The illustration below presents, in an integrated way, the main routes for mineral extraction, production, and processing used by Aura. The activities effectively applied at each unit are detailed in the Our Operations chapter.

Click the diagram stages to see the details.
Operation with haul trucks, drill rigs, and hydraulic excavators for efficient ore extraction.
Waste rock disposal in the underground mine takes place within the structure itself, used mainly for containment and geotechnical stability. Ore is extracted through mechanized drilling and then transported by haul trucks to the subsequent stages of the production process.
Size reduction of run-of-mine ore, preparing it for the next stages of processing.
Comminution of the ore with water added, producing the slurry that goes to the concentration stages.
Selective separation of minerals via reagents (hydrated lime, xanthate, aerophine, frother), producing copper, gold, and molybdenum concentrate.
Hydrometallurgy stage that uses LPG, cyanide, and caustic soda to extract gold from the loaded activated carbon.
Electrochemical recovery of gold with fluxes, producing doré bars.
Detoxification treatment with copper sulfate and sodium metabisulfite to neutralize residual reagents before final disposal.
Thickening and dewatering of tailings, reducing volume and optimizing disposal in piles or dams.
Geotechnical structures continuously monitored, aligned with international standards for safety and risk management.
At Minosa, waste rock pile management incorporates practices aimed at maximizing resource use and reducing environmental liabilities. In this context, the company carries out re-leaching of waste rock to recover remaining metals not previously extracted.
The water used in this process comes, in part, from the return of the thickening stage or the tailings dam, as applicable, ensuring its recirculation and promoting greater efficiency in water use.
More than a set of guidelines, it is our management model and the way we turn purpose into results
The Aura 360 Culture also supports and translates our sustainability strategy by integrating environmental, social, and governance (ESG) aspects, ensuring that value creation is always aligned with strategy across every business decision.

Era Dorada — rebuilding trust
The Era Dorada Project is located in a region sensitive to mining activity, marked by negative perceptions and environmental concerns. When Aura acquired the project, it inherited a scenario of low community trust — calling for an approach focused on rebuilding the project's legitimacy and advancing the social license to operate.
The strategy prioritized strengthening dialogue and active listening: clear communication about the project, decisions grounded in local perceptions (prioritizing underground mining, local employment and supplier policies), and a narrative built on cultural proximity, social and environmental responsibility, and shared value creation.
Formal, verifiable spaces for dialogue, prioritization, and participatory decision-making on social investment.
More than 1,000 hours dedicated exclusively to community relations across 2025.
Independent third-party audits of the social and environmental areas, evidencing changes in the management model.
A permanent center for information, public service, and community capacity-building.

“Building trust with communities is not just part of our work: it is the foundation for mining to generate real, lasting, and shared value for the territory.”
From mining, new harvests
Launched by the San Andrés Foundation — the social arm of the Honduras unit — the Semillas de Esperanza Project supports sustainable social and economic development by cultivating three grape varieties and the future production of wines, advancing a strategy of productive diversification.



“This is the first step of a major change we are building for the Minosa region and for Honduras. We are committed to creating a more prosperous future for everyone, acting with respect and care for the community and the environment to leave our positive legacy.”


Recognition: Mining Sector Company of the Year 2025 — ESG category (mid-cap).
Innovation that becomes sanitation
The start-up of the Borborema unit was not only a major step in our expansion plan — it also gave concrete shape to our commitment to producing in a sustainable way.
The unit sits at the heart of the Seridó region in Rio Grande do Norte, in Currais Novos, an area marked by severe water stress. It was in this context that we brought innovation and a sustainability commitment together, opening a mine that operates without consuming new water and does not affect the local community's water supply.
Through a public-private partnership with the Rio Grande do Norte Water and Sewer Company (CAERN), we now collect the city's domestic sewage, treating it fully and reusing it in the mine's activities. No groundwater, river, or stream water is used. The operation is fully supplied by urban sewage subjected to advanced treatment that includes reverse osmosis and multiple purification stages.
Today, the plant is fully operated by our team, transporting roughly 70 cubic meters of reuse water per hour through 27 kilometers of pipeline to the processing plant. The initiative earned Aura the recognition of Mining Sector Company of the Year 2025 in the ESG — Mid-Cap category.
In gold mining, greenhouse gases (GHGs) are generated mainly by fossil fuel combustion in equipment and transport machinery and by power generation for processing. Aura has put in place a range of strategies, both operational and long term.

GHG monitoring and inventory
Aura performs regular emissions inventories at its units as part of a comprehensive environmental risk management approach. This practice ensures local and global compliance and enables effective control of emissions.
Transport solutions
Optimization of haul routes with reduced average distances and fleet renewal with more modern, efficient equipment. At Apoena, replacing smaller trucks with larger models reduces diesel consumption per ton hauled.
Efficient technologies and processes
Investment in low-carbon technologies, including renewable energy and water efficiency. Borborema uses 100% reuse water from sewage treatment and rainwater.
Tailings reuse & circular economy
Practices like using tailings in concrete construction and remineralizing soils with rock dust reduce disposal needs and environmental impact, supporting natural-resource conservation.
Renewable energy
Periodic reviews of supply conditions, including analysis of opportunities to contract renewable energy whenever technically feasible, balancing operational efficiency and environmental performance.
Zero tolerance for non-compliance
In 2025, Aura kept its zero-tolerance stance toward non-compliance with laws and regulations and reinforced its Integrity Program, which is structured by corporate policies and internal regulations and anchored by the Code of Conduct as the main reference document for ethical guidelines.
The integrity system comprises Human Rights, Anti-Bribery and Anti-Corruption, Donations and Sponsorships, and Investigation policies, all approved by the Board and aligned with international references — including the Universal Declaration of Human Rights, the UN Guiding Principles on Business and Human Rights, and the World Gold Council principles (RGMP and conflict-free gold standard).
The recent acquisitions of the Mineração Serra Grande (Brazil) and Era Dorada (Guatemala) units called for specific focus to ensure the integration of people and processes into the Aura Compliance Program. For 2026, projects are planned to identify and assess compliance risks specific to the locations where the new units operate.
