Lanthanein uncovers ‘exceptional’ Koolya Kaolin results

Lanthanein Resources (ASX:LNR) has returned ‘exceptional’ results following a first pass aircore (AC) drilling program at its Koolya Kaolin Project in Western Australia. 

The results, generated by the wide-spaced drill program completed in December 2022, are reported to have intersected widespread kaolin of varying thickness, with a best result of 30m thick, bright white kaolin from 4m depth in drillhole KAC014. 

Lanthanein reports analysis has also been completed on samples in order to quantify specific characteristics, such as ISO brightness, alumina content, and rare earth elements (REEs). Analysis delivered ‘exceptional’ results up to 94.57%, with a further 10 samples demonstrating an ISO brightness of 79.35% and 4 samples showing total rare earth oxide (TREO) grades of 1,220 parts per million.  

Further analysis is expected to be further undertaken to better quantify the presence of kaolinite and halloysite using XRD analysis in Q2 and Q3 in order to assist with the generation of a Mineral Resource Estimate (MRE) by Q4, 2023.      

Commenting on the results, Lanthanein Technical Director, Brian Thomas says: “The exceptional brightness results in samples from our first pass aircore drilling at Koolya Project is a great result. There is a significant areal extent of the high quality bright white kaolin to support the potential for a significant kaolin resource and high purity alumina feedstock project to be delineated with further drilling. 

“There is a significant areal extent of the high quality bright white kaolin to support the potential for a significant kaolin resource and high purity alumina feedstock project to be delineated with further drilling” 

These recent results are in line with our expectations following the exceptional visual results in drill samples. High purity kaolin is of growing importance as a critical feedstock in the processing of high purity alumina (HPA) which is being used in Li-ion batteries, LED lighting, semiconductors and sapphire glass. Samples are also currently being analysed by x-ray diffraction (XRD) to quantify the kaolinite/halloysite content. Halloysite can be used in nano technologies for a range of industry applications including carbon sequestration, agriculture, energy, and health. 

We are also greatly encouraged by the presence of REEs with values of up to 1,220ppm TREO. 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.”   

The company also notes kaolin assays demonstrate very low contained deleterious elements. 

Additionally, Lanthanein says these results come following the start of drilling at its Murraydium Rare Earths Project in South Australia, as announced by the company late last month. 

Lanthanein Resources is an ASX-listed company emerging as a rare earth explorer and working towards building a sustainable electric future. The company is focused on the discovery of critical minerals of REEs in Western Australia and South Australia. 

The Koolya Project is located 460km east of Perth within a region of proven ‘high quality’ kaolin producing region with Tellus Holdings Sandy Ridge kaolin mine 30km away to the northeast. The project is considered prospective for bright white kaolin and high purity alumina across a 240km-square land area and hosts tenure supportive for large-scale development.
