Aura Announces Preliminary Record High Production in Q3 2026 and 9M 2026 Production Results
ROAD TOWN, British Virgin Islands, Oct. 09, 2026 (GLOBE NEWSWIRE) -- Aura Minerals Inc. (NASDAQ: AUGO and B3: AURA33) (“Aura” or the “Company”) is pleased to announce Q3 2026 preliminary production results from the Company’s six operating mines: Aranzazu, Apoena, Minosa, Almas, Borborema and MSG (“Mineração Serra Grande”). Total production in Q3 2026, at current prices, reached 95,557 gold equivalent ounces (“GEO”)1, record high production, with 27% increase compared to the previous quarter and 29% higher when compared to Q3 2025. At constant prices2, Aura’s quarterly production increased by 26% compared to Q2 2026 and increased 25% above Q3 2025. In Q3 2026, sales totaled 93,742 GEO, a 20% increase compared to Q2 2026. On a comparable basis (excluding MSG), sales increased 7% compared to the same period last year, mainly due to higher sales at Borborema and Aranzazu. Including MSG, total sales increased 25% YoY.
In the nine months of 2026 (9M 2026), Aura produced 253,131 GEO at current prices and 255,268 GEO at constant prices, representing a 26% increase at constant prices compared to the same period of 2025 and marking the highest 9M production in the Company's history. During the period, Aura sold 253,414 GEO, up 13% excluding MSG and 28% year-over-year with MSG. Over the last twelve months, at current prices, Aura produced 335,198 GEO, another record high and an increase of 27% compared to the twelve-month period of Q3 2025.
Rodrigo Barbosa, CEO and President commented: “As expected, Q3 was a clear step up from Q2, and with the further increase we expect in Q4 we remain on track to meet our full-year guidance. The highlight was MSG, where production rose 85% as the turnaround advanced: underground development moved quickly, and we have already started blending lower-grade stockpile with higher-grade ore from underground under the bottom-up method. Also as planned, Borborema delivered a strong quarter on higher grades and higher throughput, and Aranzazu on higher grades. Into Q4, development at Apoena’s Nosde pit to reach the higher-grade areas is on plan despite the lower Q3 result; at Minosa, stacking volumes had already returned to normal levels during Q3, setting the mine up for improved production in Q4 after the lower result tied to the earlier increase in leach-pad stacking height; Borborema should keep lifting throughput as we debottleneck the filter; at Almas, the plant-capacity expansion is still underway, with higher ore feed already showing through while mine sequencing moves into higher-grade areas; and we will keep advancing the MSG turnaround, alongside improvements at the other operations. At Era Dorada, construction remains on time and on budget, at 13.1% overall physical progress: earthworks on the operational plateau are complete, civil works for the mill and CIP tanks are advancing as planned, and main equipment has been contracted. Underground development is underway, with the contractor 60% mobilized, delineation drilling in progress, and mine refrigeration and underground equipment already on site"
Q3 2026/ 9M 2026 Highlights:
- At Aranzazu, production reached 24,920 GEO in Q3 2026, up 39% QoQ, mainly reflecting higher grades in line with mine sequencing and favorable metal price dynamics in the GEO conversion. The average realized copper price increased 6% QoQ to $6.46/lb (vs. $6.09/lb in Q2 2026), while the average realized gold price decreased 3% to $4,285/oz (vs. $4,416/oz in Q2 2026). Compared with Q3 2025, production increased 16%, also supported by higher grades and favorable metal prices. At constant prices3, Aranzazu production was 35% higher when compared to Q2 2026, explained by higher grades from mine sequencing, while YoY the production was 6% higher. For 9M 2026, production totaled 58,497 GEO at current prices, down 9% from 64,271 GEO in 9M 2025, mainly reflecting lower grades during the first half of the year, partially offset by the strong Q3 performance. At constant prices, production totaled 60,634 GEO, 12% below the 69,040 GEO recorded in 9M 2025, primarily due to lower grades as anticipated. At 2026 Guidance Prices, Aranzazu ended Q3 2026 with a production of 20,552 GEO, 28% higher than Q2 2026. Aranzazu sold 23,250 GEO in Q3 2026, lower than production because the quarter's last shipment was still in transit to the refinery, and 57,232 GEO in 9M 2026.
- At Minosa, production totaled 13,344 GEO in Q3 2026, 7% lower than Q2 2026 and 26% lower compared to Q3 2025, mainly associated with a decrease in ore plant feed. This reduction is still an effect of the increase in stacking level within the leach pad seen in the previous quarter. In 9M 2026, production totaled 45,027 GEO, a 16% decrease compared to 9M 2025 (53,831 GEO), mainly due to these impacts throughout the year. In terms of sales, Minosa sold 13,577 GEO, 11% lower than Q2 2026 and 24% lower than Q3 2025. In 9M 2026, Minosa sold 46,224 GEO, a 13% decrease compared to the 53,189 GEO sold in 9M 2025.
- At Almas, production totaled 14,264 GEO in Q3 2026, down 12% from Q2 2026 and 5% from Q3 2025. The decrease in both periods was primarily driven by lower grades, reflecting the processing of additional ore following the plant expansion and in line with the mine sequencing plan. Plant feed increased 31% compared with Q3 2025 and 3% compared with Q2 2026, reflecting the benefit of plant expansion while recovery remained stable at approximately 88%. Processed grade of 0.74 g/t was in line with the mine sequencing plan, resulting in production 12% lower than Q2 2026 and 5% lower than Q3 2025. Mine sequencing moves into higher-grade areas in Q4. In 9M 2026, production totaled 46,232 GEO, up 12% from 41,107 GEO in 9M 2025, as the higher plant feed enabled by the expansion more than offset the impact of lower grades during the period. Almas sold 14,264 GEO in Q3 2026, in line with production, bringing 9M 2026 sales to 46,232 GEO.
- At Apoena, production totaled 6,865 GEO in Q3 2026, up 20% from Q2 2026, mainly driven by a 27% increase in grade and higher plant feed, reflecting continued advancement of Phase 3 development at the Nosde Pit. During the quarter, the operation completed access to the main higher-grade areas of Phase 3, which were already feeding the plant late in the quarter and will be the primary source of ore in Q4. Compared with Q3 2025, production decreased 26%, primarily due to lower plant feed and lower recovery rates. In 9M 2026, total production was 20,094 GEO, a 24% decrease compared to the same period of last year (26,343 GEO), mainly due to lower ore plant feed and lower grades. In the quarter and in 9M 2026, Apoena sold the same amount as it produced.
- At Borborema, production totaled 22,842 GEO, a quarterly record for the operation and 60% higher than the previous quarter, representing approximately 24% of Aura’s total production in Q3 2026., The increase was driven by higher grades, up 42% (from 1.16 g/t to 1.65 g/t), reflecting access to higher-grade areas in line with the mine plan. With the improvement of filtering performance, ore plant feed was up 14% QoQ. In 9M 2026, total production was 54,194 GEO. In the quarter, Borborema sold 22,454 GEO, also a quarterly record, totaling 53,602 GEO in 9M 2026.
- At MSG, production totaled 13,321 GEO, an 85% increase compared to Q2 2026. This increase in production was driven by higher grades, from 0.90 g/t in Q2 2026 to 1.19 g/t in Q3 2026, and higher ore plant feed that increased 28% QoQ, and also an improved recovery +1.9 p.p., to 89.6%. Both the higher grade and the higher ore plant feed were results of the mine's turnaround, with the underground infrastructure and the transition to the bottom-up method advancing according to plan. Following the first half of 2026 focused on mine development, the contribution of these areas to plant feed is expected to increase gradually, in line with the plan to bring MSG to full capacity. In 9M 2026, production reached 29,087 GEO. Regarding sales, MSG sold 13,332 GEO in Q3 2026, totaling 30,030 GEO in 9M 2026.

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 and copper realized from sales at the Aranzazu Mine during the relevant period.
2 Applies the metal
sale prices in Aranzazu realized during Q3 2026: Copper price = US$6.46/lb; Gold Price = US$4,285/oz; Silver Price = US$63.25/oz and Molybdenum
Price = US$33.05/lb.
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.
4
The total may not add due to rounding.
5 Applies the metal sale prices in Aranzazu realized at each relevant quarter.
6
Commercial production at Borborema started in the second half of 2025.
