Anglo American (LON: AAL) secured on Wednesday a supply agreement to meet almost half the water requirements of its Los Bronces copper mine in Chile with desalinated water from 2025.

The deal with Aguas Pacifico will allow the miner to bring ocean water to Los Bronces’ recirculation systems, with the goal of not drawing fresh water from the area where the mine is located.

In this first phase, the company will use 500 litres per second of desalinated water to cover 45% of its operations. In the second phase, Anglo plans to use treated wastewater in exchange for supplying desalinated water for human consumption.
