Announcement PDF ASX Release 29th August 2024 Narryer Project: 54 m of graphite mineralisation at Ranger • NY001RC intersects 54 m of graphitic mineralisation 198 m – 252 m (eoh) o includes 20 m > 10% visually estimated graphite from 232 m • Hole abandoned in high-grade graphite due to excess water • Assay results expected mid-October • >7 km trend at Oculus is now highly prospective for similar mineralisation Buxton Resources Ltd (‘Buxton’; ASX:BUX) is pleased update shareholders in relation to activities at the 100% owned Narryer Project, in the Murchison region of WA. NY001RC, the maiden Buxton drill hole at the Narryer Project aimed to test a ground EM target at the Ranger Prospect (Figure 1). Graphite mineralisation was intersected at depth as predicted by the EM model (Figure 2). Visual estimates by Buxton geologists indicate that NY001RC intersected continuous graphite mineralisation from 198 metres depth to the end-of hole (Figure 3, Table 1). Continuous high-grade graphite (visually estimated > 10% TGC) was observed from 232 metres to 252 metres depth, at which depth excessive water caused the hole to be abandoned. The rig has now been released, and Buxton will prioritise assaying the mineralised interval for Total Graphitic Carbon (TGC) with results expected by mid-October.

Significantly, the ground EM conductors modelled at the nearby Oculus prospect are now most likely to be related to similar graphitic mineralisation. These conductors have been confirmed to be legitimate bedrock conductors by modelling of Buxton’s recent ground EM survey data (see ASX Announcement 22 May 2024). The related airborne EM conductivity trends extend over >7 linear / strike kilometres around the Oculus Prospect (Figure 4) and define a relatively simple fold structure. Buxton has commenced modelling “early time” ground EM data to determine the potential for up-dip / shallower extensions to the drill-confirmed graphite mineralisation at Ranger and the EM models at Oculus will be similarly revisited. The current models are based solely on mid-late time EM channels (standard practice for targeting sulphide mineralisation). Planning works for Loupe EM and Heritage surveys at Oculus are also underway. Buxton has successfully utilised the Loupe EM surveying method to target recent RC drilling at Graphite Bull (see ASX Announcement 23 October 2023). Figure 2: Narryer Project - Ranger Prospect cross section looking east-northeast. Modelling of early time EM channels will assess potential for the graphite mineralisation to extend closer to surface than the current model (based on late time channels) indicates.

This discovery by Chalice Mining Ltd and the presence of numerous Ni-Cu-PGE occurrences along a >1,000km strike length defines the West Yilgarn Ni-Cu-PGE Province. In addition to Ni-Cu-PGE prospectivity, Buxton has also now identified that the Narryer Project has potential for graphite and carbonatite-related Rare Earth Element (REE) style deposits and regolith-hosted REE within both Proterozoic and Archean successions. During 2021 & 2022, Buxton completed ground reconnaissance, a regionally extensive 1-km spaced ground gravity survey and a highly targeted 2566.6-line km Airborne EM survey. Interpretation of the AEM data has identified multiple high priority anomalies, three of which warranted immediate followup by moving loop EM, which was completed at Bandito, Prodigy and Ranger Prospects in early 2023. Additional soil sampling was conducted over AEM targets in late 2003 which provided encouragement to extend the Ranger ground EM coverage to the nearby Oculus Prospect, which hosts a large eye-shaped conductivity feature. The recent RC drilling at Ranger indicates that the high-conductance ground EM target at Ranger is caused by thick graphite mineralisation with visually estimated high-grades (>10% TGC). Future exploration will test if the extensive conductors at the nearby Oculus Prospect are also related to similarly thick, high-grade graphite mineralisation. Figure 5: Buxton’s Graphite Bull & Narryer Projects are located within the Gascoyne / Murchison Region of Western Australia and are readily accessible year-round.

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 commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. Reverse Circulation drilling was completed using standard industry best practice. 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). Reverse Circulation (RC) drilling was undertaken by by Topdrill PL using a Schroamm T685 truck mounted rig (RC). 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. RC recoveries were considered good with available air for drill sample recovery being deemed adequate for the ground conditions and depth of sampling undertaken. 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. Reverse Circulation drilling produced samples that were collected at one-metre intervals. A one metre ‘split’ sample was collected in pre-numbered calico bags at the time of drilling using a cone splitter integrated into the drill cyclone to produce an approximate 1.5kg sample, which is considered representative of the full drill metre. The residual material from each metre interval was collected in 600mm x 900mm biodegradable bags preserved at the drill sites whilst laboratory analysis is ongoing. Drill samples selected for analysis were limited to those containing visible graphite (using the one metre split samples) alongside composites containing either a two, three or four-metre buffer either side of the visible intervals. Analyses will be undertaken by ALS Geochemistry in Perth and include Total Graphitic Carbon with other parameters as necessary. Appropriate measures have been undertaken to maximise sample recovery and ensure the representative nature of samples, including: - Terminating RC holes when recovery amounts are reduced at depth Terminating RC holes when excess water is encountered No apparent relationship has been defined between sample recovery and grade based on the various drilling programs to date at Graphite Bull. 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. Chip trays were collected from each one metre interval this was used to log lithology, oxidation and visual graphite content estimate a streak test was used to assist with visual estimates alongside historical samples. Visual estimates for TGC were based on comparison with historic samples from Buxton’s Graphite Bull Project, YBRC0018 and YBRC0019 which constituted 276 metres of previously assayed material with grades from 0.1% to 30.9% TGC. This included 52 samples greater than 10% TGC. 19 samples from 5-10% and 87 samples from 0-5%. Samples were noted if they were wet or where recovery was significantly impacted. Photographs of all RC chip trays will be taken at BUX’s core processing facility at the Project, and in Perth and PO Box 661 Nedlands WA 6009 15 Robinson Av Belmont WA 6104 T: 08-9380 6063 E: info@buxtonresources.com.au W: www.buxtonresources.com.au Visit our investor hub: investorhub.buxtonresources.com.au retained on file with the original chip trays stored at BUX’s storage facility in Peth. 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. Logging is considered to be semi-quantitative.

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. Whether sample sizes are appropriate to the grain size of the material being sampled. Quality of assay data and laboratory tests Verification of sampling and assaying The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. Not applicable, the release does not include laboratory assay results. For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. See ASX announcement 13th October 2022 for details relating to the airborne EM and ASX announcement 22nd May 2024 for details relating to the ground Moving Loop EM. Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. In addition to duplicate samples (detailed above), Quality Control and Quality Assurance (QA/QC) procedures included insertion of standards (three different standards each certified for TGC at three different abundance levels appropriate for the expected abundances of mineralisation intersected in the drill program) and blanks which were inserted every 20 samples. The verification of significant intersections by either independent or alternative company personnel. Senior company geological personnel onsite for the entirety of the drilling and logging process. The release does not include data from other geophysical or handheld XRF tools. Once the core is processed at BUX’s core processing facility in Perth. The logging will be validated by a BUX on-site geologist and compiled onto the BUX MX Deposit drill hole database Assay data will be imported directly from digital assay files from contract analytical company ALS (Perth) and merged in the Company MX Deposit drill hole database.

Specification of the grid system used. Quality and adequacy of topographic control. Data spacing and distribution Data spacing for reporting of Exploration Results. 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. The measures taken to ensure sample security. Sample security Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied. Logging and sampling were recorded directly into a digital database. Not applicable, the release does not include laboratory assay results. The surface hole collar location was surveyed using a handheld Garmin GPS unit with an expected accuracy of ±6m for easting and northing with elevation also recorded. Drill path gyroscopic surveys were at 0m and at subsequent 30m downhole intervals to final hole depth using an Axis Gyro tool. All surface surveying was completed using a handheld GPS to MGA94 / Zone 50 South grid system. Topographic control was provided by a Digital Elevation Model (DEM) derived from the SRTM dataset which provided a DEM with a +/- 3.5m vertical accuracy (Elsonbaty et al 2023). This is deemed adequate for first-pass exploration drilling, particularly given that topographic relief is extremely low. See drill tables for drill hole location. Only a single hole has been drilled at the Ranger prospect, and so this spacing and distribution is not considered suitable for mineral resource estimation. The orientation of the drilling is not expected to introduce sampling bias. All drill holes have intersected the mineralisation at a sufficient angle to the strike and dip of the mineralised units. The chain-of-sample custody is managed by the BUX staff from collection at the rig to the submission of the samples to ALS Limited – Perth for analysis. Samples are being stored at the drillsite before being transported and processed at BUX’s secure sample processing and storage facility in Perth. The diamond drill core will be wet cut using a diamond blade and sampled at BUX’s core processing facility in Perth by BUX staff and contractors. Diamond drill core samples will be placed in prenumbered calico bags and further secured in green plastic sample bags with cable ties. The samples are further secured in a bulk bag and delivered to the ALS Perth by contractor freight service. Sample reconciliation advice is sent by ALS-Perth to BUX’s Geological Database Administrator on receipt of the samples. Any inconsistences between the despatch paperwork and samples received is resolved with BUX before sample preparation commences. Sample preparation and analysis is completed at one of the ALS laboratories in Perth.

BUX have a 100% interest in exploration license E09/2027, E09/2028, E09/2029 and E09/2722 which cover 452 km2. No royalties encumber these tenements. Native Title is held by the Wajarri Yamatji native title determination and claim covers approximately 100,701 square kilometres of land in the Yamatji region. Horizon Heritage Management (Horizon Heritage) was engaged by Heritage Link to facilitate and undertake an AHA Work Program Clearance Aboriginal heritage survey with Wajarri Yamatji (Simpson) Traditional Owners for the Narryer – Ranger Prospect survey area. A review of the Department of Planning, Lands and Heritage (DPLH) online ACHIS identified no Aboriginal sites or places within the Narryer – Ranger Prospect survey area. Exploration done by other parties Geology The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. Acknowledgment and appraisal of exploration by other parties. Deposit type, geological setting and style of mineralisation. The eastern portion of the Narryer Project lies within the Radio Quiet Zone of the Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory. The RQZ does not cover the Ranger or Oculus Prospects. The tenement is in good standing with DMIRS and there are no known impediments for exploration on this tenement. Numerous exploration parties have held portions of the area covered by BUX tenure previously. No substantive historical exploration for graphite has been undertaken. No other parties were involved in the exploration program that generated data that was used in this release. The Narryer Project area is located on the north western margin of the Yilgarn Craton. The surface geology of the Narryer Project is dominated by tertiary lateritic weathering profiles and TertiaryQuaternary drainage basin sediments that largely obscure the basement geology. Basement geology consists of Archean rocks of the Narryer Gneiss Terrane and, in the far northwest, the late Mesoproterozoic - Neoproterozoic Badgeradda Group. These two distinct geological terranes are juxtaposed along the Meeberie fault. The Narryer Gneiss Terrane is composed of a tectonically interleaved and poly deformed mixture of granite, mafic intrusions and metasedimentary rocks in excess of 3.3 billion years old, with the majority in excess of 3.6 billion years old.

The Narryer Gneiss Terrane is divided into four major rock sequences (Myers 1990); the Dugel Gneiss, Meeberrie Gneiss, Manfred Complex, and unassigned polydeformed leucocratic gneisses and metasediments. Graphite mineralisation is hosted by quartz-felspathic and hornblende gneisses and chloritic schists that are most likely from the Mount Narryer gneissic complex. The hornblende gneiss gradually included slivers of graphite which in turn became massive.
