PROXY STATEMENT

The board of directors of Aura Minerals Inc. (the “Company” or “we”) is soliciting proxies for the annual general and special meeting of shareholders (the “AGM”) of the Company to be held virtually via live webcast at https://virtual-meetings.tsxtrust.com/en/1932/, on Tuesday, June 16, 2026, at 10:00 a.m. (ET).

This proxy statement and our annual report on Form 20-F for the fiscal year ended December 31, 2025 can be accessed, free of charge, on the Investor Relations section of the Company’s website https://www.auraminerals.com/en/investors/ com and on the Securities and Exchange Commission’s (the “SEC”) website at www.sec.gov.

On or about May 14, 2026, we first mailed to our shareholders our proxy materials, including our proxy statement, the notice to shareholders of our AGM and the proxy card, along with instructions on how to vote using the proxy card provided therewith. This proxy statement can also be accessed, free of charge, on the Investor Relations section of the Company’s website https://www.auraminerals.com/en/investors/ and on the SEC’s website at www.sec.gov.

Record Date, Share Ownership and Quorum

Only the holders of record of common shares (the “Common Shares”) of the Company as at the close of business on May 4, 2026 (the “Record Date”) are entitled to receive notice of and attend the AGM and any adjournment thereof. No person shall be entitled to vote at the AGM unless it is registered as a shareholder of the Company on the record date for the AGM.

As of the close of business on the Record Date, 83,789,223 Common Shares were issued and outstanding. At least two shareholders entitled to vote on resolutions to be considered at the AGM, present in person or by proxy or, if a corporation or other non-natural person, by their duly authorized representatives, constitute a quorum of the shareholders.

Voting and Solicitation

Each Common Share issued and outstanding as of the close of business on the Record Date is entitled to one vote at the AGM. The resolutions to be put to the vote at the AGM, other than the resolution in respect of Proposal 3, will be approved by an ordinary resolution (i.e. a simple majority of the votes cast, by or on behalf of, the shareholders attending and voting at the AGM). The resolution in respect of Proposal 3 to be put to the vote at the AGM will be approved by a special resolution (i.e. a two-thirds majority of the votes cast, by or on behalf of, the shareholders attending and voting at the AGM).

Internet Availability of Proxy Materials

We are furnishing proxy materials to our shareholders primarily via the Internet, instead of mailing printed copies of those materials to each shareholder.

On or about May 14, 2026, we first mailed to our shareholders a Notice of Notice and Access containing instructions on how to access our proxy materials. The Notice of Notice and Access of Proxy Materials directs shareholders to a website where they can access our proxy materials, including our proxy statement and our annual report, and view instructions on how to vote via the Internet, mobile device or by proxy card. This process is designed to expedite shareholders’ receipt of proxy materials, lower the cost of the AGM, and help conserve natural resources. If you received a Notice of Notice and Access of Proxy Materials and would prefer to receive a paper copy of our proxy materials, please follow the instructions included in the Notice of Notice and Access of Proxy Materials.

Voting by Holders of Common Shares

Common Shares that are properly voted via the Internet, mobile device or for which proxy cards are properly executed and returned within the deadline set forth below, will be voted at the AGM in accordance with the directions given. The proxy holder will also vote in the discretion of such proxy holder on any other matters that may properly come before the AGM, or at any adjournment thereof. Where any holder of Common Shares affirmatively abstains from voting on any particular resolution, the votes attaching to such Common Shares will not be included or counted in the determination of the number of Common Shares present and voting for the purposes of determining whether such resolution has been passed (but they will be counted for the purposes of determining the quorum, as described above).

Voting via the Internet or by mobile device helps save money by reducing postage and proxy tabulation costs. Each of these voting methods is available 24 hours per day, seven days per week. To vote by any of these methods, read this Proxy Statement, have your Notice of Notice and Access of Proxy Materials or proxy card in hand, and follow the instructions set forth in the Notice of Notice and Access of Proxy Materials or proxy card, as the case may be.

Proxies submitted by registered shareholders and street shareholders(whether by internet or by returning the proxy card) must be received by us no later than 10:00 a.m. (ET) on June 12, 2026, to ensureyour representation at our AGM, or no later than 48 hours (excluding Saturdays, Sundays and holidays) before the time of any adjournedmeeting.

The manner in which your shares may be voted depends on how your shares are held. If you own shares of record, meaning that your shares are represented by book entries in your name so that you appear as a shareholder on the shareholder register of the Company maintained by TSX Trust Company (“TSX”) (i.e., you are a registered shareholder), our stock transfer agent, this proxy statement, the notice of AGM and the proxy card will be available to you at www.voteproxy.com by inserting the 12 digit control number on the Notice of Notice and Access of Proxy Materials or proxy card to be provided to you by TSX. You may provide voting instructions by Internet, mobile device or (if you have received paper copies of our proxy materials) by returning a proxy card. If you own Common Shares of record and you do not vote by Internet, mobile device, or proxy at the AGM, your shares will not be voted.

If you own shares in street name (i.e., you are a street shareholder), meaning that your shares are held by a bank, brokerage firm, or other nominee, you are then considered the “beneficial owner” of shares held in “street name,” and as a result, this proxy statement, the notice of AGM and the proxy card will be available to you at www.proxyvote.com by inserting the control number on the instructions to be provided to you by your bank, brokerage firm, or other nominee holding the shares. You may provide voting instructions by the Internet, mobile device or (if you have received paper copies of proxy materials through your bank, brokerage firm, or other nominee) by returning a voting instruction form received from that institution. If you own Common Shares in street name and attend the AGM, you must obtain a “legal proxy” from the bank, brokerage firm, or other nominee that holds your Common Shares in order to vote your Common Shares at the AGM.
