A small quarry 90 metres northeast of Stuart Lake, 6.3 kilometres northwest of Fort St. James, exposes medium grey, fine grained, well fractured limestone with scattered crinoid remains. The deposit lies on the southwest margin of a 200 kilometre long belt of limestone with minor argillite, chert and greenstone (andesite) of the Mississippian to Triassic Cache Creek Group that extends north- westward along the northeast shore of Stuart Lake.

A sample composed of chips taken at 0.6 metre intervals across the 18.3 metre long quarry face contained 53.75% CaO, 0.22% MgO, 3.30% insolubles, 0.14% R2O3, 0.08% Fe2O3, 0.05% MnO, 0.01% P2O5, 0.008% sulphur and 42.52% ignition loss (Annual Report 1968, p. 310).
