TORONTO, ONTARIO–(Marketwire - Oct. 26, 2011) - Lundin Mining Corporation (TSX:LUN)(OMX:LUMI) (“Lundin Mining” or the “Company”) today reported net income of $12.4 million ($0.02 per share) for the third quarter of 2011 and year-to-date net income of $141.3 million ($0.24 per share).

Paul Conibear, President and CEO commented, “At Neves-Corvo, mining and milling volumes continued at high levels, but lower overall grades in the quarter resulted in reduced metal production and consequently higher cash costs on a per pound basis. These higher costs as well as declining metal prices significantly impacted our operating earnings. During late September we moved into higher grade stopes and this contributed to improved production compared to the previous period. Significant increases in production are expected in the fourth quarter as we continue mining in high grade areas.

Zinkgruvan incurred operating issues with both its zinc and copper grinding mills which affected production. The copper mill gearbox was repaired and was back on line in September and a zinc mill vibration issue is expected to be resolved by the end of October to get back up to full production.

Our investment in Tenke achieved new important milestones during the quarter, with the Phase 2 expansion feasibility study being completed by Freeport. The project paid off the remaining $32.0 million on the Excess Overrun Cost facility and Lundin Mining also received its first cash distribution of $7.8 million for total benefit of $39.8 million during the quarter. Both these milestones illustrate the important contribution that Tenke is making to the Company’s future.”

Summary financial results for the quarter are as follows:

Highlights

• Copper and zinc production improved over the previous quarter; however, production at both Neves-Corvo and Zinkgruvan was curtailed due to a number of issues. We continued to mine low grade stockwork ores at Neves-Corvo and consequently plant recoveries were lower than planned. At Zinkgruvan, production shortfalls were experienced due to grinding mill related issues in both circuits. Action has been taken to resolve these issues to enhance fourth quarter production.

Total production was as follows:

• Operating earnings1 for the current quarter of $48.7 million was lower than the $121.5 million reported in the third quarter of 2010. Unfavourable price and price adjustments ($22.9 million effect), lower volume ($11.4 million effect), higher per unit costs ($18.7 million effect), suspension of mining activities at Aguablanca ($19.2 million effect) and foreign exchange ($7.6 million effect) all contributed to the negative variance.
• Net income of $12.4 million ($0.02 per share) was $53.6 million lower than the $66.0 million ($0.11 per share) reported for the third quarter of 2010. The decrease was largely the result of lower operating earnings ($72.8 million), losses on marketable securities of $11.8 million and an unfavourable tax assessment in Spain for the 2004 to 2006 taxation years ($12.5 million tax plus $2.7 million interest). This was partially offset by foreign exchange gains of $36.5 million.
• Cash flow from operations, before changes in non-cash working capital items, for the current quarter was an inflow of $23.7 million, compared to an inflow of $94.2 million for the corresponding period in 2010. The decrease of $70.5 million relates mainly to lower earnings. Cash flow from operations does not include cash flow related to Tenke. During the quarter, our share of available cash from Tenke contributed to a $32.0 million final repayment, discharging the Excess Overrun Cost (“EOC”) facility for the completed Phase 1 project, and we received an additional $7.8 million cash distribution.
• The Neves-Corvo Zinc Expansion plant was started up on time and on budget in July. Given the continued high ratio between copper and zinc price, in August this new circuit was converted to copper ore processing and the Company plans to run the new circuit on copper ore until year-end to achieve higher margins.
• In August, a new mine contractor was mobilized to the Aguablanca nickel/copper mine to commence pit push-backs and reinstatement of the pit haul ramp. The restart of Aguablanca concentrate production remains on schedule for the third quarter of 2012. An underground mining study was also initiated, intended to define potential high grade underground feed to supplement open pit production.
• In September, 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 examined further in conjunction with assessing exploitation concepts for the Semblana copper discovery. The Company has initiated the Neves-Corvo Future Underground Materials Handling Study to assess medium and long-term underground deposit access and extraction infrastructure, including potential benefits of a second deeper shaft.
• During the quarter, the analysis of an extensive 3D seismic geophysics survey across the Neves-Corvo concessions yielded the identification of 19 new drill targets all within the depth horizon of existing mine workings, and at similar elevations to Semblana and Lombador. Exploration budgets were increased and these targets will be progressively tested over the year ahead.
• Exploration programs on the Company’s own assets are being increased in response to drilling success at all current programs including our Irish exploration projects.

Tenke Fungurume

• For the quarter ended September 30, 2011, Tenke production was 32,249 tonnes of copper; 29,702 tonnes of copper were sold at an average realized price of $3.46 per pound.
• During the quarter, the Company benefited from total distributions of $39.8 million from its investment in Tenke:
• The Company fully repaid the remaining $32.0 million on the EOC facility related to its proportionate share of the Phase 1 development; and
• Received its first cash return of $7.8 million.

Attributable cash flow from Tenke, including repayments of the EOC facility, was as follows:

• The Phase 2 Expansion feasibility study to optimize the current plant and increase capacity has been completed under the direction of the operator, Freeport-McMoRan Copper & Gold Inc. (“FCX” or “Freeport”). FCX plans to expand the mill rate to 14,000 tonnes per day through the investment of approximately $850 million (Lundin Mining’s share approximately $250 million). The expansion includes the completion of mill upgrades, acquisition of additional mining equipment, construction of a new tankhouse and a sulfuric acid plant expansion all targeted for completion in 2013. The Phase 2 Expansion is expected to take total plant production of copper cathode up to approximately 195,000 tpa. Early works on this expansion, funded by the partners and from excess cash flow from operations, continued on site during the quarter.

Financial Position and Financing

• Net cash(1) at September 30, 2011 was $208.7 million compared to $125.7 million at September 30, 2010 and $308.2 million at June 30, 2011.
  
  The decrease in net cash during the quarter is primarily attributable to income tax payments ($57.5 million), royalty payments ($18.6 million), investment in mineral property, plant and equipment ($35.1 million), the acquisition of Belmore Resources (Holdings) plc ($9.5 million) and net investment costs in Tenke Fungurume expansion and sustaining capital works ($6.4 million).
• Cash on hand at September 30, 2011 was $256.2 million.

Outlook

2011 Production and Cost Guidance

• Overall production targets for 2011 remain largely unchanged from previous guidance; however, we have slightly lowered copper and lead production guidance to be conservative on year-end expectations. C1 cash costs have been updated for forecast production adjustments and changes in forecast metal prices and the US dollar exchange rates with European currencies.

• Neves-Corvo: Although new massive sulphide stopes have been producing high grade feed to the plant since late September (approximately 4% copper feed grades), production guidance for Neves-Corvo has been revised slightly downwards to reflect a conservative estimate of copper production to year-end. Zinc production guidance at Neves-Corvo has also been reduced as the new zinc plant was converted to copper production duty shortly after startup.
  
  Cash cost of copper is expected to increase by $0.15/lb over previous guidance due to higher production costs and lower than expected by-product credits. As a result of these changes, C1 cost guidance for the year is increased from $1.65/lb to $1.80/lb copper.
• Zinkgruvan: Annual zinc production guidance is being lowered by 2,000 tonnes as a result of a precautionary reduction in throughput due to the increase in vibrations in the mill girth gear. The mill will be offline for nine days in October 2011 while the girth gear is being re-set, after which the mill throughput is expected to increase back to its planned rate. By-product lead production is consequently expected to be 2,000 tonnes lower than last guidance figures.
  
  During the third quarter, the relatively new copper circuit grinding mill gear box failed and down-time has resulted in reduced copper production expectations for the year. The repaired gear box is now in place but copper production guidance has been lowered to 1,500 tonnes for the year to account for the schedule disruption.
  
  Cash cost of zinc is expected to increase from $0.21/lb to $0.32/lb partly due to lower production noted above. In addition, by-product credits are expected to be lower as a result of the recent decline in metal prices and lower copper/lead production.
• Aguablanca: The new mining contractor has started pre-stripping operations. First concentrate production continues to be on schedule for the third quarter of 2012.
  
  Guidance on timing and total investment of €40 million to re-commence ore production is maintained.
• Galmoy: The mine closure plan has been approved by the authorities. Zinc and lead production continue to exceed targets and thus zinc annual guidance has been increased to 31,000 tonnes.
• Tenke: Copper production guidance has been maintained; however, as reported by Freeport, the cash cost guidance is increased to $1.03/lb copper based on expected sales volumes and cost estimates, assuming an average cobalt price of $14/lb for the fourth quarter of 2011.

1 Net cash is a Non-IFRS measure defined as available unrestricted cash less financial debt, including capital leases and other debt-related obligations.

2011 Capital Expenditure Guidance

• Total capital expenditure for the year is expected to be approximately $290 million, unchanged from the initial guidance outlined in the Company’s MD&A for the three months ended March 31, 2011. The $120 million of capital expenditures for Tenke is being funded by a combination of cash calls and profits generated by the mine.

Preliminary 2012 Production Guidance

Based on preliminary budgets in hand for 2012, the following are initial projections for 2012 production from the Company’s mines:

• The copper production profile of Neves-Corvo declines from previous years due predominantly to remaining reserves being lower grade stockworks (< 3% Cu), which also provide for less predictable ore characteristics and lower plant recoveries. Consequently mine planning methods are being revised and a more conservative approach has been taken for preliminary 2012 production guidance. Zinc production for the year ahead is expected to be at least 30,000 tonnes.
• Although Zinkgruvan production for the year ahead is expected to see modest increases in all metals, it will be substantially the same as the current year with some upside potential depending on success in plant debottlenecking.
• Aguablanca forecasts contemplate the mine restarting concentrate production in the third quarter of 2012 and ramping up by year-end.
• Galmoy high grade mining is expected to conclude in the first half of the year.
• Tenke production guidance is not available pending Freeport providing its company-wide annual forecast.
• Production optimization for 2012 along with five year planning will occur over the next two months. 2012 metal production guidance is expected to be updated in December following Board approval of budgets.
