Announcement PDF ASX ANNOUNCEMENT 5 May 2025 ASX: ADD Maiden JORC Resource at London-Victoria Project • Independent Maiden JORC 2012 Inferred Mineral Resource Estimate of 115koz Au defined at the London-Victoria Gold Project. Within this estimate there is a higher-grade mineralised total of 3.14Mt at 1.06g/t Au for 107koz • Defined resources are within a conceptual, shallow open pit no more than 100 m deeper than the existing pit floor • Potential to expand the resource base along strike and at depth, with a shallow RC drilling campaign • London-Victoria Mine saw estimated historical production of 145koz at a head grade of 1.5 g/t Au from mining and processing up to 1996 • Historical gold processing plant located adjacent to the London-Victoria pit Adavale Resources Limited (ASX:ADD) (“Adavale” or the “Company”), is pleased to announce a maiden independent JORC 2012 Inferred Mineral Resource Estimate (MRE) for the London-Victoria deposit of 3.8Mt @ 0.95g/t Au for 115koz Au at a reporting cut-off of 0.25 g/t Au. The board has reviewed the MRE prepared by Derisk Geomining Consultants Pty Ltd (“Derisk”), their resource extension recommendations, as well as the “grade-tonnage” table and have concluded that a cutoff grade of 0.5g/t is optimal for Adavale’s economic assessment of the deposit, which totals 3.14Mt @ 1.06 g/t Au for 107koz. Significant upside remains with mineralisation open along strike and at depth with several historical drill intercepts not included in the resource calculation due to the wide spacing. Adavale is confident that with further shallow drilling from the pit floor, the MRE for the London Victoria deposit can be expanded. The gold mineralisation is contained within a conceptual, shallow open pit no more than 100m deeper than the existing pit floor. Adavale Resources Executive Chairman and CEO, Mr Allan Ritchie, commented: “Adavale are absolutely delighted to announce the release of the maiden JORC MRE, a significant milestone for Adavale, especially within only 3 months since completing the acquisition of the Parkes Project. It comes in the context of recent all-time record high gold prices exceeding AU $5,000 per oz and represents significant value for Adavale. We look forward to being able to commence the recommended resource extension drilling program to significantly increase the maiden resource. London-Victoria’s opportune location, with ample processing capacity in the region provides multiple paths for Adavale to monetise the London-Victoria Resource.” Directors & Officers Adavaleresources ALLAN RITCHIE NIC MATICH Executive Chairman & CEO Non-Executive Director AdavaleL Investors@adavaleresources.com DAVID WARD LEONARD MATH Non-Executive Director CFO & Company Secretary www.adavaleresources.com +61 2 8003 6733 Adavale Resources Limited Level 2, 49 Oxford Close West Leederville, WA, 6007 \ Cross Section 30300 mN Cross Section 30725 mN Cross Section 31350 mN Figure 1: London-Victoria west-east sections with drillholes, resource model, existing open pit and conceptual pit for reporting 2 Cut-off Criterion (g/t Au) Tonnes (Mt) Gold Grade (g/t) Contained Gold (oz) 0.25 3.79 0.95 115,388 0.30 3.76 0.95 115,022 0.35 3.70 0.96 114,467 0.40 3.55 0.99 112,572 0.50 3.14 1.06 106,541 0.60 2.65 1.15 97,899 0.70 2.14 1.27 87,304 0.80 1.75 1.38 78,075 0.90 1.44 1.50 69,469 1.00 1.18 1.63 61,548 Table 1. Grade-tonnes relationship for in situ mineralisation within the conceptual open pit optimisation London Victoria Project – Resource Growth, Opportunities & Next Steps • Mineralisation remains ‘open’ at depth. • Potential to extend the strike length of the mineral resource in both directions by targeting additional known mineralisation. • Subject to further comprehensive information documenting previous activity at the site being made available, a considerable proportion of the Inferred Resource could be converted to an Indicated Resource. • A significant reduction in the operational cut-off criterion to as low as 0.25g/t Au due to higher gold prices. The open pit optimisation used to report the current MRE is based on a conservative gold price of AUD 4,500/oz. • Resource extension drilling program to be developed to maximise the opportunity for a path to future production. • An Exploration Target outlining a range of potential additional tonnes and grade of the deposit outside of the area of the current MRE at London-Victoria is expected soon. Overview of The Parkes Project: A World-Class Geological Setting The Parkes Project comprises four exploration tenements for a total area of 354.15km 2, within the prolific gold and copper-producing Macquarie Arc portion of the Lachlan Fold Belt (NSW). These are prospective for orogenic, epithermal and gold-rich porphyry-style copper-gold deposits. The exploration licences are situated where Early Ordovician-aged Junee-Narromine Volcanic Belt rocks of the western part of the Arc are intersected by the crustal-scale structural corridor of the Lachlan Transverse Zone (“LTZ”). Significantly, the LTZ is host to Tier-1 gold and copper mines, such as Northparkes (5.2Moz Au & 4.4Mt Cu) and Cadia Ridgeway (35.1Moz Au & 7.9Mt Cu) where it intersects Macquarie Arc rocks (Refer Figure 2). The Parkes Project’s most advanced asset is the former London-Victoria Gold Mine which saw estimated historical production by BHP Gold and Hargraves Resources of 145,000 ounces at a head grade of 1.5g/t Au. 3 Figure 2: Map of the central New South Wales Lachlan Fold Belt Background to London-Victoria deposit The London-Victoria Gold Mine has historically been the largest gold producer in the Parkes district and consists of four historically mined deposits from south to north, being the Victoria, Shaws, London and Majors open pits. The earliest mining is reported from the 1870s; 155kg of gold reportedly produced up to the 1950s from both open pit and underground mining. More recently, open pit mining and on-site processing was carried out by BHP Gold and later Hargraves Resources from 1988 to 1996. Geological details obtained from open pit mining reveal that the three highest grade areas, i.e., the London, Shaws and Victoria zones are separated by lower grade zones and that the mined ore bodies were typically poddy as evidenced by the existence of four separate pits. Pervasive shearing is ubiquitous with steeply dipping gold mineralised quartz veins reported as located within plunging zones. Overall, gold mineralisation in the London-Victoria deposit is hosted by an anastomosing shear zone that is highly variable, with the mineralised zone reported to be up to 35m wide in the London zone and individual gold mineralised lenses seen to be overlapping, extending for up to 100m along strike and down dip, and up to 10m wide. These lenses are contained within a sericitecarbonate (including ankerite)-pyrite-quartz alteration zone that is up to 100m wide and 3km long, found east of and adjacent to the north-south striking and steeply east dipping London-Victoria Fault. 4 Summary of London-Victoria Resource Estimate Reporting Criteria Location The London-Victoria gold deposit is located 5.5 km southwest of Parkes in central NSW. It is covered by exploration licence EL7242 that expires in November 2030. The most recent mining and processing at site occurred from 1988 to 1996 on mining Lease ML 1215, which has since expired. The site is on freehold land owned by Westlime Pty Limited (Westlime). Geology and Mineralisation The Parkes Project area is situated within the eastern portion of the Lachlan Fold Belt, which forms part of the Phanerozoic Tasman Orogen of eastern Australia. This district hosts a variety of mineralisation styles, particularly porphyry copper-gold systems, epithermal precious metals, and structurally-controlled gold-copper systems. The London-Victoria deposit lies along the southern portion of the Forbes-Parkes-Peak HillTomingley gold belt. The deposit sits at the contact between Silurian sediments to the west and Ordovician andesitic volcanics and volcaniclastics to the east, separated by the moderate to steeply east-dipping London-Victoria Fault. The site amalgamates four historical workings – from south to north being the Victoria, Shaws, London, and Majors deposits. Gold mineralisation is structurally controlled and is located along the sediment – volcanic contact, along subsidiary shear zones, and penetrates into the eastern volcanics sequence. The main mineralised zone is up to 35 m wide. Two generations of quartz veining have been identified – earlier auriferous veins and late-stage barren metamorphic quartz veins. Gold occurs as inclusions and fracture infill in pyrite and as fine-grained native gold. Surface Costeans and Drilling All of the resource input data used for the current Mineral Resource estimate was collected by two groups – initially Mineral Management and Securities Pty Ltd (MMS) who was subsequently acquired by Alkane Exploration NL (Alkane), then BHP Gold Mines Limited (BHP Gold) who subsequently merged with Newmont Australia to form Newcrest Mining Limited (Newcrest). The resource inputs consist of surface costeans and drilling completed by MMS and Alkane, and drilling completed by BHP Gold and Newcrest. In the immediate vicinity of London-Victoria there are 64 costeans with a total length of 2,954 m, and 382 drillholes totalling 28,332 m recorded in the database. Drilling consists of both reverse circulation (RC) percussion and diamond drilling. Exploration Records MMS and Alkane managed exploration from 1980 through to early-1987 when BHP Gold entered into a joint venture with Alkane and assumed management of the exploration activities. Derisk has sighted no internal technical reports documenting exploration activity and has relied on technical reports submitted to the NSW government that are publicly available. BHP Gold and Newcrest managed exploration, development, and mining operations from early1987 through to late-1993. Derisk has relied on technical reports submitted to the NSW government prior to the grant of ML 1215 that are publicly available. No dedicated reports have been sighted for activities undertaken once ML 1215 was granted. No internal technical reports have been sighted documenting Mineral Resource and Ore Reserve estimates, or Feasibility Study reports; and no internal reports have been sighted documenting mining and processing activities. Hargraves Resources NL acquired the mine in 1993 and operated the site until 1996 when it was closed. Derisk has sighted no internal technical reports documenting exploration or mining activity 5 and there are no public reports in the NSW open access website documenting activities at the ML. Derisk has been advised that Hargraves did not complete any drilling at site. Sampling and Sub-sampling Records sighted by Derisk indicate that costeans, RC chips, and diamond core was sampled on nominal 1 m intervals that were varied to honour geological contacts. Costean channel samples were collected by using an angle grinder to cut two parallel cuts 6 cm apart in the floor of the costean and a 5 cm deep sample was removed between the cuts. Diamond core was mostly cut in half by a diamond saw. No information is available on how the 1 m RC samples were collected and sub-sampled. Sample Preparation and Analyses Records sighted by Derisk indicate that samples were sent to various commercial laboratories for sample preparation and analysis. Samples were crushed to -2 mm, a 500 g split taken then pulverised to -150 mesh. A final split was taken for analysis. Initially, MMS analysed all samples using atomic absorption spectroscopy (AAS) for gold and all elevated samples were reanalysed by fire assay. Details of analytical methods used after MMS are sparse but some records have been sighted that suggest Alkane used an AAS method, and BHP Gold and Newcrest used a fire assay method. Quality Assurance and Quality Control Little documentation has been found describing the QA/QC procedures established by either MMS/Alkane or BHP Gold/Newcrest. Some references have been sighted describing checks made of AAS and fire assay results and the use of external laboratory checks. Modelling and Resource Estimation The London-Victoria Mineral Resource estimate is based on a resource model constructed by Aldebaran Exploration in 2011 that has been reviewed by Derisk in 2025. Derisk has undertaken an independent open pit optimisation to confirm there are reasonable prospects for eventual economic extraction and used the outputs of the optimisation to report the Mineral Resource at an appropriate reporting cut-off as at 31 March 2025. Four mineralisation domains were interpreted that align with lithological and structural controls on the gold mineralisation. These domains were created using a nominal cut-off of 0.3 g/t Au. Samples were composited to 4 m intervals. A statistical analysis of the composites resulted in a decision not to cap gold grades. Gold grades were estimated into a block model with parent cell sizes of 12.5 m (north-south), 4 m (east-west) and 10 m (vertical) with sub-celling to 3.125 m, 1.0 m, and 0.5 m respectively. Gold was estimated using ordinary kriging based on a variographic assessment. The estimate was validated by making visual checks of the model and drillhole data, compilation of swath plots, and a Discrete Gaussian change-of-support check to assess the degree of smoothing in the resource model. Classification Derisk classified all of the Mineral Resource as Inferred. The primary reasons for this decision are: • Lack of documentation supporting the BHP Gold/Newcrest era exploration activity and the inability to validate most of the drilling inputs from this era. 6 • • • No assessment has been undertaken to check the veracity and appropriateness of using the different data inputs to the estimate i.e. surface costeans, reverse circulation (RC) drilling, and diamond drilling of different diameters. No documentation has been provided supporting the DBD assumptions. No documentation is available to reconcile previous mine production against the current resource model. Reporting and Cut-off Criteria Derisk completed a conceptual open pit optimisation based on reasonable assumptions of operating parameters, costs and revenues. Capital expenditure, taxation, depreciation, and the time value of money were not considered. The assumed parameters generated a marginal cut-off criterion of 0.26 g/t Au. Nested shells were created between Revenue Factors of 50% and 150% at 10% intervals. The 100% Revenue Factor optimisation generated a substantial positive cashflow and Derisk used this shell to report the current Mineral Resource at a cut-off criterion of 0.25 g/t Au. Modifying Factors Open pit mining and processing using the carbon-in-pulp process was undertaken at site from 1988 to 1996. The conceptual pit optimisation suggests that expansion of the open pit is potentially viable. It is assumed that mineralisation below the existing open pit can be processed using the same carbon-in-pulp method that was used previously although Derisk notes that recoveries may be lower in fresh mineralisation compared to the oxide mineralisation previously treated. Mineral Resource Mark Berry of Derisk Geomining Consultants is the Competent Person for the Mineral Resource estimate, as defined by the JORC Code. He is not aware of any known environmental, permitting, legal, title, taxation, socio-economic, political, or other relevant factors that could materially affect the London-Victoria Mineral Resource estimate. Table 2 summarises the Inferred London-Victoria Mineral Resource estimate reported using a 0.25 g/t Au cut-off as at 31 March 2025. Table 2. London-Victoria JORC 2012 Mineral Resource Estimate Mineral Resource Category Inferred TOTAL Notes: Tonnes (million) 3.8 3.8 Gold Grade (g/t) 0.95 0.95 Contained Gold (oz) 115,000 115,000 1. All of the Mineral Resource is in situ and reported at a cut-off criterion of 0.25 g/t Au. 2. Resources are reported inside a conceptual pit shell developed using an assumed gold price of AUD 4,500/oz. Table 1 documents the block model at a range of different cut-off criteria inside the 2025 100% RF open pit optimisation shell. For a cut-off criterion up to 0.3 g/t Au, there is little sensitivity to changing cut-off grades. Above a 0.4 g/t cut-off, the model is much more sensitive to cut-off changes.

The Parkes Project Adavale Resources Limited (ASX:ADD) holds a 72.5% interest in the Parkes Gold and Copper Project, consisting of four granted exploration licences that are highly prospective for Au-Cu, primarily due to their location adjacent the giant Northparkes copper-gold mine and encompassing the Ordovician-aged rocks of the Macquarie Arc, within the crustal-scale structure of the Lachlan Transverse Zone (LTZ) that contain both Northparkes and the worldclass Cadia gold-copper Mine. A JORC Inferred Mineral Resource Estimate of 115koz Au defined at the London-Victoria Gold Project. Within this estimate there is a higher-grade mineralised total of 3.14Mt at 1.06g/t Au for 107koz. South Australian Uranium Portfolio Adavale also holds seven granted exploration licences that are prospective for their sedimentary uranium potential within the northern part of the highly- prospective Northern outwash from the Flinders Ranges in South Australia, as well as four exploration licence east of Ceduna on the Eyre Peninsula increasing Adavale’s uranium tenement holdings including to include uranium rights to 4,959km2. The Kabanga Jirani Nickel Project Adavale also holds the Kabanga Jirani Nickel Project, a portfolio of twelve highly prospective granted licences along the Karagwe-Ankolean belt in Tanzania. The nine southernmost licences are proximal to the world class Kabanga Nickel Deposit (87.6Mt @ 2.63% Ni Eq). Adavale holds 100% of all licences except for two licences that are known as the Luhuma-Farm-in, which are held at 65%, adding a further 99km2 and bringing the portfolio to 1,315km2. Adavale’s licences were selected based on their strong geochemical and geophysical signatures from the previous exploration undertaken by BHP. 9 Appendix 1 – JORC Code, 2012 Edition – Table 1 Section 1 Sampling Techniques and Data (Criteria listed in the preceding section also apply to this section) CRITERIA JORC Code Explanation SAMPLING TECHNIQUES • Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. Commentary • • • • • • • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • • • • DRILLING TECHNIQUES ASX Announcement • 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 type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core • • • The London-Victoria resource database comprises channel samples collected from surface costeans and samples from drilling. The data was collected from 1980 to the mid-1990s. Derisk has sighted some technical reports documenting data collection methods but is missing substantive information. The London-Victoria database contains 64 costeans with a total length of 2,954 m, and 382 drillholes totalling 28,332 m. Drillholes are a combination of reverse circulation (RC) and diamond drilling. Costeans were excavated by backhoe to bedrock, then the floor was cleaned by hand and dust blown away using compressed air. Two parallel cuts were made into the floor of the costean approximately 6 cm apart to a depth of 5 cm using a handheld angle grinder. Channel samples were collected between the two cuts using a chisel and hammer. Samples were nominally collected at 1.0 m intervals but were varied to honour geological contacts. No information is available documenting all of the RC drilling but early reports state that some RC drilling was done using a 4½ inch diameter drill bit and a crossover sub located 1 m behind the drill bit. Diamond drillholes were completed using a variety of core diameters; NQ (47.6 mm), HQ (63.5 mm) and PQ (85 mm). Drillholes were sampled on nominal 1 m intervals honouring geological contacts as half-core. Prior to 1980, The London-Victoria deposit had been subject to historical mining by open pit and underground methods. No documentation has been sighted describing measures taken to ensure sample representivity. Derisk notes that some reports document that some drillholes penetrated mining voids and some drillholes experienced significant sample loss. The lack of documentation has influenced the Mineral Resource classification. RC drilling was used to obtain 1 m samples. There is no documentation describing subsampling methods. Diamond drilling was used to obtain nominally 1 m samples, followed by diamond saw cutting lengthwise into half core to obtain sub-samples. Channel samples from costeans were sampled at 1 m intervals, with all of the sample submitted to a commercial laboratory for sample preparation. The London-Victoria database used for this estimate is comprised of RC drilling data, diamond drilling data, and surface channel samples. 10 CRITERIA JORC Code Explanation 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). Commentary • • 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. • • LOGGING SUB-SAMPLING TECHNIQUES AND SAMPLE PREPARATION Records sighted by Derisk show that diamond core was measured and core recovery calculated. There is no documentation denoting if sample recovery in RC drilling was recorded. There is no documentation denoting if or how sample recovery was maximised, except that PQ core drilling was implemented in areas of known poor core recovery. There is no documentation describing measures taken to ensure the 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. • No assessment has been made to determine if a relationship exists between sample recovery and grade and whether sample bias may have occurred. • 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. • All core and RC chips were geologically logged with sufficient detail to support the Mineral Resource estimate. Core was also geotechnically logged. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • • Qualitative logging of geological parameters was accompanied by observational logging of mineral species abundances, which have formed the basis for determining oxidation. No photography has been sighted. • The total length and percentage of the relevant intersections logged. • All channel samples, drill core and RC chips were logged. • If core, whether cut or sawn and whether quarter, half or all core taken. • Initially, core was hand split into half core but was replaced with diamond saw cutting in the early 1980s. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • There is no documentation describing sub-sampling of RC chips. • For all sample types, the nature, quality, and appropriateness of the sample preparation technique. • Channel samples and diamond drill core collected by MMS were subject to primary crushing to -6 mm by jaw crusher then secondary crushing to -2 mm by rolls crusher. A 500 g subsample was collected using a riffle splitter and pulverised to -150 mesh in a ring grinder. A final 100 g subsample was collected using a riffle splitter for analysis. • There is no documentation describing sample preparation methods adopted by Alkane, BHP Gold, or Newcrest. • There is no documentation describing quality control procedures adopted for all sub-sampling stages for any company. • ASX Announcement No information is available documenting all of the RC drilling but early reports state that some RC drilling was done using a 4½ inch diameter drill bit and a crossover sub located 1 m behind the drill bit. Diamond drilling was in NQ, HQ or PQ size. There is no documentation denoting if double or triple tube barrels was used. There is no documentation denoting if any oriented core was collected. Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. 11 CRITERIA JORC Code Explanation 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. • Based on the limited information available on sample sizes, and that reports sighted indicate the gold grain size at London-Victoria is relatively fine, Derisk considers sample sizes were appropriate. • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • MMS reported that samples were analysed using atomic absorption spectroscopy (AAS) for copper, lead and zinc; and AAS for gold and silver. For gold and silver a 20 g sample was digested in aqua-regia and determined by graphite furnace AAS after organic extraction. For samples nominally >1 g/t Au determined by AAS, samples were also analysed using a 25 g sample cut from the 100 g pulverised subsample by fire assay. Where sam
