This milestone confirms the project's viability to produce industry-standard cesium chemicals and significantly de-risks the asset, positioning the company as a potential near-term producer of critical minerals. Reasoning: The final metallurgical test work successfully demonstrated high cesium extraction \(97%\) and the production of high-purity \(99.8% and 99.6%\) technical grade cesium chemicals, meeting industry standards and significantly de-risking the Case Lake project. - Positive factor: High Recovery - Positive factor: Pilot Scale Complete - Positive factor: Free Milling - Positive factor: QP/CP Signed Facts used in scoring: 156 ## Classification and evidence **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).
