The Plan of Arrangement

At the Meeting, Securityholders will be asked to consider and, if deemed acceptable, pass a special resolution (the 鈥淎rrangement Resolution鈥�) approving an arrangement (the 鈥淎rrangement鈥�) with Torex Gold Resources Inc. (the 鈥淧urchaser鈥� or 鈥淭orex鈥�), pursuant to a statutory plan of arrangement (the 鈥淧lan of Arrangement鈥�) under Section 288 of the Business Corporations Act (British Columbia) whereby the Purchaser will, among other things, acquire all of the issued and outstanding Prime Shares. The Arrangement will be governed by and is subject to the terms of the arrangement agreement dated July 27, 2025 between the Company and the Purchaser (the 鈥淎rrangement Agreement鈥�).

The Consideration

Shareholders

Under the terms of the Arrangement Agreement, which was negotiated at arm鈥檚 length, and pursuant to the Plan of Arrangement, each Shareholder (other than those Shareholders validly exercising their dissent rights or the Purchaser or any of its affiliates) will receive 0.060 (the 鈥淓xchange Ratio鈥�) of a common share of Torex (each whole share, a 鈥淭orex Share鈥�) in exchange for each Prime Share held by such Shareholder immediately prior to the effective time of the Arrangement (the 鈥淓ffective Time鈥�), subject to adjustment in accordance with the Arrangement Agreement (the 鈥淐onsideration鈥�).

Option Holders

Pursuant to the Plan of Arrangement, each outstanding Prime Option, whether vested or unvested, will be deemed to be vested and will remain outstanding and will be exercisable until the earlier of the original expiry date of the Prime Option and the date that is twelve (12) months following the Effective Time. Upon completion of the Arrangement, the Prime Options will be exercisable for Torex Shares adjusted to reflect the Exchange Ratio.

RSU and DSU Holders

Pursuant to the Plan of Arrangement, each outstanding Prime RSU and Prime DSU of the Company, whether vested or unvested, will be deemed to be immediately and unconditionally vested and will be settled by Prime at the Effective Time in exchange for Prime Shares (less applicable withholdings). Such Prime Shares will be transferred to the Purchaser for the Consideration in accordance with the Plan of Arrangement, and each such Prime RSU and Prime DSU shall immediately be cancelled.

Warrant Holders

Upon completion of the Arrangement, each outstanding Prime Warrant will be exercisable for 0.060 of a Torex Share in lieu of each Prime Share that the holder thereof would otherwise have received on exercise of such Prime Warrant prior to the completion of the Arrangement (rounded down to the nearest whole number).

No Fractional Shares

No fractional Torex Shares will be issued in connection with the Arrangement. Any fractional Torex Shares to which a Securityholder may be entitled under the Arrangement will be rounded down to the nearest whole number of Torex Shares and no cash payment or other compensation in lieu of any fractional Torex Shares will be paid.

Reasons for the Plan of Arrangement and Board Recommendation

After careful consideration, including a thorough review of the Arrangement Agreement, the fairness opinion of BMO Capital Markets (鈥淏MO鈥�), and other matters, and taking into account the best interests of the Company, and after consultation with management and its financial and legal advisors, and upon the unanimous recommendation of the special committee of the board of directors of the Company (the 鈥淪pecial Committee鈥�), the board of directors of the Company (the 鈥淏oard鈥�) has unanimously determined the Arrangement is in the best interests of the Company and is fair to the Shareholders, has unanimously approved the Arrangement and the Arrangement Agreement and unanimously recommends that the Securityholders vote FOR the Arrangement Resolution.

In making its recommendations, the Board considered a number of factors as described in the Circular. The following are some of the principal reasons for the recommendation:

• Immediate and Significant Premium. The Consideration represents a premium of 32.4% to the 30-day volume weighted average price of the Prime Shares on the 海角社区官网Stock Exchange (鈥淭SX鈥�) as of July 25, 2025, the last trading day before the announcement of the Arrangement. Furthermore, the Consideration implies a premium of 18.5% to the closing price of the Prime Shares on the TSX as of July 25, 2025.
• Participation in an Established, High-Quality, Gold and Copper Producer with Substantial Growth Potential. The Arrangement provides Securityholders with (A) the opportunity to continue to participate in the future upside potential of the Company鈥檚 Los Reyes Project through their meaningful 10.7% equity ownership in Torex, (B) exposure to Torex鈥檚 free cash flowing Morelos Complex, comprising of the producing El Lim贸n Guajes and Media Luna mines along with the development stage EPO underground project, and (C) enhanced exploration upside through Torex鈥檚 Morelos Property, in addition to a suite of early-stage exploration projects acquired by Torex on August 20, 2025.
• De-Risking of Development of Los Reyes. The Arrangement provides an opportunity to leverage Torex鈥檚 Mexican expertise and strong technical capabilities for the development of the Los Reyes Project. Torex brings deep and recent expertise in discovering, permitting, building, and operating mines in Mexico, including the construction of the El Lim贸n Guajes and Media Luna mines, which were completed by Torex largely on schedule with minimal deviations from their original budgets. Torex has an experienced Mexican permitting and project/construction team ready and available to advance the Los Reyes Project.
• Enhanced Financial Strength. The Arrangement provides Securityholders access to Torex鈥檚 strong balance sheet, liquidity, and growing significant free cash flows from Media Luna. These strong financial resources are expected to support the advancement of the Los Reyes Project and eliminate financing and dilution risks to bring the project into production.
• Enhanced Capital Markets Profile. Torex has a market capitalization of approximately US$3.7 billion as of the date of the Circular, enabling Shareholders to benefit from increased market presence, analyst coverage, investor demand, and trading liquidity.
• Proven Leadership Team. Upon completion of the Arrangement, management of Torex will continue to feature proven and experienced mining and business leaders at both the board and executive team levels, with a proven track record of maximizing shareholder value.
• Business Climate and Review of Strategic Alternatives. After consultation on the proposed Arrangement with the Company鈥檚 financial and legal advisors, and after review of the current and prospective business climate in the precious metals industry and other strategic opportunities reasonably available to Prime, including continuation as an independent enterprise, and potential acquisitions and dispositions or other business combinations, in each case taking into account the potential benefits, risks and uncertainties associated with those other opportunities, the Special Committee and the Board believe that the Arrangement represents Prime鈥檚 best prospect for maximizing shareholder value.
• Fairness Opinion. The fairness opinion of BMO states that, as of the date of such opinion and based upon and subject to the various assumptions, limitations, qualifications and scope of review set forth therein, the Consideration to be received by the Shareholders (other than those Shareholders whose votes are required to be excluded from the vote pursuant to Section 8.1(2) of Multilateral Instrument 61-101 鈥� Protection of Minority Security Holders in Special Transactions (鈥淢I 61-101鈥�)) pursuant to the Arrangement, is fair, from a financial point of view, to such Shareholders.

Support Agreements

Each of the directors and officers of the Company and a significant shareholder of the Company, holding an aggregate of approximately 23% of the issued and outstanding Prime Shares and additionally, approximately 26% of the issued and outstanding Prime Securities, have entered into an agreement with the Purchaser pursuant to which they have agreed to, among other things, vote, or cause to be voted, all of the Prime Securities held or controlled by them (including any Prime Shares issuable upon exercise or settlement of Prime Options, Prime RSUs, Prime DSUs and Prime Warrants, as applicable) in favour of the Arrangement Resolution.

Subject to the satisfaction of customary closing conditions, including the parties obtaining the requisite regulatory approvals (including clearance under Mexican antitrust laws), the Arrangement is expected to close in H2 2025.

Securityholder Approval

In order to become effective, the Arrangement Resolution must be approved by at least (i) 66鈪�% of the votes cast on the Arrangement Resolution by Shareholders present in person or represented by proxy and entitled to vote at the Meeting, with each Prime Share entitling a Shareholder to one vote; (ii) 66鈪�% of the votes cast on the Arrangement Resolution by Securityholders present in person or represented by proxy and entitled to vote at the Meeting, voting together as a single class, with each Prime Security entitling a Securityholder to one vote; and (iii) a simple majority of votes attached to Prime Shares held by Shareholders present in person or represented by proxy and entitled to vote at the Meeting, excluding those votes attached to Prime Shares held or controlled by persons described in items (a) through (d) of Section 8.1(2) of MI 61-101.

Full details of the Arrangement are set out in the Circular. The Circular describes the Arrangement and includes certain additional information to assist you in considering how to vote on the Arrangement Resolution, including certain risk factors relating to the completion of the Arrangement.

The Arrangement is subject to customary closing conditions for a transaction of this nature, including, among other things, approval by the Securityholders, relevant stock exchange approvals, court approval and applicable government approvals by the relevant authorities. The Arrangement will not proceed if such approvals are not obtained.
