A High-Grade Copper Powerhouse in Chile

Chile is a global mining powerhouse, and the Coquimbo region is among its top producers of copper. The region offers vast, high-grade mineral reserves, stable and supportive mining regulations, and well-developed infrastructure. Its unique geology and investor-friendly climate make Chile a prime destination for efficient, large-scale copper extraction essential to the global energy transition.

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 from the surrounding communities, 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.
