TORONTO, ONTARIO–(Marketwire - Feb. 22, 2012) - Lundin Mining Corporation (TSX:LUN)(OMX:LUMI) (“Lundin Mining” or the “Company”) today reported net earnings of $183.8 million ($0.32 per share) for the fiscal year ended December 31, 2011 and $42.5 million for the fourth quarter of 2011 ($0.07 per share).

Paul Conibear, President and CEO commented, “We ended the year with a strong quarter of production, achieving record tonnages of ore mined and milled at both our Neves-Corvo and Zinkgruvan mines. These production records occurred in parallel to achieving the best annual safety record in the Company’s history, attesting to improvements made in operations company wide.

The successful start up of the expanded zinc plant at Neves-Corvo in mid-2011 has positioned the mine to become a significant by-product producer of zinc. In parallel we advanced other internal growth studies to develop strategies to access deeper Lombador mineralization and the exploitation of Semblana. We also have committed to our largest exploration program ever for 2012 to extract value from the multiple new high potential exploration targets in and around Neves-Corvo.

Internally we have staffed up in our corporate development, technical and project execution capabilities and have begun to evaluate new growth opportunities.

Tenke finished the year with strong production results and we are very excited about construction progress being made on the Phase II expansion. The significant contribution this outstanding copper operation makes to the Company is becoming quite evident and several catalysts for increasing asset value in the year ahead are expected as expanded production milestones are achieved.

As the year progressed the Company achieved improved operating cashflow, and we ended the year with a healthy balance sheet and a strong net cash position.”

Highlights

A strong fourth quarter of production generated higher than guided copper production while zinc and lead production ended the year essentially in line with expectations.

• At Neves-Corvo, ore mined and milled reached record levels. For five consecutive years, Neves-Corvo has exceeded the previous year’s volume of copper ore mined.
• Zinkgruvan also reached new record levels of ore mined and milled and it ended the year with its best quarter of zinc and copper production.
• At Aguablanca, significant progress has been made in re-establishing the pit ramp ahead of restart of nickel/copper mining operations scheduled for the second half 2012.
• Mining of remnant high grade ore and associated profits from Galmoy continued throughout the year and this provided a better than expected contribution to the Company’s cash position.
• Regarding safety performance, in 2011, Total Recordable Incident Frequency was the lowest in the Company’s history at 1.61. A similar reduction was achieved in the frequency of Lost Time Incidents for the year.
• The Company also achieved successful environmental performance with no significant incidents during the year.

• Operating earnings1 decreased by $87.9 million from $461.7 million in 2010 to $373.8 million in 2011 and sales decreased from $849.2 million in 2010 to $783.8 million in 2011. Both the decreases in sales and operating earnings1 were largely attributable to the suspension of operations at Aguablanca which had a negative impact of $60.8 million on comparative operating earnings and $131.7 million on sales.
• Excluding Aguablanca, operating earnings for the year were $390.5 million, only $27.1 million lower than the $417.6 million attributable to 2010. Favourable price and price adjustments ($40.8 million) and higher sales volume ($18.8 million) were more than offset by the effect of higher costs of $61.3 million. In addition, the € and SEK both strengthened against the US dollar in 2011 compared to 2010, resulting in a further increase in operating costs of $25.4 million.
• Sales, excluding Aguablanca, increased by $66.3 million from $719.4 million in 2010 to $785.7 million in 2011. Higher metal prices ($40.8 million) and an increase in sales volume ($25.5 million), particularly at Galmoy, contributed to the overall increase.
  
  Average 2011 metal prices for copper and lead were higher by 17% and 12%, respectively, while the average price for zinc remained relatively unchanged compared to 2010.
• Operating costs (excluding depreciation) increased by $14.7 million year on year; excluding Aguablanca, the increase was $85.5 million and is primarily attributable to:
  • Neves-Corvo ($53.4 million): higher production cost in 2011 associated with the mining of lower grade ore and the increased use of contractors, partially offset by a one-time prior period royalty charge in 2010 of $8.1 million;
  • Zinkgruvan ($25.4 million): higher unit costs and the strengthening of the SEK against the US dollar; and
  • Galmoy ($6.7 million): more than doubling of ore mined and metal produced.
• General and administrative expenses increased by $7.8 million. Corporate development costs of $6.8 million were incurred in 2011 associated with the planned merger with Inmet Mining Corporation (“Inmet”), responding to Equinox Mineral Limited’s (“Equinox”) unsolicited take-over bid and the Company’s subsequent strategic review.
• Net earnings of $183.8 million ($0.32 per share) were $122.5 million less than the $306.3 million ($0.53 per share) reported in 2010. In addition to lower operating earnings1 of $87.9 million, the decrease in net earnings was related to:
  • higher depreciation ($31.9 million) as a result of increase in ore mined, commissioning of the new zinc expansion at Neves-Corvo and the new copper mill at Zinkgruvan;
  • lower net finance income ($49.2 million) due to higher revaluation gain on marketable securities of $39.9 million and gain on derivatives contracts of $10.2 million recorded in 2010; and
  • goodwill impairment of $35.7 million related to Aguablanca; partially offset by
  • increase in equity earnings from investment in Tenke Fungurume ($18.8 million), and lower income taxes.
• Cash flow from operations for the year was $308.7 million compared to $276.1 million for 2010. The decrease in operating earnings1 of $87.9 million is offset by the net increase in non-cash working capital change of $89.1 million. Also, included in 2010 is the cash outflow of $30.6 million that the Company paid to settle its derivative contracts.
• An impairment analysis on the Aguablanca operation concluded that the recoverable value of the mine’s net assets were lower than their carrying value. Accordingly, a $35.7 million impairment loss was measured and was allocated to goodwill during the fourth quarter of 2011.
• In August, a new mine contractor was mobilized at Aguablanca to commence pit push-backs and reinstatement of the pit haul ramp. The restart of Aguablanca concentrate production is expected in the second half of 2012. An underground mining study was also initiated intended to define potential high grade underground feed to supplement open pit production.
• The Neves-Corvo Zinc Expansion project was completed in July 2011 on budget and on schedule. Given the continued high price ratio of copper to zinc, this new circuit was converted to processing copper ore until the end of the year for better margins.
• In September 2011, the Company released the results of a Feasibility Study on the Lombador Phase I development demonstrating that the exploitation of the upper portions of the Lombador zinc/copper ore bodies could extend the mine life to at least 2026 and create a platform for further extensions. The optimal development plan for Lombador is being further examined in conjunction with assessing exploitation concepts for the Semblana copper discovery.
  
  Initial results of the Future Underground Materials Handling Study indicated two preferred options to pursue the exploitation of the deeper portions of the Lombador copper/zinc resource and the Semblana copper deposit (see news release dated January 23, 2012 entitled “Lundin Mining Reports on Neves-Corvo Future Underground Materials Handling Study”). Additional review is underway, taking into account ongoing exploration results, to further assess the two options.

Tenke Fungurume

• Another milestone at Tenke Fungurume was achieved through the formal announcement of the advancement of the $850 million Phase II Expansion which will bring total production capability to 195,000 tonnes per annum (“tpa”) of copper cathode with associated cobalt. The expansion includes the completion of mill upgrades, acquisition of additional mining equipment and construction of a new tankhouse. Construction on this major expansion was well advanced by 2011 year end and is tracking on schedule and on budget, targeting completion in first quarter 2013.
• Milling facilities at the Tenke Fungurume mine continued to perform well with throughput averaging 11,100 metric tons of ore per day in 2011.
• For the year ended December 31, 2011, Tenke produced 127,367 tonnes of copper and sold 128,284 tonnes at an average realized price of $3.74 per pound. During the year, 11,182 tonnes of cobalt in hydroxide was produced and 11,515 tonnes were sold at an average realized price of $9.99 per pound.
• Attributable operating cash flow at Tenke Fungurume for 2011 was $149.4 million.
• During the third quarter of 2011, the Excess Overrun Cost facility (“EOC facility”), related to the Company’s proportionate share of the Phase I development at Tenke, was fully repaid enabling the Company’s share of ongoing surplus cash from operations to be utilized to fund the Phase II Expansion.

Financial Position and Financing

• Net cash1 at December 31, 2011 was $236.1 million compared to a net cash1 position $159.2 million at the end of 2010.
• The $76.9 million increase in net cash during the year was primarily attributable to cash flow from operations ($308.7 million), including $54.8 million generated from working capital offset by: investment in mineral property, plant and equipment ($179.1 million), investment in Tenke Fungurume expansion and sustaining capital works ($64.5 million) and net repayment of debt ($10.5 million). Cash on hand at December 31, 2011 was $265.4 million.

Outlook

2012 Production and Cost Guidance

• 2012 production targets and a three year production look ahead for wholly-owned operations remains unchanged from the guidance provided on December 12, 2011 (see news release entitled “Lundin Mining Provides Operating Outlook for 2012-2014”). 2012 guidance is as follows:

• Neves-Corvo: Copper production is expected to be reduced from previous years as remaining reserves are lower grade stockworks which provide for less predictable ore characteristics, lower recoveries and higher costs. Zinc production is expected to be at least 30,000 tonnes.
• Zinkgruvan: Zinc, lead and copper production are expected to see modest increases compared to 2011 with further upside potential depending on plant de-bottlenecking initiatives.
• Aguablanca: Production is expected to resume in the second half of 2012. Reserves represent approximately five years of production, averaging 7,500 tonnes of nickel and 6,500 tonnes of copper per annum.
• Galmoy: High grade mining is expected to conclude in the first half of 2012, with sales continuing to be recognized into early 2013 as stockpiled ore is milled at a third party processing facility.
• Tenke: Freeport, the mine’s operator, expects sales of copper to increase to 131,500 tonnes with sales volumes of cobalt comparable to 2011. The Phase II expansion project to 195,000 tpa of copper cathode (production on a 100% basis) is expected to be completed in first quarter 2013.

2012 Capital Expenditure Guidance

Capital expenditures for 2012 are now expected to be $370 million. This represents a $40 million reduction from our previously released estimate of December 12, 2011. The change is a result of updated figures for new investment in Tenke, and our guidance now includes:

• Sustaining capital in European operations: $95 million (2011 - $127 million). The decrease is related to slightly lower sustaining capital expenditures at Neves-Corvo for the year ahead.
• New investment capex in European operations: $65 million (2011 - $52 million), consisting of:
  • Lombador Phase I ($40 million) including underground development, final SAG mill delivery payments and other critical path items.
  • Neves-Corvo dam ($13 million) related to tailings and water storage capacity increases.
  • Other plant improvements and debottlenecking initiatives ($12 million) at both Neves-Corvo and Zinkgruvan.
• New investment in Tenke: Freeport expects the Phase II expansion at Tenke will be completed by the first quarter of 2013. Lundin Mining’s share of expansion funding and sustaining capital funding may be up to $210 million for 2012. As guided by Freeport, total capital expenditure for the Phase II Expansion is expected to be $850 million. If metal prices remain strong, the capital spend is expected to be cash neutral to the Company, as Tenke’s operating cash flows should be sufficient to meet this capital funding requirement.

Exploration Investment

Exploration expenditures are expected to increase from $42.6 million in 2011 to $50 million in 2012. Approximately $34 million of this will be spent at Neves-Corvo, where a 90,000 metre surface drilling program is planned for 2012 which will continue to test resource expansion targets at Semblana in addition to drill-testing the multiple high priority targets recently identified within the Neves-Corvo near mine area. In addition, the 2012 exploration program is expected to test several greenfield targets in the Iberian region, as well as continued resource definition drilling at the Company’s Clare and Lakelands exploration projects in Ireland.
