Lundin Mining Corporation (CNW Group/Lundin Mining Corporation)

TORONTO, Sept. 5, 2019 /CNW/ - (TSX: LUN; Nasdaq Stockholm: LUMI) Lundin Mining Corporation ("Lundin Mining" or the "Company") today reported its Mineral Resource and Reserve estimates as at June 30, 2019.

On a consolidated and attributable basis, estimated contained metal in the Proven and Probable Mineral Reserve categories totalled 5,507 kt of copper, 3,231 kt of zinc, 108 kt of nickel, 977 kt of lead and 6.8 Moz of gold.

Commenting on the June 2019 Mineral Resource and Reserve estimates, Marie Inkster, President and CEO said, "Our exploration teams continue to deliver considerable value as is demonstrated by meaningful increases in the Mineral Resources and Reserves with this update. The acquisition of Chapada coupled with ongoing exploration success, particularly at Candelaria, has increased our total contained copper metal in Mineral Reserves by over 1,800 kt or 50% from our June 2018 estimates.

Increases in Mineral Reserves in the Candelaria underground mines and Española open pit will underpin improvements to the copper production profile and support ongoing underground expansion studies. At Chapada, increased Mineral Reserves in the Sucupira and Baru NE deposits further our belief that the area has significant exploration potential which will support mine expansion studies.

Delineation and extension drilling have been highly successful at Eagle East. This has resulted in an additional year of mine life at Eagle. At Zinkgruvan, exploration success in Dalby has resulted in a significant increase in the Indicated and Inferred Mineral Resource estimates, supporting mining studies currently underway."

2019 Mineral Resources and Reserves Highlights

  • Total estimated Candelaria Measured and Indicated Mineral Resources have increased by approximately 5% to 998.6 Mt at 0.65% copper (from 952.5 Mt at 0.65% copper reported as of June 30, 2018). This increase reflects the continued success of the exploration campaigns in the underground mines and the delineation drilling of the Española surface deposit which now contains an estimated Measured and Indicated Mineral Resource of 73.1 Mt at 0.40% copper.

  • Total estimated Candelaria Proven and Probable Mineral Reserves have also increased by approximately 5% to 663.7 Mt at 0.54% copper (from 634.0 Mt at 0.54% copper reported as of June 30, 2018).

  • Total estimated Candelaria open pit Proven and Probable Mineral Reserves, excluding stockpiles, have increased modestly and are now 386.8 Mt at 0.49% copper (from 383.7 Mt at 0.49% copper reported as of June 30, 2018) reflecting additional drill information and revised pushback plans, offset by 12 months of mining depletion.

  • Proven and Probable Mineral Reserves on the Española deposit have increased by 76% to 55.8 Mt at 0.41% copper (from 31.7 Mt at 0.42% copper reported as of June 30, 2018) as a result of delineation drilling. Subject to permitting, surface waste stripping on Española is targeted to commence in 2024 with ore forecast to be delivered to the plant in 2026.

  • Total estimated Candelaria Underground Proven and Probable Mineral Reserves now stand at 148.2 Mt at 0.85% copper. This is an increase of approximately 11% or 14.2 Mt over last year's estimate reflecting continued exploration success, particularly in the Candelaria North Sector. Future expansion studies for the combined Candelaria underground mine sectors are underway.

  • Total Chapada copper-gold Measured and Indicated Mineral Resources, inclusive of Mineral Reserves, are estimated at 1,090.8 Mt at 0.24% copper and 0.15g/t gold. An updated Technical Report on Chapada is expected to be published in early October 2019.

  • Total Chapada Proven and Probable Mineral Reserves are estimated at 738.8 Mt at 0.24% copper and 0.15g/t gold. New Mineral Reserves, derived from ongoing exploration drilling, have been added in both the Sucupira and Baru NE deposits resulting in an increase over those Mineral Reserves estimated at December 2018.

  • The total combined estimated Eagle and Eagle East Proven and Probable Mineral Reserves remain virtually unchanged from last year at 4.1 Mt at 2.6% nickel and 2.2% copper with mining depletion at Eagle offset by significant discovery from infill and extension drilling at Eagle East. The Eagle East Probable Mineral Reserve estimate has increased to 2.3 Mt at 3.2% nickel and 2.6% copper. The Eagle mine life is now extended to at least 2025.

  • Estimated copper and zinc Measured and Indicated Mineral Resources at Neves-Corvo are 61.7 Mt at 2.3% copper and 71.4 Mt at 6.9% zinc respectively. Copper Mineral Resources are broadly unchanged from those estimated at June 30, 2018 whereas the zinc Mineral Resources have decreased with the adoption of a higher zinc cut-off grade. Please see the "Notes on Mineral Resource and Reserve Tables" in this news release.

  • Copper Proven and Probable Mineral Reserve estimates at Neves-Corvo decreased slightly to 27.9 Mt at 2.2% copper from last year's 30.3 Mt at 2.3% copper largely as a result of mining depletion. Zinc Proven and Probable Mineral Reserve estimates have remained largely unchanged from last year at 29.7 Mt at 7.5% zinc with infill drilling offsetting mining depletion.

  • At Zinkgruvan, continued drilling in the Dalby area has generated additional Indicated and Inferred Mineral Resources. Total estimated zinc Measured and Indicated Mineral Resources now stand at 20.2 Mt at 8.1% zinc and 3.3% lead and Inferred Mineral Resources at 19.8 Mt at 7.0% zinc and 3.3% lead. Exploration drilling from surface and infill from underground continues on Dalby with conceptual feasibility and mine design work ongoing.

  • Zinkgruvan estimated zinc Proven and Probable Mineral Reserves have increased to 10.8 Mt at 7.4% zinc and 3.4% lead while estimated copper Proven and Probable Mineral Reserves are now 2.7 Mt at 2.0% copper.

The table attached to this news release summarizes the Mineral Resource and Mineral Reserve estimates for each of the Company's mines as of June 30, 2019.

Notes on Mineral Resource and Mineral Reserve Tables

Mineral Resources and Mineral Reserve estimates are shown on a 100% basis for each mine. The Measured and Indicated Mineral Resource estimates are inclusive of those Mineral Resource estimates modified to produce the Mineral Reserve estimates. All estimates are prepared as at June 30, 2019.

Estimates for all operations are prepared by or under the supervision of and verified by a Qualified Person as defined in NI 43-101 or have been audited and verified by independent Qualified Persons on behalf of Lundin Mining. The technical information in this news release has been prepared in accordance NI 43-101 and has been reviewed and verified by Stephen Gatley, BSc (Eng), C.Eng. Vice President - Technical Services of the Company, who is a "Qualified Person" under NI 43-101.

Candelaria and Ojos

Mineral Resources at Candelaria are estimated using metal prices of US$3.16/lb copper and US$1,000/oz gold and an exchange rate of USD/CLP 600. Mineral Reserves were estimated using metal prices of US$2.75/lb copper and US$900/oz gold and an exchange rate of USD/CLP 600.

Candelaria and La Española open pit Mineral Resource estimates are reported within a conceptual pit shell with cut-off grades of 0.15% and 0.20% copper respectively. Underground Mineral Resources are estimated at a cut-off grade of 0.55% copper. Mineral Reserves for the Candelaria open pit, Española open pit and underground for the Candelaria property are estimated at cut-off grades of 0.17%, 0.20% and 0.57% copper, respectively. Underground Mineral Reserves for the Ojos del Salado property (Santos and Alcaparrosa mines) are both estimated at cut-off grades of 0.63% copper. Patricio Calderón, Superintendent Exploration, Patricio Vega, Open Pit Mine Engineer and Cristian Erazo, Underground Mine Engineer, each of whom is a Registered Member, Chilean Mining Commission, employed by the Candelaria mining complex and is a Qualified Person as defined under NI 43-101, supervised the preparation of and verified the Mineral Resource estimate, open pit Mineral Reserve and underground Mineral Reserve estimates respectively, and the scientific and technical information on Candelaria contained in this news release.

For further information, refer to the Technical Report entitled Technical Report for the Candelaria Copper Mining Complex, Atacama Province, Region III, Chile dated November 28, 2018, which is available on the Company's SEDAR profile at www.sedar.com.

Chapada

Mineral Resources at Chapada and Suruca SW copper-gold are estimated using metal prices of US$4.00/lb copper and US$1,600/oz gold and an exchange rate of USD/BRL 3.95.
