A Swiss Letter of Support Puts US$212.5 Million Beside First Phosphate's Quebec Mine

Swiss Export Risk Insurance, the Swiss government's export credit agency, has put its name beside a phosphate project in Saguenay–Lac-Saint-Jean. First Phosphate Corp. announced on 16 September 2026 that the agency, known as SERV, had issued it a Letter of Support.

The sum named in that letter is approximately US$212.5 million, and it is directed at Swiss machinery, equipment, goods and services for the company's Bégin-Lamarche mine and processing plant. First Phosphate trades as PHOS on the Canadian Securities Exchange and on Nasdaq, as FRSPF on OTCQX, and on the Frankfurt Stock Exchange under the symbol KD0, ISIN CA33611D1033.

An export credit agency is a state insurer that protects lenders and exporters against the risk of not being paid on cross-border sales. It does not lend. It makes someone else's lending less dangerous, so that the lending happens at all. For a company that has never built a mine, having one of them engaged is not a small thing, and it is worth being precise about what the agency has and has not done.

SERV described a structure, not a sum it is handing over

The release sets out the arithmetic in the company's own words. SERV said it is prepared to consider insurance or guarantees in support of a buyer credit financing, based on an assumed eligible Swiss export contract value of US$250 million. Eighty-five per cent of that assumed contract value is roughly US$212.5 million, which is the financed amount SERV could support. Under OECD rules for officially supported export credits, the agency could cover up to 95 per cent of that eligible financed amount. Eligible costs run to 85 per cent of the export contract value, local costs up to 50 per cent of that value, capitalised interest during construction, and the agency's own premium.

A buyer credit is a loan made to the purchaser of goods rather than to the seller, so that the purchaser can pay the seller in cash on delivery. In this arrangement First Phosphate would be the borrower and a bank, not SERV, would be the lender. SERV's role would be to insure that bank against the borrower failing to repay.

Three things therefore have to happen before a dollar moves. First Phosphate has to place an order with Swiss suppliers of about US$250 million. A bank has to agree to extend the buyer credit. And SERV has to finish its due diligence and sign definitive documents, which the company's release states are subject to negotiation. None of the three has happened.

The measure is C$675 million, from a study built on an older deposit model

The number that gives US$212.5 million its meaning is the cost of the thing being financed. First Phosphate published a preliminary economic assessment of Bégin-Lamarche on 4 December 2024 and filed the supporting technical report on 17 January 2025. It put initial capital at C$675 million and sustaining capital over the life of the mine at C$317 million, on a 23-year operation producing 900,000 tonnes a year of phosphate concentrate at 40 per cent P₂O₅ and 380,000 tonnes a year of magnetite. Its after-tax net present value was C$1.590 billion at an 8 per cent discount rate, with an after-tax internal rate of return of 33.0 per cent, using US$350 a tonne for concentrate and an exchange rate of C$1.37 to US$1.

At that study's own exchange rate, US$212.5 million is about C$291 million: some 43 per cent of the initial capital figure. The remaining C$384 million, plus sustaining capital, would have to come from equity, from other debt, or from further public money. First Phosphate's entire market value at the close on 18 September 2026 was about C$419.9 million, on 189.1 million shares at C$2.22, according to exchange data carried by QuoteMedia on a 15-minute delay.

Two qualifications belong here rather than in a footnote. A preliminary economic assessment is the first and least reliable of the three levels of Canadian mine study. It may use inferred resources, which have no demonstrated economic viability, and it does not support a construction decision.

The second qualification is that this study's mine plan rests on a deposit model that has since been replaced. On 26 May 2026 the company reported an updated estimate with an effective date of 1 May 2026, prepared by Antoine Yassa, P.Geo., of P&E Mining Consultants: 198.5 million tonnes of indicated material at 6.00 per cent P₂O₅ and 89.5 million tonnes of inferred at 6.16 per cent, at a 2.5 per cent cut-off. The technical report supporting it was filed on 24 August 2026. Chief executive John Passalacqua has said publicly that the updated estimate opens the way to a feasibility study; none has been published.

Maple's 14 September piece on this company stated that the deposit had no preliminary economic assessment. That was wrong: the December 2024 study exists and the report is filed. What remains accurate is the harder half of the same point. There is no pre-feasibility study and no feasibility study, and the capital number SERV's support is being measured against is nearly two years old and predates the current resource. The same article also put the company's cash at C$20.19 million as at 28 February 2026; the figure carried from the same statements by market data services is C$16.0 million, against liabilities of C$4.36 million, and the lower number is the one used here. It is secondary data and is not verified against the filed statements.

The strongest case that this is the turn

Put at its best, and it deserves to be put at its best, the argument runs like this.

SERV does not write letters into the air. To assume a US$250 million eligible Swiss export contract, somebody has scoped a processing plant in enough engineering detail for Swiss vendors to price it, and the agency has looked at the project well enough to name a figure. That is a specific, priced supply package, not a memorandum of intent.

It also does not arrive alone. In March 2026 Natural Resources Canada committed C$16.7 million to the company under the Global Partnerships Initiative. On 5 August 2026 Ottawa added C$4.84 million in non-repayable contributions through the First and Last Mile Fund: about C$3.07 million toward power transmission and C$1.77 million toward roads, running through 2030. On 27 July 2026 Quebec granted the project "Filon" fast-track status with its Ministry of Natural Resources and Forests. On 10 July 2026 the company closed a placement of C$17,698,290 gross at C$2.00 a share. On 7 August 2026 its depositary receipts moved up to the Nasdaq Global Market. The indicated tonnage at Bégin-Lamarche is several times what it was, and the technical report behind it is filed.

Read together, the case says that the capital stack for a C$675 million project is being assembled in public, piece by piece, by counterparties who conduct their own diligence: two governments, a state export insurer, and a US exchange with listing standards. Very few juniors at this stage have that many disinterested parties on the file. On the evidence of the past six months, the execution here has been better than the share price has reflected, and saying so is not promotion.

Where that case runs out

It runs out at the difference between diligence and commitment.

Every item on that list is either money already spent on studies and infrastructure work, or permission to proceed, or a statement of willingness. The federal contributions are real cash, and they total C$21.5 million against an initial capital cost of C$675 million. The Filon status changes the speed of a permitting process, not its outcome. The Nasdaq uplisting changes where shares trade. And SERV's letter, the largest number in the sequence by an order of magnitude, is conditional on a contract that does not exist, a lender that has not been named, and the agency's own further review.

There is also a structural point that the headline figure obscures. Export credit support is designed to sell the exporter's goods. The eligible amount is defined by Swiss content, not by what the project needs. If the plant as engineered requires less Swiss equipment than assumed, the supported amount falls with it; if it requires more non-Swiss content, that content is outside this facility entirely. And the whole sum, if it is ever drawn, is debt on the balance sheet of a company that has never generated revenue, secured against a project whose economics were last assessed at the weakest study level Canadian rules recognise.

Neither of those observations makes the letter unimportant. They set its place. First Phosphate has moved from arguing that Quebec phosphate should be financed to holding a document from a foreign state agency about how a specific slice of it could be. That is further than it was in August, and it is still an instrument that turns on a feasibility study nobody has seen and a purchase order nobody has signed.

What the next documents would have to contain

The Letter of Support is dated and public. The things that would give it force are not yet either. A signed Swiss supply contract with a stated value would convert the assumption into a base. A named lender and credit terms would establish the cost of the money, which nothing published so far reveals. A feasibility study on the current resource would replace a C$675 million estimate that is now the oldest load-bearing number in the story. A material change report or definitive agreement filed on SEDAR+ would move SERV from prepared-to-consider to bound.

Until those exist, the fairest description of First Phosphate's position is the one its own release supports: an unusual amount of official support for a project that has not yet been engineered to the standard at which anybody lends against it.

Switzerland has said what it would insure. Nobody has yet said what they will build.
