The final batch continues the pattern of broad gold intersections and high-grade mineralisation returned throughout the program, with the principal intercepts again sitting outside the modelled limits of the existing 115koz Mineral Resource Estimate. Highlights include: • 20.95m @ 2.25g/t Au from 278m including: o 10m @ 3.69g/t Au from 278m o 5m @ 1.84g/t Au from 292m (ALD003) • 17m @ 1.38g/t Au from 295m including: o 5m @ 3.24g/t Au from 306m (ALRC081) • 39m @ 1.01g/t Au from 140m including: o 6m @ 2.01g/t Au from 140m; and o 8m @ 1.21g/t Au from 169m (ALRC080) • 7m @ 5.97g/t Au from 202m (ALRC080) With 82 RC holes and 3 diamond drillholes now assayed, Adavale’s entire drillout dataset is available for the upcoming MRE, noting that none of these 85 drillholes are included in the existing London-Victoria Mineral Resource of 3.8Mt @ 0.95g/t Au for 115koz, which was constructed entirely from historical drilling. Adavale Resources Managing Director, Mr. David Ward, commented: “The final 5 drillholes have delivered exactly what we’ve come to expect from the London-Victoria drillout – wide and locally high-grade intercepts sitting outside the current resource envelope. ALD003 in particular, returning 10m @ 3.69g/t Au within a broader 21m zone, reinforces the depth continuity we’ve been building through the program. With the complete assay dataset now available, our focus shifts to geological interpretation and resource estimation. The updated Mineral Resource will provide the first comprehensive measure of what Adavale’s 85-hole program has delivered and an important technical foundation for the next phase of work at London-Victoria.” 2 Figure 1: Plan View of the London Victoria Open Pit displaying all Adavale Drillholes to date (projected to surface) coloured with calculated gold intervals over 0.3g/t Au. 3 Adavale Resources Limited (ASX:ADD) (“Adavale” or the “Company”), an Australian junior explorer/developer focused on gold and copper in the Lachlan Fold Belt of New South Wales, is pleased to report assay results from a further 5 drillholes of the London-Victoria resource drillout, comprising 3 reverse circulation holes and 2 diamond drillholes for 1,717m. Figure 2: Cross Section showing position and gold results for ALD003 relative to the historic London- Victoria Open Pit (Section Line A-A’ displayed in Figure 1) Receipt of these results completes assay reporting for all 82 RC holes and 3 diamond drillholes completed by Adavale at London-Victoria since the project was acquired just 19 months ago, providing the complete dataset required to advance the updated Mineral Resource Estimate. ALD003 was drilled oblique to the line of mineralisation, the section (figure 2) shows a composite high-grade intercept of 20.95m @ 2.25g/t Au from 278m using a 4m internal dilution and includes 10m @ 3.69g/t Au from 278m and 5m @ 1.84g/t Au from 292m. 4 Figure 3: Cross Section showing position and gold results for ALRC080 relative to the historic London- Victoria Open Pit (Section Line B-B’ displayed in Figure 1) ALRC080 - 56m @ 0.84g/t Au is calculated as 4m internal dilution FINAL ASSAYS CONTINUE TO DELIVER GOLD OUTSIDE THE CURRENT MRE All 5 drillholes in the final assay batch returned reportable gold mineralisation, with the principal intersections located outside the modelled limits of the existing London-Victoria Mineral Resource Estimate (“MRE”). Diamond drillhole ALD003 returned: • 10m @ 3.69g/t Au from 278m; and • 6.95m @ 1.39g/t Au from 292m, including 5m @ 1.84g/t Au. ALRC080 returned a broad intersection of 39m @ 1.01g/t Au from 140m, including 6m @ 2.01g/t Au from 140m and 8m @ 1.21g/t Au from 169m. A separate, higher-grade zone returned 8m @ 5.27g/t Au from 202m, including 7m @ 5.97g/t Au. 5 ALRC081 returned 17m @ 1.38g/t Au from 295m, including 5m @ 3.24g/t Au from 306m. Further significant mineralisation was returned in ALD002, including 13m @ 1.18g/t Au from 127m, with a higher-grade interval of 6m @ 1.87g/t Au from 132m. ALRC082 also returned 12m @ 0.63g/t Au from 247m, including 6m @ 0.96g/t Au from 252m. These results provide important additional information on the continuity, geometry and grade distribution of the London-Victoria mineralised system and will be incorporated into the updated geological interpretation and Mineral Resource model. A SIGNIFICANT STEP IN ADAVALE’S EVOLUTION Completion of the 85-hole program and receipt of all outstanding assays represents a significant step in Adavale’s evolution at London-Victoria. The Company is now moving from a phase focused on executing and reporting a systematic resource drill-out to one focused on quantifying the scale and quality of the mineralised system and assessing its potential development pathway. The existing London-Victoria Inferred MRE of 3.8Mt @ 0.95g/t Au for 115koz Au, reported at a 0.25g/t Au cut-off, was constructed entirely from historical drilling. None of the 82 RC holes or 3 diamond drillholes completed by Adavale are included in the existing estimate. The completed drilling program therefore represents a substantial body of new geological, structural and assay information with which to update the London-Victoria resource model. UPDATED MINERAL RESOURCE ESTIMATE With the complete assay dataset now available, Adavale’s immediate focus is the completion of final data validation, geological and structural interpretation, three-dimensional modelling and Mineral Resource estimation. The updated MRE will provide the first comprehensive assessment of the impact of Adavale’s 85- hole drilling program on the tonnes, grade, contained gold and classification of the London-Victoria Mineral Resource. Completion of the updated MRE is targeted for Q3 CY2026. The outcome will establish an important new technical baseline for London-Victoria and assist Adavale in determining the priorities for the next phase of project advancement. SCOPING STUDY TO FOLLOW Following completion of the updated MRE, Adavale intends to advance a Scoping Study for London- Victoria. The Scoping Study will use the updated geological and Mineral Resource models, together with the results of metallurgical testwork, to assess potential mining and processing pathways, development scale, infrastructure requirements and preliminary capital and operating parameters. This work will provide Adavale with an initial technical and economic framework through which to assess the project’s development alternatives and define the additional drilling, metallurgical, environmental and engineering work required to progress London-Victoria. 6 London-Victoria Gold Mine – Next Steps • Brownfields drilling o Systematic “drill out” complete, designed to expand and upgrade existing mineralisation and support Mineral Resource growth. o All drillhole assays received. • Metallurgical testing o Comprehensive metallurgical test work on core samples to assess recoveries and support future development studies. • Scoping study o Early-stage technical and economic assessments to evaluate development pathways and inform project prioritisation. • Geophysical surveys o High-resolution airborne geophysics to refine structural interpretation, improve targeting accuracy and prioritise follow-up drilling. • MRE Update o Expect to complete an update to the MRE by Q3 of CY26 Calarie Gold Mining Licence (ML739) – Next Steps • Magnetic Survey: In the light of the positive magnetics vs gold association at London- Victoria airborne and/or ground-based magnetics will be assessed as a potential tool to assist with targeting. • Detailed Review and Interpretation to refine follow-up drill targets. • RC and/or Diamond Drilling: Post detailed review and interpretation follow-up drilling of high-grade drill results by OMX at the Calarie Gold Mine.

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. • The quality of reverse circulation (RC) percussion drilling is generally medium–high because the method significantly reduces the potential of contamination, unless there is a lot of groundwater or badly broken ground. Consequently, these samples can be representative of the interval drilled and therefore can be used for Mineral Resource estimation. • RC drilling was used to obtain 1m samples collected through a rig mounted cyclone and then using a rig mounted cone splitter to produce an approximately 3kg sample split for assay. • The samples were then dispatched to the Onsite Laboratory Services laboratory in Bendigo. The samples were then crushed and pulverised to produce a 25g charge for fire assay with an AAS (atomic absorption spectroscopy) finish for gold determination, with a 0.01ppm detection limit. • Drill chips were logged by a trained geologist. • Duplicate samples were collected approximately every 20 samples and submitted to the laboratory. Duplicates intervals were selected within zones of visual mineralisation by the onsite geologist. 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). • RC drilling was completed using a 140mm face sampling bit and hammer. • Diamond drilling was completed PQ for the upper oxidised portions and HQ for the remainder 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. • All samples were dry and RC drilling recoveries recorded. • Sample recoveries were considered to be good and within acceptable tolerance for RC drilling. • All diamond drilling recoveries were good. 14 CRITERIA JORC Code Explanation Commentary LOGGING • Whether core and chip samples have been geologically and geotechnically logged to a level of 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. • Systematic geological logging was undertaken onsite at the time of RC drilling, and the diamond holes in Adavale’s yard in Parkes. Data includes: • Collar information including hole depth, coordinates, survey method, survey type, survey date, tenement number, tenement name, prospect name, hole status, date commenced drilling, date completed drilling, pre-collar depth, water depth, bottom of complete oxidation, top of fresh rock. • Nature and extent of weathering. • Nature and extent of lithologies. • Interpretation of relationship between lithologies. • Nature and extent of veining. • Amount and mode of occurrences of ore minerals. • Magnetic susceptibility measurements for every 1m sample. • Both qualitative and quantitative data was collected. • RC chips and diamond half-core were retained in chip trays and stored at Adavale’s yard in Parkes. • Chip and core trays were photographed. 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. • RC samples were collected using a rig mounted cone splitter. • Diamond core was cut using and Almonte auto saw and submitted as half-core. • All of samples collected were dry. • All samples were dried, crushed, and pulverised to 90% passing 75 microns • RC drilling field duplicates were taken approximately every 20 samples. The samples were dried, crushed, and pulverised to 90% passing 75 microns. 15 CRITERIA JORC Code Explanation Commentary 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. • Gold (Au) was determined by 25g fire assay (method Au-PE01S) with a detection limit of 0.01ppm. • Field duplicates were sampled using the same rig mounted cone splitter as the primary samples. The results of the duplicates were within acceptable tolerance from original. • Drill data is compiled and collated and reviewed by senior Adavale staff. • No historic or current drillholes have been twinned. • The strong foliation in the host rocks caused significant deviation in some drillholes as a result some holes have intersected the mineralised horizon close to historic drillhole intersections. All legacy and new drillholes are displayed on the cross-sections and long-sections within the announcement. 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. • Drill data is compiled and collated and reviewed by senior Adavale staff. • No historic or current drillholes have been twinned. • The strong foliation in the host rocks caused significant deviation in some drillholes as a result some holes have intersected the mineralised horizon close to historic drillhole intersections. All legacy and new drillholes are displayed on the cross-sections and long-sections within the announcement. LOCATION OF DATA POINTS • Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control. • Drill collar locations were initially pegged and surveyed using a handheld Garmin GPS with an accuracy of 3-5m. • Drillhole collar and downhole survey co-ordinates are recorded in UTM MGA94 Zone 55S. • All angled holes were downhole surveyed using Reflex GYRO survey tool to produce azimuth and dip readings. Readings were collected typically at a 5m spacing on open hole surveys post completion of drilling the holes. • Topography was determined via drone photogrammetry processed by Drone Deploy and cross checked with the legacy open pit survey.
