WIN Metals has confirmed that ore from the Radio Gold Project is free-milling and amenable to conventional processing, with metallurgical testwork returning combined gravity and leach extractions of between 98.6% and 99.0% over 24 hours at a P80 grind size of 75 μm.

The testwork program, conducted by Fremantle Metallurgy on reverse circulation drill samples, demonstrated bulk gravity gold recovery components ranging from 63% to 76%. Whole-ore cyanidation tests at the same 75 μm grind size yielded 24-hour gold extractions of 90.1% to 94.7% for sample head grades between 5.7 and 6.4 g/t Au. Historical 2018 testwork also achieved approximately 99% total gold extraction, supporting the strong metallurgical response.

To support the proposed 120,000 tpa Radio Gold operation, WIN Metals secured a six-month option in June 2026 to acquire a modular gravity processing plant from Tungsten Mining NL. The option, which expires around December 2026, requires a final cash payment of $250,000 and $250,000 in shares.

“This last bit of confirmatory news concludes the relevant technical evaluation of the project and what good news it is with very high gravity gold recoveries achieved and excellent leach recoveries on gravity tails material indicating potential overall recoveries in excess of 95% in a plant operating scenario as being readily achievable.”

WIN Metals expects to announce re-start study outcomes for the Radio Gold Project shortly, following confirmation of the >95% combined recoveries.
