Lundin Mining Announces Updated Mineral Reserves and Resources

 
VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 8, 2007) - Lundin Mining Corporation ("Lundin Mining" or the "Company") (TSX:LUN)(AMEX:LMC)(SSE:LUMI) is pleased to provide an update on the Company's estimated mineral reserves and resources as at December 31, 2006.

Mr. Karl-Axel Waplan, President of Lundin Mining, commented, "Work carried out in 2006, including resource definition and in-mine exploration drilling, was extremely successful in replacing production with new resources and extending the estimated mine life of several of the Company's mines including the Aljustrel project currently under development."

Highlights include:

Neves-Corvo

- Increased zinc measured and indicated resources by over 4 million tonnes.

- Increased copper measured and indicated resources by 750,000 tonnes at year end after allowance for 2 million tonnes of copper ore mined during the year.

Zinkgruvan

- Upgraded 1.3 million tonnes of high grade zinc ore to the proven and probable reserve category resulting in a net increase of 500,000 tonnes after allowance for the approximately 800,000 tonnes mined during the year.

Aljustrel

- Addition of the Estacao deposit increased zinc measured and indicated resources by 5.4 million tonnes for a total of 23.6 million tonnes. Inferred resources increased by 4.8 million tonnes to 9.3 million tonnes.

Following is a summary of reserves and resources as at December 31, 2006 for each of the Company's mines.

The 2006 and 2005 Galmoy Mineral Resource data is exclusive of the Mineral Reserve and is estimated at a cut off of 4.5% Zinc Equivalent (Zn + Pb/2). The 2006 and 2005 Mineral Reserve is estimated at a cut off of 6.0% Zinc Equivalent and a minimum mining height of 4.1 metres. No new reserves or resources were added during the year. Conversion from 2D to 3D block modeling reduced proven and probable reserves by 373,000 tonnes at year end, in addition to the 597,000 tonnes of ore mined during the year.

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 and zinc; that the companies can access financing, appropriate equipment and sufficient labour and that the political environment where the Companies operate 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.
