    The Wushan copper polymetallic deposit is located in the TongbaiDabie orogenic belt in central China. Two small granitoid stocks (Donggushan and Xigushan) occur in the deposit, which is next to the largest Qijianfeng Granite Complex in the Suizao area. The mineralization of Wushan copper polymetallic deposit is mainly composed of orebearing quartz veins and quartz stockworks.
