ROAD TOWN, British Virgin Islands, April 13, 2026 (GLOBE NEWSWIRE) -- Aura Minerals Inc. (NASDAQ: AUGO, B3: AURA33) (“Aura” or the “Company”) is pleased to announce that its Board of Directors (the “Board”) has approved the development of the Era Dorada Project (“Era Dorada” or the “Project”), marking another significant milestone in the Project’s advancement. In addition to the core project approval, Aura has secured budget authorization for an advanced water treatment system, with plans to pursue all necessary government permits and approvals. This will enable the delivery of purified, potable water to the local community, further demonstrating Aura’s steadfast dedication to environmental stewardship, sustainable social impact, and responsible mining practices.

Total capital expenditures for the Era Dorada Project are estimated at US$382.0 million.and the project is expected to commence operations in the first half of 2028. Average annual gold production estimated at 111,000 ounces during the first four years of the Project, with an estimated life of mine of 17 years, based on mineral reserves estimated in accordance with S-K 1300. A copy of the Era Dorada Feasibility Study has been filed with the United States Securities and Exchange Commission (SEC) via EDGAR and is available at www.sec.gov and with the Brazilian Securities Commission (Comissão de Valores Mobiliários) (CVM) at www.cvm.com.br and is also available on Aura’s investor relations website.

Rodrigo Barbosa, Aura’s President and CEO commented, “After more than a year and over 1,000 hours of dialogue with local communities, authorities, and federal regulators, we converted the project to underground mining and approved additional investments. This ensures we not only do no harm but go beyond and create positive value for the communities and environment. Water quality is a key local concern, so Aura has approved a three-part plan: (i) Invest in engineering, infrastructure, and equipment to build and operate a plant that purifies local water to drinking quality, supplying it to communities through partnerships with authorities; (ii) Recycle and reuse 100% of the water in our plant processes; and (iii) Collaborate with local government and regulators to develop a plan to treat urban wastewater, helping clean the rivers. On the social front, we're committed to training and hiring locals, supporting local suppliers, and fostering entrepreneurship — all alongside our environmental standards and structured stakeholder dialogue. For instance, on top of direct and constant dialog with local community representatives, we've established permanent roundtables and Casa Era Dorada, located in the municipality of Asunción Mita, an open community space for sharing project information and addressing concerns. As we proceed, our commitment remains: to develop Era Dorada responsibly, listen actively, and demonstrate that modern mining can drive shared progress, environmental care, and mutual trust. I'm proud to say that we believe Era Dorada will set a global benchmark in social and environmental responsibility, just like Borborema and our other operating mines”
