CENTURY LITHIUM ADVANCES DEMONSTRATION PLANT RELOCATION TO TONOPAH AND PROVIDES REAGENT COST STRUCTURE UPDATE
Rhea-AI Summary
Century Lithium (OTCQX: CYDVF) is relocating its Demonstration Plant to Tonopah, Nevada, with commissioning targeted for H2 2026. The company emphasizes a patent‑pending chlor‑alkali process that uses NaCl and electricity instead of sulfuric acid, and a 2026 Feasibility Study reports an after‑tax NPV of US$4.01 billion and average operating costs of US$4,389/t lithium carbonate.
The Demonstration Plant will run structured metallurgical tests on claystone zones 1 and 2, pursue a Nevada water permit, and showcase salt‑based extraction to stakeholders and funding partners.

Demonstration Plant Commissioning Targeted for H2 2026; Company's Chlor-Alkali Process Uses Salt-Based Reagents with No Direct Exposure to Rising Global Sulfur and Sulfuric Acid Prices
"During the last five years, Century Lithium developed an integrated process flowsheet that successfully produced battery-grade lithium carbonate from Angel Island claystone. The patent-pending process uses salt, rather than sulfur-derived reagents, which distinguishes Angel Island from spodumene and most sedimentary lithium projects globally," said Bill Willoughby, President and CEO of Century Lithium. "Moving the Demonstration Plant to

Upon completion, the Company plans to conduct structured metallurgical testing per the recommendations of the 2026 Feasibility Study (described below), including full test runs on claystone zones 1 and 2. Bench-scale testing reported in the Feasibility Study indicates the deeper claystone performs as well as, or better than, the bulk samples of surface material used in earlier runs. The Company also plans to evaluate improvements to leaching, direct lithium extraction ("DLE"), and lithium carbonate and hydroxide production.
The Demonstration Plant will also serve as a showcase of salt-based lithium extraction for government agencies, community stakeholders, and potential funding partners. The Company is pursuing federal critical-minerals funding opportunities, including evaluation of the potential recovery of additional critical elements from Angel Island leach solutions as identified in the Feasibility Study.
Century Lithium's Chlor-Alkali Process: Salt as the Foundation
Angel Island is built around a patent-pending chlor-alkali process in which hydrochloric acid ("HCl") and sodium hydroxide ("NaOH") are generated on-site from sodium chloride ("NaCl") and electricity. HCl leaches lithium from Angel Island claystone; NaOH provides pH control throughout leaching, filtration, and DLE. Both reagents are continuously regenerated as co-products of the electrolytic cells, closing the loop and eliminating reliance on external acid supply chains.
The process does not use sulfuric acid and produces no sulfate by-products. The primary inputs are NaCl and electricity which are stable, domestically available, and structurally uncorrelated to sulfur markets. As set out in the 2026 Feasibility Study, NaOH surplus to process requirements, which is expected to be significant, available for sale as an economic by-product.
Global Sulfur Market Conditions: Why the Process Design Matters Now
Global sulfur markets are experiencing an extraordinary dislocation with direct consequences for agriculture and basic industries including metals.
2026 Feasibility Study
The 2026 Feasibility Study on Angel Island, prepared by Mineral Property Development, LLC ("MPDI"), Global Resource Engineering, Ltd. ("GRE") and SRK Incorporated ("SRK") in accordance with National Instrument 43-101 (NI 43-101), confirms that the chlor-alkali process's structural insulation from these supply chain forces underpins strong project economics with an after-tax NPV of
