CENTURY LITHIUM ADVANCES DEMONSTRATION PLANT RELOCATION TO TONOPAH AND PROVIDES REAGENT COST STRUCTURE UPDATE

• Century Lithium confirms relocation of its Demonstration Plant from Amargosa Valley to Tonopah, Nevada, with commissioning targeted for H2 2026.
• The company details its patent-pending chlor-alkali process which utilizes salt-based reagents (NaCl) instead of sulfur/sulfuric acid.
• Current market context highlights a surge in global sulfur prices (China spot $950/t, US acid up to $146/t), validating the cost advantage of the NaCl process.
• The 2026 Feasibility Study metrics are reiterated: After-tax NPV of US$4.01 billion and average operating costs of US$4,389/t of lithium carbonate.
• A significant surplus of sodium hydroxide (NaOH) is expected from the process, intended to be sold as an economic by-product.

• The news serves as a validation of the February 2026 Feasibility Study rather than introducing new financial terms or capital commitments.
• By confirming the reagent cost structure against rising sulfur prices, the company reduces execution risk regarding operating expenses (OpEx).
• However, the core economic metrics ($4.01B NPV) were already disclosed in February 2026; this update reinforces existing expectations without materially altering valuation models.
• The Demonstration Plant relocation was previously announced in October 2025 ("begun moving"); this news confirms progress and timelines (H2 2026 commissioning).
• No new strategic investors or off-take agreements are disclosed, leaving the significant capital gap for Phase 1 construction ($997M) unaddressed.

• Company: Century Lithium Corp. (TSX.V: LCE).
• Flagship Project: Angel Island Lithium Project in Esmeralda County, Nevada.
• Project Status: Advanced stage; Feasibility Study completed (Feb 2026), Pilot/Demonstration Plant operating, Permitting progressing (FAST-41 status).
• Technology: Patent-pending chloride-based leaching and Direct Lithium Extraction (DLE) process integrated with chlor-alkali for on-site reagent generation.
• Production Plan: Phase 1 targets ~26,500 tpa lithium carbonate over a 40-year mine life; Phase 2 expansion to higher throughput in Year 5.
