Lundin Mining Corporation: LUNDIN MINING ANNOUNCES MAIDEN MINERAL RESERVE ESTIMATES FOR TWO NEW OREBODIES AT CANDELARIA

Toronto, April 7, 2015 (TSX: LUN; Nasdaq Stockholm: LUMI) Lundin Mining Corporation ("Lundin" or the "Company") is pleased to announce that maiden Mineral Reserves have been estimated on two recently discovered orebodies at Candelaria, known as Susana and Damiana, located to the immediate south and below the current open pit.

In addition, the Company has also re-estimated the total Candelaria open pit Mineral Reserves with refined economic parameters. Open pit reserves now include portions of the Susana and Damiana mineralization that are contained within the new open pit shell.

The Mineral Reserves have been estimated in accordance with National Instrument 43-101 and are reported as of April 01, 2015. Highlights include:

-- Maiden underground Proven and Probable Reserves at Susana and Damiana consist of 14.9 Mt at average grades of over 1.0% copper -- The new underground Reserves are expected to be accessed from existing and new portals from the open pit and will form important additions to the current underground operations -- After adjusting for the effects of mining depletion and refined economic parameters, the updated open pit Mineral Reserves reflect an increase of approximately 24% (or 66.3 Mt at 0.58% Cu) from the previous estimate dated at Dec. 31, 2013 -- Of this 66.3 million tonnes, 27.9 million tonnes (at higher grades of 0.68% copper, 0.16 g/t gold and 2.31 g/t silver) are from the new Susana and Damiana orebodies -- The increased open pit and underground Mineral Reserves are expected to result in approximately three years of additional mine life for the Candelaria operation

Commenting on the updated Mineral Reserve estimate, Mr. Paul Conibear, President and CEO of Lundin Mining stated, "We are very pleased that in a short amount of time we have been able to deliver meaningful additions to the Mineral Reserves at Candelaria. With ten drills currently active on step out drilling across the five different underground orebodies, we continue our aggressive 2015 exploration program, the results of which will be included in our third quarter corporate Reserve and Resource update. These results and efforts from ongoing mine planning will form the basis of our optimized Candelaria district mine plan which is expected to be released in the third quarter of this year."
