Flynn Gold Confirms 94% Gold Extraction at Golden Ridge Project

Robust Gold Recovery from Lower-Grade Samples

Flynn Gold Limited (ASX:FG1) has reported a 94% average gold extraction from 35 low to medium-grade samples taken from its Trafalgar Prospect within the Golden Ridge Project in northeast Tasmania. The metallurgical testing employed the LeachWELL™ cyanide leach method, confirming that even the lower-grade mineralisation outside previously modelled high-grade veins is amenable to efficient gold recovery.

This result aligns closely with earlier testwork at Trafalgar and nearby Grenadier Prospect, which achieved gold extractions of 94.5% and 94.9% respectively. The consistency across different grade ranges bolsters confidence in the potential for bulk mining approaches at Golden Ridge.

Implications for Processing and Development Pathways

The testwork focused on the cyanide leachability of lower-grade mineralisation to evaluate its suitability for conventional processing methods, such as those used at the nearby Henty Gold Mine operated by Kaiser Reef Limited. Flynn Gold has an executed non-binding Ore Purchase Agreement with Henty, which could provide a low-capital route to production by utilising existing processing infrastructure.

While the LeachWELL™ tests apply more intensive conditions than standard Carbon-in-Pulp or Carbon-in-Leach processes and used finely pulverised samples, they serve as a positive preliminary indicator. The company plans further metallurgical studies under conditions more representative of commercial operations, including investigations into beneficiation techniques to upgrade run-of-mine material into higher-grade concentrates.

Advancing Exploration at Brilliant Prospect

Complementing the metallurgical progress, a resource drilling campaign has commenced at the Brilliant Prospect, with approval for 21 drill holes totaling approximately 2,500 metres. This program aims to convert promising surface trench results, which revealed over 110 metres of continuous near-surface gold mineralisation, into a formal resource estimate. The drilling is part of a broader push to delineate the 3.5 to 5.4 million tonne exploration target across the Trafalgar, Brilliant, and Link Zone prospects.

These drilling efforts are critical to refining the geological model and underpinning future development decisions. The proximity of the Brilliant and Trafalgar prospects to infrastructure and the Henty processing plant enhances the project's strategic appeal.

Golden Ridge’s Strategic Position in Northeast Tasmania

Golden Ridge sits within a 9-kilometre intrusion-related gold system along the southern margin of the Golden Ridge Granodiorite. The region’s geology shares significant similarities with Victoria’s prolific goldfields, yet northeast Tasmania has historically seen less exploration investment. Flynn Gold’s focused tenure and exploration program aim to unlock this underexplored province’s potential.

The company’s portfolio also includes other Tasmanian projects with polymetallic potential, such as the Henty silver-lead-zinc and Firetower tungsten-gold projects, positioning Flynn Gold as a diversified explorer in a mining-friendly jurisdiction with solid infrastructure and skilled workforce access.
