Announcement PDF ASX Announcement 22 September 2025 Arrakis Gold Discovery Confirmed With 54m*1 @ 1.2g/t Au from 108m • Results from 25IWBRC0040 and 25IWBRC0041 have been received, with results confirming the Arrakis gold discovery; significant intercepts include: o 54m*1 @ 1.2g/t Au from 108m to EOH in 25IWBRC0040, including  24m @ 2.1g/t Au from 138m to EOH. This interval further includes: • 8m @ 4.7g/t Au from 154m to EOH. o 6m @ 1.1g/t Au from 180m to EOH in 25IWBRC0041. • These intercepts are the first results from the recently completed 1,374m Arrakis RC drilling program. The RC program saw seven holes completed below air-core intercepts that define the 2.2km long mineralised Arrakis structure hosted within the Caladan target area. • Both 25IWBRC0040 and 25IWBRC0041 were drilled below the previously reported air-core intercepts from 25IWBAC044, including: o 11m @ 1.4 g/t Au*2 from 71m in 25IWBAC044, including  o 6m @ 2.3 g/t Au from 72m, and, 1m @ 1.0g/t Au from 87m to EOH in 25IWBAC044. • Results combined with geological observations confirm primary mineralisation within fresh rock with an apparent sub-vertical geometry. • Results from a further five RC holes broadly testing the Arrakis trend over 2.2km of strike are anticipated over the coming weeks. • Diamond drilling is being designed and scheduled to re-enter and extend 25IWBRC0041, along with RC drilling along strike to the north and south. *1: Down-hole width reported, as true width is uncertain, and further drilling is required to confirm the geometry of mineralisation. Potential true-width is discussed within the body of this report. *2: Previously released air-core drilling results see ASX releases dated 10 July 2025, 31 July 2025 & 18 August 2025.

These first results demonstrate significant primary fresh rock mineralisation, confirming the discovery of a new mineralised system at Arrakis and the capacity for this system to be large in scale. Well done to the Yandal team, whose resolve and focus on executing the long-term exploration strategy have been paramount to this success. The Arrakis trend has been defined over more than 2.2km based on 400m and 800m spaced air-core lines. The impact of this discovery will be determined with further results and as exploration is progressed; however, the discovery potential is substantial when you consider the scale of the trend, and the limited and broadly spaced nature of current drilling. Our priority going forward is simple: to confirm the extent of primary fresh rock mineralisation across the 2.2km of strike. With one heritage survey complete and a second scheduled for the end of September, Yandal will soon have a significant amount of drilling positions available from which to progress the Arrakis discovery.” Yandal Resources Ltd (ASX: YRL, “Yandal Resources” or the “Company”) is pleased to report that the first results from 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 the first two holes, 25IWBRC0040 and 25IWBRC0041, indicate: • Significant primary mineralisation within fresh rock, including a higher-grade mineralisation within a broader low-grade envelope, • Down-dip mineralisation continuity below recent air-core intercepts, • Broader mineralisation within fresh rock relative to air-core intercepts that occur within weathered or partially weathered rock, indicative of gold depletion within the weathering profile, • A sub-vertical mineralisation geometry. These results suggest the presence of a significant mineralised system and confirm Arrakis as a new gold discovery within Yandal Resources Ironstone Well-Barwidgee Gold Project. 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 3), 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 Arrakis Cross-Section A northwest facing Transported Cover Surface 1m @ 1.0 g/t Au to EOH 11m @ 1.4 g/t Au incl. 6m @ 2.3 g/t Au Regolith Anomalies Dolerite 54m @ 1.2 g/t Au incl. 24m @ 2.1 g/t Au to EOH 6m @ 1.1 g/t Au to EOH Dolerite Figure 1: Cross-section showing all RC drilling results from 25IWBRC0040, with a simple preliminary interpretation of geology.

The section shows all drilling within +/- 50m of the section plane. yandalresources.com.au | ASX:YRL 3 Arrakis RC Drilling Results RC holes 25IWBRC0040 and 25IWBRC0041 were drilled on the same line as air-core hole 25IWBAC044 (see ASX release 31 July 2025) that returned an air-core intercept of 11m @ 1.4 g/t Au from 71m, and 1m @ 1.0g/t Au at end-of-hole (EOH) (see Figures 1 and 2). Collar and intercept details are listed in Tables 2 and 3. 25IWBRC0040 has confirmed significant fresh rock gold mineralisation (see Figure 1 and Appendix 1) with an intercept of: o 54m @ 1.2g/t Au from 108m to EOH, and includes a higher-grade interval  24m @ 2.1g/t Au from 138m to EOH, this interval further includes  8m @ 4.7g/t Au from 154m to EOH. (Intercepts calculated using a >0.3g/t cut off and no more than 4m of continuous internal waste) 25IWBRC0041 intercepted several broad intervals of gold anomalism (gold values 0.1-0.3g/t Au) before a heavily weathered shear zone from 126-150m. The RC hole then intercepted the edge of the targeted mineralised structure at the end-of-hole with: o 6m @ 1.1g/t Au from 180m to EOH. Using these two intercepts and geological observations from RC chip logging, mineralisation is interpreted to be sub-vertical with an apparent width of approximately 30m (please note, this assumes mineralisation is striking to the north-west, at an orthogonal, 90° angle, to the drill section. Further drilling is needed to confirm the true width of mineralisation). These first RC drilling results demonstrate the capacity for the Arrakis Prospect to host a largescale mineralised system, with recently completed broad spaced air-core drilling identifying mineralisation across five consecutive and broadly spaced lines, covering more than 2.2km of strike. The Company’s aim going forward will be to confirm the extent of primary fresh rock mineralisation across the 2.2km of strike. 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 late September or 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 holes drilled below recent air-core intercepts, the Yandal exploration team will begin the design and scheduling of follow-up drilling. Immediate priorities will include re-entering and extending 25IWBRC0041 with diamond drilling and the completion of RC drilling across 200m spaced lines to the northwest and southeast of 25IWBRC0040, and across the currently defined Arrakis trend. Geological Observations Mineralisation within 25IWBRC0040 is hosted within a variably foliated (secondary shearing) and heavily altered sequence. High-grade mineralisation intercepted at the end of 25IWBRC0040 is associated with several narrow intervals of micro-crystalline quartz alteration/veining (or a primary chert) with fine disseminated sulphides, within a heavily sheared and fractured, possibly mafic-derived unit that includes fine irregular quartz veining. This interval displays intense (see Figure 3) silica-albite-carbonate alteration (+/- biotite, chlorite and sericite) with disseminated fine to medium-grained pyrite and arsenopyrite up to 5% within some chips, or as stringers parallel to fine veins or the dominant foliation. Broader, lower-grade mineralisation is associated with pervasive sericite alteration (primary lithology assumed to be mafic in origin; however, further analysis is needed to confirm) with trace to 1% fine disseminated pyrite and arsenopyrite. This interval includes minor veining and quartzfilled fractures. Narrow quartz-phyric and heavily silica-altered intrusive intervals have also been observed amongst lower-grade mineralisation. yandalresources.com.au | ASX:YRL 5 5m @ 0.7g/t Au from 112m to EOH 11m @ 2.1g/t Au from 90m Incl. 7m @ 3.1g/t Au 11m @ 1.7g/t from 97m to EOH 12m @ 1.1 g/t Au from 45m & 12m @ 0.5 g/t Au from 70m to EOH Air-core Regolith Anomaly 25IWBRC0041 6m @ 1.1 g/t Au to EOH Interpreted Arrakis Structure 11m @ 1.4 g/t Au from 71m & 1m @ 1.0 g/t Au to EOH 25IWBRC0040 54m @ 1.2 g/t Au incl. 24m @ 2.1 g/t Au to EOH 9m @ 1.2 g/t Au Incl. 1m @ 7.7 g/t Au 22m @ 0.4 g/t Au from 75m 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 22 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.

ASX Announcement 22 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. Sample sizes are appropriate given the fine-to-medium-grained nature of the sampled material. 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.
