The Jade 1 occurrence is located within a few hundred metres east of the north end of Provencher Lake, about 90 kilometres east-southeast of the community of Dease Lake.

The area is underlain by Mississippian to Triassic Cache Creek Complex rocks including metavolcanics (including greenstone), metasediments and tectonically emplaced ultramafic rocks. The upper Mississippian to Permian ultramafic rocks consist of peridotite, dunite and pyroxenite which are generally serpentinized.

A talcy jade band occurs between serpentinite and sheared metamorphic rock. In 1975, one of two short drillholes put down by Nephro-Jade Canada intersected 30 centimetres of poor quality jade. This showing was first noted by the above company in 1973.
