THE DRILL SERGEANT: Great Boulder Resources (ASX: GBR) announced results from a maiden reverse circulation (RC) drilling program carried out in November 2020 at the Blue Poles Prospect, situated within the company’s Whiteheads project north of Kalgoorlie in Western Australia.
Great Boulder Resources declared the drilling had confirmed the discovery of new gold mineralisation at Blue Poles.
Fifteen RC holes were drilled for a total of 1,448m to test primary gold mineralisation beneath air-core (AC) drilling intersections.
The program identified primary mineralisation over a 700 metres strike length, including broad zones of up to:
52 metres at 1.02 grams per tonne gold from 28m to the end of hole.
Lower grade intersections were also encountered over considerable widths including:
28m at 0.61g/t gold from 32m;
29m at 0.66g/t gold from 68m; and
42m at 0.45g/t gold from 28m.
“This is an exciting development at Blue Poles,” Great Boulder Resources managing director Andrew Paterson said in the company’s ASX announcement.
“There are two key takeaways here: firstly, we’ve identified primary gold over a 700 metres length in our first few RC holes, and it remains open at depth and to the south.
“That means the deposit is in-situ and not just a shallow supergene deposit limited to the weathered, near-surface material.
“Secondly, these intersections up to 52 metres wide demonstrate the potential for a large mineralised system.
“The next round of drilling will test the true thickness of these zones.
“These initial holes are on lines 100 metres apart, so the discovery remains at a very early stage.”
Great Boulder is already planning a second round of RC drilling to define and extend these results.
This will commence following the completion of gravity survey processing and target planning.
