Completion of the Arrangement is subject to the satisfaction or waiver of certain conditions. No New GMIN Shares or Spinco Shares will be issued to Reunion Gold Shareholders prior to the effective time of the Arrangement, as set forth in the Plan of Arrangement (the "Effective Time").

This Letter of Transmittal is for use by Registered Shareholders only and is not to be used by beneficial Reunion Gold Shareholders ("Non-Registered Shareholders"). A Non-Registered Shareholder does not have Reunion Gold Shares registered in such Reunion Gold Shareholder's own name; rather, such Reunion Gold Shares are registered in the name of the broker, investment dealer, bank, trust company, depositary, nominee or other intermediary (each, an "Intermediary") through which such Reunion Gold Shareholder purchased Reunion Gold Shares or in the name of a clearing agency (such as CDS Clearing and Depository Services Inc.) of which the Intermediary is a participant. If you are a Non-Registered Shareholder, you should contact your Intermediary for instructions and assistance in receiving the New GMIN Shares and Spinco Shares for your Reunion Gold Shares, and providing instructions regarding the election described herein.

No certificates representing fractional New GMIN Shares or fractional Spinco Shares shall be issued upon the surrender for exchange of certificate(s) or Direct Registration System Advice Notice(s) or Statement(s) ("DRS Advice(s)") representing Reunion Gold Shares by Reunion Gold Shareholders pursuant to the Arrangement and no dividend, stock split or other change in the capital structure of New GMIN or Spinco shall relate to any such fractional security and such fractional interests shall not entitle the owner thereof to exercise any rights as a holder of New GMIN Shares or Spinco Shares, as applicable. No fractional New GMIN Shares or fractional Spinco Shares shall be issued to Reunion Gold Shareholders and the number of New GMIN Shares and the number of Spinco Shares to be issued to Reunion Gold Shareholders will be rounded down to the nearest whole New GMIN Share and the nearest whole Spinco Share, respectively, in the event that a Reunion Gold Shareholder is entitled to a fractional share, without any additional compensation in lieu of such fractional share.

In order to receive the New GMIN Shares and Spinco Shares, if any, that a Reunion Gold Shareholder is entitled to receive pursuant to the Arrangement, Registered Shareholders are required to deposit the certificate(s) or DRS Advice(s), representing their Reunion Gold Shares with the Depositary. This Letter of Transmittal properly completed and duly executed, together with all other required documents, must accompany the certificate(s) or DRS Advice(s) for Reunion Gold Shares deposited for receipt of New GMIN Shares and Spinco Shares pursuant to the Arrangement.

Whether or not the Registered Shareholder delivers the required documentation to the Depositary, as of the Effective Time, the Registered Shareholder will cease to be a holder of Reunion Gold Shares and, subject to the ultimate expiry deadline identified below, will only be entitled to receive the New GMIN Shares and Spinco Shares, if any, to which the Registered Shareholder is entitled under the Arrangement. REGISTERED SHAREHOLDERS WHO DO NOT DELIVER THE CERTIFICATE(S) OR DRS ADVICE(S), AS APPLICABLE, REPRESENTING THEIR REUNION GOLD SHARES AND ALL OTHER REQUIRED DOCUMENTS TO THE DEPOSITARY ON OR BEFORE THE SIXTH ANNIVERSARY OF THE EFFECTIVE DATE WILL LOSE THEIR RIGHT TO RECEIVE ANY NEW GMIN SHARES AND SPINCO SHARES FOR THEIR REUNION GOLD SHARES AND ANY CLAIM OR INTEREST OF ANY KIND OR NATURE AGAINST REUNION GOLD, GMIN, SPINCO, NEW GMIN OR THE DEPOSITARY.

Delivery of this Letter of Transmittal to an address other than as set forth on the last page of this Letter of Transmittal will not constitute a valid delivery.

The undersigned hereby acknowledges that the delivery of the Deposited Reunion Gold Shares shall be effected and the risk of loss to such Deposited Reunion Gold Shares shall pass only upon proper receipt thereof by the Depositary.

The undersigned acknowledges that all authority conferred, or agreed to be conferred, by the undersigned herein may be exercised during any subsequent legal incapacity of the undersigned and shall survive the death, incapacity, bankruptcy or insolvency of the undersigned and all obligations of the undersigned herein shall be binding upon the heirs, personal or legal representatives, successors and assigns of the undersigned.

The undersigned acknowledges that if the Arrangement is completed, the delivery of Deposited Reunion Gold Shares pursuant to this Letter of Transmittal is irrevocable. If the Arrangement is not completed or proceeded with, the enclosed certificate(s) or DRS Advice(s), as applicable, and all other ancillary documents will be returned as soon as possible to the undersigned at the address set out below on the signature page of this Letter of Transmittal or in Box B, as applicable, or, failing such address being specified, to the undersigned at the last address of the undersigned as it appears on the securities register of Reunion Gold.

It is understood that the undersigned will not receive the New GMIN Shares or the Spinco Shares under the Arrangement in respect of the Deposited Reunion Gold Shares until following the Effective Time and after certificate(s) or DRS Advice(s) representing the Deposited Reunion Gold Shares owned by the undersigned are received by the Depositary at the address set forth on the back of this Letter of Transmittal, together with a duly completed Letter of Transmittal and such additional documents as the Depositary may require, and until the same are processed by the Depositary. It is understood that under no circumstances will interest accrue or be paid in respect of the Deposited Reunion Gold Shares in connection with the Arrangement.

The undersigned acknowledges that New GMIN, GMIN, Reunion Gold, Spinco and the Depositary shall be entitled to deduct and withhold from any consideration otherwise payable to any former Reunion Gold Shareholder under the Arrangement and from other distributions otherwise payable to any former Reunion Gold Shareholder such amounts as Reunion Gold, GMIN, New GMIN, Spinco or the Depositary is required or permitted to deduct and withhold with respect to such payment under the Tax Act or any provision of any applicable federal, provincial, state, local or foreign tax law or treaty (including the United States Internal Revenue Code of 1986, as amended, and the rules and regulations promulgated thereunder), in each case, as amended. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to the former Reunion Gold Shareholder in respect of which

- 4 -

such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority. The undersigned acknowledges that it has consulted or has had the opportunity to consult its own tax advisor with respect to the potential income tax consequences to it of the Arrangement, including any elections to be made in respect thereof.

The undersigned understands and acknowledges that the New GMIN Shares and the Spinco Shares to be received by the undersigned pursuant to the Arrangement have not been registered under the United States Securities Act of 1933, as amended (the "U.S. Securities Act"), and are being issued in reliance on the exemption from the registration requirements of the U.S. Securities Act provided by Section 3(a)(10) thereof and similar exemptions from registration under applicable U.S. state securities laws. The restrictions on resale of the New GMIN Shares and the Spinco Shares outstanding following the Effective Date will depend on whether such former Reunion Gold Shareholder is an "affiliate" of New GMIN or Spinco, as applicable, after the Effective Date or had been such an "affiliate" at any time within 90 days immediately preceding the Effective Date. As defined in Rule 144 under the U.S. Securities Act, an "affiliate" of an issuer is a person that directly, or indirectly through one or more intermediaries, controls, is controlled by, or is under common control with, that issuer. Typically, persons who are executive officers, directors or 10% (or greater) shareholders of an issuer are considered to be its "affiliates", as well as any other person or group that actually controls the issuer. Persons who are affiliates of New GMIN or Spinco, as applicable, after the Effective Date, or within 90 days immediately preceding the Effective Date, may not sell their New GMIN Shares and Spinco Shares, as applicable, that they receive in connection with the Arrangement without registration under the U.S. Securities Act, unless an exemption or exclusion from such registration is available, such as the exemption provided by Rule 144 under the U.S. Securities Act or the exclusion provided by Regulation S under the U.S. Securities Act, as more fully described in the Circular.

The foregoing discussion is only a general overview of certain requirements of U.S. federal securities laws applicable to the New GMIN Shares and Spinco Shares received upon completion of the Arrangement. All holders of such securities are urged to consult with counsel to ensure that any action taken with respect to their securities complies with applicable securities legislation, including any resale of such securities.

By reason of the use by the undersigned of an English language form of Letter of Transmittal, the undersigned shall be deemed to have required that any contract in connection with the delivery of the Reunion Gold Shares pursuant to the Arrangement through this Letter of Transmittal, as well as all documents related thereto, be drawn exclusively in the English language. En raison de l'utilisation d'une lettre d'envoi en langue anglaise par le

soussigné, le soussigné et les destinataires sont réputés avoir exigé que tout contrat relié à l'envoi d'actions ordinaires de Reunion Gold en vertu de l'arrangement au moyen de la présente lettre d'envoi, de même que tous les documents qui s'y rapportent, soient rédigés exclusivement en langue anglaise.

This letter will be governed by and construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein.

BOX E

OPT-OUT ELECTION

This Box E applies only to Non-Resident Reunion Gold Shareholders (as defined below) that meet specific eligibility criteria and that elects to make the Opt-Out Election. The Opt-Out Election is not available to Resident Reunion Gold Shareholders (as defined below). The Opt-Out Election made by a Registered Shareholder that does not meet the eligibility criteria described herein will not be valid and such Registered Shareholder will be treated in the manner the Registered Shareholder would have been treated if the Opt-Out Election had not been made. Any Non-Resident Reunion Gold Shareholder who has made a valid Opt-Out Election will be treated as an Electing Reunion Gold Shareholder (as defined below) under the Arrangement.

THE ELECTION DEADLINE IS NO LATER THAN 10:00 A.M. (EASTERN TIME) ON JULY 5, 2024, OR IF THE REUNION GOLD MEETING IS ADJOURNED OR POSTPONED, 48 HOURS (EXCLUDING WEEKENDS AND HOLIDAYS IN THE PROVINCES OF QUÉBEC AND ONTARIO) PRIOR TO THE TIME SET FOR THE ADJOURNED OR POSTPONED REUNION GOLD MEETING.

A summary of the principal Canadian federal income tax considerations in respect of the Arrangement including in respect of an Electing Reunion Gold Shareholder, is included in the Circular under "Certain Canadian Federal Income Tax Considerations - Holders Not Resident in Canada: Electing Reunion Gold Shareholders".

An "Electing Reunion Gold Shareholder" means any Non-Resident Reunion Gold Shareholder that has made an Opt- Out Election.

A "Non-ElectingReunion Gold Shareholders" means, (i) all Resident Reunion Gold Shareholders and (ii) any NonResident Reunion Gold Shareholders that have not, or are deemed not, to have made a valid Opt-Out Election.

A "Non-ResidentReunion Gold Shareholder" means a Reunion Gold Shareholder that, immediately prior to the Effective Time, is a non-resident of Canada for the purposes of the Tax Act, or a partnership any member of which is a non-resident of Canada for purposes of the Tax Act.

A "Resident Reunion Gold Shareholder" means a Reunion Gold Shareholder other than a Non-Resident Reunion Gold Shareholder.

As described in greater detail under "The Arrangement - Arrangement Steps" and "Matters Ancillary to the Arrangement - Reunion Gold Reorganization" of the Circular, Reunion Gold will undertake a capital and business reorganization as part of the Arrangement, which includes, among others, renaming and redesignating the current Reunion Gold Shares as "Reunion Gold Class A Shares" and creating a new class of shares consisting of an unlimited number of "Reunion Gold Class B Shares". In the course of the capital reorganization, each Reunion Gold Class A Share held by any Non-ElectingReunion Gold Shareholder before the reorganization shall be deemed to have been assigned and transferred to Reunion Gold for 1 Reunion Gold Class B Share and 0.05 of a Spinco Share. A Non-ResidentReunion Gold Shareholder may elect to make the Opt-OutElection and as a result, receive Spinco Shares on the reduction of stated capital of the Reunion Gold Class A Shares.

The Canadian federal income tax consequences may be materially different for Registered Shareholders that meet the eligibility criteria to be an Electing Reunion Gold Shareholder but does not make the Opt-Out Election, compared to Registered Shareholders that meet eligibility criteria to be an Electing Reunion Gold Shareholder and who makes the Opt-Out Election. Reunion Gold Shareholders should consult their own tax advisors for advice in respect of the consequences to them of the Arrangement having regard to their particular circumstances.

Non-Resident Reunion Gold Shareholders that wish to make the Opt-Out Election must place an "X" in the box below.

Certification instructions. You must cross out item 2 above if you have been notified by the IRS that you are currently subject to backup withholding because you have failed to report all interest and dividends on your tax return. For real estate transactions, item 2 does not apply. For mortgage interest paid, acquisition or abandonment of secured property, cancellation of debt, contributions to an individual retirement arrangement (IRA), and, generally, payments other than interest and dividends, you are not required to sign the certification, but you must provide your correct TIN. See the instructions for Part II, later.
