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