Summary
The document presents the results of the Sandy Mitchell project by Ark Mines Limited, focusing on rare earth elements (REE) extraction and evaluation. Through the Sandy Mitchell programme in various periods of 2023 and 2025, Ark Mines utilized a combination of drilling and sampling techniques to evaluate the mineral resource. The processing tests at Currumbin Minerals and IHC Robbins involved wet gravity and electrostatic separation, achieving notable levels of REE concentration, particularly in the production of a monazite concentrate with 52.2% TREO. The test results highlight potential commercial viability with product streams achieving high grades of REE, and processes like triboelectrostatic separation have shown efficiency in handling fine fractions. The document also discusses the conversion of assay data for REEs, zirconium, hafnium, and titanium to their stoichiometric oxides and potential economic minerals identified include monazite, xenotime, zircon, rutile, and ilmenite.
