Announcement PDF ASX Announcement 12 March 2025 ASX: OD6 Exploration Update: Gulf Creek Copper Project OD6 Metals Limited (OD6 or the Company) provides an update on exploration activity at the Gulf Creek Copper Project, located in northern New South Wales. The Company advises that wholly owned subsidiary Gulf Creek Copper Pty Ltd has been issued with a notice by the NSW Resources Regulator with directions to cease exploration activities associated with EL 8492 at the Gulf Creek Copper Project. The notice followed an on-site inspection by the NSW Resources Regulator which identified concerns, which the Company is addressing. At the time of receiving the Notice, the Company was part way through the initial drill program at Gulf Creek (refer announcement dated 24 February 2025), with a total of 1,113 metres having been drilled in 6 drill holes of the initial 9 hole, ~2,000 metre program. The Company is confident it can work positively with the NSW Resources Regulator to address their concerns and recommence exploration activities. In the meantime, the Company is conducting corrective actions and will provide an update regarding recommencement of exploration activities in due course. The Company anticipates that assay results from the completed drill holes will be received within the next 4 weeks, following which the Company intends to assess the forward program, including planning of extensional drilling. 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 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
