WIN Metals has boosted its Radio Gold Project resource by 21% to 49,600 ounces at 4.2 g/t, underpinning plans for a near-term development decision backed by increased resource confidence and ongoing mining studies.
- Radio Gold resource grows 21% to 49,600 ounces
- Indicated resource rises 21% to 25,500 ounces
- 4,200 metres drilling enhances confidence in key mining zones
- Mining studies and permitting advancing toward development
- Metallurgical tests confirm conventional processing amenability
Resource Expansion Signals Project Momentum
WIN Metals Ltd (ASX:WIN) has reported a 21% increase in its Mineral Resource Estimate (MRE) for the Radio Gold Project in Western Australia, now totalling 49,600 ounces of gold at 4.2 grams per tonne (g/t) from 366,000 tonnes. This update reflects a 73% growth in the overall resource since WIN acquired the project in August 2025, with the indicated category rising 21% to 25,500 ounces, enhancing confidence in the near-term mining areas.
The company’s 2026 drill program, comprising 4,200 metres of reverse circulation (RC) drilling and underground face sampling, has been pivotal in derisking the front end of the mine plan, particularly at the Radio Main and Repeater deposits. Notable high-grade intercepts include 3 metres at 19.5 g/t gold at Repeater and face samples exceeding 300 g/t at Radio, underscoring the quality of the mineralisation.
Advancing Mining Studies and Development Planning
With half the resource now classified as Indicated, WIN is progressing detailed mine design, scheduling, and permitting activities. The updated MRE applies a 0.5 g/t cut-off to material within 50 metres of surface for open pit scenarios and a 1.0 g/t cut-off for potential underground mining below this depth, reflecting realistic extraction parameters for narrow vein gold deposits.
Metallurgical testwork confirms the ore’s amenability to conventional gravity and cyanide leach processing, with historical and recent tests reporting gold recoveries consistent with industry standards and high gravity recoveries of 85.9%. These results support the feasibility of established processing routes, reducing technical risk ahead of a potential development decision.
Geological Context and Resource Classification
The Radio Gold Project lies within the Archean Southern Cross Greenstone Belt, a well-known gold province characterised by structurally controlled, high-grade quartz vein mineralisation. The updated resource model incorporates nine mineralised domains, with grade estimation using an inverse distance weighted cubed (IDW³) algorithm and a revised high-grade top-cut increased from 30 g/t to 100 g/t to better reflect the nuggety nature of the deposit.
Resource classification reflects drill density, proximity to underground development, and geological continuity. Indicated resources are defined where drill spacing is approximately 20 metres and supported by underground face sampling, while inferred resources cover areas with wider drill spacing and moderate confidence. No material is classified as Measured.
Next Steps Toward Production
WIN Metals plans to finalise the mining schedule incorporating the updated MRE, advance permitting for underground and open pit mining, and complete financial modelling aligned with preferred processing options. The company aims to reach a final investment decision to commence operations shortly, positioning Radio as a key near-term production asset.
Alongside Radio, WIN maintains a diversified portfolio including the Mt Edwards Nickel Project, Faraday-Trainline Lithium Project, and Butchers Creek Gold Project, reinforcing its footprint across critical and precious metals in Western Australia.
Bottom Line?
WIN Metals’ substantial resource upgrade at Radio Gold Project sets the stage for a development decision, but execution risks remain as permitting and processing evaluations continue.
Questions in the middle?
- How will ongoing permitting and approvals influence the timing of Radio’s development decision?
- What processing option will WIN Metals select based on confirmatory metallurgical testwork?
- Can further drilling convert more inferred ounces to indicated and improve mine plan confidence?
