Greenvale Energy Limited ASX Release Page | 2 25GRV007 – 10) and also indicating potential for additional mineralised structures west of the known deposit (drill-holes 25GRV011 and 25GRV012). The results have, collectively, allowed the Company to confirm a wide range of compelling growth exploration targets for 2026. A summary of key results from the drilling program can be seen in Table 1, detailed exploration results are provided in Appendix 1, 2 and 3. Greenvale CEO Alex Cheeseman said: “2025 was our first year of exploration at the Oasis Uranium Project and the Company’s first-time drilling for uranium. Our initial field season has exceeded expectations in all areas. We are pleased with the high standards and operational proficiency of our personnel and contractors having run an efficient and effective program that has delivered excellent results. “The early results from the program delivered some standout intercepts, and these final assays from drill-holes 25GRV007 to 25GRV010 confirm our geological model, with the assays from drill- holes 25GRV011 and 25GRV012 indicating that there is still excellent potential to discover high- grade uranium mineralisation in areas outside of the main Oasis deposit. “Building geological models and exploration strategies is an iterative process which is continually enhanced with each successive field activity. A key opportunity for Greenvale is to take the detailed knowledge we have at the Oasis deposit and apply it to our regional targets within EPM27565. “We are excited to re-commence field work in the New Year as we strive to make further uranium discoveries, define mineral resources and build our portfolio against the backdrop of strong industry tailwinds.” Table 1 – Standout Assays from the Oasis Uranium Project Hole ID Chemical Assay Intercepts Comments From (m) To (m) Thickness (m) Avg.

Details of the drill-holes and their respective significant intercepts are provided in Appendix 1 and 2. Chemical assays were received from the mineralised zone in holes 25GRV007, 25GRV008, 25GRV009, 25GRV010, 25GRV011 and 25GRV012 (refer Figure 1). The results further confirmed earlier interpretations – that high-grade uranium mineralisation is hosted within structurally controlled, deformed granite intrusives and a chlorite-biotite schist that forms a structural and metamorphic contact between the granite and granitic gneiss (high-grade metamorphics). As previously reported, the main Oasis Shear strikes approximately north-south, with a 60-70° dip to the west. The interplay of structures and mafic (dolerite) dykes led to the interpretation that Oasis is likely to be an intrusive-style uranium deposit, with the mafic intrusives providing the heat required to mobilise uranium-rich fluids out of the granites and into the structural zones. Holes 25GRV011 and 25GRV012 are located on the western side of the deposit (Figure 2). Each hole returned only minor intercepts, highlighted when the lower grade cut-off of 200ppm U3O8 was applied. Hole 25GRV011 contained a best intercept of 0.5m @ 171ppm U3O8, while 25GRV012 returned an intercept of 1m @ 429ppm U3O8. Given the emerging complexity of the Oasis deposit, the consistent presence of uranium in these later drill holes could be indicators of higher-grade mineralisation and therefore represent target areas to be further investigated. Samples collected from the RC pre-collar cuttings in each drill-hole are also being assayed to build a geochemical profile through the hangingwall material above the mineralised shear zone. This information will help gauge pathfinder elements and alteration assemblages, both very useful as geochemical vectors during regional exploration. Preliminary review of results received to date from these pre-collar sections suggest the presence of elevated vanadium, thorium, yttrium and lanthanum which may be related to, and present as haloes around, the uranium mineralisation. Work is ongoing and interpretations will develop further as more results are received. Overall, Greenvale’s maiden drilling campaign at Oasis has been highly successful. A total of 12 holes and 1,804.2 metres were drilled between July and September 2025, consisting of Reverse Circulation (RC) pre-collars and diamond core (DD) tails. High-grade mineralisation was confirmed in the majority of the drill-holes, with historically- delineated deposit boundaries significantly expanded (refer Figure 2). The mineralisation remains open, both along-strike and down-dip of the known Oasis Shear.

Greenvale Energy Limited ASX Release Page | 5 Figure 2 – Updated long-section of the Oasis Uranium Deposit, looking West, mineralisation remains open at depth Trenching Program Completed With all field works now complete, samples collected from the trenching program have been dispatched and are currently being analysed, with results expected in the coming weeks. The Company anticipates some reporting delays due to the availability of contractors during the Christmas/New Year period. All results will be released to market as and when they become available. Next Stage of Work – 2026 Since exploration began at Oasis in the early 1970s1 , all activities have centred predominantly on developing the deposit itself. Regional exploration has been very minimal, with historical soil, stream sediment and rock chip sampling completed over selected areas, with only some of those samples being assayed for uranium and no follow-up exploratory drilling. For this reason, geological understanding of mineralisation potential is limited for the regional areas surrounding Oasis. One of the best ways to address this problem is to build geological models from drilled, delineated, mineralisation zones (i.e., Oasis), determine correlatable patterns between these mineralised bodies and different datasets (e.g., geophysics and 1 Refer to ASX Announcement Oasis Uranium Prospectivity Report released 02 October 2025 Greenvale Energy Limited ASX Release Page | 6 geochemistry), and then expand that pattern recognition into regional areas that have the same geoscientific datasets but little to no drilling. This approach will shape Greenvale’s exploration efforts for the first part of 2026. Once assays have been received, the next phase of work involves collating all of the drilling and trenching data into the ongoing geological and structural models, in order to better understand the mechanisms involved in forming the uranium mineralisation at the Oasis Deposit. Greenvale is looking to initiate early-stage, geological reconnaissance and mapping at the beginning of the New Year – subject to weather and ground conditions. The information gained will be fed back into the developing prospectivity analyses and drill target generation work, with a view to test these targets during the 2026 field season. Another successful year in 2026 will likely lead to the ability for the Company to prepare and define a maiden mineral resource estimate (MRE) for the Oasis uranium Project.

Criteria JORC Code explanation Commentary Sampling techniques • Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the mineralsunder investigation, such as down holegamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. Drill samples were taken from the core section of diamond drill holes, pre-collared with Reverse Circulation percussion drilling (RC). Triple tube HQ diamond drilling was utilised, half core samples were collected on a 1m basis. Samples were photographed, half-cored, and despatched to an external lab by an external contractor. A total of 12 holes were completed for 1,804.2 drilled metres. Trench sampling involved the excavation of six trenches, with lengths varying between 100 and 152m and a total 774.5m excavated. Each trench was 1.2 metres wide, variable depths between 1.6 and 2.5 metres deep. Depths were dependent on the weathering profile, and the thickness of cover sediments on fresh bedrock. Each trench was radiometrically surveyed with a handheld scintillometer. Readings were taken every 1 – 2 metres along the wall of the trench, with spacings closing in to 0.5 metre if readings increased over 500 counts per second (cps). Samples were collected along cut channels, with 2 - 4metre composites collected over areas of background radiometric values (between 200 – 400 cps). In zones of anomalous radiometric response (i.e., more than 500cps), sample intervals were reduced to 1- and 0.5-metre widths. Drilling techniques • Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). 9 core holes were drilled at -60°, 2 at 70° and 1 drilled at -80° from surface using reverse circulation drilling until core point was reached. Then HQ drilling methods employed, using triple tube chrome barrel and orientation tool. Hole depths ranged from 66.33m to 309.85m. Drill sample recovery • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. Chip samples were collected at approximately 1m intervals. All chip samples were geologically logged and photographed. All drill samples were collected and stored in sample trays at Terra Search storage facility. Core recovery was recorded for all drill runs and documented in a Geotechnical log for each hole. The Triple Tube technology and procedure ensured core recoveries were excellent throughout the hole. Core was marked up in metre lengths and reconciled with drillers core blocks. An orientation line was drawn on the core. Core sampling was undertaken by an experienced operator who ensured that half-core Greenvale Energy Limited ASX Release Page | 12 Criteria JORC Code explanation Commentary was sawn up with one side consistently sent for analysis and the other side was consistently retained for archive purposes. The orientation line was consistently preserved. An unbiased, consistent half-core section was submitted for the entire hole, based on continuous 1m sampling. The entire half core section was crushed at the lab and then split, the representative subsample was then finely ground, and a representative unbiased sample was extracted for further analysis. Logging • Whether core and chip samples have been geologically and geotechnically logged to a levelof detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. Chip samples were collected every metre, geologically logged and photographed. All core was collected, measured, geologically logged and photographed. Geological logging was carried out by well-trained/experienced geologist and data entered via a well-developed logging system designed to capture descriptive geology, coded geology and quantifiable geology. All logs were checked for consistency by the Principal Geologist. Data captured through Excel spread sheets and Explorer 3 Relational Data Base Management System. A geotechnical log was prepared. Logging was qualitative in nature. A detailed log was described based on visual observations. A comprehensive Core photograph catalogue was completed with full core dry, full core wet and half core wet photos taken of all cores. The entire length of all drill holes has been geologically logged. Drill holes 25GRV01 – 12 were geophysically logged with the following suite of tools run including Density, Calliper, Verticality/Deviation, Gamma, Spectral Gamma and ATV Acoustic Scanner. The remaining drill holes will be geophysically logged at the end of the drill program. The calibration of the geophysical tools was conducted by the geophysical logging company engaged in the project at the time. Logging of the trench faces was also qualitative in nature. A detailed log was described based on visual observations. A comprehensive section profile was drawn from the wall of each trench. The entire length of each trench has been geologically logged. Greenvale Energy Limited ASX Release Page | 13 Criteria JORC Code explanation Commentary Sub-sampling techniques and sample preparation • If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in- situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. Half-core samples were sawn up on a diamond saw on a metre basis at Terra Search facility in Townsville, QLD and submitted to Intertek Adelaide for preparation and analysis. The above techniques are of a high quality, and appropriate for the nature of mineralisation anticipated. Radiometric data is collected every metre of the RC and core holes to be checked and correlated against any lab data for U, Th, K. Similarly portable XRF (PXRF) data is collected on a 1m basis from RC bulk sample and from 3m drill cuttings (sludge samples) from the core sections. The latter sampling provides a qualitative check on U, Th, K contents on a broader 3m scale. In addition, downhole radiometric probe data has been collected which is providing additional validation of the appropriateness of sample size. Trench sampling has been undertaken with the use of a track-mounted excavator to dig the trenches. The sampling procedure involves the use of a field hammer, PVC split, plastic sheets and calico bags. The hammer is used to chip samples out of the trench face, with material falling into the PVC split below. Once the sample has been collected from the interval, it is bagged into a pre-marked calico bag. In all sample cases, the standard 2kg -5kg sample is more than appropriate for the grainsize of the rock-types and the sub-microscopic uranium minerals and sulphide grainsize. The sample sizes are considered to be appropriate to represent the style of the mineralisation, the thickness and consistency of the intersections. Quality of assay data and laboratory tests • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. Preparation of rock chip and core samples involves crushing splitting and grinding at Intertek/Genalysis lab Townsville. Higher grade uranium assays are analysed at Intertek in Adelaide. The total amount of economic metals and pathfinder elements tied up in sulphides and oxides such as U,Th,Cu, Pb, Zn, Ag, As, Mo, Bi, S is captured by the 4-acid digest method ICP finish. Mass spectrometry (MS) ensures low level detection and REE are also captured. This is regarded as a total digest method and is checked against QA-QC procedures which also employ these total techniques. Major elements which are present in silicates, such as K, Ca, Fe, Ti, Al, Mg are also digested by the 4-acid digest Total method. The techniques are entirely appropriate for a schistose, micaceous mineralised structure such as Oasis, hosted in primarily a granitic / metamorphic terrane. The economically important elements in these deposits are contained in both Greenvale Energy Limited ASX Release Page | 14 Criteria JORC Code explanation Commentary resistate minerals and sulphides which are almost entirely liberated by 4 acid digest, all gold is determined with a classic fire assay. Samples were assayed for gold using the 50g fire assay method. Downhole probing was completed by a spectral gamma tool which is a down-hole logging device that measures natural radiation in the rocks to help identify their mineral content. By analysing the energy spectrum of gamma rays, the tool can distinguish between key elements such as uranium, potassium and thorium, but still only provides an equivalent uranium value. This method provides a reliable way to estimate uranium content in drill holes, which should then be confirmed by chemical assays, and may give early indications of mineralisation. Radiometric disequilibrium occurs when the uranium parent isotope is gained or lost during geological processes, disrupting the balance between parent and daughter isotopes. Historical work at Oasis indicates this is not a significant issue, with good correlation reported between chemical and radiometric grades. Recent drilling results from holes 25GRV01 and 25GRV02 are providing good confirmation that this is true. QAQC samples are monitored on a batch‐by‐batch basis, Terra Search has well established sampling protocols including blanks (both coarse & pulped), certified reference material (CRM standards) Terra Search quality control included determinationson certified OREAS samples interspersed at regular intervals through the sample suite of the commercial laboratory batch. Standards are checked on receipt of results. Within the drill core results that have been returned to date are found to be within acceptable tolerances. Laboratory assay results for these quality control samples are within 5% of accepted values. Verification of sampling and assaying • The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. Sample intervals to be assigned a unique sample identification number prior to sample despatch. Significant intersections from the drilling were verified by Terra Search Pty Ltd, independent geological consultants who geologically supervised the drilling. Validation is checked by comparing assay results with logged mineralogical intervals that are diagnostic of the mineralization e.g. chlorite schist, with quartz veins, minor sulphide and accompanied by high radiometric counts.
