Gorilla Gold Comet Vale hits: inventory growth lens for mine planners
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Gorilla Gold has reported further high-grade intercepts at its Comet Vale project in Western Australia, including 9m at 7.9g/t gold from 242.9m at the Sovereign deposit plus additional shallower mineralisation. The company plans to roll these and earlier drilling results into updated mineral resource estimates later in 2026, targeting a larger gold inventory across the project. For mine planning and geotechnical teams, the mix of deep and shallow hits suggests potential for both underground extensions and near-surface stopes if continuity is confirmed.
Technical Brief
- Sovereign intercept commences at 242.9 m downhole, implying underground access rather than open pit.
- Reported 9 m interval at 7.9 g/t Au suggests potential for selective, narrow-vein stoping.
- Additional shallower intersections at Sovereign introduce potential for stacked lodes and multiple mining horizons.
- High-grade shoots at depth will drive need for detailed geotechnical domain modelling and stress assessments.
- Integration of new drilling into updated mineral resource estimates will refine stope shapes and dilution assumptions.
Our Take
The 9m at 7.9g/t gold intercept at the Sovereign deposit puts Gorilla Gold’s Comet Vale project into the same ‘high-grade’ narrative as Aureka’s Victorian assets in our database, which tend to attract interest from underground-focused mid-tiers rather than bulk-tonnage players.
Western Australia projects in our coverage with similar downhole intercept depths around 200–300m often transition quickly to underground scoping once resource updates land, suggesting Gorilla Gold may soon face decisions on decline access, ventilation, and water management rather than further shallow drilling.
