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 lithium

carbonate over a 40-year mine life.
