Regional Copper Potential
Liberdade is located in Brazil, South America. The surrounding region has historically demonstrated a moderate potential for copper endowment and is moderately proximal to other copper properties. Physical setting (moderate elevation, low relief, tropical climate) shapes access, seasonality, and operating costs. Geologically, the area is dominated by Precambrian rocks, under moderately thick lithosphere with moderately thick sedimentary cover in a Early Proterozoic Shield tectonic province—factors that inform both deposit style and development complexity.
Drill Intercepts
Reported results (Copper Equivalent) average very high grade, very long, and moderate depth. The most recent intercepts are benchmarked against a global copper database.
