OD6 Metals Limited (ASX: OD6) is advancing the Gulf Creek Copper Project in northern New South Wales, a historically mined, high-grade copper system. The Company has completed a Downhole Electromagnetic (DHEM) survey to support its recent diamond drilling program and improve targeting beneath historic workings.

Samso continues to follow OD6 Metals Ltd (ASX: OD6) as it advances Splinter Rock from resource definition into processing optimisation and commercial readiness. This update is relevant as it focuses on metallurgical de-risking, product qualification, and offtake preparation rather than exploration upside alone, which is a key transition phase for clay-hosted rare earth projects.

OD6 Metals Ltd (ASX: OD6) has commenced a Downhole Electromagnetic (DHEM) survey at the Gulf Creek Copper Project, located near Barraba in northern New South Wales (Figure 1). The program marks a significant technical step forward in assessing the project’s volcanogenic massive sulphide (VMS) copper potential, following the completion of four diamond drill holes and earlier reverse-circulation (RC) drilling completed in 2025.

OD6 Metals Ltd (ASX: OD6) is shaping into one of Australia’s most strategically positioned critical-minerals developers, underpinned by two assets: Splinter Rock Rare Earths Project & Gulf Creek Copper-Zinc Project. Both projects benefit from Tier-1 jurisdictions, with Splinter Rock tied directly into the Esperance Port corridor and Gulf Creek positioned within NSW’s Renewable Energy Zones.

OD6 Metals Limited (ASX: OD6) has announced the publication of a peer-reviewed scientific paper detailing three years of advanced geological and geochemical work at the Company’s flagship Splinter Rock Rare Earth Project in Western Australia (Figure 1). The research—undertaken by CSIRO, Murdoch University, Monash University, and OD6—provides a technical, science-backed understanding of how rare earth elements (REE) occur, concentrate, and can be extracted from this large clay

OD6 Metals Limited (ASX: OD6) commenced Phase 2 drilling at the 100%-owned Gulf Creek Copper Project (NSW), advancing the first modern program over a historically high-grade VMS system. The campaign targets along-strike repeats of the Gulf Creek mine stratigraphy where magnetics, jaspilite exhalites, and surface pathfinders coincide (Figure 1).

OD6 Metals (ASX: OD6) has wrapped up its CPC Optioneering Study—backed by ANSTO testwork—and selected a preferred process flowsheet for the clay-hosted rare earths at Splinter Rock. The decision lifts confidence that OD6 can produce low-impurity MREC/MREH products and moves the project into large-scale optimisation at ANSTO alongside the commencement of mining studies at the Inside Centre Deposit

OD6 Metals Limited (ASX: OD6) has launched a metallurgical diamond core drilling campaign at its 100%-owned Splinter Rock Rare Earth Project in Western Australia. This work is focused on Inside Centre, the deposit that has consistently delivered standout metallurgy and supports near-term development studies.

OD6 Metals Limited (ASX: OD6) has released results from its CPC Engineering Optioneering Study, confirming that heap leaching is the lower-cost and preferred primary leach option for the Splinter Rock Rare Earth Project (Figure 1). This is a significant step in de-risking the project and optimising development economics, with the study showing heap leach delivers superior recovery, lower capital intensity, and simplified operations when compared to conventional agitated tank
