Toronto, OntarioJanuary 6, 2020 – Doré Copper Mining Corp. (the “Corporation” or “Doré Copper“) (TSXV: DCMC) is pleased to announce its initial drilling plans for 2020. Doré Copper owns mineral rights and has options to various deposits in the Chibougamau mining camp in Québec. The initial drilling plans will aim to expand the estimated resources at Corner Bay and Cedar Bay and test the potential high-grade gold zone at the optioned Joe Mann property. Drilling will commence in the second week of January 2020. 


  • Corner Bay remains open in all directions and drilling will focus on extending mineralization to the south where 2018 drilling intersected wide zones of high-grade copper including 3.45% Cu over 13.3 m and 4.11% Cu over 6.6 m.
  • Cedar Bay drilling will focus on extending the high-grade 10-20 zone where drilling in 2018 intersected 2.4 m of 1.7% Cu and 19.5 g/t Au and 2.4 m of 4.54% Cu and 15.4 g/t Au, and testing the Cedar Bay main vein at depth.  
  • The high-grade Joe Mann gold mine will be tested along strike and down dip from previously mined zones to follow up on holes drilled in 2008 after the mine closure that intercepted 30.3 g/t and 1.3% Cu over 3.02 m and 26.6 g/t Au over 1.8 m.

Ernest Mast, President and CEO of Doré Copper stated, “The initial 2020 drilling program will help us determine the immediate expansion potential of our known deposits at Corner Bay and Cedar Bay and drill for the first time since 2008 the down dip potential of Joe Mann. The Corporation is uniquely positioned to extend known mineral resources of both high-grade copper and gold deposits all in close vicinity to the Corporation’s centrally located 2,700-tpd mill.” 

Corner Bay

Drilling at Corner Bay will focus on extending the main zone to the south along strike where drilling in 2018 identified wide zones of  high-grade copper including CB-18-07:  3.45% Cu over 13.3 m, CB-18-06: 2.33% Cu over 12.3 m and CB-18-05: 4.11% Cu over 6.6 m. The Corporation is planning to drill six holes testing the mineralization on strike and down dip with the potential to extend mineralization to the south.

Cedar Bay

The Corporation will recommence drilling at Cedar Bay where the goal will be to extend the resources at the 10-20 zone where 2018 drilling confirmed a high-grade zone of stacked veins, including CDR 18-02: 2.4 m of 1.7% Cu and 19.5 g/t Au and CDR 18-03: 2.4 m of 4.54% Cu and 15.4 g/t Au. The drilling will also target the Cedar Bay main zone at depth which is 200 meters to the south-west of the 10-20 zone. Cedar Bay produced 3.8 Mt at 1.57% Cu and 3.12 g/t Au to a depth of 675 meters. The mineralization remains open at the level of the shaft, 1,100 m, with limited drilling conducted to test the depth potential of the parallel mineralized veins.

Two initial holes will be drilled after which the Corporation will utilize directional drilling technology to drill four to six additional holes reducing the overall cost of drilling and maximizing the number of intercepts.

Joe Mann

Thirdly, the high-grade Joe Mann gold mine will be tested along strike and down dip following up on holes EE-188: 30.3 g/t and 1.3% Cu over 3.02 m and EE 189B: 26.6 g/t Au over 1.8 m, and 14.72 g/t Au over 1.2 m. These two high-grade drill intercepts were drilled in 2008, after the mine stopped operations. No follow-up work has ever been done on EE-188 and EE-189B. A total of two to three pierce points will be obtained at Joe Mann prior to deciding on future drilling.

The Corporation will use Miiken Drilling as the drilling contractor. Miiken is a joint venture between Chibougamau Diamond Drilling Ltd., the First Nations community of Ouje-Bougoumou and the First Nations community of Mistissini both located in the Eeyou Istchee territory.
