Great Boulder Resources Ltd (ASX:GBR) has observed visible gold in diamond core from Mulga Bill prospect at the Side Well Gold Project in Western Australia.
Disseminated occurrences of visible gold were noted at a depth of around 130 metres down-hole in diamond hole 22MBDD002, within a 3.1-metre-wide quartz vein.
Visible gold can be seen in both sides of the core.
The hole was collared 125 metres west of a reverse circulation (RC) drill hole 21MBRC034, which intersected 6 metres at 24.33 g/t gold from 132 metres.
This hole is now being sampled and submitted for assay, and the company expects that the quartz vein in 22MBDD002 is likely to be the same as that in 21MBRC034.
Although 22MBDD002 and 21MBRC034 were collared 125 metres apart, the two holes are drilled towards each other at a dip of -60°, meaning that 22MBDD002 has been drilled towards the east while 21MBRC034 was drilled towards the west.
Great Boulder managing director Andrew Paterson commented: “The intention of this hole was to confirm the orientation of high-grade veins in this area.
“It’s always exciting to see visible gold in core, emphasising the high tenor of mineralisation in these veins.
“The team will finish sampling this hole and submit it for assay as soon as possible.”
Bad weather stops diamond drilling
GBR has temporarily halted the diamond drilling program at Mulga Bill due to bad weather, with seven holes drilled for 1,675 metres of core.
The diamond rig has moved to another job in the area but is expected to return to Side Well to complete the last hole in this program in a few weeks.
A planned 3D Induced Polarisation (3D IP) survey at Mulga Bill has also experienced minor delays due to thunderstorm activity and associated lightning interfering with electrical readings. It is now expected to be completed this week.
Next steps
Plans and sections of the diamond holes will be announced once assaying is complete.
“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 23.78 g/t gold earlier this year,” said Paterson.
“This next phase of RC drilling will be a 5,000-metre program, and we anticipate continuous drilling programs at Mulga Bill as soon as we’ve collated the diamond data into our drill planning model.”
