Announcement PDF ASX Announcement 22 October 2025 ASX: OD6 2025 Annual General Meeting – Chairmans Address Good morning shareholders, It is a pleasure to address you today at OD6 Metals’ Annual General Meeting — my first as Chairman. The past year has been one of strong progress and strategic advancement for OD6, as we continue to position the Company at the forefront of Australia’s emerging critical minerals industry. It’s an extremely exciting time to be involved in rare earths with concentrated efforts from global policy makers to develop new supply chains in the industry. This has recently been evidenced by the US Government’s direct equity investment in the Mountain Pass, America’s largest rare earth producer. At Splinter Rock, near Esperance in Western Australia, OD6 continues to establish itself as a leader in the emerging clay-hosted rare earths sector. Through a combination of technical innovation and collaboration with respected research partners, we have made significant progress in developing a processing pathway that can deliver a high-value, low-impurity Mixed Rare Earth Carbonate product. This is a major step towards commercialisation, and we are now focused on scaling up testwork with ANSTO following the recent completion of our metallurgical core drilling program. The advanced testwork program will look to produce customer samples to enable offtake discussions, along with other works that will continue to progress the feasibility and financing pathways that will underpin development. We were also pleased to expand OD6’s portfolio through the acquisition of the Gulf Creek Copper Project in New South Wales. This historic high-grade copper project offers an exciting second growth pillar, complementing our rare earths focus and broadening our exposure to energy transition metals. Our Second phase drilling program focused on our green field repeat structures next to the old Gulf Creek Mining areas commenced last week and we look forward to keeping the market updated as the program progress and assays are received later this year. Together, Splinter Rock and Gulf Creek provide OD6 with exposure to two essential metals critical to the clean energy transition. On behalf of the Board, I would like to thank the dedicated OD6 team for their work throughout the year. I also extend my sincere appreciation to our shareholders for their continued support and confidence in OD6 Metals. We look forward to an exciting year ahead. Thank you …. we will now move to the formal business of the Meeting.

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.
