The NCW occurrence is located a few kilometres east 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 (greenstone), metasediments and tectonically emplaced ultramafic rocks. The upper Mississippian to Permian Cache Creek Complex ultramafic rocks consist of peridotite, dunite and pyroxenite which are generally serpentinized.

The NCW nephrite jade showing occurs halfway between the ridge top and the valley floor, on a steep east-facing slope. The jade occurs at the margin of metamorphosed sedimentary rock and serpentinite. The lens trends 125 degrees and dips steeply southwest. Alteration at the contact is intense with much diopside present.

The jade outcrop is reported to cover a relatively large area on the slope. Quality of the material was reported to be difficult to discern due to partial oxidation of surface samples. The jade is reported to be hard and dense with an attractive bluish green colour.

In 1972, Frobex Ltd. mapped the property and Delphi Resources and Nephro-Jade Canada did the same in 1973.
