Great Boulder Resources has struck its highest-grade gold to date during drilling at the Eaglehawk prospect, part of the company’s flagship Side Well Gold Project near Meekatharra, WA.
“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,” managing director Andrew Paterson said.
“If we see continued success with this strategy, it has the potential to have a meaningful impact on our resource growth ambitions.”
Best gold to date
Reverse circulation (RC) drilling at Eaglehawk delivered an intersection of 29 metres at 4.79 g/t gold from 76 metres, including 4 metres at 20.50 g/t gold from 92 metres.
This is the highest-grade gold result from Eaglehawk to date, and has given GBR well-warranted confidence in its strategy of targeting contact-related high-grade gold veins.
Further aircore drilling at Side Well South also returned positive results, including:
- 2 metres at 1.66 g/t gold from 57 metres; and
- 2 metres at 1.30 g/t gold from 52 metres.
Recent results from RC drilling at Eaglehawk.
The RC drilling campaign at Eaglehawk consisted of 11 holes, targeting high-grade mineralisation along the dacite-andesite contact.
Hitting the target
Previous drilling in this area was positioned too far west, but the latest results have successfully identified wide, high-grade vein-hosted gold mineralisation.
Results are pending for the remaining nine RC holes.
At Side Well South, results from 62 aircore holes have defined multiple new gold intersections. One such hole returned 17 metres at 0.33 g/t gold from 93 metres to end-of-hole, pointing to the promise of further mineralisation within a felsic intrusive system.
RC drilling continues at Mulga Bill and Eaglehawk, with further exploration planned to define the northern extension of the contact-related dacite target.
The company has also completed a heritage survey to facilitate additional drilling across key targets, including areas north of Eaglehawk and priority zones at Tal Val.
Follow-up drilling at Side Well South is scheduled to start once heritage clearance is in. Meanwhile, assays are pending for 22 aircore holes drilled northwest of Saltbush and 16 RC holes from Eaglehawk and Mulga Bill.

Eaglehawk has landed
“We thought it appropriate to rename Mulga Bill North to Eaglehawk to distinguish it as a large high-grade target in its own right,” Paterson continued.
“Drilling has defined gold mineralisation over more than 900 metres of strike, and it remains open to the north where there is little or no drilling over a strike length of approximately 4 kilometres.
“This target represents a significant area of highly prospective geology that has never been effectively tested.
“Assays returned from recent aircore drilling at Side Well South have defined new gold intersections in several areas.
“A follow-up heritage survey over that area was completed last week and we expect to have follow-up drilling underway soon.”
