AURA MINERALS SUCCESSFULLY STARTS RAMP-UP AT BORBOREMA, ON SCHEDULE, WITHIN BUDGET, AND SETTING AN ESG BENCHMARK

Production ramp-up at Aura Minerals Inc.'s Borborema mine has begun. The mine and plant are currently in operation, and the company expects to achieve commercial production by the third quarter of 2025. Borborema is poised to become a cornerstone asset for Aura, expected to have the second-highest annual production among the company's five operations currently at production stage, once commercial production is achieved. Aura envisions Borborema to be a strong economic driver and a testament to its strategic growth in Brazil's mining landscape.

Rodrigo Barbosa, president and chief executive officer, commented: "The start of production at Borborema marks a proud milestone for Aura -- our fifth mining operation and second greenfield project, projected to be one of our lowest-cost mines, built on time and on budget in just 19 months with zero lost-time incidents. This success showcases our strategy of creating simple, scalable and efficient projects that are easy to build and run, setting the stage for Aura as a reliable operator and new mine builder. Borborema stands as a global ESG [environmental, social and governance] benchmark, driven by innovations like using grey water from the nearby municipality and renewable energy, fully embodying our Aura 360 commitment to responsible operations.

"We are also pleased to highlight the strong economic fundamentals of the mine, which delivers an after-tax internal rate of return (IRR) of 41.8 per cent on an unleveraged basis and 81.4 per cent considering 50-per-cent leverage, based on a gold price of $2,600 (U.S.) per ounce. Notably, these figures do not yet reflect the significant upside potential from future reserve growth, particularly once the road relocation is executed."

The 100-per-cent-owned Borborema project is an open-pit gold mine, located in the municipality of Currais Novos, northeastern Brazil. On Aug. 30, 2023, Aura released a feasibility study indicating an anticipated production of 748,000 ounces of gold over an 11.3-year life of mine, with possibilities for even-greater output in a deposit with over two million contained ounces of gold in the indicated mineral resource category. Aura holds 100 per cent of Borborema Inc.'s shares, the owner of Borborema. According to the company's guidance released on Feb. 27, 2025, available on SEDAR+, the company expects 2025 production at Borborema to be between 33,000 and 40,000 ounces of gold.

Borborema's highlights:

• Annual production -- average of 83,000 ounces per year for the first three years (2025 production guidance of between 33,000 and 40,000 ounces);
• Life of mine -- 11 years, based on existing proven and probable mineral reserves;
• Submitted approval of the road relocation -- relocating the road has the potential to convert significant additional indicated mineral resources (exclusive of current mineral reserves) into mineral reserves;
• Growing work force contributing to region and community development -- Borborema employs approximately 2,184 personnel, directly and indirectly, with 68 per cent currently hired from the local community and efforts to expand this percentage, encouraging entrepreneurship and regional economic growth. Operators training, focused on local community, was concluded, building a skilled local work force for the plant operation.
