Announcement PDF 1 ASX Announcement ASX:WIN 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 2 December 2025 HIGH‑GRADE EXTENSIONAL HITS CONFIRM GROWTH AT RADIO GOLD PROJECT Further High-Grade Gold Intercepts at Repeater Deeps and Radio Southern Extension WIN Metals Ltd (ASX: WIN) is pleased to report it has received a further set of strong assays from its recently completed Reverse Circulation (RC) drilling program at the Radio Gold Project, located 38km north of Southern Cross in Western Australia. New intercepts confirming high‑grade mineralisation more than 100m below surface at Repeater and immediately south of existing underground mine workings at Radio. The results demonstrate excellent down‑dip continuity of the Repeater system and highlight clear potential to grow the global Mineral Resource footprint at Radio through both depth and strike extensions. Key results include: • 1m @ 10.11g/t Au from 103m (25RDRC082), Repeater Deeps ~100m below surface, 60m down‑dip from previously reported 1m @ 14.0g/t Au in 25RDRC063. • 1m @ 2.32g/t Au from 125m (25RDRC081), Repeater Deeps, supporting a plunging shoot open to the south‑east. • 2m @ 5.21g/t Au from 102m (25RDRC093), Radio – located ~20m Beyond the current 10 Level development, confirming high‑grade mineralisation continues south beyond the existing mine development. The Repeater intercepts occur at a similar elevation to the base of historic workings at the adjacent Radio Mine, which produced approximately 71,000 ounces of gold at an average grade of 38g/t Au. This correlation supports the interpretation that Repeater represents an along‑strike continuation of the main Radio deposit, with potential to contribute additional high‑grade ounces to the Radio Gold Project resource inventory. Notably, the Repeater mineralisation has not previously been considered in any Mineral Resource Estimate for the Radio Gold Project. Managing Director and CEO, Mr Steve Norregaard commented: “At Repeater, the new 1m @ 10.11g/t Au and 1m @ 2.32g/t Au intercepts, more than 100m below surface and 60m downdip of our earlier 1m @ 14.0g/t Au hit, give us growing confidence in a continuous, high-grade shoot that may underpin a maiden Mineral Resource and meaningful additions to the broader Radio inventory. Equally important is the 2m @ 5.21g/t Au returned ~20m in front of the existing 10 Level development face at Radio Main, which shows that high‑grade mineralisation continues directly along strike of the HIGH‑GRADE EXTENSIONAL HITS CONFIRM GROWTH AT RADIO GOLD PROJECT 2 December 2025 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 current workings supporting our belief in the potential to extend the mine footprint to the south as we move into the next phase of planning.” Drill Results Key results for the Repeater and Radio prospects summarised below with full details outlined in the appendices.

Both intercepts sit approximately 100m below surface and confirm that high‑grade mineralisation persists at depth, supporting the potential to grow the current footprint of the system and Global Mineral Resource of the Radio Gold Project. These new holes are located approximately 60m down‑dip from the previously reported intercept of 1m at 14.0g/t Au in hole 25RDRC0631 , further demonstrating excellent continuity of high‑grade mineralisation at depth. Collectively, these results position the Repeater prospect to support estimation of a maiden Mineral Resource to vertical depths exceeding 100m. Additional RC drill holes targeting a projected, deeper northern plunge returned anomalous grades but intersected the same mineralised host sequence, reinforcing confidence in the geological model. Interpretation of the newdata suggests the main Repeater gold shoot is more likely to plunge to the south, that remains untested by recent drilling. Importantly, these two new intercepts occur at a similar level to the base of historic development at the adjacent Radio mine, which has produced more than 71,000 ounces of gold. On this basis, Repeater is increasingly interpreted as an along‑strike analogue to the main Radio lodes, representing a compelling opportunity to add high‑grade ounces to the Radio Gold Project. Radio Main South Extension Extensional drilling south of the southernmost development at the Radio Main deposit has also returned encouraging results, including 2m at 5.21g/t Au located approximately 20m ahead of the current 10 Level ore drive development. This intercept provides compellingevidence that high‑grade mineralisation continues to the south beyond the limits of historical mine workings and highlights clear potential to extend the mineable footprint along strike. Next Steps • Final assays from grade control and extensional drilling at Radio and Radio South are expected in the coming weeks and will be integrated into updated 3D geological models. • Work is underway to define a maiden Mineral Resource at Repeater and refine the existing Radio and Radio South models to support mine design and scheduling studies. • These technical studies will feed into assessments of near-term restart options for underground mining and potential low-cost open pit opportunities over the largely unmined near surface mineralisation. 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 1 ASX:WIN “Outstanding First Drill Results At Radio Gold Project” Released 5 November 2025 HIGH‑GRADE EXTENSIONAL HITS CONFIRM GROWTH AT RADIO GOLD PROJECT 2 December 2025 5 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 Australia. The site is accessed via the unsealed Mt Jackson Road, providing direct entry to the Project area. Figure 4: Location of Radio Gold Project Goldmining at the RadioGold Project commenced in 1918,producing approximately 71,000 ounces of gold at an impressive average head grade of 38.5g/t Au between 1918 and 1974. Underground operations were re‑established in 2018 using the existing shaft network, with limited development undertaken from the bottom 10 level. More recently, privately held Radio Gold Pty Ltd (NuFortune)established underground accessvia a newportal and completing 330 metres of decline development to the historic second level, enabling the introduction of mechanised mining and a transition from the historic small‑scale, shaft-access mining methods. A shallow open pit was developed to around 25 metres depth in the central zone of the Radio mine; however,most near-surface mineralisation remains unmined, as earlier efforts focused on the high- grade underground lodes. This provides potential for future low-cost open pit production alongside existing underground targets. The Radio mine site remains fully intact and dewatered, with substantial underground infrastructure and equipment in place, positioning the Project for a rapid restart of mining activities.

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 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. Geological 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 0.2–1m 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.

These lodes represent the core of historical production and remain the principal focus for ongoing resource definition. • Radio Repeater – Located immediately north of Radio Main, this zone is interpreted as a geological continuation of the main mineralised system. It is separated from the central zone by a mafic intrusive unit that forms a barren structural partition between the two mineralised corridors. • Radio South – Situated south of the main mineralised trend, this zone consists of multiple gold-bearing lodes that dip steeply (60°– 80°) to the southeast. The lodes display a distinct structural orientation relative to the main Radio system, indicating a separate yet related deformation event controlling gold deposition. Exploration Potential and Further Work The Radio Gold Project presents significant exploration and growth potential, supported by both historical production data and existing geological models. The deposit remains open along strike and at depth, with historical drilling extending to only 260 metres below surface, indicating opportunity for resource expansion within the known lode system. Beyond the central deposits, numerous untested historical workings and structural trends within WIN’s tenure provide additional exploration upside. Priority targets include the Manxman and Queenslander lines of workings, and the along-strike extensions of the Mistletoe and Magpie prospects, all of which are associated with similar quartz vein hosted gold systems typical of the Southern Cross Greenstone Belt. This combination of open mineralisation at depth, extensive near-surface potential, and multiple high-grade historical workings positions Radio as a compelling exploration and development opportunity capable of underpinning future production growth.

Each primary sample was split using an on-rig rotary cone splitter to produce two equal sub-samples in pre-numbered calico bags, each weighing approximately 2–3.5kg. The remainder (reject) was temporarily stored in sample piles at the drill site. Collection methods ensured representative and consistent sampling. Drilling Techniques Drilling was completed using Challenge Drilling’s KWL350 RC rig fitted with a 143mm face-sampling bit and supported by an auxiliary compressor and booster. These methods are appropriate for the local lithology and style of mineralisation. Drill Sample Recovery Sample recovery was recorded by WIN whilst drilling. Recoveries are considered acceptable across the program. Minor losses were observed in the upper metre of some holes due to the fine-grained nature of near-surface material. No correlation was identified between recovery and assay grade. Logging All RC holes were geologically logged for lithology, alteration, weathering, and mineralogy. Logging was performed at one-metre intervals immediately after drilling. Rock chips were sieved, examined, and photographed. All drillholes were logged in full, providing continuous geological coverage. Sub-sampling techniques and sample preparation Primary RC samples were split via the on-rig cyclone splitter to produce representative sub-samples of approximately 3–5kg. Most samples were dry; moist samples were treated using the same technique. All samples were prepared at Bureau Veritas (Canning Vale, WA), where they weredried at 105°C, crushed to <10mm, riffle split, and pulverised to 90% passing 75µm. A 200g pulp was retained for fire assay. Coarse rejects were archived. Sample sizes are appropriate for the mineralisation style and grain size. Quality of assay data and laboratory tests Quality assurance and quality control (QAQC) were maintained through insertion of certified reference materials (CRMs), blanks, and field duplicates at scheduled rates of 5% and 2%, respectively. Samples were assayed by Bureau Veritas via 40g fire assay with AAS finish (detection limit 0.01 ppm Au). QAQC results were reviewed and deemed satisfactory, showing acceptable accuracy and precision. No umpire lab checks have yet been undertaken. Bureau Veritas is NATA-accredited to ISO/IEC 17025 standards. Verification of sampling and assaying Assay results were received from the laboratory in CSV and PDF formats, validated, and imported into WIN’s secure DataShed 5 database (MaxGeo-hosted). Data validation included filter checks and visual review by geological staff. Significant intersections were verified by senior personnel. No data adjustments were made. No twin holes were drilled. Location of data points Collar positions were surveyed using an RTK DGPS (MGA94 Zone 50S). Downhole surveys were collected using an Axis north-seeking gyro tool at collar, 30 m intervals, and end-of-hole, referencing true north.

Positional accuracy and topographic control are considered adequate. Data spacing and distribution Drillhole spacing across the project varies between exploration campaigns, reflecting distinct objectives and stages of project development. Historical drilling was completed on a range of patterns, typically from 20m to 80m along strike and down section, which is considered appropriate for early-stage exploration and delineation of mineralised trends. The current drilling program was designed to infill historical data and enhance geological interpretation. Nominal section spacing includes approximately 10 x 10m for grade control drilling, 20 x 20m for resource definition, and up to 40 x 40m for broader exploration and resource extension. This approach ensures targeted data density proportional to the purpose of each drilling phase. Overall drillhole distribution and sample density are sufficient to establish geological and grade continuity consistent with the requirements for Mineral Resource estimation and m
