CENTURY LITHIUM REPORTS LATEST DEVELOPMENTS
AT ANGEL ISLAND LITHIUM PROJECT, NEVADA
November 24, 2025 – Vancouver, Canada – Century Lithium Corp. (TSXV: LCE) (OTCQX: CYDVF) (Frankfurt:
C1Z) (“Century Lithium” or “the Company”) is pleased to provide a progress update on recent
developments at its 100%-owned Angel Island lithium project, in Nevada, USA.
“Century Lithium’s team remains focused on achieving several key steps ahead as we continue to advance
the development of Angel Island” said Bill Willoughby, Century Lithium President & CEO. “The Company is
progressing on multiple fronts. Our team and consultants have completed and submitted all baseline work
in advance of Angel Island’s Plan of Operations. The Company also continues to make progress on an
update to the 2024 Feasibility Study. We believe Angel Island is an asset that will create high-quality US
jobs, support domestic critical-mineral supply chains, and position Century Lithium as an American
domestic producer of battery-grade lithium carbonate.”
Angel Island
Angel Island is one of the largest known sediment-hosted lithium resources in the United States, and is also
located in favorable geologic, geographic and logistical settings. The Company continues to advance an
integrated and end to end development strategy to convert lithium-bearing claystone into a finished
lithium carbonate product. A key component at Angel Island is Century Lithium’s patent-pending chlor-
alkali extraction technology, which converts sodium chloride, either as a solid or brine, into essential
reagents used throughout the process. This closed-loop system promotes sustainability, reduces reliance
on external chemical supplies, and delivers meaningful cost and environmental advantages.
Permitting Progress
All baseline and environmental studies supporting Angel Island are complete and accepted by the US
Bureau of Land Management. The Company is finalizing the Plan of Operations (“PoO”), which will define
the mine layout, process-plant configuration, water-use and water-management systems, waste-rock and
tailings handling, access infrastructure, and environmental-mitigation measures. Submission of the PoO
will begin the federal permitting process under the National Environmental Policy Act. Century Lithium
continues to work to meet the timeline provided on the Federal FAST-41 Dashboard.
Demonstration Plant Relocation
The Demonstration Plant was fully dismantled and has been relocated to the Company’s Tonopah, Nevada
facility. This facility is Century Lithium’s 20-acre site located at the Tonopah Airport, which is home to the
Company’s field office for Angel Island. It was integral for the preparation and handling of the bulk sample
material treated during the pilot plant program at Amargosa Valley. Century Lithium is evaluating options
to further improve the site and its facilities and expand its research and development capabilities.
Feasibility Study Update
An update to the 2024 Feasibility Study on Angel Island is progressing well. Current work includes
optimization of the Angel Island mine plan and associated equipment to improve estimated operating

efficiency, reductions to the land-use footprint and plant-design modifications are underway with the goal
of lowering estimated operating costs. Most significant are the changes in fluid-management, Direct
Lithium Extraction (“DLE”) design, and lithium-carbonate production, all based on the results from years of
development at the Company’s Demonstration Plant. Electrical-infrastructure is planned to connect to NV
Energy’s nearby Greenlink West transmission project, a 525-kV system under construction connecting Las
Vegas, Nevada to the Fort Churchill substation near Yerington, Nevada. The update work remains centered
on producing lithium carbonate as the primary end product, supported by additional revenue from surplus
sodium hydroxide generated through the chlor-alkali process.
ABOUT CENTURY LITHIUM CORP.
Century Lithium Corp. is an advanced-stage lithium company, focused on developing its 100%-owned
lithium project Angel Island 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 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.
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”.
