Great Boulder Resources Ltd (ASX:GBR) has progressed exploration activity at the Side Well Gold Project in Western Australia.
First item on the agenda is diamond drilling at Mulga Bill, with about 2,000 metres of drilling planned along the mineralised corridor.
The drilling will test the orientation and continuity of structures hosting high-grade gold mineralisation and is expected to take three to four weeks.
“It’s great to have a diamond rig on site,” managing director Andrew Paterson said. “This program should provide a huge amount of structural data which we’ll be able to use for targeting RC programs going forward.
“The aircore rig is still testing targets up at Jones Well, with about 10 days left on that program.
“We are also looking forward to seeing the results from the IP survey, because if we can see chargeable sulphides associated with gold, we can extrapolate that to other targets nearby.”

Survey along strike
Later this week a geophysical team will arrive on site to commence an induced polarisation (IP) survey over Mulga Bill.
Data will be acquired on east-west lines to test the chargeable response of sulphide minerals associated with known high-grade gold mineralisation in the central section of Mulga Bill.
If the technique proves successful the team will complete additional lines along strike, as well as a 3D-IP survey on a north-south orientation along the strike of the deposit.
A maiden aircore campaign is also currently underway at Jones Well, north of Mulga Bill.
Assay backlog starting to clear
While assay turnaround time has been dramatically reduced for 2022 drilling, the company is still waiting on a large backlog of reverse circulation (RC) and aircore samples from the 2021 campaign.
“I’m very pleased to note that changing assay labs has reduced our sample turnaround time to around four to six weeks for drilling programs this year,” Paterson said.
“Once we’ve cleared the backlog of samples from 2021 we expect a much more consistent and timely flow of assays through the remainder of this year.”
