Air core drilling across ChemX Materials’ Eyre Peninsula tenements in South Australia has turned up what the company calls “outstanding” results.
The materials technology company – which is focused on providing critical materials for electrification and decarbonisation – said an initial batch of reconnaissance rare earths elements (REE) assays have highlighted the prospectivity of the location for ionically adsorbed REE.
The recent regional discoveries of REE surrounding the company’s tenements share very similar geology. The remainder of samples collected from the maiden drill program will be further assayed to provide a solid understanding of the distribution of REE through the clays.
ChemX’s Eyre Peninsula tenements cover the Kimba Kaolin-Halloysite Project and Jamieson Tank, which historically has been explored for manganese. The air core program returned high REE results at both Kimba and Jamieson Tank.
The company’s second foundation focus, in line with targeting critical materials for electrification and decarbonisation, is the development of a High Purity Alumina (HPA) plant in Western Australia using ChemX’s in-house HiPurA process.
ChemX Materials managing director David Leavy said the next stage was to further confirm the extent of the mineralisation within the results of the samples currently in the laboratory and undergoing beneficiation in preparation for assaying.
“This will include developing an understanding of the presence and distribution of high-value magnet rare earths – neodymium, praseodymium, dysprosium and terbium,” he said.
“We will also be undertaking metallurgical test work to determine the optimum process to maximise the recoverability of REEs from the host clays.”
