Note Intercepts are stated as downhole intervals, and due to the vertical nature of the ore body and restricted collar locations are commonly, but not consistently, at a low angle to the mineralisation 3 Refer to ASX Announcement 1 August 2024 “Group Mineral Resource Statement – Amended” ASX: MRT Page | 2 Managing Director and CEO Mr Grant Haywood commented: “Following strong results previously reported, the latest assays from Burbanks continues to demonstrate consistent high-grade mineralisation and improved geological confidence. The ongoing success of the drilling program continues to de-risk the project, as we progress Burbanks towards becoming a reliable source of feed for Maritana’s 100% owned Black Swan Processing Hub.” Phase 1 Drilling Results Maritana has successfully completed Phase 1 resource definition drilling at Burbanks, with assays results received for all but the final four holes. Drilling focused on Burbanks North, targeting infill within the current Mineral Resource and extensional mineralisation, as well as testing down-dip continuity of shallow mineralisation in the southern area, refer Figure 1. Phase 1 of the drilling program comprised 53 holes, for a total of 15,798m. Figure 1 – Burbanks Mining Centre showing the location of the completed holes in the current drill program and representative long and cross sections Page | 3 Drilling at Burbanks North continues to demonstrate exceptional high-grade gold mineralisation associated with the Burbanks shear (refer Figure 2), which highlights visible gold hosted within quartz veining in the shear zone intersected in hole 26HBBD044. A sectional view of this hole is presented in Figure 3. Assay results for all but three holes in the south, and one to the east have been received. Highlights are shown on the cover page with full results presented in Table 1. Intercepts are stated as downhole intervals and due to the vertical nature of the ore body and restricted collar locations, are commonly, but not consistently, at a low angle to the mineralisation. Drill collar coordinate details for the program drilled to date are shown in Table 2. Figure 2 – Gold mineralisation located within a quartz vein hole 26HBBD044. The interval grades 4.20m @ 42.43g/t Au from 289.63m including 1.37m @ 126.93 g/t Au from 290.84m (refer Table 1). Core width is NQ2 and ≈ 50.5mm in diameter for scale These outcomes enhance the geological confidence of the continuity and extensions of the mineralised system and are being incorporated into the updated geological model and Mineral Resource Estimate currently underway for Burbanks North. A long section (refer Figure 4) highlights pierce points from significant intercepts from both within and outside the current Inferred Mineral Resource envelope, supporting continuity of mineralisation and potential resource extensions.

All assay results from the Burbanks North drilling have been received, enabling the completion of an updated Mineral Resource Estimate in the June 2026 quarter. Ore Reserve studies based on the improved confidence in resource classification from Inferred to Indicated from the updated Mineral Resource Estimate will then follow. Overview – Burbanks A two-phase extensional and infill drilling program commenced at Maritana’s 100% owned, high-grade, Burbanks gold project in late June 2025, with a revised total of 25,000m of reverse circulation (“RC”) and diamond drillholes planned based on results received in the first phase of drilling. Burbanks is located 9km south of Coolgardie in the world-renowned Western Australian Goldfields (Figure 5). Figure 5 – Maritana Minerals project locations, regional geology and surrounding infrastructure Page | 7 Table 1 – Significant intervals for holes 25HBBD0022-036, previously unreported. Assay results for significant intervals from holes 25HBBD022–24 and 25HBBD027 were previously reported December 20254 . Intercepts are down hole and not true width and were calculated based on a sample returning an assay value of greater than 1.0g/t Au over an interval no less than 0.2m and no greater than 1.2m, with no more than 1m of internal dilution. Intervals are based on geology and no top cut off was applied. No significant result is represented as NSI in the table. All other assays from the reported drill holes were below the defined cut-off grade of 1.0 g/t Au and are not considered material for public reporting Hole ID From To Intercept Width Au g/t 26HBBD037 99.00 100.00 1.00 4.91 26HBBD037 102.80 103.20 0.40 2.19 26HBBD037 142.45 143.15 0.70 1.55 26HBBD037 146.00 146.50 0.50 2.40 26HBBD037 167.00 168.00 1.00 1.24 26HBBD037 203.00 203.40 0.40 1.15 26HBBD037 212.64 213.00 0.36 3.49 26HBBD037 263.70 264.24 0.54 1.78 26HBBD038 78.00 79.00 1.00 5.84 26HBBD038 406.50 407.00 0.50 2.75 26HBBD038 426.00 426.47 0.47 3.29 26HBBD038 445.49 446.00 0.51 1.51 26HBBD038 458.90 459.23 0.33 1.02 26HBBD038 460.37 461.00 0.63 24.32 including 460.37 460.67 0.30 40.95 26HBBD038 479.74 480.04 0.30 1.35 26HBBD038 489.50 490.00 0.50 1.05 26HBBD039 67.12 67.67 0.55 6.36 26HBBD039 81.35 81.65 0.30 2.28 26HBBD039 90.57 91.02 0.45 3.28 26HBBD039 222.63 223.15 0.52 2.42 26HBBD039 253.30 254.07 0.77 2.60 26HBBD039 257.66 257.99 0.33 1.51 26HBBD039 354.51 361.00 6.49 2.66 including 355.97 357.24 1.27 6.54 and 360.00 360.47 0.47 5.68 26HBBD039 362.53 363.55 1.02 1.18 26HBBD040 113.88 115.69 1.81 13.82 26HBBD040 129.12 129.48 0.36 1.07 26HBBD040 134.77 135.11 0.34 1.48 26HBBD040 137.00 137.40 0.40 3.39 26HBBD040 159.79 160.11 0.32 2.22 4 Refer ASX Announcement on 17 December “Ultra High-Grades Returned in Burbanks Phase 1 Drilling” Page | 8 Hole ID From To Intercept Width Au g/t 26HBBD040 165.00 167.06 2.06 2.26 26HBBD040 296.00 297.42 1.42 2.23 26HBBD040 330.71 331.06 0.35 1.23 26HBBD041 NSI 26HBBD042 38.00 38.60 0.60 1.30 26HBBD042 210.30 211.60 1.30 1.68 26HBBD042 217.00 218.00 1.00 1.47 26HBBD042 220.95 222.82 1.87 2.83 26HBBD042 226.00 226.50 0.50 1.57 26HBBD042 229.04 229.70 0.66 1.32 26HBBD042 244.98 247.00 2.02 5.99 including 244.98 245.35 0.37 9.05 26HBBD042 277.30 277.85 0.55 1.23 26HBBD042 369.00 371.00 2.00 1.47 26HBBD043 162.22 163.00 0.78 1.51 26HBBD043 178.38 178.73 0.35 1.30 26HBBD044 207.41 207.71 0.30 54.02 26HBBD044 218.75 219.20 0.45 2.60 26HBBD044 223.00 224.84 1.84 5.98 including 223.64 224.84 1.20 8.69 26HBBD044 289.63 293.83 4.20 42.43 including 290.84 292.21 1.37 126.93 26HBBD044 295.64 296.25 0.61 1.87 26HBBD044 303.00 304.00 1.00 1.19 26HBBD044 323.00 324.00 1.00 1.17 26HBBD044 330.00 332.00 2.00 1.39 26HBBD044 335.00 339.00 4.00 1.09 26HBBD044 345.00 345.88 0.88 1.12 26HBBD045 105.09 106.30 1.21 1.92 26HBBD045 172.00 173.00 1.00 1.67 26HBBD047 102.81 103.54 0.73 4.62 26HBBD047 117.72 119.21 1.49 1.49 26HBBD047 261.00 261.30 0.30 1.06 26HBBD047 263.9 264.5 0.6 1.41 26HBBD048 NSI 26HBBD049 76.96 77.26 0.30 2.75 26HBBD049 117.00 118.00 1.00 1.45 26HBBD049 122.50 123.70 1.20 1.37 Page | 9 Hole ID From To Intercept Width Au g/t 26HBBD049 225.70 226.70 1.00 1.42 26HBBD049 229.62 230.14 0.52 10.83 26HBBD050 178.00 179.00 1.00 1.04 26HBBD050 204.20 204.61 0.41 3.12 Table 2 - Collar location details of Phase 1 diamond holes at Burbanks, in GDA2020, Zone 51 and local mine grid Hole Id MGA94 East MGA94 North Local East Local Noth RL Dip Azi EOH (m) Results 26HBBD037 323677 6568097 1706 7893 400.0 -60 130 350.00 received 26HBBD038 323393 6568050 1525 7670 415.9 -61 130 504.60 received 26HBBD039 323357 6567659 1757 7353 393.3 -77 132 420.53 received 26HBBD040 323277 6567148 2037 6919 380.3 -61 309 363.50 received 26HBBD041 323040 6566703 2156 6428 387.0 -55 310 95.60 received 26HBBD042 323040 6566703 2156 6428 387.0 -64 311 402.52 received 26HBBD043 323040 6566703 2156 6428 387.0 -57 308 352.40 received 26HBBD044 323043 6567160 1854 6772 387.5 -79 132 420.10 received 26HBBD045 323804 6568127 1780 8000 395.2 -68 129 290.54 received 26HBBD047 323829 6568217 1740 8084 397.3 -70 130 350.00 received 26HBBD048 324018 6568416 1748 8359 399.6 -65 130 290.10 received 26HBBD049 321422 6565149 1978 4192 401.2 -60 310 224.00 received 26HBBD050 321285 6565064 1932 4038 405.9 -59 310 220.00 received 26HBBD051 321192 6565028 1887 3948 407.9 -60 210 159.40 received 26HBBD052 322964 6566678 2115 6359 389.3 -68 130 235.00 pending 26HBBD053 321547 6565349 1938 4424 400 -60 310 153.50 pending Page | 10 Table 3 - Maritana Minerals Limited – Burbanks Gold Mineral Resources Project Cut-off Measured Indicated Inferred Total Au g/t Mt Au g/t Ounces Mt Au g/t Ounces Mt Au g/t Ounces Mt Au g/t Ounces Burbanks OP 0.5 1.43 2.02 92,800 3.43 1.86 204,900 4.86 1.90 297,700 Burbanks UG 2.5/2.0 0.12 4.26 16,700 1.07 4.39 151,200 1.19 4.38 167,900 Total 1.55 2.19 109,500 4.50 2.46 356,100 6.05 2.39 465,600 *Appropriate rounding applied.

Forward looking statements include, but are not limited to, statements preceded by words such as “planned”, “expected”, “projected”, “estimated”, “may”, “scheduled”, “intends”, “anticipates”, “believes”, “potential”, “could”, “nominal”, “conceptual” and similar expressions. Forward looking statements, opinions and estimates included in this announcement are based on assumptions and contingencies which are subject to change without notice, as are statements about market and industry trends, which are based on interpretations of current market conditions. Forward looking statements are provided as a general guide only and should not be relied on as a guarantee of future performance. Forward looking statements may be affected by a range of variables that could cause actual results to differ from estimated results and may cause the Company’s actual performance and financial results in future periods to materially differ from any projections of future performance or results expressed or implied by such forward looking statements. These risks and uncertainties include but are not limited to liabilities inherent in mine development and production, geological, mining and processing technical problems, the inability to obtain any additional mine licenses, permits and other regulatory approvals required in connection with mining and third party processing operations, competition for among other things, capital, acquisition of reserves, undeveloped lands and skilled personnel, incorrect assessments of the value of acquisitions, changes in commodity prices and exchange rate, currency and interest fluctuations, various events which could disrupt operations and/or the transportation of mineral products, including labour stoppages and severe weather conditions, the demand for and availability of transportation services, the ability to secure adequate financing and management’s ability to anticipate and manage the foregoing factors and risks. There can be no assurance that forward looking statements will prove to be correct. Statements regarding plans with respect to the Company’s mineral properties may contain forward looking statements in relation to future matters that can only be made where the Company has a reasonable basis for making those statements. This announcement has been prepared in compliance with the JORC Code (2012) and the current ASX Listing Rules. The Company believes that it has a reasonable basis for making the forward-looking statements in the announcement, including with respect to any production targets and financial estimates, based on the information contained in this and previous ASX announcements. Cautionary statement Statements in this report relating to the LOM of mine pertain to the Company’s Scoping Studies which were originally released to the ASX on 17 February 2026 and are preliminary in nature. The Scoping Studies include Indicated and Inferred Mineral Resources and are based on low-level technical and economic assessments, which are insufficient to support estimation of Ore Reserves. There is no certainty that the study outcomes, including production targets and financial assumptions, will be realised.All material assumptions and technical parameters underpinning the Scoping Study production targets and financial information continue to apply and have not materially changed since that announcement. Page | 12 Appendix 1 – JORC Table 1 Burbanks Project – 2025 JORC Code (2012) Table 1, Sections 1 and 2 The following Table and Sections are provided to ensure compliance with the JORC Code (2012 edition) guidelines for the reporting of Mineral Resources. SECTION 1 Sampling Techniques and Data Burbanks Project (Criteria in this section apply to all succeeding sections) Criteria JORC Code explanation Commentary Sampling techniques Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. Sampling was conducted using multipurpose Reverse Circulation (RC) and Diamond Core (DD) drilling rig from surface. For RC drilling, samples were collected as both 4m composites and 1m splits using a cyclone and cone splitter to obtain a ~2-3kg representative samples. Diamond drilling was used to obtain ½ NQ2 core samples of various lengths (minimum 0.2m and maximum 1.2m), from which 1-3kg of material is collected for assaying. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. RC samples were collected directly from a cyclone and cone splitter mounted on the rig to give 4m composites and a 1m split. The cyclone and splitter were cleaned regularly to minimize contamination. Page | 13 SECTION 1 Sampling Techniques and Data Burbanks Project (Criteria in this section apply to all succeeding sections) Criteria JORC Code explanation Commentary For DD drilling, samples were collected as half-core (NQ2) using geological intervals and mineralisation boundaries which is considered appropriate for this style of mineralisation. 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. Field duplicates, QAQC certified reference standards and blanks were collected/inserted at a rate of 1 in every 20m (maximum) through pre-determined mineralised zones. All samples were crushed and split to produce a 500g jar for Photon assay. Sampling and QAQC procedures are carried out using Maritana protocols consistent with industry best practice. 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). RC drilling was carried out using a face sampling hammer with a 127mm (5”) drill bit. DD was NQ2 through the main zones of mineralisation. Core was oriented every 6m where possible using an electronic orientation tool. Page | 14 SECTION 1 Sampling Techniques and Data Burbanks Project (Criteria in this section apply to all succeeding sections) Criteria JORC Code explanation Commentary Drill sample recovery Method of recording and assessing core and chip sample recoveries and results assessed. Sample recoveries for RC are visually estimated qualitatively on a metre basis and recorded in the database. Measures taken to maximise sample recovery and ensure representative nature of the samples. Drilling contractors adjust their drilling approach to specific conditions to maximise sample recovery. RC samples were visually assessed for recovery and moisture. A cyclone and cone splitter were used to provide uniform sample. 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 sample recovery issues have impacted on potential sample bias. 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. All drilled intervals (RC and DD) are logged and recorded. Data for DD core was recorded for regolith, lithology, veining, fabric (structure), grain size, colour, sulphide presence, alteration, oxidation state, fractures, and RQD. Maritana considers the data to be of an appropriate level of detail to support future resource estimations. Page | 15 SECTION 1 Sampling Techniques and Data Burbanks Project (Criteria in this section apply to all succeeding sections) Criteria JORC Code explanation Commentary Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. Logging is both qualitative and quantitative in nature depending on the field being logged. Logging of RC chips and DD core was qualitative, both were photographed. RC chips trays and DD core is stored at the Company’s core yard on-site at Burbanks. The total length and percentage of the relevant intersections logged. All drillholes are logged in full. Sub-sampling techniques and sample preparation If core, whether cut or sawn and whether quarter, half or all core taken. DD core is cut in half next to the orientation line. The right-side of the core is collected for analysis and the left side retained for reference. Duplicate samples were submitted at a rate of 1:20m through mineralised zones and certified reference standards were inserted at a rate of 1:20m (maximum) through mineralised zones based on geological interpretation. Samples were sent to Intertek Laboratories, where they were dried and crushed to 2 mm before a 500 g split was taken for photon assay. If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. All RC samples were passed through cyclone and cone splitter, and a 2-3kg split sample is collected for each 1m interval and similarly a 4m interval.

All other zones within the RC were sampled by collecting a 4m composite sample. For all sample types, the nature, quality and appropriateness of the sample preparation technique. The sample type and size is considered appropriate for this type and style of mineralisation Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. Laboratory QA/QC controls during the analysis process include duplicates for reproducibility, blank samples for contamination and standards for bias. The laboratories used have generally demonstrated analytical accuracy at an acceptable level within 95% confidence limits. Laboratories also employ their own internal QA/QC protocols. 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. Laboratory duplicates were generated from the coarse crushed material as part of the analytical process to monitor sample precision. For diamond core, the core was orientated and consistently cut next to the orientation line, with the right-hand side of the core submitted for assay. This procedure ensures that sampling is systematic and representative of the in-situ material.

The sample size is considered appropriate for this type and style of mineralisation 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. RC and DD samples were sent to Intertek Laboratories for analysis by Photon Assay. A 500 g sample is assayed for gold by Photon Assay (method PAAU02, upper limit 350ppm) along with quality control samples including certified reference material, blanks and duplicates. Photon method PAAU02H (upper limit 3500ppm Au) and PAAU02HH (absolute Au) where used for samples of very high grade. SG measurements are routinely collected using the water displacement method at an average rate of 1 every 20m and include each lithological unit. 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. No geophysical tools or XRF instruments have been used at Burbanks. Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. Laboratory QA/QC controls during the analysis process include duplicates for reproducibility, blank samples for contamination and standards for bias. The laboratories used have generally demonstrated analytical accuracy at an acceptable level within 95% confidence limits.

All drilling and significant intersections are verified and signed off by the Chief Geologist for Maritana Minerals who is also a Competent Person. The use of twinned holes. No pre-determined twin holes were drilled during this program. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Geological logging was originally captured on formatted excel templates, then sent to the company’s inhouse database manager utilising Geobank v2025.1 software for uploading into the company database via a validation process. Laboratory assay and downhole survey data is captured electronically. Uploaded data is reviewed and verified by the geologist responsible for the data collection. Discuss any adjustment to assay data. No adjustments or calibrations were made to the assay data reported.

Drill hole collar locations are positioned with a hand-held GPS. Systematically through-out, and on completion of the program and any Mineral Resource estimation the collar locations will be surveyed by a qualified surveyor using sophisticated DGPS with a nominal accuracy of +/- 0.05m for north,
