Middle scale gold-copper deposit, consisting of an upper gold-bearing breccia pipe and lower copper-bearing stockworks. The deposit is located in a caldera east of the Yishu deep fault, consisting of Early Cretaceous volcanic and subvolcanic rocks (shoshonites and high-K calc-alkaline rocks). The orebodies occur along the periphery of the pipe, and are composed of brecciated rock fragments cemented by specularite and minor amounts of pyrite and quartz.
