VANCOUVER, BRITISH COLUMBIA–(CCNMatthews - April 17, 2007) - Lundin Mining Corporation (“Lundin Mining” or the “Company”) (TSX:LUN)(AMEX:LMC)(SSE:LUMI) is pleased provide the following first quarter 2007 operating results.

Joao Carrelo, COO of Lundin Mining, commented: “During the first quarter of 2007 we have achieved record throughput at both the Neves-Corvo and Zinkgruvan mines. The Neves-Corvo mine set a record for tonnes hoisted in a quarter and the Zinkgruvan mine set a record for tonnes milled in a quarter. Production of contained copper metal at Neves-Corvo increased by 21.5% as compared with the first quarter 2006. A significant milestone was achieved at Neves-Corvo in February, when total production of copper metal, since start-up, reached 2 million tonnes. These results reflect the commitment of our workforce and the productivity gains achieved as we endeavour to maximize the value of our assets and secure the competitive advantage of our operations.”

The following information is provided as if the companies (Lundin Mining Corporation and EuroZinc Mining Corporation) had operated on a combined basis since the first period presented. EuroZinc Mining Corporation was consolidated in Lundin Mining as at November 1, 2006.

- Hatch was awarded a contract to undertake the Bankable Feasibility Study of the Ozernoe Project

Mine Operations Highlights, First Quarter 2007

Neves-Corvo

- Mined 647,596 tonnes of ore in the first quarter 2007, a 32% increase as compared with the first quarter 2006. This represents the largest tonnage mined in one quarter in the mine’s 19 year history.

- Copper production for the quarter was 21.5% above the comparable period in 2006 primarily due to an increase in the head grade. The mill feed grade in the first quarter 2007 was 5.0% copper as compared with 4.2% in the first quarter 2006.

- The copper recovery was 87.1% in the first quarter 2007 as compared with 89.3% in the comparable period in 2006.

- Zinc production was 6,193 tonnes metal contained in concentrate in the first quarter 2007. Zinc head grades were 8.8% in the period. There was no zinc production in the comparable period in 2006.

Zinkgruvan

- Mined 224,696 tonnes in the first quarter 2007, a 30% increase in tonnage as compared with the first quarter in 2006.

- Ore processed during the first quarter 2007 exceeded the comparable period in 2006 by 65,625 tonne, or 38.7%, and was 235,390 tonnes. This represents the largest tonnage milled in one quarter in the mine’s history.

- Feed grades of zinc, lead and silver were lower in first quarter 2007 compared with the first quarter 2006, which is in accordance with the valid mine plan.

- Production of zinc metal contained in concentrate was 4.4% lower in first quarter 2007 compared with the first quarter 2006 and ended up at 17,162 tonne.

- Production of lead metal contained in concentrate was 10.9% higher in first quarter 2007 compared with the first quarter 2006 and ended up at 8,643 tonne.

- The recovery of zinc remained at a high level and was 94.1% in the quarter.

- Lead and silver recoveries were lower in the first quarter 2007 compared with the first quarter 2006 at 87.5% and 72.4% respectively.

Galmoy

- Mined ore was 93,470 tonnes in the first quarter 2007 compared with 149,617 tonnes of ore in the same period in 2006.

- Production in January and February was below normal levels, due to the delays in negotiations between management and the unions which in turn negatively impacted the production of concentrates at the mine and due to the tragic accident in February when the mine was at stand-still for eight days.

- Due to the sequence of mining activities, run of mine ore grades were 12.8% zinc per tonne and 3.5% lead per tonne compared with 13.2% zinc per tonne and 4.3% lead per tonne in the first quarter 2006.

- Run of mine ore grades were lower in the first quarter 2007 compared with the first quarter 2006 due to the sequence of mining activities. Grades were 12.8% zinc per tonne and 3.5% lead per tonne, which is in accordance with the valid mine plan.

- Zinc recovery was 83.0% in the first quarter 2007 as compared with 83.9% in the comparable period 2006, at a lower zinc head grade in the first quarter 2007.

- Lead recovery was 73.2% in the first quarter 2007 as compared with 66.6% in the comparable period 2006. At a lower lead head grade the recovery exceeded expectations.

- The higher lead recovery is due to the installation of a new flotation cell which was commissioned in the first quarter 2007.

- During the first quarter 2007 modifications to the zinc flotation circuit were completed to increase flotation capacity. This is expected to increase zinc recovery.

Storliden

- The new Life Of Mine Plan will provide for three additional months of production compared to the previous plan.

- Ore mined during the first quarter of 2007 was 76,898 tonnes, as compared with 80,400 tonnes in the first quarter 2006.

- Ore milled during the first quarter of 2007 was 64,547 tonnes, which was somewhat below budget. This shortfall will be milled in the beginning of April.

The following table highlights the production results for the first quarter 2007 and 2006 and for the year 2006.

Mine Development Projects Highlights, First Quarter 2007

Ozernoe

- The planned second phase of drilling, including resource variography, structural, geotechnical and geometallurgical drilling is nearing completion. Preliminary results of this drilling have been positive. Metallurgical test work on composite core samples is planned to start over the next 2-3 months.

- Hatch has been awarded the contract for the Initial Phase of Work leading to the Bankable Feasibility Study. Detailed work will commence mid-May.

- Site work, in addition to the drilling, is underway to develop permanent camp facilities and other basic infrastructure required to develop this resource.

- Management and support staff personnel are also being recruited and employed as project momentum accelerates.

Aljustrel

- Underground development at the Moinho mine is virtually on target and is now close to reaching the 380 level, which is the bottom extraction level of the mine. At Feitais mine, adverse but localized ground conditions hampered development rates during the first quarter, nevertheless, the resulting delays are expected to be recovered to meet the scheduled development of the 430 level, which constitutes the lower level of extraction.

- At the treatment plant preparation work is on track, although delays are expected in the supply of some equipment. Most major equipment has been ordered and construction crews are being reinforced to secure scheduled civil construction work.

The Company plans to release the first quarter 2007 financials before the opening of trading on the 10th of May, and a conference call will be held on the 10th of May.

Lundin Mining is a rapidly growing, mid-tier mining company engaged in the acquisition, exploration, development and mining of base metal deposits internationally. The Company currently owns four mines in operation; the Neves-Corvo mine in Portugal, the Zinkgruvan and Storliden mines in Sweden, and the Galmoy mine in Ireland.
