Regional Gold Potential
Sierra Azul is located in Colombia, South America. The surrounding region has historically demonstrated a very low potential for gold endowment and is proximal to other gold properties. Physical setting (moderate elevation, high relief, tropical climate) shapes access, seasonality, and operating costs. Geologically, the area is dominated by Mixed sedimentary rocks, under very 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 Equivalent) average very high grade, long, and very deep. The most recent intercepts are benchmarked against a global gold database.
