The Group operates four copper mines located in Chile, two of which also produce significant by-products.

Centinela, Antucoya and Zaldívar are all located in the Antofagasta region in the north of Chile, along with the now decommissioned mine at Michilla, while Los Pelambres is in the Coquimbo region.

The Los Pelambres and Centinela districts have long-life operations with significant mineral resources and produce significant by-products: gold, silver and molybdenum. Within these operations are five open pit mines and one underground mine.
