Large-scale epithermal vein deposit, located west of the NE-striking deep-seated Deerbugan fault zone. The deposit is controlled by the large NWW-trending Jiawula-Chaganbulagen fracture zone. The igneous intrusives are mainly late Yanshannian porphyries, consisting of quartz porphyry, feldspathic porphyry, monzonitic porphyry and granodioritic porphyry. Their whole rock K-Ar ages are 131.6-144.78 Ma. The ore-hosting rocks are mainly those of the late Permian Laorongtou formation: intermediate-basic volcanic rocks, sandy conglomerates, slate and rhyolite, etc. The ore-hosting fracture zone is more than 3000m long and 50-150m wide, with a strike of 280-290° and a SW dip of 40-60°. Five orebodies have been discovered. The main wallrock alterations are silicification, chloritization, epidotization, illitization, sericitization, carbonation etc.
