Ero Copper Extends Furnas SE Zone 115m with 90m at 0.74% Cu
ERO•Ero Copper’s Furnas drill program intercepted 90m at 0.74% Cu, 0.50 g/t Au (1.13% CuEq) plus 32m at 1.17% Cu (1.70% CuEq), extending the SE zone by 115m down-dip. Ten rigs drilled 75,000m, targeting 6,000m of inferred resource conversion for a 60% stake by year-end before a 2027 Pre-Feasibility Study.
1. High-Grade Step-Out Intercepts
Ero reported significant step-out results at Furnas, including 90 meters at 0.74% copper, 0.50 g/t gold (1.13% CuEq) plus 32 meters at 1.17% copper (1.70% CuEq) in the SE zone, extending mineralization by 115 meters down-dip, and 45 meters at 0.98% copper (1.25% CuEq) beyond the inferred resource.
2. Expanded Drilling and Earn-In Progress
The company has completed over 75,000 meters of drilling through May 2026, including 24,000 meters in the ongoing program, with ten rigs focused on infill and step-out holes; Ero is on track to earn a 60% interest by year-end, roughly two years ahead of its earn-in schedule.
3. Path to Pre-Feasibility Study
Parallel workstreams support a Pre-Feasibility Study in 2027, with Ero advancing permitting, metallurgical testwork, geotechnical and hydrogeological studies and planning to award engineering contracts mid-2026, while evaluating magnetite recovery and gravity circuits to enhance project value.
