TORONTO, ONTARIO, Sep 05, 2017 (Marketwired via COMTEX) -- TORONTO, ONTARIO--(Marketwired - Sept. 5, 2017) - Lundin Mining Corporation (LUN)(omx:LUMI)("Lundin Mining" or the "Company") today reported its Mineral Resource and Mineral Reserve estimates as at June 30, 2017. On a consolidated and attributable basis, contained metal in the Proven and Probable Mineral Reserve categories totaled 3,232 kt of copper, 3,415 kt of zinc and 130 kt of nickel.

Commenting on the update, Mr. Paul Conibear, President and CEO of Lundin Mining said "We are pleased that our exploration efforts continue to add great value to our assets. Exploration success at Candelaria has resulted in further significant increases in underground Mineral Resources and Mineral Reserves that will allow us to continue to advance mine plan optimization and mine life extension in Chile. Study work and approval of the Zinc Expansion Project at Neves-Corvo and the Eagle East development at Eagle during the last year have contributed to increased Mineral Reserves at both mines. In the light of improved market conditions, we plan to accelerate exploration at all our mine sites in 2018 as well as advance at least two new copper-focused greenfield exploration projects".

Highlights

Total Candelaria Measured and Indicated MineralResources have increased by approximately 7.5% to 740.9Mt at 0.70%Cu, from 689.0 Mt at 0.64% Cu reported as of June 30, 2016, reflecting thecontinued success of the exploration campaigns.

Cautionary Notes to Investors - Mineral Resource and Reserve Estimates

In accordance with applicable Canadian securities regulatory requirements, all Mineral Reserve and Mineral Resource estimates of the Company disclosed or incorporated by reference in this news release have been prepared in accordance with Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects adopted by the Canadian Securities Administrators ("NI 43-101") and are classified in accordance with the Canadian Institute of Mining Metallurgy and Petroleum's "CIM Definition Standards for Mineral Resources and Mineral Reserves" adopted on May 10, 2014 (the "CIM Standards").

Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. Pursuant to the CIM Standards, Mineral Resources have a higher degree of uncertainty than Mineral Reserves as to their existence as well as their economic and legal feasibility. Inferred Mineral Resources, when compared with Measured or Indicated Mineral Resources, have the least certainty as to their existence, and it cannot be assumed that all or any part of an Inferred Mineral Resource will be upgraded to an Indicated or Measured Mineral Resource as a result of continued exploration. Pursuant to NI 43-101, Inferred Mineral Resources may not form the basis of any economic analysis, including any feasibility study. Accordingly, readers are cautioned not to assume that all or any part of a Mineral Resource exists, will ever be converted into a Mineral Reserve, or is or will ever be economically or legally mineable or recovered.
