Visible gold has been observed in diamond core from drilling at the Mulga Bill prospect within Great Boulder’s Side Well gold project in Western Australia.

Disseminated occurrences of visible gold were noted at a depth of about 130m down-hole in hole 22MBDD002 within a 3.1m-wide quartz vein.

The hole was collared 125m west of reverse circulation hole 21MBRC034 that intersected a 6m zone grading 24.33 grams per tonne (g/t) gold from a depth of 132m, leading Great Boulder Resources (ASX:GBR) to conclude that the same quartz zone is present in both holes.

Visible gold is always welcome especially when it comes on the back of high-grade intersections, positive metallurgical testing and indications that only a small portion of the Mulga Bill prospect has been tested to date.

“It’s always exciting to see visible gold in core, emphasising the high tenor of mineralisation in these veins,” managing director Andrew Paterson said.

“The team will finish sampling this hole and submit it for assay as soon as possible.

“RC drilling recommences next week, and we are excited to test the new high-grade target identified at the southern end of Mulga Bill where we announced an intersection of 23.78g/t Au earlier this year.”

Forward program

Diamond drilling at Mulga Bill has been temporarily stopped due to bad weather, with seven holes totalling 1,675m drilled to date.

The rig has moved to another job in the area and is expected to return to complete the last hole in a few weeks.

Meanwhile, 3D induced polarisation work at Mulga Bill is expected to be completed this week following minor delays due to thunderstorm activity and associated lightning interfering with electrical readings.

RC drilling totalling about 5,000m is due to recommence next week with Paterson noting that the company expects continuous drilling at Mulga Bill once it collates the diamond data into its drill planning model.

The company previously noted that it has budgeted about 100,000m of drilling for 2022.
