Consistent with the 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 US$3.5 million 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% compared to Almas’ Feasibility Study.

Rodrigo Barbosa, Aura’s President, and CEO 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.”
