Aura Minerals Inc. (NASDAQ: AUGO) (B3: AURA33) is pleased to announce Q2 2026 preliminary production results from the Company’s six operating mines: Aranzazu, Apoena, Minosa, Almas, Borborema and MSG. Total production in Q2 2026, at current prices, reached 75,437 gold equivalent ounces¹, an 8% decrease compared to the previous quarter and 18% higher when compared to Q2 2025. At constant prices², Aura’s quarterly production decreased by 9% compared to Q1 2026 and increased 16% above Q2 2025. In Q2 2026, sales totaled 77,764 GEO, a decrease of 4% compared to Q1 2026, while compared to the same period of the last year, it increased by 25%, mainly due to better sales at Almas, a Borborema under commercial production and the acquisition of MSG.

In the six months of 2026 (H1 2026), Aura produced 157,574 GEO at current prices and 158,448 GEO at constant prices, representing a 27% increase compared to the same period of 2025 and marking the highest first-half production in the Company’s history. During the period, Aura sold 159,129 GEO, up 29% year-over-year. Over the last twelve months, Aura produced 313,868 GEO, an increase of 21% compared to the corresponding prior twelve-month period.

Rodrigo Barbosa, CEO and President commented: “We are pleased to report that our Q2 production was in line with expectations, contributing to record-high output for both the first half of the year and the last twelve months. While Q2 production was 75.4 thousand GEO — lower than Q1 as expected — we remain firmly on track with our full-year guidance. Equally important to our current results are the strategic initiatives and growth projects that position Aura to exceed 600,000 GEO annually in the coming years. Key highlights include: (i) At MSG, we continue to invest in underground infrastructure and primary development to transition the mining method from top-down to bottom-up; (ii) Era Dorada is now in full construction following recent Board approval; (iii) Almas delivered higher production thanks to increased plant capacity from the ongoing expansion; (iv) Apoena open-pit mine development is progressing according to plan, setting the stage for higher grades in the second half of the year; (v) Borborema advances on its technical studies for the planned expansion, supported by the road relocation agreement with DNIT; and (vi) exploration and technical studies continue to advance at Matupá and Serra da Estrela, further strengthening our organic growth pipeline.”

Q2 2026 Highlights:

• At Aranzazu, production reached 17,882 GEO, representing a 14% increase compared to the previous quarter, primarily driven by metal price dynamics regarding GEO conversion, considering that the average gold realized price declined 9% QoQ to $4.416/oz (vs. $4.850/oz in Q1 2026), while copper outperformed, with the average realized price increasing 5% to $6.09/lb (vs. $5.80/lb in Q1 2026). When compared to Q2 2025, production decreased by 20% due to lower production driven by the mine plan. At constant prices³, Aranzazu production was 8% higher when compared to Q1 2026, explained by higher grades from mine sequencing, while YoY the production was 24% lower. In H1 2026, total production decreased by 21% compared to the previous year at current prices, reaching 33,576 GEO. At constant prices, Aranzazu produced 34,450 GEO, also 21% lower compared to the same period of the previous year of 43,645 GEO, mainly due to lower grades as expected in the mine sequencing. At 2026 Guidance Prices³, Aranzazu ended Q2 2026 with a production of 16,043 GEO, 6% higher than Q1 2026. Aranzazu sold 17,764 GEO in Q2 2026 and 33,982 GEO in H1 2026.
• At Minosa, production totaled 14,284 GEO in Q2 2026, 18% lower than Q1 2026 and 21% lower compared to Q2 2025, which were 20% lower YoY and 8% lower QoQ, associated with the increase in stacking level within the leach pad and lower ore plant feed. In H1 2026, production totaled 31,683 GEO, 11% decrease compared to H1 2025 (35,693 GEO), mainly due to these impacts in Q2 2026. In terms of sales, Minosa sold 15,190 GEO, 13% lower than Q1 2026 and 15% lower Q2 2025. In H1 2026, Minosa sold 32,647 GEO, an 8% decrease compared to the 35,362 GEO sold in H1 2025.
• At Almas, production reached 16,130 GEO, 25% higher than Q2 2025, driven by higher ore processed volumes due to the expansion project of the plant’s operational capacity. This effect also positively impacted production when compared to Q1 2026, which increased 2%. In H1 2026, production totaled 31,968 GEO, 23% increase compared to H1 2025 (26,018 GEO), driven mainly by 20% higher ore moved volumes and 30% higher ore plant feed, reflecting the results of the plant expansion. In the quarter, Almas sold 17,920 GEO, higher than production as the last shipment of the previous quarter was in transit and was considered as a Q2 2026 sale volume. In the H1 2026, Almas sold 31,968 GEO.
• At Apoena, production was 5,704 GEO, 24% lower than Q1 2026, due to a grade decrease of 26%, from 0.8 g/t to 0.6 g/t, as expected from the mine sequencing and in line with the Company’s plan. Compared with Q2 2025, production also decreased by 31%, primarily because of lower grades and lower recovery rates. In H1 2026, total production was 13,229 GEO, a 23% decrease compared to the same period of last year, mainly due to lower ore plant feed and lower grades. In the quarter and semester, Apoena sold the same amount as produced. This result is in line with Company`s plan to achieve higher grades in the Nosde Pit during the second semester.
• At Borborema, production totaled 14,251 GEO, 17% lower than the previous quarter, driven by lower grades, which declined 18% (from 1.41 g/t to 1.16 g/t), due to mine sequencing and as expected. In H1 2026, the total production was 31,352 GEO, higher than the same period of last year, considering that the commercial production of Borborema started in Q2 2025. In the quarter, Borborema sold 13,996 GEO, totaling 30,605 GEO in H1 2026.
• At MSG, production totaled 7,186 GEO, a 16% decrease compared to Q1 2026, driven by lower grades (from 1.54 g/t in Q1 2026 to 0.90 g/t in Q2 2026) but in line with the Company’s expectations under the MSG turnaround strategy. During the quarter, the Company also advanced, as expected, its operational improvement strategy, with increased development of mine infrastructure and primary development to invert mine method to bottom up. In H1 2026, production reached 15,766 GEO. Regarding sales, MSG sold 7,190 GEO in Q2 2026, totaling 16,698 GEO in H1 2026.
