Great Boulder Resources (ASX: GBR) has received “spectacular” assay results from the last two diamond holes drilled at Mulga Bill in April, as well as further assays from recent RC and AC drilling at Mulga Bill within the Side Well Gold Project near Meekatharra in Western Australia.
“This sensational result is in a shallower part of Mulga Bill, on the same section as our first high-grade intersection early last year,” Managing Director, Andrew Paterson, said.
“The intersection is within the upper part of the weathering profile below the base of gold depletion, so there is likely to be a component of supergene enrichment in the gold grade.
“The significance of this result is that it supports our geological interpretation in that area, which has changed significantly since the first holes were drilled. It is also significant that the hole intersected a thicker zone of very high-grade mineralisation compared to the narrower intersections reported in earlier diamond holes.
“RC drilling has been progressing well since the end of June, with holes completed at the southern end of the Mulga Bill trend as well as at Ironbark. We are now drilling continuously rather than on a campaign basis, which means we expect a steady flow of results throughout the rest of the year and into 2023.”
Highlights from the diamond drilling include:
• 5.9m @ 39.37g/t Au from 84.3m, including 3.6m @ 63.79g/t Au from 85.4m, with 0.3m of core loss from 85.1m in hole 22MBRC005
• 1m @ 12.25g/t Au from 224m in 22MBRC007
Highlights from recent air-core (AC) drilling include:
• 3m @ 4.32g/t Au from 47m in 22SWAC153 at Mulga Bill • 2m @ 1.07g/t Au from 93m in 22SWAC163 at Mulga Bill
• 3m @ 1.82g/t Au from 45m in 22SWAC174 at Loaded Dog
• 1m @ 8.51g/t Au from 60m in 22SWAC175 at Loaded Dog
• 4m @ 1.63g/t Au from 76m in 22SWAC180 at Loaded Dog
• 4m @ 1.16g/t Au from 72m in 22SWAC183 at Loaded Dog
21 AC holes remain to be reported, with results expected in the coming weeks. The AC results to date provide further encouragement within gaps in previous drill coverage along the 6km-long Mulga Bill footprint, with results such as 1m @ 8.51g/t Au in 22SWAC175 and 4m @ 1.16g/t Au in 22SWAC183 adding definition at Loaded Dog.
Meanwhile the result in hole 22SWAC180 (4m @ 1.63g/t Au) demonstrates potential for additional mineralisation further west, as this is the westernmost hole on that line.
RC drilling is currently making good progress at the southern end of the Mulga Bill corridor and at the nearby Ironbark prospect, with initial assays expected in August. Assay results from the 95-hole AC program completed at the Whiteheads Gold Project in June 2022 remain outstanding.
