The hole intersected pyritic, graphitic metasediments (Figure 1) from 505 m to end of hole. Graphite had not been observed previously at Madman. Graphite is a highly conductive material, and the Company interprets this unit as the source of the off- hole conductor modelled from downhole electromagnetic surveying of MD002DD and MD003DD (ASX, 1 Sep and 7 Oct 2026), supported by the modelled conductor plates lying broadly parallel to bedding measured in the graphitic metasediments. Rare vein-hosted sulphide was observed as thin (up to 5 cm) quartz-sulphide bearing veins (Figure 2), along with wider (0.2 – 1.2 m) zones of quartz vein stockworks having trace sulphide (Figure 3). Core logging and sampling are in progress, with assay results expected in December 2026. Buxton is continuing preparations for a range of field activities including airborne magnetics and drilling in Arizona, and the Company will provide further updates in this respect in the coming weeks. Buxton Managing Director Marty Moloney commented: “The graphitic sediments in MD004DD provide an explanation for the off-hole conductor detected from downhole EM surveying. We will now complete field activities at Madman, undertake assaying and detailed logging and integrate the results over the Australian summer. In the meantime, we will turn our attention to Arizona where we’re preparing for geophysical and drilling programs over the upcoming winter field season.” 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 View online: https://buxtonresources.com.au/link/y14XaP ASX:BUX Figure 1: MD004DD NQ3 core (core is 45 mm width) at ~567 m depth showing dark, fine-grained, metasedimentary lithology with graphite developed along fractures and shear planes.

Buxton has improved the last ~6 km of this seismic line, then established 56 km of new access tracks (Figure 6). Buxton’s maiden drilling program was undertaken in July and August 2026 and comprised two diamond exploration holes, MD002DD and MD003DD, together with a water bore MD001WB. Both exploration holes were drilled through the Officer Basin cover sequence and into the underlying basement, and both intersected zones of quartz-carbonate veining, brecciation and sulphide mineralisation within that basement, with the veining extending into the basal part of the Skates Hills Formation conglomerate. Magnetite-bearing gneiss towards the base of each hole provides a plausible geological explanation for the magnetic anomaly that defined the initial target. Assay and logging results for MD002DD, reported on 20 August 2026, describe a zoned hydrothermal system rather than a single mineralised interval: a potassic alteration zone carrying a coherent bismuth-uranium-molybdenum-lead-copper pathfinder association, an overlying argillic zone, a distal lead-zinc-silver halo, and an anomalous gold-copper-bismuth interval in the lower part of the hole. Buxton’s interpretation is that MD002DD intersected the peripheral alteration envelope of a large system rather than its centre. That interpretation, together with the position of the modelled conductor outside both maiden holes, was the basis for drilling MD004DD. Background to MD004DD Downhole electromagnetic surveying of MD002DD identified a discrete conductive response approximately 350 m north of that hole. Downhole electromagnetic surveying of MD003DD, completed from two separate surface transmitter loop positions, confirmed the same off-hole response, which was modelled approximately 250 m north-northeast of MD003DD (ASX, 1 September 2026). MD004DD was collared at the MD003DD drill pad and designed to intersect the modelled plate solutions between approximately 600 m and 700 m downhole (Figures 4 and 5, Table 1). Electromagnetic plate modelling is non-unique. The plates shown are alternative solutions that each independently satisfy the same measured response — they are not separate conductive bodies. Modelled plate size and conductance trade off against one another, with smaller plates requiring higher conductance to fit the data, and modelled conductance values should not be read as measurements of the conductivity of any physical body. Modelled plate dimensions range from approximately 400 x 400 m to 1,000 x 1,000 m, with moderate modelled conductances of approximately 400 to 1,000 Siemens. Plate orientation resolves consistently as striking northwest and dipping 55 to 75 degrees to the southwest, interpreted to reflect structural control. Responses of this character may be produced by sulphide, graphite, magnetite, saline groundwater or conductive lithologies, and no 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 View online: https://buxtonresources.com.au/link/y14XaP ASX:BUX inference as to the presence, size, tenor or continuity of sulphide mineralisation should be drawn from the plate models. MD004DD intersected graphitic sediments from 505 m, approximately 95 m above the shallowest predicted plate intersection, and was terminated at 627.20 m, within the predicted 600–700 m intersection window. The Company interprets the graphitic sediments as the source of the modelled response; the difference between the predicted and intersected depths is within the uncertainty expected of plate modelling. The cross section (Figure 4) also illustrates a marked thickening of the Skates Hills Formation conglomerate (SHFC), which is over four times thicker in MD003DD than in MD002DD across only ~200 m of lateral separation. The top of the conglomerate is essentially flat between the two holes while its base steps down by more than 100 m. Those relationships are more readily explained by fault displacement than by depositional drape or erosion, and place a structure between the two holes. Buxton’s working interpretation is a releasing step in a strike-slip fault system rather than a simple half-graben based on preliminary bedding orientation measurements. MD004DD intersected no SHFC: the Mundajini Formation gypsum member rests directly on basement at 494.4 m, approximately 230 m north- northeast of where MD003DD intersected 148 m of conglomerate. This abrupt pinch-out indicates a second, northern boundary to the conglomerate-filled depression, which is being incorporated into the structural model. On either interpretation the structure provides a plausible conduit for the hydrothermal fluids logged in both maiden holes. Detailed structural logging is continuing.

These examples should not be taken as limiting the broad meaning of sampling. MD004DD was drilled by diamond coring below a mud rotary pre-collar, providing continuous HQ3 and NQ3 core over 122.8–218.6 m and 351.6 m to end of hole at 627.20 m No samples from MD004DD have been submitted for laboratory analysis at the date of this Announcement and no assay results are reported. The observations reported are visual, from geological logging of the core. Sampling of selected intervals, including the graphitic sediments, is in progress. Calibration of measurement tools: magnetic susceptibility measurements were acquired with a Terraplus KT-10 v2 instrument, checked against the manufacturer's calibration standard at the start and end of each logging session. Portable XRF measurements were acquired with Olympus Vanta and Thermo Niton XLT3+ GOLDD instruments, each subject to the manufacturer's internal energy calibration on start-up and verified against certified reference materials at the start and end of each session. pXRF results are used for lithological and pathfinder discrimination only and are not reported as assay-grade data. Core orientation was undertaken with a Reflex ACTx tool; orientation confidence was recorded per run and orientation marks were rejected where confidence criteria were not met. 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-sampling bit or other type, whether core is oriented and if so, by what method, etc). MD004DD was drilled by McKay Drilling Pty Ltd using a truck-mounted diamond rig (MKY023), with a mud rotary / rock-roller (PCD) pre-collar followed by HQ3 and NQ3 diamond coring as follows: mud rotary / rock-roller 0–122.8 m; HQ3 coring 122.8–218.6 m; rotary (HQ rotary, tricone) 218.6–351.6 m; HQ3 coring 351.6–488.3 m; NQ3 coring 488.3–627.20 m. All HQ3 and NQ3 core runs were oriented using a Reflex ACTx tool. Core diameters are HQ3 61.1 mm and NQ3 45.0 mm. The hole was terminated at 627.20 m, short of its planned depth of 800 m, after intersecting graphitic sediments that were interpreted to account for the conductor being targeted. Drilling of MD002DD and MD003DD was described in the ASX Announcement of 7 October 2026. Drill sample recovery Method of recording and assessing core and chip sample recoveries and results assessed. Mud rotary pre-collar samples were collected as described for MD002DD and MD003DD (ASX, 7 October 2026). Recovery and sample quality are very poor and these samples are used for visual logging only. Diamond core recovery is recorded per run during mark- up by qualified geologists. For MD004DD, 367.36 m was recovered from 371.40 m cored (98.9%) over the cored intervals 122.8–218.6 m and 351.6–627.2 m. Recovery across the basement (494.4 m to end of hole) is 99.4%, 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.

Recovery is below 90% in four runs, all in the Officer Basin cover sequence (215.3–218.3 m, 440.3–443.3 m, 455.3– 458.3 m and 488.3–489.2 m); the largest single loss is 0.85 m over 440.3–443.3 m. As for MD002DD and MD003DD, 46 runs record measured core exceeding the drilled run length, attributed to core block depth marking, and recovery has been capped at 100% per run. No assay results are reported, so no relationship between sample recovery and grade is assessed. 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. Geological logging is qualitative to semi-quantitative, comprising lithology, alteration, veining, mineralogy and estimated sulphide abundance recorded digitally, together with magnetic susceptibility. Core is photographed wet and dry. MD004DD core logging is in progress. The graphitic sediments are described from visual logging; no estimate of graphite content has been made. 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. No sub-sampling of MD004DD core for laboratory analysis has been undertaken at the date of this Announcement. Samples will be prepared and quality-controlled as described for MD002DD and MD003DD (ASX, 7 October 2026): core sawn in half along its long axis, half core submitted for analysis, and certified reference materials, blanks and quarter-core field duplicates inserted into the sample stream. 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. Whether sample sizes are appropriate to the grain size of the material being sampled.

Specification of the grid system used. All figures are presented in GDA2020, MGA zone 51. Quality and adequacy of topographic control. The quality of topographic control is deemed adequate for the reconnaissance nature of the results presented. Data spacing and distribution Data spacing for reporting of Exploration Results. Not applicable – this Announcement reports geological observations from a single drill hole. No sample compositing has been applied. 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. 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. MD004DD was drilled at -68.5° toward 013.6° (Table 1), designed to intersect the modelled conductor plates, which strike northwest and dip 55–75° to the southwest. Bedding measured in the graphitic metasediments (n = 12, mostly low orientation confidence) has a mean orientation of approximately 64° toward 225°, broadly parallel to the modelled conductor plates, and is intersected by the hole at approximately 35–50° to the core axis. The true thickness of the graphitic sediments is not known, and the downhole interval may not represent true thickness. 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. MD004DD core is stored at the drill site pending transfer to Buxton’s secure facility in Belmont, Perth where logging and sampling will be finalised. The chain of custody is managed by Buxton staff from collection at the rig to submission to the laboratory. The risk of deliberate or accidental loss or contamination of samples is considered very low, particularly given the remote location of the project. Audits or reviews The results of any audits or reviews of sampling techniques and data. No Project-specific external audits or reviews have been undertaken.
