Porphyry/skarn Cu-(Ag-Au-Mo) open-pit mine located at altitude of about 4000 m asl.
Under development as at 20th May 2014.
Owned by MMG.

Several deposits are related to the terminal phases of the middle Eocene to early Oligocene Yauri-Andahuaylas batholith.
The three Las Bambas project deposits, Ferrobamba, Chalcobamba and Sulfobamba are distributed over an approximate east-west interval of 15 km, with Chalcobamba being 8 km NW of Ferrobamba, and Sulfobamba, 5 km west of Chalcobamba, with Las Chancas being between the last two.

The bulk of the Cu(-Au, -Mo) mineralisation at Las Bambas was introduced during prograde events, typically as chalcopyrite and, less commonly, bornite. The distal skarn mineralisation is richer in Pb and Zn, and also contains structurally and lithologically controlled, yellow-brown jasperoid developed in limestone beyond the skarn front.

Located some 72 km SW of Cuzco and around 530 km SE of Lima.
