Capstone Copper

Operations

Capstone Copper has a portfolio of long-life copper operations in the Americas and a fully permitted development project in one of the world’s most prolific copper-producing districts. We are well positioned to create near-term growth as we make our operating mines more profitable, and execute on our strategy of transformational growth as we build the next generation of responsible copper mines.

Operations

Through a commitment to innovation, excellence and operating at the highest standards, we are focused on generating strong cash flows in all price environments at our multi-asset portfolio of mines and projects.

Pinto Valley

Arizona, United States

100%-owned, operating open-pit copper-molybdenum mine located in the prolific Globe-Miami mining district of Arizona, one of the oldest and most productive mining districts in the USA. District consolidation opportunities are being explored to leverage synergies and create economies of scale.

Cozamin

Zacatecas, Mexico

100%-owned, operating underground copper-silver-zinc-lead mine. Since the first full year of operation in 2007, Cozamin has generated positive free cash flow at all points of the copper price cycle. Exploration program underway to evaluate opportunities for mine life extension.

Mantos Blancos

Antofagasta, Chile

100%-owned, operating open-pit, high-grade copper-silver mine. The operation currently mines and processes sulphide and oxide ores.

Capstone is currently evaluating the potential to increase throughput of the Mantos Blancos sulphide concentrator plant. Significant near mine and district exploration potential.

Mantoverde

Atacama, Chile

70% ownership (30% Mitsubishi Materials Corporation). Operating open-pit, oxide heap leach copper mine with 32,000 tpd high-grade sulphide processing line expansion (Mantoverde Development Project – “MVDP”) ramped up in 2024. Potential to expand throughput to 45,000 tpd through the Mantoverde Optimized Project (MV-O).

Near-mine exploration potential and district consolidation opportunities exist and continue to be pursued.

Santo Domingo

Atacama, Chile

Top-quartile, fully permitted copper-iron-gold project with cobalt opportunity, located in close proximity to the Mantoverde mine in Chile. Santo Domingo represents the next phase of transformational growth for the Company, with annual copper production averaging 106 thousand tonnes of copper for the first seven years of the mine plan. The project is currently preparing for sanctioning, with detailed engineering and financing decisions advancing.

MVDP

The Mantoverde Development Project (“MVDP”) represents a transformational expansion of our Mantoverde mine in Chile to process sulphide ore via a copper concentrator, in addition to the mine’s oxide ore processing capabilities. The $870 million project produced first copper concentrate in June 2024, achieved commercial production levels in September 2024, and ramped up to full milling rates by the end of 2024. The MVDP is expected to drive significantly higher consolidated production at lower unit costs for Capstone Copper.

Responsibility

We care deeply for our people, the environment, and the communities in which we operate. Our commitment to ethical and responsible mining is deeply rooted in our business philosophy, central to our values and vital to our success.
