Brett Hazelden, Managing Director, commented: “OD6 has worked positively with the NSW Resource Regulator to identify a path forward to enable recommencement of exploration activities at Gulf Creek. We look forward to updating the market on our Maiden drill programs assay results shortly, with the initial six completed drill holes expected to guide further ongoing exploration drill programs associated with both the brownfield area at the historic Gulf Creek Mining Area, and the greenfield opportunities at the potential repeat structures already identified and yet to be tested.” This announcement has been authorised for release by the Board of OD6 Metals Limited 1 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. Copper The Company is advancing the recently acquired 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. Mineralisation is associated with magnetite, with geophysics showing significant greenfields and brownfields exploration potential exists with 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 on of 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 Dr Darren Holden Non-Executive Director 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, 50 Kings Park Road, West Perth, WA 6005 PO Box 277, North Beach, WA 6920 PO Box 2009, Esperance, WA 6450 2 No new information Except where explicitly stated, this announcement contains references to prior exploration results, all of which have been cross-referenced to previous market announcements made by the Company.
