Gorilla Gold Mines Ltd (ASX:GG8) has released drilling results from its 100%-owned Comet Vale Gold Project in Western Australia, reporting high-grade intersections at the Sovereign Deposit and confirming near-surface lateritic gold mineralisation at Happy Jack, with mineral resource updates planned for Comet Vale, Mulwarrie and Vivien in 2026.

Key Points

  • Sovereign Deposit returned standout result of 9.0m @ 7.9g/t Au from 242.9m in STEX178, with Sovereign North returning 1.4m @ 21.6g/t Au from 39.2m in STEX195
  • Happy Jack confirmed near-surface lateritic gold, with 12 holes mineralised from surface, including 2.0m @ 11.0g/t Au from 93.0m in HJEX033
  • Results received for 27 holes at Sovereign, Sovereign North and the Sovereign footwall, covering approximately 2km of strike
  • Mineral resource updates planned for Comet Vale, Mulwarrie and Vivien in 2026, with drilling continuing across the North Kalgoorlie Hub and Vivien Project

Sovereign Deposit Drilling Results

Drilling at the Sovereign Deposit, which carries a resource of 410,000oz at 4.2g/t Au, returned results from 27 holes including diamond and RC pre-collars with diamond tails. The standout result was 9.0m @ 7.9g/t Au from 242.9m in STEX178. At Sovereign North, shallow diamond holes returned 1.4m @ 21.6g/t Au from 39.2m and 0.3m @ 41.2g/t Au from 40.8m in STEX195, and 5.5m @ 4.0g/t Au from 38.9m in STEX194. Further significant results included 1.0m @ 14.2g/t Au from 249.2m in STEX207, 2.0m @ 7.7g/t Au from 183.2m in STEX193, and 0.6m @ 17.2g/t Au from 310.4m in STEX233 at Sovereign South.

Near-Surface Lateritic Gold Confirmed at Happy Jack

At the Happy Jack target, 12 holes returned significant mineralisation from surface, confirming the presence of a near-surface lateritic gold zone. Key intersections included 5.0m @ 3.1g/t Au from surface in HJEX023, 12.0m @ 1.0g/t Au from surface in HJEX033, and 15.0m @ 1.2g/t Au from 53.0m in HJEX011. A high-grade intercept of 2.0m @ 11.0g/t Au from 93.0m was also recorded in HJEX033. The company disclosed that this lateritic gold zone sits over bedrock mineralisation at the Happy Jack area within the Comet Vale Project.

North Kalgoorlie Hub Resource Base and Planned Updates

The North Kalgoorlie Hub, which includes the Comet Vale and Mulwarrie Projects, hosts current mineral resources of 1.2Moz @ 3.7g/t Au and comprises more than 60km of high-priority drill targets. The Comet Vale Project holds a Mineral Resource Estimate of 0.86Moz @ 3.7g/t Au within granted Mining Leases adjacent to the Goldfields Highway. Mineral resource updates are planned for Comet Vale, Mulwarrie and Vivien in 2026. Drilling continues across the North Kalgoorlie Hub and Vivien Project, with further assays pending, according to the company's filing dated 9 November 2026.
