The Wheaton Jade occurrence is located about 63 kilometres east-southeast of the community of Dease Lake.

The showing is underlain by upper Mississippian to Permian ultramafic rocks of the Cache Creek Complex. These rocks consist of peridotite, dunite and pyroxenite which are generally serpentinized.

The ultramafic rocks locally include pods of nephrite jade, one of which is plotted on Geological Survey of Canada Open File map 2779, about 750 metres east of Wheaton Creek at a point 3 kilometres upstream from its mouth. The characteristics of these pods are not documented. See placer jade occurrence Wheaton Creek Jade (104I 085) located 2.7 kilometres north for related details.
