This work has led to a preferred flowsheet being selected which has a high quality, low impurity and high payability product. With a $2.5M capital raise also completed we have been able to fast track metallurgical core drilling at our Inside Centre Project at Splinter rock so that advance scale-up testwork can occur at ANSTO. The drilling is now completed and ANSTO is looking to commence works in November. A key part of this test work is producing customer product samples that will be available in the new year for ongoing offtake discussions. We are also excited to have the drill rig back out at our Gulf Creek Copper Project in NSW. The drilling program is scheduled to be completed by December with assays to follow with any luck prior to Xmas or in January. The best place to look for a copper project is under or next to an old mine, especially with copper prices now above US$11,000/t.“ Exploration and Development (including subsequent events) Splinter Rock Rare Earth Project, WA Innovative Process Flowsheet Selected With High Recoveries During the quarter OD6 released a series of ASX announcements associated with Phase 4 metallurgical testing undertaken at ANSTO over the last 12 months, along with outcomes from the CPC Engineering (CPC) Optioneering Study. These announcements culminated in an innovative process flowsheet with high recoveries being selected (refer ASX release 1 October 2025), In summary OD6, CPC and ANSTO have successfully demonstrated and recommended a multi-stage processing pathway outlined in Figue1, 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 Innovative Process Flowsheet Incorporates • Heap Leach with Nanofiltration (NF), Ion Exchange (IX) and Impurity Removal (IR) • ~75% Nd & Pr overall Recovery • High-quality Mixed Rare Earth Carbonate (MREC) of ~56% TREO • High-quality Mixed Rare Earth Hydroxide (MREH) of ~59% TREO • Superior product quality with low levels of impurities (Al, Fe, P, Si) • Extremely low uranium and thorium content (<0.001% U + Th) • Optimised capital and operating cost drivers 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) 3 Figure 1: Preferred Process Flowsheet from ANSTO Testwork and CPC Optioneering Study Figure 2: Anticipated Inside Centre Total REE Recovery by Element Utilising the Preferred Process Flow Sheet Nano Filtration Reduces Acid Requirements by over 80% At the start of August (refer ASX 4 August 2025) OD6 reported: • Outstanding 84.5% acid recovery achieved utilising Nanofiltration (NF) technology • Significantly lower acid requirements set to drive major decrease in processing costs and improve project economics • No loss of Rare Earth during acid recovery process • 69% reduction in liquid volume sent to Impurity Removal (IR) Circuit • Smaller IR circuit size expected to materially reduce both capital and operating costs 0 10 20 30 40 50 60 70 80 La Ce Pr Nd Sm Eu Gd Tb Dy Ho Er Tm Yb Lu Y TREY Total REE % Recovery Inside Centre Deposit Extraction by REE 4 What is Nanofiltration? Nanofiltration (NF) is a pressure driven membrane filtration process that uses liquids to selectively separate substances based on size and charge. Its primarily used for water purification, for example to remove hardness (calcium and magnesium), sulphates and organic compounds (Figure 1). It sits between reverse osmosis and ultrafiltration in terms of pore size, pressure requirement and selectivity. Ion Exchange Technology Improves Process Flowsheet Following the Nanofiltration announcement, OD6 reported on the use of Ion Exchange Technology to Further improve the Process flowsheet (refer ASX 7 August 2025): • Ion Exchange (IX) resin technology enhances removal of iron (Fe) and aluminium (Al), improving product purity and reducing downstream processing risk • Successful development of uranium (U) and thorium (Th) removal circuit improves product payability and expands potential global offtake markets • Minimal Rare Earth Element (REE) loss (<1%) during IX process • IX further improves the downstream scale of the IR Circuit which is expected to further optimise both capital and operating costs • Optimised Impurity Removal (IR) Precipitation and Mixed Rare Earth Carbonate (MREC) separation processes • Enhanced process efficiency and product quality expected to materially improve project economics What is Ion Exchange? Ion Exchange (IX) is a chemical process where ions are swapped between a solution and a solid material (usually a resin). In rare earth processing, ion exchange is used to concentrate rare earth elements from complex mixtures. In our case we are looking to decrease Aluminium (Al) and Iron (Fe) content to improve downstream Impurity Removal (IR) and Mixed Rare Earth Carbonate (MREC) quality. Further Uranium (U) and Thorium (Th) can be selectively removed from the final product to enable safe transport and refining. An analogous process is the use of carbon in gold leaching, whereby gold in liquid is absorbed onto carbon, then eluted into solution for electrowinning. High Quality MREC Produced Based on the addition of both NF and IX the Company in conjunction with ANSTO was able to produce a High Quality Mixed Rare Earth Carbonate (MREC) and Mixed Rare Earth Hydroxide (MREH). • High-quality Mixed Rare Earth Carbonate (MREC) of ~56% TREO produced • High-quality Mixed Rare Earth Hydroxide (MREH) of ~59% TREO also produced utilising the same process but utilising Sodium Hydroxide (NaOH) to precipitate the saleable product • The significant MREC and MREH production results position the company to deliver a premium product, distinguishing it from peers and ranking it among the top global rare earth projects. Key highlights include: o +90% of product value expected from Magnetic Rare Earth content (Nd + Pr + Dy + Tb) o Superior product quality with low levels of impurities (Al, Fe, P, Si) o Extremely low uranium and thorium content (<0.001% U + Th) o No expected refinery penalties, ensuring optimal commercial payability. 5 • OD6's product quality meets or exceeds global MREC and MREH benchmarks, positioning it for premium payability and a competitive advantage in future offtake agreements. • The company is engaging with potential offtake partners to assess commercial payability options, while expanding its network of potential high-value downstream customers across North America, Europe, and Asia. MREC and MREH Results Sodium Carbonate (Na2CO3) or Sodium Hydroxide (NaOH) has been utilised to precipitate a Mixed Rare Earth Carbonate (MREC) or Mixed Rare Earth Hydroxide (MREH) respectively. Precipitation occurs from a starting point of ~4.1 to 4.4 pH to a finish pH of between 7.1 to 7.5. This occurs post the two stage Impurity Removal (IR) precipitation process that has been enhanced by NF and IX to minimise REE co-precipitation losses and maximise overall REE recovery - refer to Figure 3 below. The MREC and MREH precipitate is then washed with deionised water to remove and residual salts (eg Na, Cl) prior to being dried and assayed. Benchmark payability for MREC and MREH typically ranges between 70–85% of REO basket value, depending on impurity levels and buyer requirements. These results position OD6 for premium payability in future offtake discussions. The high quality and low impurity nature of the product also opens access to multiple potential downstream customers globally, including separation plants in Asia, Europe and North America. Further refinement of the MREC and MREH Composition will continue during the next phase of testwork, studies and feedback from potential customers. Figure 3: Impurity Removal Curve showing decreasing Al and Fe concentration as pH is increased Chlor-Alkali Facility to Lower Operating Costs At the start of September (refer ASX 2 September 2025) OD6 reported: • Chlor-Alkali Facility (CAF) confirmed as a cost-reduction measure, producing key reagents onsite and materially lowering operating costs • Onsite production of Hydrochloric Acid (HCl) and Sodium Hydroxide (NaOH) eliminates expensive transport of liquid reagents from Perth (~800km) reducing environmental footprint 6 • Abundant and low-cost solar sea salt (NaCl), extensively produced in Western Australia, provides the primary feedstock alongside water and energy • Financial metrics significantly improved through lower reagent costs and reduced logistics • CAF enables potential selective production of Nd, Pr, Dy, Tb oxides via a chloride- based Solvent Extraction (SX) process What is a Chlor-Alkali Facility? A Chlor-Alkali Facility (CAF) is a plant that produces two essential chemicals, Hydrochloric Acid (HCl) and Sodium Hydroxide (NaOH), from Salt (NaCl) and Water: How It Works The Chlor-Alkali process relies on electrolysis, splitting salt (NaCl) dissolved in water into its components. In short, an electric current passes through the salt brine to produce hydrogen, chlorine and sodium hydroxide. The hydrogen and chlorine can then be combined into hydrochloric acid. The equations to create sodium hydroxide (NaOH) and hydrochloric acid (HCl) are: 2H2O (l) + 2NaCl (aq) —-> H2 (g) + Cl2 (g) + 2NaOH (aq) H2 (g) + Cl2 (g) —–> 2HCl (g) Optioneering Study Supports Heap Leaching as Low Cost Route The first of CPC’s Optioneering Outcomes (refer ASX 11 September 2025) validated heap leaching as the lower-cost and preferred primary leach option for the Splinter Rock Rare Earth Project: • Heap leach confirmed lower cost than agitated tank leach for Splinter Rock’s clay-hosted rare earth mineralisation, based on CPC Engineering’s multi-criteria optioneering assessment. • Superior Recovery: Heap Leach offers a higher recovery than the equivalent tank leach process • Lower Capital requirements anticipated: Simplified process eliminates large leach tanks, clay-washing, and complex separation circuits, and allows for modular, scalable construction. • Lower operating cost drivers: Reduced energy and maintenance intensity; Chlor- Alkali Facility enables on-site reagent generation in conjunction with acid recycling benefits, further de-risking operating costs. • Process innovation maintained: Heap leach liquor enables OD6’s downstream flowsheet to utilise Nanofiltration (NF), Ion Exchange (IX), targeting a high-quality and low impurity Mixed Rare Earth Carbonate (MREC) product. • High-quality MREC product: Heap leach integrates with OD6’s downstream process to produce a premium, low-impurity MREC. OD6 plans to rapidly scale-up testwork to produce MREC samples for offtake discussions. • Fit-for-purpose: Study supports the suitability of the simplified heap leaching and Impurity removal process for Splinter Rock’s mineralisation style and planned scale. • Positive Study Outcomes: The results from the optioneering study to date are positive and the results justify progression of further exploration, testwork and study investigations. 7 Metallurgical Diamond Core Drilling Completed at Splinter Rock During the quarter OD6 Commenced (refer ASX release 17 September 2025) Metallurgical Diamond Core drilling , which was completed subsequent to the end of the quarter (refer ASX release 9 October 2025). Core samples will be sent to ANSTO as part of the planned optimisation and scale-up program aimed at refining the heap leach and impurity removal flowsheet and providing final product samples for offtake discussions. Six Metallurgical drill locations have been completed (Figure 4) utilising PQ diamond core (85mm core), which have been twinned next to existing AirCore drill hole locations previously utilised metallurgical testwork conducted at ANSTO. The diamond drilling program targeted key areas of the Inside Centre Deposit, designed to obtain representative material for metallurgical and processing testwork. The bulk rare earth bearing material will provide ~2.0 to 2.5 tonnes of core samples that were logged and prepared for dispatch to ANSTO in Sydney. Figure 4: The Inside Centre Indicated Resource (shown in red) and the selected holes twinned (shown in yellow). The figure also shows the Existing Centre Inferred Resource (shown in orange) plus shows mineralisation remains open to the SW and NE within the modelled clay basin airborne electromagnetic survey ANSTO Scale-up Testwork Program The metallurgical core program has targeted zones within Inside Centre that best represent an area of consistent geology, prior metallurgical outcomes, low striping ratios, significant grades and planned early-stage mining areas. Samples will be composited at ANSTO for a series of advance campaigns focused on: • Heap leach Optimisation; o Heap Leach duration and kinetics o Acid strength and consumption o Counter current heap configuration o Particle agglomeration methodology 8 • Impurity Removal Verification: o Nanofiltration (NF) acid recovery and liquor concentration tuning o Ion Exchange (IX) selectivity and elution to reduce Fe/Al and trace U/Th prior to precipitation o Impurity removal (IR) two stage pH optimisation to achieve target impurity specifications • 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 for the products. Pathway to Offtake The core program directly supports OD6’s ongoing testwork and studies with ANSTO and CPC Engineering by supplying bulk test material and enabling production of more than 1 kg of a premium, high grade and low impurity Mixed Rare Earth Carbonate (MREC) and Mixed Rare Earth Hydroxide (MREH). Offtake Samples of MREC and MREH can then be sent to global separation facilities that will be utilised for offtake discussions and to assess commercial payability options for the products. Engagement with potential offtake partners is continuing. Gulf Creek Copper Project, NSW Phase 2 Drilling Commenced at Gulf Creek Copper Project Subsequent to the end of the (refer ASX release 14 October 2025) the Company commenced Phase 2 drilling at the Gulf Creek Copper Project. Phase 2 drilling will test potential extensions to mineralisation near the historic Gulf Creek Copper mining area. These repeat structure targets, named Big Bend, North West and West Limb (refer to Figure 5 and 6) are along strike to the northwest of the Gulf Creek mineralisation and feature substantial magnetic anomalies which mirror the Gulf Creek magnetic signature. The presence of the jaspilite capping the mineral system, and the strong magnetism associated with semi-massive sulphide mineralisation indicates that the Big Bend, North West and West Limb remain excellent untested targets. The observations from the drilling completed to date are consistent with a “Besshi” volcanic hosted massive sulphide (VMS) system, which are known to occur in clusters: The three prospects to be tested represent a portion of ~3km of untested strike in the immediate Gulf Creek mine stratigraphy. An initial 7 priority holes at Big Bend, North West and West Limb Targets have been identified for ~1,750m. OD6 has received approvals from the NSW Resources Regulator for 25 drill holes totalling ~7,500m. Downhole EM is planned to be undertaken post drilling to further identify follow up targets. 9 Figure 4: Long Section view to SW showing extended view of geophysical modelling and the targets along the West Limb of the Gulf Creek Syncline to the NW anomaly.
