The Chris prospect is located at the head of Pipestem Inlet, approximately 750 metres south west of Skull Lake.

The area is underlain by volcanic rocks of the Upper Triassic Vancouver Group, Karmutsen Formation, consisting mainly of basaltic pillow lavas, pillow-breccia and massive basaltic flows. These are overlain by massive beds of limestone of the Quatsino Formation, also of the Vancouver Group. These are in turn overlain by Lower Jurassic Bonanza Group volcanics composed of tuff and/or felsic flows. The strata are in contact to the south with dioritic rock of the pre-Jurassic Westcoast Complex.

A major east trending fault, cutting the stratigraphy along and extending east from the head of Pipestem Inlet, serves as a conduit for various intrusives. A quartz feldspar porphyry intrudes the layered rocks at the inlet's head, in the form of small plugs and related dikes. Near the Quatsino-Karmutsen contact there is a small exposure of diorite. Scattered exposures of basalt dikes intrude the limestone parallel to the fault.

Locally, several zones of skarn mineralization were reported to occur in the rocks at the head of Pipestem Inlet. These showings are from 0.5 to 10 metres in width. Several showings consisting of disseminations, pods and streaks of different combinations of pyrite, chalcopyrite, galena and sphalerite occur in skarn altered limestone and at one location within epidotized and silicified volcanics. Elsewhere a narrow showing of galena and sphalerite occurs in siliceous fine- grained quartz feldspar porphyry near its contact with limestone.

In 1970, Pacific Petroleums Ltd. completed a program of geological mapping, a geochemical survey and grab sampling on the area as the Chris claim. This work identified a copper anomaly over an area of 300 by 150 metres and two grab samples of mineralized tuff and tremolite rock assayed 0.21 and 1.88 per cent copper, respectively (Assessment Report 03062).

In 1980 and 1984, Landmark Resources Ltd. completed programs of soil geochemical sampling and geological mapping on the area as the Island and Pipe claims. A rock sample (2652) yielded 0.78 per cent copper, 0.34 per cent zinc and 38.0 grams per tonne silver, other samples yielded up to 2.7 per cent zinc and 112.0 grams per tonne silver (Assessment Report 13308).
