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