A 2,000m diamond drilling is underway at Mulga Bill to confirm continuity of high-grade mineralisation before an induced polarisation geophysical survey begins later this week.  

At the same time, a geophysical team is mobilising to site to start an IP survey, also at Mulga Bill, part of the wider Side Well Gold Project in Western Australia.

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.

An aircore drilling program is also being carried out at Jones Well, north of Mulga Bill.

On the hunt for chargeable sulphides linked with gold

Great Boulder (ASX:GBR) managing director Andrew Paterson said this program should provide a “huge amount” of structural data for targeting reverse circulation (RC) drilling programs.

“The air-core rig is still testing targets up at Jones Well, with about 10 days left on that program,” he said.

“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.

“Lastly, 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 the backlog of samples from 2021 has been cleared, the company expects a much more consistent and timely flow of assays through the remainder of this year
