VANCOUVER, BRITISH COLUMBIA–(Marketwire - May 5, 2008) - Lundin Mining Corporation (“Lundin Mining” or the “Company”) (TSX:LUN)(NYSE:LMC)(OMX:LUMI) is pleased to announce the construction of an additional circuit within the existing copper plant at the Neves-Corvo mine in Portugal to recover copper and zinc currently lost to tailings.

Since the start of production at Neves-Corvo in 1988, important quantities of copper and zinc metal have been lost to tailings owing to the absence of a zinc circuit with the capability of treating locked copper/zinc bearing composite particles.

The new circuit will facilitate recovery of a proportion of the zinc and copper bearing minerals from the tailings stream as well as provide overall improved management of the mainstream concentrate.

Over the life of the mine this project is expected to produce 9,500 tonnes of payable copper, 29,000 tonnes of payable zinc and 370,000 ounces of payable silver.

The new circuit will comprise an Isa Mill, new flotation cells, a boiler and ancillary equipment. The estimated cost of the project is EUR 11.3 million (US$17.6 million) with EUR 8.0 million expected to be expended in 2008 and the balance in 2009. The project is anticipated to be operational in the second half of 2009.

This plant expansion is in addition to the previously announced Lombador zinc project currently undergoing detailed studies.

Mr. Phil Wright, President and CEO of Lundin Mining, commented, “This is a very robust project and is the result of the high quality work going on at all our operations seeking to maximize returns and enhance shareholder value.”
