AURA MINERALS ANNOUNCES NORMAL COURSE ISSUER BID AND CONCURRENT BUYBACK PROGRAM FOR BRAZILIAN DEPOSITARY RECEIPTS

The Toronto Stock Exchange has accepted Aura Minerals Inc.'s notice of intention to launch a normal course issuer bid (NCIB) for its issued and outstanding common shares listed on the TSX. The company is also announcing the concurrent launch of a buyback program for its Brazilian depositary receipts (BDRs) which are listed on the B3 SA -- Brasil, Bolsa, Balcao (the B3) -- for the purchase of BDRs by the company, its subsidiaries or investment vehicles.

Rodrigo Barbosa, Aura Minerals' president and chief executive officer, comments: "Aura has consistently delivered sector-leading dividends in the precious metals space over the past three years, surpassing our policy in certain cases, while substantially growing our assets and production profile. The reinstitution of our NCIB and BDR buyback programs reaffirms our commitment to providing value-enhancing growth opportunities for our shareholders."

NCIB

Under the NCIB, Aura Minerals may, if considered advisable, repurchase through the facilities of the TSX and/or alternative Canadian trading systems, from time to time during the currency of the NCIB, up to an aggregate of 2,261,426 common shares (less the number of BDRs purchased under the BDR buyback program), representing 10 per cent of the public float (within the meaning of the rules of the TSX) as of March 6, 2024, subject to the normal terms and limitations of such bids. The company may commence purchases of common shares under the NCIB on March 18, 2024, and the NCIB will remain in effect until the earliest of: (i) March 17, 2025; (ii) the date upon which Aura Minerals acquires the maximum number of common shares permitted under the NCIB; and (iii) the date upon which Aura Minerals provides written notice of termination of the NCIB to the TSX.

Under the TSX rules, the company may purchase up to 2,657 common shares on the TSX during any trading day, which represents 25 per cent of the average daily trading volume of 10,631 common shares on the TSX during the six months ended Feb. 29, 2024, other than purchases made pursuant to the block purchase exception. The actual number of common shares which may be purchased pursuant to the NCIB, and the timing of any such purchases, will be determined by the management of the company, subject to applicable law and the rules of the TSX.

Purchases of common shares under the NCIB are expected to be made by Scotia Capital Inc. through the facilities of the TSX and/or through alternative trading systems in Canada, if eligible, at prevailing market prices. Common shares purchased by the company under the NCIB will be cancelled or held as treasury shares, provided that the conditions set forth in the company's constating documents are satisfied.

The company may enter into an automatic share purchase plan (ASPP) with a designated broker to allow for the purchase of common shares under the NCIB at times when the company would ordinarily not be permitted to purchase shares due to regulatory restrictions or self-imposed blackout periods.

BDR buyback program

Aura Minerals intends to concurrently launch a buyback program for its BDRs which are listed on the B3. Each BDR represents one common share. Under the BDR buyback program, the company may purchase from time to time over 12 months, up to an aggregate of 2,261,426 BDRs (less the number of common shares purchased under the NCIB discussed above), representing 10 per cent of the public float (within the meaning of the rules of the TSX) as of March 6, 2024. Purchases of BDRs under the BDR buyback program are expected to be made by BTG Pactual Corretora de Titulos e Valores Mobiliarios SA through the facilities of the B3.

The BDR buyback program is not intended to (i) discontinue the company's BDR program, or (ii) cancel the company's registration with CVM as a foreign issuer registered as a category A publicly held company. As of March 6, 2024, the company had 72,237,003 issued and outstanding common shares and a public float (within the meaning of the rules of the TSX) of 22,614,260 common shares. The company believes that the purchases are in the best interest of the company and constitute a desirable use of its funds.

The limit for purchases under the NCIB and the BDR buyback program is a combined aggregate limit of 2,261,426 common shares, or 10 per cent of the public float of March 6, 2024.

The company's filings can also be accessed on SEDAR+, at CVM and at B3.
