Sustainability
Mining the metal of the energy transition, responsibly.
Copper is essential to a low-carbon world. We produce it with renewable power, careful water and tailings stewardship, and lasting benefit for the communities of Sonora and Atacama.

Our approach
Built into how we mine, not bolted on.
Sustainability sits at the centre of Altamira’s strategy. The same long-life, low-cost assets that make us competitive also let us invest in cleaner energy, safer operations and stronger communities for the decades our mines will run.
We report annually against recognised ESG frameworks and hold ourselves to clear, measurable targets.
