Our strategic entry into the US critical minerals sector through the Quinn Fluorspar acquisition positions the Company at the intersection of two compelling investment themes - critical minerals supply security and the re-shoring of US strategic supply chains. Quinn represents exactly the type of opportunity we seek: a district-scale system with ultra high-grade historic results, located in a Tier-1 mining jurisdiction, with clear strategic value to the United States. Nevada's ranking as the world's number one mining jurisdiction, combined with the US Government's focus on critical minerals independence, creates an exceptional backdrop for project advancement. At Splinter Rock, our ANSTO Phase 5 metallurgical program continues to de-risk the processing pathway. The production of bulk MREC and MREH samples will enable meaningful offtake discussions with potential partners seeking secure rare earth supply. The appointment of The Hon Julie Bishop as Strategic Advisor underscores our commitment to advancing government and stakeholder engagement across both Australian and US critical minerals initiatives. Her extensive experience in international relations and policy development will be invaluable as we progress both Splinter Rock and Quinn."

Samples will be composited at ANSTO for a series of advanced 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 • 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 o Precipitation to produce >1 kg of MREC and/or MREH for customer qualification, offtake discussions, and to assess commercial payability options for the products. • Other Elements of Interest o The program will monitor various other elements of interest to determine if there is a technically viable approach to recovery. The work program is designed to de-risk the processing flowsheet, improve confidence in operating parameters, and provide commercially relevant products that support offtake engagement, financing discussions, and future technical studies. 12 Figure 10: Preferred Process Flowsheet from ANSTO Testwork and CPC Optioneering Study Figure 11: Anticipated Inside Centre Total REE Recovery by Element Utilising the Preferred Process Flow Sheet Critical Minerals Reserve Strategy The Company confirmed its role, alongside a consortium of industry participants, in contributing to the industry-led framework supporting Australia’s Critical Minerals Strategic Reserve (CMSR), as advanced by the Association of Mining and Exploration Companies (AMEC) (refer ASX 14 January 2026) The CMSR concept paper (refer AMEC CMSR) provides a strategic policy framework for ggovernment consideration. This framework seeks to articulate how a sustainable, bankable CMSR mechanism could be structured, to deliver greater market certainty for producers, strengthen supply chain resilience, and support long-term offtake pathways for critical minerals including rare earth elements. OD6’s participation reflects its commitment to advancing Australia’s role as a secure global supplier of strategically important minerals. 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 13 Source: AMEC Critical Mineral Strategic Reserve (CMSR) webpage (link here) Down Hole EM Identifies Off Hole Conductors During the quarter OD6 advised that processing and interpretation of the Downhole Electromagnetic (DHEM) survey completed in December 2025 has identified a strong off- hole conductors at the Gulf Creek Copper Project (refer ASX 23 January 2026). The newly identified strong conductor is located proximal to historic high-grade copper workings and represents a compelling new drill target, supporting the potential for fault- offset or stacked mineralised lodes beneath the historic mine. What is DHEM? Downhole Electromagnetics (DHEM) is a geophysical method where an electromagnetic field is transmitted from a surface loop and measured by a probe lowered down a drill hole. Because copper sulphides (chalcopyrite, bornite, chalcocite) are significantly more conductive than surrounding host rocks, the DHEM tool can detect: • Off-hole conductors, potentially massive sulphide bodies, not intersected by drilling • Down-dip, up-dip or along-strike extensions of mineralised lodes • Potential stacked or parallel lenses hidden from surface geophysics • Depth and orientation of conductive bodies to improve drilling accuracy DHEM is considered one of the most effective tools for vectoring toward massive sulphide accumulations, particularly in structurally complex or historically mined VMS systems such as Gulf Creek. DHEM can detect conductors at 50 to 100m from the drill hole. 14 A total of four EM surface loops were laid out over key target areas at Gulf Creek with six holes. This included 3 holes at Gulf Creek, and one hole each at the Big Bend, West Limb and Northwest Target areas. Results confirmed conductors associated with known high-grade mineralization proximal to the historic workings as seen in the upper areas of Figure 1. A strong off-hole conductor was detected beyond the end of hole GDD010 as indicated in the figure below. Hole GDD010 was drilled as a deep hole (EOH 328m) beneath the historic workings. Whilst the hole intersected only minor sulphide horizons it also did not intersect the known mine-stratigraphy including the main hanging-wall exhalite/jaspilite or the footwall basalt. The top part of the hole included silicified material, potentially indicating a fault zone. This suggests that there is a potential fault off-set, that steps mineralisation to the SW from a fault currently inferred to strike, parallel with the Gulf Creek syncline and dipping to the SW. DHEM Results from the Northwest target indicate a possible conductor, though in consultation with Mitre Geophysics, it requires further geological consideration before testing. DHEM at Big Bend and Western Limb did not yield appreciable off-hole conductors Figure 12: Cross-section SE-NW across Gulf Creek showing plate conductors 15 Corporate Half Year Accounts The Company released its Half Year Accounts for the period ended 31 December 2025 (refer 6 March 2026).

OD6 confirms that it is not aware of any new information or data that materially affects the information included in any original ASX announcement. 19 About OD6 Metals OD6 Metals is an Australian public company pursuing exploration and development opportunities within the critical minerals sector, namely rare earths, copper and fluorspar. 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). An innovative Process Flow sheet has been selected utilising Heap Leaching, Nano-filtration and Ion Exchange Technologies that have achieved ~75% Nd & Pr overall recovery, produced a high-quality Mixed Rare Earth Carbonate or Hydroxide (MREC/H) of ~56-59% TREO, with low levels of impurities (Al, Fe, P, Si) and extremely low uranium and thorium content. Fluorspar (Fluorite) The Company secured an option to acquire the Quinn Fluorspar Project in Nevada, USA. Nevada is regarded as one of the world’s premier mining jurisdictions and is currently ranked second in the 2025 Fraser Institute’s Mining Attractiveness Index. Historically a number of the Quinn Fluorspar deposits were mined in the 1950’s for Fluorspar. In 1969. The United States Geological Survey (USGS) conducted a survey and confirmed fluorspar grading up to 72% CaF2 in bulk samples. The USA currently imports 100% of all Fluorspar consumed domestically with 68% of all global supply sourced from China (USGS 2024). Fluorspar is listed as a Critical Mineral by the USGS and is essential in the production of hydrofluoric acid, AI semi-conductor chip etching, advanced battery technologies and nuclear fuel processing with other applications in defence and aerospace technologies. Copper The Company is advancing the Gulf Creek Copper-Zinc VMS Project located near the town of Barraba in NSW. 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
