Lundin Mining to Acquire High Grade Eagle Nickel/Copper Mine

Lundin Mining to Acquire High Grade Eagle Nickel/Copper Mine 
TORONTO, ONTARIO -- (Marketwired) -- 06/12/13 -- Lundin Mining
Corporation (TSX:LUN)(OMX:LUMI) ("Lundin Mining" or the "Company") is
pleased to announce that it has entered into a definitive agreement
with Rio Tinto Nickel Company, a subsidiary of Rio Tinto plc ("Rio
Tinto") to purchase its 100% ownership stake in Rio Tinto Eagle Mine,
LLC, which owns the high grade Eagle nickel/copper underground mine
located in northern Michigan, U.S.A. The agreed purchase price is
approximately US$325 million, consisting of a US$250 million purchase
amount plus project expenditures from January 1, 2013 until
transaction closing of approximately $75 million, payable in cash,
and subject to customary adjustments.  
Paul Conibear, President and CEO commented, "The acquisition of the
Eagle Mine fits ideally within Lundin Mining's asset base and is the
result of the disciplined approach we have been focused on for some
time to acquire high quality, advanced stage assets in low risk,
mining oriented jurisdictions. The Eagle Mine represents a very
unique opportunity to acquire a high-grade project which is under
construction and expected to begin generating significant levels of
metal production and cash flow prior to the end of next year.
Northern Michigan has an outstanding iron ore, gold and base metals
mining history and consequently excellent regional power, road and
rail infrastructure, with extensive mining expertise within local
communities to support and staff Eagle Mine."  
The Eagle Mine is located in Marquette County in the Upper Peninsula
of Michigan. Project construction is slightly more than 50% complete
with initial production expected to commence in Q4 2014. Annual
production over the first three full years (2015 - 2017) is expected
to average approximately 23,000 tonnes of nickel and 20,000 tonnes of
copper per annum, with additional by-product credits of precious
metals and cobalt. Due to the high nickel grades and strong
by-product credits, C1 cash costs for the first three years are
expected to average approximately $2.00/lb nickel, thereby strongly
positioning the asset in the lowest quartile of the nickel producer
cost curve.  
Key Investment Highlights 

--  High grade nickel/copper deposit in a low-risk jurisdiction 
--  High quality nickel and copper concentrates with low technical and
    processing risk 
--  Project construction is just over 50% completed 
--  Production expected to commence Q4 2014 
--  Expected to be lowest quartile cost nickel producer 
--  Short payback period and strong cash flows 
--  Exploration upside with potential for increase in resources

Eagle Mine Overview 
The Eagle Mine is a high grade nickel/copper deposit with Probable
Ore Reserves estimated in accordance with JORC of 5.18 million tonnes
at 2.93% nickel and 2.49% copper anticipated to produce on average
approximately 17,000 tonnes per annum nickel and 17,000 tonnes per
annum copper, with gold, cobalt, platinum and palladium by-products
over the current life of mine of approximately 8 years. In close
proximity to the Eagle Mine deposit, several exploration targets have
been identified. Exploration efforts will be advanced in this highly
prospective area of interest to identify additional resources.  
Rio Tinto discovered the Eagle deposit in 2002 and after completion
of pre-feasibility (2005) and feasibility studies (2007), a decision
to build was announced in July 2010. Construction of the project is
now slightly more than 50% completed, with first production expected
to occur in Q4 2014. Total project capex is estimated at $770 million
of which approximately $355 million has already been spent as of the
end of May 2013. In addition to the total acquisition price of
approximately $325 million, remaining investment by Lundin Mining for
the balance of 2013 and 2014 to bring Eagle Mine into production is
estimated at $400 million.  
The Eagle assets being acquired comprise the in-development Eagle
nickel-copper underground mine, the historic Humboldt mill site and
mineral, water, access and surface rights around the mine. The Eagle
deposit is an ultramafic-intrusive-hosted Ni-Cu deposit, with cobalt,
platinum group metals (PGMs) and gold. The mine is located 45 km
north west of the city of Marquette, Michigan and served by good
infrastructure in a region with a long history and local support of
mining activities.  
The underground mine, which is in an advanced stage of development,
is served by a mine ramp, with some 3,000 m of total development
having been completed as of the end of May. The planned mine
production rate is 2,000 tonnes per day from long-hole open stopes
with cemented rock backfill. Ore will be transported from the mine to
the Humboldt mill site on upgraded existing roads (approximately 105
km) by truck.  
Mill facilities are under construction as a brownfields project by
refurbishing the Humboldt mill buildings and infrastructure.
Processing at a rate of 2,000 tonnes per day, will comprise
conventional crushing, grinding and flotation to produce separate
nickel and copper concentrates. The concentrates will be transported
by existing rail infrastructure from the mill site to final smelter
or port destinations. Tailings will be deposited sub-aqueously in the
adjacent flooded Humboldt open pit. Power is supplied from the grid
already connected to the site.  
Transaction Overview 
The purchase price will be paid in cash and is subject to certain
adjustments dependent on the exact time of closing. The purchase
price will be funded from Lundin Mining's current net cash balance of
approximately $250 million and a portion of its existing $350 million
revolving credit facility. The remaining balance of project capital
to be spent will be funded by the Company's existing credit facility,
from ongoing cash flow and if necessary from an expanded debt
facility or similar flexible funding instrument. The transaction is
not conditional upon financing.  
The purchase agreement includes typical closing conditions, including
regulatory approvals. The transaction is expected to be completed in
July 2013. 
Probable Ore Reserves  
As reported by Rio Tinto, Probable Ore Reserves, estimated in
accordance with JORC as of 31 December 2012 (using a cut-off of
NSRgreater than $118/tonne) are shown below. Lundin Mining intends to
file a NI 43-101 Technical Report on the Eagle project within 45

The reserve estimates reported in this release have been prepared by
Rio Tinto, using accepted industry practice and have been classified
in accordance with the JORC Code. There are no material differences
between the definitions of Proven and Probable Mineral Reserves under
the applicable definitions adopted by the Canadian Institute of
Mining, Metallurgy and Petroleum (the "CIM Definition Standards") and
the corresponding equivalent definitions in the JORC Code for Proven
and Probable Ore Reserves. 
The Probable Ore Reserves have been calculated using Net Smelter
Return (NSR) values. The NSR is calculated on a recovered payable
basis taking into account nickel, copper, gold, platinum and
palladium grades, metallurgical recoveries, prices and realization
