Great Boulder Resources Ltd (ASX:GBR) has hit upon high-grade gold intersections at Saltbush prospect within the Side Well Gold Project near Meekatharra, Western Australia.
The recent drilling campaign included aircore and reverse circulation (RC) drilling and yielded such intersections as 4 metres at 5.96 g/t gold from 9 metres, and 3 metres at 6.96 g/t from 91 metres, with one metre at 16.25 g/t.
These drill results extend the known high-grade mineralisation over a strike length of 300 metres.
Defining high-grade gold
“Saltbush is continuing to grow and after only a small number of holes in two phases of drilling we have defined high-grade gold over 300 metres of strike,” managing director Andrew Paterson said.
“We have sufficient confidence in this prospect to say it’s the first discovery in all our new targets along the Ironbark Corridor.
“Saltbush appears to be plunging towards the north, a hypothesis supported by the strong surface geochemistry trending towards the northwest. Everything we’ve seen so far suggests this zone is an Ironbark analogue, with the mafic host unit within ultramafic country rock and the same geochemistry and alteration.
“In addition to those results, our first-pass aircore drilling on broad surface anomalism north of Ironbark has intersected gold grades up to 0.55 g/t gold, with anomalous gold results in multiple locations.
“Remember, this is aircore drilling within the weathered profile so we’re not expecting ore grades in the first program. We are now planning follow-up drilling into all these targets.”
Extended mineralisation trend
Further exploratory work has identified gold mineralisation that appears to plunge towards the northwest, suggesting an extended mineralisation trend along the Ironbark Corridor.
In addition to the high-grade intersections at Saltbush, preliminary aircore drilling 2 to 4 kilometres north of Ironbark has intersected gold grades up to 0.55 g/t gold in multiple locations, indicating widespread mineral potential.
The company has planned a comprehensive follow-up drilling program, set to commence in early May, aimed at testing these and other targets along the more than 14-kilometre-long Ironbark corridor.
