The upgraded MRE provides us with the critical mass and confidence needed to move decisively towards development. The 46% uplift in contained ounces, underpinned by 50% of the 2026 MRE now sitting in the Indicated category, gives us a robust platform for mine design, scheduling and early-stage economic assessment aligned with WIN’s ambition to become a gold producer.” “The maiden resources at Repeater, Radio South and Green Harp have not only grown our inventory, they have opened up compelling options for high margin starter pits and staged development across Radio Gold Project Mineral Resource Update 29 January 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 the broader Radio camp. With this step change in the resource base, WIN will now sharpen its focus on mine planning and approvals work aimed squarely at positioning Radio for a development decision and transforming the Company into a cash generating gold producer.” WIN Metals Ltd (ASX: WIN) is pleased to report an updated Mineral Resource Estimate (MRE) for the Company’s 100% owned Radio Gold Project, located 38km north of Southern Cross in Western Australia. The updated January 2026 MRE now stands at 345,000 tonnes at 3.70g/t gold for 41,000 ounces, representing a 46% increase in contained ounces compared to the 2018 estimate1 (see Table 1 and Figure 1 below). The increase is driven by WIN’s successful drill program delivering maiden MRE for the Repeater and Radio South and Green Harp domains, which collectively contribute 114,000 tonnes at 3.50g/t gold for 12,800 ounces. Importantly, approximately half of the updated MRE, being 21,000 ounces are now classified as Indicated, reflecting improved confidence in geological continuity and data quality. Any potential near term development of the Radio Gold Project will remain subject to completion of further technical, economic and regulatory studies, receipt of all required approvals, and a positive production decision. No Ore Reserves have yet been estimated for the Radio Gold Project and no production target or forecast financial information is being reported in this announcement. Radio Gold Project – Mineral Resource Estimate Update: The Radio Gold Project is reported according to the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the ‘JORC Code’) 2012 edition. The 2026 MRE has been reported at a 0.5g/t Au cut-off above 50m from surface and 1g/t Au cut-off below 50m from surface totalling 345,000 tonnes at 3.70g/t Au for 41,000 ounces of contained gold. A significant increase to the total contained ounces at Radio Gold Project is attributed to the maiden resource estimates for the Repeater, Radio South and incremental ounces at Geen Harp and Mill domains outlined in Figure 1.

A total of 9,000m were drilled defining gold mineralisation at the Radio Main and East lodes whilst also targeting adjacent prospects of Repeater, Radio South, Green Harp and the historic Mill area for at surface gold bearing material illustrated below in Figure 3. Repeater, Radio South, Green Harp and the Mill domains are being reported for the first time in this 2026 MRE resulting in a significant increase to the total resource base. Figure 3: Radio Gold Project prospect location and drill traces (Surface mineralisation refers to the Mill domain) Location and Project History The Radio Gold Project is situated within the Shire of Yilgarn in Western Australia, approximately 8km north of Bullfinch and 38km north of Southern Cross in the Eastern Goldfields region of Western Australia. 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 new surface portal and ~330 metres of decline to the historic second 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. 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. Regional Geology Regional geology of the Radio Gold Project is defined by its position on the eastern margin of the Archean Southern Cross Greenstone Belt, within the central Yilgarn Craton of Western Australia. The Southern Cross Belt is an elongated, north-northwest trending sequence of predominantly mafic to ultramafic volcanic rocks, interlayered with banded iron formation (BIF) and minor sediments, intruded by voluminous granitoid domes such as the Ghooli Dome. The greenstone succession is highly deformed, manifesting major folding, faulting, and shearing, and is Radio Gold Project Mineral Resource Update 29 January 2026 6 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 metamorphosed primarily to amphibolite facies near the granite boundaries, with lower greenschist facies preserved in the belt core. The structural architecture of the region is dominated by major north to northwest trending axes and ovoid granitoid intrusions, resulting in complex dome-and-keel geometries. Gold mineralisation in the province is typically structurally controlled, associated with late stage transpressional shear zones and contacts between greenstones and granitoids. The Radio Gold Project lies at a key geological interface between sheared greenstones and the Ghooli granitoid, a setting recognised as highly prospective for high-grade, vein-hosted orogenic gold deposits. Local Geology The local geology of the Radio Gold Project is defined by its position along the eastern margin of the Archean Southern Cross Greenstone Belt, near the triple junction of three granite bodies. The immediate mine area comprises six steeply dipping, northwest-trending tectono-stratigraphic units. The northeastern part of the tenement is underlain by sub-cropping granite containing rafts of banded iron formation (BIF) and ultramafic–mafic schists. Adjacent to this granite is a 500–1,500m wide zone of strongly foliated amphibolite interlayered with BIF, ultramafic rocks and rare sediments. The Radio Gold Mine itself is developed within the Ghooli granite dome, with quartz lodes extending west from the main granite body. Granitic rocks at Radio display strong S2–S3 fabrics, indicative of syn to late-tectonic granite emplacement related to regional folding and faulting. The central part of the mine sequence is dominated by a 5km wide,northwest trending greenstone package of tholeiitic basalt and minor dolerite dykes, generally lacking pervasive foliation. BIFs within the greenstone sequence mark key stratigraphic horizons and are commonly associated with mafic and ultramafic schists in the southwest part of the project. Quartz lodes hosting gold mineralisation (Main and East lodes) exploit faulted granite contacts and adjacent amphibolite or sericite–kaolinite–chlorite–pyrite-altered granites. Mineralisation Interpretation Gold mineralisation at Radio is localised within two narrow high-grade quartz lodes, the Main (Footwall) Lode and the East (Hanging wall) Lode hosted by sheared granite along the greenstone belt margin. These subparallel lodes strike northeast and dip 30–60° east southeast, with continuity mapped for 130m underground and up to 700m at surface. The lodes comprise laminated to massive quartz veins within sericite altered granitic gneiss, typically 0.2–2m wide, with localised thickening in dilation zones. The vein system forms en-echelon arrays and stacked mineralised shoots (100–300m in length), commonly pitching obliquely to the main lode trend, reflecting a structurally complex, brittle–ductile shear system. Gold occurs predominantly as coarse, free gold, with accessory pyrite, galena and arsenopyrite, consistent with an orogenic quartz vein style. Three primary mineralised zones have been delineated at the Radio Gold Project: • Radio – The central and most developed zone of mineralisation comprising two closely spaced subparallelen-echelon lodes (Main and East lodes) positioned approximately 1 – 5m apart. These lodes represent the core of historical production and remain the principal focus for ongoing resource definition.

The lodes display a distinct structural orientation relative to the main Radio system, indicating a separate yet related deformation event controlling gold deposition. Figure 7: Section of Radio South lodes looking north east Historic Data Compilation Extensive validation and compilation work has been completed by WIN’s technical team, together with external consultant Amanda Prabhavalkar of Auram Resources, to verify and migrate historical datasets for the Radio Gold Project. This work has comprised: • Systematic validation of historical government datasets, assay files, drilling metadata and historical mine plans against available primary records. • Normalisation, consolidation and migration of multiple legacy databases into WIN’s corporate Datashed 5 cloud‑hosted geological data management system, ensuring consistent data structures and auditability. This comprehensive QA/QC and data migration program has materially increased WIN’s confidence in the integrity, completeness and suitability of the historical dataset for exploration and Mineral Resource evaluation purposes at the Radio Gold Project.

All 2025 drill holes were downhole surveyed using an Axis Mining Technology “Champ Gyro” north‑seeking gyroscopic tool at regular 15m or 30m intervals, depending on total hole length, and at end‑of‑hole depth. Drill hole collar coordinates were surveyed using a Trimble RTK‑DGPS, achieving an accuracy of approximately 0.02m horizontally and 0.1m vertically. Historic Historic RC drilling utilised face‑sampling bits to obtain 1m and composite intervals considered representative of the logged lithologies. Limited diamond drilling (DD) informing the 2026 MRE employed HQ and NQ core sizes, providing high‑quality samples suitable for detailed lithological and structural interpretation. All historic drill holes have been surveyed downhole using a combination of north‑seeking gyro and magneticsingle‑shot instruments. Historic collar coordinates were originally recorded in a local grid and subsequently converted to MGA94 Zone 50S for consistency with current regional datasets. Survey control for historical programs was established using a combination of differential GPS (DGPS) and total station methods, providing high‑accuracy collar positions. Verification and conversion of historical collar locations into the current coordinate framework has been completed, and the positional accuracy of earlier datasets is regarded as approximate but adequate for the purposes of current exploration, resource evaluation and reporting.

Each primary sample was split on‑rig using a rotary cone splitter to produce two equal sub‑samples in pre‑numbered calico bags, each weighing approximately 2–3.5kg. The residual reject material was temporarily stored in sample piles at the drill site. These collection methods were designed to ensure representative and consistent sampling. Primary RC samples were also split via the on‑rig cyclone splitter to produce representative sub‑samples of approximately 3–5kg. Most samples were dry, and any moist samples were processed using the same methodology.

A 200g pulp was retained for fire assay, and coarse rejects were archived. Sample sizes are considered appropriate for the style of mineralisation and expected grain size. Historic For RC and RAB drilling, primary samples were collected using off‑rig riffle splitters in historical programs and on‑rig cone splitters in more recent drilling, producing representative sub‑samples of approximately 3–5kg per interval. Samples were generally dry, and any wetter samples were treated using the same splitting methodology. Diamond drilling (DD) samples were obtained from half‑core, with nominal sample lengths typically ranging from 0.3m to 1.3m, selected on the basis of geological contacts and observed mineralisation. All samples were submitted to commercial laboratories for drying, crushing and pulverising prior to assay. Quality control procedures, including the routine insertion of blanks, field duplicates and certified reference materials, were variably applied in the more recent drilling programs to maximise sample representivity and monitor sample preparation performance. Overall, the sample sizes are considered appropriate for the style of mineralisation and expected grain size of the material sampled.

Samples were assayed by Bureau Veritas using a 40g fire assay with AAS finish, with a gold detection limit of 0.01ppm. As part of its standard laboratory protocols, Bureau Veritas also inserted its own standards, blanks and duplicates independent of the Company’s QAQC program. The combined QAQC datasets have been reviewed and are considered satisfactory, demonstrating acceptable accuracy and precision for the assay methods used. No umpire laboratory analyses have been undertaken at this stage. Bureau Veritas is NATA‑accredited to ISO/IEC 17025, providing additional confidence in the reliability of the analytical results. Historic Assaying for the Radio Gold Project has been undertaken by reputable, accredited commercial laboratories commonly used in the mining and exploration industry at the time of each program. Reverse circulation and diamond drill samples were analysed using industry‑standard methods, predominantly fire assay with AAS finish, aqua regia digestion with AAS or ICP‑based detection, and, in more recent programs, Photon Assay for gold. Historical reverse circulation (RC) and diamond drilling samples were assayed by laboratories including Analytical Services (WA) Pty Ltd, Yilgarn Assay Laboratory, ALS Perth, Genalysis Radio Gold Project Mineral Resource Update 29 January 2026 11 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 Laboratory Services and Ultratrace, using established gold assay methods such as 50g fire assay with AAS finish, aqua regia digestion with AAS or ICP‑MS finish, and, where appropriate, screen fire assay for coarse gold. The 2020 RC drilling program samples were analysed by ALS using Photon Assay, a rapid, non‑destructive, 500g analytical technique suitable for both coarse and fine gold, with performance considered comparable to conventional fire assay within acceptable precision limits. Historical QA/QC records for earlier drilling campaigns are incomplete or unavailable and have not been independently verified by the Competent Person. It is therefore uncertain whether routine insertion of certified reference materials, blanks and duplicates was consistently implemented in those programs. In contrast, recent drilling campaigns have applied systematic QA/QC procedures, including the insertion of standards, blanks and field duplicates, supplemented by internal laboratory QA/QC checks, which are considered appropriate for the style of mineralisation. No geophysical or handheld XRF data were used to support the publicly reported assay results. Estimation and Modelling Techniques Mineral resource modelling and grade estimation for the Radio Gold Project were completed using Micromine software. The interpretation defined nine mineralised domains to honour the spatial distribution of gold grades within the geometry of the identified quartz‑vein hosted lodes. Estimation domains were constructed by manually selecting intervals based on a combination of gold grade (nominally greater than 0.2g/t Au) and logged geology, with particular emphasis on quartz veining. Intervals containing quartz veining confirmed from chip tray photography were also included, even where gold grades fell below the nominal 0.2g/t Au threshold, to ensure geological continuity of the lodes. Gold grades were interpolated using an inverse distance weighted cubed (IDW³) algorithm, with gold (Au ppm) the only estimated variable. Sample data were composited to 1m downhole intervals prior to estimation. High‑grade capping thresholds were reviewed by domain and by sample type (drill samples versus face samples) using log‑probability plots, histograms and other statistical diagnostics. Top cuts of 30g/t Au were applied to the Main, East and Repeater lodes. Although statistical analysis indicated that a higher top cut could be justified for face samples alone, a conservative uniform 30g/t Au top cut was adopted across both face and drillhole datasets to prevent face samples from exerting an undue influence, given their shorter lengths and focus on visually mineralised zones. The block model used a parent cell size of 5m (E) by 10m (N) by 10m (Z), with sub‑blocking down to 0.3125m by 0.625m by 0.625m to accurately represent vein geometries and domain boundaries. Grades were estimated into the parent blocks, with the model rotated 60 degrees clockwise (azimuth N20o ) to align with the dominant strike of the mineralisation. Estimation domain codes were written to the block model so that, for each lode, only samples within the corresponding mineralised wireframe were used to estimate grades into that domain’s blocks. Anisotropic search ellipsoids were defined for each of the main lodes (Main, East, Repeater, Green Harp, Mill, Radio South and associated splays), with orientations set to reflect the interpreted dip, dip direction and plunge of mineralisation. Block grades were estimated using three successive search passes, with progressively expanding ellipsoid radii of approximately 45m (Major), 40m (Semi Major), 10m (Minor) for Pass 1. 60m (Major), 60m (Semi Major), 10m (Minor) for Pass 2. 120m (Major), 90m (Semi Major), 20m (Minor) for Pass 3. A sector‑based (octant) search was used to control sample distribution, with minimum and maximum sample and hole requirements adjusted Radio Gold Project Mineral Resource Update 29 January 2026 12 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 by pass, to balance data support and continuity. No discretisation points were applied within blocks (1x1x1). Model validation included comparison of composite and block model statistics at both global and domain scales, visual checks of grade distribution of the block model versus drillhole assays on sections and plans, and reconciliation of wireframe volumes against block model volumes. These checks confirmed that the block model estimates reasonably honour the informing data and appropriately reflect the interpreted geometry and grade tenor of the mineralised domains. Overall, the estimation outcomes are considered robust and suitable for reporting Mineral Resources at the Radio Gold Project. A bulk density of 2.62t/m³ was assigned in the block model to all fresh mineralised and waste blocks, based on water‑immersion measurements on drill core completed by ALS in April 2018, which returned average values of 2.62t/m³ for the Main Lode and 2.64t/m³ for the East Lode. A weathering surface interpreted from geological logging was coded into the block model, with all blocks above this surface assigned a bulk density of 1.80t/m³. Blocks located within areas identified as historic mill contamination were assigned a lower bulk density of 1.40t/m³. Figure 8: 2026 MRE block model (unmined) Radio (left) Repeater (right) domains, drill traces and UG development (grey) looking north west Cut-off Grades Cut-off grades have been selected to reflect typical parameters for low strip ratio open pit and narrow vein underground gold mining scenarios. A cut-off grade of 0.5g/t Au has been applied to material within an open pit mining envelope to approximately 50m below surface (around the 300mRL), with a higher cut-off grade of 1.0g/t Au applied to material below this depth, consistent with a potential underground mining scenario. These cut-off grades are considered appropriate for the style of mineralisation and are regarded as suitable for reporting the Mineral Resource. Resource Classification The Mineral Resource has been classified with reference to drillhole spacing, total number of samples, proximity to historic underground development, density of face sampling, demonstrated geological and mineralisation continuity, and the estimation search pass used for each block.

No material has been classified as Measured. Indicated Mineral Resources are defined where drill spacing is approximately 20m, blocks lie within about 15m of underground development, level face sampling is available, geological continuity is high, and blocks are estimated in Pass 1. Inferred Mineral Resources are defined where drill spacing is generally greater than 20m and typically less than 40m, geological continuity is moderate, and blocks are estimated in Pass 2 or Pass 3. No material is left unclassified, as the geological wireframes were limited to within 40m of a drillhole. Material potentially sterilised adjacent to historical mining voids (skins and pillars) has been classified as Inferred so that it is not relied upon for mine design purposes. A previous (2018) Mineral Resource Estimate reported that skins and pillars remained accessible following inspection on re‑entry to the mine. The Mill domain has been classified as Inferred due to the current drill spacing of 10m x 10m and uncertainties in metallurgical characteristics.
