Lundin Mining Announces Year End 2007 Reserve and Resource Estimate
VANCOUVER, BRITISH COLUMBIA–(Marketwire - March 28, 2008) - Lundin Mining Corporation (TSX:LUN)(NYSE:LMC)(OMX:LUMI) (“Lundin Mining” or the “Company”) is pleased to announce its updated Mineral Reserve and Resource estimate as of December 31, 2007. The 2007 Reserve and Resource estimate that follows represents a significant increase over 2006 resulting from: exploration success in expanding reserves and replacing production; a reassessment of cut-off grades; the acquisition of Rio Narcea which added nickel to the Company’s portfolio.

Reserves associated with this project, as estimated by the operator Freeport-McMoRan, are 100 million tonnes grading 2.27 TCu% and 0.33 TCo%. These are prepared to SEC standards.
Phil Wright, President and CEO of the Company, commented, “It is very pleasing to see the success of the operations and exploration teams during 2007.
“Despite record production at Zinkgruvan and Neves-Corvo, both operations have managed to replace their ore reserves as a result of infill drilling.
“Significant value has also been generated by the exploration teams in defining new Resources and upgrading Inferred Resources to Indicated,” Mr. Wright said.
Highlights
Neves-Corvo, Portugal
- An increase of 207% in the zinc Proven and Probable Reserve tonnage.
- Infill drilling has successfully delineated an initial zinc Indicated Resource at Lombador South of 15.6 million tonnes grading 7.7% Zn and 1.9% Pb. A supporting NI 43-101 technical report will be filed on Sedar (www.sedar.com) and the Company’s website within 45 days.
- A feasibility study is in progress on the Lombador South Zone to optimize exploitation of Lombador by sinking a new shaft to mine the zone independently. This study is scheduled to be completed by year-end, 2008.
Zinkgruvan, Sweden
- Zinc Proven and Probable Reserve tonnage increase of 22%.
- Zinc Measured and Indicated tonnage increase of over 135%.
- The copper Indicated Resource tonnage increased by 11%. Definition drilling is now underway as planned to convert the Indicated Resource to Reserve. This project is on track and the Company estimates first copper production in 2010.
Aguablanca, Spain
- A portion of the underground nickel Measured and Indicated Resources have been converted to Proven and Probable Reserves. Underground Reserves and Resources will be updated during the second quarter 2008 incorporating drilling completed after June, 2007.
Exploration
- The Company carries out exploration to discover and delineate new mineral resources. Exploration expenses of US$35.3 million were incurred in 2007, comprising US$26.6 million in direct costs, US$10.1 million of previously capitalized exploration expenditures and offset by a US$1.4 million recovery relating to the value of shares received in connection with two farm-out option agreements signed by the company in 2007. Direct costs were spent on copper-zinc exploration in Portugal, zinc-lead exploration in Sweden, Ireland and Spain and nickel-copper exploration in Spain. Approximately 130,000 metres of drilling were completed in 2007 with the majority devoted to resource exploration drilling that resulted in the substantive year-over-year increases in the resources presented in the accompanying tables.
- An exploration budget of US$38.9 million has been approved by the board of directors for 2008. This budget will again fund a drill-intensive program with a total 156,200 metres of drilling planned for 2008, including 55,400 metres planned for Portugal with the remainder apportioned between Spain, Sweden and Ireland. Of this total, about two-thirds will be devoted to resource exploration at and near to our mine operations with the objective of further increasing our mineral resource base. The remainder of the 2008 budget will be focused on regional base metals exploration largely within the prospective mineral belts that host our mines, including the Iberian Pyrite Belt.
The following tables summarize the Mineral Reserve and Resource estimates for each of the Company’s mines as of December 31, 2007 with 2006 comparisons for those operations that were owned by Lundin Mining in 2006.

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 Annual Information Form 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 that are disclosed or incorporated by reference in this 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.
