Australian miner Metminco plans to use desalinated seawater at its Los Calatos copper-molybdenum project in southern Peru's Moquegua region, paper El Comercio reported.
Metminco is currently advancing a 50,000m drilling program at Los Calatos aimed at increasing the project's resource, which currently totals some 4.7Mt of copper equivalent.
The project could require an investment of US$2.2bn, according to the mines and energy ministry (MEM).
Water use is one of the more contentious issues facing miners in Peru today. In the country's arid coastal region, numerous projects have been delayed due to opposition from nearby communities concerned about the use of the resource.
The use of desalination plants is one of the solutions being proposed by miners.
