Phosphate occurs 15 kilometres southeast of Sparwood in the Crowsnest Pass area, 2.5 kilometres north of the pumping station on Highway 3.

Pelletal phosphorite is contained in two beds separated by phosphatic shale at the base of the Jurassic Fernie Group. The top of the phosphate horizon is marked by a thin yellowish weathering cherty limestone bed. The phosphate generally strikes north with shallow to moderate dips to the west. Thrust faulting complicates the distribution of the phosphate, causing the repetition of beds at some localities while causing the same beds to disappear in other locations. The horizon is locally structurally thickened to 4.8 metres. Individual phosphorite beds are 0.7 to 1.0 metre thick and contain 25.1 to 27.0 per cent P2O5 (Open File 1987-16, page 94, samples SBB86-4A to E). A sample analyzed by X-ray fluorescence contained 5.34 per cent SiO2, 1.11 per cent Al2O3, 0.53 per cent Fe2O3, 0.40 per cent MgO, 47.72 per cent CaO, 0.34 per cent Na2O, 0.15 per cent K2O, 0.07 per cent TiO2, 0.01 per cent MnO, 29.81 per cent P2O5 and 1.45 per cent sulphur (Fieldwork 1989, page 490, sample VM89-3).

The Crow deposit has been explored periodically by Cominco Ltd. between the 1930's and the mid-1970's. The company shipped an 1800 tonne bulk sample to Trail in 1931 and completed 600 metres of underground development work. Formosa Resources Corporation sampled near the Crow adit in 1989 while assessing the northern extension of the phosphate horizon.
