CENTURY LITHIUM REPORTS LITHIUM METAL FROM ANGEL ISLAND DEMONSTRATED IN BATTERY CELLS UNDER U.S. ARMY SBIR PROGRAM

Lithium carbonate produced from Century Lithium Corp.'s 100-per-cent-owned Angel Island lithium project in Nevada, United States, was successfully converted into lithium metal using Alpha-En Corp.'s proprietary extraction and electrodeposition process and incorporated into cylindrical cells manufactured by EaglePicher Technologies. This work was supported by funding from the U.S. Army Small Business Innovation Research (Army SBIR) program, which aims to accelerate the development of innovative technologies critical to national defence.

"Alpha-En has done outstanding work converting lithium carbonate from Angel Island into high-purity lithium metal, which was then incorporated by EaglePicher in cells tested under the U.S. Army SBIR program," said Dr. Bill Willoughby, president and chief executive officer of Century Lithium. "The results from this first phase program are important for Century Lithium and further highlight Angel Island as a quality domestic source of lithium."

The lithium metal anodes produced from Angel Island lithium carbonate by Alpha-En met EaglePicher's performance specifications and were integrated into EaglePicher's cylindrical cells for testing. Initial discharge results demonstrated higher operating voltages and improved power performance compared to the control cells, key attributes for demanding defence applications which require lightweight, high-energy and high-power battery systems.

"This Army SBIR-supported effort demonstrates that high performance lithium metal anodes can be manufactured directly from U.S.-sourced lithium resources," said Landon Oakes, chief technology officer of Alpha-En. "By integrating domestic raw materials with our membrane extraction and electrodeposition platform, we are establishing a secure, vertically integrated pathway for next-generation battery anodes that reduces reliance on foreign supply chains."

This successful demonstration represents a significant step toward strengthening the domestic defense battery supply chain. By connecting U.S.-based lithium resources, advanced lithium metal manufacturing and domestic cell fabrication, the collaboration supports the U.S. Army's objective of securing critical mineral independence while advancing high performance battery technologies for future defence systems.

About Century Lithium Corp.

Century Lithium is an advanced-stage lithium development company focused on its 100-per-cent-owned Angel Island lithium project in Esmeralda county, Nevada. Angel Island hosts one of the largest known sedimentary lithium deposits in the United States and is designed with an integrated, end-to-end process for the on-site production of battery-grade lithium carbonate to support the electric vehicle and battery storage markets.

The company has developed a patent-pending process that incorporates hydrochloric acid leaching combined with direct lithium extraction to produce battery-grade lithium carbonate. As part of the integrated chlor-alkali process, Angel Island is designed to produce sodium hydroxide as a co-product, with planned surplus sales expected to lower operating costs, reduce reliance on externally sourced reagents and minimize environmental impacts.

Century Lithium is currently advancing Angel Island through the permitting process.

Century Lithium trades on the TSX Venture Exchange under the symbol LCE, the OTCQX under the symbol CYDVF and on the Frankfurt Stock Exchange under the symbol C1Z.
