Lundin Mining Announces Amendment to Credit Agreement to Increase
Facility to US$350 Million and Extend Term to 2015 
TORONTO, ONTARIO -- (Marketwire) -- 12/20/12 -- 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 cap
ital 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.
