Cadence Minerals announced the announcement by European Metals Holdings Limited detailing the results of the Lithium Chemical Plant (LCP) pilot programme at Cinovec. The results confirm the robustness of the LCP process flowsheet and provide a strong foundation for the execution of the Cinovec Project. Highlights: Pilot programme has confirmed industrial viability of the LCP process flows sheet.

Exceptionally clean battery grade lithium carbonate (>99.9%) produced with single-stage purification (bicarbonation) of crude lithium carbonate. Pilot programme crude lithium carbonate confirmed at 99.7% purity, greater than battery grade (99.5%) in the carbonate precipitation step without any additional processing. Work to produce battery grade lithium hydroxide monohydrate is underway.

The pilot programme processed ore fully-representative in all respects of the run-of-mine for the first seven years of mining planned at Cinovec, including average grade and expected rock-type mix from the bulk mining. Next Stage of Development of Cinovec: The DFS for battery-grade Lithium Carbonate remains on-track for completion in fourth quarter of 2023. Subject to confirmation of the pilot programme work for battery grade Lithium Hydroxide, a decision on the battery grade end-product (carbonate vs hydroxide) for the Cinovec Project is expected to be made in early 2024.

This will in turn lead to design engineering that will enable the Project to move to production in the shortest possible time frame, and includes engagement with long lead equipment OEMs to ensure that the timeline is expedited.
