Announcement PDF ASX Announcement 25 August 2026 ASX: OD6 1 HORSESHOE CHANNEL RE-ASSAYS CONFIRM MATERIALLY HIGHER GRADE FLUORSPAR FROM SURFACE Re-assays supersede and materially increase Horseshoe channel results reported on 8 July 2026 Highlights • ALS Global laboratories informed OD6 that the original assay technique used for the Horseshoe channel samples can exhibit a negative bias for this specific high-grade fluorspar matrix, resulting in under- estimation of fluorine and calculated CaF₂ grades • Re-assaying by ALS confirms a material uplift in CaF₂ grades compared with the original. • Horseshoe Channel Sampling results originally reported on 8 July 2026, are now re-reported herein • Standout results of re-assayed results, from expanded in-pit channel sampling: o SE Wall: 50m @ 79.3% CaF2 (previously reported as 63.9%) o North Pit: 27m @ 65.1% CaF2 (previously reported as 54.4%) o NW Wall combined 22m @ 78.8% CaF2 (previously reported as 70.7%) including: ▪ 9m @ 84.5% CaF2 (previously reported as 74.4%) ▪ 8m @ 80.0% CaF2 (previously reported as 71.2%) ▪ 5m @ 66.7% CaF2 (previously reported as 62.4%) o Central Bench: 15m @ 85.8% CaF2 (previously reported as 65.8%) • 31 samples at Horseshoe return >90% with peak value of 98.8% CaF2 • An average increase of 12.9% CaF2 using the updated ALS assay method • New assay results align with the recent large-format metallurgical samples returning 90% and 76.2% CaF2 (refer release dated 12 August 2026) • Channel Sampling within mapped 80m wide exposed zone, with previous reported drilling and open pit exposure indicating a tabular zone 15 to 30m thick • Mineralisation remains open up-dip beneath the silicified cap and down-dip beneath talus cover, highlighting significant expansion potential • Outstanding consistency demonstrated across all 120 channel samples averaging 74.8% CaF2, with 85% of samples grading above 50% CaF2 at an average of 90.4% CaF2.. Managing Director Brett Hazelden, commented: “Establishing the appropriate assay technique for the ultra high grade fluorspar mineralisation being encountered has been essential. ALS advised that the original method can under-estimate fluorine for this specific high-grade matrix, and the re-assays now confirm that the previously reported Horseshoe grades were materially under-called - an average uplift of 12.9%. Grades approaching 80% CaF₂, over significant widths, are exceptional in a global fluorspar context, particularly when they occur from surface within a broad replacement-style mineralised system. Importantly, Horseshoe is not presenting as a conventional narrow-vein fluorspar deposit. The mineralisation is exposed across an approximately 2 80-metre-wide zone, with previous drilling and pit exposure indicating a tabular body approximately 15 to 30 metres thick that remains open. For investors, the significance is the combination of grade, width and scale. These latest results, together with the exceptional grades being returned from our metallurgical samples, continue to strengthen our view that Horseshoe has the potential to become a significant high-grade fluorspar deposit. We are now focused on demonstrating the scale of the system through drilling and advancing the metallurgical and ore-sorting programs to determine the most efficient pathway to Metspar and premium Acidspar products. Acidspar prices in the US reached approximately US$654/t in July 2026¹, highlighting the potential value of producing a premium-grade fluorspar product into a strategically important and import-dependent US market.” ¹ Source: ChemAnalyst, Fluorspar Price Trend and Forecast, data accessed 5 August 2026.

Coordinates NAD83 Zone 11 3 OD6 Metals Limited (ASX: OD6, “OD6” or “the Company”) is pleased to announce the re-assay results from expanded channel sampling completed at the Horseshoe Prospect, part of the Company’s exciting Quinn Fluorspar Project in Nevada, USA Re-assay program and why At the commencement of work on this project the Company approached ALS Global Ltd to establish appropriate assay techniques. ALS Global is the world’s largest mineral exploration testing company, is renowned for precision and reliability and has been the preferred laboratory for OD6 Metals since the company’s inception. The preferred technique for fluorine analysis is ME-XRF24 (F-XRF24) and is the technique used by Tivan Ltd for its Speewah Project in Western Australia. This is a highly reliable technique using an initial oxidation to remove volatiles (H2O and CO2) and then a fusion at 1100o C to dissolve sample metal into a glass bead before high-powered X-Ray Fluorescence performed under laboratory conditions. F-XRF24 is not available via ALS Global laboratories in North America, and as such an alternate assay method was proposed, F-ELE82, which uses a fusion by sodium hydroxide and a leach of citric acid, before analysing the F through analysis of the selective ion electrode. OD6 Metals Competent Person, Darren Holden, contacted ALS with queries when a sample containing apparent high-grade fluorspar returned assay results less than expected. ALS conducted some investigations into the F- ELE82 technique. ALS advised that due to matrix limitations with these specific high-grade samples, the F-ELE82 method exhibits a negative bias, meaning the true fluorine concentrations in previously reported high grades were possibly underestimated (this was noted in the original release JORC table by the Company on 8 July 2026) The Company requested ALS to send residual pulps of all samples that reported >50,000ppm fluorine (~10% fluorspar) to Perth, Western Australia for re-assay with the F-XRF24 technique as a comparison. Following the recent metallurgical assay results from Core Metallurgy, which also used F-XRF24, returned higher than expected grades, the Company accelerated the re-assay program with the results presented herein. The re-assayed results set out in this announcement supersede the corresponding channel sampling results reported on 8 July 2026 and therefore the superseded assay results should no longer be relied upon. Figure 2 presents a comparison of results in the two techniques, noting how the largest variation is in the higher-grade results. Figure 2 Re-assay program with F-XRF24 versus the original F-ELE82 4 Following advice from ALS that the F-ELE82 method is semi-quantitative for this specific high-grade fluorspar matrix, the Company has elected to utilize F-XRF24 for all samples going forward. Channel Sampling Channel sampling is a systematic method in which samples are collected using a hammer drilling and the excavated material is collected as a series of contiguous samples over set intervals. Because each sample represents a fixed width, the technique delivers a representative measure of grade across the sampled interval, and — where the channel is oriented as close as practicable to perpendicular to the strike of mineralisation. It is a well-established approach for characterising exposed mineralisation in pit walls, trenches and outcrop. Collapse areas of pit wall, with no observed or safely reachable exposed rock were not sampled. Significance of these results These results are an outstanding outcome for the Horseshoe deposit, confirming broad zones of exceptionally high-grade fluorspar at surface. Standout channel intervals of 22m at 78.8% CaF2 in the north-west wall, 15m at 85.8% CaF2 on the central bench, 50m at 79.3% CaF2 in the south-east/back wall and 27m at 65.1% CaF2 in the north pit — including individual samples grading up to 98.8% CaF2 — demonstrate both the very high tenor and the impressive width and continuity of mineralisation across the historic pit. Grades of this magnitude sit well above the 40% CaF2 threshold that defines high-grade fluorspar and confirm the potential for Horseshoe to deliver premium, high-value product. Critically, these results reinforce Horseshoe as a genuinely significant, near-surface, high-grade fluorspar opportunity in Nevada — one of the world's premier mining jurisdictions. With the United States currently 100% reliant on imported fluorspar and the mineral firmly established on the US Critical Minerals list, the scale and quality of mineralisation emerging at Horseshoe position the Quinn Fluorspar Project to play a meaningful role in securing domestic supply. The Company is highly encouraged by these results and views Horseshoe as developing into an outstanding opportunity, with clear momentum to advance the project through the next phases of work. Initial development concepts will evaluate a staged approach targeting early Metspar production opportunities, with subsequent beneficiation studies assessing the potential production of higher-value Acidspar products. Quinns Fluorspar Project U.S Strategic Advantage The Quinn Fluorspar Project, located in Nevada, USA, provides OD6 with direct exposure to a strategically important critical mineral within the United States. The Project's key attributes include: • location in Nevada, USA, one of the world’s established mining jurisdictions • a historical fluorspar mining district containing multiple known fluorspar occurrences • OD6 has now consolidated 100% ownership of 226 mining claims covering ~1,890 hectares • +20 Fluorspar occurrences, supporting a future hub-and-spoke development strategy • exceptionally high-grade fluorspar mineralisation demonstrated through OD6’s recent exploration and sampling programs • Multiple high-priority drill targets defined from integrated geological mapping, fluorine geochemistry, structural interpretation and historical drilling • 8km fertile mineralised corridor confirmed with additional high-grade fluorine anomalies identified outside known deposits • Low impurity mineralisation supports potential production of premium Acidspar (>97% CaF₂) and Metspar products following beneficiation 5 • Permitting program underway, including environmental baseline, archaeological studies and preparation of drilling and bulk sample approvals • Metallurgical testwork advancing with optical sorting and beneficiation studies to optimise premium product recoveries • Potential Gold Upside identified in soil sampling across Mammoth, Horseshoe and Dress Circle Together, these results reinforce OD6's view that Quinn has the potential to emerge as a strategically significant domestic source of high-grade fluorspar in a U.S. market that remains 100% net import reliant.

above and/or below in the pit wall, and excluded from the intercept calculations as they do not represent the continuity of the mineralization. JORC 2012 – Table 1: Quinn Fluorspar Project Section 1 Sampling Techniques and Data (Criteria listed in the preceding section also apply to this section) Criteria JORC Code explanation Commentary Sampling techniques • Nature and quality of sampling (eg 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. • 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 • Channel samples are chip-channels, where a line is marked out and a representative sample is collected with a hammer drill from 1m intervals along the side of historic pit. Drilling techniques • 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, face- sampling bit or other type, whether core is oriented and if so, by what method, etc). • No drilling reported 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 • No drill sampling reported 13 Criteria JORC Code explanation Commentary recovery and grade and wheth
