Project Details


The initiative, property of the chilean Las Cenizas, involves the ore exploitation at the Barreal Seco deposit, a open pit operation of oxidized copper ores. The main goal of the project is to provide a continous supply of mineral to the Taltal oxide plant, in order to reach an annual production of 12,000 tonnes of copper cathode. The project includes plans to construct a 36km road in order to truck high grade ore to the Taltal oxide plant, to obtain copper cathodes. In the first stage of the project, the project considers the construction of 12km of road, from the plant to the route B-965. The remaining 24km will be completed during he second stage, in the third year of operation. Low-grade ore will be leached in dump piles located in the project area.
