HudBay Reports Progress in Lundin Acquisition

09:28 EST Thursday, December 11, 2008

TORONTO, ONTARIO--(Marketwire - Dec. 11, 2008) - HudBay Minerals Inc. (TSX:HBM) ("HudBay") continues to take steps to advance its acquisition of Lundin Mining Corporation (TSX:LUN)(NYSE:LMC)(OMX:LUMI) ("Lundin").

TSX CONDITIONAL APPROVAL

HudBay received conditional approval on December 10, 2008 from the Toronto Stock Exchange (the "TSX") with respect to the HudBay shares that will be issued as consideration in connection with the acquisition of the Lundin shares. Final approval of the listing of HudBay shares is subject to the ordinary conditions of the TSX for transactions of this nature and does not require the approval of the shareholders of HudBay.

ADDITIONAL STOCK EXCHANGE LISTINGS AND PROGRESS ON PRIVATE PLACEMENT

Consistent with its positioning as a new Canadian leader in global mining, HudBay has decided to pursue a listing on a U.S. stock exchange, and is considering listing on the OMX in Stockholm. Although HudBay and its shareholders continue to be well-served by the company's TSX listing, the company believes additional listings will enhance liquidity as HudBay grows and better meet the needs of its international investors. HudBay expects to complete a listing on a U.S. exchange in conjunction with the closing of the Lundin transaction.

Because HudBay has elected to pursue a U.S. listing, the previously announced private placement may now be completed in accordance with applicable U.S. federal securities laws. As a result, the company intends to close the private placement in accordance with HudBay's obligations under its subscription agreement with Lundin, and acquire 96,997,492 common shares of Lundin at a price of Cdn. $1.40 per share, representing a 19.9% interest in Lundin. Accordingly, the previously contemplated loan transaction with Lundin is no longer necessary.

RESPONSE TO REQUISITIONS FOR SHAREHOLDER MEETING

After carefully considering the requisitions of Jaguar Financial Corp. and another party requesting a shareholder meeting and after receiving the advice of legal counsel, HudBay's board of directors has determined that the requisitions are not valid as they do not satisfy the requirements of Section 143(1) of the Canada Business Corporations Act since their signatories were not registered holders of any shares of HudBay at the time of the request. HudBay's board of directors confirms that it will call a meeting of shareholders in accordance with the provisions of the Canada Business Corporations Act upon receipt of a valid requisition.

HudBay remains committed to completing the acquisition, which will provide the company's shareholders with outstanding producing assets in stable jurisdictions and excellent development opportunities while preserving superior balance sheet strength and providing strong cash flow.

HudBay encourages shareholders to refer to the websites of HudBay (www.hudbayminerals.com) and Lundin (www.lundinmining.com) for accurate, factual information about their respective operations and the proposed acquisition of Lundin.
