Great Boulder Resources Ltd (ASX:GBR) has generated strong gold results from first-pass aircore drilling designed to test pathfinder elements at Mulga Bill North, striking mineralisation 500 metres north of the current resource area at the Side Well Gold Project in Western Australia.
One of the standout results was 12 metres at 2.61 g/t gold from 88 metres of depth, which included 4 metres at 4.27 g/t from 93 metres with another hole returning 4 metres at 5.03 g/t from 84 metres and 3 metres at 2.31 g/t from 112 metres.
Given very little exploration has been completed at Mulga Bill North, the results will guide GBR in the next round of drilling at the prospect.
Highly encouraging early results
“We use aircore drilling to identify pathfinder elements and gold anomalism, so intersecting high-grade mineralisation is always a great result,” Great Boulder Resources managing director Andrew Paterson said.
“These results sit between 500 metres and 800 metres north of the 568,000-ounce gold Mulga Bill mineral resource.
“There is very little effective drilling between this area and the high-grade drill results we announced last month from drilling further south, which highlights the scale and potential of the Mulga Bill North area.
“We’re starting to see west-dipping high-grade veins, including the result in 24SWAC214 which hit 12 metres at 2.61 g/t gold from 88 metres, and we will be looking to extend these with further drilling.”
Other results of note from this latest round of drilling include:
- 3 metres at 2.68 g/t gold from 114 metres; and
- 9 metres at 1.95 g/t from 100 metres.
Potential for further mineralisation
“Another outcome from this program is the identification of a dacitic unit on the eastern margin of the drilling,” Paterson continued.
“This is significant because dacitic volcaniclastics host the high-grade mineralisation at Mulga Bill, suggesting we should extend our drilling further east.
“Meanwhile we have assays pending on 45 aircore holes from Polelle, which is the first drilling we’ve completed there, and we’ll be drilling again soon at Saltbush and Mulga Bill North.”
GBR expects to resume drilling at Side Well by mid-July, with the first program to test a high-priority, 2-kilometre-long geochemical anomaly northwest of the Saltbush Prospect.
