**RARE ELEMENT RESOURCES LTD.**

P.O. Box 271049

Littleton, Colorado 80127

Dear Shareholder:

Over the last year, we've seen heightened worldwide attention to the rare earth element ("REE") supply chain. With China's monopoly becoming a political weapon in the geopolitical landscape, with resulting tariff assessments including on rare earths, the importance of REEs in evolving technologies, especially those critical to United States national security needs, has reached the highest levels. These market dynamics culminated in a Presidential Executive Order in March 2025 calling for swift and decisive action to secure America's rare earth supply. Today more than ever before, America and its allies are seeking a secure, diversified REE supply chain, from mine to magnets. Rare Element Resources Ltd. ("we", "us", "our" or the "Company") has successfully positioned itself as one of the future sources of separated domestic rare earths.

The Company has completed construction of its demonstration-scale REE separation and extraction plant in Upton, Wyoming, that will incorporate the Company's proprietary REE recovery and separation technology (the "Demonstration Plant"). While construction is now complete, a review of the Demonstration Plant is underway to identify necessary upgrades or rework required for safe and efficient operations. As a first-of-its-kind facility, the final design aims to ensure safe and efficient production of high-purity neodymium and praseodymium ("Nd/Pr") such that the Company obtains reliable operational and economic data for use in the planning and engineering of a future Nd/Pr commercial plant. Commissioning of the Demonstration Plant is expected to start in late 2025, processing stockpiled material from the Bear Lodge Rare Earth Element Project (the "Bear Lodge REE Project" or the "Project"), with operations planned for up to ten months after commissioning.

As of September 2024, the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy (the "DOE") awarded the Company approximately $24.2 million to support the engineering, construction, and operation of the Demonstration Plant. As of July 2025, the Company is in ongoing discussions with the DOE regarding potential additional cost-share support. Combined with a $4.4 million grant from the Wyoming Energy Authority, approximately 40% of the Demonstration Plant's anticipated costs are expected to be funded through federal and state sources.

In March 2024, we released updated Technical Report Summary ("TRS") for the Bull Hill deposit at the Bear Lodge REE Project, detailing approximately 6 million tonnes of measured and indicated mineral resource at an average total rare earth oxide grade of approximately 4%. This mineral resource supports a small-footprint operation with an estimated 30-year mine life. The TRS also identified additional targets for potential expansion. In early 2025, we began updating environmental background data to support the restart of permitting.

Additionally, in March 2025, we received a letter of interest from the Export-Import Bank of the United States to provide up to $553 million in debt financing for the Bear Lodge REE Project, creating a potential path to Project development capital to support permitting, engineering design, and construction of the Project as the Company advances the Project's development.

In 2025, we are focused on successful progress at the Demonstration Plant such that operations can commence as soon as practicable. At the same time, we are exploring further advancement opportunities for the Demonstration Plant, following our Nd/Pr separation program. We are seeking additional funding support from the DOE, Department of Defense and other federal and state programs to advance these initiatives. The Demonstration Plant advancements could lead to ongoing operations for separating heavy rare earth elements ("HREE"), particularly dysprosium and terbium, which are of particular interest to the defense industry. Further, the advancements could lead to processing third-party feed sources utilizing our proprietary REE processing and separation technology. With the planned investment of over $66 million, we believe the Demonstration Plant's size and capacity could support an ongoing HREE commercial operation longer term.

Given our continued progress in 2024 and the first half of 2025, we believe that the Company is well positioned to be able to make informed full-scale commercialization decisions in 2026 as we move toward becoming a secure domestic supplier of critical REEs.

At the annual meeting of shareholders, the Board of Directors recommends that you vote affirmatively:

● to elect the named director nominees to our Board of Directors;

● to appoint Haynie & Company to serve as the independent registered public accounting firm of the Company until the next annual meeting of shareholders of the Company at an amount of remuneration to be fixed by the directors; and

● to transact such other business that properly comes before the annual meeting or any adjournment or postponement thereof.

**Your affirmative** **vote will continue positioning the Company for future success.**

**We encourage you to attend this year's annual meeting of shareholders. We will host the annual meeting of shareholders in-person at the offices of General Atomics affiliates, 7800 East Dorado Place, 2nd Floor, Greenwood Village, Colorado 80111 on Tuesday, September 9, 2025 at 2:00 p.m. (Mountain Daylight Time).**

We intend to hold our annual meeting of shareholders in person. Registered holders can vote their shares in advance of the meeting by Internet, toll-free telephone, or mail. If your common shares are held in the name of a broker, bank or other holder of record, follow the voting instructions you receive from the holder of record describing how to vote your common shares. Shareholders may also vote in person at the meeting. If changes to our current plan to hold an in-person meeting become advisable due to public health or other concerns, we will disclose the updated plan on our proxy website (*http://www.proxyvote.com*) and our company website (*www.rarelementresources.com*). We encourage you to check one of these websites prior to the meeting if you plan to attend in person.

**It is important that you retain a copy of the control number found on the proxy card, voting instruction form or notice of meeting, as such number will be required in order for shareholders to dial in to listen to the meeting.**

Only shareholders of record at the close of business on July 16, 2025 are entitled to notice of, and to vote at, the annual meeting.

An undated but executed proxy will be deemed to be dated the date of the mailing of the Proxy by the Company or its agent.

If you received a paper copy of the proxy materials by mail and wish to vote your proxy by mail, mark your vote on the enclosed Proxy card; then follow the directions on the card. To vote your Proxy using the Internet or by telephone, see the instructions set forth on the Notice of Meeting included with this Circular or the Notice of Internet Availability of Proxy Materials mailed to our shareholders on or about July 28, 2025.

up to and including 4:59 p.m. (Mountain Daylight Time) on the last business day before the day set for the Meeting;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) signing and dating a written notice of revocation and delivering it to the registered office of the Company

present in person.

**Provisions Relating to Voting of Proxies**

The common shares of the Company (the "Common Shares") represented by Proxy in the enclosed form will be voted or withheld from voting by the designated proxyholder in accordance with the direction of the registered shareholder appointing him, her or it. **If there is no direction by the registered shareholder, those Common Shares for which management and the Board are the designated proxyholders will be voted in accordance with the Board's recommendation for such matter or matters, as described under each such proposal in this Circular.**

**Exercise of Discretion by Proxyholders**

The Proxy gives the person named in it the discretion to vote as such person sees fit on any amendments or variations to matters identified in the Notice of Meeting, or any other matters which may properly come before the Meeting, subject to any limitation imposed by applicable law. At the time of printing of this Circular, management of the Company knows of no other matters which may come before the Meeting other than those referred to in the Notice of Meeting. If any amendment or variation or other matter comes before the Meeting, the persons named in the Proxy will vote in accordance with their best judgment on such amendment, variation or other matter, subject to any limitation imposed by applicable law.

**Non-Registered Holders**

The information set out in this section is important to many shareholders, as a substantial number of shareholders do not hold their Common Shares in their own name.

Only registered shareholders or duly appointed proxyholders are permitted to vote at the Meeting. Most shareholders of the Company are "non-registered" shareholders because the Common Shares they own are not registered in their names but are instead registered in the name of the brokerage firm, bank or trust company through which they purchased the Common Shares. A person is not a registered shareholder (a "Non-Registered Holder") in respect of Common Shares which are held either (a) in the name of an intermediary (an "Intermediary") that the Non-Registered Holder deals with in respect of the Common Shares (Intermediaries include, among others, banks, trust companies, securities dealers or brokers and trustees or administrators of self-administered registered retirement savings plans, registered retirement income funds, registered education savings plans and similar plans); or (b) in the name of a clearing agency (such as CDS Clearing and Depository Services Inc., or CDS, in Canada and the Depository Trust Company, or DTC, in the United States), of which the Intermediary is a participant.

The Company has elected to use the notice and access rules ("Notice and Access") established by U.S. federal securities laws in respect of the provision of the Notice of Meeting, this Circular and the Proxy (collectively, the "Meeting Materials") to its registered shareholders and Non-Registered Holders. The Notice and Access rules allow an issuer to post electronic versions of its proxy-related materials, rather than mailing paper copies to its shareholders, and provide instructions on how shareholders may access the Meeting Materials electronically or request a paper copy of the Meeting Materials.

Non-Registered Holders who have not objected to their Intermediary disclosing certain ownership information about themselves to the Company are referred to as Non-Objecting Beneficial Owners, or "NOBOs." Those Non-Registered Holders who have objected to their Intermediary disclosing to the Company ownership information about themselves are referred to as Objecting Beneficial Owners, or "OBOs." The Company has elected to send the applicable Meeting Materials prescribed by the Notice and Access rules directly to the NOBOs, and indirectly through Intermediaries to the OBOs. The Intermediaries (or their service companies) are responsible for forwarding the applicable Meeting Materials to each OBO (including the costs associated therewith), unless the OBO has waived the right to receive them.

Intermediaries will frequently use service companies to forward the meeting materials to the OBOs. Generally, an OBO who has not waived the right to receive meeting materials will either:

&nbsp;&nbsp;&nbsp;&nbsp;(a) be given a form of proxy which has already been signed by the Intermediary (typically by a facsimile,
stamped signature), which is restricted as to the number of Common Shares beneficially owned by the OBO and must be completed, but not
signed, by the OBO and deposited with Computershare, the Company's transfer agent; or

&nbsp;&nbsp;&nbsp;&nbsp;(b) more typically, be given a voting instruction form ("VIF") which is not signed by the Intermediary,
and which, when properly completed and signed by the OBO and returned to the Intermediary or its service company, will constitute voting
instructions which the Intermediary must follow.

If you are a Non-Registered Holder, and the Company or its agent has sent the applicable Meeting Materials to you, your name and address and information about your holdings of securities have been obtained in accordance with applicable securities regulatory requirements from the Intermediary holding securities on your behalf. By choosing to send these materials to you directly, the Company (and not the Intermediary holding securities on your behalf) has assumed responsibility for (i) delivering these materials to you and (ii) executing your proper VIF. Please return your VIF as specified in the request for voting instruction.

The applicable Meeting Materials sent to NOBOs who have not waived the right to receive Meeting Materials are accompanied by a VIF, instead of a Proxy. By returning the VIF in accordance with the instructions noted on it, a NOBO is able to instruct the voting of his, her or its Common Shares.

VIFs, whether provided by the Company or by an Intermediary, should be completed and returned in accordance with the specific instructions noted on the VIF. The purpose of this procedure is to permit Non-Registered Holders to direct the voting of the Common Shares which they beneficially own. Should a Non-Registered Holder who receives a VIF wish to attend the Meeting or have someone else attend on his, her or its behalf, the Non-Registered Holder may request a legal proxy as set forth in the VIF, which will grant the Non-Registered Holder, or his, her or its nominee, the right to attend and vote at the Meeting.

**Please return your voting instructions as specified in the VIF. Non-Registered Holders should carefully follow the instructions set out in the VIF, including those regarding when and where the VIF is to be delivered.**

**Financial Statements**

The audited financial statements of the Company for the fiscal year ended December 31, 2024, together with the independent registered public accounting firm's report on those statements (the "Financial Statements"), are included in these proxy materials and will be presented to the shareholders at the Meeting.

**A copy of the Company's Annual Report on Form 10-K, including financial statements, required to be filed with the U.S. Securities and Exchange Commission (the "SEC") pursuant to the U.S. Securities Exchange Act of 1934, as amended (the "Exchange Act"), for the fiscal year ended December 31, 2024 may be obtained by any registered or beneficial owner of the Common Shares, determined as of** **July 16, 2025, free of charge on the Company's website (*www.rareelementresources.com*) or by written request to:**

**VOTING SECURITIES AND PRINCIPAL HOLDERS OF VOTING SECURITIES**

As at July 16, 2025, the Company's authorized capital consisted of an unlimited number of Common Shares without par value of which 516,134,712 Common Shares are issued and outstanding. Each Common Share in the capital of the Company carries the right to one vote. Voting rights are not cumulative.

The Board has fixed the close of business on July 16, 2025 as the record date for the purpose of determining the shareholders entitled to receive notice of and to vote at the Meeting, but failure of any shareholder to receive notice of the Meeting does not deprive such shareholder of the entitlement to vote at the Meeting. Only shareholders of record at the close of business on July 16, 2025 who either personally attend the Meeting or who have completed and delivered a Proxy in the manner and subject to the provisions described herein will be entitled to vote or to have his, her or its Common Shares voted at the Meeting.

Shareholders who wish to be represented by proxy at the Meeting must deliver their Proxies at the place and within the time set forth in the notes to the Proxy in order to entitle the person appointed by the Proxy to attend and vote.

**Broker Non-Votes, Abstentions and Voting Requirements**

Brokers and other Intermediaries holding Common Shares in street name for their customers are required to vote the Common Shares in the manner directed by their clients. Under the *Business Corporations Act* (British Columbia) (the "BCA"), brokers and other Intermediaries are not entitled to vote shares held in street name for their customers where they have not received written voting instructions from the Non-Registered Holders of those shares. Under applicable U.S. rules, brokers are prohibited from giving proxies to vote on non-routine matters (including, but not limited to, director elections) unless the beneficial owner of such shares has given voting instructions on the matter. The absence of a vote on a matter where the broker or other Intermediary has not received written voting instructions from a Non-Registered Holder is referred to as a "broker non-vote."

The directors must be elected by an affirmative vote of a plurality of the votes cast, either in person or by proxy, at the Meeting on the matter. Plurality voting means that the seven directors receiving the greatest number of "FOR" votes will be elected to the Board. Cumulative voting (i.e., a form of voting where shareholders are permitted to cast all of their aggregate votes for a single nominee) will not be permitted. Therefore, any Common Shares represented at the Meeting but not voted (whether by abstention, broker non-vote or otherwise) will have no impact on the election of directors.

The appointment of the independent registered public accounting firm requires an affirmative vote of a plurality of the votes cast, either in person or by proxy, at the Meeting on the matter. Therefore, any Common Shares represented at the Meeting but not voted (whether by abstention, broker non-vote or otherwise) will have no impact on the proposal to appoint the independent public accounting firm.

**Ownership of Common Shares by Certain Beneficial Owners**

The following table sets forth information (as of the date indicated) as to all persons or groups known to the Company to beneficially own, control or direct, directly or indirectly, 5% or more of the issued and outstanding Common Shares of the Company as of July 16, 2025:

**PROPOSAL NO. 1:**

**ELECTION OF DIRECTORS**

**Director and Director Nominee Experience and** **Qualifications**

The Board, through its Nominating, Corporate Governance and Compensation Committee (the "NCG&C Committee"), considers its size each year when it considers the number of directors to recommend to the shareholders for election at the annual meeting of shareholders, taking into account the number required to carry out the Board's duties effectively and to maintain a diversity of views and experience. The NCG&C Committee is comprised of one independent director and three non-independent directors.

The Board believes that, as a whole, it should possess a combination of skills, professional experience and diversity necessary to oversee the Company's business. In addition, the Board believes that there are certain attributes that every director should possess, as reflected in the Board's membership criteria (further described below). Accordingly, the Board and the NCG&C Committee consider the qualifications of director and director candidates individually and in the broader context of the Board's overall composition and the Company's current and future needs.

The NCG&C Committee reviews and makes recommendations regarding the composition and size of the Board in order to ensure that the Board has the requisite expertise, and its membership consists of persons with sufficiently diverse and independent backgrounds. Board membership criteria include items relating to ethics, integrity and values, sound business judgment, professional experience, industry knowledge, and diversity, including gender diversity, all in the context of an assessment of the perceived needs of the Board at that point in time. The Board, as a whole, should possess a variety of skills, occupational and personal backgrounds, experiences and perspectives necessary to oversee the Company's business. In addition, Board members generally should have relevant professional or technical skills or financial acumen that demonstrates an understanding of the financial and operational aspects of a rare earth exploration, development, mining, and processing company.

In evaluating director candidates and considering incumbent directors for re-nomination, the Board and the NCG&C Committee have not formulated any specific minimum qualifications, but, rather, consider a variety of factors. These include each nominee's independence, financial acumen, personal accomplishments, career specialization, and experience in light of the needs of the Company. For incumbent directors, the factors also include past performance on the Board. The Board determines the Chairman from among the Company's directors following the election of directors at the annual meeting of shareholders.

Pursuant to and subject to the terms and conditions of the Investment Agreement dated October 2, 2017 between the Company and Synchron (the "Investment Agreement"), as long as Synchron's fully diluted ownership in the Company is at least 33.0%, Synchron has the right to designate two directors for appointment or election to the Board, where the Board is comprised of six or seven directors following such appointment or election. David Roberts and Kenneth Mushinski were identified by Synchron as its two designees and served on the Board effective November 17, 2017. On October 16, 2019, the Company issued to Synchron an additional 24,175,000 Common Shares in connection with the exercise by Synchron of its common share purchase option dated October 2, 2017 (the "Option"). As a result, Synchron's ownership of outstanding Common Shares increased from approximately 33.5% to approximately 49.0%. With Synchron's exercise of the Option, Synchron obtained the right to designate one additional director for appointment or election to the Board. Barton S. Brundage, Synchron's additional designee, was elected to the Board at the annual meeting of shareholders held on December 18, 2019. As a result of Synchron's participation in the Company's rights offering completed in December 2021, Synchron's ownership of outstanding Common Shares increased from approximately 49.0% to approximately 54.8%. Ms. Champine was appointed to the Board on March 31, 2022, replacing Mr. Ken Mushinski, who had served as a director designee of Synchron since November 17, 2017. Then, as a result of Synchron's participation in a subsequent rights offering completed in March 2024, Synchron's ownership of outstanding Common Shares increased from approximately 54.8% to approximately 70.6%. On April 4, 2024, Mr. Roberts retired and resigned from the Board, and Craig S. Bartels was appointed to the Board to replace Mr. Roberts as a director designee of Synchron.

Seven directors are to be elected at the Meeting, representing no change in Board size from the current Board. Each Board member will serve until the next annual general meeting of shareholders or until his or her successor is duly elected or appointed. All incumbent directors will be standing for re-election at the Meeting.

Each of the Board and the NCG&C Committee proposes to nominate the persons listed below for election as directors of the Company. Executed Proxies received will, on any poll, be voted as directed, or, if there is no direction, will be voted "FOR" the nominees listed in this Circular. The Board and the NCG&C Committee do not contemplate that any of the nominees will be unable or unwilling to serve as a director.

The following table sets out the names and ages of the nominees for election as directors; their provinces or states and country of residence; the offices they hold within the Company, if any; their occupations; and the dates since which they have served as directors of the Company:

(2) Gerald W. Grandey was elected Chairman of the Board on June 10, 2015.

The following are brief biographies of the Company's directors for election to the Board:

*Gerald W. Grandey* has over 40 years of executive leadership in the mining industry. He is the former Chief Executive Officer of Canadian-based Cameco Corporation, one of the world's largest uranium producers. In 2010, Harvard Business Review recognized Mr. Grandey as being one of the Top 100 CEOs in the world because of the value created for shareholders during his tenure at Cameco. After 18 years with Cameco, he retired as Chief Executive Officer and as a director in 2011. Previously, he held senior executive positions with Concord Services and Energy Fuels Nuclear. Mr. Grandey was recognized in 2014 for leadership in the nuclear industry with the U.S. Nuclear Energy Institutes' William S. Lee Award; inducted into the Canadian Mining Hall of Fame in 2013; awarded the Canadian Nuclear Association's Ian McRae Award in 2012 for his work in advancing nuclear energy in Canada; and was nominated for the 2011 Oslo Business for Peace Award in recognition of his efforts to facilitate nuclear disarmament. He is Chairman Emeritus for the London-based World Nuclear Association, the former Chairman of the Colorado School of Mines Board of Governors and a former board member of Nutrien Ltd. (2018–2019), Potash Corporation of Saskatchewan (2011–2018), Cameco Corporation (1999–2011), Centerra Gold Inc. (2004–2010), Inmet Mining Corporation (2012–2013), Sandspring Resources Ltd.

He has a degree in geophysical engineering from the Colorado School of Mines and a law degree from Northwestern University.

Mr. Grandey has extensive, high-level executive leadership experience in the mining industry, as well as experience and education in geophysical engineering. He brings to the Board key leadership, technical and related market expertise. Accordingly, the Board believes that Mr. Grandey should be re-elected to serve on the Board.

*Craig S. Bartels* has over 50 years of experience in the hydrocarbon, mineral extraction and processing industries and has played a leadership role in developing some of the key technology used globally to optimize In Situ Recovery (ISR) of uranium. He has served as the President and Chief Executive Officer of General Atomics Uranium Resources LLC since May 2024 and previously served as its Senior Vice President and Chief Operating Officer (November 2022–May 2024), which owns the stock of several General Atomics affiliated uranium companies. These affiliates include Rio Grande Resources Corporation and Nuclear Fuels Corporation, which have uranium properties in the United States and market uranium worldwide; Baywood Holdings Inc., which owns the Australian uranium mining and exploration companies Heathgate Resources Pty Ltd ("Heathgate") and Quasar Resources Pty Ltd; and General Atomics Energy Services, Inc., which is a partner in ConverDyn. Mr. Bartels was the President of Heathgate from June 2010 to October 2022, and he has served as a director of Heathgate since 2010. From December 2004 to June 2010, he served in various roles for Uranium Resources, Inc. and its subsidiaries, including as Senior Vice President of Technology (November 2008–June 2010), Vice President of Operations – In Situ for URI, Inc.

Mr. Bartels's background in the mineral extraction processing industries, experience in developing technology to optimize mineral recoveries, and executive experience in mining operations are valuable to the Board. Accordingly, the Board believes that Mr. Bartels should be elected to serve on the Board.

*Barton S. Brundage* has served since May 2021 as President of Cordillera Corporation ("Cordillera"), an affiliate of General Atomics and Synchron. In his current role and prior position of Executive Vice President (June 2007–May 2021), Mr. Brundage is and has been responsible for the day-to-day management of Cordillera's real estate operations in Colorado, Utah, and California. Since June 2007, he has served as Chairman of the board of directors of jetCenters, Inc. ("JCI"), an aviation fueling company and a subsidiary of Cordillera.

At Brundage & Company, he was employed in various capacities in the family-managed business, including Vice President, Senior Financial Analyst, and Analyst. He continues to serve as a member of Brundage & Company's board of directors (since 1980). Mr. Brundage received his Bachelor of Arts in Business Administration from Fort Lewis College and his Master of Business Administration from the University of Denver.

Mr. Brundage's extensive experience in financial resource acquisition and complex financial transactions, specifically in valuation and integration, brings to the Board additional depth in financial resource management. Accordingly, the Board believes that Mr. Brundage should be re-elected to serve on the Board.

*Nicole J. Champine* has served as Vice President and General Counsel of Cordillera (since July 2007) and as Vice President of Rio Grande Resources Corporation (since February 2025), both affiliates of General Atomics. Ms. Champine previously served as Cordillera's Legal Counsel (July 2001–July 2007).

Ms. Champine has a wide range of legal, corporate and technical expertise that she has applied in various industries, including real estate investment and development, civil and structural engineering and natural resources. Accordingly, the Board believes that Ms. Champine should be re-elected to serve on the Board.

From 1976 to 2022, he was a partner with the law firm of Rooney & Horiskey, which later became Hickey & Evans, LLP.

Mr. Hickey has extensive experience in representing energy and natural resource projects before regulatory agencies and state and federal courts.

Due to his extensive background in corporate development, sales, and marketing, Mr. Mushinski is uniquely positioned to assist the Board in identifying strategic partners and customers for the Company's products. He additionally contributes his vast experience in corporate asset management, including finance, tax, contracting and legal. Mr. Mushinski's experience in the minerals industry, domestically and internationally, provides the Company with valued insights on permitting and operations plans in the region. Accordingly, the Board believes that Mr. Mushinski should be elected to serve on the Board.

*Pamela L. Saxton* is an experienced mining company executive and director. She has served as a director and the Audit Committee Chair of Bunker Hill Mining Corp. since October 2020. Previously, she served as a director and the Audit Committee Chair of Timberline Resources Corporation (May 2021–August 2024) and Pershing Gold Corporation (November 2017–April 2019), as a director of Aquila Resources Inc. (June 2019–December 2021), and on the North American Advisory Board of Damstra Technology–Damstra Holdings Limited (February 2021–October 2022). As an executive, she served as the Executive Vice President and Chief Financial Officer of Thompson Creek Metals Company (August 2008–October 2016) and as the Chief Financial Officer of NewWest Gold Corporation (April 2006–December 2007). Having started her professional life working as an auditor at Arthur Andersen in Denver, Colorado, her career has included senior finance appointments in the American natural resources industry, including serving as the Vice President of Finance for Franco-Nevada Corporation's U.S. operations.

Ms. Saxton's qualifications to serve as a director include her knowledge of and long-standing executive experience in the mining industry, her experience in finance, accounting and auditing matters, and prior board experience. Accordingly, the Board believes that Ms. Saxton should be elected to serve on the Board.

**Executive Committee**

The Company does not currently have an executive committee of its Board.

**Director Independence**

The Board reviewed and determined independence under National Instrument 58-101 – *Disclosure of Corporate Governance Practices* ("NI 58-101") of each current director and director nominee. In making its independence determination, the Board considered the circumstances described below.

The Board determined that Mr. Mushinski is not independent based upon his position as an executive officer of the Company. The Board determined that Ms. Champine and Messrs. Brundage and Bartels are not independent based upon each person's employment with an affiliate of Synchron, the Company's majority shareholder. The Board determined that Mr. Hickey is not independent based upon his and his former law firm's work providing legal services to General Atomics (an affiliate of Synchron) and certain of its affiliates, and his work as a consultant to a subsidiary of the Company.

The Board has concluded that Mr. Grandey and Ms. Saxton are independent. As a result of these analyses, the Board has determined that the proposed seven-member Board would not be comprised of a majority of independent directors. Notwithstanding the above, the Board will carry out its duties under the stewardship of the independent Chairman of the Board, namely Mr. Grandey, whose role and responsibilities include overseeing the function and effectiveness of the Board and the exercise of independent supervision over management.

**Family Relationships**

There are no family relationships among any directors, officers or persons nominated to be directors of the Company.

**Arrangements between Officers and Directors**

No proposed director is being elected under any arrangement or understanding between the proposed director and any other person or company except for (i) the director and executive officer of the Company acting solely in such capacity (Mr. Mushinski) and (ii) the Synchron designees on the Board (Ms. Champine and Messrs. Brundage and Bartels) pursuant to the Investment Agreement.

Pursuant to and subject to the terms and conditions of the Investment Agreement, as long as Synchron's fully diluted ownership in the Company is at least 33.0%, Synchron has the right to designate two directors for appointment or election to the Board, where the Board is comprised of six or seven directors following such appointment or election. Messrs. Roberts and Mushinski were identified by Synchron as its two designees and has served on the Board beginning on November 17, 2017. On October 16, 2019, the Company issued to Synchron an additional 24,175,000 Common Shares in connection with the exercise by Synchron of the Option. As a result, Synchron's ownership of outstanding Common Shares increased from approximately 33.5% to approximately 49.0%. With Synchron's exercise of the Option, Synchron obtained the right to designate one additional director for appointment or election to the Board.

During the two most recent fiscal years ended December 31, 2024 and 2023, the Company did not consult with Haynie regarding (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company's financial statements by Haynie, in either case where written or oral advice provided by Haynie would be an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any other matter that was either the subject of a disagreement between the Company and its former auditor (as defined in Item 304(a)(1)(iv) of Regulation S-K) or a reportable event with the Company's former independent registered public accounting firm (as described in Item 304(a)(1)(v) of Regulation S-K).

A resolution will be presented at the Meeting to appoint Haynie to serve as the independent registered public accounting firm of the Company until the next annual meeting of shareholders of the Company at an amount of remuneration to be fixed by the directors.

Executed Proxies received will, on any poll, be voted as directed, or, if there is no direction, will be voted "FOR" the appointment of Haynie as the independent registered public accounting firm of the Company until the next annual meeting of shareholders of the Company at an amount of remuneration to be fixed by the directors.

**Communications with the Board of Directors**

Shareholders may send communications to the Board, the Chairman or one or more of the non-management directors by using the contact information provided on the Company's website at *www.rareelementresources.com*. Shareholders may also send communications by letter addressed to the Corporate Secretary of the Company at P.O. Box 271049, Littleton, Colorado 80127.

The receipt of concerns about the Company's accounting, internal controls, auditing matters or business practices will be reported to the Audit Committee. The receipt of other concerns will be reported to the appropriate Committee(s) of the Board and/or to the Board itself, when necessary.

**Board Leadership Structure**

Currently, the Company has a separate President and CEO, Kenneth Mushinski, and Chairman of the Board, Gerald W. Grandey. Mr. Grandey is an independent director. Mr. Grandey was appointed as the Chairman of the Board of the Company on June 10, 2015, and Mr. Mushinski was appointed as the President and CEO of the Company effective as of May 1, 2024.

The Board has reviewed the Company's current Board leadership structure in light of the composition of the Board, the Company's size, the nature of the Company's business, the regulatory framework under which the Company operates, the Company's share base, the Company's peer group and other relevant factors, and has determined that a separate Chairman of the Board and CEO is currently the most appropriate leadership structure for the Company.

The Audit Committee is comprised of two independent directors and one non-independent director, pursuant to Section 6.1.1(6) of Canada's National Instrument 52-110 – *Audit Committees* ("NI 52-110"). The NCG&C Committee is comprised of one independent director and three non-independent directors, as described in more detail below. Both committees meet regularly without management present.

The Board believes that adequate structures and processes are in place to facilitate the functioning of the Board independently of the Company's management. Meetings of the independent directors, when held, are chaired by the independent Chairman, give independent directors the opportunity for open and frank discussions on all matters they consider relevant, including an assessment of their own performance.

**Ethical Business Conduct**

The Board has adopted a Code of Conduct, which is based on the fundamental principles of honesty, loyalty, fairness, forthrightness, and use of common sense in general. The Code of Conduct is available on the Company's website at *www.rareelementresources.com* and on the Canadian System for Electronic Document Analysis and Retrieval ("SEDAR+") at *www.sedarplus.ca*. The Code of Conduct applies to all directors, officers and employees, including the principal executive, financial and accounting officers. The Audit Committee is responsible for setting the standards of business conduct contained in the Code of Conduct, and it annually reviews the Code of Conduct.

The Board, through the NCG&C Committee, is responsible for monitoring compliance with the Code of Conduct. The NCG&C Committee reviews, with management, any issues with respect to compliance with the Code of Conduct. The Board discloses on the Company's website any waiver from a provision of its Code of Conduct that applies to any of its principal executive officer, principal financial officer, principal accounting officer or controller or persons performing similar functions that relates to any element of its Code of Conduct. No waivers were granted from the requirements of the Company's Code of Conduct during the fiscal year ended December 31, 2024, or during the subsequent period through to the date of this Circular.

The Board ensures that the directors exercise independent judgment in considering transactions and agreements in respect of which a director or executive officer has a material interest. The Code of Conduct sets out the procedure with respect to reporting conflicts of interest. Actual or potential conflicts of interests are reported to the Chair of the NCG&C Committee. Members of the NCG&C Committee are required to be particularly vigilant in reviewing and approving conflicts of interests.

**Board Role in Risk Oversight**

The understanding, identification and management of risk are essential elements for the successful management of the Company.

Risk oversight begins with the Board and the Audit Committee. The Audit Committee is currently chaired by Barton S. Brundage. Two members of the Audit Committee are considered to be independent under Exchange Act rules. See section entitled "Audit Committee Report" for further description of Audit Committee independence determinations.

The Audit Committee reviews and discusses policies with respect to risk assessment and risk management. The Audit Committee also has oversight responsibility with respect to the integrity of the Company's financial reporting process and systems of internal control regarding finance and accounting, as well as its financial statements. The Audit Committee receives feedback from the external auditor with respect to certain financial accounting and internal control risks.

Management and third-party consultants perform ongoing internal control testing and assessments. Management also provides reliable and timely information to the Board regarding the Company's effectiveness in identifying and appropriately controlling risks. Annually, management presents to the Audit Committee a report summarizing the review of the Company's methods for identifying and managing risks. At least quarterly, management and the Audit Committee review the Company's risk management program with the Board.

The Company also has a comprehensive internal risk framework, which facilitates performance of risk oversight by the Board and the Audit Committee. The Company's risk management framework is designed to:

● provide that risks are identified, monitored, reported and quantified properly;

● define and communicate the types and amount of risk that the Company is willing to take;

● communicate to the appropriate management level the type and amount of risk taken;

● maintain a risk management program that is independent of the risk-taking activities; and

● promote a strong risk management culture that encourages a focus on risk-adjusted performance.

**NOMINATING, CORPORATE GOVERNANCE**

**AND COMPENSATION COMMITTEE**

The current members of the NCG&C Committee are Nicole J. Champine (Chair), Craig S. Bartels, Paul J. Hickey, and Pamela L. Saxton. Three of the current members of the NCG&C Committee are not considered to be independent directors within the meaning of NI 58-101. The Board determined that Ms. Champine and Mr. Bartels are not independent based upon their employment with an affiliate of Synchron, the Company's majority shareholder. The Board determined that Mr. Hickey is not independent based upon his position as, among other things, a consultant to a subsidiary of the Company. The NCG&C Committee met five times during the fiscal year ended December 31, 2024.

**NCG&C Committee Charter**

The NCG&C Committee is governed by a charter which sets forth the NCG&C Committee functions, which are, among other things, to establish procedures for the director nomination process and recommend nominees for election to the Board; to develop and periodically review the effectiveness of the Board's corporate governance guidelines; and to determine and recommend to the independent members of the Board the base salaries and annual incentive awards, including cash and any equity-based incentive awards for the CEO, and where applicable, in consultation with the CEO, for other senior officers, on an annual basis. The NCG&C Committee Charter is available on the Company's website at *www.rareelementresources.com*.

**Board Nominating Procedures**

The NCG&C Committee believes that candidates for the Board should have (i) the ability to exercise objectivity and independence in making informed business decisions; (ii) extensive knowledge, experience and judgment; (iii) integrity; (iv) loyalty to the interests of the Company and its shareholders; (v) a willingness to devote the extensive time necessary to fulfill a director's duties; (vi) the ability to contribute to the diversity of perspectives present in board deliberations; and (vii) an appreciation of the role of the Company in society. The NCG&C Committee considers candidates meeting these criteria who are suggested by directors, management, shareholders and search firms hired to identify and evaluate qualified candidates. Please see the section captioned "Proposal No. 1: Election of Directors—Director and Director Nominee Experience and Qualifications" for further information on board qualification criteria.

Shareholders may submit recommendations in writing by a letter addressed to the CEO of the Company or the Chair of the NCG&C Committee. The NCG&C Committee will carefully consider each shareholder recommendation, evaluating each shareholder-recommended candidate for director under the same standards as candidates identified by any other method.

**Gender Diversity on the Board**

The NCG&C Committee and the Board do not currently have a formal policy with regard to the consideration of gender diversity in identifying director nominees. While the Board recognizes the benefits of diversity and inclusion at all levels within its organization, it does not currently have any targets, rules or formal policies that specifically require the identification, consideration, nomination or appointment of female board nominees or candidates for executive management positions or that would otherwise force the composition of the Board or the Company's executive management team. Board nominations and appointments are assessed solely based upon the merits of the candidates, in the context of the skills, experience and independence which the Board requires in order to be effective; however, the NCG&C Committee encourages candidate diversity, including gender diversity, in the process of identifying and vetting all candidates. When searching for candidates for senior management positions, the Board focuses on attracting and retaining experienced and highly skilled individuals who can add value to its business, while also encouraging diversity.

Currently, the Company has two female Board members, and one female executive officer. The NCG&C Committee may consider the introduction of a formal policy regarding diversity and inclusion in the future.

**Term Limits and Board Composition**

The NCG&C Committee and the Board do not currently have a formal policy with regard to director term limits or retirement age in connection with individuals nominated for election as it does not believe that such policies would be in the best interests of the Company. The Company operates in a unique industry, making it difficult to find qualified directors with the appropriate background and experience, and the introduction of a director term limit or retirement policy would impose further difficulty. Notwithstanding the foregoing, the NCG&C Committee annually reviews and makes recommendations regarding the size, composition, operation, practice and tenure policies of the Board, with a view to effective oversight and decision making. The NCG&C Committee believes that when selecting candidates to serve on the Board, it is in the best interests of the Company to consider the diversity of experience of the Board and review candidates who possess a range of skills, expertise, personality, education, background and other qualities for nomination. The Board strives to achieve a balance between the desirability to have a depth of experiences from its members and the need for renewal and new perspectives. The NCG&C Committee assesses the effectiveness of this approach as part of its annual review of its charter.

The NCG&C Committee reviews the size of the Board annually. The Board must have enough directors to carry out its duties efficiently, while presenting a diversity of views and experience. The Board believes that its current size of seven members best serves the Company's needs in the fiscal year to come. The NCG&C Committee recommended to the Board all nominees for directors in this Circular.

Pursuant to and subject to the terms and conditions of the Investment Agreement, Synchron has the right to designate three directors for appointment or election to the Board, where the Board is comprised of seven directors following such appointment or election.

**Compensation Functions**

The NCG&C Committee is responsible for reviewing and making recommendations to the Board regarding the Company's compensation policies and programs as well as salary and benefit levels for individual executive officers. The Board, in turn, gives final approval on compensation matters. The NCG&C Committee does not and cannot delegate its authority to determine and recommend director and executive officer compensation.

**AUDIT COMMITTEE REPORT**

The Company has a separately designated, standing Audit Committee established in accordance with Section 3(a)(58)(A) of the Exchange Act. Under Canadian securities laws, the Company is required to have an audit committee comprised of not less than three directors. Two of three members of the Audit Committee must meet the independence requirements imposed by applicable Canadian securities law and therefore must not be an executive officers, employees or control persons of the Company or an affiliate of the Company. The Company's current Audit Committee consists of Barton S. Brundage (Chair), Gerald W. Grandey and Pamela L. Saxton. See "Proposal No. 1—Election of Directors—Director and Director Nominee Experience and Qualifications" for biographical information and the experience of Messrs. Brundage and Grandey, and Ms. Saxton. The Audit Committee's functions are to oversee the accounting and financial reporting process and the audit of the annual financial statements of the Company. The Audit Committee met five times during the fiscal year ended December 31, 2024.

**Audit Committee Charter**

The Audit Committee, under the guidance of the Audit Committee Charter approved by the Board, assists the Board in fulfilling its oversight responsibilities by reviewing (i) the financial statements, reports and other information provided to shareholders, regulators and others; (ii) the independent auditor's qualifications, independence and performance; (iii) the internal controls that management and the Board have established; (iv) the audit, accounting and financial reporting processes generally; (v) risk management program completeness and effectiveness; and (vi) compliance by the Company with legal and regulatory requirements. The text of the Audit Committee's Charter is appended to this Circular as Appendix "A" and is also available on the Company's website at *www.rareelementresources.com*.

**Independence**

The Board has determined that two of the members of the Audit Committee are independent within the meaning of NI 52-110. The Board determined that Mr. Grandey and Ms. Saxton are independent but that Mr. Brundage is not independent based upon his employment with an affiliate of Synchron, the Company's majority shareholder. As a result, the Audit Committee is comprised of a majority of independent directors.

**Audit Committee Financial Expert**

The Board has determined that Barton S. Brundage, Chair of the Audit Committee, satisfies the requirement of an "audit committee financial expert," as defined under Item 407 of Regulation S-K, and each of Messrs. Brundage and Grandey and Ms. Saxton is "financially literate" within the meaning thereof set forth in NI 52-110.

**Audit Committee Oversight**

Since the commencement of the fiscal year ended December 31, 2024, the Audit Committee has not made any recommendations to nominate or compensate an external auditor which were not adopted by the Board.

**Audit Committee Report**

The Audit Committee has reviewed and discussed with the Company's management the Company's audited consolidated balance sheet at December 31, 2024 and consolidated statements of operations and comprehensive loss, cash flows and shareholder's equity for the fiscal year ended December 31, 2024.

The Audit Committee has discussed with Haynie & Company ("Haynie") the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board ("PCAOB") and the SEC.

The Audit Committee has received the written disclosures and the letter from Haynie required by the applicable requirements of the PCAOB regarding Haynie's communications with the Audit Committee concerning independence and has discussed with Haynie its independence.

Based on the financial statement review, discussions with Haynie and such other matters deemed relevant and appropriate by the Audit Committee, the Audit Committee recommended to the Board that the Company's financial statements for the fiscal year ended December 31, 2024 and the related management's discussion and analysis be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

Consistent with applicable laws, other than audit, review or attestation services, all other services provided by the Company's auditor are to be pre-approved by one or more members of the Audit Committee pursuant to authority delegated by the Audit Committee, provided that the Audit Committee is informed of each particular service. All of the engagements and fees discussed below under the heading "Audit, Audit-Related, Tax, and Other Fees" for the fiscal years ended December 31, 2024 and 2023 were pre-approved by the Audit Committee.

**PAY VERSUS PERFORMANCE DISCLOSURE**

The following pay versus performance disclosure is required by rules adopted by the SEC in the fall of 2022. The disclosure required for smaller reporting companies consists of a Pay Versus Performance ("PvP") Table and reconciliation of the information reported in the table. The SEC believes this disclosure will help shareholders better evaluate the link between executive pay and performance, both for the Company on a stand-alone basis and as compared to other publicly traded companies.

The PvP Table is highly regulated and requires pay disclosures that are significantly different than what we have customarily provided in the Summary Compensation Table ("SCT") and the other executive compensation tables in prior years. The table currently provides SEC mandated compensation data for fiscal years 2022, 2023 and 2024 for our NEOs, along with certain financial performance measures. In reviewing the table, our shareholders should note the following:

● The amounts in columns (b) and (d) of the table are taken from or derived directly from the total compensation paid to the relevant NEOs as reported in this year's or prior years' SCT;

● The Compensation Actually Paid ("CAP") totals in columns (c) and (e) represent a new type of compensation disclosure mandated by the SEC, the intent of which is to try and isolate the amount of compensation earned by the relevant NEO(s) in each year. To calculate CAP, we are required to start with the totals for that year as reported in the SCT, deduct the SCT values for stock and option awards, and then add back amounts for new and previously outstanding stock and option awards in a manner mandated by the SEC. The disclosure and calculations are complex and can be confusing, and the amounts determined in accordance with the rules often bear no relation to the money or the economic value received or monetized by a particular NEO in the given year. We therefore caution that the term CAP should not be read literally and does not actually reflect the "take home" amounts received by our NEOs in a given year; and

● The SEC rules require that we include in the PvP Table information regarding our U.S. GAAP net loss results (as reported in column (g)). U.S. GAAP net loss was not a performance metric in any of our compensation programs and did not affect the compensation awarded to our NEOs for the years covered by the PvP Table. We are nonetheless required to include such information in the table, and we urge our investors to keep in mind that U.S. GAAP net loss was not a factor in the determination of the amounts of pay awarded to or realized by our NEOs and the NCG&C Committee did not consider the pay versus performance measure when making its incentive compensation decisions.

The following table sets forth information concerning the compensation of our principal executive officers, or "PEOs," and the compensation of our other non-PEO NEO, for each of the years ended December 31, 2024, 2023 and 2022, as such compensation relates to our financial performance for each year.

**Analysis of the Information Presented in the Pay Versus Performance Table**

Because we are a pre-production stage mining company, we did not generate any revenues from continuing operations during the periods presented. Consequently, we have not historically focused on net income (loss) as a performance measure for our executive compensation programs and as noted above, the NCG&C Committee does not consider the pay versus performance measure when making its incentive compensation decision.

The following charts illustrate, across the years covered in the PvP Table, the relationships between CAP to our PEOs and non-PEO NEOs and total shareholder return and net loss, as applicable, over those same periods.

**INDEBTEDNESS OF DIRECTORS AND EXECUTIVE OFFICERS**

None of the current or former directors, executive officers of the Company or the proposed nominees for election to the Board, nor any associate or affiliate of the foregoing persons, are or have been indebted to the Company since the beginning of the fiscal year ended December 31, 2024.

**SECURITIES AUTHORIZED FOR ISSUANCE UNDER EQUITY COMPENSATION PLANS**

For information with respect to securities of the Company authorized for issuance under the Company's equity compensation plans please see "Part II—Equity Compensation Plan Information" in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2024, which is available under the Company's profile at *www.sedarplus.ca* and on EDGAR at *www.sec.gov/edgar.shtml* and which is also available free of charge upon request to the Company.

**Policies and Practices for Granting Stock Options and Stock Appreciation Rights**

While we do not have a formal written policy in place with regard to the timing of stock option and stock appreciation rights awards in relation to the disclosure of material nonpublic information, the NCG&C Committee does not seek to time equity grants to take advantage of information, either positive or negative, about the Company that has not been publicly disclosed. Previous awards of stock options have generally been made in tandem with and at the same time that the Company has issued other types of equity awards as part of its ordinary annual grant practices. Stock option grants, if made, are effective on the date the award determination is made by the NCG&C Committee, and the exercise price of stock options is the closing market price of the Common Shares on the last trading day immediately preceding the date of grant.

**INTERESTS OF CERTAIN PERSONS IN MATTERS TO BE ACTED UPON**

No director or executive officer of the Company or any of the Board's nominees for election as a director of the Company, nor any associate or affiliate of the foregoing persons, has any material interest, direct or indirect, by way of beneficial ownership of securities or otherwise, since the beginning of the Company's last fiscal year in matters to be acted upon at the Meeting, other than the election of directors.

**INTERESTS OF INFORMED PERSONS IN MATERIAL TRANSACTIONS**

**Cost Share Agreement with General Atomics**

On November 30, 2021, the Company and General Atomics, a California corporation and an affiliate of Synchron ("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 certain costs incurred by General Atomics and the consortium for the design, construction, and operation of the Demonstration Plant near the Bear Lodge REE Project in Upton, Wyoming.

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, up to $2,500,000, 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.

As of July 1, 2025, an amendment to the Cost Share Agreement was in the process of being finalized with General Atomics, with completion expected in the second half of 2025.

**Professional Services Agreement with** **Ms. Kast**

Prior to her employment in July 2024, Ms. Kast had been since June 2015, a consultant of Rare Element Resources, Inc., a subsidiary of the Company, and had served as a Board member since August 2022. From July 2012 to May 2015, Ms. Kast served as the Vice President, General Counsel, Chief Administrative Officer, and Corporate Secretary of the Company. On February 17, 2021, Rare Element Resources, Inc. entered into an updated professional services agreement, effective as of March 1, 2021, with Ms. Kast (the "Professional Services Agreement") that was subsequently extended on an annual basis and which was terminated on June 30, 2024, with Ms. Kast's employment. Pursuant to the Professional Services Agreement, Ms. Kast performed business consulting and administrative oversight services for Rare Element Resources, Inc., and the Company. The Professional Services Agreement provided that Ms. Kast be paid a monthly retainer and be eligible for an annual performance bonus at the discretion of the Board. For the fiscal years 2024 (through her employment date) and 2023, Ms. Kast was paid monthly retainers of $21,250 and $20,208, respectively, and received cash bonuses of $20,000 and $82,500, respectively. Ms. Kast received a second cash bonus of $80,000 in 2024 following her hiring as a Company employee.

Ms. Kast is also eligible for stock option grants pursuant to the Company's equity incentive plan and as approved by the Board. On January 4, 2023, Ms. Kast received a stock option grant of 225,000 that vested 50% on each of July 4, 2023, and January 4, 2024.

**Legal and Consulting Arrangements with Mr. Hickey**

In June 2022, Mr. Hickey was retained as a consultant to Rare Element Resources, Inc., a subsidiary of the Company, and was paid a monthly retainer of $5,000 during fiscal years 2023 and 2022 for business and community relations services. Mr. Hickey serves as an advisor to affiliates of Synchron, the Company's majority shareholder, in several capacities, including as registered agent in the state of Wyoming. Mr. Hickey's monthly retainer with Rare Element Resources, Inc. was adjusted to $6,000 in 2024 and remains the same for 2025. Prior to his retirement as a partner of Hickey & Evans, LLP, he served as counsel to General Atomics (an affiliate of Synchron) and certain of its affiliates for various matters from 1980 through 2022.

Mr. Hickey is also eligible for stock option grants pursuant to the Company's equity incentive plan and as approved by the Board. On January 4, 2023, Mr. Hickey received a stock option grant of 50,000 that vested 50% on each of July 4, 2023, and January 4, 2024.

**MANAGEMENT CONTRACTS**

No management functions of the Company are, to any substantial degree, performed by a person or company other than the directors or executive officers of the Company, in their roles as such.

**REVIEW, APPROVAL OR RATIFICATION OF TRANSACTIONS WITH RELATED PARTIES**

The Company's written corporate governance policies generally discourage transactions involving a potential conflict of interest. The NCG&C Committee is generally responsible for overseeing compliance with the Company's corporate governance policies, which require that transactions that could reasonably be considered to present a conflict of interest be reported to the NCG&C Committee. However, the Audit Committee is responsible for overseeing compliance with the Code of Conduct contained in the Company's corporate governance policies. Specifically, the Audit Committee is responsible for reviewing and overseeing any transaction or contract exceeding or likely to exceed $120,000 involving the Company and a related party, including transactions subject to disclosure under Item 404 of Regulation S-K. Generally, in reviewing such transactions, the Audit Committee considers the relevant facts and circumstances available and deemed relevant to each determination.

Except for the Cost Share Agreement with General Atomics, the prior Professional Services Agreement with Ms. Kast and the legal and consulting arrangements with Mr. Hickey referenced above, there are no material interests, direct or indirect, of any of the current directors, executive officers, or any shareholder that beneficially owns, directly or indirectly, more than 5% of the outstanding Common Shares, or immediate family members of such persons, in any transaction since January 1, 2023 or in any proposed transaction in which the amount involved exceeded $120,000.

**GENERAL MATTERS**

It is not known whether any other matters will come before the Meeting other than those set forth above and in the Notice of Meeting, but if any other matters do arise, the person named in the Proxy intends to vote on any poll, in accordance with his or her best judgment, exercising discretionary authority with respect to amendments or variations of matters set forth in the Notice of Meeting and other matters which may properly come before the Meeting or any adjournment of the Meeting.

**SHAREHOLDER PROPOSALS**

Under the BCA, the statute under which the Company is incorporated, shareholder proposals, including director nominees, must be received at the registered office of the Company at least three months before the anniversary of the previous year's annual general meeting. Under Rule 14a-8(e) of Regulation 14A to the Exchange Act, subject to certain exceptions, shareholder proposals must be received at the Company's principal executive offices not less than 120 calendar days before the one-year anniversary of the Company's release to shareholders of its management information and proxy circular in connection with the previous year's annual meeting of shareholders. Because the shareholder proposal deadline under the BCA is more stringent for the Company and more favourable for shareholders, the Company will abide by it. Accordingly, to be eligible for inclusion in the Company's management information and proxy circular for the 2026 annual meeting of shareholders of the Company, shareholder proposals prepared in accordance with applicable laws must be received at the Company's registered office on or before June 9, 2026.

**Advance Notice Policy**

The Board adopted an advance notice policy (the "Advance Notice Policy") on November 7, 2012. The purpose of the Advance Notice Policy is to (i) facilitate an orderly and efficient annual general or, where the need arises, special meeting process, (ii) ensure that all shareholders receive adequate notice of the director nominations and sufficient information regarding all director nominees, and (iii) allow shareholders to register an informed vote after having been afforded reasonable time for appropriate deliberation.

The Advance Notice Policy, among other things, includes a provision that requires advance notice to the Company in certain circumstances where nominations of persons for election to the Board are made by shareholders of the Company. The Advance Notice Policy fixes a deadline by which director nominations must be submitted to the Company prior to any annual or special meeting of shareholders and sets forth the information that must be included in the notice to the Company for the notice to be in proper written form.

In the case of an annual meeting of shareholders, notice to the Company must be made not less than 30 days nor more than 65 days prior to the date of the annual meeting; provided, however, that in the event that the annual meeting is to be held on a date that is less than 50 days after the date on which the first public announcement of the date of the annual meeting was made, notice may be made not later than the close of business on the 10th day following such public announcement.

In the case of a special meeting of shareholders, which is not also an annual meeting, called for the purpose of electing directors (whether or not called for other purposes), notice to the Company must be made not later than the close of business on the 15th day following the day on which the first public announcement of the date of the special meeting was made. The full text of the Advance Notice Policy is available under the Company's profile at *www.sedarplus.ca*.

**DELINQUENT SECTION 16(a) REPORTS**

Section 16(a) of the Exchange Act requires the Company's officers and directors and persons who own more than 10% of a registered class of our equity securities to file initial reports of ownership of our equity securities on Form 3 and reports of changes in ownership on Form 4 or Form 5, as appropriate. Persons subject to Section 16 are required by SEC regulations to furnish us with copies of all Section 16(a) forms that they file. Based solely on a review of such forms furnished to the Company, we believe that for the fiscal year ended December 31, 2024, all required reports were filed on a timely basis under Section 16(a).

**MULTIPLE SHAREHOLDERS SHARING THE SAME ADDRESS**

U.S. regulations regarding the delivery of copies of proxy materials and annual reports to shareholders permit the Company and brokerage firms to send one annual report and proxy statement to multiple shareholders who share the same address under certain circumstances. Shareholders who hold their Common Shares through a broker may have consented to reducing the number of copies of materials delivered to their address. In the event that a shareholder wishes to revoke such a consent previously provided to a broker, the shareholder must contact the broker to revoke the consent. In any event, if a shareholder wishes to receive a separate Circular and accompanying materials for the Meeting or the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2024, the shareholder may receive copies by contacting the Corporate Secretary of the Company at P.O. Box 271049, Littleton, Colorado 80127. Shareholders receiving multiple copies of these documents at the same address can request delivery of a single copy of these documents by contacting the Company in the same manner. Persons holding Common Shares through a broker can request a single copy by contacting the broker.

**BOARD APPROVAL**

The contents of this Circular have been approved and its mailing authorized by the Board.

DATED at Littleton, Colorado, the 28th day of July, 2025.
