Minera Tres Valles is a mining project located near the towns of Salamanca and Illapel that is dedicated to the production of high grade copper cathodes.
Its efforts focus on exploiting its own ore bodies, Papomono (an underground deposit) and Don Gabriel (an open-pit mine), which were re-opened in October 2015.
Minera Tres Valles produces Electrolytic Copper Cathodes (Grade A) of 99.9999% purity through the mining of its own deposits and the purchasing of third party ore.
The small producers of the region form both an important part of our business and also of the communities where we are located.
Our processing plant operates under SX-EW (solvent extraction and electrowinning) technology in order to produce high grade copper cathodes. We are constantly seeking to innovate and optimize our processes in ways like improving the metallurgical rate of recovery, among others.
Minera Tres Valles has the power to purchase ore from third parties at its processing plant located near Salamanca.
This business model is characterized by being transparent and dynamic, seeking to support local miners in the management of their projects.
The Tres Valles Foundation is the institution by which Minera Tres Valles channels its social investment into the territory.
