Lundin Mining Recommences Production at Aguablanca

TORONTO, ONTARIO–(Marketwire - Aug. 27, 2012) - Lundin Mining Corporation (“Lundin” or the “Company”) (TSX:LUN)(OMX:LUMI) is pleased to announce that production at the wholly owned Aguablanca nickel/copper mine in Spain has restarted ahead of the previously announced schedule. While full production ramp-up is expected to be achieved in Q4/2012, the mill is treating a substantial stockpile of ore at good throughput rates and first concentrate shipments have started to arrive at the port warehouse.

Mr. Paul Conibear, President and CEO of the Company stated, “We are very pleased with the successful execution of our re-start plan and are being able to commence concentrate production slightly ahead of schedule. The operation provides nickel and additional copper production for the Company, and is expected to generate good positive cash flows at current metal prices.”

Consistent with the company’s recently increased production guidance, Aguablanca is forecasted to produce between 1,000 - 1,500 tonnes of nickel and a similar volume of copper in 2012. Also as previously guided, the operation is expected to produce between 5,000 - 7,000 tonnes of both nickel and copper in 2013 and between 6,000 - 7,000 of both nickel and copper in 2014. Cash cost guidance will be confirmed prior to year end, once full design rates have been achieved in the plant.
