Las Bambas is a large, long-life copper mine located in Cotabambas, Apurimac region of Peru.

Las Bambas is a joint venture project between the operator MMG (62.5%), a wholly owned subsidiary of Guoxin International Investment Co. Ltd (22.5%) and CITIC Metal Co. Ltd (15.0%).

In December 2015 Las Bambas achieved a significant milestone with the production of first copper concentrate as part of commissioning activities for the mine.  First shipment of copper concentrate to customers departed the Port of Matarani in January 2016.

Las Bambas completed construction in the first quarter of 2016, and continues to progressively ramp-up with commercial production achieved on 1 July 2016.  Las Bambas is one of the world’s largest copper mines, with an annual nameplate throughput capacity of 51.1 million tonnes.

Las Bambas produced 453,749 tonnes of copper in copper concentrate during 2017, and is expected to produce between 375,000 to 395,000 tonnes of copper in copper concentrate in 2018. The operation will position Peru as one of the top copper producers in the world and become a strong contributor to social investment and local employment in the region.



Ore at Las Bambas is mined from an open pit. The ore is crushed and transported on a 5.5-kilometre overland conveyor to a conventional flotation plant where copper concentrate is produced, then to a molybdenum plant for further processing.
