Gorilla Gold has completed its maiden drilling at Mulwarrie and accelerated exploration at Comet Vale, aiming for significant resource upgrades in 2025. Recent drilling extends high-grade gold mineralisation, setting the stage for expanded Mineral Resource Estimates later this year.
- Maiden Mulwarrie drilling program completed; rigs moved to Comet Vale
- Q3 2025 target for significant Mulwarrie Mineral Resource Estimate upgrade
- Comet Vale drilling ongoing with multiple rigs; Q4 2025 MRE update planned
- Sovereign North mineralisation extended 100m along strike
- Projects located on granted mining leases near multiple operational mills
Mulwarrie Drilling Wraps Up, Comet Vale Accelerates
Gorilla Gold Mines Ltd (ASX – GG8) has announced the completion of its maiden drilling campaign at the Mulwarrie Project in Western Australia, marking a pivotal step in advancing its gold exploration portfolio. With drill rigs now demobilised from Mulwarrie and redeployed to the nearby Comet Vale Project, the company is intensifying its exploration efforts across both sites.
The Mulwarrie Project, situated on granted mining leases and strategically located near several operational mills including the Ora Banda facility just 10km away, is on track for a Mineral Resource Estimate (MRE) update in the third quarter of 2025. Based on drilling results released since February, Gorilla Gold is targeting a substantial increase in both contained gold ounces and grade, building on the existing inferred resource of approximately 78,700 ounces at 2.8 grams per tonne.
Comet Vale – Multiple Rigs and Expanding Mineralisation
At Comet Vale, the company has mobilised four to five drill rigs to advance growth and exploration drilling across key prospects including Sovereign, Sovereign North, Lakeview, and Cheer. The project boasts a historical production exceeding 200,000 ounces at grades above 20 grams per tonne, with a current resource estimate of nearly 96,000 ounces at 4.8 grams per tonne.
Recent drilling has extended high-grade mineralisation at the Sovereign North prospect by 100 metres along strike, highlighted by an intercept of 8 metres at 5.1 grams per tonne gold from 80 metres depth. This extension lies outside the current resource boundary, underscoring the potential for further resource growth. Exploration drilling has also commenced on the Silverback trend following receipt of Program of Work approvals, with a focus on delineating new mineralised zones.
Strategic Location and Forward Plans
Both Mulwarrie and Comet Vale projects benefit from granted mining leases and proximity to multiple operational mills within a 100-kilometre radius, enhancing their development potential. Gorilla Gold is concurrently advancing metallurgical testwork, hydrogeological studies, and permitting activities to support future mine planning.
Assay results from ongoing drilling campaigns are expected in the coming weeks, with the company working to increase laboratory capacity to expedite turnaround times. The upcoming MRE updates for Mulwarrie in Q3 and Comet Vale in Q4 2025 will be critical milestones, potentially reshaping the company’s resource base and growth trajectory.
CEO Charles Hughes praised the team’s execution and highlighted the strategic importance of these projects, noting the discovery of new parallel lodes and thick, high-grade intercepts that underpin the company’s confidence in delivering significant resource upgrades.
Bottom Line?
As assay results and resource updates approach, Gorilla Gold’s twin projects could redefine its growth outlook in the competitive WA gold sector.
Questions in the middle?
- Will the upcoming Mineral Resource Estimates confirm the anticipated grade and ounce increases at Mulwarrie and Comet Vale?
- How will the expanded mineralisation at Sovereign North influence the overall project economics and development timeline?
- What impact will accelerated assay turnaround and permitting progress have on Gorilla Gold’s near-term production plans?
