The headline result from 26IWBRC0120 represents the highest-grade interval returned to date within the IWB Gold Project. These new results, combined with previous intercepts on the 6,550mN section, located 100m south, indicate the potential for an additional domain of high-grade gold mineralisation within the Arrakis mineralised structure. Further results and additional drilling will be required to confirm the geometry and continuity of the newly identified high-grade domain. The results from 26IWBRC0119 have also returned the shallowest intercept to date at Arrakis, approximately 26m below surface. Diamond core samples from 26IWBRC0121D located approximately 60m down-dip of the 26IWBRC0120 intercept are anticipated in late August.” Yandal Resources Ltd (ASX: YRL, “Yandal Resources” or the “Company”) is pleased to provide an exploration update for the Arrakis Prospect within the Ironstone Well-Barwidgee (IWB) Gold Project (see Figures 4 and 5). Targeted broad-spaced infill RC drilling on 100m spaced drilling lines within the currently defined 1.3km Arrakis discovery commenced in early May. The drilling was designed to test for high-grade domains within the 1.3km striking Arrakis mineralised system. Results from the nine RC holes between the 6,450mN and 6,850mN drill lines have been received and reported below (see Tables 2, 3). Assay results include several significant intercepts, including the highest-grade intercept returned to date within the IWB Gold Project from 26IWBRC0120, located on the 6,650mN section (see Figure 1). Results demonstrate the potential for an additional high-grade domain (see Figure 2) within the Arrakis gold discovery. Results from a further ten holes (Figure 2), including three RC holes with diamond core tails, are anticipated throughout August. A maiden exploration target for the Arrakis discovery is scheduled in Q3 CY26. yandalresources.com.au | ASX:YRL 3 Figure 1: Arrakis 6,650mN cross-section showing all recently received drilling results, including significant intercepts from 26IWBRC0119 and 26IWBRC0120.

Further drilling is needed to assess if such a process has occurred. yandalresources.com.au | ASX:YRL 5 Results from the Arrakis 6,650mN section (Figure 1) demonstrate several significant intercepts occurring on the footwall of the intermediate porphyry, which is commonly associated with lower-grade mineralisation more broadly across Arrakis. The significant intercept from 26IWBRC0120 occurs directly below an intermediate porphyry, and is hosted within a partially weathered, heavily deformed dolerite with minor quartz veining. The diamond core tail of 26IWBRC0121D intercepts this equivalent position approximately 60 m down-dip within fresh rock, with samples currently at the lab for analysis. Results from 26IWBRC0119 and 26IWBRC0120, combined with previously reported intercepts from 25IWBRC0042 (see ASX release 24 September 2025) that intercepted 50m @ 1.3g/t Au, including 28m @ 1.9g/t Au, indicate an additional high-grade domain within the 1.3km striking Arrakis system (see Figure 2). Further results, along with additional drilling, are required to confirm this interpretation. Several intercepts outside of the main Arrakis structure have also been intercepted, including: o 2m @ 3.6g/t Au from 139m in 26IWBRC0115 o 13m @ 0.5g/t Au from 139m in 26IWBRC0115 (ETW*1 10m) o 6m @ 0.7g/t Au from 139m in 26IWBRC0117 In all instances, these intercepts are located within either weathered or partially weathered rock, with no significant intercepts down-dip within the equivalent fresh rock position. This suggests the mineralisation is secondary in nature. Results from a further ten (10) RC holes, including three with diamond core tails, are yet to be received. Results are anticipated throughout August. A heritage survey completed across the Arrakis Prospect in July will enable further infill drilling on 50m spaced lines across the full extent of the Arrakis discovery. yandalresources.com.au | ASX:YRL 6 Figure 2: A longitudinal section displaying intercept midpoints within the main Arrakis mineralised structure (intercepts from subordinate structures are excluded).

The prospect is defined by a > 2.2 km regolith gold anomaly defined by air-core drilling in 2025. The prospect lies beneath 4-20m of transported cover. The depth of weathering varies along strike, with the base of fresh rock typically between 80-120m from surface. To date, primary fresh rock mineralisation has been defined over more than 1.3km of strike, with true widths ranging from 4m to > 30m. Arrakis mineralisation is hosted within a deformed porphyritic dacite intrusive that varies in thickness both along strike and down-dip. The intrusive appears to be intruding parallel to stratigraphy (stratiform), possibly along a narrow sedimentary horizon between two mafic units. Steep north-east dipping mineralisation hosted within the intrusive is bracketed by a sequence of pillow basalts to the east and a dolerite unit to the west. A compilation of RC and diamond drilling results and geological observations demonstrates two separate styles of mineralisation at Arrakis: • A broad lower-grade style of mineralisation hosted within a silica-sericite altered dacite porphyritic intrusive unit that has been weakly to moderately fractured. The chlorite- biotite-filled fractures also contain pyrite and minor arsenopyrite. Fine pyrite and arsenopyrite are also disseminated throughout the altered intrusive host. This style of mineralisation is often associated with wider zones of mineralisation. • A second style of higher-grade mineralisation is associated with a more intense level of brittle-ductile deformation and strong silica-pyrite-arsenopyrite alteration of the dacitic porphyry margins, often presenting as a clast-supported breccia is pervasively silica- altered. This style of mineralisation can also be sheared and intercalated (mixed) with the bounding basalts and dolerites. Structural observations from diamond drilling indicate strong strike-slip, sinistral shearing. Mineral lineations broadly plunge shallowly to the northwest. Two dominant ductile shear fabrics have been observed: a subparallel fabric and a shallower-dipping, northwest-striking fabric. The latter often exhibits as a mylonite and may offset or structurally control mineralisation. The position of the dacitic intrusion and the thickness of the higher-grade mineralisation are likely to be structurally controlled. yandalresources.com.au | ASX:YRL 10 About Yandal Resources Limited Yandal Resources has a portfolio of advanced gold exploration projects in the highly prospective Yandal and Norseman-Wiluna Greenstone Belts of Western Australia. Ironstone Well-Barwidgee Gold Project The 100% owned Ironstone Well-Barwidgee (IWB) Gold Project covers approximately 456km² of highly prospective and under-explored tenure located between the Jundee and Bronzewing mines in the northern Yandal Greenstone Belt. Yandal has an established Resource of 268,000oz of gold at Flushing Meadows (within IBW) and considers there to be strong potential to make new discoveries and expand this resource base within its extensive tenure holding. (Refer to the ASX announcement of 4 November 2020 and Table 1 for details of the Flushing Meadows Resource). The IWB project area also includes two new gold discoveries, the Arrakis and Siona Prospects, both made within the last twelve months. These outcomes were driven by the execution of a targeted exploration program that followed a systematic, geologically driven strategy that was developed in early 2023. The Arrakis Prospect is hosted within the Caladan fold, and the Siona Prospect is hosted within the New England Granite. Both discoveries are currently at an early stage but progressing well, with future activities focused on delineating the scale of each of the newly defined mineralised systems. The IWB Gold Project also includes several advanced prospects, where limited historic and YRL drilling has returned robust gold intercepts, indicating the potential for shallow oxide mineralisation. Both the early- stage and more advanced prospects are the focus of ongoing exploration. Mt McClure The Mt McClure Gold Project, acquired in August 2022, is located ~15 km southwest of the historic Bronzewing Mine and includes three mining leases with JORC 2012 Resources totalling 182,200oz Au. The project has prospectivity for new shallow gold deposits adjacent to current Resources and in the footwall and hanging wall of the stratigraphy. Ground gravity survey data support ongoing structural/stratigraphic interpretations for 2026 targeting. yandalresources.com.au | ASX:YRL 11 Figure 4: Yandal Resource exploration Project locations within the Yandal Greenstone Belt.

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. • Yandal Resources has completed RC drilling across both 100m lines covering the Arrakis Prospect, where primary gold mineralisation has been identified along 1.3km of strike • . The drilling involved a 139mm face sampling bit down to between 140m and 286m. Holes were drilled at an angle of -60 ° to the southwest or northeast. • 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 a 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. • Please note: Where very high concentrations of gold occur, the down-hole length of the intercept can be artificially increased due to smearing of gold particles across sample intervals either during the process of drilling or preparation for analysis. Further drilling is needed to assess if such a process has occurred. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • 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
