TORONTO, ONTARIO–(Marketwired - Sept. 1, 2016) - Lundin Mining Corporation (TSX:LUN)(OMX:LUMI) (“Lundin Mining” or the “Company”) today reported its Mineral Resource and Reserve estimates as at June 30, 2016.
On a consolidated and attributable basis, contained metal in the Proven and Probable Mineral Reserve category totaled 3,931 kt of copper, 2,737 kt of zinc and 95 kt of nickel.
Commenting on the June 2016 Mineral Reserve and Resource estimates, Mr. Paul Conibear, President and CEO of Lundin Mining said, “We are pleased that our continued exploration at both Candelaria and Eagle have again resulted in success, with further increased Mineral Resources and Reserves at Candelaria and the exciting maiden Inferred Mineral Resource on Eagle East. Our significant investment in near mine targets continues to be successful in adding substantially to our Mineral Resource base.”
Conceptual level studies into growth opportunities at Candelaria continue to advance and are being supported by ongoing underground exploration success. Drilling continues at Eagle to define the limits of Eagle East and test for new targets. The June 2016 Mineral Resource and Reserve estimates at Neves Corvo and Zinkgruvan have largely replaced the depletion by mining despite reduced exploration spending.
Reserves and Resources Highlights
- Total Candelaria Measured and Indicated Mineral Resources have increased to 689.0 Mt at 0.64% Cu (from 643.6 Mt at 0.63% Cu in the July 2015). The increase reflects the success of ongoing underground exploration campaigns and conversion of underground Inferred Mineral Resources to Measured or Indicated.
- Total Candelaria Proven and Probable Mineral Reserves have increased by approximately 6% to 482.6 Mt at 0.54% Cu (from 455.2 Mt at 0.56% Cu reported as of June 30, 2015), despite depletion by mining over the last 12 months. The increased open pit Proven and Probable Mineral Reserves, excluding stockpiles, of 337.6 Mt at 0.54% Cu (from 314.6 Mt at 0.57% Cu in June 30, 2015) reflect further optimization of the open pit, exploration success and revised economic parameters.
- Total Candelaria underground Proven and Probable Mineral Reserves continue to show additions and now stand at 51.1 Mt at 0.90% Cu compared to the June 2015 total of 46.8 Mt at 0.97% Cu.
- At Eagle, an initial Eagle East Inferred Mineral Resource was reported on June 29, 2016 containing 1.2 Mt at 5.1% Ni and 4.3% Cu. Total Proven and Probable Mineral Reserves have reduced to 3.7 Mt at 2.5% Ni and 2.2% Cu due to mining depletion.
- Total copper Measured and Indicated Mineral Resources at Neves-Corvo have offset mining depletion to stand at 70.0 Mt with a grade of 2.7% Cu. A similar situation is evident with the zinc Measured and Indicated Mineral Resources, which remain at 106.8 Mt at 6.1% Zn.
- Copper Proven and Probable Mineral Reserves at Neves-Corvo increased to 26.1 Mt at 2.7% Cu from last year’s 25.9 Mt at 2.7% Cu despite mining depletion. Zinc Proven and Probable Mineral Reserves have decreased to 23.4 Mt at 7.2% Zn from 25.3 Mt at 7.1% Zn following an update to the cut-off grade.
- At Zinkgruvan, zinc in Measured and Indicated Mineral Resources and Proven and Probable Mineral Reserves have decreased slightly from 2015 due to mining depletion.
- As previously disclosed, Measured and Indicated Mineral Resources at Tenke Fungurume, dated December 31, 2015, increased to 680.3 Mt at 2.5% Cu and 0.3% Co, inclusive of 45.0 Mt of stockpiled material, reflecting successful ongoing exploration activity. Contained copper and cobalt metal in these Mineral Resources increased by 7.0% and 4.3% respectively over the prior year. Inferred Mineral Resources increased to 531.7 Mt from 392.2 Mt, reflecting further exploration success and inclusion of the first estimate on the Dipeta syncline.
- Proven and Probable Mineral Reserves at Tenke Fungurume increased to 144.4 Mt at 2.6% Cu and 0.4% Co from 136.1 Mt at 2.7% Cu and 0.4% Co, as a result of exploration success and updated open pit optimizations.

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 (“NI 43-101”), classified in accordance with Canadian Institute of Mining Metallurgy and Petroleum’s “CIM Standards on Mineral Resources and Reserves Definitions and Guidelines” (the “CIM Guidelines”). The definitions of Mineral Reserves and Mineral Resources are set out in our disclosure of our Mineral Reserve and Mineral Resource estimates in our Annual Information Form.
The Company uses the terms “Mineral Resources”, “Measured Mineral Resources”, “Indicated Mineral Resources” and “Inferred Mineral Resources”. While those terms are recognized by Canadian securities regulatory authorities, they are not recognized by the United States Securities and Exchange Commission the “SEC”) and the SEC does not permit U.S. companies to disclose resources in their filings with the SEC.
Pursuant to the CIM Guidelines, 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.
