The test work was the result of an academic study conducted by the School of Applied Sciences, University of Brighton, UK, to understand the minerology of a representative sample from the Reverse Circulation drilling conducted at the Talairyk deposit by East Star in October 2022.\n \nHighlights of the study:\n \n· The mineralogy and total rare earth elements (TREE) concentrations of the Talairyk samples are comparable to ion adsorption deposits globally with a kaolinite-dominated mineralogy and 815-5,185 ppm TREE\n· Single phase leach results from ammonium sulphate have lower recovery with peak results (pH4) demonstrating ~7.5% recovery of NdPr meaning the leachability of the tested samples is not representative of proven ion adsorption clay deposits\n· Peak results from sulphuric acid single phase leach demonstrated 26%-34% NdPr, 14-18% Dy and 18-21% Tb recovery suggesting further test work is required to assess if there is a potential route to commercial extraction\n· Sequential leach tests resulted in an average total recovery of 90.6% of Neodymium and Praseodymium (NdPr), 90.7% Terbium (Tb) and 73.8% Dysprosium (Dy) demonstrating that the majority of REEs are liberated from leach resistant silicate materials\n· The highest...
