The data has revealed multiple gas anomalies associated with uranium which correlate with previous exploration results, providing further confidence in the prospectivity of priority target areas that have been identified for follow-up field work. The results support the Company’s exploration strategy for investigating regional areas surrounding the Oasis deposit with a view to expanding the scale of the project by making new discoveries and defining a maiden Mineral Resource Estimate. The Company has identified nine priority exploration areas where the Sentinel-2 data correlate closely with radiometric and structural targets identified by earlier prospectivity analysis1 . The Sentinel-2 data have also identified an additional seven areas of potential interest due to coincident helium, radon and chlorite anomalism. These areas do not appear to correlate with structural intersections but still coincide with features of interest identified from regional 1 Refer to ASX Announcement Prospectivity Study Confirms Potential For Significant Discovery Upside and Regional Growth At Oasis Uranium Project released 02 October 2025 Highlights  Sentinel-2 multi-spectral data covering the entire exploration area surrounding the Oasis deposit has been acquired and analysed.  Helium and radon (gas) along with chlorite (alteration) anomalies were identified and found to be coincident with previously reported magnetic, radiometric and surface geochemical anomalism.  The gas anomalies coincide with key structural intersections between north-south and northeast-southwest oriented structural sets. Helium and radon are both indicators of uranium mineralisation in many hard-rock uranium deposits.  Chlorite forms a key part of the biotite schist hosting known uranium mineralisation at Oasis and is therefore a potential geochemical indicator for regional exploration.  The combined interplay of structure, radiometrics, geochemistry and multi-spectral anomalism is similar to that observed at the Oasis deposit itself, giving increased confidence in the regional prospectivity and discovery potential within EPM 27565.  Permitting notices have been submitted to allow the Company to commence its next stage of exploration at the Oasis Uranium Project, with an immediate focus on ground-truthing and further development of a strong pipeline of key regional targets. Greenvale Energy Limited ASX Release Page | 2 geophysical data. Together, the combined regional targets strengthen the Company’s belief that the broader Oasis Project offers excellent potential to deliver more intrusive-related uranium discoveries, similar to the Oasis Deposit itself. Greenvale CEO Alex Cheeseman said: "While much of the Company’s exploration effort has so far been focused on or immediately around the Oasis deposit itself, there has also been constant regional target development going on in the background. The addition of the Sentinel-2 multi-spectral data provides another vectoring tool to maximise the opportunity for success when we put teams in the field. “We have invested time and effort to build up a pipeline of quality regional targets ready for the start of our 2026 exploration effort. Beyond the known deposit, the broader Oasis region has been under-explored, so we are excited about the opportunity to make regional discoveries and ultimately build the scale potential at Oasis.” Sentinel-2 Multispectral Imagery In September 2025, the Company engaged an independent contractor to acquire Sentinel-2 imagery from the European Space Agency. Data were acquired covering both EPM27565 and EPM29203 (under application), as shown in Figure 1. The Sentinel-2 system (or Copernicus Sentinel-2) is comprised of two separate satellites, each of which carry high-resolution, wide- ranging, multi-spectral imaging instrumentation. Each unit consists of 13 spectral imaging bands. As the satellites pass over the surface of the Earth, the unit builds detailed maps of element distribution. Figure 1: Project Location Map – Oasis Deposit, EPM27565 (granted) and EPM29203 (under application) Greenvale Energy Limited ASX Release Page | 3 Sentinel-2 provides the mineral exploration sector with another form of time- and cost-efficient, broad-area assessment of element and mineral distribution patterns, using a combination of Visible and Near-Infrared Wavelength (VNIR) and Short Wavelength InfraRed (SWIR) spectral analysis. Imagery collected for Oasis was based on a 10-metre (VNIR) and 20-metre (SWIR) spatial resolution. Figure 2 shows the acquired data overlaying the broader project area, with the heatmap scaled for gas accumulations. Figure 2: Sentinel-2 multispectral imagery over the Oasis Project, including faults and folds interpreted from regional magnetics Incorporation of Results into Prospectivity Analysis The Sentinel-2 data identified anomalous distributions of helium, radon, chlorite, hydrogen, carbon dioxide and methane2 , coincident with previously reported regional radiometrics, airborne magnetics and mapped geology3 . Helium and radon gas are known pathfinders for uranium, often associated with unconformity- style mineralisation (as seen in the Athabasca Basin, Canada). Helium and radon gas present at surface level after seeping upwards along faults and fractures. Helium is one of the daughter products from the U238 decay chain and is therefore a good vector for potential uranium mineralisation. Similarly, chlorite is present within the quartz-biotite schists that host the high- 2 The Oasis Project is situated on a pastoral lease, amongst highly vegetated areas. The hydrogen, methane and carbon dioxide anomalies are therefore more likely to be caused by vegetation and livestock than having any exclusive relationship with uranium mineralisation and have therefore been disregarded in the Company’s analysis. 3 Refer to ASX Announcement Greenvale Acquires Advanced High Grade Oasis Uranium Project released 13 January 2025. Greenvale Energy Limited ASX Release Page | 4 grade mineralisation at the Oasis deposit itself, as well as being a significant mineral in the alteration assemblages adjacent to mineralised zones. The value of the Sentinel-2 data is further enhanced by the coincident helium/radon anomalies over the northernmost radiometric anomaly (refer to anomaly “F” in Figure 3) structural intersection from which rock chip assays collected in mid-2025 returned maximum grades of 187ppm U4 . This northern anomaly, and other similar areas, presented as a zone of strong radiometric response on the uranium channel, with coincident structural complexity inferred from the airborne magnetics. A follow-up rock chip sampling program conducted in mid-2025 ground- truthed these anomalies, confirming their prospectivity as uranium targets by returning assays greater than 50ppm U in some locations. The naturally occurring uranium content of S-type granites in Australia is typically reported to be approximately 12ppm U (Geoscience Australia, 2009), which makes these rock chip results anomalous and very encouraging. Figure 3: Layering of all exploration results (magnetics, radiometrics, structural interpretation, Sentinel-2 multispectral and rockchip/geochemical results 4 Prospectivity Study Confirms Potential For Significant Discovery Upside and Regional Growth At Oasis Uranium Project released 02 October 2025 Greenvale Energy Limited ASX Release Page | 5 Geological setting conducive for further discoveries The combination of geological, geophysical and geochemical anomalism predominantly coincides with mapped occurrences of Mywyn Granite, an S-type granite interpreted to be Mesoproterozoic in age (ca. 1550Ma) intruding into the older country rocks of the Palaeoproterozoic-aged (~1670 – 1695Ma) Einasleigh Metamorphics (Bain & Draper, 1997; Geoscience Australia, 2012; Terra Search, 2024). Analysis of magnetics data had earlier identified multiple, broadly N-S, and NE-SW trending, intersecting structures which, themselves, correlate with the mapped positions of the granite/metamorphic contacts. The Mywyn Granite is one of the potential source rocks for the uranium at Oasis, later disrupted by a younger intermediate and mafic dyke system. The heat from these intrusions either remobilised the uraniferous fluids or transported the fluids further afield. Hydrothermal fluids altered some of the schists, partially resulting in the formation of the chlorite which can be a major reductant for uranium. This layering of geological, geophysical, geochemical and now multispectral, datasets (as seen in Figure 3) significantly enhances the Company’s current geological understanding, providing an excellent vectoring system for uranium exploration in the region. The regional targets shown in Figure 4 are the Company’s immediate focus for upcoming field work. Figure 4: Oasis Project regional exploration target areas in relation to the Oasis deposit Greenvale Energy Limited ASX Release Page | 6 Next Steps The Company has initiated its stakeholder engagement and permitting process to enable field works to commence. Field work is scheduled to begin within Q1 CY2026. Initial fieldwork programs will involve geological mapping, ground surveying with hand-held scintillometers, portable XRF units and potential rock chip sampling/analysis.
