NEWS RELEASE

CENTURY LITHIUM PROVIDES UPDATE ON ANGEL ISLAND AND

LITHIUM EXTRACTION FACILITY

February 4, 2025 – Vancouver, Canada – Century Lithium Corp. (TSXV: LCE) (OTCQX: CYDVF) (Frankfurt:

C1Z) (“Century Lithium” or “the Company”) is pleased to provide an update on its wholly owned Angel

Island project near Silver Peak, Nevada, USA and associated Lithium Extraction Facility (“Pilot Plant”) in

Amargosa Valley Nevada. The Company has completed the successful implementation of process

improvements at its Pilot Plant. These changes were developed in collaboration with Amalgamated

Research, LLC (“ARi”) of Twin Falls, Idaho, a research and development company specializing in industrial

implementation of process technologies. Century Lithium is now shifting the focus at its Pilot Plant from

research and development to demonstration.

“The initial results from ARi are very encouraging, indicating greater efficiency can be achieved that could

result in positive reductions in the estimated capital and operating costs at Angel Island,” said Century

Lithium President and CEO, Bill Willoughby. “Century Lithium remains committed to delivering value to our

shareholders through Angel Island, one of the few advanced lithium projects in the United States. We are

optimistic about the long-term fundamentals of the lithium market and the strategic importance of Angel

Island to the future mineral supply in the United States.”

Project Update

The processing testing program (“Program”) implemented ARi’s proprietary adsorption-based technology

for Direct Lithium Extraction (“DLE”) and was accomplished in conjunction with ARi’s Twin Falls testing

facilities and Century Lithium’s Pilot Plant. The results of the Program are positive and further validate the

efficiency of Century Lithium’s extraction technology. The Program augmented Century Lithium’s DLE

system with the addition of ARi equipment and expertise. Early results indicate Century Lithium can

eliminate the recycle loops within its DLE and lithium carbonate areas, while increasing eluate grades. The

Company believes this will result in a substantial reduction in estimated capital and operating costs at Angel

Island.

The decision to shift the focus at the Pilot Plant to demonstration mode is two-fold; it will allow the

Company to focus on providing dedicated testing to prospective strategic partners or potential end-users

and reduce the ongoing operating costs of the Pilot Plant. Current Pilot Plant operations will continue to

convert a backlog of lithium solutions, which were made prior to the commissioning of the on-site lithium

carbonate process at the Pilot Plant, into battery-grade lithium carbonate.

Moving Forward

The Company recently announced a non-binding Memorandum of Understanding (“MOU”) with Orica

Specialty Mining Chemicals (see news release). The non-binding MOU outlines the intent of Century

Lithium and Orica to formalize a multiyear offtake agreement for Orica to purchase sodium hydroxide from

Angel Island. The favorable outlook for the sodium hydroxide by-product contributes significantly to

Century Lithium’s low-cost lithium carbonate production model.

Ongoing engineering is focused on mining, and the leaching, filtration, DLE, and lithium carbonate

processing areas. The Company continues to compile all data generated at the Pilot Plant. The data will be

used in engineering models and to run analytical tests on full-scale construction designs focused on further

reducing the estimated capital and operating costs for producing lithium carbonate at Angel Island.

Century Lithium remains focused on seeking strategic partnerships with potential end-users and market

participants interested in securing a domestic supply of battery-grade lithium carbonate. The Company

continues to move forward with permitting work to ensure that our future operations at Angel Island will

align with both regulatory requirements and Century Lithium’s environmental and social stewardship

goals.

ABOUT CENTURY LITHIUM CORP.

Century Lithium Corp. is an advanced stage lithium company, focused on developing its wholly owned

Angel Island project in Esmeralda County, Nevada, which hosts one of the largest sedimentary lithium

deposits in the United States. The Company has utilized its patent-pending process for chloride leaching

combined with direct lithium extraction to make high purity lithium carbonate product samples from Angel

Island lithium-bearing claystone on-site at its Pilot Plant in Amargosa Valley, Nevada.

Angel Island is one of the few advanced lithium projects in development in the United States to provide an

end-to-end process to produce battery quality lithium carbonate for the growing electric vehicle and

battery storage market. Angel Island is currently in the permitting stage for a three-phase feasibility-level

production plan expected to yield an average of 34,000 tonnes per year of lithium carbonate over a 40-

year mine-life.

Century Lithium trades on both the TSX Venture Exchange under the symbol “LCE” and the OTCQX under

the symbol “CYDVF”; and on the Frankfurt Stock Exchange under the symbol “C1Z”.
