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 i n 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 minestratigraphy, 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 Non-Executive Chairman Non-Executive Director Mr Brett Hazelden Mr Piers Lewis Dr Mitch Loan Financial Controller/ Joint Company Secretary Joint Company Secretary Mr Troy Cavanagh Mr Joel Ives Contact Investor Relations OD6 Metals Ltd Lucas Robinson ACN 654 839 602 www.od6metals.com.au Mail to: info@od6metals.com.au Corporate Storytime lucas@corporatestorytime.com Phone: +61 408 228 889 Phone: +61 8 6189 8515 Level 1, 50 Kings Park Road, West Perth, WA 6005 PO Box 277, North Beach, WA 6920 PO Box 2009, Esperance, WA 6450 3
