Century Lithium Corp. (Vancouver, B.C., Canada) has announced its plans to develop a commercial-scale chlor-alkali plant (CA Plant). The CA Plant is intended to support the critical and strategic minerals supply chain in the Western United States and the Company’s 100%-owned Angel Island Lithium Project in Esmeralda County, Nevada, USA, currently in the permitting phase.
“In the course of our work on Angel Island, Century Lithium identified chlor-alkali products as a fundamental component of the critical minerals supply chain,” said Bill Willoughby, President and CEO of Century Lithium. “We also recognized a regional opportunity in the Western U.S. for a plant producing these products. The proposed CA Plant has the potential to generate revenue on its own, train an operating team, and reduce future reagent supply risk to Angel Island. Century Lithium has evaluated a number of potential sites for the CA Plant in Nevada and Utah that could meet its criteria for proximity to infrastructure and resources and expects to finalize a selection shortly. The Company has obtained non-binding offtake interest for production from the CA Plant from a number of companies and is actively pursuing project-level financing.”
Chlor-alkali products are essential inputs across the critical minerals supply chain, supporting lithium and battery-materials processing, rare earth element separation, and precious and specialty metals production, in addition to broader industrial and household uses. The proposed CA Plant would produce chlorine, hydrochloric acid, and sodium hydroxide from sodium chloride, water, and electricity, at a target commercial production rate of 300 short tons per day (st/d) of chlorine, with provision to double capacity to 600 st/d depending on regional demand and the supply needs of Angel Island. Century Lithium has entered into eight non-binding Memoranda of Understanding (MOU) with third parties for offtake arrangements that could collectively account for the full initial production of the proposed CA Plant. Candidate sites in Nevada and Utah were evaluated against feedstock, power, rail access, market proximity, land tenure, and permitting criteria. The proposed CA Plant would use modern, proven technology in a location favorable for infrastructure development. Site due diligence is underway; the next step will be securing project-level financing to fund property acquisition, front-end engineering and design (FEED), and permitting of the selected site.
The Company is in the process of selecting the preferred site for the CA Plant from a number of candidate sites, which included a combination of private industrial land, state land, and federally controlled land available under lease. The site selection process has considered internal engineering and economic work and studies addressing equipment selection, power, water, and sodium chloride supply, CA product handling, and comparative site economics.
The Feasibility Study for Angel Island (Updated NI 43-101 Technical Report on the Feasibility of the Clayton Valley Lithium Project, Esmeralda County, Nevada, USA, January 3, 2026) includes an on-site chlor-alkali plant as the base case for the Project. The capital and operating estimates disclosed in the Feasibility Study are unchanged by this announcement. The proposed CA Plant in this announcement does not replace that facility, and none of its cost is added to Angel Island.
The economics of the proposed CA Plant are based solely on internal study and the assumption of commercial sales of all chlor-alkali products to third-party customers. No revenue, cost saving, or capital credit associated with Angel Island is included in them, and the CA Plant is intended to be financed at the project level.
The supply of reagents from the proposed CA Plant to Angel Island would depend on the economics of transportation, still to be determined. Century Lithium (Vancouver, British Columbia, Canada) views the proposed CA Plant as a self-funding first step toward Angel Island rather than a change in the Company’s lithium strategy.
Century Lithium has entered into eight non-binding MOUs with companies in various industrial and chemical sectors in the Western U.S. to supply them with chlorine, hydrochloric acid, and sodium hydroxide produced by the proposed CA Plant. The Company is also in discussions with other prospective purchasers of these products.
Century Lithium intends to finance the proposed CA Plant through non-dilutive financing at the project level. The capital structure under evaluation contemplates a combination of vendor financing associated with site acquisition, institutional preferred equity, prepayments and similar support from offtake counterparties, and non-dilutive United States government programs that may be available to domestic critical minerals and industrial capacity. The Company has engaged financial advisors and has commenced consultations with United States government financing agencies. Land acquisition and front-end engineering are expected to be funded first, with construction financing arranged following completion of FEED and definitive offtake agreements.
Century Lithium’s objective in structuring the proposed CA Plant separately is to fund it with capital appropriate to an industrial chemical asset with anticipated offtake, and to limit dilution to shareholders of Century Lithium. No financing has been secured at this time, and no definitive agreements have been entered into, and there is no assurance that financing will be available on acceptable terms or at all.
Due diligence is underway and includes property negotiations, project-level funding, and investigation of power supply terms with the serving utility, salt feedstock and transportation, water rights, land tenure and title, environmental condition, and the permitting pathway. Once the preferred site is selected and secured, the Company intends to advance the preferred site to FEED with a qualified engineering, procurement, and construction contractor and to commence permitting, while continuing discussions with prospective commercial counterparties and sources of project financing. Long-lead electrical equipment is a recognized schedule constraint for United States chlor-alkali projects, and the Company is evaluating equipment sourcing in parallel with site selection.
