The K.C.M. occurrence is located on a north-south trending ridge, approximately 400 metres west of Punch Bowl Lake and 40 kilometres southwest of Princeton.

The area is underlain by Lower-Middle Jurassic Dewdney Creek Formation (Ladner Group) sediments comprised mainly of interbedded sandstone, siltstone, argillite and conglomerate. The bedding generally trends north to northwest with variable dips.

Intruding the sedimentary rocks are dikes, sills and small plugs of diorite. The age of these intrusions ranges between Early Cretaceous to late Tertiary. The diorite is generally fine grained with abundant hornblende, feldspar and minor quartz. Locally, the diorite contains xenoliths or breccia fragments of a slightly more mafic igneous rock. Northwest-trending faults occur adjacent to the diorite intrusions and strong quartz sulphide is associated with the fault contacts.

Locally, quartz-pyrite-galena mineralization occurs in a vein within a northwest- trending fault zone at the diorite/sandstone contact. The vein has been exposed by trenching for approximately 25 metres and is reported to have an average width of 30 centimetres. The vein pinches to less than 1 centimetre to the south in a clay altered shear zone and swells to 60 centimetres wide to the north but is void of sulphides. Disseminated pyrite and arsenopyrite also occurs here.

In 1987, a 0.4 metre chip sample across the vein assayed 0.19 gram per tonne gold, greater than 100 grams per tonne silver, 0.17 per cent lead, 0.06 per cent zinc, 0.012 per cent copper and 0.57 per cent arsenic (Assessment Report 16279).

In 1988, rock chip samples from the trenches yielded from 0.080 to 0.285 gram per tonne gold (Assessment Report 17824).

In 1991, a sample analysed 0.624 gram per tonne gold, 0.406 gram per tonne silver, 0.044 per cent copper, 0.097 per cent lead, 0.36 per cent zinc and 0.013 per cent arsenic (Geological Fieldwork 1991, page 61, sample RS90C-10E).

A second area of mineralization, located 80 metres to the northwest along the projected trend of the main vein, consists of quartz-calcite veins and siliceous zones near diorite dikes. Scarce sulphide mineralization occurs along an east-west trending fault zone, which contains abundant orange-brown quartz-carbonate breccia in widths up to 2 metres. A sample taken from the east end of the fault, in 1987, assayed 0.06 gram per tonne gold (Assessment Report 16279).

The area was originally prospected in the 1930’s and 1940’s and some placer gold was noted in Punch Bowl Creek. During 1984 through 1987, Kam Creek Mines completed programs of prospecting, rock and soil sampling and geological mapping on the area as the Punch Bowl and K.C.M. claims. In 1988, Locke Rich Minerals completed a program of rock and soil sampling, geological mapping and minor trenching on the area.
