THE DRILL SERGEANT: Great Boulder Resources (ASX: GBR) reported on recent exploration activity undertaken at the company’s Side Well gold project in Western Australia.
Great boulder Resources completed a high-resolution gravity survey combined with reprocessing of previous VTEM data, the results from which it has interpreted to demonstrate the scale of the Mulga Bill mineralised corridor, particularly a three kilometres-long section where coincident gravity and conductive features present a high-priority exploration target extending to depth.
In parallel to this, the company also received assays from diamond core and a single RC scissor hole that have confirmed the orientation of high-grade quartz veins such as that recently intersected in hole 21MBRC034 of 14 metres at 36.12 grams per tonne gold from 91m, including 3m at 149.89g/t gold.
“This is a significant development in our understanding of Mulga Bill.” Great Boulder Resources managing director Andrew Paterson said in the company’s ASX announcement.
“The geophysical interpretation has sharpened our focus on the three kilometres between the two Proterozoic dykes.
“So far, we’ve only drilled the first 900 metres of strike in this area with extremely high-grade gold intersections.
“Our new model suggests the most prospective area is further south, where we have gold and bismuth pathfinders in AC drilling but we haven’t yet tested it with any RC drilling.
“If we have a tabular subvertical zone over three kilometres long and 50 metres wide, open at both ends with strong copper-gold-silver enrichment and a stacked set of high-grade quartz-pyrite-gold veins, this deposit has potential for a very significant metal endowment.”
Upcoming work at the Side Well project is to include phase 5 RC drilling that is currently progressing and scheduled to be complete in the next two to three weeks.
During this program the company intends testing a deeper priority target as well as some initial test holes into the new Ironbark and Loaded Dog prospects.
The next phase of AC drilling is also now underway testing a range of targets on the Mulga Bill corridor as well as regional targets within the Side Well gold project.
