RER holds a 100% interest in the Bear Lodge rare earth elements project (the "Bear Lodge REE Project") located near the town of Sundance in northeast Wyoming. The Bear Lodge REE Project consists of several large, disseminated rare earth elements ("REE") deposits having a favorable distribution of neodymium-praseodymium (NdPr), as well as a number of other critical REEs. Additionally, the Company has developed and enhanced, along with General Atomics and its affiliates, innovative and proprietary REE processing and separation capabilities for the processing of the Bear Lodge REE Project feed material and possibly feed materials from other sources.

If and when developed, the Bear Lodge REE Project will likely consist of a mine and a separation plant to produce a commercial NdPr product. As market conditions dictate, the Company will decide whether it is prudent to develop and put into production the mine and separation plant independent of each other or whether linking the two production processes into a single project is the more prudent path.

The Company also holds a 100% interest in the Sundance Gold Project that is adjacent to the Bear Lodge REE Project and contains a historical inferred mineral resource primarily composed of three gold targets within the area of the Bear Lodge property. Given the Company's longstanding focus on the Bear Lodge REE Project and the current interest in REEs, the advancement of the Sundance Gold Project has been on hold since 2011 and will likely remain so for the foreseeable future.

The Company is currently focused on the advancement of a rare earth processing and separation demonstration-scale plant (the "Demonstration Plant") project. The Demonstration Plant will process already stockpiled high-grade sample materials from the Bear Lodge REE Project.

In January 2021, a consortium of companies, of which the Company is a part, received notice from the Department of Energy ("DoE") that the consortium had been selected for negotiation of a potential financial award for the engineering, construction and operation of a rare earth separation and processing demonstration plant, which is now the Demonstration Plant project. The consortium of companies is led by General Atomics, an affiliate of Synchron, the Company's majority shareholder, and includes certain of General Atomics' affiliates, the Company and LNV, an Ardurra Group, Inc. company, as engineering and construction subcontractor. The Company, as a subrecipient of the award, along with the other consortium members, commenced work on the planning and design of the Demonstration Plant project in November 2021, with the Company's contractual arrangement with General Atomics finalized in December 2021.

To address the Company's funding needs, including the funding required for the Demonstration Plant, the Company completed rights offerings in December 2021 (the "2021 Rights Offering") and March 2024 (the "2024 Rights Offering") for gross proceeds of approximately $25,400 and $35,800, respectively. The original $21,900 financial award from the DoE was expected to fund approximately one-half of the originally expected total cost of the Demonstration Plant project, with the balance of the required funding being provided by the Company utilizing the proceeds from the 2021 Rights Offering, the $4,400 grant from the Wyoming Energy Authority (the "WEA") as discussed in Note 5, and other funding sources, as necessary.

Since inception, the General Atomics-led consortium has seen increases in the Demonstration Plant's project costs, including final equipment costs, due to, among other factors, inflation. As a result of these cost pressures, General Atomics, on behalf of the consortium, submitted to the DoE an updated Demonstration Plant construction and operations budget in 2024 of approximately $53,600, which is approximately 22% higher than the original budget of approximately $43,800. In response, the DoE pledged an additional commitment of $2,400 (increasing its total commitment to approximately $24,200) in September 2024 to help fund a portion of this budget increase, with the balance to be funded by the Company utilizing the proceeds from the 2024 Rights Offering, including any amounts in excess of the $53,600 revised budget total, now estimated to be in excess of $66,000.

In December 2022, the Demonstration Plant achieved its final engineering design milestone, marking the DoE's first go/no-go decision point. A second go/no-go gating milestone was achieved in December 2023 with the issuance by the DoE of a Project Continuation Notice, allowing for the construction of the Demonstration Plant.

In September 2024, the DoE issued its final Project Continuation Notice following its approval of the revised project budget of $53,600 and confirmation of readiness for the operations phase of the Demonstration Plant. This notice, along with the U.S. Nuclear Regulatory Commission's (the "NRC") operations approval under its previously issued license (received by the Company in October 2024), allowed for the commencement of Demonstration Plant operations.

During the first half of 2025, several design and equipment issues were identified during the Demonstration Plant's equipment testing phase, which followed the completion of construction activities. As a result of these issues, an as-built design review was commenced in April 2025. The Company now expects plant commissioning to start in late 2025 and commencement of plant operations to begin in the first quarter of 2026.

**The Company has incurred losses since its inception, and further losses are anticipated in the development of its business. As of June 30, 2025, the Company had cash and cash equivalents of $23,050. During the six months ended June 30, 2025, we consumed cash of $3,537 in our operating activities, primarily associated with the Demonstration Plant project activities and for the payment of the Company's general and administrative expenses and other ongoing costs of sustaining its properties. Additional Demonstration Plant cost increases, now estimated to be in excess of $66,000, are expected and will likely have to be funded by the Company if the Company is unable to secure funding from other sources, which are currently being pursued but for which there can be no assurance of success.** 

The funds raised by the Company in the 2024 Rights Offering are expected to support the operations of the Demonstration Plant for a sufficient period of time to gather the information necessary for a commercialization decision. However, even with these funds and the expected receipt of the remaining WEA grant monies and DoE funds, the Company will still require substantial additional funds to complete the permitting and licensing, and ultimate construction and operation of a commercial mine and plant for the Bear Lodge REE Project. Ultimately, in the event the Company cannot secure additional financial resources, or complete a strategic transaction in the longer term, the Company may need to curtail or suspend the development and commercialization of its Bear Lodge REE Project or other initiatives, or potentially liquidate its business interests, and investors may lose all or part of their investment.

**2. BASIS OF ACCOUNTING AND PRESENTATION**

In accordance with U.S. GAAP for interim financial statements, these unaudited condensed consolidated financial statements do not include certain information and note disclosures that are normally included in annual financial statements prepared in conformity with U.S. GAAP. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements as of December 31, 2024, which were included in the Company's Annual Report on Form 10-K for the year ended December 31, 2024. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (which are of a normal, recurring nature) necessary to present fairly in all material respects the Company's financial position as of June 30, 2025, and the results of its operations and cash flows for the three and six months ended June 30, 2025 and 2024 in conformity with U.S. GAAP on a going concern basis. These interim results of operations for the six months ended June 30, 2025 may not be indicative of the results that will be realized for the full year ending December 31, 2025.

*Research & Development ("R&D") Expenditures*

Materials, equipment, and facilities acquired or constructed for R&D activities associated with the Company's Demonstration Plant project are expensed as incurred.

*Restricted Cash*

The Company periodically maintains cash deposits that are held and earmarked for a specific purpose. At June 30, 2025, the Company had $198 in restricted cash for amounts held by a third party as security for a surety bond for our Demonstration Plant.

3. FAIR VALUE OF FINANCIAL INSTRUMENTS

U.S. GAAP defines fair value as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price) and establishes a fair-value hierarchy that prioritizes the inputs used to measure fair value using the following definitions (from highest to lowest priority):

● Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

● Level 2 — Observable inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data by correlation or other means.

● Level 3 — Prices or valuation techniques requiring inputs that are both significant to the fair-value measurement and unobservable.

Financial assets and liabilities subject to fair value measurements on a recurring basis and the level of inputs used in such measurements by major security type as of June 30, 2025 and December 31, 2024 are presented in the following table:

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Fair value at June 30, 2025** | **Fair value at June 30, 2025** | **Fair value at June 30, 2025** | **Fair value at June 30, 2025** | **Fair value at June 30, 2025** |
|  | Total  | Level 1 | Level 2 | Level 3 |
| **Assets:** |  |  |  |  |
| &nbsp;&nbsp;Money market funds | $22885 | $22885 | $— | $— |
| **Fair value at December 31, 2024** | **Fair value at December 31, 2024** | **Fair value at December 31, 2024** | **Fair value at December 31, 2024** | **Fair value at December 31, 2024** |
|  | Total  | Level 1 | Level 2 | Level 3 |
| **Assets:** |  |  |  |  |
| &nbsp;&nbsp;Money market funds | $26449 | $26449 | $— | $— |

---

Money market funds are valued at cost, which approximates fair value. These amounts are included on the balance sheet in cash and cash equivalents at June 30, 2025 and December 31, 2024.

4. RELATED PARTY

Cost Share Agreement with General Atomics

In January 2021, a consortium of companies, of which the Company is a part, received notice from the DoE that the consortium had been selected for negotiation of a potential financial award for the engineering, construction, and operation of the Demonstration Plant. This consortium of companies is led by General Atomics, an affiliate of Synchron (the Company's majority shareholder), and includes certain of General Atomics' affiliates, the Company and LNV, an Ardurra Group, Inc. company, as engineering and construction subcontractor. A formal proposal was submitted by the consortium in response to a published Funding Opportunity Announcement in mid-2020 for the construction and operation of the Demonstration Plant utilizing proprietary technology to produce commercial-grade products. Under this original proposal, the DoE's share of the Demonstration Plant project funding was estimated at $21,900 and represented approximately one-half of the total originally estimated costs for the project. The DoE agreement was executed by the DoE's

grants/agreement officer on September 27, 2021, with an effective date of October 1, 2021. The DoE award was finalized through a cooperative agreement dated October 1, 2021 (the "Cooperative Agreement") that was awarded by the DoE for the Demonstration Plant. The Cooperative Agreement provided that up to approximately $43,800 in allowable costs for the Demonstration Plant were to be funded on a cost-share basis, 50% by the DoE and 50% by a non-federal entity.

On November 30, 2021, the Company and General Atomics entered into a Cost Share Funding Assumption Agreement (the "Cost Share Agreement") pursuant to which the Company agreed to assume and pay for the 50% of the non-federal funds incurred by, and on behalf of, General Atomics for the design, construction, and operation of the Demonstration Plant under the Cooperative Agreement. The Demonstration Plant will process already stockpiled high-grade sample materials from the Bear Lodge REE Project. Since inception, the Company has advanced $20,389 in funds to General Atomics under the Cost Share Agreement and has paid an additional $4,746 on General Atomics' behalf to certain contractors for work performed under the agreement.

On March 17, 2022, the Company executed a subcontract purchase order in the amount of $5,318 with General Atomics under which the Company agreed to provide certain services and materials to the Demonstration Plant project, including, but not limited to, providing the plant's sample materials, engaging in site location leases and other logistics, providing operational support, and providing decommissioning, bonding and other Demonstration Plant support activities (the "Subcontract Purchase Order"). In connection with the Subcontract Purchase Order, the Company submitted monthly invoices to General Atomics for the subcontracted services performed, which were reimbursed by General Atomics with one-half of the funds coming from funds advanced by the Company under the Cost Share Agreement and, up to the original Demonstration Plant budget, one-half of the funds from the DoE.

Due to inflationary cost pressures on labor, equipment, and consumables, as well as cost increases associated with certain optimized plant engineering and design parameters, General Atomics, on behalf of the consortium, submitted to the DoE an updated Demonstration Plant project budget of approximately $53,600, which is approximately 22% higher than the original budget of approximately $43,800. In response, the DoE pledged an additional cost-share funding commitment of $2,400 to fund a portion of the budget increase, with the balance coming from the Company, including any amounts in excess of the $53,600 revised budget total, now estimated to be in excess of $66,000. These additional funds are expected to support the operations of the Demonstration Plant for a sufficient amount of time to gather the information necessary for a commercialization decision.

On May 16, 2024, the Company and General Atomics entered into an extension agreement to the Cost Share Agreement (the "Extension Agreement") under which the Company agreed to make additional cash advances, of up to $2,500, to General Atomics while the parties progressed an amended project funding agreement covering the Company's share of the additional non-federal project funding needed for the project's completion. Pursuant to the terms of the Cost Share Agreement and Extension Agreement, the Company had advanced payments to General Atomics, as leader of the consortium, totaling $24,200 through October 31, 2024, the maximum amount of advances authorized under these agreements. In November 2024, General Atomics subsequently returned approximately $3,811 of the amounts previously funded by the Company under the Cost Share Agreement, which were used by the Company, in part, to make payments to certain other contractors for work under the Cost Share Agreement. The payments to these other contractors, all made in November 2024 and on General Atomics' behalf, totaled to $4,746. The Company and General Atomics expect to enter into an amended Cost Share Agreement in the second half of 2025 to cover the non-federal portion of the DoE approved project budget of $53,600.

Inclusive of all amounts incurred since project inception, a total of $57,488 has been expended on the Demonstration Plant through June 30, 2025.

**5. WYOMING ENERGY AUTHORITY GRANT** 

In June 2023, the Company, and the WEA entered into a Funding Agreement (the "WEA Funding Agreement") pursuant to which the WEA agreed to fund, subject to certain conditions, a $4,400 grant to the Company, the proceeds of which are to be used for the Demonstration Plant. Pursuant to the WEA Funding Agreement, the grant is to be paid upon the WEA's receipt of invoices from the Company detailing its actual expenses relating to the Demonstration Plant (half of which funds will be allocated to two milestone periods during the development process), less a 10% retainer, the payment of which is conditioned upon the WEA's receipt, following the commencement of the Demonstration Plant's operations, of an invoice and the Company's final executive summary report in a form to be approved by the WEA. Pursuant to the WEA Funding Agreement, the funding for the Demonstration Plant will be provided to the WEA from the Energy Resources Council (the "ERC") and is further conditioned upon the availability of government funds that are appropriated or allocated for the payment of the grant and which may be limited for any reason, including congressional, legislative, gubernatorial, or administration action.

The WEA Funding Agreement will terminate when the funding has been fully disbursed, but no later than June 30, 2026, unless terminated sooner by either party in accordance with the terms of the WEA Funding Agreement. The WEA Funding Agreement may be terminated (i) by either party if the WEA does not receive the requested funding from the ERC or if the grant funds are not allocated or available for the continued performance of the WEA Funding Agreement, or (ii) by the WEA immediately for cause if the Company fails to perform in accordance with the terms of the WEA Funding Agreement.

**As of December 31, 2023, the Company had met the conditions allowing for the invoicing of $2,000 of the $4,400 WEA grant total. This $2,000 was subsequently received on January 31, 2024. By September 30, 2024, the Company had met the conditions allowing for the invoicing of an additional $2,000, which was subsequently received in November 2024. The remaining $400 of the $4,400 grant total, which is conditioned on the achievement of other, future milestones, will be invoiced to the WEA once those final milestones have been achieved, which are currently expected to occur in early 2026.**

6. LEASES

The Company accounts for leases in accordance with ASC 842 – *Leases.* This accounting standard requires all lessees to record the impact of leasing contracts on the balance sheet as a right to use asset and corresponding liability. This is measured by taking the present value of the remaining lease payments over the lease term and recording a right to use asset and corresponding lease obligation for lease payments. Rent expense is realized on a straight-line basis and the lease obligation is amortized based on the effective interest method. The amounts recognized reflect the present value of the remaining lease payments for all leases that have a lease term greater than 12 months. The discount rate used is an estimate of the Company's incremental borrowing rate based on information available at lease commencement in determining the present value of lease payments.

**June 30, 2025**

*(all amounts stated in thousands of U.S. dollars except share and per share amounts)*

*(unaudited)*

In considering the lease asset value, the Company considers fixed or variable payment terms, prepayments, and options to extend, terminate or purchase. Renewal, termination, or purchase options affect the lease term used for determining lease asset value only if the option is reasonably certain to be exercised.

Effective September 21, 2021, the Company entered into a lease agreement (the "Property Lease") for real property, including land and buildings in Upton, Wyoming for the Demonstration Plant. The Property Lease is a 12-month lease with annual renewal terms, which at the Company's option can be renewed for as long as the facility is needed. In June 2025, the Property Lease was renewed, extending the termination date to September 30, 2026. The Property Lease, which is classified as an operating lease, generally provides for base rent, and requires the Company to pay all insurance, personal property taxes on any structure or improvements made by the Company and other maintenance costs. The Property Lease provides for an annual cost of living adjustment, but contains no residual value guarantees or restrictive covenants. Pursuant to the Property Lease, the Company is obligated to remove certain Company completed property improvements, though those items requiring removal, if any, will be confirmed with the lessor prior to the termination of the Property Lease.

On May 14, 2024, the Company entered into a second lease agreement for modular office units for use at its Demonstration Plant site in Upton, Wyoming (the "Office Lease"). The Office Lease, which was for an initial 12-month term and provides for monthly extension options thereafter, is classified as an operating lease, and generally provides for base rent, and requires the Company to pay all insurance, property taxes and other applicable costs, including the transportation charges to return the units to their original point of origin in an amount not to exceed $7.

For purposes of the following table, payments under the Property Lease and Office Lease are assumed to run through September 30, 2026 and December 31, 2025, respectively. If the completion of the Demonstration Plant operations dictates further extensions beyond these dates, the Company may seek to extend the term of one or both lease agreements accordingly.

Total future lease payments under the Company's leases as of June 30, 2025 are as follows:

---

| | |
|:---|:---|
| 2025 | $105 |
| 2026 | 96 |
| Total lease payments | 201 |
| Less interest | (11) |
| Present value of lease payments<sup>(1)</sup> | $190 |

---

<sup>(1)</sup> As of June 30, 2025, $149 was included in current liabilities and $41 was included in non-current liabilities.

For the six months ended June 30, 2025, $80 was included in operating cash flows for amounts paid for operating leases.

As of June 30, 2025 the weighted average lease term for the Company's operating leases was one year (including expected renewal options) and the weighted average discount rate was estimated at 12%.

**7. SHAREHOLDERS' EQUITY**

#### Stock-based compensation
As of June 30, 2025, the Company had 2,685,000 issued and outstanding stock options that were issued under the 10% Rolling Stock Option Plan, as amended and restated (the "2011 Plan") and 1,020,000 issued and outstanding stock options that were issued under its 2022 Equity Incentive Plan (the "2022 Plan").

**8. COMMITMENTS AND CONTINGENCIES**

#### Potential environmental contingency
The Company's exploration and development activities are subject to various federal and state laws and regulations governing the protection of the environment. These laws and regulations are continually changing and generally have become more restrictive. The Company conducts its operations to protect public health and the environment and believes that its operations are materially in compliance with all applicable laws and regulations. The Company has made, and expects to make in the future, expenditures to comply

with such laws and regulations. The ultimate amount of reclamation and other future site-restoration costs to be incurred for existing mining interests is uncertain and may exceed the Company's estimates of these costs, which at June 30, 2025 and 2024 were estimated at $185 and $182, respectively.

#### Contract commitment – related party
Pursuant to the Cost Share Agreement between the Company and General Atomics, as extended and as expected to be amended in the second half of 2025, and as discussed in Note 4, the Company has agreed to assume and pay for certain allowable costs under the DoE-approved Demonstration Plant budget incurred by General Atomics and the other consortium members for the design, construction, operation, and decommissioning of the Demonstration Plant.

**9. GEOGRAPHIC AND SEGMENT INFORMATION**

The Company has one reportable operating segment. We seek to advance and develop our Bear Lodge REE Project, which could lead to the future production of REEs or other value-adding strategic transactions. These activities are currently focused in the State of Wyoming. We reported no revenues during the three and six months ended June 30, 2025 and 2024. The operating segment's chief decision maker is the Company's Chief Executive Officer ("CEO").

Our actual results, performance, or achievements may differ materially from those anticipated in these forward-looking statements as a result of many factors, including, but not limited to, those set forth elsewhere in this report. See "Cautionary Note Regarding Forward-Looking Statements."

#### All currency amounts are expressed in thousands of U.S. dollars, unless otherwise noted.

#### Overview and Outlook
Our primary focus has been and continues to be the engineering, permitting, licensing, construction, and operation of the Demonstration Plant. If successful, the Demonstration Plant will show that our proprietary extraction technology is able to process and separate certain REEs from sample materials extracted from our Bear Lodge REE Project in a more efficient and economical manner than traditional REE processing methods and will serve as a precursor to inform the design and estimated cost for a future full-scale production facility.

In September 2024, the DoE issued its final Project Continuation Notice, confirming the Demonstration Plant's readiness for operations. This notice, along with the NRC's approval of operations received in October 2024, cleared the path for operations of the Demonstration Plant to formally commence, with operations to process and separate the REE from the already stockpiled high-grade sample materials from the Bear Lodge REE Project to follow the completion of construction and pre-operation activities. During the first half of 2025, the Company, along with the other consortium members, continued their work on the Demonstration Plant project, and this work is expected to continue until the completion of the project's operations.

During the first half of 2025, several design and equipment issues were identified during the Demonstration Plant's equipment testing phase, which followed the completion of construction activities. As a result of these issues, an as-built design review was commenced in April 2025. The Company now expects plant commissioning to start in late 2025 and commencement of plant operations to begin in the first quarter of 2026. During the production phase, the Demonstration Plant is expected to produce up to 10 tons of NdPr oxide.

In June 2023, the Company entered into the WEA Funding Agreement for its previously announced award of a $4,400 grant from the WEA to be used toward the advancement of the Demonstration Plant. This award, along with funds contributed by the Company and the DoE, is being used to fund the Demonstration Plant's construction and operating costs. As of December 31, 2023, the Company had met the conditions allowing for the invoicing of $2,000 of the $4,400 WEA grant total. This $2,000 was subsequently received on January 31, 2024. By September 30, 2024, the Company had met the conditions allowing for the invoicing of an additional $2,000, which was subsequently received in November 2024. The remaining $400 of the $4,400 grant total, which is conditioned on the achievement of other, future milestones, will be invoiced to the WEA once those final milestones have been achieved, which are currently expected to occur in early 2026.

Since inception, the General Atomics-led consortium has seen increases in the Demonstration Plant project costs, including final equipment costs, due to, among other factors, inflation. As a result of these cost pressures, General Atomics, on behalf of the consortium, submitted to the DoE an updated Demonstration Plant construction and operations budget of approximately $53,600, which is approximately 22% higher than the original budget of approximately $43,800. In response, the DoE pledged an additional commitment of $2,400 to help fund a portion of this budget increase, with the balance to be funded by the Company, including any amounts in excess of the $53,600 revised DoE approved budget total, now estimated to be in excess of $66,000.

To fund the Company's share of these cost increases, in March 2024, the Company completed a rights offering (the "2024 Rights Offering") for gross proceeds of approximately $35,800, in which each holder of the Company's common shares as of the record date of December 15, 2023, was eligible to participate. The proceeds from the 2024 Rights Offering are being used to progress the Company's

[**Table of Contents**](#TOC)

business strategy, which includes the rework of the Demonstration Plant and its operation for a period of time sufficient to provide the information to support a commercialization decision, as well as for other general corporate purposes.

Even with these funds and the expected receipt of the remaining WEA grant monies and DoE funds, the Company will still require substantial additional funds for the permitting, development, and build-out of the Bear Lodge REE Project. As a result, the Company commenced discussions with the Export-Import Bank of the United States ("EXIM Bank") as a potential source of funds for the Bear Lodge REE Project's development. In March 2025, the Company received a non-binding Letter of Interest from the EXIM Bank to provide debt financing of up to $553,000 for the Bear Lodge REE Project's development. If pursued further by the Company through a loan application, and that application is approved, these funds could support the permitting, engineering, design, and construction of the Bear Lodge REE Project. However, there can be no assurance these funds will be pursued or, if pursued, approved by the EXIM Bank.

Ultimately, in the event the Company cannot secure additional financial resources, or complete a strategic transaction in the longer term, the Company may need to curtail or suspend its operational plans regarding the Bear Lodge REE Project or other initiatives, or potentially liquidate its business interests, and investors may lose all or part of their investment.

*Current External Factors Impacting our Business*

During the first half of 2025, we continued to monitor the general U.S. political climate and actions taken by the U.S. government to secure a domestic rare earth supply chain. Due to the dominance of China over the REE supply chain, the U.S. federal government has issued several Presidential Executive Orders, under both the Biden Administration and the first and second Trump Administrations, to encourage and support the establishment of a domestic REE supply chain and to strengthen the defense industrial base with respect to critical minerals, including REEs.

On January 20, 2025, President Trump issued the "Unleashing American Energy" Executive Order, which included: (1) several urgent critical mineral and rare earth directives, including the immediate review of all agency actions that potentially burden the development of domestic energy resources with particular attention to critical minerals; (2) directing the Secretary of Energy to ensure that critical mineral projects, including the processing of critical minerals, receive consideration for federal support; (3) directing the Secretary of Defense to consider the needs of the U.S. in supplying and maintaining the national defense stockpile to provide a robust supply of critical minerals; and (4) establishing the U.S. position as the leading producer and processor of rare earth minerals, which will create jobs and prosperity at home, strengthen supply chains for the U.S. and its allies, and reduce the global influence of malign and adversarial states.

In March 2025, President Trump issued the "Immediate Measures to Increase American Mineral Production" Executive Order. In this Executive Order, President Trump directed the federal agencies, including the EXIM Bank, to unlock the permitting, funding and issuance of off-take agreements for critical minerals, including rare earths. The Executive Order includes near-term actions to be determined and implemented by the federal agencies to fast-track permits, mobilize capital for mineral producers and create off-take agreements for the strategic stockpiling of minerals critical to the United States' defense, technology and energy.

Additionally, in early 2025, the Trump Administration announced several potential new and/or increased tariffs and other trade restrictions on imports to the United States. The impact of these tariffs and trade restrictions is currently unknown and could have an impact on the REE supply chain and/or our business operations. In response to the tariffs and trade restrictions imposed by the Trump and previous Administrations, China, in December 2023, announced it had banned the export of technology to make rare earth magnets, adding to its previous export ban of critical material extraction and separation technology. In December 2024, China further banned the export of certain critical minerals, including gallium, germanium, and antimony, which have widespread military applications. In February 2025, China expanded its export licensing requirements to include five additional minerals: tungsten, indium, bismuth, tellurium, and molybdenum. In April 2025, China imposed additional export restrictions on REEs, including both raw materials and processed products such as permanent magnets. As U.S.-China trade negotiations continued, the April 2025 restrictions were lifted in part, however, a Chinese rare earth licensing system remains in place, which controls the export of rare earths and technology relating to rare earths.

In addition, the impacts of the COVID-19 pandemic and other external influences (such as the Russia/Ukraine war, conflicts in the Middle East, and tariffs on certain critical mineral exports from China) have further focused the U.S. government on the importance of implementing secure domestic supply chains, including for REEs.

#### Results of Operations

#### Summary
For the three and six months ended June 30, 2025, we experienced net losses of $1,180 ($0.00 per share) and $3,575 ($0.01 per share), respectively, compared with net losses of $6,179 ($0.01 per share) and $9,805 ($0.02 per share) for the three and six months ended June 30, 2024, respectively. See our discussion below for the primary drivers of these changes. As an exploration stage company, we had no properties in production and generated no revenues during either period.

#### Exploration and Evaluation
Our exploration and evaluation costs decreased by $5,003 over the comparative three-month period, decreasing from $5,821 for the three months ended June 30, 2024 to $818 for the three months ended June 30, 2025, and by $6,029 over the comparative six-month period, decreasing from $8,724 for the six months ended June 30, 2024 to $2,695 for the six months ended June 30, 2025. These decreases were largely attributable to the activities associated with our Demonstration Plant as activities shifted from equipment acquisitions and installation during 2024 to final testing and shakedown activities in 2025. See Note 4 to the Consolidated Financial Statements for a discussion of the Cost Share Agreement.

#### Corporate Administration
Our corporate administrative costs remained relatively constant at $568 and $623 for the three months ended June 30, 2025 and 2024, respectively, and $1,318 and $1,322 for the six months ended June 30, 2025 and 2024, respectively. The majority of these expenses relate to costs associated with our public company compliance and reporting obligations.

#### Interest Income
***Our interest income decreased by $110 over the comparative three-month periods, decreasing from $371 for the three months ended June 30, 2024 to $261 for the three months ended June 30, 2025 while increasing by $93 over the comparative six-month periods, increasing from $452 for the six months ended June 30, 2024 to $545 for the six months ended June 30, 2025. These changes were largely attributable to our 2024 Rights Offering, which closed in March 2024, and its impact on our excess cash balances available for investment pre- and post-closing.***

#### Accretion Expense
For the three and six months ended June 30, 2025, we recorded accretion expense of nil (in each period) compared to $71 and $142 for the three and six months ended June 30, 2024, respectively, with the accretion expense recorded during 2024 being related to the Company's option to repurchase approximately 640 acres (257 hectares) of real property in Wyoming. With the Company's repurchase of this land in October 2024, the Company discontinued its recording of accretion expense and will not incur further accretion expense in future periods related to this repurchase option.

#### Financial Position, Liquidity and Capital Resources
Operating Activities

Net cash used in operating activities was $3,537 for the six months ended June 30, 2025, compared with $8,287 for the same period in 2024. This reduction of $4,750, partially offset by the collection in 2024 of $2,000 in WEA grant funds, was largely attributable to the decrease in our exploration and evaluation expenditures as activities shifted from Demonstration Plant equipment acquisitions and installation during 2024 to final testing and shakedown activities in 2025. Absent the $2,000 in WEA grant offset funds, net cash used in operating activities for the six months ended June 30, 2024 would have been $10,287.

Investing Activities

Net cash used in investing activities of $142 and $52 for the six months ended June 30, 2025 and 2024, respectively, were for the purchase of equipment. The 2024 total was partially offset by $12 in proceeds from the sale of equipment.

[**Table of Contents**](#TOC)

Financing Activities

Net cash provided by financing activities of $35,286 for the six months ended June 30, 2024 stemmed from the receipt of the net proceeds from the 2024 Rights Offering. There were no similar transactions during the six months ended June 30, 2025.

Financial Position, Liquidity and Capital Resources

At June 30, 2025, we had a working capital balance of $21,142 which was a decrease of $3,679 from our December 31, 2024 working capital balance of $24,821. This decrease was largely the result of the reduction in our cash and cash equivalents balance, which decreased by $3,682 from $26,732 at December 31, 2024 to $23,050 at June 30, 2025.

In June 2023, the Company entered into the WEA Funding Agreement for its previously announced award of a $4,400 grant from the WEA to be used toward the advancement of the Demonstration Plant. Following the achievement of the first milestone under the WEA Funding Agreement, the Company received in January 2024 the first $2,000 of the $4,400 grant. In September 2024, a second funding request of $2,000 was submitted to the WEA with the achievement of the second milestone under the WEA Funding Agreement. The collection of this second $2,000 tranche was received in November 2024, with the remainder, or the $400 retainer, forecasted for collection in early 2026.

Due to inflationary cost pressures on labor, equipment, and consumables, as well as cost increases associated with certain optimized plant engineering and design parameters, General Atomics, on behalf of the consortium, submitted to the DoE an updated Demonstration Plant project budget of approximately $53,600, which is approximately 22% higher than the original budget of approximately $43,800. In response, the DoE pledged an additional commitment of $2,400 (increasing its total commitment to approximately $24,200) in September 2024 to help fund a portion of this budget increase, with the balance to be funded by the Company, including any amounts in excess of the $53,600 revised budget total, now estimated to be in excess of $66,000. Through June 30, 2025, the DoE has paid a total of approximately $20,500 towards its commitment of approximately $24,200, leaving a balance of approximately $3,700 to be invoiced and collected from the DoE under the current cost share award.

During the first half of 2025, several design and equipment issues were identified during the Demonstration Plant's equipment testing phase, which followed the completion of construction activities. As a result of these issues, an as-built design review was commenced in April 2025. The Company now expects plant commissioning to start in late 2025 and commencement of plant operations to begin in the first quarter of 2026. As of June 30, 2025, the scope of rework activities was still under review.

The funds raised by the Company in the 2024 Rights Offering are expected to support the operations of the Demonstration Plant for a sufficient period of time to gather the information necessary for a commercialization decision. However, even with these funds and the expected receipt of the remaining WEA grant monies and DoE funds, the Company will still require substantial additional funds to complete the permitting and licensing, and ultimate construction and operation of a commercial mine and plant for the Bear Lodge REE Project. Ultimately, in the event the Company cannot secure additional financial resources, or complete a strategic transaction in the longer term, the Company may need to curtail or suspend its operational plans regarding the Bear Lodge REE Project or other initiatives, or potentially liquidate its business interests, and investors may lose all or part of their investment.
