CENTURY LITHIUM PRODUCES LITHIUM HYDROXIDE AT DEMONSTRATION PLANT IN NEVADA

The October 20, 2025 news release announces that Century Lithium has successfully produced high-purity (+99.5%) lithium hydroxide samples for the first time at its Demonstration Plant in Nevada. This was achieved using lithium carbonate derived from the company's Angel Island project through its proprietary alkaline leach and Direct Lithium Extraction (DLE) process. The company noted that until this point, its focus had been on producing lithium carbonate, and this achievement demonstrates the potential to supply another major lithium product to the domestic market.

This news is a positive technical milestone, but its immediate impact is likely limited.

Positives: * Product Diversification: Demonstrates the versatility of the company's process and the potential to produce lithium hydroxide (LiOH) in addition to lithium carbonate (Li2CO3). This could broaden their future customer base, as different battery chemistries require different lithium products. * Technical De-risking: Successfully producing a new, high-purity end-product at the demonstration plant adds credibility to the technical team and the proprietary process.

Negatives/Concerns: * Does Not Address Core Risk: The primary obstacle for Century Lithium is not its ability to produce small quantities of high-purity lithium products, but its ability to finance the multi-billion-dollar CAPEX required to build the full-scale Angel Island mine, as outlined in the April 2024 Feasibility Study (FS). This news does nothing to alleviate that concern. * Potential Distraction: The announcement states that efforts were focused on carbonate "up until this point." While versatility is good, this pivot could be seen as a distraction from the main goal of finalizing the engineering and permitting for the carbonate plant defined in the FS. It raises questions about potential changes to the flowsheet, which could impact CAPEX/OPEX and delay the updated feasibility study. * Context of Recent Financing: The company struggled to raise a relatively small $5 million over the summer of 2025, having to significantly sweeten the terms (extending warrants to 5 years) to close a total of $4.73 million. This demonstrates a very difficult financing environment for the company. A technical update, while positive, is unlikely to move the needle for the large-scale strategic or government funding they require.

Overall, the production of lithium hydroxide is an incremental, positive step. However, it is routine in the context of a pilot plant's purpose, which is to test and optimize processes. It does not materially change the company's precarious financial situation or the monumental funding challenge ahead.

Century Lithium Corp. is an advanced-stage lithium development company focused on its 100%-owned Angel Island Lithium Project (formerly Clayton Valley) in Nevada, USA. The project hosts one of the largest sedimentary lithium deposits in the United States.

The company completed a Feasibility Study in April 2024, outlining a 40-year mine life with phased production to ultimately produce 39,000 tonnes per year of lithium carbonate. The project uses a proprietary, patent-pending process involving chloride leaching, Direct Lithium Extraction (DLE), and a chlor-alkali plant to produce its own reagents on-site and a saleable sodium hydroxide byproduct. The company has been operating a demonstration-scale plant in Amargosa Valley, Nevada, for over two years to de-risk this technology.
