Aura Announces Third Quarter 2022 Production Results

ROAD TOWN, Oct. 11, 2022 - Aura Minerals Inc. (TSX: ORA) (B3: AURA33) ("Aura" or the "Company") is pleased to announce production results from the Company's three producing operations for the third quarter of 2022. Total production reached 58,175 gold equivalent ounces ("GEO")¹ during Q3 2022.

Highlights

• Total production in GEO increased by 5% when calculated based on current prices and by 8% at constant prices relative to Q2 2022.
• Aranzazu concentrate production increased 6% relative to Q2 2022 as a result of consistently high production rates above 100,000 tons per month and achieving a quarterly record of 104,400 tons monthly average of material processed at the plant. Production on a GEO basis was impacted by lower copper prices in the quarter.
• At EPP, the mine operation focused on phase II of the Ernesto pit resulting in higher grades. The Company expects that this will drive significantly higher production in Q4 2022. For Q3 2022, the Company also focused on blending mid/low grade material in order to reduce inventory, thus optimizing cashflows. Production was slightly better than management's expectations, achieving close to 18,000 oz of gold; production ramped up in September 2022, achieving 8,378 ounces. Aura expects EPP to deliver strong production in Q4 2022.
• Production at San Andres was below management's expectations. In July of 2022, Aura engaged a new contractor for mine operations, which is expected to increase production levels and drive down cash costs in the coming quarters. During Q3 2022, heavy rains, above the historical average for the quarter, and lower productivity levels as result of the negotiations and transition to a new mine contractor, had a negative impact on production. Aura expects San Andres production levels to increase in Q4 2022.

Rodrigo Barbosa, the Company's President and CEO, noted, "Despite the weather, lower copper prices and lower productivity in Honduras, this quarter we increased our production by 5% compared to Q2 2022. We look forward to strengthening our output across all three operations as we move into the fourth quarter, particularly at EPP with higher grades and San Andres where operational efficiencies are expected to take effect."

Production Results

Preliminary GEO production volume for the three months ended September 30, 2022, when compared to the previous quarter and the same period of 2021 is shown below:

The last twelve months' production (LTM) exceeded 250,000 GEO at the end of Q3 2022, when production from Gold Road, which had its operation suspended during Q4 2021, is excluded. LTM has remained stable at constant prices compared to the previous quarters.

The chart below shows the quarterly consolidated GEO production measured in current and constant prices since the third quarter of 2020, as well as the LTM at the end of each reporting period:

A summary of the performance by each operating mine during the Q3 2022 is set out below:

EPP Mines: Production was 18% above the same quarter of 2021 and 43% above Q2 2022. Grades reached 1.43 g/t Au with the focus on Phase II of the Ernesto deposit, which also provided a softer mineral and enabled a 18% increase in material processed compared to previous quarter.

San Andres: Production was 20% below the same quarter of 2021 and 16% below Q2 2022 mainly due to lower mine production as result of a new mine contractor and heavy rains. Material mined was 25% less than Q2 2022. For Q4 2022, the Company is focusing on the upper zone of Esperanza, which it expects will provide higher grades with oxidized material.

Aranzazu: Concentrate production was 9% above the same quarter of 2021 and 6% above Q2 2022, partially offsetting a reduction in copper sale price, which was 18% below the same quarter of 2021 and also 18% below the previous quarter. Copper production was 12% above the same quarter of 2021 and 10% above the previous quarter, as a result of higher head grade and better mine and plant performance.

Additionally, as a result of a 19% drop in the copper price during the period, the Company anticipates earnings to be affected by provisional pricing adjustments in accordance with the offtake agreement⁶ between Aranzazu and Trafigura México, S.A. de C.V. Aura will provide additional discussion and analysis regarding its Q3 2022 production and sales when the Company reports its quarterly results on November 8, 2022.

¹ Gold equivalent ounces, or GEO, is calculated by converting the production of silver and copper 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 silver and copper realized from sales at the Aranzazu Complex during the relevant period.
