CENTURY LITHIUM PRODUCES LITHIUM HYDROXIDE
AT DEMONSTRATION PLANT IN NEVADA
October 20, 2025 – Vancouver, Canada – Century Lithium Corp. (TSXV: LCE) (OTCQX: CYDVF) (Frankfurt:
C1Z) (“Century Lithium” or “the Company”) is pleased to announce that the Company’s Lithium Extraction
Facility (“Demonstration Plant”) in Amargosa Valley, Nevada, USA, has produced for its first time lithium
hydroxide from lithium carbonate derived from the Company’s 100%-owned Angel Island lithium project,
located near Silver Peak, Nevada.
“The lithium hydroxide samples produced by our team represent another important milestone for the
Company,” said Bill Willoughby, President and CEO of Century Lithium. “Up until this point, Century’s
efforts have focused on making lithium carbonate as the end product for Angel Island. By producing high-
purity lithium hydroxide, we show that Angel Island can supply another major lithium product for the
domestic market.”
The lithium hydroxide samples were produced from lithium carbonate derived from Angel Island’s lithium
claystone deposit and treated at the Demonstration Plant using Century Lithium’s patent-pending alkaline
leach and Direct Lithium Extraction (“DLE”) process. The lithium hydroxide samples were produced on-site
in a batch process using conventional liming conversion with calcium hydroxide to make high-purity,
+99.5% lithium hydroxide.
The Company is also pursuing a direct lithium conversion (“DLC”) process to produce lithium hydroxide
directly from lithium chloride solution. Such a process would thereby bypass lithium carbonate as an
intermediate stage, simplify operations, and reduce energy consumption and operating costs.
With the demand for mobile and stationary energy storage growing, Century Lithium’s project at Angel
Island is strategically positioned as the United States seeks a reliable domestic source of critical materials.
Lithium carbonate is an essential component for LFP batteries, while lithium hydroxide is needed for high-
energy-density NMC/NCA batteries. By demonstrating the potential to produce both, Angel Island stands
out as a potential key contributor to American energy independence and a resilient battery supply chain.

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.
