Regional Copper Potential
Evening Star is located in United States, 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 (very high elevation, high relief, dry climate) shapes access, seasonality, and operating costs. Geologically, the area is dominated by Unconsolidated sediments, under thin lithosphere with moderately thick sedimentary cover in a Meso- and Cenozoic Extended Crust tectonic province—factors that inform both deposit style and development complexity.
Drill Intercepts
Reported results (Copper Equivalent) average very high grade, short, and very deep. The most recent intercepts are benchmarked against a global copper database.
