VANCOUVER, BRITISH COLUMBIA–(CCNMatthews - Dec. 8, 2006) - Lundin Mining Corporation (“Lundin Mining” or the “Company”) (TSX:LUN)(AMEX:LMC)(SSE:LUMI) has been informed by Union Resources Limited (“Union”) that Union has received a letter from its Iranian Government partner, Iranian Mines and Mining Industries Development and Renovation Organization (“IMIDRO”), purporting to terminate certain agreements relating to the Mehdiabad zinc project. The agreements include:

1. Formation Agreement dated October 30, 1999

2. Basic Agreement dated November 22, 1999

3. Management Agreement dated January 17, 2001

4. Engineering Services Agreement dated January 17, 2001

The full text of Union’s press release can be found at www.unionresources.com.au and includes the following statement by Union:

“Union is of the opinion that IMIDRO has invalidly issued the purported notice of termination and the board of Union is taking urgent steps to clarify and resolve the situation and ascertain the impact of the letter on Union’s investment in the Project.

Union is further of the opinion that the Company has complied with all of its obligations under the Foundation Agreement, the Basic Agreement and the Management Agreement, and that no basis exists for termination. Whilst Union is a signatory to the Engineering Services Agreement, it relates to work carried out on the Project by the other partner to the Joint Venture, Itok GmbH.”

In August 2005 Lundin Mining acquired a 19.9% interest in Union, a publicly traded Australian mining company, for a total consideration of approximately US$ 4.4 million. Union’s main asset is a 38% ownership in the zinc-lead deposit Mehdiabad in Iran. The Iranian State owns 50% of the Mehdiabad project and Itok the balancing 12%. Lundin Mining will continue to monitor the development in the Mehdiabad project. Although the deposit is of size, Lundin Mining holds a relatively small, indirect, interest in the project and does not consider that the possible termination of the agreement between Union and IMIDRO to be material.
