ChemX Materials announced the Kaolin results from the 2022 aircore drilling campaign at its Kimba Kaolin-Rare Earth Elements (REE) project on the Eyre Peninsula in South Australia. Final assays from Kaolin-REE targets at the Company's Eyre Peninsula tenements further confirm the potential for world-class Kaolin deposits Kaolin drill hole results assayed at near pure Kaolinite grades, with very low contained deleterious elements The above significant intercepts are from 363 sub 45-micron sample results across 80 drill holes. Pure Kaolinite has the formula Al2Si2O5(OH)4 and consists of approximately 39.5% Al2O3, 46.6% SiO2 and 13.9% H2O.

Assay results indicate the presence of significant volumes of Kaolin with grades above 36% Alumina (Al2O3) with Alumina ranging from 14.2% (low) to 38.2% (high) with the average and median of 33.5% and The reported assay results are significant for ChemX as it seeks to develop a suite of high value criticalmaterials for the electrification and decarbonisation markets. Kaolin samples obtained from the exploration program will now undergo calcination testwork to produce metakaolin, followed by further evaluation for use in cement-based products to reduce carbon emissions in the cement production process. High grade kaolin associated with REE enrichment has the potential to improve the overall economics of the project should it proceed to development.

Additional investigation as to key qualities may be undertaken at a later stage to determine otential economics of the project, including: · Brightness, quantitative XRD (and SEM) analyses · Infill and extensional aircore drilling to improve confidence in continuity of geology, grade and quality. Determination of in situ bulk density by relevant methods · Calcination to an anhydrous aluminium silicate form increasing whiteness, hardness, size and shape for further downstream uses.ChemX's Eyre Peninsula projects are situated nearby to established major infrastructure (road, rail and port) routes, each of which have the potential to significantly enhance the economics of any project development. Kaolin has many uses, ranging from paper coating, fiberglass, ceramic ware and geopolymers.

The high quality of ChemX's kaolin will enable its use in high value markets.
