The new geophysical data has defined a new interpreted fault structure with correlating magnetic, gravity and radiometric uranium anomalies. The identified structure and anomalies have already been ground-truthed by the Company’s field team, confirming six new target areas within EL33670 (DR15, DR16, DR17, DR21, DR23 and DR24) as shown in Figure 1. The new targets were confirmed by correlating ground-based RS-125, handheld “pXRF” results and airborne radiometric survey data. Samples have been taken and submitted for geochemical assay. Full exploration results, including field-based RS-125/pXRF and independent geochemical assay results received to date are detailed in Appendix 1 with further details in Appendix 2. Cautionary Statement RS-125 and pXRF readings cited in this release are qualitative spot measurements and should not be considered equivalent to laboratory assay results. pXRF/RS- 125 values are subject to variability due to sample heterogeneity, surface effects and Highlights  Project-wide geophysical review completed over EL34157 and EL33670 at the Thunderball Uranium Project in the Northern Territory, in parallel with ongoing field mapping and sampling programs.  Various geophysical datasets were merged and assessed, revealing a large-scale, NW-SE trending fault structure running parallel to the geological contact between the Pine Creek Orogen and overlying sedimentary basins.  Field teams have now ground-truthed the geophysical results and confirmed six new project-level targets, with samples collected and sent for independent chemical analysis – with results pending.  Ongoing field work is focused on a recently identified fault splay adjacent to the Spectre Prospect, further developing the structural model and increasing understanding of potential new fluid transport traps similar to the high-grade Thunderball Deposit.  Greenvale continues to grow and develop its uranium exploration pipeline in the Northern Territory, with grass-roots exploration continuing to deliver positive results.  Recently received initial geochemical results have confirmed uranium anomalism at the Powers, Wildcard South and Spectre Prospects – with permitting underway for future drill testing.

They are intended only as an indication of elemental presence and relative abundance and are not representative of bulk grade or mineralisation. Definitive results will be confirmed through independent laboratory chemical assay. Figure 1 – Uranium specific exploration target areas and confirmed Prospects within the Thunderball Uranium Project Greenvale Managing Director Alex Cheeseman said: "Following the outstanding results generated by our recent field work programs across our northern tenement, EL34157, this latest geophysical review and field-based follow-up has generated a series of exciting new targets in the southern tenement, EL33670. “The Greenvale field team is successfully expanding our exploration target pipeline across the entire land package, which is an excellent result. “On-ground exploration is continuing across the remaining anomalies, with the aim of testing as many of these as possible before the build up to the Wet Season starts. “This early-stage, grass-roots target development work is incredibly important as we systematically test areas of interest and build up a pipeline of opportunities ready for drill testing.” Independent Geophysical Data Review An independent review of publicly available state-wide, region-wide and Company-procured data was completed by Arrow Geoscience, with the objective of identifying additional structures that might influence mineralisation processes within the Project area. The data packages comprised merged airborne magnetics, radiometrics, gravity and electromagnetics data sourced from the Northern Territory Geological Survey (NTGS), acquired Greenvale Energy Limited ASX Release Page | 3 on 400 metre-spaced flight lines, and merged together with various additional open-file, historical, company-based geophysical surveys that were flown on 200 metre-spaced flight lines. These data also included the Airborne Magnetics-Radiometrics (AMR) surveys acquired by Greenvale Energy between 20241 and 20252 . The results highlighted a major, NW-SE trending fault structure within the central portion of EL33670. Airborne radiometric anomalies were also identified on the north-eastern side (hangingwall) of the interpreted fault structure, showing good correlation with identified magnetic anomalies in this part of the project area as seen in Figure 2. Figure 2 – Merged airborne magnetics survey data, geological interpretations and coincident radiometric targets confirmed within EL33670 The orientation of the structure matches the orientation of the geological contact between the polymetallic Pine Creek Orogen and the overlying Daly and Birrindudu Basins. This newly identified structure is important because it may represent a potential graben (a block of crust that has been dropped by faulting during basin formation). The formation of a graben can create space for uranium-rich and polymetallic fluids to enter the overlying sediments from the bedrock below the basins. There are three major, known, regional-scale fault orientations within the Project area, with the newly identified structure enhancing this structural complexity and creating potential for additional mineralisation traps. Field Investigations Ongoing The newly recognised radiometric anomalies were added to the suite of project-level targets to be investigated by the Company’s field team. 1 Refer to ASX Announcement Uranium anomalism confirmed by airborne surveys in the NT released 19 November 2024 2 Refer to ASX Announcement Completion of Airborne Survey Across NT Uranium Projects released 27 May 2025 Greenvale Energy Limited ASX Release Page | 4 Targets DR15, DR16, DR17, DR21, DR23 and DR24 showed consistent high anomalism up to 17ppm eU relative to a natural background of ~4ppm eU. A heat map of the field results can be seen in Figure 33 . Geologically, these anomalies were also found to coincide with mapped limestones and minor granite outcrops, although exposure at surface was infrequent. Field investigations in this area are continuing, with new geological information being added to the Company’s exploration model as the program progresses. Figure 3 – Gridded RS-125 results (eU ppm) and confirmed targets for future follow-up within EL33670 Field results validated through geochemical assay The first batch of geochemical assays have now been returned, with results confirming uranium anomalism in the sediments of the Daly Basin. Peak results up to 51ppm U were observed from the Wildcard South Prospect, with chemical assay results showing consistent correlation with field results from the RS-125 and pXRF spectrometers. The chemical assays returned from the Powers Prospect considered anomalous given the background values of only 3ppm U and the geological context of the prospect. Geological context is important with these results, as the lack of outcrop at Powers is a strong indicator of a thicker package of cover sediments. The low-level uranium assays are still showing good correlation with the geophysical results at surface, which warrants further investigation of the Prospect area. Anomalous breccia confirmed as fault splay off Hayes Creek Fault The Hayes Creek Fault is known as a major, large-scale, NE-SW trending, structural system associated with high-grade uranium deposits such as Thunderball. Historical and government- sourced geological mapping has also revealed smaller-scale faults that appear to splay off the 3 Refer to Cautionary Statement on page 1 regarding field-based results from RS-125 and pXRF. Greenvale Energy Limited ASX Release Page | 5 Hayes Creek Fault on a NNE-SSW orientation, eventually intersecting the main structure. One example is the Bella Rosa Trend, which includes the historical Bella Rose uranium deposit. These splays form a large structural zone that intersects the geological boundaries between the Pine Creek Orogen, Birrindudu Basin and Daly Basin. This is significant because this zone creates several openings in the polymetallic rocks of the Pine Creek Orogen metasediments, granites and volcanics, acting as another large-scale transport pathway for uranium-bearing fluids to enter the overlying, younger, basin sediments. In July 2026, an outcrop of breccia was discovered approximately 1.1km south-east of the Spectre Prospect4 . Structural data collected at the time suggested that this breccia may have been one of the southern fault splays coming off the Hayes Creek Fault, orientated on a strike of 040 (approximately NNE-SSW). Indicative results from the RS-125 and pXRF (27ppm eU and 21ppm U, respectively) strongly indicated that the breccia was anomalous in uranium. Chemical assay results show good correlation with both instruments, confirming uranium mineralisation with values up to 21ppm U from the first outcrop of breccia. In September 2026, a second outcrop of breccia was discovered to the north-northeast of the first outcrop. Again, RS-125 and pXRF results indicated uranium anomalism with maximum readings of 9.9ppm eU and 39ppm eU, respectively. It is now interpreted that the breccia is part of a fault splay coming into the main Hayes Creek Fault, with the point of intersection situated approximately 1.5km east of the Spectre Prospect as seen in Figure 4. Further samples have been collected from these exposures and are being processed for independent chemical assay. With chemical assay results pending, the confirmation of uranium-anomalous breccia along a newly interpreted fault splay is significant because it identifies a potential geological connection to the Hayes Creek Fault, which is associated with high-grade uranium mineralisation at the Thunderball deposit. The discovery of multiple anomalous outcrops along the structure strengthens the potential for further mineralisation and provides Greenvale with a compelling, clearly defined corridor for continued exploration. Next Steps Field investigation of the remaining radiometric anomalies is proceeding, with Greenvale’s field team continuing to assess each area with the RS-125 and pXRF spectrometers and collecting field samples from areas deemed worthy of further investigation. Permitting and approvals are also progressing, with the Company permitting a number of identified prospects to allow flexibility to undertake initial drill testing of a range of targets. Additional fieldwork is planned for ground investigations of radiometric anomalies at the Elkedra- Henbury Project. The field work will involve similar geological mapping, geophysical assessment with the RS-125 and pXRF, and collection of physical samples as completed over the past few months at the Thunderball Project. 4 Refer to ASX Announcement Initial Fieldwork Confirms New Priority Prospects At The Thunderball Uranium Project released 03 August 2026 Greenvale Energy Limited ASX Release Page | 6 Figure 4 – Gridded RS-125 results (eU ppm) over the Spectre Prospect and surrounding area Authorised for release This announcement has been approved for release by the Board of Directors.
