The Antucoya copper project aims at producing an average of 80,000t/y of copper cathodes from an open pit and heap leaching-SX-EW facilities. It will require 7,000 workers during the construction phase and then generate 1,400 jobs during the ensuing operational phase. Antucoya will use salt water in all its processes.
Antucoya is operated by Antofagasta Minerals, a Chilean-based copper mining group traded on the London Stock Exchange. The deposit is a large but low grade resource, with 1.5Bt of mineral resource at an average copper grade of 0.27% at a cut-off grade of 0.10%.
In December 2012, the company temporarily suspended the development of the project while management completed a review of the project's costs and the potential for increases. In March 2013 Antofagasta Minerals decided to restart the project increasing capital costs to US$1.9bn.
