Announcement PDF ASX Announcement 4 February 2026 ASX: OD6 1 Research and Development Tax Offset Funds Received OD6 Metals Limited (OD6 or the Company) is pleased to announce that the Company’s 2024/25 Research and Development (R&D) Tax Incentive claim has been received. OD6 is registered for eligible Australian R&D activities at the Splinter Rock clay hosted rare earth (REE) project, located near Esperance in Western Australia. Highlights: • A$216,400 R&D tax offsets received for the 2024/25 financial year • Funds received reflect a rebate on eligible Australia R&D activities undertaken for the Splinter Rock clay hosted REE project. • The Company expects to continue R&D works and anticipates being able to claim future tax offsets over the coming years. • The Company is committed to R&D as it continues to develop critical minerals technologies through relationships with the CSIRO, ANSTO, private research providers and internally. Brett Hazelden, Managing Director, commented: “The R&D Tax Incentive program is an important scheme supporting OD6 and its partners, like CSIRO and ANSTO, to develop the technology to discover and extract the rare earth elements associated with our Splinter Rock clay hosted rare earth project. Critical minerals exploration, discovery and development is crucial to Australia and the world. The federal government’s support of the critical minerals industry is highly important to the future development of the Company and the resources industry. Over the last three years we have continued making solid advances at Splinter Rock including the recent production of a quality MREC from our heap leach and Impurity removal testwork, as we look to develop the necessary technology for a rare earth industry in the Esperance region of Western Australia.“ 2 About OD6 Metals OD6 Metals is an Australian public company pursuing exploration and development opportunities within the critical minerals sector, namely rare earths and copper. 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 (<0.001% U + Th). 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. 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.
