The MGP plant comprises the key grinding and gravity recovery infrastructure required to underpin a proposed 120,000tpa gold processing facility and complete the front-end gold recovery circuit at Radio. 1 ASX:WIN “WIN Completes Acquisition of Radio Gold Mine” released 24 September 2025 WIN SECURES KEY PROCESSING INFRASTRUCTURE FOR RADIO GOLD PROJECT 18 June 2026 2 ABN 77 648 687 094 Level 4, 220 St Georges Tce Perth, WA 6000 PO BOX 7713 Cloisters Square WA 6850 T: +61 8 6381 7250 F: +61 8 6381 7299 info@winmetals.com.au www.winmetals.com.au ASX:WIN Figure 1: Ball Mill and associated plant The MGP plant was initially constructed in 2014 as a plant configured to liberate a tantalite concentrate from pegmatite ore. The plant ran for approximately 1 month prior to being decommissioned thereafter sitting idle until acquisition by Tungsten Mining in 2017. As can be viewed below (Figures 6-17) the plant presents in excellent condition. The attraction for WIN is the ball mill size and plant design capacity is an ideal fit for our intended production rate of 120,000tpa or 15tph at the grind size indicated for maximum gold recovery. With an option secured over this critical piece of infrastructure, detailed costing and design integration can now be advanced. Managing Director and CEO, Mr Steve Norregaard commented: "Securing this option is another practical step towards bringing Radio into production. The plant is well matched to the scale of the project and provides a fit-for-purpose processing solution that can be integrated with the existing infrastructure already in place at site. Our focus has always been on identifying the right development pathway for Radio while maintaining capital discipline. The opportunity to acquire a near-new grinding and gravity circuit at a fraction of replacement cost aligns strongly with that objective and has the potential to materially reduce development capital requirements." The Company has been evaluating processing options for its Radio Gold Project comparing the relative merits of ore tolling and ore purchase agreements from a cost perspective compared with options to build a fit for purpose gravity or gravity plus leach process plant onsite at the Radio Gold Mine. Ore tolling and ore purchase arrangements have been assessed by the Company and based on current market conditions and available discussions, are considered less attractive than onsite processing alternatives.

The site is accessed via the Mt Jackson Road, providing direct entry to the Project area. Figure 15: Location of Radio Gold Project Gold mining at the Radio Gold Project commenced in 1918, with approximately 71,000 ounces produced at an average head grade of 38 g/t Au between 1918 and 1974. Underground operations were re‑established in 2018 using the existing shaft, followed by development of a new surface portal and ~330 metres of decline to the historic second level. A shallow open pit to ~25 metres depth was also completed however, most near surface mineralisation remains unmined, providing potential for exploitation. Historic production records for Repeater, Radio South and Green Harp are limited. Mining at Repeater has been confined to a very shallow open pit (<5 m) and minor underground development, while Radio South and Green Harp have been exploited via underground workings. Recent drilling at Radio South has defined theextent of historical stoping,and historicmineplans for Green Harp have been sourced to support ongoing geological and mining studies. The Radio mine site remains intact and dewatered, with all necessary underground infrastructure in place, ideally positioning the Project for rapid restart.
