Chile’s copper mining sector is undergoing a major transformation as it tackles severe water shortages that have long constrained production. At the heart of this shift is a strategic investment in advanced desalination infrastructure, which is set to redefine the future of mining in the arid Atacama Desert.
Anglo American’s Collahuasi mine, a joint venture with Glencore, is leading the charge. A new seawater desalination plant, currently under construction, is expected to reach full operational capacity by late 2026. Once online, it will provide a stable, climate-independent water source, enabling the mine to return to its target of 600,000 metric tons of annual copper output by 2027.
This move marks a critical departure from reliance on dwindling groundwater reserves, which have been strained by prolonged droughts and competing agricultural demands. The desalination project is structured in phases:
- 2024–2025: Initial construction with limited capacity
- Mid-2026: System integration begins
- Late 2026: Full operational capacity achieved
- 2027: Optimized performance and production recovery
By decoupling water supply from regional climate variability, the mining sector gains operational resilience and the ability to plan long-term production strategies with greater certainty.
Desalination is not just a stopgap—it’s a cornerstone of Chile’s broader strategy to maintain its global leadership in copper production. As global demand for copper surges—driven by electric vehicles, renewable energy, and digital infrastructure—ensuring water security through desalination is becoming a non-negotiable priority.
This infrastructure shift, combined with access to higher-grade ore and technological innovations in mining, positions Chile to meet rising global demand while aligning with sustainability goals.
