Reference information

Comments Two rock chip samples contain 0.1 g/t Au and 2.3–6.6 g/t Ag. Soil sampling reveals anomaly aureoles of Ba (0.03-0.09%), Cu (0.005–0.009%) and Mo (0.004–0.008%). Grade of 0.12–0.25% Cu, rare 0.005–0.2% WO3, 0.005–0.05% Mo, and up to 0.01% Sn. Consists of disseminated Cu minerals in intensively altered subvolcanic syenite porphyry intruding Permian siliceous volcanic rock. Silicifica and argillite alteration occur along a NW-trending fault zone.
Study area name Central Asian Orogenic Belt
