Announcement PDF ASX Announcement 7 May 2025 ASX: OD6 High-Grade Copper Massive Sulphides at Gulf Creek First holes drilled in 60 years at Golf Creek Copper Project return Volcanogenic Massive Sulphide (VMS) style copper-zinc-silver mineralisation in New South Wales. Highlights from first six holes at Gulf Creek: • Massive sulphide zones intersected extends copper mineralisation beneath historic workings • High Grade Drill results confirm historically mined mineralisation from surface and steeply dipping to the northwest associated with massive to semi-massive sulphide including: o 8m @ 1.41% Copper, 1.26% Zinc and 7.08g/t Silver in hole GCC0004 from 108m including: ▪ 5m @ 2.13% Copper, 1.82% Zinc, 10.74g/t Silver from 109m down hole o 6m @ 1.32% Copper, 2.82% Zinc and 9.02g/t Silver in hole GCC0006 from 116m o 1m @ 4.33% Copper, 1.02% Zinc and 2.5g/t Silver in hole GCC0001 from 67m (hole ended early due to the need to convert from RC to a diamond core tail which was unable to be undertaken) • Strong relationship between magnetism and massive sulphide mineralisation suggests potential large scale VMS system at Gulf Creek, with best intersections returned when targeting peak magnetic body • Magnetic modelling confirms potential repeat extensional target structures along strike, including the large Big Bend, Eastern Limb and Northwestern Zones as well as regional targets • Exploration is recommencing at Gulf Creek, with new geological interpretations to guide further drilling Brett Hazelden, Managing Director commented: “The results from the initial six holes in Phase 1 are excellent, with the presence of zones of massive to semi-massive sulphides that have significant grade and align well with the historic workings at Gulf Creek. We are also pleasantly surprised at the broad disseminated copper mineralisation seen from surface in three of the holes, suggesting the potential of a larger system. Most importantly we have confirmed the strong relationship between magnetism, mineralisation and classic VMS stratigraphy. The fact that the high-grade mineralisation is sitting immediately in the hanging wall of the strongest magnetic body confirms the Company’s targeting methodology. Importantly these drill results provide added confidence on our planned Phase 2 large scale greenfield extensional targets at Big Bend, West Limb and the Northwest Zone. These untested repeat magnetic structures cover an extent of ~3km, with a modelled depth to in excess of 500m, and were one of the key drivers for the acquisition of the Project. They remain compelling targets to progress, with the potential to obtain a significant scale project.” 1 About the First 6 holes at Gulf Creek The high-grade Gulf Creek Copper Project has historically only ever had two drill holes completed in the 1960s and has not been subjected to modern day exploration and been effectively drilled. The Company designed an initial 9-hole Phase 1 drill program, which was ceased early per directions received from the NSW Resource Regulator. OD6 has since received notice from the NSW Resource Regulator that exploration activities at Gulf Creek are now allowed to recommence. The results of the initial 6 holes are presented here. All holes in the initial program were designed to target the reported high-grade massive sulphide mineralisation historically mined at Gulf Creek and to also test the footwall magnetite rich components, including potential for massive magnetite-sulphide mineralisation. Further, this first phase of drilling utilised different geophysical targeting techniques including Induced Polarisation (IP) chargeability, drone magnetics and the recently completed fixed loop electromagnetics (FLEM). Down hole electromagnetics (DHEM) is intended to be undertaken on select holes in the future. Summary Results for the Initial Drilling at Gulf Creek The first hole GCC0001, was designed to intersect close to existing workings and test part of the IP anomaly. This hole intersected mineralisation up to 4.3% copper in massive sulphide, however the hole was ended early due to water and the need to convert from RC to a diamond core tail which was unable to be undertaken . The hole is intended to be extended with diamond core upon return of the drill rig. Hole GCC0002 was designed to test further mineralisation on extensional northwestern mineralisation, and intersected a maximum of 1m @ 0.25% Cu. Hole 3 tested below the mid strike position of historical workings but did not record any significant mineralisation. Holes GCC0004 intersected high-grade massive sulphide of 8m averaging 1.41% copper, 1.26% zinc and 7.08g/t silver including 5m averaging 2.13% copper, 1,82% zinc, 10.74g/t silver in a zone directly beneath historic workings. Similarly hole GCC0006 intersected 6m @ 1.32% copper, 2.82% zinc and 9.02g/t silver. The high-grade mineralisation (greater than 1% Cu, and up to 4.6% Cu) in holes GCC0004 and GCC0006 is associated with massive sulphide to semi-massive sulphide mineralisation dominated by pyrite, chalcopyrite and sphalerite. The hanging wall consists of sediments, with an exhalative jaspilite unit immediately above the main mineralised horizons. The footwall contains basalt and hydrothermal magnetite. Both holes were designed to test the strongest magnetic response underlying the historical workings of drone magnetic data. and confirmed the strong relationship between magnetism and mineralisation. The fact that the high-grade mineralisation is sitting immediately in the hanging wall of the strongest magnetic body confirms the Company’s targeting methodology. Hole GCC0005 was drilled off the southern end of the magnetic anomaly and intersected the mineralised horizon with up to 2.9% copper, 1.38% zinc and 72.4g/t silver. Silver mineralisation appears to be increasing in grade towards the south east. Positively, the drilling in holes GCC0003, GCC0004, GCC0005 and GCC0006 also intersected sediment hosted broad zones of highly anomalous copper in the near surface including; • 29m @ 0.16% Copper in hole GCC0004 from 3m • 19m @ 0.13% Copper in hole GCC0005 from surface • 15m @ 0.15% Copper in hole GCC0003 from 4m • 5m @ 0.28% Copper in hole GCC0006 from 0m The presence of broad, albeit low-grade, intersections is encouraging and indicative of multiple phases of mineralisation and is suggesting potential of a much larger system and the need for extensional exploration. Refer to the Figures below for further detail plus Appendix 1 and JORC Table 1 below for full drill hole details. 2 Figure 1: Chip Trays from Hole GC0004 showing the classic VMS stratigraphic succession from hanging wall sediments, jaspilite, disseminate to semi massive to massive sulphides to footwall basalts Figure 2: Massive sulphide pyrite-chalcopyrite-sphalerite in RC drill chips at 109m in hole GCC0004 3 Figure 3: Plan view of preliminary results Figure 4: Long section view SW showing increased grade and width with magnetic bodies. Refer to announcement dated 14 November 2024 for further details on geophysical modelling. 4 Figure 5: Cross-section through hole GCC0004 5 Implications for extensional exploration The main mineralised lode has now been confirmed over approximately 200m of drilled strike-length and is assumed to continue the length of the historic workings at over 300m of strike length. The main massive sulphide lens ranges from drilled widths of 1 to 2m thick in the NW and SE ends and up to 5 to 8m thick in the central part of the system (due to lifting of the dip of drill holes, the mineralised intercept is estimated to approximate 70% to 100% of true thickness. This high-grade and wide blow out zone is coincident with footwall basalts with elevated copper anomalism (100-400ppm) and increased magnetite including some evidence of whole drill chips >2cm of massive magnetite. Combined with a thickening of hanging-wall exhalative jaspilite cherts up to 20m thick above the strongly mineralised zones. The stratigraphic succession presented from sediments->hydrothermal magnetite altered basalt (anomalous in copper)>sulphides including high grade copper->jaspilites-sediments with disseminated mineral phases is a classic VMS stratigraphic succession. Given the strongest mineralisation is sitting immediately hanging wall of the strongest magnetic body confirms the Company’s targeting methodology using mapping of geochemically anomalous exhalite jaspilites and magnetic rich bodies (refer announcements 14 November 2024 and 19 February 2025). The Company intends to drill at least 1 deep hole (to approximately 400m) for down-hole geophysics as well as follow up on massive sulphide mineralisation intersected farther down dip. The presence of the jaspilite capping the mineral system, and the strong magnetism in the footwall of mineralisation indicates that the Big Bend, West Limb and Northwestern Zones remain excellent untested targets. The observations from the drilling completed to date are consistent with a “Besshi” volcanic hosted massive sulphide (VMS) system, which are known to occur in clusters.: • Big Bend – strong magnetism, surface jaspilites, increased IP geophysics effect, surface anomalism in Cu-Ce • West Limb Target 2 – strong magnetism, surface jaspilites, surface anomalism in Cu-Ce • Northwestern Target – strong magnetism, surface jaspilites, surface anomalism in Cu-Co-Ag-Be-Ce-Zn Figure 6: Long Section view to SW showing extended view of geophysical modelling and the targets along the West Limb of the Gulf Creek Syncline to the NW anomaly.

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 9 APPENDIX 1: Drill Hole Details Table 1.

Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems.

Other than state royalties, there is no overriding royalties on the project. The license overlaps both crown land (being the area principally of the historic mine) and private farmland. Private land holders in the area have previously consented to exploration activity on their land, and the Company knows no reason why on-going land access cannot be granted. The land falls in the area of claimants – the Gomeroi people. On private land, the native title has been extinguished. The area of Crownland was subject to a ruling 31/03/2022 and that Native Title is effectively extinguished for the purposes of exploration. Further consents may be required prior to mining. Heritage – areas subject to future ground disturbing work are subject to the NSW Mineral Industry Due Diligence Code of Practice for the Protection of Aboriginal Objects 2010. Historical archaeological sites are protected under the NSW Heritage Act (1977), which may be applicable to historic buildings and structures, including the presence of historic mine and smelter workings. Refer to ASX announcement 21 March 2025 regarding NSW Resources Regulator Notice Exploration done by other parties • Acknowledgment and appraisal of exploration by other parties. • The Gulf Creek mine has been subject to intermittent exploration for more than 100 years. In recent times, reconnaissance and geophysical surveys were carried out. Refer to ASX announcement 30 October 2024 for details. Geology • Deposit type, geological setting and style of mineralisation. • Base metal (copper and zinc) mineralisation occurs is massive to semi-massive sulphides principally chalcopyrite and sphalerite. The mineralisation is closely associated with magnetite. Mineralisation is hosted in a series of cherts, (sedimentary radiolarian and exhalative) siltstones and basalts of the Bob’s Creek Formation. The Bob’s Creek formation is underlain by the Woodsreef Formation- an ophiolite sequence including harzburgite, dunite and gabbro. Mineralisation is considered to be ‘Besshi Style’ Volcanogenic Massive Sulphide (VMS) deposit The sedimentary sequence, of which the mineralisation is parallel, has been folded into NW-SE striking and steeply dipping folds. At the historic Gulf Creek mine, mineralisation strikes NW-SE and is steeply dipping (70-85 degrees) to the NE. • • • • Drill hole Information • A summary of all information material to the understanding of the exploration results includi
