Sierra Gorda

Sierra Gorda Sociedad Contractual Minera (SGSCM), is a mining company that started its productive activity in 2014 and operates a deposit located in the Antofagasta Region, in the commune of Sierra Gorda; 60 km from the city of Calama, 150 km from the city of Antofagasta and 4.5 km from the town of Sierra Gorda. Located at an altitude of 1,626 meters, in the middle of the Atacama Desert, are its main mining and ore processing facilities such as: pits, tailings dumps, sulfide processing area (crushing, grinding, flotation and thickening) and thickened tailings deposit, among others.

The mining site consists of a “Porphyry Copper” type deposit, with copper, molybdenum, gold and silver mineralization on a smaller scale. The neighboring localities with which it interacts are Sierra Gorda, Baquedano and Mejillones.

Sierra Gorda is one of the main producers of copper and molybdenum concentrate in Chile and the world, producing concentrates with low grade copper sulfide ores, with the constant challenge of seeking alternatives for production efficiency and innovation, positioning itself as a pioneer in low grade mining.

They also work to maintain competitiveness and maximize their production, always aiming at continuous business improvement through a Zero Harm Culture and care for people, the environment and their communities. 

The plant has an approved capacity of 230,000 metric tons per day (TPD). Processing at the plant currently ranges from 110,000 (TPD) to 130,000 (TPD) of treated material.
