Aura Announces Preliminary Q1 2026 Production Results, another record high and on track with the Company Guidance

ROAD TOWN, British Virgin Islands, April 10, 2026 (GLOBE NEWSWIRE) — Aura Minerals Inc. (NASDAQ: AUGO and B3: AURA33) (“Aura” or the “Company”) is pleased to announce Q1 2026 preliminary production results from the Company’s six operating mines: Aranzazu, Apoena, Minosa, Almas, Borborema and MSG (“Mineração Serra Grande”). Total production in Q1 2026, at current prices, reached 82,137 gold equivalent ounces (“GEO”)¹, another high record quarter production, above the previous quarter and also 37% higher when compared to Q1 2025. At constant prices², Aura’s quarterly production increased by 1% compared to Q4 2025 and 41% above Q1 2025. On track with the Company’s Guidance. During the quarter, Aura sold 81,364 GEO, a slight increase compared to the previous quarter.

Rodrigo Barbosa, CEO and President commented: “We delivered another record production quarter in Q1 2026, reaching 82.1 thousand GEO. Despite dedicating efforts to essential underground infrastructure upgrades at MSG and lower production in Apoena and Borborema due to mine sequencing. For the second semester, we expect higher production at Aranzazu, Apoena, MSG and Borborema, while Almas and Minosa remain stable — very much in line with our annual guidance. Looking to the coming years, we continue advancing the Borborema expansion, the Almas underground development, the updated Feasibility Study for Matupá with its recently published additional ounces, and early works at Era Dorada — all supporting our next phase of growth toward over 600,000 GEO annually.”

Q1 2026 Highlights:

• At Aranzazu, production reached 15,694 GEO, representing a 17% decrease compared to the previous quarter, resulting partially from metal prices since higher gold prices negatively impact the conversion to GEO. When compared to Q1 2025, production decreased by 23% also due to the sharp increase in gold and silver prices between the periods which also impacted GEO conversion. This result is in line with the Company’s mine plan and according to mine sequencing; production is expected to increase towards the last quarters of the year. At constant prices³, Aranzazu production was 15% lower when compared to Q4 2025 and 16% lower compared to Q1 2025, due to lower grades of copper (from 1.45% to 1.15%), silver (from 21g/ton to 17g/ton) and gold (from 0.8g/ton to 0.7g/ton), due to mine sequencing and according to the Company’s plan. During the quarter, Aranzazu sold 16,218 GEO, 9% lower than last quarter. Sales exceeded production due to the timing of revenue recognition of the final 2025 shipment.
• At Minosa, production totaled 17,399 GEO in Q1 2026, 2% lower than Q4 2025 and in line with Q1 2025, mainly as a result of lower gold extraction during the period, but consistent with Aura’s expectations. In terms of sales, Minosa sold 17,456 GEO, 3% above Q4 2025 and same level of Q1 2025, mainly due to the shipping schedule of gold from December 2025.
• At Almas, production reached 15,838 GEO, representing a 21% increase compared to Q1 2025 and remaining in line with Q4 2025 levels. This performance was driven by higher ore throughput and improved mine performance, reflecting the benefits of the plant expansion, which more than offset lower grades during the period as result of mine sequencing. In the quarter, Almas sold 14,048 GEO, lower than production as the last shipment of the quarter is in transit to the refinery.
• At Apoena, production was 7,525 GEO, 20% lower than Q1 2025 and 16% than Q4 2025, primarily driven by lower ore throughput and recovery rates, in line with the Company’s mine plan. According to mine sequencing, production is expected to increase towards the last quarters of the year. In Q1 2026, Apoena sold 7,525 GEO, consistent with its mine sequencing and lower grades during the fist half of the year.
• At Borborema, production totaled 17,101 GEO, representing a 9% increase compared to the previous quarter, reflecting continued progress along the ramp-up curve and higher milling throughput. In the quarter, Borborema sold 16,609 GEO, a 5% increase compared to the previous quarter.
• At MSG, production totaled 8,580 GEO, with sales of 9,508 GEO. As part of the ongoing turnaround at the mine, Aura dedicated Q1 to critical underground infrastructure upgrades — a fundamental step that will continue throughout the year and enable more consistent development and higher production levels in the coming years.

¹ Gold equivalent ounces, or GEO, is calculated by converting the production of silver, copper and molybdenum into gold using a ratio of the prices of these metals to that of gold. The prices used to determine the GEO are based on the weighted average price of silver, copper and molybdenum realized from sales at the Aranzazu Mine during the relevant period.
² Applies the metal sale prices in Aranzazu realized during Q1 2026: Copper price = US$5.80/lb; Gold Price = US$4,850/oz; Silver Price = US$83.12/oz and Molybdenum Price = US$25.65/oz.
³ Constant Price” is a method of converting our copper, silver and molybdenum production or sales volume into GEO based on fixed metal prices. This approach eliminates the impact of metal price fluctuations, when comparing production or sales figures across different periods. Using constant prices allows for a consistent and meaningful comparison of gold equivalent production or sales over time. It ensures that differences in GEO production or sales between two periods reflect changes in actual physical metal production or metal sales and not changes due to fluctuations in commodity prices among the periods. GEO at constant price for previous period, to be compared to GEO for current period, is copper production or sales volume previous period multiplied by copper prices current period plus silver production or sales volume for previous period multiplied by silver prices from current period plus molybdenum production or sales volume for previous period multiplied by molybdenum prices from current period divided by gold price for current period.

¹ The total may not add due to rounding.
² Applies the metal sale prices in Aranzazu realized at each relevant quarter.
