The playbook — gold · September 17, 2026
Cartier's Cadillac PEA lands a billion-dollar number, on paper
An updated study pegs the Val-d'Or gold project at a C$1.0B after-tax NPV — if gold holds US$3,600. The stock ran 40% while the sector crawled.
On September 17, 2026, Cartier Resources put a fresh number on its Cadillac gold project near Val-d’Or, Quebec: an after-tax NPV5% of C$1.0 billion and an after-tax internal rate of return of 26.6%. That comes from a Preliminary Economic Assessment — an early-stage study that sketches what a mine might earn, not a decision to build one. The stock had a reaction to match. Over three months ECR.V climbed 40% to C$0.35, a slow staircase from around C$0.25, while junior gold miners as a group rose 11.1% and gold itself barely moved at 0.6%. That is roughly four times the peer index — company-specific, not the tide lifting all boats.
Here is the machinery behind the billion. The whole picture leans on a gold price assumption of US$3,600 an ounce. Drop that to US$3,000 and the after-tax NPV nearly halves, to C$497M, with the IRR sliding to 16.4%. The resource itself is modest grade — about 2.28 grams per tonne mined, meaning each tonne of rock carries a bit under a tenth of an ounce — and it comes out of the ground the expensive way, underground at C$95.1 per tonne, pushing all-in sustaining cost to US$2,137 an ounce. This is an old mining address with real bones: the Chimo Mine has existing infrastructure and sits on the Cadillac Fault, one of Quebec’s most productive gold structures. The team is led by founder Philippe Cloutier, a 35-year Abitibi geologist who helped discover the Bell-Allard South copper-zinc mine — though Cartier itself has never built a mine, and the study was prepared by independent QPs across four consulting firms — Evomine Consulting (mine design and economics), PLR Resources (resource estimate), Soutex (metallurgy), and Geodoz Conseil (environmental).
Now the honesty. This is an economic study, not a drill release, so there are no intercepts to weigh — no true widths, no gram-metres. Roughly 76% of the contained ounces, about 2.42 million, sit in the Inferred category, which the release itself flags as insufficiently drilled; the economics depend materially on ounces that are not yet confidence-classified. A PEA declares no reserves and demonstrates no economic viability by definition. Metallurgical recovery of 95% rests on just six variability samples from three zones — a thin dataset for a mine design. Cartier’s recent financings have been small next to the C$275.8M initial capital, with Agnico Eagle now at roughly 32%. Watch for the full NI 43-101 technical report, due within 45 days, and for the ~35,000 metres of 2025-26 drilling that has not yet entered the resource model — upside that could move the numbers in either direction.
