The Tanjianshan gold deposit is located about 250 km northeast of the city of Golmud, in Qinghai Provice of western China, between the Qaidarn basin to the southwest and Qilianshan Mountains to the northeast.

The district geology comprises Ordovician metasedimentary and metavolcanic rocks in an area of the high relief and the severe weather conditions. Gold ore occurs in both quartz veins and as disseminations in wall rocks.

Gold mineralisation is hosted in mylonitised, carbonaceous schists and phyllites. The orebodies, controlled by both NW and NE striking ductile-brittle structures and are exposed over an area of about 300 x 30 m, and continue to a depth of more than 200 m. Gold is associated with pyrite and arsenopyrite, with minor pyrrhotite, chalcopyrite, galena, and tennantite.

Tanjianshan is surrounded by numerous prospects, and contains 20 t Au at grades of 4 to 5 g/t Au.
