The Company’s Re-Start Study (Study), announced to the ASX on 24 August 20261 , outlined a low- capital pathway to gold production through an integrated open-pit and underground operation feeding a dedicated 120ktpa carbon-in-leach (CIL) processing plant. The Project is located approximately 8km north-west of Bullfinch in Western Australia. Highlights and Project Progress • The approved MDCP covers development of a new open pit, recommencement of underground development and production, a lift on the existing tailings storage facility (TSF2), and operation of a processing plant and associated infrastructure • New Explosives Magazine Dangerous Goods license approved • Yilgarn Shire Development Approval for the Camp for up to 44 rooms behind the Tavern in Bullfinch received on 17 August 2026. Building Approval and Department of Water (DOW) approval for associated wastewater treatment plant remains pending. The existing Tavern is fully operational and currently accommodates up to 12 people • WIN submitted a Works Approval application on 18 September 20262 for the Processing Plant Construction and Tailings Dam Lift to the Department of Water and Environmental Regulation (DWER). The application remains under assessment • Equipment procurement and detailed implementation planning ongoing for final investment decision (FID) • Gravity Plant Acquisition and Relocation to commence Monday the 16 of November. (ASX announcement dated 18 June 20263 ) • 3,500m RC Drilling Program at Radio, Princess Royal and Stumpy is scheduled to commence 20 November 2026 1 ASX: WIN “Radio Gold Project Re-Start Study” Released 24 August 2026 2 ASX: WIN “Key Restart Permits Lodged for Radio Gold Project” Released 25 September 2026 3 ASX: WIN “WIN Secures Key Processing Infrastructure for Radio Gold” Released 18 June 2026 RADIO GOLD PROJECT - MINE DEVELOPMENT AND CLOSURE PLAN APPROVED 11 November 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: Radio boxcut and portal overlooking the proposed ROM and processing area Managing Direct and CEO, Mr Steve Norregaard commented: “Approval of the Mine Development and Closure Plan heralds an important step in derisking the restart strategy for the Project. With ongoing funding discussions, site prepatory works and detailed technical planning for execution on foot the company is well poised for a successful recommissioning in the New Year. Works approval now becomes the remaining regulatory hurdle prior to process plant and tailings dam construction activities commencing. I’d like to thank our various consultants who helped prepare the plan and supported us through this important body of work."

The Mt Edwards Nickel and Faraday Critical Minerals Projects are located near Widgiemooltha, approximately 80 km south of Kalgoorlie-Boulder and 30 km south of Kambalda. • The Mt Edwards Nickel Project is a collection of ten (10) nickel deposits with a combined mineral resource of 12.33 Mt @ 1.43% Ni for 174,540 t of contained nickel4 . • The Faraday Critical Minerals Project hosts a reported mineral resource of 5.8 Mt at 0.12% Rb2O & 0.3% Li2O for 6,950t Rb2O & 17,200t Li2O5 . 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 ounces6 of gold. Historical mining between 1995 and 1997 produced approximately 52,000 ounces. 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 global Mineral Resource Estimate for the Project totals 366,000t @ 4.22 g/t Au for 49,6007 ounces of contained gold. WIN Metals remains focused on advancing its diversified portfolio of critical and precious metal projects through targeted exploration and development activities aimed at building long-term shareholder value.
