KAZAKHMYS PLC

Kazakhmys reported 6% less ore extracted at the Zhezkazgan complex in Q1 2009, with output of 5,908 kt, compared to 6,252 kt in Q4 2008. This reduction was in line with the production plan established at the start of the year. The main reduction was at West mine, where some operations were suspended due to their high operating cost. South and East mines have benefited with the transfer of some operations from West mine. The complex also benefited from increased output at the Stepnoy mine following the commissioning of a conveyer, which significantly improved the transportation of ore. Output was 2% higher than Q1 2008 as the reduction in output at West mine was offset by higher output at South and Stepnoy mines. The grade improved slightly in Q1 2009, compared to the previous periods, mainly due to higher grades at Zhomart. The production of copper in concentrate at the complex generally reflects the changes in ore output and grade. Cathode production from own concentrate at Zhezkazgan decreased in Q1 2009 by 35% compared to Q4 2008. This reduction was due to the planned maintenance being carried out at one of the two smelter furnaces, which is likely to remain non operational until ore volumes are returned to previous levels.
