Kazakhmys PLC Update On Hong Kong Listing

Kazakhmys PLC ("Kazakhmys" or the "Company") announces that further to the announcement on 14 February 2011, the Company today announces its intention to pursue a secondary listing of its ordinary shares on the Hong Kong Stock Exchange.

Kazakhmys considers that this secondary listing will provide the Company with an additional channel to raise capital in the future and gain access to a wider range of institutional and retail investors. The listing will enhance the Company's profile in China and in Asia generally and thereby benefit the Company's long-term growth and development.

Subject to prevailing market conditions, the listing may be accompanied by an issue of new shares to assist liquidity on the Hong Kong Stock Exchange.

The Company has now filed a prospectus with the Hong Kong Stock Exchange and expects to complete the listing by the end of June 2011.
