Record Ridge magnesium project injunction: permitting and ESG lens for mine planners
Reviewed by Tom Sullivan

30 Second Briefing
A temporary injunction from British Columbia’s Court of Appeal is holding up West High Yield Resources’ Record Ridge open-pit magnesium project near the US border until a 5 May judicial review of its environmental permitting, including whether the US-based Sinixt Confederacy must be formally consulted. The 43-million-tonne measured and indicated resource grading 24.6% Mg, with a proposed 172-year mine life and C$250 million capex, had been slated for construction this quarter and first production in Q1 2027. Local and Indigenous opponents are challenging the decision that the sub-threshold project did not require a full provincial environmental assessment, citing asbestos-bearing rock, Columbia River-linked waterways and sensitive ecosystems.
Technical Brief
- BC’s Environmental Assessment Office exempted Record Ridge from full assessment because planned output sits below statutory thresholds.
- Judicial review on 5 May will scrutinise that exemption decision rather than the underlying resource or mine plan.
- Sinixt Confederacy objections focus on potential impacts to Columbia River–linked waterways and culturally important riparian areas.
- Asbestos-bearing serpentinised host rock is a core concern for opponents, raising questions on waste handling and dust control.
- Record Ridge lies ~5 km north of the US border and ~500 km east of the Port of Vancouver, constraining logistics routes.
- A November 2022 PFS reported after-tax NPV of C$728 million, IRR 118% and 1.5‑year payback.
- West High Yield’s forward sales agreement with Galaxy Trade and Technology targets at least C$30 million annual revenue for first two years.
- Ongoing BC debate on the role of foreign Indigenous nations in permitting could set precedent for other transboundary projects.
Our Take
Record Ridge’s very long notional mine life and relatively modest capex put West High Yield’s magnesium project at the smaller, niche end of the critical minerals spectrum in our mining-projects coverage, which may make permitting risk more material than financing risk.
The offtake-style forward sales agreement with Galaxy Trade and Technology, guaranteeing at least $30 million per year in early revenues, is unusually front-loaded for critical minerals projects in our database and likely underpins the aggressive IRR and payback assumptions in the 2022 PFS.
