Kazakhmys PLC Lists on the

Main Board of the Hong Kong Stock Exchange

Kazakhmys is pleased to announce the successful listing of its ordinary shares on the Main Board of the Stock Exchange of Hong Kong today.

No new shares have been issued or sold, but Kazakhmys may consider issuing some shares into the Hong Kong market at a later date, in order to assist liquidity. Any future issuance will depend upon share price levels and capital requirements, particularly as the major growth projects at Aktogay and Bozshakol progress.

Oleg Novachuk, Chief Executive Officer, said: "Our secondary listing in Hong Kong is important for the strategic development of Kazakhmys. Asia and China provide an increasingly significant customer and financing base for us. This listing will help raise our profile in the region's major financial centre and will support the future development of our business by providing access to a much wider group of investors."
