Low sulphidation epithermal gold-silver deposit, located in the western part of the East Tianshan. The region is mainly underlain by Permian andesitic-dacitic rocks and volcanic breccia and their subvolcanic equivalents. There possibly was also a Permian volcanic caldera in the vicinity; amygdaloidal andesite and medium- to fine-grained tonalite recognized near the deposit have Rb-Sr whole rock isochron ages of 285±12 Ma and 293±1 Ma, respectively. Eighteen ore-bearing veins have been identified in the mine. The orebodies are arranged along a nearly WNW-trending set of tensile faults and form a swarm of auriferous quartz veins, that are up to 25 m thick, up to 200 m long, and extend 100 m downdip. The distribution of the orebodies is considered to be controlled by the intersection of the fracture system of the caldera with regional faults. Unlike many epithermal gold deposits, including the Axi gold deposit in the West Tianshan, the Shiyingtan gold deposit shows relatively weak wallrock alteration, which is silicification, sericitization, chloritization, and carbonatization.
