Lundin Mining Corporation First Quarter Results ended March 31, 2013

TORONTO, 04/24/13 -- Lundin Mining Corporation (TSX: LUN)(OMX: LUMI) ("Lundin Mining" or the "Company") today reported net earnings of $50.1 million ($0.09 per share) for the quarter ended March 31, 2013. Cash flows of $45.8 million were generated from operations, not including the Company's attributable cash flows of $43.6 million from Tenke Fungurume.

Paul Conibear, President and CEO commented, "Our focus on operational execution continues in 2013. We remain on track to meet our annual production guidance targets and are well positioned to continue to improve our strong balance sheet throughout the year.

Tenke was clearly the highlight of the quarter, as copper production set another quarterly record and we received cash returns of $45 million from the operation. Based on current metal prices and operating conditions, we expect to continue to receive meaningful amounts of cash distributions from Tenke throughout the remainder of the year.

We are also pleased to announce the closing of the acquisition of the Kokkola cobalt refinery during the quarter. The acquisition will enable immediate entry and value-added vertical integration to the refined cobalt market and will help maximize the value of the cobalt resources at Tenke."

Operational Highlights

Wholly-owned operations: Production and costs were in line with expectations for copper and nickel for the quarter. Zinc and lead production were lower than expected and Zinkgruvan's cash costs were higher than expected for the quarter; however, the Company expects to make up for this shortfall in the balance of the year.

--  Neves-Corvo produced 14,314 tonnes of copper and 10,263 tonnes of zinc
    in the first quarter of 2013. This was record production for zinc in the
    quarter. Copper production was on target and excellent plant recoveries
    were achieved. Cash costs per pound of copper sold were $1.83/lb for the
    quarter, largely in-line with guidance despite the lower than expected
    zinc by-product credits.

--  At Zinkgruvan, backfill system problems necessitated a change to
    underground mine sequencing which impacted both the volume of ore mined
    and head grades for zinc and lead. Backfill system issues have since
    been resolved. Copper production hit a new quarterly record of 1,146
    tonnes. Cash costs per pound of zinc sold were $0.42/lb for the quarter,
    largely impacted by lower by-product credits and the lower volume of
    zinc produced and sold.

--  At Aguablanca, ore milled, grades and plant recoveries for both nickel
    and copper were slightly better than expectations. Cash costs per pound
    of nickel sold were better than guidance, at $4.66/lb.

Tenke: Tenke achieved a quarterly record in mining, milling and copper production.

--  First quarter production amounted to 54,462 tonnes of copper cathode
    aided by record throughput, excellent copper mill feed grades and high
    plant recoveries.

--  Attributable operating cash flow from Tenke for the first quarter of
    2013 was $43.6 million.

--  Excess operating cash flows of $45.0 million were distributed to the
    Company in the first quarter of 2013.

--  Operating cash costs were $1.23/lb of copper sold.

--  Phase II expansion, which included optimizing the current plant and
    increasing mine, mill and processing capacity, was completed,
    highlighted by the commissioning of the balance of the expanded
    electrowinning tankhouse. A second sulphuric acid plant is under
    development and is expected to be operational by 2015.

Financial Highlights

--  Operating earnings for the first quarter of 2013 were $68.1 million, a
    decrease of $37.3 million from the $105.4 million reported in the
    comparable quarter of 2012. The decrease was primarily attributable to
    lower sales volume at Neves-Corvo and Zinkgruvan ($18.3 million) and
    lower metal prices and price adjustments from prior period sales ($27.0
    million), partially offset by earnings at Aguablanca following the
    restart of operations ($15.1 million).

--  For the quarter ended March 31, 2013, sales of $188.2 million decreased
    $24.6 million from the first quarter of prior year ($212.8 million)
    mainly due to lower sales volumes at Neves-Corvo and Zinkgruvan, as well
    as lower realized copper and zinc prices.

--  Average London Metal Exchange ("LME") metal prices for copper and nickel
    for the quarter ended March 31, 2013 were lower (5% and 12%,
    respectively) than that of the comparable quarter in the prior year,
    while lead prices increased 10% and zinc prices remained flat.

--  Operating costs (excluding depreciation) of $113.5 million in the
    current quarter were higher than the prior year comparative quarter
    ($99.8 million) reflecting a full quarter of production at Aguablanca.
    This was partially offset by lower volumes sold at Neves-Corvo,
    Zinkgruvan and Galmoy.

--  Net earnings of $50.1 million ($0.09 per share) for the current quarter
    were $8.2 million lower than the $58.3 million ($0.10 per share)
    reported for the quarter ended March 31, 2012. Earnings were impacted
    by:

    --  lower operating earnings primarily due to lower realized metal
        prices and prior period price adjustments ($37.3 million); and
    --  higher depreciation, depletion and amortization expense ($10.7
        million), reflecting restart of production at Aguablanca; offset by
    --  higher net other income ($25.7 million) representing an increase in
        foreign exchange gain ($10.8 million) and proceeds from an insurance
        claim relating to Aguablanca's ramp failure in 2010 ($15.1 million);
        and
    --  higher income from equity investment in Tenke Fungurume ($6.3
        million).

--  Cash flow from operations for the current quarter was $45.8 million
    compared to $51.3 million in the first quarter of 2012. The comparative
    decrease is attributable to lower net earnings in the current quarter.

Tenke Fungurume

--  The expanded milling facility increased average daily production, with
    throughput averaging approximately 14,600 metric tonnes of ore per day
    during the first quarter of 2013, exceeding the 14,000 metric tonnes of
    ore per day expanded design capacity. Average throughput for the first
    quarter was approximately 2,400 metric tonnes of ore per day higher than
    the comparable quarter from the previous year.

--  For the quarter ended March 31, 2013, Tenke produced 54,462 tonnes of
    copper and sold 53,583 tonnes at an average realized price of $3.40/lb.
    During the current quarter, 2,540 tonnes of cobalt in hydroxide were
    produced and 2,555 tonnes were sold at an average realized price of
    $7.28/lb.

--  Cash cost(1) of $1.23/lb of copper for the quarter was slightly lower
    than the $1.25/lb reported in the prior year comparable quarter,
    primarily reflecting the benefit of higher sales volumes, partly offset
    by lower cobalt credits. For 2013, Freeport-McMoRan Copper & Gold Inc.
    ("Freeport") has revised cash cost guidance to $1.18/lb, from $1.03/lb,
    due primarily to reduced cobalt by-product credits.

--  During the quarter, $17.0 million was spent on the Company's
    attributable share of Tenke's capital requirements which was funded by
    the excess cash flow from operations.

--  Cash distributions of $45.0 million were received from Tenke during the
    quarter ended March 31, 2013 (Q1-2012: nil).

(1) Cash cost/lb of copper are non-GAAP measures defined as all cash costs
directly attributable to mining operating, less royalties and by-product
credits.

Corporate Highlights

--  On March 29, 2013, the Company announced completion of the acquisition
    of 24% of the Kokkola cobalt refinery located in Finland and the related
    sales and marketing business ("Kokkola" or "joint venture"), which will
    provide direct-end market access for the cobalt hydroxide production
    from Tenke.

The Company holds an effective 24% ownership interest in the joint venture, with Freeport holding a 56% ownership interest and being the operator of the joint venture, and La Generale des Carrieres et des Mines, the Congolese state mining company, holding a 20% interest in Kokkola.

The initial consideration paid was $355 million, which included $34 million of acquired cash. Under the terms of the agreement, there is the potential for additional consideration of up to $110 million over a period of three years, contingent upon the achievement of revenue-based performance targets. Lundin Mining's share of initial acquisition costs, including acquired cash, was $116.3 million based on a 30%/70% split with Freeport, which amounts will be repaid prior to any shareholder advances.


Financial Position and Financing

--  Net cash(1) position at March 31, 2013 was $199.4 million compared to
    $265.1 million at December 31, 2012 and $242.3 million at March 31,
    2012.

--  The $65.7 million decrease in net cash during the quarter was primarily
    attributable to the acquisition of Kokkola ($116.3 million) and
    investments in mineral properties, plant and equipment ($36.6 million),
    partially offset by cash flow from operations of $45.8 million and
    distributions from Tenke of $45.0 million.

--  Net cash balance at April 24, 2013 is approximately $214 million.

(1) Net cash is a non-GAAP measure defined as available unrestricted cash
less long-term debt and finance leases.

Outlook

2013 Production and Cost Guidance

--  Production and cash cost guidance for 2013 for the Company's wholly-
    owned operations remains unchanged. Freeport forecasts increased copper
    production at Tenke, up from 44,650 to 47,300 tonnes of cathode (Lundin
    Mining's attributable share), along with increased unit costs, as noted
    herein.

2013 Capital Expenditure Guidance

Capital expenditures for 2013 are expected to be $285 million (unchanged from previous guidance), as described below:

--  Sustaining capital in European operations - $110 million, consisting of
    approximately $70 million for Neves-Corvo and $40 million for
    Zinkgruvan.

--  New investment capital in European operations - $60 million, consisting
    of approximately $30 million for Lombador Phase I, $9 million for an
    industrial dam at Neves-Corvo, $13 million for Zinkgruvan's ore dressing
    plant and other improvement initiatives.

--  New investment in Tenke - $115 million, estimated by the Company as its
    share of the remaining Phase II expansion costs, exploration and Phase
    III and IV expansion related initiatives and sustaining capital funding
    for 2013. All of the capital expenditures are expected to be self-funded
    by cash flow from Tenke operations. Assuming current metal prices and
    operating conditions prevail, the Company expects to continue to receive
    regular distributions from Tenke for the remainder of 2013.
