Mantoverde Mine

Anglo American provided a further update on the situation in Chile. Affected copper mining operations - Los Bronces, El Soldado and Mantoverde - were able to resume full and safe production during Sunday when power was returned to all operations. It is expected that the Chagres smelter will resume full production by Wednesday following the resumption of full power supply. Lost copper production during the stoppage was limited to less than 1,500 tonnes. Minor damage was reported at Anglo American's copper mining operations.

Anglo American provided an update on its operations following the massive earthquake which struck Chile on Saturday. Due to the interruption of power supply, production was affected at four of the Company's copper operations in Chile - the Los Bronces, El Soldado and Mantoverde mines and the Chagres copper smelter. Power was partially restored to the operations during Saturday night and following detailed inspections production began to ramp up on Sunday. The affected mine operations produced 341,300 tonnes of copper in 2009, as part of Anglo American's total copper output of 669,800 tonnes for the year. Chagres smelter production in 2009 was 137,700 tonnes of anodes.

An investment of US$22.0 million was allotted for improvements in the leaching process focusing to incorporate technological improvements in equipments and operations of processing plant. In 1993, according to the EIS, the project was planned as an open pit for the extraction of 5.4 Mt/year of copper mineral, being the processing method by heap leaching and solvent extraction, and finally, 42,000 t/y of fine metallic copper grading 99.99% by electro obtaining. The project useful life was estimated in 16 years, during which 81.0 Mt of high grade mineral will be extracted and 21.0 Mt of low grade mineral, grading 0.82% Cu and 0.45% Cu respectively.
