Buxton Resources Ltd (ASX: BUX) is pleased to report the successful finalisation and de-risking of three high-priority drill targets at the 100%-owned Lateron Project, targeting intrusive-related Cu/Au mineralisation (see Figures 1 & 2 for detailed cross section and maps). The Lateron Project is located at the western margin of the Tanami Province, 150km south from Halls Creek (see Figure 5 for location map). The new targets result from 3D geophysical inversion modelling of new, detailed ground gravity and high resolution open-file magnetics and are constrained by reconnaissance passive seismic surveying. The modelling has identified four discrete, highly magnetic features arranged around a central high-density, structurally controlled block. Drilling is planned to test several of these features in 2026. Crucially, petrographic results (Figures 3 & 4) from historic drill core fragments confirm the presence of magmatic amphibole and titanite alongside pyrite and chalcopyrite. These minerals are highly encouraging as they are derived from magmas with high water content & sulphur solubility – these are commonly associated with magmatic/hydrothermal copper-gold deposits. The Company is presently finalising the negotiation of a Heritage Protection / Land Access Agreement with the Tjurabalan Native Title Lands Aboriginal Corporation. Once finalised, Buxton can then seek to undertake heritage surveys to allow for the commencement of a drilling program in 2026.

Several discrete, highly magnetic zones (purple) are interpreted to represent similar magnetite- and sulfide-bearing felsic rocks as were intersected by historic drillhole S-19 and which are prospective for intrusion-related copper-gold mineralisation. A deeper gravity high (dark blue line) suggests the presence of mafic magmatic rocks which are potentially also related to the S-19 intrusives. Petrographic results from fragments of core recovered from the site of S-19 confirm the presence of magmatic amphibole and titanite, in addition to pyrite and chalcopyrite. These minerals provide strong encouragement for exploration at Lateron: they indicate the diorite is derived from hydrated magmas with high sulphur solubility. Such rocks tend to be related-to, and occur nearby magmatic / hydrothermal sulphide deposits. The passive seismic results, together with records from historical drilling, indicate that the light blue gravity isoshell (the lowest gravity contrast mapped by Buxton’s inversion processing) is mimicking the base of Paleozoic cover sequence. Spatial variations mapped by this surface indicate a strong local structural control - these structures are apparently reactivated during the deposition of the cover sequence. Such long-lived structures also provide strong support for the Project’s mineral-deposit prospectivity. Three drillholes are planned to test these magnetic features for copper-gold mineralisation.

The chips are classified as “hornblende quartz diorite” and varies to tonalite where quartz content exceeds 20%. Medium grained textures with the dominant assumed plagioclase completely replaced by sericite. The feldspar is commonly associated with allotriomorphic sub-0.5mm quartz. The ferromagnesian silicates are predominantly green pleochroic hornblende. Brown pleochroic biotite is subordinate and can be chloritized. There are clusters of subhedral 0.5mm epidotes, and quite coarse titanite. The ore content, probably about 5%, consists of oxides and sulphides. Oxides are dominantly magnetite as rather angular crystals to 0.2mm, often showing partial oxidation to hematite. The sulphides are predominantly fresh pyrite which has a range of grain sizes, and subhedral habit to 0.5mm. Chalcopyrite is present as rare fines.

Historic uranium exploration by AFMECO in the early 1980s included a core hole which targeted one of these magnetic features. Logs from that hole record the presence of sulphide bearing mafic / ultramafic intrusions for which assays were not reported at the time, and which have never been followed-up. Airborne magnetic surveys indicate that this suite of mafic-ultramafic intrusive rocks is remnantly magnetised and underly an area of ~ 7 km2 . Buxton is targeting magmatic-hydrothermal base & precious metal mineralisation associated with these sulphide bearing intrusions.

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 (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. The ground-based gravity survey was carried out by Atlas Geophysics Pty Ltd using a 200m by 200m spaced grid pattern, expanded to 400m by 400m around the perimeter. The gravity survey was completed in 5 days of acquisition. An average acquisition rate of around 103 stations per day of production was achieved for the survey. The sampling techniques used are deemed appropriate for the style of exploration. Gravity Data points were collected using: - One CG-6 Autograv Gravity Meter (Serial Number: 21050345, SF: 1.000240) - One CHCi70+ GNSS Rover Receiver - One CHCi70+ GNSS Base Receiver - An autonomous GPS with a 2m accuracy was used to locate the survey locations. - The gravity meters used for the survey had been recently calibrated on the Guildford Cemetery – Helena Valley Primary School calibration range (2010990117 - 2010990217) in Western Australia. - The calibration process validated each gravity meter’s scale factor to ensure reduction of the survey data produces correct Observed Gravities from measured dial reading values. - One new GNSS/gravity control station, 202509100001 “Myarra Pool” was used to control all field observations throughout the project. - GNSS control was established at 202509100001 by, submitting three 10-hour sessions of static data to Geoscience Australia’s AUSPOS processing system, where possible, producing first-order geodetic coordinates. These coordinates are accurate to better than 10mm for the x, y, and z observables. - The acquired GNSS raw data were processed daily using Novatel Waypoint GrafNav v9.00 post-processing software. - Gravity control was established at station 202509100001 via ties to existing gravity stations in the P201161 “Kimberly Road Traverses” survey. Standard deviation of the ties is 0.014mGal. - Each loop contained a minimum of two 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/yEMEoy Criteria JORC Code explanation Commentary repeated readings so that an interlocking network of closed loops was formed. - A total of 15 repeat readings representing 2.91% of the survey were acquired for quality control purposes. Repeat readings were evenly distributed, where possible, on a time-basis throughout each of the gravity loops. - Repeatability of the data was excellent, with the standard deviation of the elevation repeats at 0.013m and the standard deviation of the gravity repeats at 0.007mGal. - Post processing and interpretation was completed by Buxton. mHVSR “passive seismic” readings were collected using three Tromino three component 5Hz seismometers. Additionally, three SmartSolo IGU16- HR three component 5Hz seismometers were deployed for quality assurance testing at three of the 6 sites.

Buxton is presently negotiating a Land Access Agreement (LAA) with CCNTS to facilitate on ground exploration activities. The Lateron Project overlaps with the Paruku Indigenous Protected Area (IPA) in the far western part of the EL. There is no express framework for managing the Paruku IPA in relation to exploration activities - it is not a reserve for the purposes of Part III of the Aboriginal Affairs Planning Authority Act 1972 (WA) requiring a mining permit/ministerial consent and is not a reserve under the Land Administration Act 1997 (WA) requiring Ministerial consent to explore.

Exploration done by other parties Acknowledgment and appraisal of exploration by other parties. Historic exploration by AFMECO in 1982 targeted roll front uranium mineralization in Paleozoic sediments. One of their diamond drill holes intersected shallow “basement” rocks at 77.5 m vertical depth in hole S-19. The drill logs for this hole indicate the basement lithology consists of “basic, foliated, coarse grained pyroxenite containing abundant pyrite, hematitic quartz veins and dolerite differentiations”. AFMECO reported no geochemical assay results for any of their drill holes which were instead systematically logged by a geophysical tool sensitive only to uranium mineralisation.

Buxton identified the AFMECO’s 1982 diamond drillhole S19 drill site during field reconnaissance and found that a substantial amount of discarded core remained. Most of this material was clearly siliciclastic and likely belonged to the Knobby Sandstone (Devonian cover sequence). However, several fragments of intrusive textured diamond drill core totalling 75 grams were recovered. Petrological analysis on these fragments has described the lithology as “biotite hornblende quartz diorite” which has been altered “with coarse titanite and sericite / muscovite pyrite-magnetite- chalcopyrite overprint”. This lithological and alteration association is highly encouraging for magmatic-hydrothermal Cu-Au mineralisation. Geology Deposit type, geological setting and style of mineralisation. The Lateron Project lies at the far northeastern edge of the Canning Basin where GSWA mapping indicates that the Billiluna Shelf drapes over the Paleoproterozoic sequences of the Birrindudu Basin (1640-1725 Ma) and Tanami Basin (1864 – 1844 Ma). The Billiluna Shelf dips gently towards the southwest where it terminates against the Balgo Terrace. The Halls Creek Mobile Zone forms the main structural feature north of the Billiluna Shelf. The Lateron Project is completely covered by unconsolidated surficial deposits including alluvium, windblown sand of 1-20 metres thickness, with variable development of underlying Cenozoic Kaolinitic and sandy clays associated with calcrete and silcrete which reach 30 metres thickenss. This cover sequence overlies the Upper Devonian Knobby Sandstone of the Billiluna Shelf, which consists of fluvial fossiliferous medium to coarse grained cross-bedded quartz sandstone with abundant mudstone pellets in places; minor interbedded siltstone and pebble to boulder conglomerate (Hocking et al, 2008). The Birrindudu Group also consists of siliciclastic sediments, and the sequences of the Tanami Basin and Tanami Orogen including metasedimentary siliciclastic: psammite and pelite; interlayered and intruded by with meta-igneous mafic and felsic intrusives.
