanical holes.

## 7.1 Drilling and Sampling Methods

The majority of exploration activity in the Grasberg minerals district was drilled from underground with some historical surface core drilling. All drilling used for geologic modelling at PT-FI has utilized diamond core drilling methods since the initial development of the GB deposit.

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Grasberg minerals district, Central Papua, Indonesia

Current drilling diameters are generally HQ-size diameter (63.5mm) and may reduce to NQ-size (47.6mm) for holes deeper than 600 meters. The drill hole database at PT-FI consists of a variety of drill core sizes ranging from BQ size (36.4mm) to PQ-size (85.0mm). Earlier drill programs often collared NQ holes and reduced to BQ for deeper drilling. Most of the material estimated with BQ diameter drilling has already been mined out.

In the opinion of the QP, the exploration programs completed at PT-FI (drilling, sampling, and logging) are appropriate and up to industry standard. Drill hole intervals are on average 3 meters but can range from 0.5 to 6 meters. Drilling sample quality and core recovery is good over the project area.

## **7.2 Collar / Downhole Surveys**

All drill hole collar locations are measured by the mine survey department and stored in the drill hole database. Downhole surveys are collected using the Reflex Gyro, which is not affected by the local magnetic field.

Historically, downhole surveys used the Acid Tube method and occasionally Sperry Sun surveys, but the highly magnetic terrain rendered this latter technique subject to inaccuracy. During the mid-1990s downhole survey methods transitioned to the more reliable Maxibor survey tool and transitioned to the current method of Reflex Gyro. The earliest drilling programs had only collar surveys with the downhole survey projected in a straight line to the end of hole.

#### 7.4 Sample Quality

To maintain sample quality PT-FI has an established a Chain-of-Custody system. The database houses a reporting program used to track sample location and progress. Documentation is prepared prior to DDH core transportation from the drill rig to an intermediate handling facility where samples are subsequently loaded into secured transport containers for delivery to the centralized core handling facility in Timika. Shipment and arrival of samples is confirmed using Chain-of-Custody paperwork and a web-based confirmation system. The whole system is checked annually by a third-party reviewer.

#### 7.5 Sample Logging

DDH core is logged in two phases: a quick log at the drill rig and a more detailed geologic log at the core handling facility by site personnel. A quick log of majority rock type takes place by the project geologist after the driller stores the core in a box. The whole core is then transported to the centralized core logging facility where a number of tasks are completed including core photos, detailed geologic logging, geomechanical logging, density measurements, magnetic susceptibility recording, and core splitting.

**FREEPORT-McMoRAN**

Technical Report Summary for
Grasberg minerals district, Central Papua, Indonesia

The core is washed and photographed prior to logging. Point load tests are completed on selected whole core from each assay interval with the broken core being returned to the core tray prior to sampling. A whole core specimen (10 to 15 centimeters long) is selected from each sample interval for density determination and is subsequently stored as a skeleton for future reference.

## 7.6 Hydrogeology

PT-FI conducts field testing for hydrogeologic parameter determination used for groundwater modeling. Secondary permeability (mainly fractured rock and structure) is the main control on water movement. The hydrogeology monitoring program includes:

- Surface and underground piezometer monitoring of water table position and pore pressure.
- Measurements of rainfall and water flow in catchments as an indication of groundwater recharge rates from precipitation.
- Sampling for water chemistry analysis.

Data collected is analyzed and used to support groundwater movement interpretation. Rock type, alteration and structure, combined with water level measurements, flow interception during drilling, hydraulic testing using pumping, airlift or gravity drains, water sampling and recharge estimation are used for hydrogeology boundary characterization and interpretation within a conceptual hydrogeologic model. Characterization determines the ability of the hydrologic units to produce flow based upon their hydraulic properties.

Numerical models are constructed to simulate water flow using the geologic features in the conceptual model including regional faults, structure, alteration, karstification, rivers, surface water, along with past and future mining areas. Where hydraulic testing is not possible, a model calibration process for water level and flow is used to give the best estimate of hydraulic properties.

## 7.7 Geomechanical Data

Geomechanical logging is performed at the centralized core logging facility in Timika. All DDH core is systematically and uniformly geomechanically logged and tested unless otherwise instructed. Logging procedures follow industry-standard methods agreed upon between PT-FI and its consultants. Geomechanical logging is carried out as soon as possible after drilling, taking care that the core is disturbed as little as possible. Geomechanical measurements are taken using the following methods:

- Rock Quality Designation (RQD)/Fracture Frequency - measures the fracture spacing/density on which rock mass strength partly depends, with other principal factors being fracture orientation and joint condition logging.
- Point Load - measurements are intended as an index test for the strength classification of rock materials. Measurements are taken at 15-meter intervals while recording failure types, structures, and vein descriptions. The selected sample must have a length at least equal to the core diameter measured along the core axis.
- Televiewer - provides high-resolution oriented images of drill hole wall capturing geomechanical data including: lithology, structure, and fracture stress orientation.

In general, rock mass strength is defined spatially based on the laboratory strength testing and distributions of vein intensities. Rock strengths are determined for intact failure types

(where the sample test breaks only through intact rock) and combined failure types (where the sample fails through both intact rock and structure).

7.8 Comment on Exploration

In the opinion of the QP:

- The exploration programs completed at PT-FI (drilling, sampling, and logging) are appropriate for geologic resource modeling.
- The data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for mineral reserve and mineral resource estimation.
- The geomechanical core testing and hydrogeologic records are appropriate to support mine designs.

8 SAMPLE PREPARATION, ANALYSES, AND SECURITY

8.1 Sampling Techniques and Sample Preparation

DDH core is collected by the core handling crew from the drill rig and taken to Kasuang Yard for transport packing by loading into secured transport containers. Core is given a modified drill hole identification number in Kasuang prior to arrival in Timika. PT-FI personnel use a dedicated core transport truck to deliver core to a facility in Timika for logging, storage, and sample preparation. The arrival of DDH's from Kasuang to the Timika is confirmed using a dispatch system and the modified drill hole identification number is replaced with the original.

The Core Processing Facility in Timika is operated and controlled by PT-FI. The Data Administration team tracks the movement of core samples across the project site. The location of every drill hole sample and its status in the system is reported to PT-FI management.

The logging geologist marks the beginning and end points for each sample interval. Sample intervals are 3 meters, although the geologist may choose a shorter interval if the geology or deposit-specific protocols indicate otherwise.

The core is split longitudinally using conventional splitters. A unique sample number is assigned to each sample and logged into the database. Half of the core is returned to the core box while the other half is bagged for shipment to PT Sucofindo Kuala Kencana (SFKK) laboratory for assays with transfer documentation.

The samples are transferred to the SFKK laboratory, checked in, prepared for assay, and assayed. The assay results are reported, and the PT-FI and SFKK analysis of quality assurance and quality control (QA/QC) are compared and reported.

Exploration holes are stored permanently while hydrology holes and other holes outside the reserve are stored temporarily and discarded after 6 months.

8.2 Assaying Methods

Copper is initially assayed using a 0.2-gram aliquot with 3-acid digest and flame atomic absorption spectroscopy (AAS). If the initial assay is greater than 0.50 percent copper, the

as of December 31, 2022

**FREEPORT-McMoRAN**

Technical Report Summary for
Grasberg minerals district, Central Papua, Indonesia

assay is rerun as an “ore grade” sample. Ore grade samples are a 0.5-gram sample run using the same methods as above. If the initial assay is greater than 2 percent copper, the sample is rerun by titration with a 1.0-gram aliquot.

Gold is fire assayed using a 30-gram aliquot with AAS finish unless the overlimit of plus 15 gram per metric ton is reached, in which case a gravimetric finish is used.

Reject splits are retained for future metallurgical work and for duplicate coarse reject analysis.

### 8.3 Sampling and Assay QA/QC

PT-FI geologists provide assay instructions to the current primary laboratory, SFKK. After assaying, all pulps are returned to the core shed in Timika. Historically, the primary assay laboratory has changed over time. Laboratories are internationally and/or domestically certified as follows:

- SFKK is an external laboratory located in Kuala Kencana. The laboratory is ISO 9001:2015, ISO 17020:2012, ISO 17025:2017 and SMKS PP50:2012 certified.
- PT Geoservices-GeoAssay (GA) is an external laboratory located in Jakarta. GA is ISO 17025:2018 accredited and has a KAN LP-463-IDN certification.
- SGS-Indoassay is an external laboratory located in Jakarta. The laboratory has ISO 17025:2008 and SNI ISO/IEC certifications.
- The Mill 74 laboratory is a company-owned laboratory located in the highlands that supports production sampling and is used for production reconciliation at PT-FI. The assay results are not used in the resource modeling estimation process.

The procedures used by PT-FI and SFKK for QA/QC on core samples are as follows:

- Duplicate assays are inserted on a 1 in 10 basis completed by SFKK as a precision or repeatability check on the assay result with duplicate prepared pulps.
- Duplicate rejects are inserted on a 1 in 25 basis completed by SFKK as a precision or repeatability check on the sample pulp preparation process by re-pulping coarse rejects and submitting for assay. Coarse reject samples are also screen analyzed to confirm the size is 95 percent passing 4 millimeters.
- Standard Certified Reference Materials (CRM) are inserted on a 1 in 15 to 20 basis by PT-FI for assay by SFKK and/or the check labs. CRM values are blind to the laboratory.
- Blanks are inserted on a 1 per batch basis by PT-FI. The blank material is currently made up from barren limestone half core from dewatering drill holes. The purpose of blank insertions is to confirm that there is no contamination between samples due to sample preparation errors at the laboratory.
- QA/QC data is located in the drill hole database. All QA/QC check assays are examined for acceptability using QA/QC tools in the database software. Assays that meet QA/QC requirements are accepted into the database; those that did not are rejected and reruns are ordered.

SFKK maintains internal and independent QA/QC procedures in addition to the PT-FI mandated procedures above.

- Standards are also inserted by SFKK on a 1 in 20 basis as an internal laboratory control.
- Blanks are also inserted by SFKK as an internal control.

as of December 31, 2022

![LOGO]

FREEPORT-McMoRAN

Technical Report Summary for
Grasberg minerals district, Central Papua, Indonesia

- A reagent blank is inserted into the AAS sample stream by SFKK as an internal control.

Secondary laboratory checks are performed as part of the QA/QC procedures. Pulps are sent to a third-party laboratory as check assays on a 1 in 15 basis. The current external secondary check laboratory is Intertek in Jakarta. Historically GA and SGS-Indoassay had been used as secondary labs.

PT-FI analyzes the results of the QA/QC sampling regularly and generates reports to PT-FI management as well as sharing the results during monthly meetings between PT-FI and the SFKK laboratory. In addition, QA/QC performance is independently verified by a third-party consultant annually.

8.4 Bulk Density Measurements

Drill core is skeletonized by retaining 10 to 15 centimeter samples selected every 3 meters. These samples are used for density determinations. Specific gravity (SG) is measured by drying the sample, weighing in air, and weighing while immersed in water. SG is calculated using the formula below:

SG = weight in air / (weight in air - weight in water)
Assumes water has an SG of 1 and surface tension is not a factor.

Weighing crushed rock or highly altered rock is difficult, so only solid core is weighed. A factor is applied to the bulk measurement to compensate for fractured samples and considers RQD, broken, and crushed measurements. QA/QC checks are conducted every 50 meters using the water-air weight method and caliper method after the ends of the samples are cut perpendicular to the core axis with a diamond saw.

8.5 Comment on Sample Preparation, Analyses, and Security

In the QP's opinion, sample preparation, analytical methods, security protocols, and QA/QC performance are adequate and supports the use of these analytical data for mineral reserve and mineral resource estimation.

9 DATA VERIFICATION

9.1 Data Entry and Management

PT-FI has a team dedicated to data administration and QA/QC. The Data Administration team manages the master drill hole database and provides QA/QC services for PT-FI. The database is physically housed on a secure server and is automatically backed up. The database is protected by restricting user access and permissions on both the server and within the program. Permissions are assigned by a designated database administrator.

Pre-configured rules are used to maintain data integrity for all stages of data entry within the program. These rules are incorporated for drill hole planning, collar, downhole surveys, geological and geomechanical logging, sampling, assay results, and QA/QC. The program has importers and data entry objects with built-in validation that can be used to produce reports and graphs to inform the database managers of unusual data. The Data

as of December 31, 2022

36

![LOGO]

**FREEPORT-McMoRAN**

Technical Report Summary for
Grasberg minerals district, Central Papua, Indonesia

Administration team verifies that data in the master database is complete and quality control is performed regularly.

The primary laboratory SFKK utilizes a commercially available Laboratory Information Management System (LIMS) to control, store, and transfer analytical results electronically. Data entry errors are reduced in comparison to past systems because assay results from instrumentation report directly to the LIMS software package.

Annual checks of the database are performed by the PT-FI resource geology team in addition to the Data Administration team at the site. These checks include:

- Identifying new drilling added since prior year and comparing summary statistics to the previous year's database.
- Identifying database values that have changed since prior year and verifying that any changes can be explained and justified. This includes checking the collar, survey, and assay data.

## 9.2 Comment on Data Verification

As confirmation of the mineral reserve and resource process, third-party consultants are hired annually to perform verification studies. This study includes the database, geological models, and estimation verification. The Grasberg minerals district was last reviewed for year-end reporting during 2022. The study confirmed there are no issues in the mineral resource estimation and reporting and complies with mining industry standards.

Starting in November 2009, the consultant developed a Data Acquisition and Maintenance checklist. This checklist incorporates a review of the data acquisition tasks required for the reserve and resource reporting. The verification process is completed by the consultant during the annual technical review.

In summary, data verification has been performed by FCX personnel and external consultants contracted by FCX. Based on reviews of this work, it is the QP's opinion that the drill hole database and other supporting geologic data align with accepted industry practices and are adequate for use in mineral reserve and mineral resource estimation.

## 10 MINERAL PROCESSING AND METALLURGICAL TESTING

Mineral reserves and mineral resources are evaluated to be processed using hydrometallurgy and/or concentrating (mill) operations. The applicable processes and testing are discussed below.

### 10.1 Hydrometallurgical Testing and Recovery

Hydrometallurgical processes are not in use at the Grasberg minerals district.

### 10.2 Concentrating Metallurgical Testing and Recovery

Geometallurgical testwork has been performed at FCX's Technology Center facilities (TCT) laboratory (ISO 9001:2015 certified) in Tucson, Arizona since 2009. Prior to that, testwork was performed by Crescent Technology at their laboratory in Belle Chasse, Louisiana. Additionally, geometallurgical testwork has been completed by SGS Mineral Services (SGS) in Lakefield, Ontario. The QA/QC procedures for the hardness testing

as of December 31, 2022

37

![FSC logo]()

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Grasberg minerals district, Central Papua, Indonesia

include repeats, duplicates, and periodic round robin testing with internal and external laboratories. For flotation testing and associated assays, the main QA/QC methodology is by use of repeats and duplicates.

Geometallurgical testing has been conducted to characterize the response of ore samples to comminution and flotation processes and to develop predictive models to forecast recovery and concentrate grades by ore type. The geometallurgical tests are conducted at the scale of a laboratory bench, or in the case of comminution testing with equipment of a laboratory scale. The testwork includes flotation tests and associated assays, JK Ore Hardness Drop Weight testing, Bond Work Index (BWI) testing, and mineralogical analysis including quantitative evaluation of minerals by scanning electron microscopy, known as QEMScan and x-ray diffraction. Testing has been extended beyond the bench scale to either large-scale batch testing or operating a pilot plant facility to generate additional data required for the design of facilities needed to treat the ore.

Table 10.1 summarizes the current modeled LOM overall recovery. These recoveries are a tonnage-weighted summation of modeled recoveries by ore type for each of the deposits.

**Table 10.1 - Modeled LOM Recovery**

| Ore body | Copper Recovery (%) | Gold Recovery (%) | Silver Recovery (%) | Final Concentrate Grade (%Copper) |
| --- | --- | --- | --- | --- |
| GBC | 87.0 | 67.9 | 75.8 | 25.8 |
| DMLZ | 87.9 | 80.7 | 83.3 | 27.1 |
| BG | 94.8 | 70.3 | 83.2 | 28.9 |
| KL | 84.7 | 61.7 | 58.0 | 24.4 |

Fluorine is present in the ore, with higher levels in DMLZ, GBC, and KL-low pyrite ores, and therefore the mill and dewatering plant operations are managed with the objective to maintain fluorine levels in the copper concentrate shipments to less than 1000 parts per million.

### 10.3 Comment on Mineral Processing and Metallurgical Testing and Recoveries

The comminution and flotation response of GBC, DMLZ, and BG have been characterized and are well understood and spatially representative.

Significant drilling has been undertaken on the KL low pyrite ore body to understand flotation and comminution response on the existing concentrator facilities. Additional drilling is ongoing to further define the KL low pyrite ore body. Flotation testwork on drill hole core samples continued through 2022 at the TCT laboratory, while flotation pilot plant testing was conducted by SGS in Lakefield, Ontario.

Work is ongoing to understand the impact of mill throughput rates to flotation residence time and recovery models as mine deliveries approach and sustain a 240 ktpd rate for the LOM forecast.

In the opinion of the QP, the geometallurgical testwork completed on representative samples is appropriate to establish reasonable processing estimates for the different copper-gold porphyry and skarn style mineralization encountered in the deposits. The mill and dewatering plant processes and associated recovery factors are considered

appropriate to support mineral reserve and mineral resource estimation and mine planning.

## **11 MINERAL RESOURCE ESTIMATE**

Mineral resources are evaluated using the application of technical and economic factors to a geologic resource block model to generate digital surfaces or solids of mining limits, using specialized geologic and mine planning computer software. The resulting surfaces or solids volumetrically identify material as potentially economical, using the assumed parameters. Mineral resources are the resultant contained metal inventories.

### **11.1 Resource Block Model**

Relevant geologic and analytical information is incorporated into a three-dimensional digital representation referred to as a geologic resource block model. Mineral resources at PT-FI are based on block models for each of the following mining areas:

- GRSKL including GBC and the depleted GRS_OP.
- EESS incorporating DMLZ, GBT open-pit, Dom and depleted GBT, IOZ, DOZ block caves.
- BG.

The resource block models for the Grasberg minerals district were updated in August 2022 and contain all drilling results available by mid-July 2022. Each block model is discussed in the following subsections with a focus on major metals.

#### **11.1.1 Compositing Strategy**

PT-FI uses 15-meter length composites starting at the collar for GRSKL and EESS. Several items are composited including metals, SG, and magnetic susceptibility. A minimum recovered length of 4.5-meter intact core within a 15-meter composite is required for the composite to be used for grade estimation. Composites with poor core recovery are rejected during the estimation process. Composites are not split or broken at geologic boundaries.

BG has a smaller selective mining unit and therefore a shorter, 5-meter length composite broken by geologic boundaries is used.

Prior to estimation, composites are flagged by rock type and alteration. Composites are also capped at a maximum value with differing caps for copper, gold, and silver for each estimation domain for each ore body.

#### **11.1.2 Statistical Evaluation**

Industry standard geostatistical approaches are used in addition to ore body knowledge from PT-FI geologists in evaluating the geologic model.

Geostatistical analysis of drill hole data is evaluated using classical statistical parameters (mean, standard deviation, number of samples, etc.). Histograms and cumulative frequency plots are used to conduct detailed analyses of sample population data. Assay and composite statistics are compared for each domain.

as of December 31, 2022

39

FREEPORT-McMoRAN

Technical Report Summary for

Grasberg minerals district, Central Papua, Indonesia

Outlier evaluations are performed using log probability plots as well as visual checks to determine capping levels. In many cases, a second level of outlier restriction is applied during estimation where composite values above a certain “high-yield threshold” cannot influence a block estimate beyond a distance which is smaller than the full distance specified by the search ellipse. Contact plots are used to analyze boundaries between the various domains.

Geologic continuity is determined using correlograms, pair-wise-relative, and/or variogram models. Drill hole data is assessed along multiple orientations for each estimation domain for copper, gold, and silver. The nugget is derived from downhole variogram models. Search ellipse anisotropy ratios in most cases conform directly to the anisotropy ratios of the correlogram/variogram models for the respective estimation domain. As a general rule, the search distances conform to 2/3 of the variogram in mineralized estimation zones.

### 11.1.3 Block Model Setup

The GRSKL and EESS block models have 15 by 15 by 15 meter block sizes, providing adequate resolution for engineering and production. This block size is appropriate for porphyry copper mineralization, drill hole spacing, and block cave mining. The mineralization of the BG ore body is narrow and requires a smaller 5 by 5 by 5 meter block size to accommodate more selective stope mining.

Details of the block model setup are shown in Table 11.1.

11.1.5 Geologic Model Interpretation

The regional geologic model is maintained by the Geologic Data Management group at the PT-FI jobsite and is updated on a quarterly basis. Annual resource model updates require the geologic model that is provided to the resource estimation group includes updated interpretations based on the latest data available.

The three-dimensional model covers the Grasberg minerals district and uses drill hole logs and underground mapping to construct wireframes for the following:

- Stratigraphy.
- Intrusions.
- Alteration.
- Faults.

Geology interpretation is done on cross sections perpendicular to the regional strike and are guided by level-plan contours. Cross section spacing varies depending on the level of detail required for each wireframe.

11.1.6 Grade Estimates

Structural, lithological, and mineralized/unmineralized wireframes are combined to create estimation domains. Cutoffs reflecting mineralization boundaries are low enough to not

as of December 31, 2022

**FREEPORT-McMoRAN**

Technical Report Summary for

interfere with the continuity of the grade distribution at the economic cutoff grade and high enough to demarcate a reasonable limit of potential economic mineralization.

Estimation for copper, gold, and silver are interpolated using Ordinary Kriging (OK) and include a high-yield restriction to manage high-grade outliers in addition to capping. GRSKL additionally uses Locally Varying Anisotropy within the main intrusive units to better capture the “horseshoe-like” geometry of the ore body.

The following are general parameters used for the OK estimation of copper, gold, and silver:

- Minimum of 3 and maximum of 10 composites.
- Maximum of 4 composites per drill hole.
- Search ellipse radius along major directions of continuity reduced to 2/3 of the variogram range.
- High-yield samples ranges are additionally restricted using a smaller search radius, further limiting the influence of high-grade samples.

In general, hard boundaries are used for mineralized/unmineralized domains and between sedimentary and intrusive units. Soft boundaries are used in certain circumstances, such as in BG between the shale/limestone units due to the thin bedding of the shale unit.

A background detection limit grade is assigned for copper, gold, and silver for unestimated blocks. Models are validated using both visual and geostatistical methods.

### 11.1.7 Bulk Density

Bulk density or in-place dry density is estimated based on the measured density values for each drill hole interval. SG is composited to 15 meters for block caves and 5 meters for open stope mines separated by estimation zones and values are then converted to final bulk density. The procedures applied are identical in all Grasberg minerals district deposits. The main steps for the bulk density process are:

- The uncorrected density and bulk density factor are estimated by OK method.
- A factor is developed from geomechanical data which incorporates RQD, percent broken, and percent crushed to approximate the voids ratio in the rock mass.
- The final bulk density for mineral reserve and mineral resource estimation is the reduced density by the correction factor.

### 11.1.8 Mineral Resource Classification

Mineral resources are classified into categories of measured, indicated, and inferred. Each category represents a decreasing level of confidence in the estimation of grade values. Measured, indicated, and inferred blocks are classified according to geological continuity, distance to the closest sample, number of drill holes, and the Kriging variance derived during the estimation of copper grades for each ore body.

- Measured requires a minimum of 2 drill holes contributing data to the estimate, statistically established distance to the nearest composite and Kriging variance below a defined measured threshold.
- Indicated requires a minimum of 2 drill holes contributing data to the estimate, statistically established distance to the nearest composite and Kriging variance below a defined indicated threshold.

as of December 31, 2022

**FREEPORT-McMoRAN**

Technical Report Summary for^{}[] Grasberg minerals district, Central Papua, Indonesia

- Inferred requires only 1 drill hole, beyond indicated distance and a Kriging variance threshold.

Inferred blocks have their grades set for the final reported variables used in the determination of mineral reserve to the analytical detection limit (near zero). Detailed classification parameters are shown in Table 11.2.

### 11.1.9 Model Validation and Performance

The geologic resource model is evaluated by visual inspection, statistical analysis, comparison to previous models and to production data. Block model values and drill hole data are visually examined. The review verifies that areas of high-grade and low-grade blocks and samples align with ore body knowledge. These inspections have shown that block model values compare well with the drill hole composites.

Statistical analyses such as mean, standard deviation, minimum, maximum, and coefficients of variation along with cumulative frequency plots are used to validate the interpolated blocks against drill hole composites, grade-tonnage curves, and reconciliation to production. Block model OK results are compared with the composite data and nearest neighbor estimates. Variable estimations are compared to previous year's estimates. Models are exchanged with other members of the resource group for peer review.

As confirmation of the mineral reserve and mineral resource process, third-party consultants are hired annually to perform verification studies. This study includes the database, geologic models, and estimation verification. The results of the 2022 third-party consultant's evaluation concluded that the methods and procedures used for mineral resource and reserve evaluation are performed in a manner consistent with good engineering and geologic practice.

FCX standards provide that the resource model should be within 10 percent of production for tonnage, grade, and contained or recoverable metal over a 12-month period. The model meets FCX criteria. Reconciliation data is routinely reviewed, and action plans are administered to investigate noted variances.

### 11.1.10 Comment on Geologic Resource Model

In the opinion of the QP:

- The resource model has been completed using accepted industry practices.
- The model is suitable for estimation of mineral reserves and mineral resources.
- The model is adequate to provide reliable inputs to mine planning, geomechanics and metallurgy.
- The PT-FI geology staff has a good understanding of the lithology, structure, alteration, and copper mineral types in the Grasberg minerals district. The understanding of the controls on mineralization are adequate to support estimation of mineral reserves and mineral resources.
- The understanding and interpretation of ore types based on copper-gold mineralogy is a key component to supporting classification of mineral reserves and mineral resources by process method.

## 11.2 Resource Evaluation

Mineral resource estimates are developed by applying technical and economic modifying factors to the geologic block model to identify material with potential for economic extraction. The process of evaluation is iterative, involving an initial draft using the assumptions, understanding the implications of the resulting economical mining limits, and adjusting the assumptions as warranted for subsequent evaluations.

Mineral resource estimates are determined using measured, indicated, and inferred classified materials as viable ore sources during evaluations with the modifying factors.

11.2.1 Economic Assumptions

FCX executive management establishes reasonable long-term metal pricing to be used in determining mineral reserves and mineral resources. These prices are based on reviewing external market projections, historical prices, comparison of peer mining companies' reported price estimates, and internal capital investment guidelines. The long-term sale prices align the company's strategy for evaluating the economic feasibility of the mineral reserves and mineral resources.

The mineral reserves and mineral resources are based on specific volumes of potentially economic, mineralized material in which FCX has the most confidence to produce an acceptable economic result, given a set of evaluation assumptions. As work continues to increase FCX's confidence through drilling, test work, and the evaluation of engineering work and other modifying factors, FCX anticipates conversion of resources to reserves in the future, which may require, among other things, higher metal prices.

In developing the economic assumptions used to determine mineral reserves and mineral resources during early 2022, FCX and its QPs made comparisons of the commodity price assumptions against various periods of historical average prices and current spot prices. Additionally, long-term forward-looking price projections from various sources of third-party market consensus services and financial institution reports covering periods ranging from 2022 to 2035 were reviewed. This information is used as reference for reasonableness of the assumptions. FCX concluded that mineral reserve price assumptions of $3.00 per pound for copper, $1,500 per ounce for gold, and $20 per ounce for silver were reasonable in comparison to the reference points and expected volumes of potentially economic material. FCX also concluded mineral resource price assumptions of $3.50 per pound for copper, $1,500 per ounce for gold, and $20 per ounce for silver were reasonable and aligned with industry-accepted practice to use higher metal prices for the mineral resource estimates than the pricing used for determining mineral reserves.

For copper, London Metal Exchange copper settlement prices over various historical periods were reviewed. For the 10-year period ended December 31, 2022, the price ranged from $1.96 per pound to $4.87 per pound and averaged $3.06 per pound. During 2022, forward-looking prices ranged from $2.70 per pound to $4.08 per pound.

For gold, London PM gold prices over various historical periods were reviewed. For the 10-year period ended December 31, 2022, the price ranged from $1,049 per ounce to $2,067 per ounce and averaged $1,437 per ounce. During 2022, forward-looking prices ranged from $1,172 per ounce to $1,940 per ounce.

For silver, London PM silver prices over various historical periods were reviewed. For the 10-year period ended December 31, 2022, the price ranged from $12.01 per ounce to $32.23 per ounce and averaged $19.20 per ounce. During 2022, forward-looking prices ranged from $14.00 per ounce to $24.79 per ounce.

Unit costs are derived from current operating forecasts benchmarked against historical results and other similar operations. Additional input from appropriate internal FCX departments such as Global Supply Chain, Sales and Marketing, and Finance and Accounting are considered when developing the economic assumptions.

To recognize the relationship between commodity prices and principal consumable cost drivers, FCX scales unit costs to reflect the cost environment associated with the reported metal prices. This is evidenced in the differences in economic assumptions between mineral reserves and mineral resources.

The metal price and cost assumptions are used over the timeframe of the expected life of the mines and reflect steady-state operating conditions in the metal price cost environment. Details of the economic assumptions are outlined in Table 11.3.

### 11.2.2 Processing Recoveries

Processing recoveries are outlined in Section 10.

### 11.2.3 Physical Constraints

The evaluation of the resource is within the IUPK boundary and there are no physical constraints considered.

### 11.2.4 Cutoff Grades

A cutoff grade is used to determine whether material should be mined and if that material should be processed as ore or left unmined.

The mine planning software evaluates the revenue and cost for each block in the block model to determine the value, using the provided assumptions. The following formula demonstrates how the cutoff grades are determined.

$$\text{Internal cutoff grade} = \frac{\text{Sum of [processing costs + general site and sustaining costs]}}{\text{Sum of [payable recoverable metal * (metal price - metal refining and sales costs)]}}$$

A break-even cutoff grade calculation is similar to the internal cutoff grade formula but includes mining costs. Blocks with grades above the break-even cutoff grade generate positive value, while blocks with grades above the internal cutoff grade minimize negative value. The cutoff grades reported for mineral resources reflect the internal cutoff grades based on the software results.

Input parameters are applied to individual deposits and distinct ore types as appropriate. Unique parameters can result in distinct cutoff grades. Cutoff grades are reported in terms of EqCu defining the relative value of all commercially recoverable metals in terms of copper by ore processing methods.

An internal cutoff grade is used as the lower limit for consideration for ore/waste selection when there is incremental ore processing capacity available and the incremental feed can be accessed without any incremental capital input.

In the block caves, a similar situation arises for incremental ore that can be produced from an existing drawpoint. In this case, the assumption is that as long as there are no additional costs associated with maintaining the drawpoint, then lower grade increments can be pulled and processed as long as they fill spare capacity and provide a marginal benefit to the project. For the block caves, it is unreasonable to expect that continued draw from depleted drawpoints can be sustained before repair and redevelopment costs begin to arise. Therefore, overpull of significant incremental tonnages cannot be justified at the internal cutoff beyond the expected life of the drawpoint. Delineation of an incremental

"overpull" resource, above a block cave's planned height of draw must recognize the incremental costs associated with maintaining the draw infrastructure beyond its planned life.

This approach provides realistic economic criteria for defining overpull resources. Overpull resources represent an opportunity to the operation should circumstances allow for its production. As a block cave's production level is abandoned, the overlying portion of the overpull resource is extinguished.

Conceptually the cutoff grade for overpull should be higher than the internal cutoff grade for each mine, but smaller than the breakeven cutoff grade for determining resources outside of already developed mining areas.

- The assumption is that there would be higher mining costs associated with producing ore from these overpulled drawpoints.
- These higher costs would include more extensive drawpoint and panel repair, increased wet muck production, possibly requiring a minimum economic recovery and other factors that result from mining of very high, mature draw columns in an aging production block.

11.2.5 Economic and Technical Assumptions

The economic and technical assumptions used for the generation of potentially economical mining limits for mineral resources are summarized in Table 11.3.

Technical Report Summary for
Grasberg minerals district, Central Papua, Indonesia

Metal prices and other assumptions for mineral reserve and mineral resource evaluations are reviewed at least annually with FCX management. As of December 31, 2022, FCX and its QPs concluded that the assumptions for mineral reserve and mineral resource determinations were reasonable.

### 11.3 Mineral Resource Statement

The mineral resource estimate is the inventory of material identified as having a reasonable likelihood for economic extraction inside the mineral resource economical mining limit, less the mineral reserve volume, as applicable. The modifying factors are applied to measured, indicated, and inferred resource classifications to evaluate commercially recoverable metal. As a point of reference, the in-situ ore containing copper, gold, and silver metal is inventoried and reported by ore body.

The reported mineral resource estimate in Table 11.4 is exclusive of the reported mineral reserve estimate, on a 100 percent and pro rata property ownership basis. The 2022 updated mineral resource estimate is based on commodity prices of $3.50 per pound for copper, $1,500 per ounce for gold, and $20 per ounce for silver.

Technical Report Summary for
Grasberg minerals district, Central Papua, Indonesia

Extraction of the mineral resource may require significant capital investment, specific market conditions, expanded or new processing facilities, additional material storage facilities, changes to mine designs, or other material changes to the current operation.

In the opinion of the QP, risk factors that may materially affect the mineral resource estimate include (but are not limited to):

- Metal price and other economic assumptions.
- Changes in interpretations of continuity and geometry of mineralization zones.
- Changes in parameter assumptions related to the mine design evaluation including geotechnical, mining, processing capabilities, and metallurgical recoveries.
- Changes in assumptions made as to the continued ability to access and operate the site, retain mineral and surface rights and titles, maintain the operation within environmental and other regulatory permits, and social license to operate.

Uncertainty in geological resource modeling is monitored by reconciling model performance against actual production results, as part of the FCX geologic resource model verification process.

#### **11.4 Comment on Mineral Resource Estimate**

The mineral resource estimate has been prepared using industry accepted practice and conforms to the disclosure requirements of S-K1300. Mineral reserve and mineral resource estimates are evaluated annually providing the opportunity to reassess the assumed conditions. Although all the technical and economic issues likely to influence the prospect of economic extraction of the resource are anticipated to be resolved under the stated assumed conditions, no assurance can be given that the estimated mineral resource will become proven and probable mineral reserves.

### **12 MINERAL RESERVE ESTIMATE**

Mineral reserves are summarized from the LOM plan, which is the compilation of the relevant modifying factors for establishing an operational, economically viable mine plan. The LOM plan incorporates:

- Scheduling material movements for ore and waste from designed final mining excavation plans with a set of internal development sequences, based on the results of the resource evaluation process.
- Planned production from scheduled deliveries to processing facilities, considering metallurgical recoveries, and planned processing rates and activities.
- Capital and operating cost estimates for achieving the planned production.
- Assumptions for major commodity prices and other key consumable usage estimates.
- Revenues and cash flow estimates.
- Financial analysis including tax considerations.

Mineral reserves have been evaluated considering the modifying factors for conversion of measured and indicated resource classes into proven and probable reserves. Inferred resources are considered to be waste in the LOM plan. The details of the relevant modifying factors included in the estimation of mineral reserves are discussed in Sections 10 through 21.

The LOM plan includes the planned production to be extracted from the in-situ mine designs.

### **12.1 Cutoff Grade Strategy**

The cutoff grade strategy is a result of the mine plan development, determined by the economic evaluation of the mineral reserves via strategic long-range mine and business planning. Economic cutoff grades are determined from the LOM planning results and can vary based on processing throughput expectations, ore availability, future ore and overburden or waste requirements, and other factors encountered as the mines operate. This approach is consistent with accepted mining industry practice. Cutoff grades reported are the minimum grades expected to be delivered to a processing facility.

### **12.2 Economic and Technical Assumptions**

The economic and technical assumptions used in the generation of economical mining limits for mineral reserves are summarized in Table 12.1. Economic reserve assumptions are developed in the same manner as the resource evaluation described in section 11.2.1.

are within the limits of acceptable engineering error and that the estimated reserves conform to the definitions within S-K1300."

The positive economics of the financial analysis of the LOM plan demonstrate the economic viability of the mineral reserve estimate.

12.4 Comment on Mineral Reserve Estimate

The mineral reserve estimate has been prepared using industry accepted practice and conforms to the disclosure requirements of S-K1300. Mineral reserve and mineral resource estimates are evaluated annually, providing the opportunity to reassess the assumed conditions. All the technical and economic issues likely to influence the prospect of economic extraction are anticipated to be resolved under the stated assumed conditions.

Mineral reserve estimates consider technical, economic, environmental, and regulatory parameters containing inherent risks. Changes in grade and/or metal recovery estimation, realized metal prices, and operating and capital costs have a direct relationship to the cash flow and profitability of the mine. Other aspects such as changes to environmental or regulatory requirements could alter or restrict the operating performance of the mines. Significant differences from the parameters used in this TRS would justify a re-evaluation of the reported mineral reserve and mineral resource estimates. Mine site administration and FCX dedicate significant resources to managing these risks.

13 MINING METHODS

The Grasberg minerals district has a long operational history and mining conditions are well understood by jobsite and FCX corporate staff. All of the currently active operations are underground mines. The mining method for each reserve is as follows:

- GBC: block/panel cave mine.
- DMLZ: block/panel cave mine.
- BG: open stope mine.
- KL: block/panel cave mine.

13.1 Mine Design

Many mine method parameters are applied at PT-FI to prepare mine designs, based on over 40 years of underground production experience. A few generalities exist, such as undercut placement over the production drifts, production level layouts, ore pass locations, chute cutouts, general ventilation requirements, and drain level locations. However, most of the final design involves numerous iterations, with input from operations, in order to best meet operational and cost objectives. Once the final design is approved, minor changes can occur without disruption to the operational development process, as development mining of the infrastructure and main levels is executed several years ahead of placing the initial portion of the ore panels into active production.

Mine designs are developed using specialized mine design computer software.

Technical Report Summary for
Grasberg minerals district, Central Papua, Indonesia

### 13.1.1 Mine Design Parameters

Geomechanical recommendations for each of the operating mines are determined and reviewed by FCX engineers and third-party consultants. These recommendations are based on comprehensive geomechanical testing, studies, and the geomechanical monitoring procedures in the field.

The geomechanical properties of the rock determine the rock parameters for the panel cave design and all other underground facilities. The rock mass response of these properties to the mining process are considered when designing the mining method and setting the reserves at each mine.

### 13.1.2 Geomechanical and Hydrological Modeling

The rock stability of the underground mines is monitored with a variety of geomechanical piezometer instrumentation and sensors. The geomechanical instruments measure the movement in the rock and the measurements are used to monitor and manage any movement and stability concerns. Typical instrumentation includes time-domain reflectometry, open-hole camera monitoring, radar units, scanning units, and seismic monitoring. Groundwater is monitored to check flow and pressure to help manage any safety and stability concerns.

### 13.1.3 Final Mine Design

Using specialized computer software, mine designs are developed with key considerations that include:

- Compliance with the geomechanical recommendations.
- Implementation of geomechanical model data, including general geology, in-situ rock properties, structural data, and mass classification.
- Proper geometric dimensioning for underground structures, such as pillars, stopes, and openings.
- Access for entry and egress.
- Underground roadways design.
- Mechanization and efficiencies, such as matching equipment and fleets.
- Ventilation requirements.
- Dilution considerations.
- Infrastructure and supplies.

Mine designs are reviewed for compliance with key parameters and reasonableness with comparison to historical and current operating practices. Figure 13.1 is a three-dimensional perspective view of the Grasberg minerals district showing the layout and mineral reserve shapes of the mines.

**Figure 13.1 - Perspective View of the Grasberg Minerals District Underground Reserves**

![img-0.jpeg](img-0.jpeg)

During 2022 there were three active underground mining operations in the Grasberg minerals district: GBC (ultimately targeting 135,000 metric tons of ore per day), DMLZ block cave mine (ultimately targeting 80,000 metric tons of ore per day), and BG open stoping operation (targeting 7,000 metric tons of ore per day). The KL ore body is another large caving operation that started development in 2021 and PT-FI anticipates will begin ore production in 2028. At the beginning of 2022, DOZ produced a total of 26,000 metric tons before closure. The GRS_OP was in production from 1990 to 2019. The concentrating plant has a planned peak capacity of approximately 240,000 metric tons of ore per day.

### 13.2 Mine Plan Development

The mine plan is developed based on supplying ore to the processing facilities. The mine production schedule is produced using specialized industry software. The software evaluates the block model and applies various mixing mechanisms such as fines migration, rilling, toppling, and vertical movement of material. The algorithms that control this mixing are proprietary to the software, based on over 30 years of development and standard practice in the industry. Numerous inputs allow customization of the mixing properties and calibration to actual cave performance. With the mixing model created, the software produces a production schedule based on planned production rates, drawpoint opening sequence, estimated draw rates, and other inputs. The production schedule reports the tonnage and grade per time period and is used for the metal forecasting process.

Technical Report Summary for^{}[] Grasberg minerals district, Central Papua, Indonesia

The Grasberg minerals district is one of the largest producing underground operations in the world. No stripping is required as all production is generated from underground mining. Underground mine development is typically between 35 and 40 kilometers of tunneling annually. The BG mine uses an open stoping with paste backfill method and typically emplaces between 600,000 to 700,000 cubic meters of paste per year.

Dilution of the reserve is accounted for by modeling the entry of material into the mixing model from previously caved zones and open-pit failures. The mine plan is scheduled to achieve a total of 240,000 metric tons of ore per day as the different mining operations ramp-up. This is expected to be achieved from four operating mines supplying ore to the mill: GBC, DMLZ, BG and KL.

The mine production rate and expected mine life are illustrated in Figure 13.2.

**Figure 13.2 - Tonnage Per Day by Operating Mine**

### 13.3 Mine Operations

Mine unit operations include drilling, blasting to develop access, undercuts, drawbell development, ore raise development, drawpoint development, cave initiation, as well as loading and hauling. Support equipment is used for maintaining underground access roads, underground crushers, conveyors, and other mine services.

Required underground mining equipment varies by individual operation and includes that equipment required to develop and construct the mines as well as production support. The primary mining fleet consists of a mixed fleet of load-haul-dump loaders with 10-15 metric ton capacity and haul trucks with 55 to 60 metric ton capacity.

The site is in operation with experienced management and sufficient personnel. The mines operate 365 days per year on a 24 hour per day schedule. Operational, technical, and

administrative staff are on-site to support the operation. As of December 31, 2022, the underground mine division has approximately 5,400 employees.

## **14 PROCESSING AND RECOVERY METHODS**

The process facilities operate 365 days per year with exceptions for maintenance. The facilities have a long operating history. FCX and PT-FI anticipate that the site will have adequate energy, water, process materials, and permits to continue operating throughout the LOM.

### **14.1 Concentrator Processing Description**

The concentrator facilities located at MP74 are at an elevation of 2,800 to 2,900 meters above sea level and approximately 110 kilometers from the portsite dewatering and shipping facilities. The concentrators treat primary crushed ore conveyed from underground mines to surface stockpiles at MP74.

The first processing facilities treating Ertsberg pit ores were commissioned in 1973 and have seen incremental capacity enhancements over the years. Ore is processed in the mill, which produces a copper concentrate by flotation. Ore is delivered from the mines to an underground primary crusher where it is crushed and then conveyed to coarse ore mill stockpiles that feed the concentrators. Ore is conveyed from the mill stockpiles to the copper concentrators.

Ore enters the C1/C2 concentrator, where the secondary crushers accept scalped feed and are followed by a tertiary crushing circuit operating in closed circuit with vibrating screens, which provide the initial size reduction. Scalped screen undersize slurry, known as crusher slurry, is fed to hydrocyclones ahead of the C1/C2 ball mill circuit, with the classified fines fraction reporting directly to flotation, bypassing ball milling, and the classified coarse fraction to ball mill feed. A portion of the crusher slurry can also be transferred to the C3/C4 ball mill grinding circuit. Tertiary crusher screen undersize is fed to the High-Pressure Grinding Roll (HPGR). HPGR product is delivered to fine-ore storage bins for ultimate feed to the ball mill circuit. Ball mill discharge slurry is pumped to hydrocyclones where it is classified. The hydrocyclone underflow (coarse fraction) returns to ball mills for further grinding. A slipstream of the hydrocyclone underflow reports to the Knelson gravity circuit to improve coarse gold recovery. The hydrocyclone overflow (fine fraction) reports to rougher flotation for copper and gold recovery. Rougher concentrate advances to regrind mills and cleaner flotation to produce a final concentrate. A slipstream of regrind hydrocyclone underflow reports to a Knelson gravity circuit to improve gold recovery. Knelson concentrate is combined with the final flotation concentrate.

For the C3/C4 concentrator, ore enters the primary grinding circuit, where it is processed through a semi-autogenous grinding (SAG) mill. SAG mill product discharges onto vibrating screens. The screen oversize is conveyed to cone crushers, where pebbles are crushed before being recycled back to the SAG mill feed. An option exists to direct the crushed pebbles to the vibrating screens. The screen undersize is pumped to hydrocyclones where it is classified. The majority of hydrocyclone underflow (coarse fraction) reports to ball mills for further grinding. A slipstream of the hydrocyclone underflow reports to the Knelson gravity circuit to improve coarse gold recovery. The ball mill discharge mixes with Knelson wet screen undersize before being pumped back to the hydrocyclones. The hydrocyclone overflow (fine fraction) reports to rougher flotation for

copper and gold recovery. Rougher concentrate advances to regrind mills and cleaner flotation to produce a final copper and gold concentrate. A slipstream of regrind hydrocyclone underflow reports to a Knelson gravity circuit to improve gold recovery. Knelson concentrate is combined with the final flotation concentrate.

The nominal processing rate used in the LOM plan is provided in Table 14.1.

**Table 14.1 - Summary of Processing Facilities**

| Facility | Purpose / Comments / Capacity |
| --- | --- |
| Concentrators 1 and 2 | Commonly referred to as C1/C2 or the North/South concentrators. Size reduction is achieved with 2 secondary crushers on scalped feed, followed by 8 tertiary crushers in closed circuit with screens, then 2 HPGRs in quaternary crushing duty, followed by 8 ball mills prior to rougher and then cleaner flotation. Combined milling capacity is approximately 65k dmt per day. |
| Concentrator 3 | Commonly referred to as C3 or the SAG1 concentrator. SAG mill in closed circuit with a pebble crusher followed by 2 parallel ball mills for size reduction prior to rougher and cleaner flotation. Nominal C3 SAG milling capacity is approximately 50k dmt per day; however, with SAG milling technology throughput is sensitive to ore hardness and feed size resulting in capacity variations up to +/-30%. |
| Concentrator 4 | Commonly referred to as C4 or the SAG2 concentrator. SAG mill in closed circuit with 2 pebble crushers followed by 4 parallel ball mills for size reduction prior to rougher and cleaner flotation. The C3 and C4 concentrators share a common cleaner circuit located in the C3 concentrator building. Nominal C4 SAG milling capacity is approximately 90k dmt per day; however, with SAG milling technology throughput is sensitive to ore hardness and feed size resulting in capacity variations up to +/-30%. |
| Concentrate Pumphouse and Pipeline | Thickeners, storage tanks, positive displacement pumps and carbon steel slurry pipeline (3x 6' diameter, 1x 5' diameter) to deliver copper concentrate to dewatering plant facilities at portsite. Nominal capacity is approximately 3.6M dmt per year. |
| Dewatering Plant | 3 vacuum and 2 pressure filtration systems to reduce moisture content from 65% solids to less than 9.8% moisture. Sustainable capacity is approximately 2.7M dmt per year with current assets. Short term filtering rates up to an annualized rate of 3.0M dmt per year are possible. |
| Ship Loading | Storage barns, conveyors, loading dock and lightering barge to load copper concentrate to bulk cargo vessels for sale globally. Nominal capacity is approximately 3.0M dmt per year. |

Copper concentrate from all concentrators is thickened before it advances to the pumphouse to be delivered by pipeline to the port facilities. At the portsite, the dewatering plant filters and stores the final product in a concentrate storage building. Copper concentrate is then loaded onto bulk cargo ships for global sale to off-site smelters.

Milled material that does not float to make a copper concentrate is called tailings and has a low-value mineral content. Flotation tailings advance to tailings thickeners where process water is recovered and recycled back to the concentrators. Thickened tailings flow by gravity to the tailings storage facility known as the Modified Ajkwa Deposition Area (ModADA). Limestone is added to the mill feed as needed to maintain the neutral geochemistry of the mill tailings.

Figure 14.1 provides a simplified schematic of the C1 and C2 concentrators. Figure 14.2 provides a simplified schematic of the C3 and C4 concentrators.

Technical Report Summary for^{}[] Grasberg minerals district, Central Papua, Indonesia

The processing facility performance is reviewed regularly, and adjustments are made as necessary to improve performance and reduce costs.

#### 14.2 Processing Requirements

The PT-FI mill has been operating since 1973 and all equipment and processes are proven in an industrial application. FCX believes adequate supplies for energy, water, process materials, and sufficient personnel are currently available to maintain operations and are anticipated throughout the LOM plan. Process materials are provided to the jobsite on an as-needed basis through the FCX and PT-FI global supply chain departments. The actual consumption of key processing supplies varies depending on ore feed and operating conditions in the plants. Table 14.2 lists typical consumption rates for key processing requirements.

**Table 14.2 - Processing Facilities Consumables**

| Parameter | 2022 Value |
| --- | --- |
| Energy for Process (kWh/t ore) | 18 |
| Fresh Water (gpm) | 20,000 |
| Process Water Recycle (gpm) | 59,000 |
| Mill Liners (kg steel/t ore) | 0.05 |
| Grinding Balls (kg steel/t ore) | 0.6 |
| Primary Collector (g/t ore) | 65 |
| Secondary Collector (g/t ore) | 12 |
| Frother (g/t ore) | 25 |
| Lime (kg/t ore) | 0.3 |
| Flocculant (g/t ore) | 9 |
| Diesel (gal/t copper concentrate) | 1.7 |

Consumable and personnel requirements for the processing facilities are expected to be near current levels in the near-term with variation dependent on production levels in the various unit operations. As of December 31, 2022, the MP74 concentrating area and portsite dewatering plant had 612 PT-FI employees and 1,283 contractors for a total staffing of 1,895.

#### 14.3 Future Processing Capital Projects

The projects listed below are included in the LOM plan and are necessary to achieve the stated mill tonnages, recoveries, and concentrate grades. The process design criteria is informed by data from laboratory testing at bench scale and if necessary, at the pilot plant scale:

##### SAG3

- SAG3 is required to achieve total mill capacity that is in line with the historical nominal value of 240,000 metric tons of ore per day. This is because the underground ore is no longer transferred to the mill via ore passes of 600-meter vertical height which naturally provided a significant amount of gravity assisted comminution, as was the case for the now depleted Grasberg open-pit ore. SAG3 is expected to be operational in 2023.

Technical Report Summary for
Grasberg minerals district, Central Papua, Indonesia

Copper Cleaner

- The current SAG concentrator copper cleaner circuit is undersized for the higher rougher concentrate production volumes associated with GBC and KL ore due to higher pyrite levels than previously experienced with open-pit ores.
- The new copper cleaner will improve concentrate grade and recovery by increasing rougher flotation capacity, adding regrind power with the use of high intensity grinding mill technology to improve mineral liberation, and installing a new 2-stage cleaner using staged flotation reactor cell technology. The new GBC copper cleaner is planned to be operational in 2024.

Pyrite Cleaner and Pyrite Tailings Storage

- In order to maintain the mill tailings at neutral geochemistry with a 50 percent factor of safety during the mine life, a pyrite flotation circuit is planned to be online in 2030. This circuit will treat copper cleaner tailings to float a stream known as pyrite tailings. The pyrite tailings will be pumped to the lowlands via slurry pipelines to a pyrite tailings storage facility. The balance of the cleaner tailings will report to the normal mill tailings stream.

Lowlands Limestone Plant

- This facility will deliver a ground limestone slurry directly to the tailing deposition area.
- In combination with the future Pyrite Cleaner and Pyrite Tailings Storage facility it will enhance the management of tailings geochemistry in the ModADA.

Vertical Pressure Filter #3 (VPA3)

- The current sustainable filtration capacity of the dewatering plant at portsite is 2.7M dmt per annum.
- A third pressure filter is being constructed to provide sustainable copper concentrate filtration capacity up to 3.3M dmt per annum.
- VPA3 is expected to be operational in 2023.

Ship-Loader #2

- The current shipping capacity for copper concentrate is 3.0M dmt per annum.
- A second load system will ensure adequate shipping capacity during peak production years from 2032 forward.

Makaha Lime Plant:

- A 300 tpd expansion of the Makaha lime plant that produces the milk-of-lime reagent, used for pH adjustment in flotation is planned for operation in 2029.

# 15 SITE INFRASTRUCTURE

The site infrastructure at the Grasberg minerals district has been established over the history of the project and supports the current operations. The current major mine infrastructure includes: waste rock storage facilities, temporary stockpiles, riverine tailings

# **15.1 Waste Rock Storage Facilities**

Waste rock stockpiles are used to store overburden and other waste rock materials that were produced during the development and production of the now depleted open-pit mine. The transition to underground mining was completed in 2019, eliminating the need for new overburden stockpiles. As of December 31, 2022, reclamation of the West Wanagon overburden stockpile is ongoing. Other highlands stockpiles are being regraded and the top surface capped with limestone. Monitoring of the stockpiles and storm water runoff will continue through the life of operations.

# **15.2 Mill Stockpiles**

Ore is delivered from the mines to an underground primary crusher where it is crushed and then conveyed to coarse ore mill stockpiles that feed the concentrators. Ore is conveyed from the mill stockpiles to the copper concentrators.

# **15.3 Controlled Riverine Tailings Management**

PT-FI operates a controlled riverine tailings management system including a deposition area named ModADA, located downstream of the milling operations on the southern coastal plain of the New Guinea island in Central Papua, Indonesia. Tailings produced at the mill in the highlands are transported roughly 45 kilometers downstream to the ModADA in the lowlands with an elevation of 0 to 150 meters by way of a steep, unnavigable river that originates near the mill. Deposited sediments in the ModADA comprise tailings from the mill and other mine-derived sediments, as well as naturally occurring sediment produced from erosive processes typical for the area. Engineered levees to the east and west of the ModADA running a total length of approximately 120 kilometers laterally contain the depositional footprint of the tailings and natural sediment in the land and estuary portions of the permitted deposition area.

The current ModADA levee system has been constructed over a period of many years and will continue to be constructed in future years for sediment management and flood protection. Trained site engineers and construction quality assurance crews conduct routine inspections of the levee system. A fiber-optic sensory system has been installed in the levees for redundant monitoring purposes.

# **15.4 Power and Electrical**

The Grasberg minerals district electrical power is supplied by a 198MW coal-fired plant at portsite and 130MW of diesel generator capacity located at the mill. A twin circuit 230kV transmission line connects the portsite area and main power plants to the mill and mine operations areas.

There is 30MW of installed power generating capacity (25MW of firm capacity) and a 20kV distribution system that provides power for the lowlands support areas including MP38, Lowlands Industrial Park and Kuala Kencana.

One of PT-FI's partners provides expertise in the area of maintaining and operating its power plants.

As a result of the changing ore body, energy requirements at the Grasberg minerals district are expected to increase due to ventilation needs and more intensive processing requirements. To support the additional anticipated energy requirements as the

Technical Report Summary for^{}[] Grasberg minerals district, Central Papua, Indonesia

underground operations ramp up to full capacity, PT-FI identified an opportunity to integrate a lower-carbon power source at our operations with the development of a new 129MW DFPP. PT-FI currently expects to complete construction of the new DFPP in early 2023 and, once permitted and operational, it is expected to provide the additional power necessary for the operations. It will also enable us to transition our older diesel generation equipment at the mill to backup status.

The DFPP will initially be commissioned using domestically produced biodiesel, as mandated by the government of Indonesia. However, it was designed to use high-efficiency dual-fuel reciprocating engines on a flexible platform that can operate on either diesel fuel or natural gas, providing optionality to adjust the fuel type and increase plant capacity in the future.

### **15.5 Water Usage**

Water sources for the Grasberg minerals district are a combination of naturally occurring mountain streams and water derived from underground operations.

Potable and domestic use water is sourced from the fresh water supply and distributed using a network of pipelines. Process facilities operate using a combination of fresh and recycled water from the concentrator dewatering system and outflows from the underground mines. The underground mines utilize water sourced from dewatering activities.

### **15.6 Product Handling**

Steel pipelines are used to transport copper concentrate from the mill to the dewatering and storage barn facilities at portsite. The concentrate is pumped in these pipelines to a ridge above the Tembagapura townsite from which it flows by gravity to the portsite. The pipelines are buried or laid on the shoulder of the access road.

Ship loading facilities transport the dried concentrate (dried to 9 percent moisture for dust control) from the storage barns to the dock at the portsite facilities in Amamapare, Central Papua. Incoming freight and fuel are also unloaded at a separate cargo dock at portsite for delivery to their ultimate destinations in the lowlands, Tembagapura, the mill area, or the mines.

### **15.7 Logistics, Supplies, and Site Administration**

The operation has common management and services, as well as a logistics network that includes warehouses, vehicles, and personnel required to distribute and store the large quantity of supplies used by the operation and its workforce. A bus service is provided to the workplaces. Helicopters service day-to-day operations and exploration activities. Planes operated by a privatized partner and commercial flights provide routine transportation to Jakarta and other cities in Indonesia.

PT-FI has ships under PT-FI control to transport fuel, supplies, and general cargo to the site. PT-FI maintains a number of purchasing offices in Indonesia as well as in Singapore and the U.S. Warehouses are maintained at various locations throughout the site.

The remote location of the project requires that the operation be completely self-sufficient with an infrastructure capable of sustaining over 20,000 employees and contractors, along with many of their dependents. As such, supporting infrastructure has been built,

improved, and expanded over the life of the project, including townsites providing employees with services ranging from retail stores, restaurants, residential facilities, schools, libraries, banks, postal services, training and recreational facilities, and health service facilities.

# 16 MARKET STUDIES

The Grasberg minerals district produces copper in a concentrate, with gold and silver also contained in the concentrate.

# 16.1 Market for Mine Products

Copper is an internationally traded commodity and its prices are determined by the major metal exchanges. Prices on these exchanges generally reflect the worldwide balance of copper supply and demand and can be volatile and cyclical. In general, demand for copper reflects the rate of underlying world economic growth, particularly in industrial production and construction. FCX believes copper will continue to be essential in these basic uses as well as contribute significantly to new technologies for clean energy, to advance communications and to enhance public health.

Gold and silver are used for jewelry, coinage, and bullion as well as various industrial and electronic applications. Gold and silver can be readily sold on numerous markets throughout the world. Benchmark prices are generally based on London Bullion Market Association (London) quotations.

FCX owns smelting, refining, and product conversion facilities for copper products, operated as separate business segments. Sales between FCX's business segments are based on terms similar to arms-length transactions with third-parties at the time of the sale.

PT-FI sells its copper concentrate at market rates to major copper smelters worldwide as well as to major trading companies with whom FCX has built and maintained long-term relationships. PT-FI's sales agreements with major trading companies are generally established annually, although some extend unless or until terminated with 1-year notice. The pricing provisions in PT-FI's concentrate sales agreements are consistent with international terms and conditions for the sale of copper concentrates and are relatively standardized. The underlying copper price is determined by and fluctuates with, the commodity exchange price while the treatment and refining charges and premiums are negotiated annually based on market conditions.

# 16.2 Commodity Price Assumptions and Contracts

Long-term metal prices reported are used to demonstrate the economic viability of the mineral reserves and should not be construed as a prediction of future commodity prices. Assumed prices for mineral reserve estimation are:

- $3.00 per pound for copper
- $1,500 per ounce for gold
- $20 per ounce for silver

Technical Report Summary for
Grasberg minerals district, Central Papua, Indonesia

All contracts currently necessary for supplies and services to maintain the Grasberg minerals district's facilities and production are in place and are anticipated to be renewed or replaced within timeframes and conditions of common industry practices.

FCX and the QPs believe that the marketing and metal price assumptions for metal products are suitable to support the financial analysis of the mineral reserve evaluation. Further information regarding the sale and marketing of the mines' metal products are discussed in FCX's Annual Report on Form 10-K for the year ended December 31, 2022.

# 17 ENVIRONMENTAL STUDIES, PERMITTING, AND SOCIAL IMPACT

The Grasberg minerals district adheres to FCX's environmental and sustainability programs, including policies and management systems regarding environmental, permitting, and community issues. The Grasberg minerals district has implemented an Environmental Management System that is certified to the internationally recognized ISO-14001:2015 standard. FCX's programs are based on policies and systems that align with the International Council on Mining and Metals Sustainable Development Framework and the Copper Mark. FCX routinely evaluates implementation of these policies through internal and external independent assessments and publicly reports on its performance.

Further discussion regarding environmental, permitting, and social or community impacts is available in the latest FCX Annual Report on Sustainability.

# 17.1 Environmental Considerations

Environmental monitoring is ongoing at the Grasberg minerals district and will continue over the life of the operations and beyond through closure. Key monitoring areas include air, surface and ground water, waste management, reclamation, and biodiversity of terrestrial and aquatic ecosystems. PT-FI continues to monitor these baselines and impact studies regularly at compliance and voluntary points and reports results to required agencies.

Various changes in mining techniques and processing options have been implemented as a result of the depletion of the Grasberg open-pit in 2019. Updated environmental impact studies, environmental management and monitoring plans have been completed and are currently under review by the GOI.

PT-FI is currently in the process of completing an AMDAL for facilities and activities associated with the transition from open-pit mining to underground operations, including the addition of a new SAG unit at the mill, construction of additional power facilities at the port, and southern extension of tailings containment structures to safely maintain the tailings footprint approved by the 300k AMDAL.

# 17.2 Permitting

FCX and PT-FI believe that all major permits and approvals are in place to support operations at the Grasberg minerals district; however, additional permits will likely be necessary in the future. PT-FI holds multiple permits from national, provincial, and regency regulatory agencies, including groundwater use permits, effluent and air discharge permits, solid and hazardous waste storage and management permits and protection of forest borrow-to-use permits. Where permits have specific terms, renewal applications are made to the relevant regulatory authority as required, prior to the end of the permit term.

Technical Report Summary for^{}[] Grasberg minerals district, Central Papua, Indonesia

PT-FI routinely reports monitoring results to the Mimika Regency and provincial Central Papua Government as well to the MoEF. The MoEF issued to PT-FI Borrow to Use of Forest Area Permits (IPPKH), and the Determination of Planting Locations for Watershed Rehabilitation. Under conditions of the IPPKH issuance, PT-FI is legally required to revegetate an equal area of previously degraded land.

Permitting continues to progress for certain facilities related to the expansion of underground mining production operations as well as for additional tailings retention structures necessary to continue to contain the lateral deposition of tailings within the approved lowlands footprint. In 2020, PT-FI initiated a new AMDAL in preparation for the proposed activities associated with the transition from Grasberg surface to underground operations. PT-FI continues to work with the MoEF to complete the approval requirements of the AMDAL, which is currently estimated to be received in 2023. PT-FI has completed the initial regulatory review of technical approvals associated with the current AMDAL filing, and is now undergoing AMDAL Commission review and public consultations.

### **17.3 Waste and Tailings Storage, Monitoring, and Water Management**

PT-FI has developed and continues to implement detailed, comprehensive mine waste rock and tailings management programs to meet regulations and FCX environmental management practices. PT-FI also follows FCX's Tailings Management Policy.

PT-FI operates a controlled riverine tailings management system implemented based on methods approved and permitted by the GOI. Tailings are transported from the concentrating facility along with water and a small quantity of concentrating reagents. Reagents added as part of the concentrating process have been demonstrated to dissipate within a short distance from the concentrating facility.

The PT-FI tailings management system uses an unnavigable river to transport the tailings and other mine-derived sediments from the concentrator area in the highlands along with natural sediments to a large engineered and managed deposition area in the lowlands, called the ModADA. The river is not used for potable water, agriculture, fishing or other domestic or commercial uses. Levees have been constructed on both the east and west sides of the ModADA to laterally contain the depositional footprint of the tailings and natural sediment within the designated area. Small volumes of finer tailings and other sediments deposit in the estuary and the sea to the south.

PT-FI is also actively engaged with the MoEF's Tailings RoadMap Task Force, which is engaging third-party expertise to examine the viability of additional management techniques and activities, which may increase sediment retention, prevent future erosion, create new habitat, and identify beneficial uses of tailings as a resource.

### **17.4 Mine Closure Plans**

A detailed mine closure plan and 5-year reclamation plan have been approved by GOI regulators as required by Indonesia law. The plans are reviewed annually and revised every 5 years. Required reclamation bonds are in place. In the future, additional approval will be required for the diversion of the Aghawagon/Otomona River out of the ModADA at the end of mine life.

PT-FI completed an updated mine closure plan in June 2019 to reflect Grasberg minerals district production operations until 2041. On July 2, 2019, PT-FI obtained approval for changes to the mine closure plan through the Decree of the Directorate General of Mineral

as of December 31, 2022

Technical Report Summary for^{}[] Grasberg minerals district, Central Papua, Indonesia

and Coal. The total closure cost estimate in the LOM plan is approximately $1.3 billion based on a cash flow schedule for the implementation of closure and post closure tasks, including spending beyond 2041. PT-FI has complied with the annual renewal of the financial guarantees corresponding to the closure plan.

### **17.5 Local Stakeholder Considerations and Agreements**

As part of the ongoing permitting and compliance obligations with the regional and national agency authorizations and as part of the mines' commitment to local stakeholder engagement, PT-FI is dedicated to local community and social matters. PT-FI seeks to conduct its activities in a transparent manner that promotes proactive and open relationships with the local community, government, and other stakeholders to maximize the positive impacts of its operations and mitigate potential adverse impacts throughout the LOM plan.

PT-FI recognizes the rights of the Indigenous Peoples living within its project area and works with local stakeholders to address these rights on an ongoing basis. This can include land rights agreements, provision of community development programs involving the construction of housing, places of worship, community centers and health and education infrastructure, as well as provision of employment opportunities.

In 1996, PT-FI established a social investment fund with the aim of contributing to social and economic development in the Mimika Regency. Prior to 2019, the fund was mainly managed by the Amungme and Kamoro Community Development Organization, a community-led institution. In 2019, a new foundation, the Amungme and Kamoro Community Empowerment Foundation (Yayasan Pemberdayaan Masyarakat Amungme dan Kamoro, or YPMAK), was established, and in 2020, PT-FI appointed YPMAK to assist in distributing a significant portion of PT-FI's funding to support the development and empowerment of the local Indigenous Papuan people. YPMAK is governed by a Board of Governors consisting of seven representatives, including four from PT-FI.

In addition, since 2001, PT-FI has voluntarily established and contributed to land rights trust funds administered by Amungme and Kamoro representatives that focus on socioeconomic initiatives, human rights, and environmental issues.

PT-FI seeks to prioritize local and regional purchases and hiring with the additional objectives to promote community development through the prioritization of acquisition of local and regional goods and services, according to its requirements and technical specifications.

### **17.6 Comment on Environmental Compliance, Permitting, and Local Engagement**

In the QP's opinion, the Grasberg minerals district has adequate plans and programs in place, is in good standing with Indonesian environmental regulatory authorities, and no current conditions related to environmental compliance, permitting, and local engagement represent a material risk to continued operations. The Grasberg minerals district staff has a high level of understanding of the requirements of environmental compliance, permitting, and local stakeholders in order to facilitate the development of the mineral reserve and mineral resource estimates. The periodic inspections by governmental agencies, FCX corporate staff, third-party reviews, and regular reporting confirm this understanding.

# 18 CAPITAL AND OPERATING COSTS

The capital and operating costs are estimated by the property's operations, engineering, management, and accounting personnel in consultation with FCX corporate staff, as appropriate. The cost estimates are applicable to the planned production, mine schedule, and equipment requirements for the LOM plan. The capital costs are summarized in Table 18.1.

Table 18.1 - Capital Costs

|  | $ billions |
| --- | --- |
| Mine | $7.9 |
| Concentrator | 4.3 |
| Supporting Infrastructure | 2.4 |
| Total Capital Expenditures | $14.5 |

Estimates are derived from current costs and adjusted to the reserve price environment. The estimates are not adjusted for escalation or exchange rate fluctuations. Actual realized costs are reviewed periodically and estimates are refined as required.

Capital costs include development and sustaining projects for the production of the scheduled reserves. Capital cost estimates are derived from current capital costs based on extensive experience gained from many years of operating the property and do not include future inflation. FCX and the PT-FI mine staff review actual costs periodically and refine cost estimates as appropriate.

Mine capital costs include development of the KL ore body as well as sustaining development for the GBC and DMLZ deposits. Concentrator capital costs include sustaining capital for the mill complex as well as capital expenditures at the processing facilities to optimize the handling of underground ore from the GBC, DMLZ and KL deposits. Increases in power loads at these processing facilities and the underground mines are expected to require additional power generation with capital expenditures for new power generation, upgrades to existing transmission lines, and refurbishment of the existing three coal units.

The operating costs for the LOM plan are summarized in Table 18.2.

Estimates are derived from current costs and adjusted to the reserve price environment. The estimates are not adjusted for escalation or exchange rate fluctuations. Actual realized costs are reviewed periodically and estimates are refined as required.

The operating cost estimates are derived from current operating costs and practices based on extensive experience gained from many years of operating the property and do not include future inflation. The operating cost estimates reflect certain pricing assumptions, primarily for energy and foreign exchange rates, that are reflective of the copper market environment ($3.00 per pound copper price) at which the reserve plan has been prepared. As the property has a long operating history, FCX believes that the accuracy of the cost estimates is better than the minimum of approximately +/- 25 percent required for a pre-feasibility study level of mineral reserves as per S-K1300, and the level of risk in the cost forecasting is low. FCX and the PT-FI mine staff review actual costs periodically and refine cost estimates as appropriate.

The LOM plan summary in this TRS is developed to support the economic viability of the mineral reserves. The latest guidance regarding updated operational forecast cost estimates is available in FCX's Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC.

## 19 ECONOMIC ANALYSIS

The LOM plan includes comprehensive operational drivers (mine and corresponding processing plans, metal production schedules, and corresponding equipment plans) and financial estimates (revenues, capital costs, operating costs, downstream processing, freight, taxes, and royalties, etc.) to produce the reserves over the life of the property. The LOM plan is an operational and financial model that also forecasts annual cash flows of the production schedule of the reserves for the life of the property under the assumed pricing and cost assumptions. The LOM plan is used for economic analyses, sensitivity testing, and mine development evaluations.

The financial forecast incorporates revenues and operating costs for all produced metals, processing streams, and overall site management for the life of the property. The economic analysis summary in Table 19.1 includes the material drivers of the economic value for the property and includes the net present value (NPV) of the unleveraged after-tax free cash flows as the key metric for the economic value of the property's reserve plan under these pricing and cost assumptions. This analysis does not include economic measures such as internal rate of return or payback period for capital since these measures are not applicable (and are not calculable) for an on-going operation that does not have a significant upfront capital investment to be recovered.

Table 19.2 summarizes the economic impact of changes to these key drivers on the property's NPV (as included in Table 19.1). The sensitivities are estimates for the changes in each key drivers' effect on the base plan summarized for the production of the mineral reserves over the life of the property.

**Table 19.2 - Sensitivity Analysis**

| Sensitivity Analysis ($ billions) | Incremental Impact to NPV |  |
| --- | --- | --- |
|  | +5% Change | -5% Change |
| Copper price | $1.57 | ($1.57) |
| Gold price | 0.69 | (0.69) |
| Copper grade/recovery | 1.44 | (1.44) |
| Gold grade/recovery | 0.70 | (0.70) |
| Capital cost | (0.39) | 0.39 |
| Operating cost | (0.78) | 0.78 |
| Discount rate | (0.61) | 0.64 |

Sensitivity analysis does not reflect changes in mine plans or costs with changes in above items.

The after-tax NPV of the LOM plan is most sensitive to price, followed by grades and recovery, and then operating costs. The sensitivity analysis does not reflect changes in mine plans or costs with changes in the reported driver. Sustained periods in these economic scenarios would warrant a re-evaluation of the LOM plan assumptions, planned development, and reported mineral reserves.

Table 19.3 summarizes the LOM plan including the annual metal production volumes, mine plan schedule, capital and operating cost estimates, unit net cash costs, and unleveraged after-tax free cash flows over the life of the property. Free cash flow is the operating cash flow less the capital costs and is a key metric to demonstrate the cash that the property is projected to generate from its operations after capital investments for the reserve production plan at assumed pricing and cost assumptions. The property's ability to create value from the reserves is determined by its ability to generate positive free cash flow.

Grasberg minerals district, Central Papua, Indonesia

minerals district are available in FCX's Annual Report on Form 10-K for the year ended December 31, 2022.

## **22 INTERPRETATION AND CONCLUSIONS**

Estimates of mineral reserves and mineral resources are prepared by and are the responsibility of FCX employees. All relevant geologic, engineering, economic, metallurgical, and other data is prepared according to FCX developed procedures and guidelines based on accepted industry practices. FCX maintains a process of verifying and documenting the mineral reserve and mineral resource estimates, information for which are located at the mine site and FCX corporate offices. FCX conducts ongoing studies of its ore bodies to optimize economic value and to manage risk.

FCX and the QPs believe that the geologic interpretation and modeling of exploration data, economic analysis, mine design and sequencing, process scheduling, and operating and capital cost estimation have been developed using accepted industry practices and that the stated mineral reserves and mineral resources comply with SEC regulations. Periodic reviews by third-party consultants confirm these conclusions.

The Grasberg minerals district is a large-scale producing mining property that has been operated by FCX and its predecessors for many years. Mineral reserve and mineral resource estimates consider technical, economic, environmental, and regulatory parameters containing inherent risks. Changes in grade and/or metal recovery estimation, realized metal prices, and operating and capital costs have a direct relationship to the cash flow and profitability of the mines. Other aspects such as changes to environmental or regulatory requirements could alter or restrict the operating performance of the mines. Significant differences from the parameters used in this TRS would justify a re-evaluation of the reported mineral reserve and mineral resource estimates. Mine site administration and FCX dedicate significant resources to managing these risks.

## **23 RECOMMENDATIONS**

Although ongoing initiatives in productivity and recovery improvements are underway, the mineral reserves and mineral resources are based on the stated long-term metal prices and corresponding technical and economic performance data.

No recommendations for additional work are identified for the reported mineral reserves and mineral resources as of December 31, 2022.

These closely integrated departments are focused on subjects that may be peripheral to the direct production of salable metals but are essential to meeting all business requirements for FCX and to navigating the many aspects of modern mining.

As an illustrative example of the FCX organization, within the Office of President, there are departments of Financial and Operational Analysis, Information Services, Administration and Sales, Business Development and Growth, General Counsel, Global Strategic Relations, Government Relations, Communications, Finance, Accounting, Tax, and Investor Relations. Other corporate teams are similarly organized to provide additional broad services. These departments support and integrate with the operating divisions providing requirements and information. A mine site, as part of the operating divisions, will be organized into its own management teams including Mine Management, Operations, Maintenance and Construction, Processing Management, Finance and Accounting, Social Responsibility and Community Development, Environmental, Regional Supply Chain, and Human Resources. These staffed teams are organized to provide responses to the many mining requirements, and they have experience in conducting their specific duties. They represent reliable sources for information and as such, they have been consulted to prepare, support, and characterize the information in this TRS.

Specific to the preparation of this TRS, FCX departments have provided the following categories of information:

- Macro-economic trends, data, interest rates, and assumptions.
- Marketing information.
- Legal matters outside of QP expertise.
- Environmental matters outside of QP expertise.
- Accommodations through community development to local groups.
- Governmental factors outside of QP expertise.

The QPs prepared Sections 3, 4, 5, 15, 16, 17, 18, 19, 20, and 21 of this TRS in reliance on the information provided by FCX above.

As explained, FCX corporate and mine site divisions that provided information for this TRS are business-directed areas that must produce reliable information in support of FCX business objectives. This organizational form contributes to producing expected results for FCX and provides appropriate information supporting mineral reserves and mineral resource estimates.

Technical Report Summary for^{}[] Morenci Mine, Arizona, U.S.

# 1 EXECUTIVE SUMMARY

This Technical Report Summary (TRS) is prepared by Qualified Persons (QPs) for Freeport-McMoRan Inc. (FCX), a leading international mining company with headquarters located in Phoenix, Arizona, United States (U.S.). The purpose of this TRS is to report mineral reserve and mineral resource estimates at the Morenci mine using estimation parameters as of December 31, 2022.

## 1.1 Property Description, Current Status, and Ownership

The Morenci mine is an open-pit copper and molybdenum mining complex. The mine is located in Greenlee County, Arizona, approximately 50 miles northeast of the city of Safford on U.S. Highway 191.

The mine operates 365 days per year on a 24 hour per day schedule. Mining and ore processing operations are currently in production and the mine is considered a production stage property.

The Morenci mine is an unincorporated joint venture owned 72 percent by FCX, with the remaining 28 percent owned by Sumitomo Metal Mining Arizona, Inc. (15 percent) and SMM Morenci, Inc. (13 percent). Each partner takes in kind its share of Morenci's production. FCX is the operator of the joint venture and holds registered title to the mineral claims.

As of December 31, 2022, the Morenci mine encompasses approximately 61,700 acres, comprising 51,300 acres of fee lands and 10,400 acres of unpatented mining claims held on public mineral estate and numerous state or federal permits, easements, and rights-of-way.

## 1.2 Geology and Mineralization

The mineral deposits of the Morenci district consist of copper oxide, secondary sulfide, and primary sulfide mineralization associated with a large porphyry copper system. Geologic studies indicate that a complex series of Tertiary igneous intrusive rocks were emplaced within Precambrian-age granite and overlying Paleozoic and Mesozoic sedimentary rocks. A porphyry copper deposit formed and was associated with the emplacement and crystallization of intrusive rocks. Several cycles of leaching and enrichment of the primary sulfides formed the secondary sulfide enrichment blanket and copper oxide zones currently being mined. Mineralization spans approximately 5 miles in a north-south direction and 4 miles in an east-west direction.

## 1.3 Mineral Reserve Estimate

Mineral reserves are summarized from the Life-of-Mine (LOM) plan, which is the compilation of the relevant modifying factors for establishing an operational, economically viable mine plan.

Mineral reserves have been evaluated considering the modifying factors for conversion of measured and indicated resource classes into proven and probable reserves. Inferred resources are considered to be waste in the LOM plan. The details of the relevant modifying factors included in the estimation of mineral reserves are discussed in Sections 10 through 21.

as of December 31, 2022

**FREEPORT-McMoRAN**

Technical Report Summary for
Morenci Mine, Arizona, U.S.

The LOM plan includes the planned production to be extracted from the in-situ mine designs and from previously extracted material, known as Work-In-Process (WIP) inventories. WIP includes material on crushed leach and Run of Mine (ROM) leach pads for processing, and in stockpiles set aside to be rehandled and processed at a future date. WIP is estimated as of December 31, 2022, from production of reported deliveries through mid-year and the expected production to the end of the year.

As a point of reference, the mineral reserve estimate reports the in-situ ore and WIP inventories from the LOM plan containing copper and molybdenum metal and reported as commercially recoverable metal.

Table 1.1 summarizes the mineral reserves reported on a 100 percent and pro rata property ownership basis. The mineral reserve estimate is based on commodity prices of $3.00 per pound for copper and $12 per pound for molybdenum.

assumed conditions. All the technical and economic issues likely to influence the prospect
of economic extraction are anticipated to be resolved under the stated assumed
conditions.

### 1.4 Mineral Resource Estimate

Mineral resources are evaluated using the application of technical and economic factors
to a geologic resource block model and employing optimization algorithms to generate
digital surfaces of mining limits, using specialized geologic and mine planning computer
software. The resulting surfaces volumetrically identify material as potentially economical,
using the assumed parameters. Mineral resources are the resultant contained metal
inventories.

The mineral resource estimate is the inventory of material identified as having a
reasonable likelihood for economic extraction inside the mineral resource economic
mining limit, less the mineral reserve volume, as applicable. The modifying factors are
applied to measured, indicated, and inferred resource classifications to evaluate
commercially recoverable metal. As a point of reference, the in-situ ore containing copper
and molybdenum metal is inventoried and reported by intended processing method.

The reported mineral resource estimate in Table 1.2 is exclusive of the reported mineral
reserve, on a 100 percent and pro rata property ownership basis. The mineral resource
estimate is based on commodity prices of $3.50 per pound for copper and $15 per pound
for molybdenum.

Notes

a. Reported as of December 31, 2022 using metal prices of $3.50 per pound copper and $15 per pound molybdenum. Mineral resources are exclusive of mineral reserves.
b. Amounts may not foot because of rounding.
c. Internal cutoff grade reported as equivalent copper (EqCu).
d. Estimated expected recoveries are consistent with those for mineral reserves but would require additional work to substantiate.
e. The Morenci mine is an unincorporated joint venture owned 72 percent by FCX, with the remaining 28 percent owned by Sumitomo Metal Mining Arizona, Inc. (15 percent) and SMM Morenci, Inc. (13 percent). Each partner takes in kind its share of Morenci's production. FCX is the operator of the joint venture and holds registered title to the mineral claims.

The mineral resource estimate has been prepared using industry accepted practice and conforms to the disclosure requirements of S-K1300. Mineral reserve and mineral resource estimates are evaluated annually, providing the opportunity to reassess the assumed conditions. Although all the technical and economic issues likely to influence the prospect of economic extraction of the estimated mineral resource are anticipated to be resolved under the stated assumed conditions, no assurance can be given that the estimated mineral resource will become proven and probable mineral reserves.
