Mulwarrie Drilling Yields 3.4m at 12.5g/t Au, Boosting Resource Prospects
Gorilla Gold has restarted drilling at its Mulwarrie and Comet Vale projects in Western Australia, reporting significant high-grade gold assay results that extend mineralisation beyond the current resource estimate. The company is advancing studies to push Mulwarrie towards development amid a strong gold price environment.
- High-grade gold assays extend Mulwarrie mineralisation beyond 350koz resource
- Two rigs active at Mulwarrie, three at Comet Vale for exploration and redevelopment
- Engineering and metallurgical studies underway to support Mulwarrie development
- Mulwarrie hosts multiple stacked lodes over 2.5km strike, open for expansion
- Gorilla targets significant resource upgrade and increased confidence categories in 2026
Drilling Resumes with Promising High-Grade Results
Gorilla Gold Mines Ltd has kicked off 2026 with a multi-rig drilling campaign at its key Western Australian gold projects, Mulwarrie and Comet Vale. Early assay results from Mulwarrie have delivered encouraging high-grade intercepts, including 3.4 metres at 12.5 grams per tonne gold and 6.2 metres at 2.2 grams per tonne, extending mineralisation beyond the current 350,000-ounce Mineral Resource Estimate (MRE).
These results, drilled approximately 50 metres down-dip from the August 2025 resource boundary, reinforce the continuity and scale of the Mulwarrie gold system. A shallower intercept of 3 metres at 4.2 grams per tonne in the northern part of the system further highlights the project's potential.
Strategic Growth and Development Focus
Mulwarrie hosts multiple stacked lodes spanning a 200-300 metre width and at least 2.5 kilometres strike, remaining open to the north and south. The project benefits from granted mining leases and proximity to existing gold processing infrastructure, including the Davyhurst Mill just 10 kilometres away.
Alongside ongoing drilling aimed at both infill and extensional targets, Gorilla has initiated geotechnical, engineering, and metallurgical studies to advance Mulwarrie towards development. This multi-disciplinary approach is designed to underpin a significant MRE upgrade and support future mining studies.
Comet Vale and Vivien Projects Also Advancing
At Comet Vale, three rigs are simultaneously conducting exploration drilling to grow the recent 860,000-ounce resource and support redevelopment activities. Meanwhile, the company is actively reassessing redevelopment opportunities at its Vivien Project, aiming to leverage its Goldfields portfolio amid a robust gold price environment.
CEO Charles Hughes expressed optimism about the year ahead, highlighting the strong start with high-grade results and the company’s aggressive drilling strategy to expand resources and advance development pathways.
Context and Outlook
Mulwarrie’s mineralisation is structurally controlled, associated with quartz veining and sulphide alteration within a greenstone belt known for significant gold endowment. The current drilling campaign is the first phase of a broader program targeting resource growth and upgrading confidence categories to support reserve definition.
With engineering and permitting work progressing in parallel, Gorilla Gold is positioning Mulwarrie for potential development decisions in the near term. The company’s integrated approach across its Western Australian assets aims to capitalise on favourable market conditions and deliver sustained growth.
Bottom Line?
Gorilla Gold’s strong start to 2026 at Mulwarrie sets the stage for a pivotal resource upgrade and development push.
Questions in the middle?
- How soon can investors expect an updated Mineral Resource Estimate reflecting these new drill results?
- What are the timelines and key milestones for advancing Mulwarrie towards production?
- How will the ongoing studies at Comet Vale and Vivien complement the company’s growth strategy?
