Mr. Rodrigo Barbosa reports

AURA DECLARES COMMERCIAL PRODUCTION AT BORBOREMA

Commercial production has been achieved at Aura Minerals Inc.'s Borborema gold mine effective as of Sept. 22, 2025. The Borborema mill is operating above 80 per cent of the design capacity, processing 4,500 tonnes per day, with recoveries consistently above 90 per cent and ranging up to 92 per cent. Until now Borborema has already sold more than 10,000 ounces of Gold.

Rodrigo Barbosa, Aura's president and chief executive officer, commented: "We are proud to announce commercial production at the Borborema mine, six months after start-up, after 19 months of construction, and with no lost-time incidents (LTI). Like our Almas project, Borborema was delivered on time and on budget, reinforcing our commitment to operational excellence. This is our fifth operating mine and is expected to be our second-largest producer. As an upside, the project reserves are 812,000 oz of gold, with mineral resources in indicated category at approximately 1.18 million oz of gold (exclusive of mineral of reserve). This provides strong potential for higher returns and increased reserves. Finally, Borborema exemplifies how Aura combines operational excellence, safety and sustainability, using 100-per-cent treated greywater from Currais Novos, excluding rainwater, for all water needs at the mine and plant, reflecting our environmentally responsible approach".

About Borborema

Borborema project is a greenfield open pit gold project, located in the municipality of Currais Novos, Rio Grande do Norte state, in the northeast of Brazil. Aura completed a feasibility study in August, 2023, for this project, which indicated anticipated production of 748,000 ounces of gold over an 11.3-year mine life, with possibilities for even greater output. This project has probable mineral reserves of 812,000 oz gold, and an exclusive indicated mineral resource profile that consists of 37.7 Mt (million tonnnes) at average grades of 0.97 gram per tonne Au for 1,178,000 oz of gold and 10.9 Mt at average grade of 1.13 g/t Au for 394,000 oz of inferred mineral resources. Aura have undertaken initial measures to start obtaining permits to move a road which crosses a portion of the deposit. Upon the road's successful relocation, there would exist the potential to convert additional indicated mineral resources into probable mineral reserves (in addition to the current probable mineral reserves), depending on certain factors, such as gold price and exchange rate, among others.
