TORONTO, ONTARIO–(Marketwire - Feb. 22, 2010) - Lundin Mining Corporation (“Lundin” or the “Company”) (TSX:LUN)(OMX:LUMI) today reported its Mineral Reserve and Resource estimates as at December 31, 2009.
Investment in in-mine and near-mine exploration has seen the growth of mineral reserves to replace record ore tonnages mined during the year at both Neves-Corvo and Zinkgruvan. In addition, at Neves-Corvo there has been an increase of 11 million tonnes (+44%) in measured and indicated copper resources (approximately 160,000 tonnes of contained copper or roughly equivalent to 2 years of production) and over 20 million tonnes have been added in inferred copper resources.
At Tenke Fungurume (“Tenke”) in the Democratic Republic of Congo, exploration during 2009 has resulted in further increases in mineral resources. Three new deposits have been added to the mineral reserves in 2009 resulting in an increase in proven and probable reserves of 1.1 million tonnes of contained copper.
Commenting on the 2009 estimates, Mr. Phil Wright, President and CEO of Lundin Mining said, “Our goal this past year was to increase copper resources at Neves-Corvo and the increases we have seen continue to justify this on-going investment, and our belief that Neves-Corvo remains under-explored.”
“Equally pleasing is the growth of the mineral reserves at Tenke and the significant increase in the contained copper and cobalt in reserves,” Mr. Wright said.
The tables attached to this release summarize the Mineral Reserve and Resource estimates for each of the Company’s mines as of December 31, 2009. In addition, reserves and resources are reported for the Tenke Fungurume Project, in which Lundin Mining has a 24.75% equity interest.

Lundin Mining plans to update the Mineral Reserve and Resource estimates as at June 30, 2010, and annually thereafter. This aligns timing of updates with annual planning processes.

Forward Looking Statements
Certain of the statements made and information contained herein is “forward-looking information” within the meaning of the Ontario Securities Act or “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934 of the United States. Forward-looking statements are subject to a variety of risks and uncertainties which could cause actual events or results to differ from those reflected in the forward-looking statements, including, without limitation, risks and uncertainties relating to foreign currency fluctuations; risks inherent in mining including environmental hazards, industrial accidents, unusual or unexpected geological formations, ground control problems and flooding; risks associated with the estimation of mineral resources and reserves and the geology, grade and continuity of mineral deposits; the possibility that future exploration, development or mining results will not be consistent with the Company’s expectations; the potential for and effects of labour disputes or other unanticipated difficulties with or shortages of labour or interruptions in production; actual ore mined varying from estimates of grade, tonnage, dilution and metallurgical and other characteristics; the inherent uncertainty of production and cost estimates and the potential for unexpected costs and expenses, commodity price fluctuations; uncertain political and economic environments; changes in laws or policies, foreign taxation, delays or the inability to obtain necessary governmental permits; and other risks and uncertainties, including those described under Risk Factors Relating to the Company’s Business in the Company’s Annual Information Form and in each management discussion and analysis. Forward-looking information is in addition based on various assumptions including, without limitation, the expectations and beliefs of management, the assumed long term price of copper, lead and zinc; that the Company can access financing, appropriate equipment and sufficient labour and that the political environment where the Company operates will continue to support the development and operation of mining projects. Should one or more of these risks and uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described in forward-looking statements. Accordingly, readers are advised not to place undue reliance on forward-looking statements.
Cautionary Notes to Investors - Reserve and Resource Estimates
In accordance with applicable Canadian securities regulatory requirements, all mineral reserve and mineral resource estimates of the Company disclosed or incorporated by reference in this news release have been prepared in accordance with Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”), classified in accordance with Canadian Institute of Mining Metallurgy and Petroleum’s “CIM Standards on Mineral Resources and Reserves Definitions and Guidelines” (the “CIM Guidelines”). The definitions of mineral reserves and mineral resources are set out in our disclosure of our mineral reserve and mineral resource estimates in our Annual Information Form.
The Company uses the terms “mineral resources”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources”. While those terms are recognized by Canadian securities regulatory authorities, they are not recognized by the United States Securities and Exchange Commission the “SEC”) and the SEC does not permit U.S. companies to disclose resources in their filings with the SEC.
Pursuant to the CIM Guidelines, mineral resources have a higher degree of uncertainty than mineral reserves as to their existence as well as their economic and legal feasibility. Inferred mineral resources, when compared with measured or indicated mineral resources, have the least certainty as to their existence, and it cannot be assumed that all or any part of an inferred mineral resource will be upgraded to an indicated or measured mineral resource as a result of continued exploration. Pursuant to NI 43-101, inferred mineral resources may not form the basis of any economic analysis, including any feasibility study. Accordingly, readers are cautioned not to assume that all or any part of a mineral resource exists, will ever be converted into a mineral reserve, or is or will ever be economically or legally mineable or recovered.

Notes on Mineral Reserves and Resources Table
Mineral Reserves and Resources are shown on a 100 percent basis for each mine. Mineral Resources for all operations are inclusive of Reserves and all estimates are prepared as at December 31, 2009.
Estimates for all 100% owned operations are prepared by or under the supervision of a Qualified Person as defined in National Instrument 43-101. Tenke Proven and Probable Reserves are estimated by the operator Freeport-McMoRan Copper & Gold Inc. (“Freeport”), and are prepared to SEC standards and are reviewed by Lundin Mining’s independent Qualified Persons.
The Mineral Resources are reported above cut-off grades of 1.0% for copper and 3.0% for zinc and the Mineral Reserves at a cut-off of 1.6% for copper and 4.3% for zinc. Mineral Reserves and Resources for Neves-Corvo were estimated by the mine’s geology and engineering department under the guidance of Nelson Pacheco, Chief Geologist and Fernando Cartaxo, Mine Planning Engineer, and audited by consultants Wardell Armstrong International (WAI). Qualified Persons are WAI personnel Mark Owen, Principle Geologist and Owen Mihalop, Senior Mining Engineer.
