Aura Announces Q3 2024 Production Results, the Fifth Consecutive LTM Production Increase and on Track to Meet the Company’s 2024 Guidance

ROAD TOWN, Oct. 10, 2024 - Aura Minerals Inc. (TSX: ORA, B3: AURA33 and OTCQX: ORAAF) ("Aura" or the "Company") announces Q3 2024 preliminary production results from the Company's four operating mines: Aranzazu, Apoena (EPP), Minosa (San Andres), and Almas. Total production in Q3 2024 reached 68,246 gold equivalent ounces ("GEO")¹, 10% above the second quarter of 2024 and 10% above the same period last year at constant metal prices. The highlights of the quarter were the performance of Almas, where production stabilized at 15k GEO after a contractor replacement in Q2 2024, reaching what the Company considers a consistent level for the operation, and Minosa, which recorded another quarterly production growth. This quarter, Aura achieved a new record high LTM production, with 269,953 GEO produced in the period.

For the nine months of 2024, Aura's total production was 200,758 GEO at current prices, on track to meet the 2024 Production Guidance of 244,000 - 292,000 GEO.

Q3 2024 Highlights

• At Aranzazu, Aura recorded another stable quarter, with production totaling 24,486 GEO, reflecting an 8% increase over Q2 2024 and a 3% decrease compared to Q3 2023, at constant prices, and according to expectations. The improved recovery rates, driven by higher ore grades and due to mine sequencing, contributed to this quarterly increase. Cumulative production for the first nine months of 2024 (9M24) reached 70,492 GEO at constant prices, remaining stable compared to the same period in 2023 (9M23).
• At Minosa (San Andres), production totaled 20,750 GEO, reflecting an 8% increase over the previous quarter and an 18% increase compared to Q3 2023. This quarterly improvement was largely attributed to a higher stacking of ounces and better ore grades during the period. This marks another quarter of production growth, driven by Aura's ongoing focus on optimizing operational efficiency, and due to a rainy season that was weaker than expected for the period, increasing the productivity at the mine and at the plant. For the first nine months of 2024 (9M24), cumulative production reached 59,078 GEO, a 23% increase compared to the same period in 2023 (9M23).
• At Almas, production reached 14,975 GEO, representing a 42% increase compared to the previous quarter. This increase in output was driven by higher productivity and operational efficiency following the transition to a new contractor in the prior quarter. The new contractor achieved the expected ramp up and stabilized production at an average of 5,000 GEO per month since June 2024. For the first nine months of 2024 (9M24), cumulative production totaled 37,450 GEO. This performance further reinforces the Company's confidence in achieving its 2024 production guidance.
• At Apoena (EPP), production was 8,035 GEO, down 19% from Q2 2024 and 28% from Q3 2023. Production was below the Company's expectations due to lower grades processed during the quarter, along with a reduction in ore recovery caused by a temporary delay in obtaining the environmental permit to expand the Nosde pit and access higher-grade ore, which will be recovered in 2025. Additionally, production in Q3 2024 was affected by lower mill throughput compared to Q3 2023, driven lower performance in the mill due to harder rock ore from the mined area - an expected outcome given the characteristics of the production area. In the first 9 months of 2024, production totaled 30,052 GEO, 2% lower than the first 9 months of 2023.

Rodrigo Barbosa, Aura's President and CEO commented, "We entered the second half of 2024 maintaining our growth trajectory, with total production reaching 201K GEO accumulated in the year, a 20% increase compared to the same period in 2023, keeping us well-positioned to meet the upper half of our annual production guidance. Despite the challenges with Apoena, operations at Aranzazu and Minosa remained strong and consistent, while production at Almas was successfully stabilized, contributing to our fifth consecutive LTM production increase. Construction of Borborema is now above 50% complete, progressing on schedule and within budget. The ramp-up phase is expected to commence in Q1 2025, setting the stage for a strong and promising year ahead when we will continue to grow our LTM production through 2025."

¹ 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.

Production Results

Preliminary GEO^2,3 production volume for the three months ended September 30, 2024, compared to the previous quarter and the same period in the previous year is presented below:

Production in the last twelve months ("LTM") up to September 30, 2024, was 269,953 GEO, increasing for the fifth consecutive quarter, as a result of production from Almas and consistent improvements in Minosa's production. This was the highest LTM production in the Company's history. The chart below displays the consolidated quarterly GEO production measured at current and constant prices since Q3 2022, as well as the LTM at the end of each reporting period:
