Gorilla Gold has reported a fresh set of high-grade intersections at Sovereign, including 9 metres at 7.9g/t gold, while drilling at Happy Jack confirmed a shallow lateritic zone above bedrock mineralisation. The results feed into planned 2026 resource updates across the company’s Western Australian projects, although true widths and economic significance remain unestablished.
- 9.0m at 7.9g/t gold at Sovereign
- 1.4m at 21.6g/t gold at Sovereign North
- Happy Jack lateritic gold intersected from surface
- Resource updates planned for Comet Vale, Mulwarrie and Vivien
- Further assays and follow-up drilling pending
Sovereign drilling delivers high-grade intersections
Gorilla Gold Mines Ltd (ASX:GG8) has added another batch of high-grade results to its North Kalgoorlie Hub, led by a 9.0-metre intersection grading 7.9g/t gold from 242.9 metres at the Sovereign deposit. The result came from diamond hole STEX178 and sits among several new hits along roughly 2 kilometres of strike.
At Sovereign North, STEX195 returned 1.4 metres at 21.6g/t gold from 39.2 metres, alongside a separate 0.3-metre interval grading 41.2g/t. STEX194 delivered 5.5 metres at 4.0g/t from 38.9 metres, while other notable results included 4.7 metres at 5.2g/t from 53.6 metres in STEX175 and 1.0 metre at 14.2g/t from 249.2 metres in STEX207.
The latest drilling covers the main lode, dark lode, shallow lode and footwall areas of Sovereign. It adds to the company’s Sovereign footwall discovery, which earlier drilling had traced beyond 1 kilometre of strike outside the existing 410,000-ounce, 4.2g/t resource. Gorilla has also said Sovereign is now permitted for underground activities, but the new intersections remain exploration results rather than an Ore Reserve or development decision.
Happy Jack confirms gold from surface
About 1 kilometre north of Sovereign, 17 reverse-circulation holes at Happy Jack have outlined a different style of mineralisation. Twelve holes intersected gold from surface, confirming a shallow lateritic zone above the bedrock lodes.
The near-surface results included 12 metres at 1.0g/t gold from surface in HJEX033, 12 metres at 0.9g/t in HJEX031 and 5 metres at 3.1g/t in HJEX023. Beneath that shallow zone, HJEX033 returned 2 metres at 11.0g/t from 93 metres, while HJEX011 produced 15 metres at 1.2g/t from 53 metres. The company said the lateritic zone could be relevant to future open-pit scenarios, but no mining study or production plan was disclosed.
Resource updates remain the next test
Gorilla’s North Kalgoorlie Hub currently carries 1.2 million ounces at 3.7g/t gold across Comet Vale and Mulwarrie, with Comet Vale accounting for a stated 0.86 million ounces at 3.7g/t. The company says substantial high-grade intersections from Comet Vale, Mulwarrie and Vivien sit outside their current resource estimates and are being prepared for updates in 2026. That process will determine how much of the drilling converts into defined mineral inventory, rather than merely adding an impressive list of intercepts.
Results from Lake View South and Cheer East were more modest and have been flagged for follow-up drilling, including 2 metres at 4.7g/t at Lake View South and 4 metres at 1.3g/t at Cheer East. Drilling continues across the North Kalgoorlie Hub and Vivien, with further assays pending; the company noted that laboratory turnaround times are currently slower than usual because of higher industry demand. The reported grades are down-hole widths, and Gorilla says true widths have not yet been determined.
Bottom Line?
The immediate catalyst is the planned 2026 resource work, which must show whether the high-grade intersections form continuous, mineable mineralisation rather than isolated drill results.
Questions in the middle?
- How much of the new Sovereign and Happy Jack mineralisation will be incorporated into the next resource estimates?
- Will follow-up drilling establish meaningful continuity and true widths at the shallow Sovereign North and Happy Jack zones?
- Can the pending assays and ongoing Vivien drilling maintain momentum while laboratory delays persist?
