RareX (ASX: REE) has shown its confidence in the Mt Mansbridge xenotime heavy rare earths project by adding further exploration ground to the Western Australian asset.The WA Department of Energy, Mines, Industry Regulation and Safety has notified RareX that it has granted tenements E80/5942 and E80/5973 within the project area.Xenotime is a rare-earth phosphate mineral that is a rich source of yttrium—a proxy element for the heavy rare earths used in many high-tech industries, including wind turbines, hybrid cars and electronic components.Browns Range similaritiesThe push to expand Mt Mansbridge follows a recent assessment of the project that identified similarities to Northern Minerals’ (ASX: NTU) nearby Browns Range heavy rare earths project.Mt Mansbridge is located just 40 kilometres from Browns Range, considered one of the most significant heavy rare earth districts in the world with seven xenotime deposits hosting 11.7 million tonnes at 0.77% total rare earth oxide.RareX chief executive officer James Durrant noted that the geology at the Mt Mansbridge and Browns Range projects is closely aligned, with Mt Mansbridge featuring the same unconformity contact that hosts the high-grade Browns Range deposits.Outcropping xenotime mineralisation has been identified with historical pit samples at Mt Mansbridge and RareX sees significant exploration upside at the project including a 2km-long untested heavy rare earths soil anomaly.The company has scheduled heritage clearances for high priority areas within the project.It has also pegged a fourth, 40-block tenement (E80/6118) at Mt Mansbridge that is expected to be granted later this year.Substantial exploration package“The land package at our Mt Mansbridge heavy rare earths project is now substantial and ready for exploration,” Mr Durrant said.“We know there’s xenotime mineralisation on the project, we know the region and the native title holders well and we know the strategic nature of heavy rare earths to Australia.”“This project aligns with our focus on rare earths and niobium, supporting the global electrification megatrend—we look forward to progressing exploration activities and unlocking the full potential of this promising project.”
