Lundin Mining Announces Amendment to Credit Agreement to Increase Facility to US$350 Million and Extend Term to 2015

December 20, 2012

TORONTO, ONTARIO–(Marketwire - Dec. 20, 2012) - Lundin Mining Corporation (TSX:LUN)(OMX:LUMI) (“Lundin Mining”) is pleased to announce that it has executed an amendment to its revolving credit agreement (the “Amended Credit Agreement”) that increases the amount of its revolving credit facility (the “Facility”) to US$350 million from US$300 million, reduces the costs of borrowing and extends the term of the Facility to December 2015.

Two new banks were added to the syndicate of lenders and one institution, which is no longer in the business of commercial lending, exited. The continuing banks, which are comprised of Scotiabank, the Sole Lead Arranger and Sole Bookrunner, ING Belgium NV/SA and Bank of Montreal, the Co-Syndication Agents, Export Development Canada, the Documentation Agent and Skandinaviska Enskilda Banken AB as lender, are joined by Bank of America Merrill Lynch and Royal Bank of Canada as lenders.

Ms. Marie Inkster, Senior Vice President and Chief Financial Officer, commented, “Under the terms of the amended Facility, the Company now has the option to raise funds through the issue of high yield notes or convertible debt. This provides the Company with the flexibility to access significant levels of debt financing under the current capital structure.

“We are thankful for the ongoing support of the continuing lenders and welcome our two new lenders,” Ms. Inkster said.

The revolving Facility will bear interest on US dollar denominated drawn funds at rates of LIBOR+2.5% to LIBOR+3.25%, depending upon the Company’s leverage ratio. The Company can also borrow in Canadian dollars or Euros at other varying rates.

No advances are currently outstanding under the Facility other than a letter of credit in the amount of US$12 million (SEK80 million).

The Company’s wholly-owned Portuguese subsidiary, Somincor, has also finalized a renewal of that company’s domestic Portuguese Commercial Paper program. The program allows for the issuance of short term notes up to an amount of EUR30 million. The program has been used effectively in the past to manage working capital requirements and provides additional financial flexibility for capital management of operations and new investments at the Neves-Corvo mine. The program is underwritten by Santander Bank and drawn funds will bear interest at Euribor +3.6%. No advances are currently outstanding.

Lundin Mining has approximately US$300 million of cash on hand.
