AURA DECLARES COMMERCIAL PRODUCTION AT ALMAS

Commercial production has been achieved at Aura Minerals Inc.'s Almas gold mine, effective as of Aug. 31, 2023. Almas mill is operating above 100 per cent of the design capacity, processing 4,000 tonnes per day, with recoveries consistently above 90 per cent and ranging up to 92 per cent. Approximately 4,661 ounces of gold were produced in August, with gross revenues of approximately $9-million (U.S.) recognized in the month.

Almas achieved full capacity at the mill in only five months after commissioning of the project, significantly ahead of benchmarks.

Consistent with Aura's strategy to start small and optimize upfront capital expenditures, the company is now focused on investing in increasing the mill's capacity from 1.3 million tons per year to 1.5 million tons per year. During the remainder of 2023, Aura is expected to invest about $3.5-million (U.S.) for such production capacity at Almas. The capacity increases are expected to be fully implemented at the beginning of 2024 and contribute to an increased annual gold production of approximately 15 per cent compared with Almas's feasibility study.

Rodrigo Barbosa, Aura's president and chief executive officer, commented: "We are very proud to declare commercial production at Almas. We have not only built it on budget and in only 16 months during challenging years, but we have also now ramped up in record time, making us one of the world's leading benchmarks. We are also now investing on exploration targeting new resources and reserves while we are encouraged by the potential to increase the plant's capacity, to bolster production more than we initially projected, with expected results already for 2024."
