Breaker Resources (ASX: BRB) has unearthed underground potential at its Lake Roe project after drilling intersected up to 30.85 grams per tonne gold at the Bombora discovery.
The latest results from the step out drilling campaign will be included in the maiden JORC resource due next month.
Gold mineralisation was stuck in numerous intersections with better underground intervals including 9m grading 25.55g/t, 5.36m grading 30.85g/t, 15m grading 3.37g/t gold and 2.3m grading 25.46g/t gold.
Additionally, drilling within the Tura and Mindil lodes revealed visible gold with assay results pending.
“We are starting to see several new high-grade reconnaissance gold intersections 150-300m vertically below surface which display excellent indicative continuity,” Breaker executive chairman Tom Sander noted.
“This materially upgrades the underground mining potential at Bombora, which is noteworthy because it has potential to add multiples to any shallow gold resource constrained by the economic limits of open pit mining,” Mr Sander said.
Gold at Bombora has been identified across a strike of 2.2km with mineralisation remaining open at depth and to the east.
Mr Sander said this increased the potential for a larger resource and the ongoing gold hits after 12 months of drilling “de-risked” the project’s future.
Although the maiden JORC resource is due mid-April, Breaker stated it will continue with its resource drilling campaign “well after” the resource has been released.
Results will be incorporated into resource upgrades and pre-development studies, which Mr Sanders said will be ramped up to evaluate the range and scope of potential development scenarios.
Breaker will also evaluate the 500 square kilometre project’s potential outside of the Bombora discovery.
Today’s news follows the company’s bonanza intersection at Bombora that was reported in January which returned 9m grading 35.88g/t gold from 131m below surface. A wider lower-grade near surface intersection of 36m grading 2.78g/t gold was also identified.
Bombora is part of an 8km greenfields gold system at Lake Roe which is about 100km east of Kalgoorlie in WA.
The project comprises six granted exploration licences, with mineralisation found at near-surface and at depth.
