Ero Copper Corp. filed a NI 43-101 Technical Report and Preliminary Economic Assessment for its Furnas copper-gold project in Brazil, supporting earlier February 2026 disclosures. The study outlines an earn-in structure where Ero can acquire a 60% interest from Vale Base Metals by funding exploration, studies and future construction.
The PEA contemplates combined open-pit and underground mining over an initial 24-year mine life, with open pits delivering about 74.1 million tonnes of mill feed and an overall strip ratio of 3.2. Testwork supports average recoveries of 90.3% for copper, 74.6% for gold and 71% for silver, using a conventional flotation flowsheet to produce saleable concentrates.
Ero Copper Corp. filed a Form 6-K outlining three major agreements that reshape its Brazilian gold portfolio and partnerships. An additional precious metals purchase agreement with RGLD Gold AG expands the existing stream over NX Gold S.A.’s mining properties, becoming effective once specified conditions are met. Detailed tenement schedules list numerous Brazilian exploration permits, mining applications and one mining concession covering thousands of hectares, highlighting the scale of the NX Gold area.
A Third Amending Agreement to Ero Copper’s syndicated credit facility revises the definition of the NX Gold Mine to include twenty exploration licenses, a right to request a mining permit and two mining permit applications within a new “Stream AOI 2025,” and adds a corresponding map as a new schedule. The amendment confirms existing security remains in force and requires majority lender consent and an aligned change to the NX Gold stream intercreditor agreement.
An extensive Earn-in Agreement with Vale’s Salobo Metais S.A. gives Ero an exclusive option to earn a 60% ownership interest in the Furnas Property through phased exploration expenditures, technical studies (including Scoping Study, PFS and DFS) and a final investment decision process. Ero is operator during the earn-in, subject to a joint Technical Committee, environmental baseline work, ESG and anti-corruption standards, and Brazilian regulatory approvals, with detailed provisions for JV formation, put/call options and transfers if approvals are denied.
Ero Copper Corp. filed a Form 6-K featuring its 2025 Modern Slavery Act Report, outlining how it manages risks of forced labour, child labour, and related abuses across its Brazil-focused copper and gold operations and supply chain.
The company reports zero identified modern slavery incidents in 2025 and describes a zero-tolerance policy embedded in its Code of Business Conduct, Global Human Rights Policy, Supplier Code of Conduct, Health and Safety Policy, and Corporate Social Responsibility Policy. Governance rests with the executive committee, specialized legal, procurement and HR teams, with board-level oversight through the Environmental, Health, Safety and Sustainability Committee.
Ero highlights risk-based due diligence using third-party screening tools, supplier checks against Brazil’s “Dirty List,” and an Integrated Due Diligence Procedure to assess and, where necessary, mitigate or end relationships with higher-risk suppliers. In 2025 it introduced unannounced on-site inspections for certain suppliers and contractors, continued modern slavery training, and operated anonymous grievance hotlines in Brazil.
The report states that continuous improvement will continue in 2026, with plans to expand inspection coverage, strengthen data management and oversight, and further standardize due diligence and monitoring across operations and suppliers. The Board approved the report, and the CEO formally attested to its accuracy under Canada’s Fighting Against Forced Labour and Child Labour in Supply Chains Act.
