The Kam 1 occurrence is located near the Duffey Lake road, west of Blowdown Creek.

The region is underlain by metasedimentary rocks of the Mississippian to Jurassic Bridge River Complex, intruded by dominantly granodioritic stocks of the Jurassic to Tertiary Coast Plutonic Complex.

Locally, biotite schists in association with fine-grained felsic (aplite) dikes host sulphide-bearing quartz veins and stockworks. The veins vary from 5 to 25 centimetres wide in swarms over 2 to 5 metres in width and contain primarily quartz with minor feldspar and trace muscovite. Sulphide mineralization consists of pyrite, pyrrhotite, chalcopyrite, galena and molybdenite.

In 1992, a grab sample (MGS-92-107) from a road cut is reported to have assayed 45.6 grams per tonne gold, 108.8 grams per tonne silver and 0.045 per cent molybdenum, while the following year samples yielded values up to 0.42 gram per tonne gold, 5.0 grams per tonne silver and 0.077 per cent molybdenum (Assessment Report 23039).

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 1992 and 1993, the area was prospected as the Kam 1 claim.
