- Great Boulder extends gold mineralisation at Side Well South
- Discovery at Golden Bracelet hints at new lode potential
- Northern Central Corridor drilling to expand resource footprint
Great Boulder Resources (ASX:GBR) continues to advance its exploration success at the Side Well South Project in Western Australia, revealing promising drill results that expand the mineralisation footprint of the historic Golden Bracelet mine.
The company recently reported the final 16 drillholes from a 23-hole reverse circulation (RC) campaign, spanning 3,100 metres. Noteworthy results include an intersection of 9 metres at 2.28 grams per tonne (g/t) gold from 35 metres depth, with a high-grade 1 metre section at 9.18g/t gold from 36 metres. Additionally, a significant hit of 4 metres at 11.70g/t gold from 116 metres was recorded in drillhole 25SWRC008. This interval, currently based on composite sampling, will be reassayed at 1-metre intervals to refine accuracy.
This drillhole is considered by Great Boulder to signal the presence of a new lode of mineralisation. Plans are underway to further test this zone in upcoming drilling efforts. The company's broader strategy includes assessing both near-surface and deeper potential, especially given the proximity to existing deposits like Ironbark and Mulga Bill.
At the Golden Bracelet mine, recent findings suggest the mineralised strike extends beyond 200 metres and remains open to the north, south, and at depth. This reinforces the potential for Ironbark-style discoveries in the area, with near-surface gold offering flexibility in development planning and possible early-stage production scenarios.
Simultaneously, Great Boulder is conducting an aircore program near Mulga Bill and preparing to commence wide-spaced drilling to the north of Eaglehawk. These drill fences aim to define the northern limits of the Central Corridor, a highly prospective gold zone with a strike length of over 6 kilometres. The full extent of this intrusive-related gold system remains undetermined.
Earlier, seven drillholes had already delivered encouraging results, such as 14 metres at 1.64g/t gold from 83 metres, including 4 metres at 3.59g/t gold. In parallel, shallow aircore drilling at Saltbush and extensive RC drilling at Side Well South are progressing, with results pending. A recently completed RC program at the southern end of Ironbark is also awaiting results to determine if mineralisation extends further south.
Great Boulder Resources (GBR) will share more insights during its participation at the Noosa Mining Investor Conference scheduled for 23–25 July 2025. The company remains focused on unlocking the full potential of its assets as global gold production trends remain stable amid strong market dynamics.
