The 46% increase in the Mineral Resource to 41,000 ounces has delivered the scale and confidence needed to advance detailed mine design, scheduling and development studies, with a significantly improved resource quality profile and approximately half of the updated resource now classified as Indicated. Importantly, the work completed during the period positions the Company to assess a development decision in Q2 2026, as we further evaluate both open pit and underground mining scenarios across the broader Radio portfolio. The acquisition of Princess Royal and the option over Stumpy Doodle further underpin this strategy, adding additional high-grade satellite opportunities that have the potential to complement and enhance future development outcomes. Together with strong exploration results that support the upgraded resource, WIN is now well placed to advance a scalable, high-grade gold project in the Southern Cross Goldfields.” Key activities and outcomes by project are summarised below. RADIO GOLD PROJECT (100% WIN) Southern Cross Region, Western Australia MINERAL RESOURCE UPDATE1 The March Quarter was highlighted by a substantial upgrade to the Mineral Resource Estimate at the Radio Gold Project in WA, where contained gold increased by 46% to 41,000 ounces at 3.70 g/t Au, supported by approximately 9,000 m of drilling completed in 2025. Approximately 21,000 ounces or 50% of the updated resource is now classified as Indicated, materially improving geological confidence and providing a stronger platform for mine design and early-stage economic assessment. The program also delivered maiden Mineral Resource Estimates for the Repeater, Radio South and Green Harp domains, adding approximately 12,900 ounces and demonstrating the broader scale potential of the Radio mineralised system. Detailed mine planning, scheduling and development studies have commenced, leveraging existing underground infrastructure and largely unmined near-surface mineralisation, with further drilling and approvals work aimed at supporting a potential development decision by end of Q2 2026 (noting that no Ore Reserves, production targets or forecast financial information are being reported at this stage).

Figure 1: Radio Gold Project prospect location and drill traces (Surface mineralisation refers to the Mill domain) EXPLORATION RESULTS2 During the Quarter, WIN reported the remaining assay results from its highly successful maiden 2025 drilling program at the Radio Gold Project, confirming shallow gold mineralisation at the historic Radio South and Green Harp mines and identifying multiple near-surface ore-grade intercepts around the Radio Mill area. Drilling at Radio South and Green Harp returned several high-grade intercepts, including 3 m at 4.36 g/t Au from 15 m and 1 m at 8.03 g/t Au from 57 m, with mineralisation remaining open down-dip and along strike. Around the Radio Mill, shallow holes intersected gold from surface, highlighting a thin, flat-lying veneer of gold-bearing material interpreted to be related to historical processing activities and representing a potential low-cost source of near-surface feed. Surface sampling at Repeater confirmed that the main lode projects to surface, with pit-floor sampling returning up to 29.6 g/t Au, providing important geological control where drilling is constrained by the existing open pit. Collectively, these results further support Radio’s potential as a near-term production opportunity, with work now focused on defining additional Mineral Resources, advancing mine design studies, scheduling and costing and evaluation of processing options targeted for implementation in 2026. 2 ASX:WIN “Radio Gold Project Exploration Results” Released 21 January 2026 4 March 2026 Quarterly Report 30 April 2026 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 2: Radio South and Green Harp long section looking north west.

The drilling, together with ongoing underground sampling, is designed to support detailed mine planning at the Radio and Repeater deposits. PRINCESS ROYAL AND STUMPY DOODLE ACQUISITION3 During the Quarter, WIN Metals executed two value-accretive gold transactions that materially enhanced the scale and optionality of the broader Radio Gold Project. The Company has agreed to acquire the fully permitted Princess Royal Gold Mine, located approximately 80 km from Radio and 5 km from the Edna May processing hub, and secured an exclusive 12‑month option over the high-grade Stumpy Doodle Gold Mine, situated 10 km north of Radio, with both assets positioned on granted Mining Leases to support a streamlined development pathway. Princess Royal brings an Exploration Target of 26,000–40,000 tonnes at 8.0–12.0 g/t Au for 7,000–15,000 ounces and is supported by exceptional historicgrades, including diamond intercepts such as 2 m at 31.47 g/t Au and 2 m at 30.47 g/t Au, while Stumpy Doodle adds a highly prospective satellite position with historical production of ~2,300 tonnes at 11 g/t Au for ~830 ounces. Immediate work programs are being advanced, with drill planning underway at Princess Royal and exploration scheduled to commence at Stumpy Doodle during the option period, collectively increasing the Project’s potential high-margin ore sources and strengthening development flexibility for future processing and production scenarios. Cautionary Statement – Princess Royal Exploration Target An Exploration Target is a statement or estimate of the exploration potential of a mineral deposit in a defined geological setting where the statement or estimate, quoted as a range of tonnes and a range of grade or quality. The potential quantity and grade of the Princess Royal Exploration Target is conceptual in nature and, as such, there has been insufficient exploration drilling conducted to estimate a Mineral Resource. At this stage it is uncertain if further exploration drilling will result in the estimation of a Mineral Resource. The Exploration Target has been prepared in accordance with the JORC Code 2012. 3 ASX:WIN “WIN Builds Scale at Radio Gold with High Grade Acquisitions” Released 31 March 2026 6 March 2026 Quarterly Report 30 April 2026 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 4: Location of Radio, Princess Royal and Stumpy Doodle Projects BUTCHERS CREEK GOLD PROJECT (100% WIN) Kimberley Region, Western Australia No field activities were undertaken during the Quarter, with efforts focused on ongoing stakeholder negotiations. Key tenement applications at Butchers Creek and Golden Crown progressed, targeting the conversion of existing exploration licences to mining leases to facilitate potential future mining activities at the Project. Drilling is planned during the 2026 field season at Golden Crown to improve resource confidence so that the deposit can be assessed for future mining studies at the Project. MT EDWARDS NICKEL PROJECT (100% WIN) Southern Goldfields, Western Australia Exploration for groundwater was completed during January over the Mt Morgans aquifer, with aircore drilling successfully intersecting thick water bearing sand units considered prospective for production bores to support future processing requirements at Mt Edwards. Securing a reliable, high-quality water supply is a key enabling milestone for any potential development and processing operation at the Project. Production bore drilling is now planned for completion within the next 6 months. The Company has carried out modelling to consider the merits of downstream processing of nickel concentrates from Mt Edwards to produce nickel sulphate/pCAM as an alternative to simply selling a low value concentrate into world markets incurring significant transport costs, penalties for deleterious elements and low payabilities. This study work remains ongoing as at the end of the Quarter. 7 March 2026 Quarterly Report 30 April 2026 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 FARADAY-TRAINLINE LITHIUM PROJECT (100% WIN) Southern Goldfields, Western Australia Metallurgical test work focused on critical mineral liberation via flotation commenced during the Quarter, targeting rubidium deportment within the lithium-bearing pegmatites.
