25 FEBRUARY 2026 NEWLY IDENTIFIED HIGH GRADE SILVER COMPONENT TO ST ARNAUD COMSTOCK ST ARNAUD – COMSTOCK PROJECT UPDATE • Aureka Limited (ASX: AKA, Aureka or the Company) is pleased to announce high-grade gold assays and newly identified along strike significant silver mineralisation at the St Arnaud Comstock project, located in Central Western Victoria. The St Arnaud Comstock Project is a previous mine site with last production in 1995 that lies within the greater St Arnaud gold fields that historically produced 400koz at an estimated 15g/t Au1 . • Diamond hole 25NED004 intercepted significant zones of both gold and silver mineralisation, including the highest-grade silver hit on the project to date: ▪ 0.3m @ 650g/t silver and 1.91g/t gold from 192m, • Visible gold mineralisation intercepted within hole 25NED007 was reported in late December 20252 with the associated assays returning: ▪ 0.3m @ 31.5g/t Au from 127.5m. • These results demonstrate Comstock has the potential to deliver economic high-grade gold and silver from new structures proximal to, and potentially accessible from, the existing Comstock pit. The visible gold within hole 25NED007 was intersected near surface at approximately 140m west of the Comstock Fault, characterising a new mineralised structure sub parallel to the 56.5Koz inferred JORC Resource3 and approximately. 125m vertically from surface. • These results build on the previously reported 2025 diamond drilling program at Comstock undertaken by Aureka, which included: ○ 25NED0024 with standout results north of the pit: 1m @ 65.37g/t gold (Au) from 116.2m ▪ including 0.3m @ 109g/t and 0.4m @ 65.4g/t, ○ 25NED0015 with standout intercept 6.9m @ 4.24g/t Au from 422m, ▪ incl. 0.75m @ 18.6 g/t Au from 422.1m and 0.6m @ 19.9g/t Au from 435.9m0.75m @ 18.6 g/t Au from 422.1m and 3.2m @ 4.71g/t Au from 434.0m ▪ (incl. 0.6m @ 19.9g/t Au from 435.9m) 1 St Arnaud historical production taken from: Krokowski de Vickerod, J., Moore, D.H. and Cayley, R.A., 1997 2 ASX Release, 22 Dec 2025: St Arnaud Comstock – Shallow Visible Gold in New Structure 3 ASX Release, 13 June 2025: St Arnaud Maiden JORC MRE and Exploration Target - Amended 4 ASX release, 20 Nov 2025: St Arnaud Comstock – High grade assays 5 ASX release, 24 Jul 2025: Multiple high-grade gold intercepts at St Arnaud Comstock. 25 FEBRUARY 2026 Figure 1: Microscope image of quartz hosted Galena-Sphalerite-Chalcopyrite-Pyrite aggregates hosting Au and Ag mineralisation (0.3m @ 1.91g/t Au and 650g/t Ag from 192m) reported for the first time in this release hole 25NED004. 6 ASX Release, 13 June 2025: St Arnaud Maiden JORC MRE and Exploration Target - Amended Management Comment “It is great to see the St Arnaud Comstock growing on multiple fronts, to the north as reported in November, to the west as reported in December and now growing in metal diversity with high grade silver intercepts. This growth is taking shape at a time when the Company is actively progressing commercialisation options for Comstock.“ - James Gurry, Managing Director Exploration Manager Comment “Again, the most recent gold intercepts are beyond the current maiden 56Koz Au inferred JORC Resource6 and continue to reinforce the prospectivity of the Comstock project. With continued high graded gold intercepts and now demonstrated high grade silver grades, Comstock has the potential to provide increased economic optionality as the team explores and develops functional pathways to near-term small- scale production.” - Jozef Story, Exploration Manager 25 FEBRUARY 2026 Cautionary Statement The potential quantity and grade of the Exploration Target set out in Table 1 and Table 2 of this release are conceptual in nature and was reported in 2021 (Irvine) and 2025 (St Arnaud). There has been insufficient exploration to estimate a mineral Resource, and it is uncertain if further exploration will result in the estimation of a Mineral Resource. The Exploration Target has been prepared and reported in accordance with the 2012 edition of JORC Code. St Arnaud – Comstock - newly identified high grade silver • Aureka Limited (ASX: AKA, Aureka or the Company) is pleased to announce high-grade gold and along strike significant silver mineralisation the St Arnaud Comstock project, located in Central Western Victoria. Results reported within this announcement pertain to assays from 25NED007 and 25NED004, drilled in 2025 as a part of the total 2,253m diamond drilling program, recently received. • Significant zones of mineralisation intersected within 25NED004 are associated with a wide planar quartz vein with abundant large aggregates of galena sphalerite chalcopyrite and pyrite, including: ▪ 0.3m @ 650g/t silver and 1.91g/t gold from 192m, ▪ And 0.42m @ 8.5g/t Au and 22g/t Ag from 186.4m. • The high-grade silver and moderate gold intercept within 25NED004 occurs within subparallel bedding planar quartz vein within a massive sandstone, footwall to a newly interpreted Comstock Basal fault. This structure has not been tested by any previous drilling and can be projected to surface north of the Comstock Pit. • This mineralisation is consistent with previously reported high grade gold and silver intercepts in Comstock, for example in NED0097 : o 1m @ 2.96 g/t Au, 59.2 g/t Ag from 194.65 m, and o 0.55 m @ 10.9 g/t Au, 52.8 g/t Ag from 195.65 m. • Mineralisation intercepted in hole 25NED007 is associated with previously reported visible gold intersected near surface approx. 140m west of the Comstock Fault8 , characterising a new mineralised structure sub parallel to the 54Koz inferred JORC Resource9 and approx. 125m vertically from surface. ▪ 0.3m @ 31.5g/t Au from 127.5m. • Both intercepts are within the defined Exploration Target area and outside of the maiden 56Koz resource, reported in June 20259 and continue to support the ongoing exploration upside and potential to significantly grow the current resource and deliver a pipeline to near-term small-scale production (refer Tables 1 & 2, page 13). • Aureka’s St Arnaud Comstock pit is a previous mine site (last production 1995) and lies within the greater St Arnaud area that historically produced 400koz of gold at an estimated 15g/t10 plus associated silver production. 7 ASX Release, 21 Jan 2022: Maiden Diamond Drilling on St Arnaud’s Nelson Line Intersects Broad Gold and Silver Mineralisation 8 ASX Release, 22 Dec 2025: St Arnaud Comstock – Shallow Visible Gold in New Structure 9 ASX Release, 13 June 2025: St Arnaud Maiden JORC MRE and Exploration Target - Amended 10 St Arnaud historical production taken from: Krokowski de Vickerod, J., Moore, D.H. and Cayley, R.A., 1997. 25 FEBRUARY 2026 Figure 2 – Comstock Long section with significant mineral intercept.

Bedding parallel visible-gold bearing quartz lodes are typical of the St Arnaud goldfields. This result demonstrates the potential for additional mineralised zones to be delineated in close proximity to the existing St Arnaud Comstock resource. The high-grade silver and moderate gold intercept within 25NED004 of 0.3m @ 1.91g/t gold and 650g/t silver from 192m occurs within subparallel bedding planar quartz vein within a massive sandstone, footwall to a newly interpreted Comstock Basal fault. This structure has not been tested by any previous drilling and can be projected to surface north of the Comstock Pit. Geological Model updates: Cross sectional and 3D interpretation of Aureka’s 2025 drilling campaign have demonstrated along strike and down dip continuity of the steeply west-dipping Comstock Shear to the north of the Comstock pit. The deeper drilling has identified a second order west-dipping mineralised fault, referred to here as Comstock Basal Fault, which shows marked changes in alteration, veining intensity and bedding orientation from hanging wall to footwall. Previously reported significant intercepts in 25NED00111 of 0.75m @ 18.6 g/t Au from 422.1m and 0.6m @ 19.9g/t Au from 435.9m sit just footwall to the southerly projection of Comstock Basal Fault, suggesting this structure has the potential to host further high-grade mineralisation with depth continuity. Geological interpretation is ongoing, integrating recent observations with legacy drilling and observations to identify further drill targets below and beyond the Comstock Pit.

Comstock is located within the historic St Arnaud Goldfields along the Nelson line of reef and is situated approximately 2 kilometres north of the township of St Arnaud. Locally, the geology of the Comstock project 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 plunging 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 St Arnaud Comstock pit is a previous mine site (last production 1995) and lies within the greater St Arnaud gold fields that historically produced 400koz at an estimated 15g/t Au15 . There appears to be an apparent association with green-black carbonaceous shales and higher gold grades. Commercialisation strategy St Arnaud Gold Project and the Comstock pit lie within trucking distance to a number of gold processing plants in Victoria. With the current strong gold price environment Aureka intends to begin community, scoping and regulatory approval work to plan for a productive future at Comstock and the St Arnaud gold field. On 8 December 2025, Aureka announced it has engaged mill owners and small-scale Victorian gold production specialists, Core prospecting, to assist with the advancement of the St Arnaud Comstock Project and significantly de-risk Aureka's potential pathway to first production16 . 15 St Arnaud historical production taken from: Krokowski de Vickerod, J., Moore, D.H. and Cayley, R.A., 1997 16 ASX Release, 08 December 2025: Core Prospecting St Arnaud Engagement 25 FEBRUARY 2026 Figure 7 – St Arnaud Comstock pit, looking SE, situated within EL006819. 25 FEBRUARY 2026 Figure 8 – St Arnaud Comstock Project relative location to a number of gold processing mills in Victoria including Wedderburn within the 50km range. 25 FEBRUARY 2026 Cautionary Statement The potential quantity and grade of the Exploration Target set out in Table 1 and Table 2 of this release are conceptual in nature and was reported in 2021 (Irvine) and 2025 (St Arnaud).

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 (eg submarine nodules) may warrant disclosure of detailed information. Air Core & Reverse Circulation Drilling • All air-core (AC) drill holes have been routinely sampled at 1m intervals downhole directly from a rig mounted cyclone. Each metre is collected and placed on a plastic sheet on the ground and preserved for assay sub-sampling analysis as required. For RC, each metre of sampling is collected in individual sequentially numbered plastic bags and preserved. • Sub-samples for assaying are generated from the 1m preserved samples and have been prepared at the drill site by either a spear sampling method (AC) or riffle split (RC) based on logged geology and mineralisation intervals. Sub- samples have been taken at 1m intervals or as composites ranging from 2-5m intervals ensuring a sample weight of between 2 to 3 kg per sub- sample. • Certified reference material and sample duplicates have been inserted at regular intervals with laboratory sample submissions. Diamond Core Drilling • The diamond drill core samples are selected on geological intervals varying from 0.2m to 1.3m in length. • All drill core is routinely cut in half (usually on the right of the marked orientation line) with a diamond saw and submitted for analysis. Representative sampling is ensured by a combination of Company procedures regarding quality control (QC) and quality assurance/ Testing (QA). Certified standards and blanks are routinely inserted into assay batches. Drilling techniques • Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details Air Core (AC) Drilling • Legacy AC drilling has been carried out using a Wallis Mantis 80 AC rig mounted 25 FEBRUARY 2026 (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). 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 • Legacy 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 • Legacy diamond drilling was 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. • Drilling completed by Aureka was conducted by AMWD • Pre-collars were drilled to solid bedrock using an HQ3 drill bit (93mm hole diameter) coring down to solid rock followed by HWT casing diamond (114.3mm hole diameter) • Diamond drilling of HQ3 (triple-tube) was 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 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. Air Core & Reverse Circulation Drilling • Legacy AC & RC drill recoveries have been visually estimated as a semi-quantitative range and recorded in the log. • Recoveries are generally high (>90%), with reduced recovery in the initial near-surface sample. • Samples are generally dry, but many became wet at the point of refusal in hard ground below the water table. • Geological control maintained at the drill site at all times to ensure drilling and sampling is to required standard. 25 FEBRUARY 2026 • No sampling issue, recovery issue or bias has been picked up and is considered that both sample recovery and quality is adequate for the drilling technique employed. Diamond Core Drilling • All diamond core has been logged capturing any core loss, if present, and recorded in the database. • All drill depths are checked against the depth provided on the core blocks and rod counts are routinely carried out by the driller. Core recovery for the areas sampled is generally good. 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. • Geological logging of samples follows Company and industry common practice. Qualitative logging of samples includes (but is not limited to), lithology, mineralogy, alteration, veining and weathering. • All logging is quantitative, based on visual field estimates. • Most if all AC & RC chips and core were photographed in detail. • For AC & RC, a small representative sample has been retained in a plastic chip tray for future reference and logging checks. • Detailed chip logging, with digital capture, has been conducted for 100% of chips logged by previous geological teams. • Detailed core logging, with digital capture and digital photography, was conducted for 100% of the recent Aureka diamond drilling 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. Air Core & Reverse Circulation Drilling • Procedures have been followed to ensure sub-sampling adequacy and consistency. These included (but are not limited to), daily workplace inspections of sampling equipment and practices. • Only recent core drilling incorporated blanks and certified reference materials are submitted with the samples to the laboratory as part of the quality control procedures. • AC composite, 1m individual and EOH samples have been collected as grab samples. • Legacy drill sample preparation and base metal and precious metal analysis is undertaken by a registered laboratory (ALS Perth, WA). Sample preparation by dry pulverisation to 85% passing 75 microns is undertaken by ALS Adelaide, SA. • The sample sizes are considered appropriate to correctly give an accurate indication of mineralisation given the qualitative nature of the technique and the style of gold mineralisation sought. 25 FEBRUARY 2026 Diamond Core Drilling • Detailed diamond core logging, with digital capture, has been conducted for 100% of the core by previous geological team. • Half core is sampled from NQ and HQ diameter drill core. • Company procedures have been followed to ensure sub-sampling adequacy and consistency. These included (but are not limited to), daily workplace inspections of sampling equipment and practices. • Blanks and certified reference materials are submitted with the samples to the laboratory as part of the quality control procedures. • No second-half sampling has been conducted at this stage. • The sample sizes are appropriate to correctly represent the sought-after mineralisation. 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. • Sample preparation for legacy samples was 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 was 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 materia
