Proceeds will accelerate rare earth testwork and development studies at the Company’s flagship Splinter Rock Rare Earth Project in Western Australia (WA), progress offtake discussions with international parties, and fund Phase 2 drilling at the high-grade Gulf Creek Copper Project in New Sout Wales (NSW). Funds will also be used for general working capital. Commenting on the capital raising, OD6’s Managing Director, Brett Hazelden, said: “This capital raise provides the funding needed to maintain strong momentum across both our Splinter Rock and Gulf Creek projects. At Splinter Rock, our partnership with ANSTO continues to deliver processing breakthroughs, with the successful production of a high-quality Mixed Rare Earth Carbonate. The next step is to scale up testwork and generate sufficient product to support advanced offtake discussions with potential partners in Asia, Europe and North America. At Gulf Creek, Phase 2 drilling is scheduled to commence in September. This program will test multiple high-priority targets at Big Bend, West Limb and North West, as well as deeper extensions below historical workings. We are excited to build on our successful maiden program, which confirmed Gulf Creek’s potential as a significant high-grade copper system. We thank both new and existing investors for their strong support of OD6’s growth strategy.” Placement The Placement comprises the issue of 38,461,538 new fully paid ordinary shares (New Shares) to raise A$2.5 million, with 22,414,743 New Shares to be issued pursuant to the Company’s remaining 15% placement capacity under ASX Listing Rule 7.1 and 16,046,795 New Shares to be issued pursuant to the Company’s 10% placement capacity under ASX Listing Rule 7.1A.

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. 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 the largest and highest-grade clay-hosted rare earths deposit 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 development which utilises the large and high-grade Splinter Rock resource to support a long-life REE operation supported by a low strip ratio Corporate Directory Managing Director Mr Brett Hazelden Non-Executive Chairman Mr Piers Lewis Non-Executive Director Dr Mitch Loan Financial Controller/ Joint Company Secretary Mr Troy Cavanagh Joint Company Secretary Mr Joel Ives Contact Investor Relations OD6 Metals Ltd Lucas Robinson ACN 654 839 602 Corporate Storytime www.od6metals.com.au lucas@corporatestorytime.com Mail to: info@od6metals.com.au Phone: +61 408 228 889 Phone: +61 8 6189 8515 Level 1, 1 Alvan Street, Subiaco, WA 6008 3 Forward Looking Statements Certain information in this document refers to the intentions of OD6 Metals, however these are not intended to be forecasts, forward looking statements, or statements about the future matters for the purposes of the Corporations Act or any other applicable law.
