  • Great Boulder Resources (GBR) has reported a mixed bag of results from recent drilling activity at its joint venture Winchester copper-nickel project
  • Four holes were drilled at the project near Laverton in the Western Australian outback, but only one hole showed promising results, which extended sulphide mineralisation down plunge
  • The diamond hole intersected nearly four and a half metres at 0.8 per cent copper, 4.7 grams per tonne of silver, 0.08 per cent nickel and 0.01 per cent of cobalt from nearly 202 metres in the main sulphide shoot
  • GBR says mineralisation is open to the west and at depth, which the company will continue to explore later in the year when it's allowed back to the site which is closed due to COVID-19 restrictions
  • Great Boulder is down 3.3 per cent today selling shares for 2.9 cents each

Metals explorer Great Boulder Resources (GBR) has reported a mixed bag of results from recent drilling activity at its joint venture Winchester copper-nickel project.

The company drilled four holes at the project near Laverton in remote Western Australia, but only one showed promising results which extended sulphide mineralisation down plunge.

Diamond hole 20WNRCD002 intersected nearly four and a half metres at 0.8 per cent copper, 4.7 grams per tonne of silver, 0.08 per cent nickel and 0.01 per cent of cobalt from nearly 202 metres in the main sulphide shoot.

The company says the mineralisation sits about 250 metres down-plunge from the interpreted top of the shoot, or 80 metres down-plunge from the nearest drill hole, and mineralisation remains open to the west and at depth.

“The chemistry is changing slightly at depth, with a reduction in nickel content and a sharp up-tick in silver values. We need to do more work to understand these differences in nickel and copper distribution."

Managing Director, Andrew Paterson

GBR says it will head back to the site to resume drilling later in the year, once COVID-19 restrictions have been lifted, which currently means access to areas in and around remote aboriginal communities is limited.

Great Boulder is down 3.3 per cent today selling shares for 2.9 cents each at 1:15 pm AEST.
