Great Boulder Resources (ASX: GBR) has drilled a “spectacular” intersection of 15m @ 35.82g/t Au from 88m in new drilling results from the Side Well Gold Project near Meekatharra in Western Australia.
RC drilling into the high-grade vein area at the northern end of Mulga Bill intersected
• 15m @ 35.82g/t Au from 88m, including 6m @ 83.58g/t Au from 96m in hole 22MBRC038.
This structure also hosts previous intersections of 5.9m @ 39.37g/t Au from 84.3m (22MBDD005, announced 7/7/22) and 6m @ 24.33g/t Au from 132m (21MBRC034, announced 2/9/21).
“This spectacular result is the highest-grade intersection and the highest individual gold assay drilled to date at Side Well,” Managing Director, Andrew Paterson, said.
“It’s interpreted to be close to true width, so it’s among the widest intersections of +25g/t Au in drilling we’ve yet seen.
“It demonstrates that we’ve not yet closed off this high-grade vein area, which sits in the northern end of Mulga Bill containing many of the highest-grade intersections in the project. This area has been the focus of recent drilling in our Phase 3 and 4 RC campaigns this year.
“The new result will be used to fine-tune the 3D vein model and target more drilling in the near future.
“Meanwhile we’re making good progress with the third phase of RC drilling at Ironbark as we attempt to define the extent of mineralisation to the north and south and advance the prospect towards an initial Mineral Resource Estimate.”
The company has received assay results for all holes drilled in the recent RC programs at Flagpole and Loaded Dog. In addition to these results the company has received initial assays for 13 of 19 RC holes drilled during Mulga Bill Phase 3, and five of 23 holes in Mulga Bill Phase 4.
Highlights include:
• 15m @ 35.82g/t Au from 88m including 6m @ 83.58g/t Au from 92m in 22MBRC038 at Mulga Bill. This includes 4.0m composite samples to 96m down-hole.
• 6.0m @ 5.52g/t Au from 80m including 4.0m @ 7.99g/t Au from 80m in the same vein in 22MBRC039 at Mulga Bill. This intersection approximately 25m north of 22MBRC038 extends high-grade vein-related mineralisation upwards into the deleted zone.
• 2.0m @ 52.00g/t Au from 128m in 22MBRC030 in the Eastern Zone at Mulga Bill.
The high-grade vein (HGV) area in the north of the Mulga Bill is interpreted to contain a series of vein sets that sit within more felsic units of the stratigraphy. These north-south trending stratigraphic units have a width of between 50-100m and veins are developed either as flat-lying sets or west-dipping sets along with vertical mineralisation zones on lithological boundaries.
The main HGV defined to date has a strike length of more than 130m with the new intersection from 22MBRC038 lying at the southernmost boundary of current modelling. The intersection in hole 22MBRC038 extends the high-grade vein further south by approximately 30 metres from previous drilling.
This structure also contains previous high-grade intersections such as 5.9m @ 39.37g/t Au and 6m @ 24.33g/t Au, the latter of which is in the same hole as the project’s highest-grade result: 14m @ 36.12g/t Au from 91m. The 22MBRC038 intersection sits within a moderately weathered quartz zone. There is potential supergene enrichment to contribute to the extremely high grades in the area.
