A Transformative Year for Reserve Growth

Aura Minerals has reported a massive expansion of its resource and reserve base, effectively doubling its proven and probable reserves during the 2025 fiscal year. According to a company update released Wednesday, total reserves now stand at 7.22 million GEOs, up from 3.44 million in the previous reporting period. This growth spans six operating mines and two major development assets across the Americas, signaling a robust long-term production profile. The company attributes this surge to a combination of aggressive exploration drilling, refined geological modeling, and favorable economic shifts, including rising gold prices that allowed for expanded pit designs.

Brazilian Assets Drive 170 Percent Expansion

The primary engine of this growth has been the company’s Brazilian portfolio. The Borborema mine, located in the Seridó region of Rio Grande do Norte, saw its reserves jump by 170% following its transition to commercial production in September 2025. A new feasibility study highlighted the impact of higher gold prices and improved geological interpretations in expanding the mine's potential. Additionally, successful drilling campaigns at the Almas mine led to the inclusion of new underground reserves, further solidifying the company's footprint in one of South America's most productive mining jurisdictions.

Strategic Acquisition of Serra Grande

A significant portion of the reserve increase was realized through the strategic acquisition of the Mineração Serra Grande mine from AngloGold Ashanti in June 2025. This addition provided an immediate boost to the company's operating capacity and total resource tally. CEO Rodrigo Barbosa noted that the acquisition, combined with organic exploration efforts, has created a "significantly strengthened production foundation" that will support the company’s ambitious growth targets for the remainder of the decade. Measured and indicated resources also saw a 26% uptick, while inferred resources skyrocketed by more than 200% to 3.92 million GEOs.
