Announcement PDF ASX Release ASX:BUX & BUXO 11 August 2025 Centurion Project: Drilling & Next Exploration Steps Buxton Resources Ltd (ASX: BUX & BUXO) is pleased to provide an update on drilling activities at the Company’s 100% owned Centurion Project, where diamond drillhole CN002DD has now been completed. After overcoming initial drilling challenges with CN001DD (see ASX 2/7/2025), Buxton’s second hole was drilled to 808.9 meters before encountering loose sands assigned to a basal unit of the lower Canning Basin cover sequence (Worral Formation, Elsa Sandstone, Figure 3). As there was no viable method on hand to safely manage this drilling risk, and the hole had not reached the basement within the expected depth range (520–700 meters), Buxton elected to complete the hole. Field measurements on drilling samples indicate that some of the cover sequences have slightly elevated density (Table 2). However, due to the lack of basement core and uncertainty around the depth of the basement, the drilling program did not definitively explain the targeted gravity anomaly, which was the primary focus for Iron-Oxide Copper Gold (IOCG) style mineralisation. Magnetic susceptibility measurements of mud rotary samples and diamond core (Figure 1) indicate that the Centurion magnetic anomaly also remains unexplained. This remains a key target for the next round of drilling, as it indicates prospectivity for high-value mineral systems like Cannington (Ag-Pb) & Havieron (Au-Cu), as well as IOCG deposits. The 2025 drilling program was supported by a $220,000 EIS co-funding grant. Buxton has also secured an additional $55,892 in government co-funding to undertake Magnetotelluric (MT) surveys at Centurion. The MT survey is intended to improve the depth-to-basement interpretation and to reveal basement electrical structure. It is believed that the depth to the basement could vary considerably across the tenement area, as indicated by revised magnetic and gravity inversion modelling that suggests significant basement relief (Figure 4). The MT results, along with further analysis of the 2025 drilling results, will directly guide our next exploration phase at Centurion. Buxton's CEO, Marty Moloney, commented: "While Buxton has concluded the Centurion 2025 drilling activities and has commenced de-mobilizing from site, Centurion remains a high-priority target in the project portfolio, and Buxton will keep the market updated with future developments.

The Elsa Sandstone of Worral Group has a maximum thickness of 50 metres and may rest directly on basement in this area. About the Centurion Project The Centurion Project consists of a single EL covering ~80 km2 located in the Great Sandy Desert between Kiwirrkurra and Balgo (Figure 1). 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. Encouragingly, close to the end of hole CN002DD at 799.5 metres depth, an angular pebble conglomerate bed was intersected with polymictic clasts that include hematitequartz and vein quartz alteration and felsic intrusive lithologies (Figure 3). An unexpectedly thick sedimentary sequence above this unit included dense dolomitic lithologies between 540 – 799 metres downhole. These will potentially be responsible for a component of the gravity anomaly. The stratigraphic position of these sediments is tentatively assigned to the Silurian Worral Formation. Prior interpretation of geophysical data indicated the basement was to be intersected at 520 - 700 metres beneath ground level under sedimentary rocks of the Canning Basin. However, the latest drilling information from CN002DD indicates that the Falcon gravity GDD (vertical gradient) anomaly vertically below the drill pad may be related to the development of the dolomitic sediments around a basement high centred on the magnetic and conformed GD anomaly. 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 1 Haring, MO & Allison, ER, 1985, EP-308 Canning Basin : Geological and Geophysical Status Report.

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 drilled as a mudrotary pre-collar through the Canning Basin sediments. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. This hole was intended to have a HQ / NQ diamond coring tail, however instability at the collar arising from insufficient surface casing caused this hole to be abandoned during the mud rotary section at 404 metres depth. Buxton’s 2025 drillhole CN002DD was drilled from the same pad as CN001DD, also vertical, with a mud rotary pre-collar successfully completed to 558.5 metres, and extended to 808.9 metres depth with HQ diamond coring. 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. Mud rotary hole was drilled using 115 mm RC rods (inner tubes removed). A 9” blade bit was used for the top 18-23 metres, and a E: info@buxtonresources.com.au W: www.buxtonresources.com.au View online: https://buxtonresources.com.au/link/4PKJ9r Criteria JORC Code explanation Commentary 148 mm PCD mud rotary bit for the remainder of the Mud Rotary precollar hole. HQ diamond core drilling was used for the lower section of CN002DD. 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 up-hole 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. Mud rotary sampe 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 (unsieved) using a spoon into chip trays for visual logging, pXRF analysis and future reference. Core sample recovery was recorded on a per-run basis onsite during mark-up by qualified geologists, typically within 24 hours of the core having been drilled, allowing for quality checks on drillers’ core block marking. Core recovery for CN002DD is 98.3%. No apparent relationship can be defined between sample recovery and grade since no assays have been collected.

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 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/4PKJ9r Criteria JORC Code explanation Commentary 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 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 for
