Gorilla Gold Mines Expands Sovereign Deposit with Multiple High-Grade Hits

High-Grade Gold Intercepts Extend Sovereign Deposit

Gorilla Gold Mines Ltd (ASX:GG8) has delivered another compelling batch of assay results from its flagship Sovereign Deposit at the Comet Vale Gold Project in Western Australia. The latest drilling campaign has returned multiple high-grade gold hits, including standout intercepts like 3.8 metres at 21.0 grams per tonne (g/t) Au from 374.3 metres and 2.1 metres at 24.8 g/t Au from 328.8 metres, reinforcing the deposit’s reputation as the highest-grade within the North Kalgoorlie Hub.

These results push the boundaries of the known mineralisation, with the current resource estimate at Sovereign standing at 410,000 ounces at 4.3 g/t Au over a 1.3-kilometre strike length. The company sees clear potential to extend this strike well beyond 2.5 kilometres, driven by multiple parallel lodes developing around a major lithological contact. The geometry of these lodes remains open, especially into the footwall, suggesting substantial upside still to be realised.

Aggressive Drilling Campaign Accelerates Resource Growth

In response to the encouraging assay results, Gorilla Gold has ramped up its drilling efforts, now operating five rigs across the North Kalgoorlie Hub. Four rigs are focused on Comet Vale, targeting both discovery and resource definition, while a fifth rig drills at the Vivien Project, which itself holds a 278,000-ounce resource at an average grade of 4.1 g/t Au.

Recent discoveries at Comet Vale, including the Diddy Kong, Donkey Kong, and Magilla prospects, have prompted follow-up drilling with two reverse circulation rigs, complementing diamond drilling targeting high-grade footwall lodes at Sovereign. This multi-rig approach underscores Gorilla Gold’s commitment to accelerating resource growth and testing greenfield targets within the hub’s 60-kilometre corridor of high-priority drill sites. The company’s track record is notable, having added 1.3 million ounces of new resources across its WA projects in 2025 alone.

Drilling assay turnaround times are currently slower than usual due to high industry demand, but the flow of results is expected to continue steadily, supporting ongoing resource updates. This drilling momentum builds on prior discoveries, including a significant new lode at Sovereign reported in early May 2026, which intersected 9.3 metres at 20.6 g/t Au in a previously untested footwall position, adding a new dimension to the project’s geological complexity and resource potential.

Comet Vale and Broader North Kalgoorlie Hub Strategy

The Comet Vale Project, hosting a Mineral Resource Estimate of 860,000 ounces at 3.7 g/t Au, has a rich history of high-grade production exceeding 200,000 ounces at over 20 g/t Au, with underground mining active as recently as 2020. The project is strategically positioned on granted mining leases adjacent to the Goldfields Highway, within reach of multiple operational gold mills.

The North Kalgoorlie Hub, comprising Comet Vale and the Mulwarrie Project, collectively holds a resource base of 1.2 million ounces at 3.7 g/t Au. The company’s exploration strategy is aggressive, aiming to discover, define, and develop new gold resources across this underexplored region. Recent step-out drilling at Mulwarrie has also shown promise, with high-grade gold intersections extending well beyond the existing 350,000-ounce resource, further expanding the company’s footprint in the area.

Ongoing Studies and Permitting Efforts

Alongside exploration, Gorilla Gold is advancing engineering, geotechnical, metallurgical, and hydrological studies to underpin future development. Project permitting activities are underway, critical for transitioning discoveries into production. The company continues to engage with Native Title groups, including Kakara Part A and Marlinyu Ghoorlie, reflecting its commitment to responsible development.

With multiple rigs turning and a pipeline of assay results forthcoming, the company is on track for further resource growth this year. The combination of high-grade intercepts, expanding mineralised zones, and an aggressive drilling program positions Gorilla Gold as a notable player in Western Australia’s gold exploration landscape.

These developments build on the company’s recent fourth shallow gold discovery and the new high-grade lode at Sovereign, highlighting a consistent pattern of exploration success. The ongoing drilling acceleration follows the company’s multiple high-grade intercepts reported earlier in the year, underscoring a clear trajectory of resource expansion within the North Kalgoorlie Hub.
