OD6 Metals Limited (OD6 or the Company) is pleased to announce that the CPC Optioneering Study, supported by metallurgical testwork completed by the Australian Nuclear Science and Technology Organisation (ANSTO), has delivered a preferred process flowsheet for the Splinter Rock Rare Earth Project. This innovative flowsheet achieves high recoveries, superior product quality, and improved cost outcomes, positioning Splinter Rock as one of the leading clayhosted rare earth developments in Australia. This work brings a close to the Optioneering Study and enables work to commence on the next phase of advanced Scaleup Metallurgical Testing and Project Studies. What have been the Aims for Flowsheet Development? The Optioneering Study and testwork program has taken the opportunity to not only test a standard flowsheet but to look at enhancements that can make the Splinter Rock Rare Earth project more resilient. As a result of having multiple technically viable flowsheets, OD6, ANSTO and CPC Engineering (CPC) have started with the end product in mind first with the key aims including: • Produce a High Quality Mixed Rare Earth Carbonate (MREC) or Mixed Rare Earth Hydroxide (MREH) • Enable the final product to be sold to multiple different countries and downstream process worldwide • Balance a simple process with the need to produce a quality product • Optimise product payability as a percentage of Rare Earth Oxide (REO) pricing • Review benefits of removing Uranium and Thorium from the final product to enable safe transport • Optimise Overall Recovery from mine through to the final product • Minimise Acid and other reagent consumptions • Lower energy consumption • Optimise capital and operating costs • Optimise Project economics • Allow for Expandability • Consider technical and commercial rick Preferred Process Flowsheet Plus Metallurgical and Study Outcomes to Date OD6, CPC and ANSTO have successfully demonstrated and recommended a multi-stage processing pathway outlined in Figue1 (refer Flowsheet 6 below), that efficiently produces a superior quality product with low impurities, that has achieved high REE element total flowsheet recoveries as detailed in Figure 2. The Preferred Process flowsheet has built on the metallurgical and optioneering study outcomes to date which have been progressively reported to the ASX as per the following: 1. Heap Leaching – Simple, low-acid usage leaching of rare earth-bearing clays to generate enriched leachate solution (refer ASX 16 October 2024) 2. Nanofiltration (NF) – Recycling of Acid, concentration of REEs and reduction of liquid volume produced downstream (refer ASX 4 August 2025) 2 3. Ion Exchange (IX) – Concentration of rare earth elements and enhanced removal of iron (Fe) and aluminium (Al) reducing downstream processing risk (refer ASX 7 August 2025) 4. Impurity Removal (IR) – Final removal of residual deleterious elements (e.g. Al, Ca, Fe, U, Th, P) to meet high product quality and low impurity specifications. 5. Product Precipitation – Recovery of high-grade Mixed Rare Earth Carbonate (MREC) or Mixed Rare Earth Hydroxide (MREH) from purified solution (refer ASX 13 August 2025) 6. Chlor-Alkali Facility (CAF) – Confirmed as a cost-reduction measure, producing key reagents onsite and materially lowering operating costs (refer ASX 2 September 2025) 7. Low Cost Route – The Optioneering Study supports heap leaching as the lower cost and higher recovery option when compared to conventional agitated tank leaching for the Splinter Rock Rare Earth Project at the Inside Centre Deposit (refer ASX 11 September 2025) The final MREC/MREH products contain elevated concentrations of Nd, Pr, Dy and Tb, collectively representing a high-value magnetic rare earth mix highly sought after in permanent magnet supply chains. Benchmark payability for MREC and MREH typically ranges between 70–85% of REO basket value. The Company aims to be a 6,000 plus tonnes per annum (tpa) producer of REO , in either the form of Mixed Rare Earth Carbonate (MREC) or Mixed Rare Earth Hydroxide (MREH) in 5 years (refer ASX 11 September 2025) Figure 1: Preferred Process Flowsheet from ANSTO Testwork and CPC Optioneering Study 3 Inside Centre Deposit Extraction by REE Total REE % Recovery 80 70 60 50 40 30 20 10 0 La Ce Pr Nd Sm Eu Gd Tb Dy Ho Er Tm Yb Lu Y TREY Figure 2: Anticipated Inside Centre Total REE Recovery by Element Utilising the Preferred Process Flow Sheet Flowsheets Tested and Considered OD6 has sequentially tested several flowsheets over time starting with a relatively simple flowsheet that would produce a lower quality product, through to a more complex flowsheet with a higher quality product, higher recovery of REEs plus lower reagent usage requirements. Each flowsheet tested is summarised below with its pros and cons. Flowsheet 1 Simpletest flowsheet where by the ore is heap leached, followed by a standard two stage Impurity Removal (IR) at a pH of ~4.15 and ~5.5, followed by precipitation of a MREC or MREH at a pH ~7.5. Pros and Cons: • Simple process • Overall REE Recovery is lower due to REE losses in the Impurity Removal stage • No acid recovery and recyling • IR circuit required to treat 100% of the volume of heap leach liquor • Average product quality due to higher Al, Fe, U and Th residual impurities 4 Flowsheet 2 Builds on Flowsheet 1 with the introduction of a REE Ion Exchange (IX) module prior to Impurty Removal. The IX concentrates the REEs onto a Resin that is then eluted back into solution prior to the IR circuit (similar to how carbon is utilised in a gold CIP/CIL circuit). The volume of liquor reporting to the IR circuit is signifcantly decreased. IR is a standard two stage impurity removal at a pH of ~4.1 and ~5.5, followed by precipitation of a MREC or MREH at a pH ~7.5. Pros and Cons: • IX Concentrates REEs requireing a smaller IR circuit • Some impurity rejection during IX • IX barren liquid unable to be recycled • Overall REE Recovery is similar to Flowsheet 1 • No acid recovery and recyling • IR circuit treats a reduced volume of heap leach liquor • Average product quality due to higher Al, Fe, U and Th residual impurities Flowsheet 3 Builds on Flowsheet 2 with the introduction of a Nanofiltration (NF) to recover acid from the IX barren liquid. Recovered acid is then recycled to the Heap leach circuit. The IX concentrates the REEs on to a Resin that is then eluted back into solution prior to the IR circuit. IR is a standard two stage impurity removal at a pH of ~4.1 and ~5.5, followed by precipitation of a MREC or MREH at a pH ~7.5. Pros and Cons: • >80% acid recovery in the NF permeate • IX Concentrates REEs requireing a smaller IR circuit • Some impurity rejection during IX reducing RE loss in IR • Overall REE Recovery is improved marginally • IR circuit treats a reduced volume of heap leach liquor • Circuit complexity increasd in number of steps • Extra NF circuit increase Capital Cost but loweres operating cost due to reduced acid requirements • Average product quality due to higher Al, Fe, U and Th residual impurities 5 Flowsheet 4 Builds on Flowsheet 1 with the introduction of a Nanofiltration (NF) to recover acid direct from the Heap Leach and then recycled to the Heap leach circuit. NF reduces liquor volume reporting the the IR circuit signifantly. IR is a standard two stage impurity removal at a pH of ~4.1 and ~5.5, followed by precipitation of a MREC or MREH at a pH ~7.5. Pros and Cons: • >80% acid recovery in the NF permeate • No Impurity rejection during NF • NF Concentrates REEs requireing a smaller IR circuit • Overall REE Recovery is similar to Flowsheet 1 • IR circuit treats a reduced volume of heap leach liquor • Removes cost of IX circuit • Average product quality due to higher Al, Fe, U and Th residual impurities Flowsheet 5 Builds on Flowsheet 4 and Is a reordering of Flowsheet 3. Nanofiltration (NF) recovers and recycles acid to the Heap leach circuit. NF reduces liquor volume reporting to the IX circuit signifantly. The IX concentrates the REEs on to a Resin that is then eluted back into solution prior to the IR circuit. The volume of liquor reporting to the IR circuit is reduced further and impurities also reduced. IR is a standard two stage impurity removal but given the improved feed volume and quality the pH set points can be optimsed to ~3.5 and 4.4, followed by precipitation of a MREC or MREH at a pH ~7.1 to 7.5. Pros and Cons: • >80% acid recovery in the NF permeate • NF reduces liquor volume to IX by ~65% decreasing cuircuit size • IX Concentrates REEs requireing a smaller IR circuit • Cleaner IX eluate allows for simple IR and lower pH, reducing REE loss due to coprecipitation • Overall Recovery REE is improved • IR circuit treats a further reduced volume of heap leach liquor • Circuit complexity increasd in number of steps but total plant size and equipement requirements signifantly decreased • Total Capital Cost lower due to smaler downstream circuit sizes and also lowers operating cost due to reduced acid requirements and plant size • Improved product quality due to better impurity removal of Al and Fe, but not, U and Th 6 Flowsheet 6 Builds on Flowsheet 5. An an additional U/Th Ion Exchange step is added to improved product quality and increase payability. No change to NF, REE IX and IR operating circuits. Pros and Cons: • >80% acid recovery in the NF permeate • NF reduces liquor volume to IX by ~65% decreasing cuircuit size • IX Concentrates REEs requireing a smaller IR circuit • Cleaner IX eluate allows for simple IR and lower pH, reducing RE loss due to coprecipitation • Overall Recovery REE is improved • IR circuit treats a reduced volume of heap leach liquor • Circuit complexity increasd in number of steps but total plant size and equipement requirements signifantly decreased • Total Capital Cost lower due to smaler downstream circuit sizes and also lowers operating cost due to reduced acid requirements and plant size • Improved product quality due to better impurity removal or Al, Fe, U and Th Next Steps Complete Metallurgical Core Program: Drilling due to be completed in October with core samples dispatched to ANSTO also in October. ANSTO Testwork Scale Up: Heap Leach and Impurity Removal testwork as described above • Heap leach Optimisation: Heap Leach duration and kinetics, Acid strength and consumption, Counter current heap configuration, Particle agglomeration methodology • Impurity Removal Verification: Nanofiltration (NF) acid recovery, Ion Exchange (IX) selectivity and elution to reduce Fe/Al and trace U/Th, plus two stage Impurity removal (IR) optimisation • Bulk MREC and MREH Production: Precipitation to produce >1 kg of MREC and/or MREH for customer qualification, offtake discussions, and to assess commercial payability options Mining Study to Commence: Burnt Shirt have been engaged to conduct a mine options study at the Inside Centre Deposit to consider geology, mining method, pit shell analysis, stripping ratios, high level mine scheduling and preliminary mining costs Engagement with potential offtake partners: To assess commercial payability options for MREC and MREH products. Engagement with government and potential financing partners: OD6 has and continues to engage government and potential financing organisations. This is anticipated to be a continuous process over the development cycle. Selective Nd, Pr, Tb and Dy Oxide Production Potential: Whilst initial development at Splinter Rock targets MREC or MREH, the onsite Chlor-Alkaly Facility (CAF) positions OD6 for potential future production of individual oxides (Nd, Pr, Dy, Tb, and potentially Sm, Y) through a chloride-based SX process. Discussions with ANSTO to conduct a desk top assessment are advancing and may be commenced during 2025. 7 Competent Persons Statement The scientific and technical information that relates to process metallurgy is based on information reviewed by Mr Brett Haze lden (Managing Director and CEO) of OD6 Metals Limited.

Rare Earth Elements OD6 Metals has successfully identified clay hosted rare earths at its 100% owned Splinter Rock Project which is located in the Esperance-Goldfields region of Western Australia. The Company released a Mineral Resource Estimate (MRE) for Splinter Rock in May 2024, confirming that the project hosts one of the largest and highest-grade clay-hosted rare earths deposits in Australia with an Indicated Resource of 119Mt @ 1,632ppm TREO and an Inferred Resource of 563Mt @ 1,275ppm TREO with an overall ratio of ~23% high-value Magnetic Rare Earths (MagREE). OD6 Metals believes that Splinter Rock has all the hallmarks of a world class rare earths project with a conceptual heap leach development which utilises the large and high-grade Splinter Rock resource to support a long-life REE operation. Copper The Company is advancing the Gulf Creek Copper-Zinc VMS Project located near the town of Barraba in NSW, Australia. Gulf Creek was mined at around the turn of the 20th century and was once regarded as the highest-grade copper mine (2% to 6.5% Cu) in NSW until its closure due to weak copper prices in 1912. Very little exploration has occurred at the project in over 100 years, with OD6 aiming to apply modern day exploration technologies. The 2025 maiden drilling program successfully defined high grade copper below the historical mine plus confirmed the strong relationship between magnetism and massive sulphide mineralisation. Geophysical modelling has identified multiple, high priority and untested targets ready for drilling providing over >3km of untested strike in the immediate mine-stratigraphy, and over >10km across the tenement.

A total 6 holes were selected (see table below) to composite at Inside Centre with samples combined by weight to reflect the intercept length to maintain representativity and minimise any bias. Column (Heap) Leach tests agglomerated the samples with a small amount of flocculant (~300g/t) to wet the ore and bind the fines together. They are then irrigated with 25 g/l HCl lixiviant and run at ANSTO’s standard column operating conditions for the duration of the tests. The column tests were conducted over an 80 day period with samples still extracting rare earths at the end of this period.

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. 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). 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. 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. 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.

Certified reference samples, duplicates and blank samples were inserted into the drill sample stream such as to represent approximately 5% of the samples submitted to the laboratory for analysis Two composite samples were collected over three metre intervals – the first (the A sample) being submitted for laboratory analysis and the second (the B sample) being retained as a reference. A sample from each metre was collected and stored in a chip tray for logging and x-ray diffraction analysis. Drill intercept samples for the two heap leaching metallurgical composites were obtained from the ‘B’ samples located on the company’s Exploration Licenses. Samples were sent to ANSTO for making up the composites and completing the testwork. Air core drilling was completed by hammer and blade industry standard drilling techniques Aircore is considered to be an appropriate drilling technique for saprolite clay Drilling used blade bits of 87mmØ with 3m length drill rods to blade refusal. Air core recoveries were not recorded but are not considered to be materially biased, given the nature of the geology and samples. The assay data will be analysed against control samples and historical assays for any indications of bias All chips were logged qualitatively and quantitatively. A sample from each metre was collected and stored in a chip tray for logging Geological logs recorded lithology, colour and weathering. A composite sample of ~ 3kg for analysis was taken using a scoop from each metre pile to subsample 1 to 1.5kg sample. This was then dispatched to the laboratory. A second composite sample was similarly taken and stored on site as a reference Air core samples were a mix of wet and dry Certified reference samples, duplicates and blank samples were inserted into the sample stream such as to represent approximately 5% of the samples submitted to the laboratory for analysis 11 Criteria JORC Code explanation Commentary • 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.
