The
polymetallic mine is located at altitude of about 4000 meters above sea level in
Challhuahuacho District of
Cotabambas Province in the
Apurímac Region of the southern
Peruvian
Andes. Production is about 140,000 tons of
copper ore / day. The estimated mine life is at least 20 years. Las Bambas project also produces
molybdenum concentrates. Both metals are transported to Puerto Matarani, first overland to a transfer station in
Pillones followed by railways to
Matarani Port. Geoservice Ingeniería prepared the
Environmental Impact Assessment (EIA) for expansion of the Pillones transfer station. GyM S.A, the largest construction company in Peru and a subsidiary of the
Graña y Montero company, in 2012 was in charge of constructing the copper concentration plant with a capacity of 140,000 t/day. Production at the mine was scheduled to start in 2015 following an 80% confirmation completion of the project on 31 Dec 2014. The first production of concentrate out of the mine is expected to be in the first quarter of 2016. ==Conflict==
