Aura Minerals Inc. (TSX: ORA) (B3: AURA33) (OTCQX: ORAAF) is pleased to announce Q2 2025 preliminary production results from the Company’s operating mines: Aranzazu, Apoena, Minosa, Almas and Borborema. Total production in Q2 2025 reached 64,033 gold equivalent ounces^1,2, 7% higher than Q1 2025 and in line when compared to Q2 2024. At constant prices, Aura’s production increased by 9% compared to both Q1 2025 and Q2 2024.

Q2 2025 Highlights:

• At Aranzazu, production reached 22,281 GEO, representing a 9% increase compared to the previous quarter, resulting from higher grades and better recoveries, despite the increase in gold prices which negatively impacted the conversion to GEO. When compared to Q2 2024, production decreased by 10% due to the sharp increase in gold prices between the periods which also impacted GEO conversion. At constant prices³, Aranzazu production increased by 17% when compared to Q1 2025 and 15% when compared to the Q2 2024, also due to higher grades.
• At Minosa, production totaled 18,039 GEO, up 2% when compared to the previous quarter, resulting from higher grades processed during the quarter due to mine sequencing. When compared to the same quarter last year, production decreased by 6% and was in line with the Company’s expectations.
• At Almas, production reached 12,917 GEO consistent with Q1 2025 (13,101 GEO). Compared to Q2 2024, production increased by 22%, driven by higher ore throughput and improved mine performance, reflecting the benefits of the plant expansion and the transition to the new mine contractor during Q2 2024.
• At Apoena, production was in line with expectations and at 8,219 GEO, a 17% decrease from Q2 2024, primarily due to the mine’s investment phase and lower ore grades. Compared to Q1 2025, production decreased 7%, consistent with the mine plan, as lower-grade ore was mined. Despite this decrease, production remains in line with the Company`s full year 2025 expectations. Pre-stripping activities are underway while we push back the Nosde and Lavrinha mines to regain access to higher volume and higher grades by end of 2026 at Nosde Phase III.
• At Borborema preliminary production totaled 2,577 GEO following the project’s first gold pour. Aura believes that Borborema remains on track to declare commercial production by the end of Q3 2025.
