Duobaoshan Cu-Mo deposit, Liuzhan, Nenjiang Co., Heihe Prefecture, Heilongjiang Province (Manchuria; Dongbei Region), China

Porphyry Cu-Mo-(Au-Ag) deposit, located in a transitional uplift between the Daxingan Range (Daxinganling) and the Songliao Basin. The ore minerals form disseminations, veinlets and breccia in granodiorite and Late Ordovician andesite porphyry and tuff of the Duobaoshan Formation. The granodiorite forms a composite batholith with a surface exposure of 8 km2.

Reserves are 3,276,600 tonnes Cu, 122,900 tonnes Mo, 1,417 tonnes Ag, 87 tonnes Au, 24 tonnes Re (grading at 917 g/t in molybdenum ore), and 1,247 kg of PGE.
