The initial 400m and 800m line spacing used for air-core drilling was applied to define a target. We are now seeing evidence of a potentially continuous mineralised system over this same spacing. As we step out and consider the whole 2.2km trend initially defined by air-core drilling, the scale of this discovery begins to look regionally significant.” Yandal Resources Ltd (ASX: YRL, “Yandal Resources” or the “Company”) is pleased to report that the results from 25IWBRC0042 and 25IWBRC0043, part of the recently completed reverse circulation (RC) drilling program across the Arrakis Prospect, have been received. The RC drilling program included seven (7) RC holes for a total of 1,374m, across 400m and 800m spaced lines targeting mineralisation intercepted within recent air-core drilling that defines the more than 2.2km long mineralised Arrakis structure. The RC program was designed to confirm mineralisation continuity and geometry within fresh rock below several significant air-core intercepts that occurred in either fully or partially weathered rock. Results from holes, 25IWBRC0042 and 25IWBRC0043, indicate: • Primary mineralisation within fresh rock, including a higher-grade mineralisation within a broader low-grade envelope over a 400m spacing, providing the first evidence of potential fresh rock mineralisation continuity along strike, • A similar mineralisation style to previously reported intercepts from drilling 400m to the southeast, further supporting the early evidence of fresh rock mineralisation continuity along strike, • Re-confirms a sub-vertical mineralisation geometry, and • Demonstrates the potential for continuous primary mineralisation across the more than 2.2km trend that defines the Arrakis Prospect. These results further enhance the Company’s confidence that Arrakis hosts a significant mineralised system. The Arrakis Prospect is located within the Caladan target area (tenements E 53/1843, E 53/2304, E 53/2192 and E 53/1882), part of the broader Ironstone Well-Barwidgee Gold Project (see Figure 4), located 60km south of the Jundee mining complex (ASX: NST), and 18km north the recent Siona discovery, within the Yandal Greenstone Belt. yandalresources.com.au | ASX:YRL 2 Plan View Arrakis Cross-Section A northwest facing Surface Transported Cover 12m @ 1.1 g/t Au 6m @ 0.3 g/t Au Basalt 12m @ 0.5 g/t Au 6m @ 0.8 g/t Au 50m @ 1.3 g/t Au incl. 28m @ 1.9 g/t Au Regolith Anomalies 16m @ 0.7g/t Au Dolerite Figure 1: Cross-section showing all RC drilling results from 25IWBRC0042 and 25IWBRC0043, with a simple preliminary interpretation of geology.

Please note the plan view at top of section and the 30m offset between intercepts within the two reported RC holes. yandalresources.com.au | ASX:YRL 3 Arrakis RC Drilling Results RC holes 25IWBRC0042 and 25IWBRC0043 were drilled on the same line as air-core hole 25IWBAC032 (see ASX release 10 July 2025) that returned an air-core intercept of 12m @ 1.1 g/t Au from 45m, and 12m @ 0.5g/t Au from 70m Au to end-of-hole (EOH) (see Figures 1 and 2). Collar and intercept details are listed in Tables 2 and 3. Both holes are located approximately 400m northwest of the recently reported intercepts from 25IWBRC0040 that included 54m @ 1.2g/t, including 24m @ 2.1g/t Au. 25IWBRC0042 has intercepted significant fresh rock gold mineralisation (see Figure 1 and Appendix 1) with an intercept of: o 50m @ 1.3g/t Au from 122m in 25IWBRC0042 (ETW of 24m), including  28m @ 1.9g/t Au from 143m, (Intercepts calculated using a >0.3g/t cut off and no more than 4m of continuous internal waste) 25IWBRC0043 is offset from 25IWBRC0042 by 30m to the southeast (see Figure 1) and intercepted: o 16m @ 0.7g/t Au from 140m in 25IWBRC0043 (ETW of 12m), including  9m @ 1.0g/t Au from 140m. The estimated true widths (ETW) have been calculated and reported above. These true widths are calculated based on the assumption that mineralisation is sub-vertical and striking to the northwest (approx. 320°). Mineralisation, alteration and deformation styles within both holes are comparable to those observed in fresh rock intercepts from 25IWBRC0040 and 25IWBRC0041 (see Figure 3 for visual examples of alteration associated with gold mineralisation from 25IWBRC0042). Alteration observed includes variable intensities of silica-carbonate +/- sericite, chlorite, albite and biotite alteration. Quartz veining up to 5% occurs through the intervals, along with fine disseminated pyrite +/- arsenopyrite, with intermittent coarse blebs and stringers. The similarity of deformation textures and alteration between the fresh rock intercepts to date is encouraging. It suggests mineralisation is part of the same mineralised system, providing the first indication of mineralisation continuity along strike, despite the 400m line spacing between results. Both 25IWBRC0042 and 25IWBRC0043 also intercepted several zones of low-grade mineralisation and anomalism within the weathering profile. These zones represent targets where they project into fresh rock beneath and will be tested during the next phase of diamond and RC drilling. yandalresources.com.au | ASX:YRL 4 Next Steps A heritage survey clearing 200m spaced lines across the Arrakis Prospect was completed earlier in September. A second survey is scheduled for early October to clear 100m spaced lines across the Prospect. These two surveys will provide ample capacity for further drilling across the Arrakis Prospect. While the Company awaits further results from the remaining three RC holes (25IWBRC0044, 25IWBRC0045, and 25IWBRC0046; see Figure 2), preparations are underway for an approximately 1,200m diamond drilling program that will see diamond tails completed down several RC holes. In addition to this, diamond holes will be drilled to test below recent RC intercepts and to test the fresh rock position below parallel regolith anomalies. Diamond drilling is scheduled to commence in October. Follow-up RC drilling is also planned; this drilling will look to complete 200m spaced lines across the 2.2km striking Arrakis trend and complete additional RC holes across existing lines. This program may be up to 6,000m, subject to further results and geological observations. yandalresources.com.au | ASX:YRL 5 5m @ 0.7g/t Au from 112m to EOH 11m @ 1.7g/t from to EOH 25IWBRC0045 Assays Pending 25IWBRC0044 Assays Pending 12m @ 1.1 g/t Au & 12m @ 0.5 g/t Au to EOH 25IWBRC0043 16m @ 1.1 g/t Au 25IWBRC0041 6m @ 1.1 g/t Au to EOH 11m @ 2.1g/t Au Interpreted Arrakis Structure 25IWBRC0042 50m @ 1.3 g/t Au incl. 38m @ 1.9g/t Au 25IWBRC0046 Assays Pending 25IWBRC0040 54m @ 1.2 g/t Au incl. 24m @ 2.1 g/t Au to EOH 22m @ 0.4 g/t Au Incl. 7m @ 1.2 g/t Au Figure 2: A collar plan over the Arrakis Prospect within the Caladan target area, showing simplified bedrock geology interpretation.

The following Table and Sections are provided to ensure compliance with the JORC Code (2012 edition) requirements for the reporting of Exploration Results. Section 1 Sampling Techniques and Data 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 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. • 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 ASX Announcement 24 September 2025 • • Yandal Resources has completed RC drilling across several 400m and 800m spaced lines across the Arrakis Prospect, targeting fresh rock mineralisation below recently reported air-core intercepts. The drilling involved 139mm face sampling bit down to between 162m and 288m. Holes were drilled at an angle of -60° to the southwest. Yandal Resources (YRL) RC drilling samples were collected via a rig-mounted static cone splitter, splitting approximately 12.5% of the total sample volume. Two splits are collected for each metre: a primary and duplicate sample. The primary 1m samples are then sent to a lab for further analysis. The duplicate samples are retained on-site unless they are submitted as routine duplicates. For YRL RC drilling, the cone splitter is regularly cleaned and inspected. The 1m bulk samples are laid out in drill order. These bulk samples are regularly inspected for contamination, and the volume of the bulk sample is monitored. These bulk samples are retained until all results are received and may be used to collect additional field duplicates to verify lab results, logged geology or any other form of analysis. If the bulk sample appears visually low in volume or weight, this is recorded with the sample details. The same applies to damp or wet samples. Two splits are collected for each drilled metre: a primary and a secondary sample. The Secondary sample is retained on-site and may be used to collect additional field duplicates to verify lab results, logged geology or any other form of analysis RC drilling was used to obtain 1m samples from which a portion, between 1-5kg in weight, was dispatched to Aurum Laboratories Pty Ltd: At the lab, samples were crushed and pulverised to produce a 50g charge for fire assay with an AAS (atomic absorption spectroscopy) finish for gold determination with a 0.01ppm detection limit. Page 13 Criteria JORC Code explanation Commentary commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. 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). • For YRL RC drilling, a 139mm diameter face sampling bit and hammer was used. Drill sample recovery Method of recording and assessing core and chip sample recoveries and results assessed. • For YRL holes, RC drilling recoveries are visually assessed by the supervising geologist, and any low-volume or weight samples are recorded, along with any damp or wet samples. Drill depths are routinely verified at the completion of each drill rod (every 6m). The cone splitter is checked for each drill site to ensure it is completely upright and level. Sample collection from the splitter by drilling off-siders is monitored for any inefficiencies. Within the limited drilling completed, there appears to be no correlation between sample recovery and sample grade. 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. 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. Sub-sampling techniques and sample preparation If core, whether cut or sawn and whether quarter, half or all core taken. ASX Announcement 24 September 2025 • • For YRL drilling, all RC holes have been logged in full by a qualified and experienced geologist. RC chips and fines from each 1m interval drilled are inspected and logged for colour, weathering, lithology, deformation, veining and sulphide species. All 1m samples are sieved and retained in labelled and annotated chip trays. Chip trays are transported to Perth for longterm storage and are available for review. The quality of logging information is considered sufficient to support Mineral Resource Estimation studies. Data captured through geological logging by a geologist is qualitative in nature. In addition to geological logging, the magnetic susceptibility of each interval is measured using a KT-10 magnetic susceptibility metre, with a sensitivity of 1x10-6 SI Units. Magnetic susceptibility readings are quantitative in nature. YRL RC drilling utilised a rig-mounted cone splitter installed directly below and in line with the rig-mounted cyclone. Two 1-3kg sub-samples are collected into calico bags labelled with a unique alpha-numeric ID. A majority of the samples collected were dry; if samples were damp or wet, this was noted in the sample records. For all YRL RC drilling, samples are dried at 100°C to constant mass, crushed to <10mm and Page 14 Criteria JORC Code explanation If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.

Field duplicates were collected at an initial rate of 1 duplicate for every 50 samples collected. Standards and blanks (certified reference material or CRM) were routinely inserted into the sample sequence at a rate of 1 CRM for every 20 samples collected. For labs used by YRL, internal lab quality control measures include lab duplicates and the insertion of lab standards and blanks.

ASX Announcement 24 September 2025 • • For YRL RC drilling, samples were assayed at the following labs using the following methods: o Aurum Laboratories in Beckenham, Western Australia, assayed using a 50g fire assay with AAS (atomic absorption spectroscopy) finish for gold analysis with a 0.01ppm detection limit. Magnetic susceptibility measurements were taken every meter using a KT-10 V2 instrument with a sensitivity of 1x10-6 SI Units. YRL QAQC field protocols include the insertion of commercially prepared certified reference material (CRM) and blank material at a rate of approximately 1 CRM/blank for every 20 samples collected. CRMs used are unidentifiable by the lab when received. QAQC performance is monitored upon receipt of each batch of results and re-assessed once all samples for a program are received. Laboratory QA/QC protocols involve inserting internal lab standards using CRMs, blanks, repeat analysis of pulps and screen tests (the percentage of pulverised material passing 75µm mesh). Laboratory QAQC results are reported with each batch. Laboratory QAQC performance is monitored upon receipt of each batch of results and assessed again once all samples for a program are received. Significant intercepts from YRL RC drilling are verified by YRL geologists through the visual inspection of chips, reviewing the spatial location of mineralisation relative to previous intercepts, and in the case of high-grade gold intercepts, the panning of drill fines to visually confirm gold in samples. No twinned holes have been completed across the Caladan or Irulan target area.
