Announcement PDF ASX Release ASX:BUX & BUXO 22 July 2025 Centurion Drill Program Nears Key Basement Target Buxton Resources Ltd (ASX: BUX & BUXO, ‘Buxton’) advises the market that drilling activities at its Centurion Project have progressed to a depth of 404 metres, with preliminary geological signs suggesting proximity to the interpreted basement target. While the first hole, CN001DD, was unable to continue beyond this depth due to localised ground conditions causing hole instability during the transition from mud rotary to diamond drilling, early technical indicators are encouraging. The drilling contractor has taken responsibility for costs of the abandoned hole and remains committed towards a successful outcome for the Centurion Project drilling program, with a second hole already underway on the same pad. While mud-rotary sample contamination and low recoveries limit accurate geological assessment of CN001DD (as expected and inherent to the drilling method), encouragingly, sharply slower mud rotary penetration rates and higher magnetic susceptibility results along with geological observations (Table 2, Figures 2 & 3) indicates the basement interface may lie between 377 and 404 meters depth in this location. Alternative geological interpretations for these effects are plausible, and more definitive evidence from diamond core is still required before the economic potential can be adequately assessed. Nevertheless, the results from CN001DD reinforces Buxton’s confidence in the Centurion Project’s potential to host an Iron Oxide Copper Gold (IOCG) mineral system. As a result of this revised schedule, the basement coring component of the Centurion drilling program is now expected to be completed by mid-August. Buxton remains highly encouraged by the geophysical and geological datasets at Centurion and looks forward to providing further updates as drilling advances. ---o0o--This announcement is authorised by the Board of Buxton Resources Ltd.

The Centurion Project is situated in an excellent regional structural setting, close to a “triple junction” of GSWA’s “Major Crustal Boundaries”. The Project is focussed on a prominent dipolar and offset magnetic and gravity anomaly. This is characteristic geophysical pattern is associated with Iron Oxide Copper Gold (IOCG) deposits such as Olympic Dam, Prominent Hill and Carrapateena. The Centurion magnetic & gravity anomalies extend over 3,500 m by 5,000 m and have amplitudes of ~1,500 nanoTeslas (magnetic) and ~10 milligals (gravity). Analysis of magnetic data indicates that the target is located between 520 - 700 metres beneath ground level under sedimentary rocks of the Canning Basin. A previous drill test was attempted by CRA in 1991 who encountered drilling difficulties and terminated their diamond hole at 432.30 m having failed to reach basement. CRA’s geological logs (WAMEX A35274) noted chlorite-pyrite altered, boulder-sized clasts of felsic and mafic intrusives in a conglomerate assigned to the Permian Grant Formation toward the end of the hole. This observation provides strong encouragement that the geophysical response may be related to a hydrothermal system consistent with the IOCG model, and that the basement interface may not be far below the base of that hole. CRA’s drilling records also indicate that they drilled single shift and converted to diamond at just 198 m depth. Drilling risk can therefore be reduced through continuous drilling operations and using a deeper mud-rotary pre-collar. In November 2023, Buxton entered in Heritage Protection Agreements with the Ngurra Kayanta and Parna Ngururrpa Aboriginal Corporations, and a Heritage Survey was completed in July 2024. Provision for Buxton personnel and contractors to pass through lands of the Kiwirrkurra People is provided by a third access agreement. Buxton has also received permits from the Aboriginal Lands Trust to complete statutory requirements to access the Project. In May 2024, Buxton was awarded a WA Government Exploration Incentive Scheme grant to offset up to $220,000 of the cost of drilling the planned maiden drill hole at Centurion.

These examples should not be taken as limiting the broad meaning of sampling. Buxton’s 2025 drillhole CN001DD was intended to be drilled as a mud-rotary pre-collar through the Canning Basin sediments, with a HQ / NQ diamond coring tail in the ‘basement” rocks that are expected to be Proterozoic rocks that host the dense and magnetic features that are evident in the geophysical response. 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. Drilling techniques PO Box 661 Nedlands WA 6009 In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘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 (eg submarine nodules) may warrant disclosure of detailed information. Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, facesampling bit or other type, whether core is oriented and if so, by what method, etc). 15 Robinson Av Belmont WA 6104 T: 08-9380 6063 CRA 1991 Drilling Program (WAMEX A35274): An 8 inch percussion hole was drilled to 30 metres and cased with 6 inch polypipe. A standard 6-inch percussion hole was drilled from 30 metres to 198 metres. Diamond core (NQ) was drilled from 198 metres to E.O.H. at 432.30m. Buxton 2025 Drilling Program: DD1 Drilling used a Sandvik 1200 DE840 rig supported by a Duplex Power (AXG FX 5” x 6”) mud pump. The mud rotary hole was drilled using 115 mm RC rods (inner tubes removed). A 9” blade bit was used for the top 23 metres, and a 148 E: info@buxtonresources.com.au W: www.buxtonresources.com.au View online https://buxtonresources.com.au/link/PwbbDr Criteria JORC Code explanation Commentary mm PCD mud rotary bit for the remainder of the hole. 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. CRA 1991 Drilling Program (WAMEX A35274): Sampling methods or sample recovery or weights for the percussion precollar are not reported or discussed. CRA’s records do note diamond drilling core recovery for each run, with no significant core loss noted. Buxton 2025 Drilling Program: Mud Rotary Method: Sampling was undertaken using a 10-litre bucket in-line with the borehole fluid return channel between the drillhole and sump. One sample was collected per 6 metre drill rod. Mud Rotary sample recovery and sample quality is considered extremely poor with generally only 0.5-1kg of sample collected which represents <1% recovery, and all samples having apparent contamination from uphole sediments, including a substantial component of fe-ox coated, well rounded (aeolian) sand grains which appear to be derived from the top ~18 metres of the hole. Since the focus was on the pre-Canning Basin “basement” rocks, a high sample quality for the mudrotary section was not an objective of the program. Recoveries are estimated by calculating the drilled borehole volume, converted to weight using a nominal density of 2.6 g/cc and then comparing that value with weight of each sample. These “bulk” samples were initially stored in green biodegradable bags and were then sub-sampled using a 1mm mesh sieved with the coarse fraction stored in chip trays for visual logging an pXRF analysis. No apparent relationship can be defined between sample recovery and grade since no assays have been collected. Logging PO Box 661 Nedlands WA 6009 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. 15 Robinson Av Belmont WA 6104 T: 08-9380 6063 Buxton 2025 Drilling Program: Logging of the mud rotary section was conducted at the Project site by qualified geologists. Onsite logging includes recording observations of lithology, mineralogy and mineralisation, which are recorded digitally. Logging includes the flagging of samples with evidence of contamination.

Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. Sample security Commentary 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. These are first-pass reconnaissance results and the degree to which the sampling may bias the actual grade and extent of mineralisation is highly uncertain. An experienced company geologist was onsite for the sampling. The chain-of-sample custody is managed by BUX staff from collection at the rig to the submission of the samples to a certified laboratory for analysis. Samples are being stored at the drill site before being transported either directly to the laboratory, or to BUX’s secure sample processing and storage facility in Perth. The risk of deliberate or accidental loss or contamination of samples is considered very low, particularly given the remote location of the project.

The Centurion Project is situated at the intersection between Lasseter’s Shear Zone and a deep crustal keel below the Fitzroy Trough which extends along northern margin of Kidson Craton. The Aileron Province lies immediately east of the Project area. The Kidson Craton is an unexposed and unsampled cratonic block that underlies the Canning Basin. The Fitzroy Basement Terrane lies beneath the Fitzroy Trough and is thought to have formed when the Kidson and Kimberley Cratons collided. It is an area of uniquely thick basement which has likely experienced more deformation during Palaeozoic extension than surrounding areas. Significant MVT mineralisation has been localised above the northern FBT margin within the Lennard Shelf. The Lasseter Shear Zone is a significant feature which extends north-south over 1,500 km across the Australian Continent. In the Project area it lies along the eastern edge of the Canning Basin and separates the Kidson Craton from the Aileron Province. It likely initiated during the collision of the Kidson and North Australian Cratons sometime during the MesoProterozoic and has been reactivated during subsequent periods, including the Giles event around 1085–1040 million years ago, as well as the Alice Springs Orogeny in the Late Paleozoic / Early 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/PwbbDr Criteria JORC Code explanation Commentary Mesozoic era. The Centurion Project lies in an area of superb structural preparation, being on the confluence of sutures between crustal elements of diverse history / structural style and a trans-lithospheric scale shear zone. Since very little is known about the basement geology within the Centurion Project, the definition of the target deposit model is almost entirely restricted to the potential field datasets which exhibit an IOCG style geophysical response. The Project is covered by the Cornish Helena 2009 government airborne magnetic (400 m line spacing) and the 2017 Kidson Falcon gravity gradiometer survey (2,500 m line spacing). CRA also undertook some local ground geophysical surveys. The open file airborne gravity and magnetic surveys are of sufficient accuracy and resolution to undertake targeting. It is particularly fortunate that one of the 2.5 km spaced airborne gravity gradiometer flight lines coincides with the centre of the target area and the CRA VE001 drillhole. The principal target is defined by magnetic & gravity anomaly 3,500 m by 5,000 m in extent and 1,500 nT and 10.1 mgal amplitude magnetic / gravity anomaly. The anomalies are coincident at the Project sale, but are slightly offset at the target scale. The size, amplitude and offset pattern is comparable to South Australia’s IOCG deposits such as Olympic Dam (1,000 nT / 20 mgal). Buxton has undertaken inversion and forward modelling of both the airborne magnetic and gravity gradiometery data which places the target at ~ 520 – 700 metres depth.

If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. Magnetic susceptibility data were collected on 6 metre runs. Simple (non-sample weight weighted) averages were used for the calculations presented in Table 2 of the text. Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. Relationship between mineralisation widths and intercept lengths Diagrams PO Box 661 Nedlands WA 6009 The assumptions used for any reporting of metal equivalent values should be clearly stated. These relationships are particularly important in the reporting of Exploration Results. Not applicable – no intersections or assay data are reported. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. 15 Robinson Av Belmont WA 6104 T: 08-9380 6063 See text and figures in body of release.
