Century Lithium Signs Eight MOUs for Nevada Chlor-Alkali Plant

Century Lithium (TSXV: LCE) said it has entered eight memoranda of understanding to advance a chlor-alkali plant in Nevada, a facility intended to supply reagents to its lithium operation; U.S.-quoted shares under CYDVF traded at 0.17, down 2.78%, as of 17:55 GMT on Sept. 23, 2026.

Century Lithium (TSXV: LCE) has signed eight memoranda of understanding aimed at advancing a chlor-alkali plant in Nevada, a step that moves the company's reagent strategy from flowsheet diagram toward something with counterparties attached.

The announcement, reported by Canadian Mining Journal, is unusual in the junior lithium space for what it is not: it is not an offtake deal, not a financing, and not a resource update. It is infrastructure — specifically, the chemical plant that would feed the acid and caustic soda a chloride-based lithium process consumes in bulk.

What a chlor-alkali plant actually does for a lithium developer

Chlor-alkali is one of the oldest continuous processes in industrial chemistry. Pass an electric current through a salt brine and the sodium chloride splits into three saleable products: chlorine gas, caustic soda (sodium hydroxide) and hydrogen. Combine the chlorine with the hydrogen and you get hydrochloric acid.

That output list maps almost exactly onto the input list of a chloride-leach lithium operation. Hydrochloric acid does the leaching — dissolving lithium out of the host material. Caustic soda does the neutralising and the pH control further down the circuit. A developer that buys both on the open market is exposed to reagent pricing, trucking costs across the Nevada desert, and the availability of industrial chemicals in a region where supply chains are thin.

A developer that makes them on site converts a variable operating cost into a capital cost it controls. That is the economic argument, and it is why the chlor-alkali question sits so close to the centre of the project's economics rather than off to one side as a utility footnote.

The trade-off is equally plain. Chlor-alkali is electricity-intensive — electrolysis is the whole process — so the plant imports a power problem in exchange for solving a chemicals problem. It also adds construction scope and capital to a project that has to be financed before a single tonne of lithium is sold. Eight MOUs suggest the company is trying to distribute that burden across partners rather than carry it alone.

Why eight non-binding agreements still tell you something

A memorandum of understanding commits nobody to anything. It sets out intent, scope and a framework for further negotiation, and a fair share of MOUs signed in the mining sector never convert into contracts. Investors are right to discount them.

But the count matters. One MOU is a conversation. Eight, signed around a single facility, points to a package being assembled — the kind of arrangement that typically spans some combination of engineering, power supply, salt feedstock, product offtake for the chlorine and caustic streams not consumed on site, land or utilities, and potential equity or development partners. Century Lithium has not, in the information available, identified the counterparties or broken down which role each agreement covers, and until it does the market is being asked to price intent rather than obligation.

The reason a chlor-alkali plant can support that many counterparties at once is that it produces more than the lithium circuit needs. Chlorine and caustic soda have end markets of their own — water treatment, pulp, alumina, general industrial chemistry. A lithium developer that builds one is, on paper, also standing up a second business with its own revenue line. Whether Century Lithium intends to pursue that or simply sized the plant to internal demand is the detail that will determine how much of the capital is genuinely incremental.

Nevada as the place this gets built

Nevada is the natural home for this. The state holds the only producing lithium operation in the United States, its Clayton Valley basin has drawn a generation of exploration capital, and the permitting and industrial-chemicals context is more accommodating than most American jurisdictions. Century Lithium's Nevada lithium asset — the Angel Island project in Clayton Valley — is the reason the reagent question arises in the first place; a chloride-leach flowsheet that has to import acid across state lines is a materially different proposition from one that manufactures it at the gate.

The wider policy backdrop is also pulling in this direction. Domestic processing capacity, not just domestic ore, has become the stated priority across U.S. critical-minerals policy, and a chemicals plant attached to a lithium project is exactly the kind of midstream asset that framing favours. That does not make the financing easier, but it widens the pool of parties with a reason to sign something.

How the shares are trading

Century Lithium's U.S.-quoted shares, under the symbol CYDVF, changed hands at 0.17 as of 17:55 GMT on Sept. 23, 2026, down 2.78% from the prior close of 0.18. The stock traded in a band of 0.16 to 0.18 through the session — a range that, on a sub-penny-increment quote, represents the ordinary spread noise of a thinly traded small-cap rather than a verdict on the announcement.

It was a soft tape generally. The S&P 500 proxy SPY was at $768.53, off 0.63% on the day; the Nasdaq 100 tracker QQQ was at $740.83, down 0.89%; and the Dow 30 fund DIA sat at $515.23, lower by 0.53%. A developer-stage miner declining fractionally into a broadly red market has not been singled out.

What converts intent into value

Three things would move this from announcement to substance. First, names: which parties signed, and for what. An engineering firm and a power provider carry different weight than a letter of general interest. Second, conversion: MOUs that become definitive agreements with dates and obligations attached. Third, capital: a chlor-alkali plant is a real build, and the question of who funds it — Century Lithium's balance sheet, a partner, a government programme, or some blend — has not been answered by this news.

Until then, the sensible read is that the company has broadened the set of people with a stake in the Nevada plant getting built, which is a prerequisite for financing rather than a substitute for it. For a junior developer, assembling that group of counterparties before asking the market for construction money is the correct order of operations. The eight signatures are the beginning of that process, not its conclusion.

Frequently asked questions

What is a chlor-alkali plant?

It is an industrial facility that runs electricity through salt brine to split sodium chloride into chlorine gas, caustic soda and hydrogen. Combining the chlorine and hydrogen yields hydrochloric acid. All three outputs are core industrial chemicals, and two of them — acid and caustic soda — are heavily consumed by chloride-based lithium processing circuits.

Why does Century Lithium want one in Nevada?

A chloride-leach lithium flowsheet uses hydrochloric acid to dissolve lithium and caustic soda to control pH downstream. Buying both on the open market exposes the project to reagent prices and long desert trucking routes. Producing them on site converts a recurring operating cost into a capital cost the company controls, which is the central economic argument for the plant.

Are the eight MOUs binding commitments?

No. A memorandum of understanding records intent and sets a framework for further negotiation; it does not oblige either party to complete a transaction. Many MOUs in the mining sector never convert into definitive agreements. Their value here is as a signal that Century Lithium is assembling a group of counterparties around the project rather than proceeding alone.

Who are the counterparties to the agreements?

Century Lithium has not identified them in the information available, nor has it broken out which role each of the eight agreements covers. Facilities of this type typically involve some mix of engineering contractors, power suppliers, feedstock providers, chemical offtakers and potential development or equity partners, but that breakdown has not been disclosed.

How did the shares react?

Century Lithium's U.S.-quoted stock under CYDVF traded at 0.17 as of 17:55 GMT on Sept. 23, 2026, down 2.78% from a prior close of 0.18, within a session range of 0.16 to 0.18. Broad market benchmarks were also lower that day, with SPY off 0.63% and QQQ down 0.89%.

What should investors watch next?

Three markers determine whether this news carries value: disclosure of the counterparties and their specific roles, conversion of the memoranda into definitive agreements with dated obligations, and a funding plan for construction. A chlor-alkali plant is a capital-intensive build, and the financing question has not been answered by the announcement itself.
