Corema, north Chile’s region I environmental regulator, has given EIA approval to Minera Doña Inés de Collahuasi for a $750m copper mine expansion that will raise mineral processing capacity at the mine by 20%.
The expansion, which is a key part of the company’s development strategy in the long run, will increase daily mineral processing capacity from 140,000t to 170,000t.
A company spokesperson told Bnamericas that the expansion will raise total annual output to 600,000t.
The project will generate employment for 2,500 people during construction and 300 once the project is finished.
Anglo American and Xstrata each have a 44% stake in the mine, while a Japanese consortium led by Mitsui & Co holds 12% stake.
