Lundin Mining Q4 and Full Year 2012 Production Results17:00 EST Tuesday, January 22, 2013TORONTO, ONTARIO--(Marketwire - Jan. 22, 2013) -Lundin Mining Corporation (TSX:LUN)(OMX:LUMI) ("Lundin Mining" or the "Company") reports the following production results for the fourth quarter and full year 2012:Metal Production(contained tonnes)FY 2012Q4 2012Copper, wholly-owned operations63,87814,224Tenke attributable (24%)38,17210,669Total Copper102,05024,893Zinc122,20429,161Lead38,4648,353Nickel2,3981,705Paul Conibear, President and CEO commented, "We are pleased to achieve the high-end of our production guidance targets for 2012 at each of our operations. Zinkgruvan had a particularly successful year with new records set for production of zinc, lead and copper. Tenke also set new copper production records as Phase II expanded facilities came on line. All of our assets are very well positioned to deliver a solid performance again this year."Segmented production and guidance is as follows: (contained tonnes)2012 Production Results2012 Production Guidance2013 GuidanceProductionC1 Costb,cCopperNeves- Corvo58,55955,000 - 60,00050,000 - 55,000$1.80/lbZinkgruvan3,0593,000 - 4,0002,500 - 3,500Aguablanca2,2601,500 - 2,0004,500 - 5,000Wholly-owned63,87859,500 - 66,00057,000 - 63,500Tenke (@24%)38,17236,20044,650a$1.03/lbTotal attributable102,05095,700 - 102,200101,650 - 108,150ZincNeves-Corvo30,00625,000 - 30,00045,000 - 50,000Zinkgruvan83,20977,000 - 83,00073,000 - 78,000$0.20/lbGalmoy (in ore)8,9898,500 - 9,000nilTotal122,204110,500 - 122,000118,000 - 128,000LeadNeves-Corvo87nilnilZinkgruvan37,24634,000 - 39,00033,000 - 36,000Galmoy (in ore)1,1311,000 - 1,100nilTotal38,46435,000 - 40,10033,000 - 36,000NickelAguablanca2,3981,500 - 2,0005,000 - 5,500$5.00/lba. Freeport has provided 2013 sales guidance which has been assumed to approximate Tenke's production.b. Cash costs remain dependent upon exchange rates (EUR/USD: 1.30, USD/SEK: 6.75) and metal prices (Cu: $3.50, Zn: $0.95, Ni: $8.00, Co: $12.00).c. Cash cost is a non-GAAP measure reflecting the sum of direct costs less by-product credits.Operational CommentaryNeves-Corvo: Total copper production exceeded the original guidance for the year, however overall grade of copper ore was lower than planned due to an exceptional quantity of lower grade but profitable "Out of Reserve" ore that was encountered and mined but was not part of the original mineral reserve estimate. Approximately 42% of the copper ore mined in 2012 was Out of Reserve. In the new copper mining zone of Lombador, 57% of the material mined was Out of Reserve. Overall for 2012, Out of Reserve material graded an average of 1.75% copper as compared to the Reserve material mined which graded 3.28% copper. Net benefits of mining and processing this Out of Reserve material include an extended mine life and overall long term higher aggregate revenues. Underground drilling will be increased significantly for 2013 to better define the extent of mineralization not currently in the reserve estimates and mine plans. Despite the lower than planned feed grades, Neves-Corvo copper plant performance was excellent with 88.2% recovery achieved. Ramp-up of the zinc plant continued in the quarter, with throughput approximately 75% higher than the prior quarter and record quarterly, and annual, zinc metal production was generated. Zinkgruvan: As expected, lower zinc and lead grades were realized in the fourth quarter, though the impact on metal production was partially mitigated by higher volumes processed than the prior two quarters and continued high recovery performance in the process plant. Zinc, copper and lead grades and plant recoveries met and in some cases were better than originally anticipated. Zinkgruvan finished the year with record production of zinc, lead and copper metal in concentrate. Aguablanca: Processing operations re-commenced in August, with full production achieved earlier than planned in the fourth quarter of 2012, resulting in higher than expected nickel and copper metal in concentrate production. Grades mined and plant recoveries achieved for both nickel and copper were slightly better than expected. Galmoy: Mining production from remnant ores exceeded expectations for the year. Mining ceased in the fourth quarter of 2012, though processing of stockpiled ore, by a third party processing facility, will continue into 2013. The mine closure plan has been approved by regulating authorities. Tenke: During 2012, Tenke achieved record mining and production rates facilitated by the staged commissioning of Phase II expansion facilities. The Phase II expansion is substantially complete, on schedule and on budget. By year end, the expanded facilities were operating near full Phase II design capacity and as reported by Freeport as Operator, overall fourth quarter production of 44,452 tonnes of copper cathode was 91% of the expanded annual design capacity of 195,000 tpa copper cathode. Freeport has provided 2013 metal sales guidance of 186,000 tonnes of copper cathode and 13,600 tonnes of cobalt (contained in cobalt hydroxide product).
