Jade outcrops at the head of Hell Creek, a northeastern flowing tributary of Bridge River, 28 kilometres west-northwest of Lillooet.

A mass of nephrite is fault bounded by serpentinite of the Permian and older Shulaps Ultramafic Complex on the west and by slightly metamorphosed argillaceous sediments of the Mississippian to Jurassic Bridge River Complex on the east. The tabular shaped mass is 2.4 metres wide and trends northwest for 300 metres to where it is cut by a granitic intrusion. The deposit dips 75 degrees south. The east contact is bordered by a talc zone 0.3 metre wide. Cross fractures pervade the nephrite, trending 065 degrees and plunging 70 degrees southeast. The nephrite is described as good to fair quality, the quality being decreased by the presence of coarse tremolite patches, talc and opaque minerals.

The deposit was held and quarried by Oscar Messeser of B.C. Gem Supply Ltd. in the early 1970's. Birkenhead Jade produced 100 tonnes of nephrite in 1973.
