Thin Fernie and Exshaw phosphorite beds in the Eastern Slopes while Alberta imports 2 Mt of rock a year.
Exshaw Formation phosphorite in the Crowsnest Pass reaches 25 % P2O5 but in seams under 50 cm (less than 10 Mt in situ), and the Fernie Formation holds about 260 Mt of low-grade rock in Alberta. Most lies in restricted Eastern Slopes zones. Alberta's fertilizer plants import roughly 2 Mt/yr of phosphate rock, and REE enrichment around 750 ppm does not change the economics.
Fernie / Exshaw phosphorite (Crowsnest–Banff)Permissive only
Thin Jurassic–Mississippian phosphorite beds in the Front Ranges · 0–100 m
Fernie Formation basal phosphorite 0.3–2 m thick, 10–25 % P2O5
Too thin and structurally complex for economic mining today; REE-enriched
