For further information or to ask questions concerning this announcement, please visit our Investor Hub at https://investorhub.yandalresources.com.au/link/qy1plP Yandal Resources Ltd (ASX: YRL, “Yandal Resources” or the “Company”) is pleased to advise that the first phase of air-core (AC) drilling across Caladan and Irulan (E 53/1843, E 53/2304) target areas within the Ironstone Well-Barwidgee (IWB) Gold Project has commenced. The Caladan and Irulan target areas represent early-stage, large-scale exploration targets identified following the completion of a ground gravity survey in early 2024 (see ASX releases dated 11 June 2024 and 15 July 2024). Air-core (AC) drilling will include one line across the core of the Caladan target area, testing the core of the Cal-01 anomaly (see Figure 2) and 800m spaced lines across the northern half of the Irulan target area that will test the IRU-01 Anomaly (See Figure 2).

The only systematic drilling across the fold structure was completed in 1995 (see ASX 15 July 2024), where shallow vertical RAB holes on a 400m by 400m spacing were completed. The drilling was designed to penetrate through shallow transported cover and sample in-situ upper saprolite clays. A review of this drilling yielded several low-level saprolite anomalies, the largest of which is situated in the core of the Caladan Fold (see Figure 2 below). The Caladan Fold structure is 3km wide, over 8km long, and lies under 2m to 20m of loose to partially cemented transported cover (the average depth of transported cover is 8m). The broad structural setting is similar to the Kalgoorlie district, where the Boulder-Lefroy Fault truncates the folded mafic stratigraphy of the Boomerang anticline. The under-explored nature of the Caladan Fold, combined with several low-level regolith anomalies, presents the Caladan target area as a high-priority early-stage exploration target area within the Company’s project portfolio. Irulan The Irulan target area presents a large mafic dolerite complex up to 1km wide and interpreted over more than 8km of strike. The regional Barwidgee Shear Zone brackets the dolerite complex to the southwest and the Idaho Shear to the northeast. It is also bound by interpreted volcanosedimentary units along both margins (see Figures 1 & 2). Previous drilling completed at the Rosewall Prospect within the Irulan target area (see ASX release dated 15 July 2024) demonstrates the potential for the dolerite complex to host highgrade mineralisation with intercepts, including: o 9m @ 4.6g/t Au from 12m in GCMBDYC43 (historic drilling)  o 10m @ 2.4 g/t Au from the surface in YRLAC0033  o Including 4m @ 3.9g/t Au from 16m 7m @ 2.0g/t Au from 16m in YRLAC0031  o Including 5m @ 4.1g/t Au from the surface 7m @ 2.7g/t Au from 14m in YRLRC00469  o Including 5m @ 7.6g/t Au from 13m Including 3m @ 4.0g/t Au from 20m 6m @ 2.0g/t Au from 13m in YRLRC0469 yandalresources.com.au | ASX:YRL 2 The ground gravity survey completed in early 2024 refined and highlighted the Company’s interpretation of the mafic package, highlighting the extent of the dolerite complex and numerous cross-cutting structures. Dolerite is a regionally significant host for orogenic gold mineralisation within the Yandal greenstone belt, with most high-grade lodes at the world-class Jundee deposit hosted within the Barton dolerite. The Irulan dolerite complex presents an analogous litho-structural setting to the Jundee deposit, with a large dolerite complex that is bracketed by late volcano-sedimentary units and directly adjacent to the regional Ockerburry hear zone. yandalresources.com.au | ASX:YRL 3 Figure 1: A simplified bedrock geology interpretation across the IWB Gold Project with the main features of the preliminary ground gravity interpretation, including conceptual target areas.

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 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. ASX Announcement 10 October 2024 • All drilling and exploration data discussed in this release has been previously reported; see: o Large-scale Gold Anomalies Across Emerging Targets, 15 July 2024 o Exploration Update – Yandal Gold Projects, 4 July 2019 o Encouraging Drill Results – Yandal Gold Projects, 21 March 2019 o Replacement Prospectus, 12 December 2018 For 2019 YRL AC drilling, 4m composite samples were taken with a 50mm diameter PVC spear thrust to the bottom of the AC sample pile, laid out as individual metres piles in order on the ground. If the 4m composites were anomalous, a 1m single split is collected using the spear. The average sample weight is about 4.0kg for 4m composites and 2.0-2.5kg for 1m samples. For 2019 and 2020 YRL RC Drilling, 4m composite samples were taken with a 50mm diameter PVC spear thrust to the bottom of the RC sample pile, laid out as individual metres piles in order on the ground. If the 4m composites were anomalous, the 1m sample derived from the onboard cone splitter and stored in a calico bag with a unique ID is collected. For historic RAB drilling completed by Eagle Mining in 1995, derived from WAMEX Report A047408, samples were taken over discrete lithological changes of varying lengths. Holes were terminated once a recognisable saprolitic horizon was intercepted. For historic RAB drilling completed by Hunter Resources in 1995, derived from WAMEX Report A047408, samples were collected as 4m composites from the transported/residual interface to the bottom of the hole. For historic RAB drilling, it is assumed that sample methodologies were industry standards and likely involved collecting sample material from 1m sample piles laid out in order on the ground adjacent to the collar. For YRL AC and RC drilling, recovery and drill depth were assessed by comparing drill chip volumes (sample bags) for individual meters. Estimates of sample recoveries were routinely recorded. Routine checks for correct sample depths are undertaken after the completion of every rod (3m for AC and 6m for RC). Page 10 Criteria JORC Code explanation Commentary • • 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. • • • 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). Drill sample recovery Method of recording and assessing core and chip sample recoveries and results assessed. • • • • • ASX Announcement 10 October 2024 For YRL drilling, AC and RC sample recoveries were visually checked for recovery, moisture and contamination. The cyclone was routinely cleaned to ensure no material buildup. Due to the generally good drilling conditions around the Rosewall Prospect (no groundwater and shallow weathering profile), samples are considered to be of high quality and representative of the intervals drilled. For YRL AC and RC 2019-2020 samples, drilling was used to obtain 1m samples, from which approximately 2.0-2.5kg was pulverised to produce a 50g charge for fire assay when 4m composite assays were anomalous. AC and RC chips were geologically logged over 1m intervals and initially sampled over 4m intervals to create a composite sample (assayed via Aqua Regia partial digest with AAS determination). Anomalous 4m intervals were then sampled over 1m intervals via the fire assay method. Depending on the hole depth, the maximum composite interval was 4m, and the minimum was 2m. Samples were analysed for only the programs. Drilling intersected transitional mineralisation to a maximum drill depth of 23m. For historic RAB drilling completed by Eagle Mining in 1995, derived from WAMEX Report A047408, 2m to 5m composite samples and 1m samples were taken based on discrete lithological units (loose transported cover, consolidated transported cover, saprolite clays, etc.). Samples were then pulverised and analysed for gold by BETA aqua regia method with a carbon rod finish with ASS gold determination. No follow-up sampling was completed. For historic RAB drilling completed by Hunter Resources in 1995, derived from WAMEX Report A047408, 4m composite samples were taken within the targeted saprolite clays. Samples were then pulverised and analysed for gold by aqua regia digest method with a carbon rod finish with ASS gold determination. No follow-up sampling was completed. YRL AC drilling was completed with a 3’ 1/4 inch AC blade bit and hammer (where hard conditions prevailed). YRL RC was completed using a 5’ ¼ inch face sampling hammer. For historic RAB drilling completed by Eagle Mining and Hunter Resources in 1995, an industry-standard RAB drill rig and setup were assumed to be used. For YRL 2019-2020 drilling, AC and RC recovery and meterage were assessed by comparing drill chip volumes for individual meters. Estimates of sample recoveries were routinely recorded. Routine checks for correct sample depths are undertaken at the completion of each rod (3m for AC and 6m for RC). AC and RC sample recoveries were visually checked for recovery, moisture and Page 11 Criteria JORC Code explanation Measures taken to maximise sample recovery and ensure representative nature of the samples.

Due to the generally good drilling conditions around the Rosewall Prospect, samples represent the interval drilled. Historical recording of the sample recovery is limited; however, logging data captures sample condition, with only a small percentage of intervals drilling noting damp or wet samples. It was noted in historical logs that some holes failed to penetrate through the hard semi-lithified transported cover. For YRL 2019-2020 drilling, the supervising geologist completed AC and RC drill chip logging at one-metre intervals at the rig. Logging data was captured in Excel spreadsheets and stored in a micromine data file format. It is qualitative in nature. All drilled intervals were logged. For historic RAB drilling completed by Eagle Mining and Hunter Resources in 1995, logging was completed at various intervals based on geological observation and recorded by hand into pre-printed logging forms. These forms were scanned and included in WAMEX report A047408. It was qualitative in nature. All drilled intervals were logged. The total length and percentage of the relevant intersections logged.

ASX Announcement 10 October 2024 • • • • • • • • For YRL 2019-2020 drilling, both AC and RC samples were collected. AC and RC 4m composite samples were collected from the drill rig by spearing each 1m sample pile. Single metres samples were collected for AC drilling by spearing individual metre sample piles. For RC drilling, 1m samples were collected from an onboard cone splitter and placed into a calico bag with a unique sample ID. Samples were collected dry. For YRL AC samples, no duplicate 1m samples were taken in the field. Standards and blanks were routinely inserted into the sample sequence for 4m and 1m samples. For YRL RC samples, field duplicates were collected routinely. Standards and blanks were routinely inserted into the sample sequence for 4m and 1m samples. Duplicate results were acceptable, given the variable nature of orogenic gold mineralisation. YRL AC sample weights were relatively consistent, approximately 2.0-2.5 kg. YRL RC sample weights were relatively consistent, approximately 2.0-3.5 kg. For labs used by YRL, internal lab quality control measures include lab duplicates and the insertion of lab standards and blanks. The sample size is appropriate given the fine to medium-grained size of the sheared dolerite host. For historic RAB drilling completed by Eagle Mining and Hunter Resources in 1995, details of sample methods and quality control measures were not recorded but are assumed to be of an industry standard for the time. It was noted that field duplicates were collected from intervals of interest during the Hunter Resources drilling.

Aurum laboratories QA/QC involves the insertion of internal lab standards using certified reference material, blanks, splits and replicates as part of the in-house procedures. QC results (blanks, duplicates, standards) are aligned with commercial procedures, reproducibility, and accuracy. These comparisons were deemed satisfactory. For YRL 2019-2020 AC and RC drilling 4m composites, one standard was inserted for every 40 samples and one blank was inserted for every 80 samples. For 1m samples, one standard was inserted for every 40 samples, and one blank was inserted for every 80 samples. For historic RAB drilling completed by Eagle Mining, samples were submitted to Genalysis Laboratories in Perth for Au analysis by BETA with a lower detection limit of 1ppb Au. Scans of the original lab reports are retained in the WAMEX report A047408. Internal lab QC protocols are unknown and assumed to be the industry standard for the time. For historic RAB drilling completed by Hunter Resources, samples were submitted to Amdel Laboratories in Perth for Au analysis by aqua regia digest/Carbon rod AA method, with a lower detection limit of 1ppb Au. Scans of the original lab reports are retained in the WAMEX report A047408. Internal lab QC protocols are unknown and assumed to be the industry standard for the time. For YRL drilling, all significant intercepts have been visually verified against the retained AC and RC chip trays, with all significant intercepts showing evidence of shearing, alteration and quartz veining at the expected intervals. Lab and drilling data is stored as PDF scans or Excel spreadsheets on the Company Server in the Perth office. No data was adjusted. No twinned holes have been drilled. For YRL drilling, all intercepts have been previously reported. Significant intercepts were calculated by generating a length-weighted average of sample grades for all intervals greater than or equal to 0.3g/t Au, with no more than 2m of continuous internal waste included unless otherwise stated. For historic drilling, all drilling data has been previously reported. The data is publicly available from WAMEX report A047408. Scanning of original logging and sampling data were reviewed and transcribed into an Excel spreadsheet by Company geologists under the supervision of Mr. Chris Oorschot. Data was then verified by comparing results to original plans and sections included within WAMEX report A047408. Furthermore, several pads from the 1995 drilling program were located in the field and found to be located within 30m of the historic coordinates. Given the low-level nature of the significant results and the lack of historic chips at the drill site, visual verification of results was impossible.

For YRL 2019-2020 AC and RC drilling, all drill collar locations were initially pegged and surveyed using a handheld Garmin GPS, which was accurate to within 3-5m. The topography is mainly flat at the drilling location. No downhole surveys were completed for the AC or RC drilling. For YRL drilling, MGA94 Zone 51 for AC drilling and local grid and AMG coordinates for historic drilling converted to MGA94 Zone 51. The topography is flat, with only minor elevation differences between drill holes. This difference is unlikely to impact geological interpretations materially. A topographic surface from the recently completed ground gravity survey has been used to validate RL’s. For historic RAB drilling completed by Eagle Mining and Hunter Resources, the original AGD84, AMG zone 51s coordinates were transcribed from scans of the o
