Gorilla Gold Hits 97.5% Gold Recovery, Ramps Up to 5 Rigs for Q4 Resource Update

Exceptional Metallurgical Results Signal Strong Project Economics

Gorilla Gold Mines Ltd (ASX, GG8) has delivered a promising update from its Comet Vale Gold Project in Western Australia, revealing exceptional initial metallurgical test results from the Lakeview Prospect. The company reported a total gold recovery rate of 97.5% from a representative sample, combining gravity extraction and cyanide leach methods. This level of recovery is notable for its potential to underpin efficient and cost-effective processing using conventional milling techniques prevalent in the region.

The standout figure includes a 55% recovery through gravity extraction alone, complemented by a rapid 94.5% recovery after just two hours of cyanide leaching. These results suggest that the gold mineralisation at Lakeview is amenable to standard processing routes, a critical factor in assessing the project's economic viability ahead of the maiden Mineral Resource Estimate (MRE) expected in the fourth quarter of 2025.

Intensified Drilling Campaign to Expand Resource Base

Supporting the metallurgical success, Gorilla Gold has ramped up its exploration efforts with 4-5 rigs currently active across the Comet Vale tenements. Three diamond rigs focus on extending the high-grade King Kong Lode at Lakeview down-dip, while two reverse circulation rigs explore the Silverback trend, including Cheer and Happy Jack prospects. This aggressive drilling program aims to delineate the full extent of mineralisation and feed into an updated resource model later this year.

The Comet Vale Project itself boasts a rich history, having produced over 200,000 ounces of gold at an impressive average grade of 20 grams per tonne. Its location within granted mining leases and proximity to multiple operational mills within 100 kilometers further enhances its strategic appeal. Gorilla Gold’s exploration strategy targets high-grade zones within brownfields settings, leveraging existing infrastructure to accelerate development timelines.

Broader Metallurgical Testing and Project Development Plans

Building on the initial Lakeview results, Gorilla Gold plans a comprehensive metallurgical testwork program encompassing other key prospects such as Cheer and Sovereign North. These studies will inform broader mining studies and feasibility assessments, crucial steps toward advancing the project toward production.

CEO Charles Hughes highlighted the significance of these findings, noting that the positive metallurgical response addresses a critical question regarding the project’s economics. He emphasized that the upcoming maiden resource and ongoing drilling will provide a clearer picture of the project's scale and potential.

Meanwhile, Gorilla Gold is also advancing its Mulwarrie Project, with plans to grow its resource base and initiate mining studies, reflecting a dual-track approach to growth within its portfolio.

Outlook and Market Implications

With drilling intensifying and metallurgical programs expanding, Gorilla Gold is positioning itself for a pivotal phase of development at Comet Vale. The combination of high-grade mineralisation, excellent gold recoveries, and proximity to infrastructure bodes well for the project's future economics. Investors and analysts will be watching closely for forthcoming assay results and the maiden resource estimate, which will be key milestones in validating the project's value proposition.
