Great Boulder Resources (ASX:GBR) has found “thick” high-grade gold reaching up to 20 grams per tonne through its reverse circulation drilling program at its Eaglehawk prospect in Western Australia.

The drilling work revealed intercepts which were defined by high grade but also thick, with the standout being 29 metres at 4.79g/t of gold from 76m, including four metres at 20.50g/t Au from 92 metres in hole 25MBRC002.

This is the highest-grade intercept ever found at the Eaglehawk prospect.

Great Boulder has also been progressing aircore drilling at Side Well South, picking up intercepts such as two metres at 1.66g/t Au from 57m in 25SWAC047, and two metres at 1.30g/t Au from 52m in 25SWAC034.

Managing director Andrew Paterson said the discovery at the Side Well Gold project was a strong indication of Eaglehawk’s potential. “We are very excited to have intersected a thick zone of high-grade, vein-hosted gold on the target dacite contact in our second hole for the year at Eaglehawk,” he said.

“This result validates our strategy of targeting high-grade contact-related veins along the dacite unit. If we see continued success with this strategy, it has the potential to have a meaningful impact on our resource growth ambitions.

“We thought it appropriate to rename Mulga Bill North to Eaglehawk to distinguish it as a large high-grade target in its own right. Drilling has defined gold mineralisation over more than 900m of strike, and it remains open to the north where there is little or no drilling over a strike length of approximately 4km.”

He added the target represented a notable area of highly prospective geology which has been untested up to now.

GBR has been trading at 7cps through Wednesday morning.
