VANCOUVER, BRITISH COLUMBIA–(Marketwire - Oct. 1, 2007) - Lundin Mining Corporation (TSX:LUN)(NYSE:LMC)(OMX:LUMI) (“Lundin Mining” or the “Company”) is pleased to announce that the Company has closed its agreement with Silverstone Resources Corp. (“Silverstone”) (TSX VENTURE:SST), announced on June 6, 2007, to deliver its silver production from the Neves-Corvo and Aljustrel mines to Silverstone. The agreement has been approved by regulatory authorities.

Under the agreement, Lundin Mining will receive an up front cash payment from Silverstone of US$42.5 million, together with 19,656,250 Silverstone common shares. The Silverstone common shares issued to Lundin Mining will be subject to a four-month hold period. Lundin Mining will also receive cash payments upon delivery of its silver production to Silverstone in an amount equal to the lesser of (a) US$3.90 per ounce of silver (subject to a 1% annual inflationary adjustment after three years and yearly thereafter) and (b) the then prevailing market price per ounce of silver.

The Neves-Corvo mine, located in southern Portugal, annually produces approximately 0.5 million ounces of silver contained in copper concentrate. The Aljustrel mine, which is scheduled to begin production in the fourth quarter 2007, is expected to produce approximately 1.2 million ounces of silver in lead concentrate, on an annual basis, by 2009 when it reaches capacity.

Joao Carrelo, Executive Vice President and COO of Lundin Mining, commented, “The closing of the agreement to sell our silver production to Silverstone, which is a by-product for Lundin Mining, will allow us to focus on and develop our core metals. The Company is currently investigating several opportunities to increase production through organic growth at both of our operations in Portugal. At Neves-Corvo, the life of mine business plan is being reviewed with the aim of optimizing the exploitation of its substantial copper and zinc resources by increasing future metal production at the mine. As the Aljustrel mine prepares to commence production in late 2007, management is considering alternatives that would significantly augment production by including additional resources into the mine plan.”
