The Lemoray occurrence lies north of the Pine Pass Highway near Lemoray.
Phosphate deposits in the Rocky Mountains of northeast British Columbia occur in a sequence of marine strata, ranging in age from Cambrian to Jurassic but only Triassic occurrences appear to have possible economic significance. At Lemoray, a 1 to 2 centimetre phosphorite bed is present in Triassic strata, believed to belong to the Toad Mountain Formation (correlative with the Whistler Member of the Sulphur Mountain Formation south of Pine River). In thin section it is seen to consist of dark brown to black, ovoid pellets in fine-grained dolomite, quartz and clay matrix. Some chert is also present.
