Northern Chile’s region I environmental regulator Corema approved an EIA for copper miner Minera Doña Inés de Collahuasi’s US$750mn expansion project, aimed at increasing ore processing capacity by 20% to 170,000t/d from the current 140,000t/d, the company said in a release.
London-listed Anglo American and Xstrata each own 44% of the mine; the remaining 12% is owned by a consortium of Japanese companies.
