**Pan American Silver Reports Mineral Reserves and Mineral Resources as at June 30, 2025**

**Vancouver, B.C. - September 11, 2025** - **Pan American Silver Corp.** (NYSE: PAAS) (TSX: PAAS) ("Pan American" or the "Company") is pleased to report its estimated mineral reserves and mineral resources as at June 30, 2025. Proven and probable ("P&P") mineral reserves are estimated to contain approximately 452.3 million ounces of silver and 6.3 million ounces of gold. Measured and indicated ("M&I") mineral resources (excluding P&P mineral reserves) are estimated to total approximately 1,130.6 million ounces of silver and 9.9 million ounces of gold. Inferred mineral resources are estimated to total approximately 405.6 million ounces of silver and 8.6 million ounces of gold.

"Our exploration program at La Colorada has enabled us to more than replace production at that mine as well as add 52.7 million ounces of silver in the inferred mineral resource category, mostly in the newly discovered high-grade silver zones reported in the news release dated September 8, 2025," said Christopher Emerson, Pan American's Senior Vice President of Exploration and Geology. "Exploration success across our portfolio continues to extend the life of many of our operations."

This news release does not report on, nor include, the estimated mineral reserves and mineral resources resulting from Pan American's acquisition of MAG Silver Corp. ("MAG"). Pan American completed the acquisition of MAG on September 4, 2025, which added a 44% joint venture interest in the large-scale, high-grade Juanicipio silver mine in Zacatecas, Mexico, operated by Fresnillo plc, along with MAG's interests in the Deer Trail and Larder exploration projects (collectively, the "MAG Properties"). For information regarding the MAG Properties, please see MAG's Annual Information Form dated March 24, 2025, available under MAG's profile at www.sedarplus.ca.

**Mineral reserve and mineral resource highlights for the 12-months ended June 30, 2025:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• At La Colorada, the eastward extension of the veins and addition of contact-type mineralization in the Manto Sur zone described in a news release dated September 8, 2025, contributed to an estimated 52.7 million ounce increase in silver inferred mineral resources.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• At Timmins, exploration focused on the Timmins West mine (Timmins mine, 144 Gap and Samson zones) and drilling at depth at the Bell Creek mine added an estimated 105.4 thousand ounces of gold M&I mineral resources and 163.8 thousand ounces of gold inferred mineral resources.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• At Jacobina, the majority of mine production was replaced through successful exploration and infill drilling, with the initial reporting of new mineral reserves for the Maricota zone.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• At El Peñon, essentially 100% of the silver production and 78% of the gold production was replaced. Exploration success was realized in the Pampa Campamento Norte and Chiquilla Chica zones.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Consolidated M&I silver mineral resources have not changed significantly from an estimated 1,148.0 million ounces as at June 30, 2024 to an estimated 1,130.6 million ounces as at June 30, 2025, excluding M&I resources acquired through the acquisition of MAG.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Consolidated M&I gold mineral resources decreased from an estimated 15.5 million ounces to an estimated 9.9 million ounces, largely driven by the sale of the La Arena mine and the Joaquin property.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The divestment of the La Arena mine led to a reduction of 241.5 thousand ounces of gold mineral reserves, 17.6 thousand ounces of gold M&I mineral resources, and 39.6 thousand ounces of gold inferred mineral resources. The associated divestment of the La Arena II project resulted in a reduction of 5.3 million ounces of gold M&I mineral resources and 445.2 thousand ounces of gold inferred mineral resources.

------

The Company has undertaken a verification process with respect to the data disclosed in this news release. The mineral resources and mineral reserves databases comprising drilling and, in some cases, surface and underground sampling, have been compiled at each of the Pan American mine sites by the qualified staff. All the assay data used in the resource evaluation provided by each of the mines has been subjected to the industry standard quality assurance and quality control ("QA/QC") program including the submission of certified standards, blanks, and duplicate samples. The results are reviewed monthly by management. The results of the QA/QC samples submitted for the resource databases demonstrate acceptable accuracy and precision. The Qualified Person is of the opinion that the sample preparation, analytical, and security procedures followed for the samples are sufficient and reliable for the purpose of these mineral resource and mineral reserve estimates. Pan American is not aware of any drilling, sampling, recovery or other factors that could materially affect the accuracy or reliability of the data reported herein.

Quantities and grades of contained metal are shown before metallurgical recoveries.

For further information on the Company's pre-MAG transaction material mineral properties, including detailed information concerning associated QA/QC and data verification matters, the key assumptions, parameters and methods used by the Company to estimate mineral reserves and mineral resources, and for a detailed description of known legal, political, environmental, and other risks that could materially affect the Company's business and the potential development of the Company's mineral reserves and mineral resources, see the Company's Annual Information Form dated February 19, 2025, available on the Company's profile at www.sedarplus.ca.

**Cautionary Note Regarding Forward-Looking Statements and Information**

Certain of the statements and information in this news release constitute "forward-looking statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995 and "forward-looking information" within the meaning of applicable Canadian provincial securities laws. All statements, other than statements of historical fact, are forward-looking statements or information. Forward-looking statements or information in this news release relate to, among other things: estimated mineral reserve and mineral resource information; estimated mine life and any anticipated changes related thereto; the extent of, and success related

to any future exploration or development programs; expectations that metallurgical, environmental, permitting, legal, title, taxation, socio-economic, political, marketing or other issues will not materially affect estimates of mineral reserves and mineral resources; expectations regarding planned drilling in 2025, including that it will be focused on near-mine exploration; expectations regarding mineral reserve replacement; and Pan American's planned sale of its interest in La Pepa.

These forward-looking statements and information reflect the Company's current views with respect to future events and are necessarily based upon a number of assumptions that, while considered reasonable by the Company, are inherently subject to significant operational, business, economic and regulatory uncertainties and contingencies. These assumptions include: the accuracy of our mineral reserve and mineral resource estimates and the assumptions upon which they are based; ore grades and recoveries are as anticipated; prices for silver, gold, and base metals remaining as estimated; currency exchange rates remaining as estimated; capital, decommissioning and reclamation estimates; prices for energy inputs, labour, materials, supplies and services (including transportation); all necessary permits, licenses and regulatory approvals for our operations are received in a timely manner; our ability to secure and maintain title and ownership to properties and the surface rights necessary for our operations, including contractual rights from third parties and adjacent property owners; and our ability to comply with environmental, health and safety laws. The foregoing list of assumptions is not exhaustive.

The Company cautions the reader that forward-looking statements and information involve known and unknown risks, uncertainties and other factors that may cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements or information contained in this news release and the Company has made assumptions and estimates based on or related to many of these factors. Such factors include, without limitation: fluctuations in silver, gold and base metal prices; fluctuations in prices for energy inputs, labour, materials, supplies and services (including transportation); fluctuations in currency markets (such as the PEN, MXN, ARS, BOB, CLP, BRL, GTQ and CAD versus the USD); operational risks and hazards inherent with the business of mining (including environmental accidents and hazards, industrial accidents, equipment breakdown, unusual or unexpected geological or structural formations, cave-ins, flooding and severe weather); employee relations; relationships with, and claims by, local communities and indigenous populations; our ability to obtain all necessary permits, licenses and regulatory approvals in a timely manner; changes in laws, regulations and government practices in the jurisdictions where we operate, including environmental, export and import laws and regulations; legal restrictions relating to mining; risks relating to expropriation; diminishing quantities or grades of mineral reserves as properties are mined; increased competition in the mining industry for equipment and qualified personnel; and those factors identified under the caption "Risks Related to Pan American's Business" in the Company's most recent form 40-F and Annual Information Form filed with the United States Securities and Exchange Commission (the "SEC") and Canadian provincial securities regulatory authorities, respectively. Although the Company has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated, described or intended. Investors are cautioned against undue reliance on forward-looking statements or information. Forward-looking statements and information are designed to help readers understand management's current views of our near and longer term prospects and may not be appropriate for other purposes. The Company does not intend, nor does it assume any obligation to update or revise forward-looking statements or information, whether as a result of new information, changes in assumptions, future events or otherwise, except to the extent required by applicable law.

**Cautionary Note to US Investors Regarding References to Mineral Reserves and Mineral Resources**

Unless otherwise indicated, all reserve and resource estimates included in this news release have been prepared in accordance with NI 43-101 and the CIM Standards. NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, differ significantly from the mineral property disclosure requirements of the SEC (the "U.S. Rules"), and reserve and resource information included herein may not be comparable to similar information disclosed by U.S. companies. In particular, and without limiting the generality of the foregoing, this news release uses the terms "measured resources," "indicated resources" and "inferred resources" as defined in accordance with NI 43-101 and the CIM Standards.

------

Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable. Further, "inferred mineral resources" have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Under Canadian securities laws, estimates of "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies, except in rare cases. While the above terms under the U.S. Rules are "substantially similar" to the standards under NI 43-101 and CIM Standards, there are differences in the definitions under the U.S. Rules and CIM Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as "proven mineral reserves", "probable mineral reserves", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the standards adopted under the U.S. Rules.
