Regional Gold Potential
Yamagano is located in Japan, Asia. The surrounding region has historically demonstrated a high potential for gold endowment and is somewhat distal to other gold properties. Physical setting (low elevation, moderate relief, temperate climate) shapes access, seasonality, and operating costs. Geologically, the area is dominated by Basic volcanic rocks, under very thin 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 (Gold Equivalent) average high grade, long, and very deep. The most recent intercepts are benchmarked against a global gold database.
