Great Boulder is uncovering high grade gold all over the joint at Mulga Bill

Great Boulder Resources has released assay results from the last two diamond holes drilled at the Mulga Bill gold discovery – and they are spectacular.
The ~6km long Mulga Bill is part of the Side Well gold project in WA, which is Great Boulder’s (ASX:GBR) core focus.
The highlight hit was 5.9m at 39.37g/t gold from 84.3m (including 3.6m at 63.79g/t from 85.4m) in hole 22MBRC005.
The result confirms that high grade gold continues down dip from the original GBR “discovery hole”, which pulled up 3m @ 34.54g/t from 32m.
This sensational result is in a shallower part of Mulga Bill, GBR managing director Andrew Paterson says.
“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,” he says.
“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.”
21 AC holes from Mulga Bill remain to be reported, with results expected in the coming weeks, GBR says.
“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 [the nearby prospect] Loaded Dog,” the company says.
Meanwhile, the result in hole 22SWAC180 (4m @ 1.63g/t Au) demonstrates potential for additional mineralisation further west.
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 near Kalgoorlie remain outstanding.
“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,” Paterson says.
“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.”
