CENTURY LITHIUM PRODUCES LITHIUM HYDROXIDE AT DEMONSTRATION PLANT IN NEVADA

Rhea-AI Summary

Century Lithium (OTCQX: CYDVF, TSXV: LCE) announced on October 20, 2025 that its Demonstration Plant in Amargosa Valley, Nevada produced lithium hydroxide for the first time from lithium carbonate derived from the company's 100%‑owned Angel Island lithium claystone project.

The company reported on‑site batch conversion using conventional liming with calcium hydroxide to make high‑purity +99.5% lithium hydroxide, using its patent‑pending alkaline leach and DLE process. Century Lithium said it is also pursuing a direct lithium conversion route to bypass the carbonate intermediate and reduce energy and operating costs.

Positive

• First lithium hydroxide produced at Demonstration Plant (Oct 20, 2025)
• Product purity reported at +99.5% lithium hydroxide
• Feedstock sourced from 100%‑owned Angel Island claystone project

Negative

• Production reported at a Demonstration Plant in batch mode, not commercial scale
• Current route uses lithium carbonate intermediate, adding a conversion step and energy use

VANCOUVER, BC, Oct. 20, 2025 /PRNewswire/ - 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.

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".
