The Mine Development and Closure Plan (MDCP) was lodged with the Department of Mines,Petroleum and Exploration (DMPE) on 11 September 2026 and the Works Approval application was submitted to the Department of Water and Environmental Regulation (DWER) on 18 September 2026. Managing Director and CEO, Mr Steve Norregaard commented: “The lodgement of these key permit applications represents another solid step forward in our restart schedule for Radio. Now with a clear roadmap to redevelopment mapped out we can turn our minds to funding requirements leading to an FID decision and building the project bona fides through mine life extensions and addition of other resources in the region.” KEY RESTART PERMITS LODGED FOR RADIO GOLD PROJECT 25 September 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 TheMine Developmentand Closure Plan (MDCP),lodged on 11 September 2026,provides a detailed description of the Project, its environmental setting, potential impacts and proposed management measures. The MDCP incorporates the relevant background studies and demonstrates that the Company has undertaken appropriate design, risk assessment and environmental management planning to support development of the Project. The MDCP also addresses post-mining land management and proposed mine closure obligations, including the measures required to manage rehabilitation and closure outcomes. Works Approval documentation includes the quantification and assessment of a projects planned emissions and discharges to the environment and the mechanisms proposed to manage these emissions through appropriate design features or management. This Works Approval application was submitted on the 18 September 2026 to support construction of key components of the Radio Gold Project and allow for the mining and physical processing of gold ore. Yilgarn Precious Metals Pty Ltd (YPM), a wholly owned subsidiary of WIN Metals, currently holds an Environmental Licence for Category 6 (Mine Dewatering) and Category 64 (Class II Putrescible Landfill Site) activities. This application, specifically seeks approval for construction of the processing plant and an embankment raise of the existing TSF2 under Category 5 – Beneficiation of Metallic or Non-metallic Ore. Location and Project History The Radio Gold Project is situated within the Shire of Yilgarn in Western Australia, approximately 8 km north of Bullfinch and 38 km north-west of Southern Cross in Western Australia’s Eastern Goldfields. The site is accessed via the Mt Jackson Road, providing direct entry to the Project area.

Underground operation was re‑established in 2018 using the existing shaft, followed by development of a newsurface portal and 330metres of decline to the historicsecond level to enable mechanised mining. A shallow open pit to 25 metres depth was also completed however,most near surface mineralisation remains unmined,providing potential for future low-cost open pit production alongside underground targets. Figure 2: Radio boxcut and portal overlooking the proposed ROM and processing area 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 a potential rapid restart. WIN proposes to re commence mine production from both open pit and underground at Radio with processing onsite at a newly constructed 120,000tpa gravity and CIP circuit with tailings to be captured in an already existing tailings dam onsite, which will see an increase in capacity to accommodate 450,000t of new tails.

The Radio Gold Project, located 8 km north of Bullfinch and approximately 38 km northwest of Southern Cross, is another cornerstone asset within WIN’s portfolio. Over its mine life, Radio produced roughly 71,000 ounces of gold at an average grade of 38 g/t Au. WIN’s 2026 Mineral Resource Estimate for the Project totals 366,000 t @ 4.20 g/t Au for 49,600 ounces of contained gold1 . The Mt Edwards Nickel and Faraday–Trainline Lithium Projects are located near Widgiemooltha, approximately 80 km south of Kalgoorlie-Boulder and 30km south of Kambalda. • The Mt Edwards Nickel Project is a collection of eleven (11) nickel deposits with a combined mineral resource of 12.7 Mt @ 1.43% Ni for 180,900 t of contained nickel2 . • The Faraday-Trainline Lithium Project hosts a reported mineral resource of 1.96 Mt at 0.69% Li2O3 . In the Kimberley region, the Butchers Creek Gold Project lies 30 km southeast of Halls Creek. The project is centred on a historic gold production area and hosts a global Mineral Resource of 5.6 Mt @ 1.98 g/t Au for 359,000 ounces of gold4 . Historical mining between 1995 and 1997 produced approximately 52,000 ounces.
