Chile's State copper firm outlines lifeline plan for Salvador mine

Chile's State copper miner, Codelco, has submitted an environmental impact assessment of its plans to overhaul its aging Salvador deposit that would sharply increase its production and extend its life by 40 years.

The Rajo Inca project would convert the existing mine, which has been in operation since 1959 and is due to run dry in its current state in 2021, to an opencast mine from an underground one.
