CENTURY LITHIUM RECONFIRMS PRODUCTION OF
BATTERY GRADE PURITY LITHIUM CARBONATE
AND PROVIDES UPDATE ON FEASIBILITY STUDY
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.
