Release – Century Lithium Reconfirms Production Of Battery Grade Purity Lithium Carbonate And Provides Update On Feasibility Study

Research News and Market Data on CYDVF

May 25, 2023 – Vancouver, Canada – Century Lithium Corp. (TSXV: LCE) (OTCQX: CYDVF) (Frankfurt: C1Z) (Century Lithium or the Company) is pleased to report it has repeated the production of a high-purity lithium carbonate (Li2CO3) grading 99.87% with lithium-bearing claystone from the Company’s 100%-owned Clayton Valley Lithium Project (Project) in Nevada, USA. Several kilograms of the high purity Li2CO3were made from the intermediate lithium solutions generated in January at the Company’s Lithium Extraction Facility (Pilot Plant) in Amargosa Valley, Nevada. Following leaching and direct lithium extraction (DLE) at the Pilot Plant, solutions were shipped to Saltworks Technologies Inc. (Saltworks) where the final processing was completed.

“These results are in line with those we reported in September 2022, when we achieved a significant milestone in making lithium carbonate grading 99.94%” stated Bill Willoughby, President and CEO of Century Lithium. “The latest results confirm our ability to obtain a high purity lithium product with a low level of impurities from our claystone process.”

Century Lithium has now successfully repeated steps from test mining through to the manufacture of battery-grade Li2CO3. The table below is a comparison of the latest results with those from September 2022. Also shown, are the constituent levels for battery grade lithium carbonate as published by two major producers. The results for the Company’s lithium carbonate material assays were finalized by Saltworks and SGS Canada Inc.

Feasibility Study Update

A Feasibility Study on the Project (Study) began in February 2022, with the engagement of Wood PLC as independent lead author. The Study has progressed well, with contributions from Global Resource Engineers, WSP USA Environment & Infrastructure Inc., and thyssenkrupp nucera, and with the support of Century Lithium’s personnel and consultants.

Major areas of the Study are completed and estimates for capital and operating cost estimates received, including those for the chlor-alkali plant portion of the Project. Wood is in the process of consolidating the estimates and reviewing them with Century, along with evaluating further optimization and opportunities for cost reductions. This optimization work will extend beyond the previously estimated mid-year completion date for the Study. The Company continues to focus on the Study and will provide updates in due course.

At the Pilot Plant, the collaboration of Century Lithium and Koch Technology Solutions (KTS) is underway testing the KTS Li-Pro™ process for DLE. Century Lithium personnel are working closely with KTS in the testing program, which has now completed its third 7-day cycle of operation. Thus far, the KTS process equipment has operated exceptionally well, using feed solution from the Pilot Plant, and the Company is very pleased with its performance.
