For further information or to ask questions concerning this announcement, please visit our Investor Hub at: https://investorhub.yandalresources.com.au/link/2P2Kwy Commenting on the new results, Yandal Resources’ Managing Director, Mr Tim Kennedy, said: “Despite challenging drilling conditions, the team and our drilling partners were able to complete a majority of the planned program successfully. With the increased number of fresh rock intercepts, the Company’s geological understanding of the prospect has grown substantially with each completed RC hole. The widths and strike extent of the relatively rigid chlorite-magnetite altered unit observed in this phase of drilling is very encouraging. We look forward to receiving and interpreting results in the coming weeks.” Registered Address Board Members Gold Projects Yandal Resources Limited Tim Kennedy Managing Director/CEO Greg Evans Non-Exec Chairman Katina Law Non-Exec Director Chris Oorschot Technical Director Greg Fitzgerald Company Secretary T +61 8 9389 9021 E yandal@yandalresources.com.au W www.yandalresources.com.au Ironstone Well (100% owned) Barwidgee (100% owned) Mt McClure (100% owned) Gordons (100% owned) Shares on Issue 234,726,156 Share Price $0.090 Market Cap $17.4M ASX Code YRL ACN 108 753 608 A P ABN 86 108 753 608 Level 1, U5/62 Ord Street West Perth WA 6005 PO Box 1104 Nedlands WA 6909 Yandal Resources Ltd (ASX: YRL, “Yandal Resources” or the “Company”) is pleased to advise that the phase 2 Reverse-Circulation (RC) drilling program across the Oblique Prospect (E 53/1882) is complete. The Oblique Prospect is part of the Company’s 100% owned Ironstone Well-Barwidgee Gold Project, located within the Yandal Greenstone Belt of Western Australia, situated between the Jundee and Bronzewing Operations. The program follows up on results from an initial RC campaign undertaken in September, which confirmed the broader prospectivity of Oblique. Oblique comprises a broad regolith gold anomaly associated with a magnetic high and has a target footprint with a strike extent of more than 1.9km based on historic shallow drilling. Program Summary A total of 14 RC holes and three RC re-entries were completed for 2,574m of drilling testing along an overall strike length of 1.2km (see Table 1 and Figure 2). Hole depths ranged between 72m and 270m, with numerous fresh rock intercepts attained within and around the targeted magnetic stratigraphy. This RC program builds on the results from RC drilling completed in September 2023 (see ASX Release of 25th October 2023). The program aimed to: • Further test mineralisation within the currently defined Exploration Target extents, • Test for mineralisation 400m south of previous RC drilling and • Obtain several intercepts of mineralisation within fresh rock. The drilling combined with magnetic susceptibility data has resulted in a revision of the interpreted host package from silica-rich sediment to a broad 20-35m wide chlorite-magnetite altered volcaniclastic unit. Drilling has reaffirmed this same unit as the source of the Oblique magnetic anomaly (See Figure 2). The unit appears laterally continuous with local fluctuation in the magnetic response observed, including de-magnetised zones. All samples have been dispatched to the lab for analysis, with results expected between late December 2023 and early January 2024. Ironstone Well-Barwidgee Lithium Review An initial review of the pegmatite-hosted lithium prospectivity across the Ironstone Well-Barwidgee Project has been completed. The review identified several broad areas of interest, with a regional program designed to assess these areas commencing with the completion of a small orientation soil sampling program in mid-November and the delineation of several areas for field reconnaissance in early 2024. The results of the orientation soil sampling program are expected in early 2024.

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. • • A total of 14 Reverse Circulation (RC) holes and three RC re-entries have been drilled across the Oblique Prospect for a total of 2,574m. Drill holes vary in depth from 72m to 270m. Yandal Resources (YRL) RC Samples were collected via a rig-mounted static cone splitter, splitting approximately 12.5% of the total sample. Two splits are collected for each metre: a primary sample and a duplicate sample. The primary 1m samples are then sent to a lab for further analysis. While the duplicate samples are retained on-site unless submitted as a routine duplicate. For all YRL RC drilling, magnetic Susceptibility measurements were collected at one-metre intervals downhole utilising a KT-10 instrument. 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 metre drilled: a primary sample 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. No calibrations were applied to magnetic susceptibility data collected from YRL RC drilling. RC drilling was used to obtain 1m samples from which a portion, between 1-3kg in weight, was 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. No results have yet been received. Intervals of high magnetic susceptibility were verified by the supervising geologist. • For YRL RC drilling, a 139mm diameter face sampling bit and hammer was used. • • 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 (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- ASX Announcement 8 December 2023 • • Page 9 Criteria JORC Code explanation Commentary 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. • 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. 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. • • • • • • • • • For YRL holes, RC drilling recoveries are visually assessed by the supervising geologist, and any lowvolume 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. For deeper holes, larger drilling equipment is used, with boosted air pressure, to ensure samples are recovered, and groundwater is reasonably controlled. Based on current data, no grade bias is associated with lower/higher volume/weight samples. There have been some wet or damp samples received from RC drilling across Oblique Prospect in the most recent program. 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 mineralisation. All 1m samples are wet-sieved and retained in labelled and annotated chip trays. Chip trays are stored on-site for review and transported to Perth for long-term storage. The quality of logging information is considered sufficient to support appropriate 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 rigmounted cyclone. Two 1-3kg sub-samples are collected into calico bags labelled with a unique alphanumeric ID. Most samples collected were dry; however, a higher proportion of samples were returned wet towards the end of deeper holes. 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 pulverised to nominally 85%, passing 75µm. Best practice preparation (comparable to the above) is assumed for historic RC drilling. Repeat analysis of pulp samples occurs across 5% of all submitted YRL samples. Field duplicates are routinely collected at an initial rate of 1 duplicate for every 20 samples collected. Sample sizes are considered appropriate given the fine to medium-grained nature of the sampled material. The average weight of 1m samples after the most recent RC program was 1.7kg. Whether sample sizes are appropriate to the grain size of the material being sampled.

Specification of the grid system used. Data spacing and distribution • Quality and adequacy of topographic control. • • Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity ASX Announcement 8 December 2023 For YRL RC Drilling, RC samples will be assayed using a 50g fire assay with AAS (atomic absorption spectroscopy) finish for gold analysis with a 0.01ppm detection limit by Aurum Laboratories in Beckenham, Western Australia. This is considered a total digest and appropriate for the targeted style of mineralisation. 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 un-identifiable by the lab when received. QAQC performance is monitored upon receipt of each batch of results and 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 once all samples for a program are received. For all YRL RC drilling, magnetic Susceptibility measurements were collected at one-metre intervals downhole utilising a KT-10 instrument. No calibrations were applied to the data collected. Intervals of high magnetic susceptibility were verified by the supervising geologist. Significant intercepts from YRL RC drilling will be 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. For YRL RC Drilling, primary sampling and logging data are entered into .xlsx spreadsheets and retained on the company server located in the Perth office. The data is validated and imported into the YRL cloud-hosted MX Deposits Database. The first assay result for each sample is used for the reporting of significant intercepts, and no adjustments have been made to the assay data. Intervals of high magnetic susceptibility were verified by the supervising geologist using a swing magnet to confirm the presence of magnetic minerals within the interval. All drill collar locations were initially pegged and surveyed using a handheld Garmin GPS, accurate to within 3-5m. Completed collars are then surveyed by a licensed surveyor using a DGPS device accurate to <0.1m. All holes were downhole surveyed using a gyroscopic survey tool producing azimuth readings relative to true north that is then converted to UTM MGA94 Zone 51s. All spatial data presented is relative to UTM MGA94 Zone 51s. All YRL collars were surveyed by DGPS, and topographic measurements are of high quality and precision for use in Mineral Resource Estimation. DGPS collars have also been used to generate a topographic surface model. The terrain around the prospect area is relatively flat, with no severe changes in topography. Holes were variably spaced so as to allow an assessment of the program's aims. At Oblique, the line spacing was variable; however, the aim was to complete drilling on an approximate 50m by 50m spacing. All collar details/coordinates are supplied in Table 1. Page 11 Criteria JORC Code explanation Commentary appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. Orientation of data in relation to geological structure Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. • Sample security The measures taken to ensure sample security. • Audits or reviews The results of any audits or reviews of sampling techniques and data. • The hole/data spacing and distribution given for RC drilling completed at Oblique is sufficient to establish a preliminary assessment of the degree of geological and grade continuity; the current spacing of intercepts is not appropriate for estimating a Mineral Resource. No results are reported within the announcement. For Oblique RC drilling, the orientation of all sampling is at a high angle to the main mineralised trend and the orientation of stratigraphic horizons. Drill holes have been drilled on a -60-degree angle perpendicular to the interpreted strike of mineralisation and stratigraphy. The mineralisation geometry is assumed to be relatively simple and planar (based on interpretations using previous drilling, new results, and comparisons to adjacent mined deposits). As such, the sampling orientation is believed to be appropriate and unbiased. Several structures are cross-cutting the interpreted host, and there may be local variations in the geometry of mineralisation; the impact of such structures is poorly understood due to the early-stage nature of the prospect. For Oblique, the drilling orientation relative to the geometry of mineralisation and stratigraphy is unlikely to produce a material sampling bias as sample lengths are interpreted to be close to the true width; however, there are a number of structures cross-cutting the interpreted host, and there may be local variations in the geometry of mineralisation. These structures will be considered as results are received. All YRL samples were collected on-site under the supervision of the supervising geologist. Calico bags are tied, grouped into larger poly-weave bags sealed with cable ties, and then placed into sealed bulker bags. The labelled bulker bags are then transported to Perth directly to the laboratory for analysis via a commercial freight company or YRL geologists. Where a commercial freight company is used for transport, consignment notes and confirmation of receipt by the lab were monitored. Logging, sampling and QAQC protocols were reviewed by the YRL exploration manager in the field while drilling was in progress. The review concluded that logging, sampling and QAQC protocols/methods were satisfactory and of industry standard. • • The procedure for collecting magnetic susceptibility data was monitored throughout the YRL RC drilling program by the supervising geologist. No lab audits have been commissioned but are scheduled prior to any further work being completed.
