The KW occurrence is located along a road cut near the lower end of Blowdown Creek.

The region is underlain by pelitic sediments and schists of the Mississippian to Jurassic Bridge River Complex, intruded by dominantly granodioritic stocks of the Jurassic to Tertiary Coast Plutonic Complex.

Locally, a shear zone, striking at 230 degrees and dipping 80 degrees east, hosts quartz veins with molybdenite mineralization.

In 1979, a 1.75-metre sample assayed 0.037 per cent molybdenite, while a 50-metre random chip sample yielded 0.012 per cent molybdenite (Assessment Report 79005). Float or rock chip samples of a pelitic schist with quartz veining, taken the same year, assayed up to 1.0 gram per tonne gold (Assessment Report 79005).

In 1979, Kennedy Resources completed a program of prospecting, geochemical sampling and a 10.5 line-kilometre ground VLF-EM survey on the area as the KW claims. In 1980, Denison Mines completed a program of geochemical sampling and geological mapping on the area as the Snow claims. The following year, Kennedy Resources completed a ground induced polarization survey on the area. In 2008, Pacific Cascade Minerals completed a 343.0 line-kilometre airborne magnetic survey on the area.
