Aura Announces its 2025 Sustainability Report

ROAD TOWN, British Virgin Islands, May 19, 2026 (GLOBE NEWSWIRE) -- Aura Minerals Inc. (NASDAQ: AUGO and B3: AURA33) (“Aura” or the “Company”) announces its 6th Annual Sustainability Report showcasing the Company’s progress in promoting safety, responsibility, sustainability, and innovation, prepared in with reference to Global Reporting Initiative (GRI) standards, the report ensures clear and transparent disclosure of Aura’s financial, environmental, and social performance. The full report can be found on “Sustainability - Aura Minerals” on Aura’s website.

Rodrigo Barbosa, President & CEO commented: “At Aura, we view mining not only as a responsibility to meet environmental and social expectations and regulations, but as a unique opportunity to go beyond compliance and actively create shared value for communities, the environment, and all stakeholders — especially in remote regions that often lack basic infrastructure. Concrete examples of this approach include turning wastewater from a neighboring city into process water for gold production in Brazil’s semi-arid region, and repurposing mining waste as agricultural inputs in Almas. In Honduras, through our Sementes da Esperança project, we are introducing innovative technology developed in Brazil to transform formerly mined areas into high-value crops, particularly grapes for the production of premium wines. In 2025 alone, we directed US$ 174.7 million to local suppliers — equivalent to 43% of our total purchases — while hiring approximately 67% of our workforce from the communities where we operate. We also achieved zero lost-time accidents across our operations and continue to expand initiatives in operational innovation, artificial intelligence, and the creation of a lasting legacy in the territories we touch.”

2025 Sustainability Report Highlights:

Water Reuse in the Semi-Arid Region One of Aura’s main environmental highlights is the Borborema operation, in Rio Grande do Norte. The company invested approximately R$ 45 million in the construction of a Wastewater Treatment Plant (WTP). Through a partnership with the Water and Sewage Company of Rio Grande do Norte (CAERN), the project captures domestic sewage from the municipality of Currais Novos, treats the water, and reuses it in the mining operation. The water travels more than 27 kilometers to the plant and is continuously reused throughout the operational process, reducing pressure on local water resources and contributing to urban sanitation in the region.
Post-Mining and Social Development: On the social agenda, one of the year’s main highlights was the progress of the Sementes da Esperança (Seeds of Hope) program, a project being developed by Aura through the San Andrés Foundation in the Copán region of Honduras, aimed at creating economic alternatives in post-mining regions. The initiative is transforming previously mined areas into vineyards, with the potential for future high quality wine production. Still in its early stages, this pilot project aims to connect land restoration, income generation, and local economic development, demonstrating how shared value can be created through the rehabilitation of impacted areas. Between 2024 and 2025, 1,440 grapevines were planted in reclaimed areas, with a survival rate of 84%. Inspired by economic diversification experiences observed in the interior of São Paulo, the initiative was structured based on the company’s own studies on local climate, soil fertility, and agricultural potential. It is expected that, after the testing and maturation phase, the activities will contribute to the creation of approximately 250 direct and indirect jobs in the region. Building long-term relationships with communities is also part of the company’s strategy in the territories where it operates. In Guatemala, Aura dedicated more than 1,000 hours to permanent community dialogue sessions — including weekly routines, site visits, and open forums to address questions. As a result, Aura modified the original project to not only address local concerns but to go beyond them. The company approved specific investments to treat water to drinking-water standards, making Era Dorada one of the first municipalities in Guatemala to have access to purified water.
Waste Repurposing and Operational Innovation: At the Almas unit (TO), Aura advanced the Soil Remineralizer Project, an initiative that transforms rock dust generated during mining operations — material that would otherwise be sent to tailings dams — into an agricultural input for soil remineralization. Agronomic and food safety tests have demonstrated promising potential for controlled application in agriculture. For the company, innovation is part of the business and is not limited to large projects — it is also present in the small improvements that transform day-to-day operations. In 2025, the company registered 623 ideas from its teams, a 30% increase compared to the previous year. Global efficiency initiatives generated savings of US$ 45.6 million for the company. At Aranzazu, in Mexico, the Company expanded the use of artificial intelligence and automation in mineral processing control. The Automet project, which integrated statistical data analysis, artificial intelligence algorithms, and advanced process control, reduced input costs by approximately 16% in six months, while also generating gains in copper, gold, and silver metallurgical recovery.
