Our Operation

Rosario and Ujina Deposits

Our operation consists in the open-pit exploitation of the Rosario and Ujina deposits and, to a lesser extent, the Huinquintipa deposit, all located at an average 4,400 metres above sea level in the Pica municipal district of northern Chile’s Tarapacá Region.

Copper concentrate is transported as slurry through a system of two pipelines, with a diameter of 7 and 8 inches, respectively, and a length of 203 kilometres, to the Collahuasi Port Terminal in the Patache sector, 65 kilometres south of Iquique.

In order to protect the environment, the operation seeks to ensure sustainable management of water resources and care of biodiversity and the environment in general.
