Report summary

The mine it is currently (2017) operating two open pits (Escondida and Escondida Norte) and since April 2017, after all water and power constraints were overcome, Escondida was expected to operate its three concentrators at a total capacity of 370kt/d ore. For 2018 it was expected a total milling capacity of 408kt/d ore (152kt/d ore for Laguna Seca and OGP1 respectively and 104kt/d ore for the Los Colorados). The total nominal capacity is 421kt/d ore. This provides Escondida with the capacity to offset the future declining quality of the ore. Additionally, Escondida operates two leach pads; a 48kt/d oxide ore pad and a 220kt/d ROM sulphide ore for leaching.
