Mr Mathew Watkins Company Secretary Aureka Limited A S X : AK A BRINGING VICTORIA'S GOLD TO LIFE 1 ASX ANNOUNCEMENT 13 JUNE 2025 ST ARNAUD MAIDEN JORC RESOURCE INCREASES AUREKA’S GLOBAL GOLD INVENTORY AND EXPLORATION TARGET RANGE HIGHLIGHTS  Aureka’s historic 120 drill holes at the Comstock pit St Arnaud yields Maiden Inferred JORC Resource, and increases Aureka’s global JORC Resources by 19% from 304koz to over 360koz and adds an additional Exploration Target range to its portfolio.  St Arnaud Comstock Mineral Resource Estimate 1.45Mt at 1.2g/t Au for 56,500 oz gold within historically mined open pit. In addition, an Exploration Target around the Resource has been defined for 112,000 oz to 116,000 oz gold.  Potential for gold mineralisation to extend at depth and along strike of open pit – this shall be tested by Aureka’s current drill program at Comstock. Mining operations ceased in the 1990s with high grades produced up to 50 g/t per tonne.  The historic mine is located within a fenced off public reserve and may lend itself to a more favourable permitting process compared to greenfield sites. A number of third-party owned processing mills are located within trucking distance of Comstock.  Aureka is currently undertaking diamond drilling at Comstock with potential to add to this maiden inventory figure later in the year. Aureka Limited (ASX: AKA, “Aureka”, “the Company”) is pleased to announce the Maiden JORC Resource and Exploration Target for the Comstock Prospect within the St Arnaud Project area (AKA 100% owned). The St Arnaud – Comstock Prospect is located in Western Victoria, 65km northeast of Stawell and 90km west of Bendigo, and was last mined in the 1990s. A maiden JORC Mineral Resource of 1.45M tonnes at 1.21g/t Au for 56,500 oz gold has been determined and additionally, an exploration target around the inferred resource has been estimated to range between 3.0Mt and 3.5Mt, at grades 1.2g/t to 1.0g/t resulting in an exploration target range estimate of 112koz to 116koz of gold, and potentially economic amounts of silver at a grades of 1.9g/t to 2.02g/t Ag for total of 195koz to 214koz silver A S X : AK A BRINGING VICTORIA'S GOLD TO LIFE 2 13 JUNE 2025 St Arnaud increases Aureka global gold inventory The additional JORC Resource and Exploration Target results in a meaningful lift in Aureka’s already substantial gold inventory that until now was made up of only the Irvine Project in the Stawell Corridor. The addition of the St Arnaud Comstock MRE increases the global gold inventory of Aureka’s project portfolio by 19% from 304,300 oz to 360,800 oz, and adds a further Exploration Target has been defined for 112,000 oz to 116,000 oz gold, which diversifies the Company’s gold production potential by adding another project with potentially economic inventory of gold.

A S X : AK A BRINGING VICTORIA'S GOLD TO LIFE 3 13 JUNE 2025 Early JORC declaration demonstrates underlying value within Aureka’s large portfolio When Aureka resumed activities in late 2024, it did so with one of Victoria’s largest portfolios of advance stage exploration and pre-development gold projects. The initiative for Aureka to commission and deliver the St Arnaud Comstock MRE on existing data in the current favourable gold price environment, demonstrates the determination to fully exploit the hidden pockets of value within the project portfolio. Current and most recent drill programs at Comstock, St Arnaud As announced on the 10th of April, Aureka has recently commenced a diamond drilling program at St Arnaud. An initial 4 hole, 1,400 metre program is underway along strike and adjacent to the old Comstock pit with drilling on schedule and progressing as planned. If successful, these initial drill holes and any other follow up programs over coming months may enable an update of the Maiden JORC Resource and Exploration Target for the Comstock Prospect. Figure 1: Current drilling program at Comstock St Arnaud. The most recent program prior to the 2025 campaign was a 17-hole program reported on 21 January 2022 that included highlights (ASX Release: Broad gold zones in first holes on Nelson Line at St Arnaud 21 January 2022):  1.0 metre at 13.9 grams per tonnes (g/t) gold within a broader zone of 25.3 metres at 1.7 g/t gold from 157.7m (NED008)  4.6 metres at 3.2 g/t gold & 26.9 g/t silver from 194m (NED009)  4.0 metres at 2.4 g/t gold & 15.9 g/t silver from 165.8m (NED010)  8.3 metres at 2.1 g/t gold & 1.6 g/t silver from 266.7m (NED011) A S X : AK A BRINGING VICTORIA'S GOLD TO LIFE 4 13 JUNE 2025 "It is very pleasing, in this strong gold price environment, to be able to define an inferred JORC Resource and Exploration Target for the previously mined open pit at Comstock so soon after we have resumed activities. This has added to our inferred JORC inventory with an additional exploration target across our projects, and demonstrates our ability to deliver value for shareholders from within our portfolio of advanced stage exploration projects. As announced on 10 April 2025, we have also recently begun drilling at St Arnaud to uncover more of the potential gold that lies within the Comstock pit area. If these and future drill holes prove successful, we look forward to potentially adding to this maiden JORC Resource and Exploration Target later in the year. " - James Gurry, Managing Director Initial Mineral Resource at St Arnaud – Comstock Prospect Aureka is pleased to announce a Maiden JORC Resource and Exploration Target for the Comstock Prospect at the St Arnaud Gold Project (100% Aureka). Earlier in 2025, Aureka recognised the extent of previous drilling data available which, in the current economic climate, has been sufficient to determine a maiden JORC Mineral Resource Estimate and Exploration Target for the prospect just when the market is looking for deposits with near term production potential. Comprising drilling data from air core (AC), reverse circulation (RC) and included 27 diamond drill (DD) holes. The most recent drilling was reported in January 2022 after drilling on the southern and northern edges of the Comstock pit (17 diamond drill holes). In April 2025 Aureka engaged a third-party consultant to undertake a Mineral Resource Estimation (MRE). Resource estimation has been completed on the interpreted mineralised areas and the ore contained within the historically mined Comstock Pit has been depleted, Results of the model based on the mineralised trends are outlined below: Table 3 - Comstock Mineral Resources Cut-Off Prospect Gold Inferred Tonnes (g/t) Comstock (St >0.5 Gold Grade Gold Grade Silver (g/t) Ounces (g/t) (oz) silver 1,450,000 1.21 56,500 2.14 100,00 Arnaud) The preceding statements of Mineral Resources conforms to the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code) 2012 Edition.

A S X : AK A BRINGING VICTORIA'S GOLD TO LIFE 9 13 JUNE 2025 Information Required By Listing Rule 5.8.1 Geology and Geological Interpretation St Arnaud district sits on the eastern margin of the Stawell Geological zone of the Lachlan Orogen. The Saint Arnaud Group metasediments are unfossiliferous, quartz rich turbidites and are assumed to be Cambro-Ordovician in age. The Comstock prospect is located within the historic St Arnaud Goldfields along the Nelson line of reef and is situated ~2km north of the township of St Arnaud. The local geology consists of a package of tightly folded turbidites with distinct shale and sandstone layers of varying thicknesses. The area is dominated by a NNW trending, west dipping fault/shear zone known as the Comstock Shear. The shear zone is interpreted to lie within the hinge zone of a large-scale syncline and is confined by a wide, shale dominant zone of sediments. Shale directly adjacent to the shear zone tends to be highly carbonaceous and very dark grey to black in colour. Course euhedral pyrite crystals seem to be syngenetic to this carbon rich zone of fine sediments, quartz veining is associated with gold mineralisation and is massive to stylolitic in texture. Primary gold mineralisation at St Arnaud is hosted within quartz veins which are structurally controlled within very complex structural domains associated with folding and NNW trending, west dipping thrust faults. Gold mineralisation is hosted by quartz reef systems within brittle fractures and faults and can extend from a few metres long to a few kilometres along strike but usually a few hundred metres. These NNW trending reefs have steep, southerly pitching gold shoots. The mineralisation has a base metal signature of Au + As + Ag + Pb. In historical records, the gold ore was characterised by a relatively high sulphide content up to 5% pyrite, chalcopyrite, arsenopyrite, galena and silver. Most of the mines stopped at the oxide-sulphide interface due to reduced grade and poor recoveries from sulphide ores. The quartz reef systems can extend for a few metres to a few kilometres along strike but are usually a few hundred metres strike length. There appears to be an association with green-black carbonaceous shales and higher gold grades. Sampling and Sub-sampling Techniques Air Core holes are routinely sampled at 1 m intervals downhole directly from a rig mounted cyclone. Subsamples for assaying are generated from the 1 m preserved samples and have been prepared at the drill site by a spear sampling method, based on logged geology and mineralisation intervals. Sub-samples are taken at 1m intervals through the mineralised zone or as composites of 2m intervals through the rest of the hole. Reverse Circulation samples were collected every two metres through a cyclone and automatically split. The bulk sample was directed to a polypropylene bag and an assay sample was directed into a calico bag. Each two-metre interval drilled provided approximately 24 kg. (average) to the bulk sample bag and 2 kg. (average) to the assay sample bag. Samples for assay were bagged, numbered, and sealed on site. Diamond core samples are selected on geological intervals varying from 0.3m to 1.3m in length. All drill core is routinely half core sampled (usually on the right of the marked orientation line) with a diamond saw. A S X : AK A BRINGING VICTORIA'S GOLD TO LIFE 10 13 JUNE 2025 Drilling Techniques Air Core (AC) Drilling AC drilling has been carried out using a Wallis Mantis 80 AC rig mounted on a Toyota Landcruiser base. The AC rig used a 3.5” blade bit to refusal, generally just below the fresh rock interface. Reverse Circulation Drilling RC drilling has been conducted using a track-mounted drill rig; 400psi 900cfm compressor and booster; auxiliary compressor where dictated by water in-flows. The RC rig used a 4” diameter RC hammer with 110mm button bit to progress the hole to design depth or where groundwater inflows compromise sample quality. Diamond Core Drilling Diamond drilling has been conducted using Deepcore track-mounted LM90 and LF130.  Pre-collars have been drilled to solid bedrock using an HWT (114.3mm) drill bit followed by diamond coring with a diameter of 63.5mm (HQ)  Diamond drilling of HQ3 (triple-tube) is undertaken to ensure maximum core recovery. Drill core has been orientated with a Reflex ACT III core orientation tool then continuously marked with a line while on an angle iron cradle. Sample Analysis Method Recent RC and Diamond Core sample preparation is undertaken by ALS, Adelaide, SA. Samples are dried at 90C for 6-12 hours, crushed with hammer mill to 70% passing 6mm, split using a riffle splitter and pulverised up to 3kg to 85% passing 75 microns. An 250g analytical split is sent to ALS Perth, WA for gold analysis. Analysis for gold is undertaken at ALS Perth, WA by 50g Fire Assay with an AAS finish to a lower detection limit of 0.01ppm gold using ALS technique Au-AA26. Fire Assay is considered a total digest method. ALS also conducted a 35 element Aqua Regia ICP-AES (method: ME-ICP41) analysis on each sample to assist interpretation of pathfinder elements. No field non-assay analysis instruments have been used in the analyses reported. A review of certified reference material and sample blanks inserted by the Company indicate no significant analytical bias or preparation errors in the reported analysis. Internal laboratory QAQC checks are reported by the laboratory and a review of the QAQC reports suggests the laboratory is performing within acceptable limits. Resource Modelling and Estimation Methodology The Comstock mineralised structures are interpreted to occur on the footwall and hanging-wall sides of a 20 – 50-metre-wide shear zone that is roughly the attitude of the open cut. They have a very steep > 700 dip and undulate back to -900 to the east. The development of ore shoots is important as they can A S X : AK A BRINGING VICTORIA'S GOLD TO LIFE 11 13 JUNE 2025 localise the higher-grade gold zone, however they can be difficult to model due to the short scale of the structures. A total of four mineralised gold domains have been interpreted based on drill hole logging and assay results. The domains are roughly reflecting the 0.5 g/t gold cutoff. Separate higher-grade sub-domains have been defined within the main Comstock Shear domain. These domains, have been combined during the geostatistical analysis and separated for grade estimation. Continuity of geology can generally be traced from section to section using geochemical and visual attributes. Area shear mineralisation extends for 1,200m along strike, from outcrop to the deepest drilling ~350m below surface. The database files, geological and mineralisation wireframes have been imported into Maptek Vulcan software v9.0 for use in the estimation. The resource database has been flagged with unique domain codes as defined by the geology and mineralisation wireframes and composited to 1m using the best fit algorithm in Vulcan. A block model has been constructed covering the extents of the deposit with a parent block size of 12m (X) by 12m (Y) by 12m (Z) utilised. A sub block size of 2m (X) by 2m (Y) by 2m (Z) has been used to define the mineralisation edges with the estimation undertaken at the parent block scale. The parent block size is considered appropriate for the drillhole spacing defining the mineralisation. Composite data within the resource database was assessed for the need of a top-cut to be applied to data prior to grade estimation. The determination of a high-grade cut is made on the basis of probability plots and ranked data values. A 30 g/t top-cut for gold was applied due to the outliers and the grade cutting only affected 3 composite intervals. These top-cuts are conservative, with a very low impact to the overall mean grade. Grade estimation of gold and silver has been completed using Inverse distance weighted to the power of two (ID2) into four gold- silver domains. Dynamic anisotropy has been used to orientate the search ellipse according to the dip and strike of the individual domains. Grade estimation was caried out in numerous passes on the individual lode/ vein and shear interpretation solids. For the MRE calculation (Passes 1-4) were used and for the Exploration Target generation Passes (5-6)were used. Blocks estimated in previous passes were not re-estimated in subsequent passes. Visual comparison of composite sample grade and block grade has been conducted in cross-section and in plan. Visually the block model reflects the input composite grades. Also utilised were a global comparison of the average composite and estimated block grades, and moving window averages comparing the mean block grades to the composites. Cut-Off Grades Statistical analysis of the length weighted gold grades at Comstock indicated a transition from unmineralised to mineralised at around 0.2 g/t gold. This threshold value was considered too coarse, and the grade shells were constructed at a higher 0.5 g/t gold cutoff and used as the basis for the interpretation and initial modelling of the mineralisation. Up to 5 m of internal waste have been included A S X : AK A BRINGING VICTORIA'S GOLD TO LIFE 12 13 JUNE 2025 to account for the un-mineralised to mineralised contacts and ensure continuity between intercepts along strike and down dip. Mining and Metallurgical Methods and Parameters, and other modifying factors considered to date No mining factors or assumptions have been made for the MRE. Resource tonnes are expressed as insitu. No Metallurgical or metal recovery studies have been completed. Mineralisation at Comstock is expected to be suitable for open cut mining and likely underground mining for deeper resources. The deposit is located in a well-established mining region and is in close proximity to exiting transport, energy and other support infrastructure. Criteria for Classification The classification considers the relative contributions of geological and data quality and confidence, as well as grade confidence and continuity. The resource classification has been applied to the Mineral Resource estimate based on the drilling data spacing, grade and geological continuity, and data integrity. No areas of the in situ Mineral Resource satisfied the requirement to be classified as Measured Mineral Resources. No areas of the in situ Mineral Resource satisfied the requirement to be classified as Indicated Mineral Resources. Inferred Mineral Resources are informed by drilling spaced from 60 m by 60 m. In general, the Inferred classification is inclusive of blocks estimated on the first, second and third passes. Inferred Mineral Resources have been informed by drilling spaced at 60m anisotropic distances, by search definition in the informed areas and above the 0 RL. Inferred criteria includes >= 2 samples and >=2 drillholes at a minimum. In general, the Inferred classification is inclusive of blocks estimated on the first, second and third second pass’s and forms a boundary between interpolation and extrapolation of the input data. Inf The classification reflects the view of the Competent Person for this type of mineralisation. St Arnaud Goldfield background The St Arnaud Gold field was mined from the mid-1850s to the early 1900s, producing approximately 400koz Au at an average grade of 15g/t1. The most significant production was from the Lord Nelson Shaft which reached a depth of 786m2. Gold is hosted within quartz reef systems that have developed in steeply west dipping thrust faults proximal to a fold hinge, similar to the Fosterville Gold Mine. The St Arnaud Project is located in the Stawell Structural Zone with the St Arnaud Fault in the east and Percydale Fault in the west, which are both prospective for orogenic gold mineralisation. Previous exploration programs by the Company have upgraded the priority of the Nelson and New Bendigo Lines. The St Arnaud Gold Project is considered highly prospective for the discovery of orogenic and intrusiverelated gold. EL006819 overlies the historic St Arnaud goldfield where extensions to known mineralisation present key targets. The quartz reef systems can extend for a few metres to a few kilometres along strike but are usually a few hundred metres strike length. 1 2 St Arnaud 1:100 000 Map Area Geological Report No 110, Department of Natural Resources and Environment Victorica, 1997.
