Atico Mining Expands El Roble Ore Body with High-Grade Copper-Gold Intercepts
Event summary
- Atico Mining reported high-grade copper and gold intercepts up to 10.20m of 6.26% Cu and 8.50 g/t Au at its El Roble mine in Colombia.
- 21 drill holes completed in 2025 expanded the ore body beyond historical mining areas.
- The deposit remains open at depth and along strike, with further drilling planned for 2026.
- El Roble's reserves estimate includes 828,000 tonnes averaging 2.49% Cu and 2.20 g/t Au, with a life of mine until Q1 2027.
The big picture
Atico Mining's successful drilling campaign at El Roble highlights the potential for significant resource expansion in an existing high-grade copper-gold mine. This aligns with broader industry trends of extending the life of mature assets through targeted exploration. The strategic anomaly here is the unexpected high-grade intercepts beyond the historical ore body, which could reposition El Roble as a longer-term producer in Colombia's mining sector.
