Great Boulder Resources (ASX:GBR) has announced plans for a follow-up drilling program at its Ironbark deposit in Western Australia, following encouraging results indicating the prospect remains open to the south. Recent reverse circulation drilling intersected shallow, high-grade gold mineralization 60 meters south of the existing resource. Drillhole 25IBRC004 yielded 8 meters at 9.07 grams per tonne gold from 113 meters, including a high-grade section of 5 meters at 13.84 g/t gold from 115 meters.
The company believes this indicates a potential plunge of the high-grade mineralization beneath the next line of aircore holes, located 170 meters further south. Managing Director Andrew Paterson stated that the results confirm the Ironbark deposit is open along strike and possesses the potential for resource expansion through additional drilling. The follow-up program will aim to assess the southern extension before updating the resource estimate. The scoping study for the Ironbark deposit remains on schedule for completion this quarter. Great Boulder’s Side Well Gold Project, which includes the Ironbark deposit, currently hosts a resource of 668,000 ounces at 2.8g/t gold. Concurrent reverse circulation drilling is underway at the Side Well South deposit to follow up on recent gold discoveries from earlier aircore drilling programs.
