CHILE – Total resources at the Collahuasi copper mine in Region I have grown 28% and represent an additional 11.0 million tonnes of contained copper. The Collahuasi mine is a joint venture of XSTRATA COPPER (44%), ANGLO AMERICAN (44%) and a Japanese consortium led by MITSUI & CO.

The upgraded resource (at year-end 2007) of 5.19 billion tonnes at an average grade of 0.83% Cu includes for the first time 746 million tonnes at a grade of 1.06% Cu from the Rosario Oeste deposit. This compares with the previous resource of 4.05 billion tonnes at an average grade of 0.80% Cu estimated at the end of 2006. The mineral resource includes reserves of 2.20 billion tonnes at a grade of 0.82% Cu, a 25% increase in tonnage from a year earlier.

The partners have plans to more than double copper output to 1.0 million t/y. Collahuasi currently produces 400,000 tonnes of copper in concentrate, 60,000 tonnes of copper cathode and 3,360 tonnes of molybdenum annually. There are both a concentrator and an SX/EW plant at the site.
