多宝山铜钼矿, 嫩江县, 黑河市, 黑龙江省, 中国

Porphyry copper-molybdenum-(gold-silver) 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 estimated at 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.
