Figures as of December 2010
Los Pelambres is a sulphide deposit located in Chile’s Coquimbo Region, 240 km north-east of Santiago. It produces copper concentrate (containing gold and silver) and molybdenum concentrate, through a milling and flotation process.
The plant expansion initiated in mid-2008 was successfully completed, on schedule and on budget, during the first quarter of 2010. The additional plant infrastructure, including a third SAG mill and a sixth ball mill, has increased throughput capacity to a 175,000 tonnes per day level.
The initial forecast for 2011 production is for approximately 419,000 tonnes of payable copper, a 9% increase compared with 2010. This is based on an average plant throughput of 175,000 tonnes per day, given a full year of operation of the plant at the expanded capacity. The initial forecast for 2011 molybdenum production is for approximately 9,300 tonnes, again based on the impact of the increased plant throughout.
