Aura Minerals Inc. (NASDAQ: AUGO) (B3: AURA33) is pleased to announce Q3 2025 preliminary production results from the Company’s operating mines: Aranzazu, Apoena, Minosa, Almas and Borborema. Total production in Q3 2025, at current prices reached 74,227 gold equivalent ounces ^1,2, 16% higher than Q2 2025 and also 9% higher when compared to Q3 2024. At constant prices, Aura’s quarterly production was a record high, increasing by 17% compared to Q2 2025 and 15% above the Q3 2024. In the 9M 2025, the total production reached 198,347 GEO at current prices. At 2025 Production Guidance Prices³, the 9M 2025 production was 203,592 GEO, 3% above 9M 2024, and on track to achieve the 2025 guidance.

Rodrigo Barbosa, CEO and President commented: “We are pleased to announce a record high quarter of strong performance across our operations, achieving 74,227 gold equivalent ounces (GEO) in Q3, contributing to 265,000 GEO over the last twelve months. For the first nine months of 2025, our production of 203,592 GEO at guidance prices positions us firmly within our 2025 guidance of 266,000–300,000 GEO. A key milestone was the start of commercial production at Borborema, which delivered over 10,000 ounces with a recovery rate above 92%, setting the stage for a steady ramp-up. Delivered on time and on budget, Borborema, as the model of Almas, embodies our Aura 360 commitment to disciplined execution, operational excellence, and sustainable value creation for all stakeholders.”

Q3 2025 | 9M 2025 Highlights:

• At Aranzazu, production reached 21,534 GEO, representing a 3% decrease compared to the previous quarter, resulting mainly from metal prices since higher gold prices negatively impact the conversion to GEO. When compared to Q3 2024, production decreased by 12% due to the sharp increase in gold prices between the periods which also impacted GEO conversion. At constant prices⁴, Aranzazu production was in line when compared to Q2 2025 and 4% higher when compared to the Q3 2024, also due to higher grades of copper and silver. In the 9M 2025, total production decreased by 16% compared to the previous quarter, reaching 64,271, in line with the negative impact of the metals price conversion. At constant prices, Aranzazu produced 62,046 GEO, 4% higher than the same period of the previous year, mainly due to higher grades and commercial molybdenum production.
• At Minosa, production totaled 18,138 GEO, another stable quarter and in line when compared to the previous quarter, resulting from higher grades processed during the quarter and higher recovery rate, which achieved 68%. When compared to the same quarter last year, production decreased by 13%, due to lower stacking in Q3 2025 compared to Q3 2024 due to higher rainfall in Q3 2025. In the 9M 2025, production decreased 9% mainly due to lower ore feed to the plant, reflecting mine sequencing and weather-related constraints, and was consistent with Aura’s expectations.
• At Almas, production reached 15,088 GEO, 17% higher than Q2 2025 (12,917 GEO), driven by higher ore processed volumes and improved mine performance, reflecting the results of the plant expansion. Production was in line when compared to Q3 2024, although the higher ore processed, due to the grades decrease due to mine sequencing. In the 9M 2025, production increased 10%, driven by a higher volume of ore processed, supported by the implementation of larger equipment, which expanded the mine’s operational capacity and enhanced process efficiency.
• At Apoena, production was 9,248 GEO, 13% higher than Q2 2025, driven by higher recovery rates of 95%. Compared with Q3 2024, production increased 15%, primarily because of higher recovery rates and higher processed tonnage feed. In the 9M 2025, production decreased 12% when compared to the same period of the last year, attributable to higher grades in 9M 2024, especially Q1 2024, due to the higher grade of Ernesto pit. So far, 2025’s performance has been above Company expectations.
• At Borborema, production totaled 10,219 GEO, reflecting progress along the ramp-up curve, reaching commercial production in September as planned by the Company.
