Regional Copper Potential
Buen Retiro is located in Chile, South America. The surrounding region has historically demonstrated a very high potential for copper endowment and is very proximal to other copper properties. Physical setting (moderate elevation, very high relief, dry climate) shapes access, seasonality, and operating costs. Geologically, the area is dominated by Basic volcanic rocks, under very thick lithosphere with thin sedimentary cover in a Meso- and Cenozoic Orogen tectonic province—factors that inform both deposit style and development complexity.
Drill Intercepts
Reported results (Copper) average high grade, very long, and very deep. The most recent intercepts are benchmarked against a global copper database.
