WIN Metals has announced a significant 46% increase in the Mineral Resource Estimate at its Radio Gold Project, now totalling 41,000 ounces of gold. This upgrade, supported by extensive drilling, sets the stage for imminent mine planning and a potential development decision by mid-2026.
- 46% increase in Radio Gold Project resource to 41,000 ounces
- Approximately 50% of resource now classified as Indicated
- Maiden resources declared for Repeater, Radio South, and Green Harp domains
- ~9,000 metres of drilling completed in 2025 underpinning resource growth
- Mine design and development studies underway targeting Q2 2026 decision
Resource Growth and Confidence
WIN Metals Ltd (ASX, WIN) has delivered a robust update to its Radio Gold Project in Western Australia, reporting a 46% increase in its Mineral Resource Estimate (MRE) to 41,000 ounces of contained gold at a grade of 3.70 grams per tonne. This substantial uplift follows the company's maiden drilling campaign since acquiring the project in August 2025, which included approximately 9,000 metres of reverse circulation drilling targeting extensions and satellite mineralisation.
Crucially, the updated resource now classifies around half of the contained ounces as Indicated, a category that reflects higher geological confidence and is essential for progressing towards mine planning and economic assessments. This improved classification provides WIN Metals with a stronger platform to advance the project towards development.
Expanding the Resource Footprint
The resource growth is not only quantitative but also geographic, with maiden Mineral Resource Estimates declared for the Repeater, Radio South, and Green Harp domains. These additions contribute nearly 13,000 ounces and highlight the broader scale potential of the Radio mineralised system beyond the historically mined Main and East lodes. The discovery of these new domains opens up strategic options for staged development, including potential high-margin starter pits.
WIN Metals has leveraged existing underground infrastructure and largely unmined near-surface mineralisation, positioning the project for a potentially rapid restart. Historical mining at Radio produced approximately 71,000 ounces at an impressive average grade of 38g/t, underscoring the project's quality and the opportunity for modern extraction techniques to unlock further value.
Technical Rigor and Future Steps
The company has undertaken comprehensive data validation and quality assurance, integrating historical datasets with recent drilling results into a consolidated geological model. Grade estimation employed advanced inverse distance weighting techniques, and metallurgical testwork confirms the ore's amenability to conventional gold processing methods, with high gravity recoveries supporting efficient extraction.
Looking ahead, WIN Metals is advancing detailed mine design, scheduling, and development studies, aiming to complete these by the end of Q1 2026. Additional drilling is planned to further expand and refine the resource base, while approvals and funding efforts are underway to support a potential development decision targeted for Q2 2026. The company remains cautious, noting that no Ore Reserves or production targets have yet been declared, and that development will depend on technical, economic, and regulatory outcomes.
Strategic Positioning within WIN Metals’ Portfolio
The Radio Gold Project forms a cornerstone of WIN Metals' diversified portfolio, which also includes nickel and lithium assets in Western Australia. The recent resource growth at Radio complements ongoing advances at other projects such as Butchers Creek and Mt Edwards, reflecting the company's broader ambition to transition into a cash-generating gold producer.
Managing Director Steve Norregaard emphasised the rapid progress since acquisition, highlighting the resource upgrade as a critical milestone that underpins the company's development ambitions. The combination of resource scale, improved confidence, and existing infrastructure positions WIN Metals well to capitalise on the Eastern Goldfields’ favourable mining environment.
Bottom Line?
With resource growth secured and mine planning underway, WIN Metals is poised for a pivotal development decision that could reshape its production profile.
Questions in the middle?
- What are the timelines and key milestones for securing regulatory approvals and funding?
- How will the maiden resources at Repeater, Radio South, and Green Harp influence the overall mine plan and economics?
- What are the potential challenges in converting the Indicated and Inferred resources into Ore Reserves?
