NEWS RELEASE
CENTURY LITHIUM PROVIDES TECHNICAL UPDATE ON ANGEL ISLAND
May 6, 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 100%-owned lithium project,
Angel Island (“Angel Island”) near Silver Peak, Nevada and the associated Lithium Extraction Facility
("Demonstration Plant") in Amargosa Valley, Nevada.
“Century Lithium has continued to advance Angel Island through the Company’s Demonstration Plant,”
said Bill Willoughby, Century Lithium President and CEO. “Our Demonstration Plant allows us to improve
our technology through various avenues of testing, most recently with ARi, where recent results have
exceeded our expectations.”
Advancements to the Demonstration Plant
Century Lithium has successfully completed testing at the Demonstration Plant in collaboration with
Amalgamated Research, LLC (“ARi”) of Twin Falls, Idaho. This testing focused on new developments within
the Direct Lithium Extraction (“DLE”) portion of Century Lithium’s process. These results exceeded
expectations for lithium recovery and eluate grade produced from a primary step in the DLE process. The
Company believes this could result in a substantial reduction in the estimated capital and operating costs
at Angel Island.
Results from DLE Pilot Testing (November 2024–January 2025):
• 328 milligrams per liter (“mg/L”) lithium feed concentration
• 91.6% lithium recovery
• 575 mg/L eluate grade with a low Na:Li ratio of 0.6:1
Additional Technical Progress at the Demonstration Plant
• An increase of lithium in eluate to 12 to 14 grams per liter (“g/L”) lithium concentration using
specialty membranes in the concentration steps following DLE
• Continued operation of the lithium carbonate (“Li2CO3”) circuit, resulting in 99.87% purity in Li2CO3
samples
• Third-party evaluation is underway on Li2CO3 samples for use in producing lithium iron phosphate
(“LFP”) batteries. LFP batteries have a high energy density and long cycle life and are used in solar,
energy storage systems and long-range EV applications
• Testing is underway for thermal pretreatment of Angel Island clay with the potential to
significantly reduce hydrochloric acid use in the leach stage of processing

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 battery-grade lithium carbonate product samples from
Angel Island’s lithium-bearing claystone on-site at its Demonstration 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-grade 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 estimated life-of-mine average of 34,000 tonnes per year of
carbonate over a 40-year mine-life.
