Announcement PDF ASX Announcement 8 July 2026 ASX: OD6 1 SPECTACULAR GRADE & WIDTHS CONTINUES AT HORSESHOE 50M @ 63.9% CaF2 AT SURFACE Results confirm a substantially larger, high-grade fluorspar system Highlights • Exceptional high-grade channel sampling results confirm broad zones of continuous high-grade fluorspar mineralisation from surface at Horseshoe • Results demonstrate exceptional scale and continuity of the mineralised system, supporting potential for a large, near-surface high-grade fluorspar deposit • Standout results, including the thickest mineralised interval to date, from expanded in-pit channel sampling: o SE Wall: 50m @ 63.9% CaF2 o North Pit: 27m @ 54.4% CaF2 o NW Wall combined 22m @ 70.7% CaF2 including: ▪ 9m @ 74.9% CaF2 ▪ 8m @ 71.2% CaF2 ▪ 5m @ 62.4% CaF2 o Central Bench: 15m @ 75.8% CaF2 • Channel Sampling confirms mineralised widths of 60m 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 118 channel samples averaging 64.4% CaF2, with 84% of samples grading above 50% CaF2 at an average of 70.7% CaF2 Managing Director Brett Hazelden, commented: "These channel sampling results represent another outstanding outcome for OD6 and further validate the scale, exceptional grade, width and geological potential of the Horseshoe deposit within the Quinn Fluorspar Project. Standout results including 22m @ 70.7% CaF2 in the NW Wall, and 50m @ 63.9% CaF2 in the SE Wall demonstrate both the scale and consistency of high-grade fluorspar mineralisation across significant widths from surface. Remarkably, the average of all 118 channel samples returned 64% CaF2, with over 80% of channels grading above 50% CaF2 at an average of 70.7% CaF2. Horseshoe is NOT a typical narrow vein Nevada fluorspar vein, but a large high-grade replacement zone lending itself to modern open pit mining techniques. The combination of near-surface mineralisation, exceptional grades and significant widths provides OD6 with the opportunity to evaluate potential early-stage development pathways, including the production of Metspar products, while advancing metallurgical programs targeting premium Acidspar specifications. 2 This staged development approach has the potential to provide a lower complexity pathway into production, leveraging the naturally high-grade nature of the Horseshoe mineralisation and growing demand for secure domestic fluorspar supply in the United States. With mineralisation remaining open both up-dip and down-dip, we believe Horseshoe continues to develop into a strategically important fluorspar opportunity at a time when the United States remains fully reliant on imported supply of this critical mineral.” Figure 1 Horseshoe channel sample results on background geology, (geology modified after Evans, 1975) 3 OD6 Metals Limited (ASX: OD6, “OD6” or “the Company”) is pleased to announce the assay results from expanded channel sampling completed at the Horseshoe Prospect, part of the Company’s exciting Quinn Fluorspar Project in Nevada, USA About Quinn Fluorspar Project On 9 June 2026 the Company announced the exercise of the option agreement to acquire the Quinn Fluorspar Project (which remains subject to shareholder approval at the General Meeting on 20 July 2026), located approximately 220km north of Las Vegas, Nevada. The project offers very high-grade fluorspar mineralisation (>40% CaF2) identified at the Mammoth and Horseshoe Projects in replacement / breccia style mineralisation mapped out over large 9,000m2 and 3,000m2 areas respectively. In addition, a number of other fluorspar occurrences are noted in the wider project area with reported historic rock chip results up to 98.6% CaF2 (refer announcement 12 May 2026). Preliminary work by the Company has revealed Mammoth, Horseshoe and Big Jim to be very high grade and potentially significant deposits of fluorspar (refer presentation 20 May 2026 for summary and therein, a list of material announcements). The United States is currently 100% reliant on imports of fluorspar highlighting the strategic importance of domestic supply. Fluorspar is listed on the US Critical Minerals list with applications in battery technologies, AI chip manufacture, nuclear fuels industry, aerospace and defence technologies. The project is located ~300km by road from the US Strategic Minerals Reserve at Hawthorne, Nevada (refer to previous Company announcements) 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 70.7% CaF2 in the north-west wall, 15m at 75.8% CaF2 on the central bench, 50m at 63.9% CaF2 in the south-east/back wall and 27m at 54.4% CaF2 in the north pit — including individual samples grading up to 74.9% 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. 4 Figure 2 Prospect map: with fluorine pathfinder indicators in soils over regional geological mapping (refer release 1 July 2026 for details). 5 Regional Setting, mineralization styles The Quinn Fluorspar deposits are part of the Great Basin (Basin and Range) of Nevada. The deposits are hosted in Paleozoic sediments including the Pogonip Limestone Formation and the Simonson Dolomite. Mesozoic to Cenozoic (Tertiary) intrusions and volcanism resulted in a significant epithermal event through the district. Fluorspar (CaF₂) is deposited in epithermal breccias, veins and as replacement deposits parallel to the bedding in the limestone.

wall, and excluded from the intercept calculations as they do not represent the continuity of the mineralization. 11 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 ofsampling (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 shouldnotbe takenas limitingthe broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibrationofany measurement tools or systems used. • Aspects ofthe determination ofmineralisation that are Material to the Public Report. • In cases where ‘industrystandard’ work has been done this would be relatively simple (eg ‘reverse circulationdrilling was used to obtain 1 m samples from which 3 kgwas pulverised toproduce a 30 g charge for fire assay’). In other cases more explanationmay 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 alongthe 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- samplingbitor other type, whether core is oriented and if so, by what method, etc). • No drilling reported Drill sample recovery • Method ofrecordingand 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 andwhether sample bias may have occurred due to preferential loss/gain of fine/coarse material. • No drill sampling reported Logging • Whether core and chip samples have been geologically andgeotechnically logged toa 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. • Geology recordedwith each sample, as noted in Table 1 in the body of the release. Sub-sampling techniques and sample preparation • Ifcore, whether cut or sawn and whether quarter, half or all core taken. • Ifnon-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. • Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. • 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. • Whether sample sizes are appropriate to the grain size of the material being sampled. • No sub-sampling reported 12 Criteria JORC Code explanation Commentary 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 geophysicaltools,spectrometers,handheldXRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature ofqualitycontrol procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels ofaccuracy (ie lack of bias) and precision have been established. • Samples were delivered toALS Global in Reno, NV for preparation. • Samples were dispatched, by the laboratory, for assay by ALS Global inVancouverusing F-ELE82technique for fluorine content. • The laboratory adhered tointernal QA/QC techniques with no discrepancies noted. • Samples were consistentingrade with internal visual estimates of observed mineral content and historic work, and are hence considered reasonable in the context with which they appear. • All fluorine is assumed toreportto CaF2.CaF2is 48.7% F. Results factor this stochiometriccalculation based on F results from the laboratory. • ALS has reported that some highgrades maybe under- callingdue toCa complexing with F to form CaF+ ion. Further investigations underway. 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. • Samples are consistent with historic sampling as reported by the Company 4 March 2026 Location of data points • Accuracy and quality ofsurveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used inMineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control. • Data points located in NAD83 Zone 11andusing hand- held GPS with assumedaccuracy of+-5m. Start ofeach channel is recorded,andpositioned along the pit wall. Data spacing and distribution • Data spacing forreportingofExploration Results. • Whether the data spacing and distribution is sufficient to establish the degree ofgeological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. • Sampling confirms continuity of mineralization. In absence of drilling, does not provide sufficient information for mineral resource estimation. Orientation of data in relation to geological structure • Whether the orientation of sampling achieves unbiased samplingofpossible structures and the extent to which this is known, considering the deposit type. • Ifthe relationshipbetween the drilling orientation and the orientation ofkey mineralised structures is considered tohave introduced asamplingbias, this should be assessed and reported if material. • Orientation ofchannel sampling is along historic pit walls and exposed areas. They do not represent true width (refer to Figures in the body of
