Announcement PDF Level 8, 216 St Georges Terrace, Perth, Western Australia 6000 T: +61 (08) 9481 0389 E: info@exultantmining.com.au ACN 684 147 484 21 October 2026 www.exultantmining.com.au SOIL SURVEY EXTENDS UNDRILLED WATSONS COPPER–ZINC CORRIDOR TO 3KM HIGHLIGHTS • Additional pXRF soil sampling extends the Watsons copper–zinc anomalous corridor from approximately 2.4km to 3km, an increase of approximately 25% • Execution of a land access agreement over the adjoining southern property enabled ~600m of additional strike extent to be delineated • The interpreted southern limit of the soil anomaly has now been defined within the surveyed area; the corridor remains open to the north. • Copper–zinc soil responses show a spatial association with magnetic features represented by existing TMI inversion model shells • Watsons has never been drill tested; next steps include extending the survey northeast and assessment of targeted geophysics Exultant Mining Limited (ASX: 10X) (“Exultant” or “the Company”) is pleased to report further results from its portable X-ray fluorescence (“pXRF”) soil sampling program at the Watsons prospect, within the Company’s 100%-owned Black Hammer Project in the Macquarie Arc, New South Wales. Following execution of a land access agreement over the property immediately south of the previously reported survey area, the Company completed an additional 99 pXRF soil measurements. The new results extend the interpreted north-northeast trending copper–zinc anomalous corridor from approximately 2.4km to 3km. The additional sampling has delineated the interpreted southern limit of the soil anomaly within the surveyed area. The corridor remains open to the north. Comment from Executive Chairman, Brett Grosvenor: "Black Hammer has been our priority project from the outset, and Watsons is showing why. Our last update identified a 2.4-kilometre copper-zinc corridor. With access to the southern property secured, we've now extended it by around 25% to approximately three kilometres, and it remains open to the northeast, where we also identified a lead-copper-zinc anomaly. Watsons remains undrilled. In two phases of low-cost soil work, we've taken a 1970s anomaly and built it into a three-kilometre target that lines up with magnetic features. Our next steps are to extend the survey north and assess the geophysics best suited to advancing Watsons toward drilling.” Level 8, 216 St Georges Terrace, Perth, Western Australia 6000 T: +61 (08) 9481 0389 E: info@exultantmining.com.au ACN 684 147 484 www.exultantmining.com.au Cautionary statement—pXRF results All new copper, lead and zinc soil results reported in this announcement were obtained using portable X- ray fluorescence (pXRF) and have not been verified by laboratory assays. The readings are preliminary field measurements used to assess soil geochemical anomalism and should not be regarded as a substitute for laboratory analysis. Subsequent laboratory results may differ from the reported pXRF readings. Soil anomalism does not establish the grade, thickness, continuity or economic significance of underlying bedrock mineralisation. Figure 1.

The work followed execution of a land access agreement over the property south of the existing Watsons survey area. This provided access to test the southern continuation of the approximately 2.4km copper–zinc anomalous corridor reported in the Company’s announcement dated 13 October 2026¹. The new results extend the interpreted corridor approximately 600m southwards, increasing its overall strike extent to approximately 3km. Together with the previously reported 190 measurements, the Watsons program now comprises 289 measurement locations. The additional coverage has delineated the interpreted southern limit of the soil anomaly within the surveyed area. This interpretation relates to the surface geochemical expression; the extent of any underlying bedrock mineralisation remains untested. The approximately 3km corridor describes the overall interpreted strike extent of soil anomalism. Previously reported gaps in sampling coverage through the central swampy drainages remain relevant to interpretation of the combined dataset. These unsampled areas do not establish either anomalous or background concentrations, and continuity through those areas remains unconfirmed. The additional 99 measurements returned peak pXRF readings of 173ppm Cu and 255ppm Zn, both recorded at measurement location WS198. Individual results and coordinates for the 99 additional measurement locations are presented in Table 1. Sampling methodology and QA/QC information are provided in Appendix 1 — JORC Code Table 1.

Red box delineates the newly sampled area GEOLOGICAL SETTING The geological setting at Watsons remains consistent with that described in the Company’s announcement dated 13 October 20261 . The prospect comprises predominantly andesitic volcanic and volcaniclastic rocks of the Ordovician Rockley Volcanics, together with local quartz–feldspar porphyry bodies. In the southern portion of the newly extended sampling grid, this sequence is locally covered by younger Miocene Oberon Basalt. Copper and zinc pXRF readings were generally subdued over areas of outcropping basalt. Elevated readings were, however, recorded at locations within the mapped basalt extent where basalt outcrop was not observed. These observations provide additional information for interpreting the local basalt margin and suggest that the extent and continuity of cover warrant further assessment at the scale of the sampling grid. The soil results alone do not establish the presence or thickness of basalt beneath individual measurement locations. The copper–zinc soil responses also show a spatial association with magnetic features represented by existing total magnetic intensity (“TMI”) inversion model shells, particularly in the northern and Level 8, 216 St Georges Terrace, Perth, Western Australia 6000 T: +61 (08) 9481 0389 E: info@exultantmining.com.au ACN 684 147 484 www.exultantmining.com.au southern parts of the corridor (Fig. 3). This relationship provides a focus for integrating the geological and geochemical information and evaluating complementary ground magnetic and induced polarisation surveys. The magnetic shells represent a selected visualisation threshold within an existing inversion model. Magnetic inversion is non-unique, and the spatial association does not establish the source of the magnetic response or confirm sulphide mineralisation. Figure 3.

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. • Direct in-ground portable X-ray fluorescence (pXRF) measurements were undertaken at Watsons to assess the spatial distribution of historical Cu–Zn–Pb soil anomalism and infill the historical sampling coverage. Approximately 15 cm deep holes were excavated using an Estwing hammer, targeting the B soil horizon. Measurements were taken directly on exposed soil within the holes. Locations with excessive soil moisture, particularly within swampy drainages, were omitted. The additional survey comprised 99 measurement locations, bringing the combined Watsons program to 289 locations. Readings were taken from the base of each hole with one reading per sample location. • Platina Developments initially identified Watsons through regional stream sediment sampling in 1971. Stream sediment samples were sieved to −80 mesh and analysed for Cu, Pb, Zn, Co and Ni. Subsequent soil sampling by Platina Developments (Mines Search) used the −80 mesh fraction, with Cu, Pb and Zn analysed by atomic absorption spectrometry (AAS). ASARCO subsequently undertook additional soil sampling, reporting Cu, Pb and Zn. The soil horizon, collection depth and sample mass used in the historical soil programs are not known from the available information. Where historical sampling, preparation or analytical details are not recorded in the source reports available to Exultant, this limitation is acknowledged and the data are used for early-stage target generation only. Level 8, 216 St Georges Terrace, Perth, Western Australia 6000 T: +61 (08) 9481 0389 E: info@exultantmining.com.au ACN 684 147 484 www.exultantmining.com.au Criteria JORC Code Explanation Commentary 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). • No drilling has been completed by Exultant at the Black Hammer Project and no new drilling results are reported in this announcement. • The Watsons, Porters Retreat and Vermithor priority targets have not been drill tested. • Historical drilling elsewhere within the broader Black Hammer tenure includes shallow aircore drilling within EL9332, historical diamond drilling at the Tuglow Copper Mines within EL9826, and 50 RAB holes for 374m and two RC holes for 77m at the Swatchfield Prospect within EL9913. • The historical drilling elsewhere within the project does not directly test the three priority targets described in this announcement and is included only as project context. 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. • No drill results are reported in this announcement and drill sample recovery is therefore not material to understanding the Watsons, Porters Retreat or Vermithor exploration results. • Recovery information for historical drilling elsewhere within the broader project is variably documented and has not been relied upon to define or rank the three priority targets. 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. • No new drill core or drill chips are reported in this announcement. Historical drill logging elsewhere within Black Hammer is not material to the definition of the Watsons, Porters Retreat or Vermithor targets. Subsampling 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. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Measurements were taken directly on in-ground soil without sieving or laboratory preparation. Consequently, the readings relate to the soil exposed at each measurement location rather than a sieved or homogenised sample. Locations with excessive moisture were omitted.

Whether sieving was undertaken wet or dry, and any subsequent drying, splitting or pulverising procedures, are not known. The sieve fraction and preparation procedures used for the Asarco soil samples were not reported in the historical reports. Quality of assay data and laboratory tests • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • 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. • Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. • Measurements were made using an Evident Vanta Core pXRF instrument, model V2CA-CCC. Three beams were used, each operating for 20 seconds on Geochem mode, giving a total analysis time of 60 seconds per measurement. The instrument is running the latest software V4. 14. 125 and was recently serviced on 27/08/2026. A pure silica blank and certified reference materials OREAS623 and OREAS24b were measured each day before field measurements commenced. These measurements were instrument performance checks. The new soil readings have not been verified by laboratory assays and are reported as preliminary field measurements. The values for Cu, Pb & Zn for the blank and CRM’s were within +/- error limits for the elements reported in this report and no corrective actions were required. Historical Watsons analytical methods, detection limits and QAQC procedures were not fully documented in available historical records. The historical soil results are therefore being used for early-stage target generation. • The initial Platina soil samples were analysed for Cu, Pb and Zn by AAS. The digestion method, laboratory, detection limits and QA/QC procedures are not known from the available information. The analytical method used for the stream sediment samples has not been established. For the ASARCO soil samples, Cu, Pb and Zn results were reported, but the analytical method, digestion, laboratory and QA/QC Level 8, 216 St Georges Terrace, Perth, Western Australia 6000 T: +61 (08) 9481 0389 E: info@exultantmining.com.au ACN 684 147 484 www.exultantmining.com.au Criteria JORC Code Explanation Commentary procedures have not been established. Whether the historical analytical methods represented partial or total extraction is therefore unknown. • The airborne magnetic data used to interpret the magnetic anomalies at Watsons were sourced from Geoterrex in 1991 and acquired at approximately 250m line spacing and a nominal terrain clearance of 80m. • The magnetic data were reprocessed by Montana GIS using a 3D inversion model for VRMI and TMI • The TMI magnetic shells shown in Figure 3 are a selected visualisation threshold from the inversion model. Magnetic inversion is non-unique, and the model does not determine rock type, sulphide content, metal grade or economic significance. Verification of sampling and assaying • The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data • The survey reproduces the broad spatial pattern of historical anomalism. This is a comparison of spatial patterns rather than quantitative verification of historical assay values, because the sampling and analytical methods differ. Laboratory verification of the new pXRF readings has not been undertaken. Each pXRF measurement was assigned a sample ID in the instrument. A GPS waypoint using the same ID was recorded when the reading was taken, linking each measurement to its recorded location. Instrument results were exported to a USB memory stick at the end of each sampling day. Significant readings were not repeated and no corrections, averaging or other adjustments were applied to the reported values. • Historical geochemical and geophysical data were compiled from original or scanned source reports, plans, tables and available digital datasets. Key sample locations, assay values and geological observations used in the figures were checked Level 8, 216 St Georges Terrace, Perth, Western Australia 6000 T: +61 (08) 9481 0389 E: info@exultantmining.com.au ACN 684 147 484 www.exultantmining.com.au Criteria JORC Code Explanation Commentary against the source records where practicable. • Exultant field observations were reviewed internally by the Competent Person. • Magnetic processing and inversion outputs were reviewed by Montana GIS • No historical assay values were adjusted • No twin drilling is relevant because no drill results are reported for the three priority targets. Location of data points • Accuracy and quality of surveys used to locate drill holes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control. • Survey accuracy and quality for historic drill hole locations not documented. • Topographic control adequacy not assessed. • Collar survey methods not consistently recorded. • Historic collars and other geochemical data located using GDA2020/MGA
