About Cerro Negro

The Cerro Negro mine is located 37km south east of the town of Cabildo in the Province of Petorca, V Region of Chile, and approximately 210km north of Santiago. All plant and mine sites are easily accessible and are located at elevations of less than 1200m in moderate terrain. Agricultural activity in the immediate area of the property is negligible and confined to rough grazing, apart from company sponsored trial avocado production.

Operations commenced in 1944, and between 1983 and 1996, Cerro Negro was owned by a predecessor company to Antofagasta Minerals, operating exclusively as a 1,200 tpd concentrator, producing 5,000 tpy copper in concentrates. In 1997, at a time of low copper prices and high costs, CMN was sold to its employees, and a small copper precipitate plant subsequently installed. This leaching operation was converted to SX in 1999 to produce copper sulphate and in 2001-02 to a 3,000 tpy SXEW operation; it was further expanded in 2005 to 4,000 tpy capacity and in 2007 to its current 6,000 tpy Cu.

Current copper cathode production capacity, including toll treatment, is approximately 6,000 tonnes per year, concentrator production capacity is approximately 9,600 tonnes of copper-silver concentrates per year, and copper sulphate production capacity is approximately 4,200 tonnes per year.

The toll treatment of oxides is governed by an agreement with Enami which purchases third party ore trucked in from small artisanal mines in the surrounding district. The agreement extends to 2011 and Cerro Negro production plan assumes treatment of 180,000 tonnes per year of this material to recover approximately 2,000 tonnes per year cathode.
