Lanthanein’s first tilt at drilling for rare earths mineralisation at its Murraydium project in South Australia has returned encouraging early results.

Portable XRF (pXRF) analysis of the first phase of reconnaissance aircore drilling completed in the Bordertown Block returned consistent elevated levels (more than 1,000 parts per million) of neodymium and praseodymium (NdPr) in all 72 holes with a top result of 2,711ppm NdPr.

Notably for Lanthanein Resources (ASX:LNR), the target Loxton Parilla Sands are the same formation that hosts Australian Rare Earths’ Koppamurra Resource of 101Mt at 818ppm TREO.

All samples have been submitted to Bureau Veritas laboratory in Adelaide for confirmatory assay using industry standard chemical analysis, as pXRF is not a definitive measure of what is present.

“These results confirm the exciting exploration opportunity in a region that is highly prospective for ionic clay hosted rare earth deposits as evidenced by work done in the region by AR3 who have outlined an extensive mineralised system at Koppamurra where shallow near surface exploration has delineated significant JORC Resources of REE’s,” technical director Brian Thomas said.

“We are eagerly awaiting the return of the assays to confirm the presence of high-grade ionic clay hosted REE’s at the Bordertown Block of our Murraydium Project.”

Murraydium Project

Murraydium covers 872km2 of the Murray Basin in the southeastern region of South Australia.

It forms part of an extensive Tertiary strand plain comprising a series of sandstone‐dominant fluvial and beach‐dune strand complexes.

Extensive areas of the Loxton‐Parilla Sand are exposed at surface within the Bordertown Block where it typically forms rolling terrain of low sandy hills and ridges.
