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 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

OD6 Metals Limited (ASX: OD6) has announced a significant step forward in rare earth processing at its flagship Splinter Rock Rare Earth Element (REE) Project in Western Australia (Figure 1).
