Lanthanein Resources Ltd (ASX:LNR) has unearthed widespread kaolin of varying thickness during its first pass aircore drilling program at the Koolya Kaolin and High Purity Alumina Project in Western Australia.
Bright white kaolin measuring 30 metres thick was intersected from a depth of 4 metres in the program which covered 15 kilometres of prospective kaolin-rich granite.
Samples have been sent to ALS Laboratories to quantify the specific characteristics such as brightness, alumina content, presence of halloysite and rare earth elements (REE), with results expected in the first quarter of 2023.
Further infill and step-out drilling will be conducted to complete a mineral resource estimate aimed for the second half of next year.

Exceptional results
“Our first pass aircore drilling has returned exceptional visual results, highlighting a significant areal extent of high-quality bright white kaolin at our Koolya Project in Western Australia,” Lanthanein technical director Brian Thomas said..
“High-purity kaolin is of rising importance as a critical mineral due to the processing into high-purity alumina (HPA) which is being used in Li-ion batteries, LED lighting, semiconductors and sapphire glass.
“Samples will also be sent for dual analysis for rare earths and to identify if the mineral halloysite is present. Halloysite can be used in nano technologies for a range of industry applications, including carbon sequestration, agriculture, energy, and health.
“Exploring for critical minerals and rare earths is of paramount importance for our company as we aim to find the future-facing minerals used in the global clean energy transition.”
