Great Boulder Resources Ltd (ASX:GBR) has struck more high-grade gold during its maiden reverse circulation (RC) drill campaign at the Ironbark prospect, part of the Side Well Gold Project in WA.
The precious metal explorer intersected 9 metres at 4.49 g/t gold from 104 metres and 20 metres at 3.05 g/t from 120 metres during the latest round of RC drilling.
Thanks to the findings, gold is now defined over 400 metres at Ironbark and remains open along strike and at depth.
What’s more, new gold and copper hits from the nearby Mulga Bill prospect complemented the Ironbark results, including.
- 4 metres at 7.02 g/t gold from 84 metres and 5 metres at 8.67 g/t from 114 metres; and
- 25 metres at 1.34% copper, 13.33 g/t silver and 0.41 g/t gold from 88 metres, including 13 metres at 2.01% copper, 18.59 g/t silver and 0.36 g/t gold from 88 metres.
GBR has since completed aircore drilling at the Whiteheads Project near Kalgoorlie, while further RC drilling should recommence shortly at the Side Well Project.
The story unfolds
Commenting on the progress to date, Great Boulder managing director Andrew Paterson said there was more work to do to unlock Side Well’s mineralised potential.
“At Ironbark, hole 22IBRC003 returned two strong intersections along strike from the earlier result in hole 007 which intersected 14 metres at 4.25 g/t gold.
“More drilling is now required in the central area of Ironbark to test continuity between this zone and another high-grade result of 22 metres at 2.47 g/t in hole 005 to the north.
“Based on these results, it appears the northern-most hole was drilled too far west to intersect the trend, in which case Ironbark is still open along strike in both directions.
“Results are still coming in for the recent RC drilling at Mulga Bill. High-grade gold intersections in hole 22MBRC012 plus our highest-grade copper intersection in hole 22MBRC003 demonstrate the potential of the system.
“We’re very keen to start RC testing the southern targets at Mulga Bill at the end of June.
“With the rig back on site for the rest of the year, we will have a steady flow of results coming through and I’m sure there will be plenty more excitement as the story unfolds.”
Next on the agenda
When RC drilling resumes at the end of June, Great Boulder will focus on new targets at the southern end of the Mulga Bill-Loaded Dog corridor.
Here, a recent aircore hole ended in 23.78 g/t gold after drilling 150 metres deep.
An extensional and infill RC program is also planned for the Ironbark prospect, where the current drill coverage includes just seven holes along 400 metres of strike.
Subsequently, the next round of drilling will test the continuity of mineralisation between the current intersections, check for strike extensions to the north and south and also suss out deeper targets beneath known intersections.
In the meantime, the 57 aircore holes now under the microscope include infill drilling over substantial gaps in coverage north and south of Loaded Dog, some of which test the target area immediately east of an IP chargeability anomaly.
GBR believes end-of-hole gold and multi-element assays from these holes are essential for planning more RC drill campaigns in the coming months.
