AURA ANNOUNCES Q1 2025 PRODUCTION RESULTS

Aura Minerals Inc. has released Q1 2025 preliminary production results from the company's four operating mines: Aranzazu, Apoena, Minosa and Almas. Total production in Q1 2025 reached 60,087 gold equivalent ounces (GEO), 9 per cent below the fourth quarter of 2024 and a 7-per-cent decrease compared with the same period last year at constant metal prices. The company remains on track to achieving its 2025 guidance of 266,000 to 300,000 GEO.

During the quarter, Aura commenced operations at its fifth mine, Borborema, among the company's largest and lowest-cash-cost operations. As mine commenced operations at the end of March, 2025, no production volumes were recorded in the first quarter. Borborema was completed on schedule, within 19 months, and on budget, with a total capex (capital expenditure) of $188-million (U.S.). Aura expects to produce between 33,000 and 40,000 ounces from this operation in 2025.

Q1 2025 highlights:

• At Aranzazu, production reached 20,456 GEO, representing a 10-per-cent decrease compared with Q4 2024 at constant prices. This reduction was primarily due to a 7-per-cent decrease in ore milled, as a result of mine sequencing and increased scheduled downtime for maintenance. Additionally, copper recovery was negatively impacted by the processing of hangingwall material containing high clay content. When compared with Q1 2024, production decreased by 5 per cent at constant metal prices, also due to a 5-per-cent reduction in the volume of ore milled and higher increased scheduled downtime.
• At Minosa, production totalled 17,654 GEO, reflecting an 8-per-cent decrease when compared with the previous quarter. This decline was mostly caused by lower ore grades due to mine sequencing as anticipated in the 2025 production guidance. When compared with the same quarter last year, production decreased by 8 per cent, primarily due to two factors: a 5-per-cent reduction in ore plant feed and lower ore grades, as assumed on the guidance for this year.
• At Almas, production reached 13,101 GEO, representing a 21-per-cent decrease when compared with the previous quarter. This performance aligns with the mine's production plan for this quarter, which anticipated a higher movement of waste during Q1, leading to a higher waste-to-ore ratio and lower grades. When compared with Q1 2024, production increased by 10 per cent. This improvement was primarily due better performance at the mine and at the plant, as demonstrated throughout the second semester of 2024.
• At Apoena, production reached 8,876 GEO, a 25-per-cent increase from Q4 2024, primarily due to a 16-per-cent rise in ore grades and a 6-per-cent improvement in metal recovery. When compared with Q1 2024, production saw a 27-per-cent decline, driven by a 27-per-cent decrease in grades for the quarter. This drop is attributable to high grades in Q1 2024 due to mine sequencing and according to the plan.

Rodrigo Barbosa, Aura's president and chief executive officer, commented: "We started 2025 positively with the investment in Borborema construction was concluded on time and on budget. Now, the ramp-up should finish by Q3 2025, and then Borborema will become a key asset for Aura, with one of the company's largest resource bases and lowest cash costs in our portfolio. The first quarter of 2025 went well, aligning with our yearly plan and keeping production on track to hit our goals. We're excited about our progress, with an output of 33,000 to 40,000 GEO projected for 2025 from Borborema. This strong start sets us up nicely to meet our yearly targets and boosts our confidence in growing and improving our operations."

Note: Gold equivalent ounces, or GEO, is calculated by converting the production of silver, copper and gold into gold using a ratio of the prices of these metals to that of gold. The prices used to determine the gold equivalent ounces are based on the weighted average price of gold, silver and copper realized from sales at the Aranzazu complex during the relevant period.
