Ero Copper completes Phase 1 drill program at Furnas Copper-Gold Project, Brazil

Ero Copper (ERO) completed its Phase 1 drill program at the Furnas Copper-Gold Project, located in the Carajas Mineral Province in Para State, Brazil. Initial results from the completed 28,000-meter Phase 1 program are highlighted by significant down-dip intercepts, including: 105 meters at 1.17% copper and 0.77 gpt gold, including 63 meters at 1.30% copper and 1.13 gpt gold, drilled in the Southeast zone at the limit of the previously defined indicated resource; and 75 meters at 1.02% copper and 0.59 gpt gold, including 30 meters at 1.71% copper and 1.05 gpt gold and 15 meters at 2.30% copper and 1.60 gpt gold, also in the Southeast zone. Results continue to both demonstrate continuity and extend the known limits of mineralization within the high-grade mineralized zones that are the focus of future underground mining operations. Only one of 66 holes drilled by the Company during the Phase 1 campaign did not intercept mineralization. There are currently eight drill rigs operating on the Project, where the Phase 2 drill program is underway. The preliminary economic assessment initiated earlier this year, remains on track for completion during the first half of 2026.
