Minera Tres Valles

About Minera Tres Valles

Minera Tres Valles (MTV) is a producing copper operation located in the Coquimbo Region of Chile, one of the world’s most stable and mining-friendly jurisdictions. The site combines open-pit and underground mining at Don Gabriel and Papomono, supported by a state-of-the-art SX-EW plant to produce Grade A (99.99%) copper cathodes.

In addition to its own ore, MTV processes material from local small-scale miners, contributing to regional development and employment. Over 60% of the workforce is locally sourced, and third-party mining is supported through formalized access agreements.

With strong commitments to sustainability, safety, and community engagement, MTV plays a key role in both GCR Group’s copper growth strategy and the economic vitality of the Choapa Province.

Together, we turn local expertise into shared progress, empowering people, growing economies, and ensuring that mining benefits everyone.

Advanced SX-EW Technology for High-Purity Copper

At Minera Tres Valles, we use advanced Solvent Extraction and Electrowinning (SX-EW) technology to produce high-purity copper cathodes (99.99%). This efficient, low-impact process recovers copper from oxide ores with precision and care to deliver world-class quality while minimizing environmental impact.
