First drilling program to target high-grade extensions

Toronto, Ontario July 30, 2020 – Doré Copper Mining Corp. (the “Company” or “Doré Copper“) (TSXV: DCMC) is pleased to announce that it has received the permit associated with the drilling of the Joe Mann property in Québec, Canada. The Joe Mann property is part of the option agreement announced by the Company on January 2, 2020. The Company has also advised local stakeholders of its drilling plans at Joe Mann. Drilling will commence in approximately two weeks once the current drilling program at Doré Copper’s Cedar Bay property is completed. 

“We are excited to focus on our high priority exploration targets at this high-grade gold underground asset that remains open at depth and along strike, given market fundamentals that have strengthened gold prices to record-setting highs,” commented Ernest Mast, President and CEO of Doré Copper.

The two drill rigs will follow up on holes EE-188 and EE-189B that were drilled in 2008 after the mine had ceased operations. Hole EE-188 intersected 3.02 meters grading 30.3 grams per tonne (g/t) gold (Au) and 1.30% copper (Cu). Hole EE-189B intersected 1.88 meters grading 26.66 g/t Au and 0.40% Cu. The intersections are 150 meters apart and approximately 170 meters beneath the lowest mining level in the mine. No prior drilling has occurred to follow up on the high-grade extensions. A long section view of the area that will be drilled is shown below. 

The Joe Mann Gold Mine was one of the highest-grade gold mines in Canada and produced 1.17 million ounces of gold grading 8.26 g/t between 1956 and 2007. The mine is located approximately 60 kilometers from the Company’s Copper Rand mill, where ore from Joe Mann was processed from 2004 until its closure in 2007, and is accessible by all season roads.

Highlights of the Joe Mann Gold Mine:

  • Production of 1.173 million ounces of gold at a grade of 8.26 g/t Au, 607,000 ounces of silver at 5 g/t Ag and 28.7 million pounds of copper at 0.25% Cu (Source: Technical Report on the Joe Mann Mining Property dated January 11, 2016, prepared by Geologica Inc.).
  • Mineralization remains strong and persistent at depth with hole EE-189B intersecting 26.66 g/t Au over 1.8 meters and hole EE-188 intersecting 30.3 g/t Au and 1.3% Cu over 3.02 meters, extending the Main Zone 170 meters down dip.
  • The more recently discovered West Zone, a potential structural off-set remains open and is a high priority future exploration target with historical intercepts including 2.44 meters at 24.62 g/t Au, 3.93 meters at 31.54 g/t Au, 2.62 meters at 24.28 g/t Au and 3.2 meters at 16.1 g/t Au.
  • Exploration potential remains excellent including new parallel zones identified by recent surface prospecting work that lie just several hundred meters to the south of the main mine.
  • Well-developed infrastructure in place including year-round road access, administration office, power and a shaft down to the 1,145-meter level.

The Company plans to drill two holes in close proximity to the historical holes, with a minimum of one wedge per hole. The drill collars will be located on the adjacent property, also named Joe Mann, a joint venture between Jessie Resources (65%) (optioned by Doré Copper) and SOQUEM (35%). The holes will cross an untested area of the Rohault Zone which is part of the 65/35 joint venture. The closest intersection to those planned on Rohault comes from hole H-156 which intersected 0.67 meters at 11.0 g/t Au. SOQUEM will contribute 35% of the field costs of the joint venture. A plan view of Joe Mann’s planned drill holes and infrastructure is presented below.
