Great Boulder says new gold hits are all the go, way up in Ironbark

Mineralisation at Great Boulder’s Ironbark prospect appears to remain open along both strike directions after drilling returned more strong gold intersections.
Hole 22IBRC003 returned results of 9m at 4.49 grams per tonne (g/t) gold from a down-hole depth of 104m and 20m at 3.05g/t gold from 120m along strike from the earlier Hole 007 which struck 14m at 4.25g/t gold.
This has some intriguing implications for Great Boulder Resources (ASX:GBR) with managing director Andrew Paterson noting that more drilling is now required in Ironbark’s central area, to test continuity between this zone and another high-grade result of 22m at 2.47g/t gold in Hole 005 to the north.
“Based on these results it appears the northernmost hole 22IBRC006 was drilled too far west to intersect the trend, in which case Ironbark is still open along strike in both directions,” he adds.
22IBRC006 had failed to intersect any significant mineralisation, though the other two RC holes reported together with it earlier this month both returned high-grade intersections within broad gold intervals.
RC drilling at the Mulga Bill prospect, which along with Ironbark is part of the Side Well project near Meekatharra, Western Australia, has also returned high-grade gold and significant copper.
Notable gold results include 4m at 7.02g/t gold from 84m and 5m at 8.67g/t gold from 114m in 22MBRC012 while results such as 25m at 1.34% copper, 13.33g/t silver and 0.41g/t gold from 88m in 22MBRC003 adds potential to the sulphide zone.
“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,” Paterson adds.
“We’re very keen to start RC testing the southern targets at Mulga Bill at the end of June,” he says. “With the rig back onsite 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.”
Besides drilling at Mulga Bill, the company will also complete an extensional and infill RC program at Ironbark, which remains sparsely covered with just seven RC holes spanning 400m of strike drilled to date.
The next round of drilling will test continuity of mineralisation between the current intersections, test for strike extensions to the north and south, and also test deeper targets beneath known intersections.
Assays are also pending for 57 aircore holes that include infill drilling over significant gaps in coverage north and south of Loaded Dog and some holes which tested the target area immediately east of the IP chargeability anomaly recently tested by diamond hole 21MBRCD096.
End-of-hole gold and multi-element assays from these aircore holes will be essential to planning further RC drill campaigns in the area over the coming months.
