Announcement PDF 1 ASX:RTR Western Queen MRE Optimised for Underground Mining Study ASX RELEASE I 28 OCTOBER 2026 Rumble Resources Limited / ASX:RTR ABN 74 148 214 260 www.rumbleresources.com.au Head Office Level 1, 52 Kings Park Road West Perth, WA 6005 Contact Us T. +61 8 6555 3980 E. info@rumbleresources.com.au Key Highlights • Substantial Grade Uplift - Overall resource grade increased by 19% to 3.1 grams per tonne gold compared to the June 2026 Mineral Resource Estimate, reflecting the tighter geological wireframing tailored to selective underground extraction • Enhanced Resource Profile - Total Mineral Resource now stands at 3.92 Mt @ 3.1 g/t Au for 393,100 ounces of gold. • Quality Upgrade - Indicated Resources at Western Queen South delivered a 27% increase in grade with a negligible 1% reduction in total contained ounces, reinforcing the high-grade continuity of the core mineralisation. Peter Harold, Managing Director and CEO commented: “This optimised Western Queen Mineral Resources Estimate represents a significant step in our assessment of the potential to transition Western Queen into an operating mine. By applying tighter wireframing controls, we have delivered a significantly higher grade resource model. While total contained ounces saw a minor reduction from the June 2026 Resource Estimate, the 19% increase in overall grade and in particular the 27% grade uplift in the Indicated resource category at Western Queen South has provided a far more robust foundation for stope design which has been applied to the mining schedule in the updated Western Queen Scoping Study.” Rumble Resources Limited (ASX: RTR) (“Rumble” or the “Company”) is pleased to announce an optimised Mineral Resource Estimate (“MRE”) for the Western Queen Gold and Tungsten Project (“Western Queen” or the “Project”). Following recent detailed underground mining engineering studies, the MRE has been re-estimated with tightly constrained lode wireframes. This refined interpretation aligns directly with planned underground stope optimisation parameters, improving spatial confidence and grade selectivity for mine planning. Western Queen Gold Underground Resource Optimisation Following detailed mine design work on the June 2026 Resource of 5.13Mt @ 2.6g/t Au for 433,600 oz1 Rumble has reinterpreted the geological domains using tighter wireframed grade constraints specifically tailored to better fit the underground mine design. Lode wireframes were produced using at 1.0g/t cut-off grade to remove the low-grade peripheral mineralisation adjacent to the higher-grade target zones, whilst block sizes within the model were also adjusted from 5m x 1m x 1m to 5m x 1m x 5m to better reflect the mineralisation orientation at Western Queen. 1Refer to Rumble ASX release 24 June 2026 “Western Queen Gold Resources Upgraded to 433kozs” 2 ASX:RTR Rumble Resources Limited / ASX:RTR ABN 74 148 214 260 www.rumbleresources.com.au Head Office Level 1, 52 Kings Park Road West Perth, WA 6005 Contact Us T. +61 8 6555 3980 E. info@rumbleresources.com.au No additional drilling data was incorporated in this resource estimate. The revised Mineral Resource Estimate now stands at 3.92Mt @ 3.1g/t Au for a total of 393,100 oz of contained gold. This represents a 19% increase in total resource grade to 3.1g/t Au, for only 9% reduction in total ounces compared to the June 2026 resource. Most importantly, Indicated resources at Western Queen South and Central increased 27% in grade with a negligible 1% reduction of ounces, significantly improving the quality and confidence of the targeted underground mining blocks Compared to the July 2025 resource2 overall ounces have increased by 6% and maintained the high overall grade, whilst Indicated ounces have increased by 51%, which significantly derisks the project with more ounces now converted into the higher confidence resource category. The revised MRE includes Indicated and Inferred Resource classifications in accordance with the Australasian Code of Reporting of Identified Mineral Resources and Ore Reserves (JORC Code 2012), with all the resources located within granted Mining Leases, M59/208 and M59/45. Refer to Table 1 for a breakdown of Indicated and Inferred Resources by deposit area at Western Queen.

This drilling program was primarily designed to convert and upgrade Inferred Resources to the higher confidence Indicated category at both Western Queen South and Western Queen Central4, while deeper drilling successfully targeted high-grade down plunge extensions of the main mineralised zones5. This conversion and targeting strategy delivered excellent results - refer to Figure 2 for updated resource locations. 4 Refer to Rumble ASX release 14 January 2026 “Multiple high-grade gold intercepts at Western Queen including 30.72g/t Au over 5.8 metres” 5 Refer to Rumble ASX release 12 February 2026 “High-grade gold intercept extends Western Queen South mineralisation to over 500m down plunge” 4 ASX:RTR Rumble Resources Limited / ASX:RTR ABN 74 148 214 260 www.rumbleresources.com.au Head Office Level 1, 52 Kings Park Road West Perth, WA 6005 Contact Us T. +61 8 6555 3980 E. info@rumbleresources.com.au Figure 2 - Longitudinal section of Western Queen Resources, previous mining and exploration potential High-Grade Zone at Western Queen Central The drill program completed in April 2026 together with geological interpretation and modelling defined a significant high-grade zone at Western Queen Central (“WQC”). This high-grade zone measures approximately 250m x 100m and contains 129kt at 11.6 g/t Au for 48,500 oz of gold in this revised resource, almost entirely in the Indicated resource category (refer to Figure 3). This high-grade zone is located immediately down-plunge from the existing WQC open pit and historical underground workings, representing a high-priority target for future development. Previous historical models assumed that substantial portions of this high-grade area were intruded and diluted by barren pegmatites, but diamond drilling from the most recent drill campaign and updated structural modelling have successfully demonstrated that these pegmatites "stope out" (displace) far less of the high-grade gold mineralisation than previously modelled. 5 ASX:RTR Rumble Resources Limited / ASX:RTR ABN 74 148 214 260 www.rumbleresources.com.au Head Office Level 1, 52 Kings Park Road West Perth, WA 6005 Contact Us T. +61 8 6555 3980 E. info@rumbleresources.com.au Figure 3 –High-grade gold zone below the Western Queen Central pit and underground workings 6 ASX:RTR Rumble Resources Limited / ASX:RTR ABN 74 148 214 260 www.rumbleresources.com.au Head Office Level 1, 52 Kings Park Road West Perth, WA 6005 Contact Us T. +61 8 6555 3980 E. info@rumbleresources.com.au Western Queen Mineral Resources Summary The updated MRE was independently prepared by Ashmore Advisory Pty Limited (“Ashmore”) in accordance with the Australasian Code of Reporting of Identified Mineral Resources and Ore Reserves (JORC Code 2012). • Estimation Technique: Grade estimation was completed utilising Ordinary Kriging (OK), strictly constrained within interpreted geological and mineralization domain wireframes. • Mining Depletion: The resource model has been fully depleted for all historical open-pit and underground mining voids to ensure accurate reporting of remaining in-situ mineralisation. • Depth-Constrained Cut-off Grades: To demonstrate reasonable prospects for eventual economic extraction, the Western Queen Resource is reported using a dual cut-off grade approach based on depth: o Open Pit Potential (Above 245mRL): Reported at a 0.5 g/t Au cut-off. o Underground Potential (Below 245mRL): Reported at a 1.5 g/t Au cut-off. • Rationale for 245mRL Boundary: The 245mRL level represents the base of the historical Western Queen Central Open Pit. Note - Historically Western Queen Central has a production profile of 660kt at 8.9 g/t Au for 190,000 oz. The Western Queen deposits are characterised as structurally controlled, shear-hosted gold mineralisation focused along the prominent Western Queen Shear Zone (“WQSZ”). The WQSZ strikes northeast-southwest (NE-SW) and dips steeply at approximately 70° to the west. Structural geological logging from the comprehensive 2024–2026 drilling programs has confirmed that high-grade gold mineralisation is driven by a shallow to moderate (30°–40°) south-dipping plunge. This structural control strongly aligns with the observed overall grade distribution within both the Western Queen South (“WQS”) and Western Queen Central (“WQC”) ore bodies. The updated MRE was constrained by explicit mineralisation domains constructed in Leapfrog software. Wireframes were generated using interval selection interpretations for mineralized zones exceeding a nominal 1.0g/t Au threshold, applying the following strict technical criteria: • Grade Threshold: Minimum composite gold grade interval of >1.5 g/t Au. • Internal Dilution: A maximum of 2m of contiguous internal waste was permitted within any single intercept. • Extrapolation: Zones were extended up and down-dip either halfway to the nearest unmineralised drill hole in well-drilled areas, or up to a maximum distance of 60m in more sparsely drilled portions of the deposit.

In addition, there are four exploration tenements (E20/0967, E59/2816, E59/3021, and ELA59/3130) over the area, covering the northern and southern strike extent of the mineralised Western Queen Shear Zone (WQSZ) in the Warda Warra greenstone belt. Geology and Geological Interpretation The Western Queen tenements lie within the Archaean Warda Warra Greenstone Belt, a north trending enclave within the Murchison Province of the Yilgarn Craton. The Western Queen and Western Queen South deposits are within the Kylie Mining Group and are the largest known deposits within the Warda Warra Greenstone Belt. The Warda Warra Greenstone Belt is approximately 35km in length, and at the southern end near the Western Queen deposit it is 2km wide, while at the northern end it is up to 7km wide. The north striking and steeply west dipping Warda Warra Greenstone Belt is a layered sequence that has been metamorphosed to amphibolite grade and is enveloped by recrystallised granitoids. At Western Queen, the geology is steep westerly dipping and comprises intercalated sheared amphibolites of mafic to ultramafic composition with thin iron formation horizons, komatiitic basalt, dolerite sills, and talc chlorite schists. Later dolerite and pegmatitic felsic intrusives cut across the amphibolites and gold mineralisation. Mineralisation is associated with sheared silica-sulphide zones with an ultramafic footwall and a mafic hanging wall. The mineralised zone is strongly recrystallised and massive, comprising phlogopite-chlorite-tremolite-talc schist, amphibolite with lenticular quartzo-feldspathic layering and quartz-muscovite-biotite-sillimanite schist. Pyrite, pyrrhotite, chalcopyrite, molybdenite and scheelite are present. Depth of complete oxidation is approximately 30m to 60m with depth to fresh rock approximately 45 to 80m. A zone of lacustrine and paleochannel sediments up to 45m thick overlies the WQS deposit. Sampling and Sub-Sampling Techniques Sampling procedures followed by historical operators are assumed to be in line with industry standard practice at the time. Since 2019, RC drilling by RTR was used to obtain 1 m samples with a cone splitter at the rig to produce a 1.5-2.5kg sample. Diamond drilling completed by Rumble was sawn as ½ core (for NQ) and sampled. The samples were transported to the laboratory (ALS Perth) for analysis via 30g or 50g Fire Assay. Previous companies have conducted diamond drilling with mostly ½ core or rarely ¼ core taken. Drilling Techniques The Western Queen deposit has been drilled using Rotary Air Blast (RAB), Air Core (AC), Reverse Circulation (RC) and diamond drilling (DD) techniques over numerous campaigns by several operators. The RC drilling for resource definition and grade control used a nominal 5½ inch diameter face sampling hammer. AC drilling used a conventional 3½ inch face sampling blade to refusal or a 4½ inch face sampling hammer to a nominal depth. The diamond drilling was undertaken as diamond tails to the RC holes, diamond core from surface, or diamond tails to mud rotary pre-collars. In most cases diamond drilling though the mineralised zones used NQ2 sized equipment. RAB and AC drilling has been excluded from the MRE. RC sample recovery was visually assessed and recorded where significantly reduced. Very little sample loss was noted. The diamond drilling recovery was excellent with very little, or no core loss identified. RC samples were visually checked for recovery, moisture and contamination. A cyclone and splitter were used to provide a uniform sample and these were routinely cleaned. DD drilling was undertaken and the core measured and orientated to determine recovery, which was generally 100%. 8 ASX:RTR Rumble Resources Limited / ASX:RTR ABN 74 148 214 260 www.rumbleresources.com.au Head Office Level 1, 52 Kings Park Road West Perth, WA 6005 Contact Us T. +61 8 6555 3980 E. info@rumbleresources.com.au Classification Criteria The Western Queen Mineral Resource was classified as an Indicated and Inferred Mineral Resource based on data quality, sample spacing, and lode continuity. The Indicated Mineral Resource was defined within areas of close spaced RC and DD drilling of predominantly 25m by 20m, and where the continuity and predictability of the lode positions was good. The Inferred Mineral Resource was assigned to areas where drill hole spacing was greater than 25m by 20m or where small, isolated pods of mineralisation occur outside the main mineralised zones, and to geologically complex zones. Sample Analysis Method Historical gold assays were carried out by a combination of aqua regia and fire assay. Rumble has predominantly used ALS Perth for analytical gold determinations through fire assay. The sample was crushed, a 250g split was taken and pulverised. Assaying for gold was via a 30g or 50g charge lead collection fire assay with AAS finish. Estimation Methodology The mineralisation was constrained by wireframes prepared using a 1.0g/t gold cut-off grade, which were generated in Leapfrog software by Rumble. Following a review of the population histograms and log probability plots, it was determined that the application of high-grade cuts was required, with cuts ranging between 10 and 75g/t gold. A total of 54 composites were cut. The block model parent block dimensions used were 5m north-south by 1m east-west by 5m vertical with sub-cells of 0.625m by 0.5m by 0.625m and the model was rotated on a bearing of 020° to match the approximate strike of the mineralisation. The parent block size dimension was selected on the results obtained from Kriging Neighbourhood Analysis, as well as input from the mining engineer to assist with underground optimisation processes. The Mineral Resource block model was created and estimated in Surpac using Ordinary Kriging (“OK”) grade interpolation. An orientated ‘ellipsoid’ search was used to select data and adjusted to account for the variations in lode orientations, however all other parameters were taken from the variography. Up to four passes were used for each domain. First pass had a range of 30m, with a minimum of 6 samples. For the second pass, the range was extended to 60m, with a minimum of 4 samples. For the third pass, the range was extended to 150m, with a minimum of 2 samples. A final pass was used to estimate the remaining unestimated blocks. A maximum of 16 samples was used for all passes, with a maximum of 6 samples per hole. Bulk densities used for the Western Queen Mineral Resource estimate was based on 171 measurements completed by RTR on rock core samples using the water displacement method, as well as known values from historical mining. The following bulk densities as tonnes per cubic metre (t/m3) were used: • Oxide: 1.9 t/m3 • Transition: 2.56 t/m3 • Fresh: 2.87 t/m3 Cut-off Grade The Mineral Resource has been reported at 0.5g/t Au cut-off above the 245mRL for open pit mining and at a 1.5g/t Au cut-off below the 245mRL for underground mining. The 245mRL is the maximum depth of the Western Queen Central mined pit. In addition, pit optimisation work conducted by consultant mining engineers supports this approach. The reporting cut-off parameters were selected based on assumed economic cut-off grades for the Project. 9 ASX:RTR Rumble Resources Limited / ASX:RTR ABN 74 148 214 260 www.rumbleresources.com.au Head Office Level 1, 52 Kings Park Road West Perth, WA 6005 Contact Us T. +61 8 6555 3980 E. info@rumbleresources.com.au Mining and Metallurgical Methods and Parameters The deposits have previously been mined using selective open pit mining methods and small-scale underground development. Metallurgical test work was undertaken by previous operators. Historical production has demonstrated that good gold recovery can be expected from conventional processing methods. The average processing recovery used for the pit optimisations was 93%, which is supported by actual production statistics.

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. • The Western Queen gold deposit has been sampled using Rotary Air Blast (“RAB”), Air Core (“AC”) drilling, Reverse Circulation (“RC”) drilling and Diamond (“DD”) drilling over numerous campaigns by several companies and currently by Rumble Resources Limited (“RTR”). The RAB and AC samples have been excluded from gold interpolation for this Mineral Resource estimate. • Sampling procedures followed by h
