TORONTO, ONTARIO–(Marketwire - May 25, 2011) - Lundin Mining Corporation (“Lundin Mining” or the “Company”) (TSX:LUN)(OMX:LUMI) announced today that it has concluded its previously announced strategic process to explore alternatives for the creation of shareholder value. Although the Company received a number of non-binding expressions of interest with respect to both its assets and the Company, the Board of Directors, after careful consideration and following the receipt of advice from its financial advisors, has determined that these proposals did not adequately value the Company or its assets and that the best way to create shareholder value is to continue to manage and develop the Company’s quality assets and to actively seek growth opportunities.

In a related announcement, the Company stated that, in accordance with previously announced plans to retire during the first half of 2011, Mr. Phil Wright will be stepping down as CEO effective June 30, 2011 at which time Mr. Paul Conibear, currently the Senior Vice President, Corporate Development, will be appointed as Interim CEO. The Board has appointed a search committee to recruit a permanent CEO and an executive recruiting firm has been retained.

Lundin Mining also announced that the Shareholder Rights Plan adopted on March 29, 2011 will expire in accordance with its terms on May 31, 2011.
