Medium-scale granitoid-related vein-type gold deposit, hosted in chlorite amphibole schist, amphibole plagioclase gneiss and chlorite schist. Host minerals for gold are chalcopyrite and pyrite. Alteration is apparent and includes epidotization, chloritization, sericitization, pyritization and carbonatization. Gold mineralization is believed to be related to the shearing processes of the Archean Wulashan Group of metamorphic rocks.
