The John occurrence is located on the east side of Perry Creek, approximately 650 metres northeast of its junction with Wuhun Creek.
The Perry Creek area is underlain by sedimentary rocks of the mid-Proterozoic Creston Formation (Purcell Supergroup). The middle Creston Formation consists of a sequence of medium-bedded, grey to maroon, fine-grained quartzite with intercalated thin beds of grey phyllite. A stockwork of quartz veinlets, up to 7 centimetres thick, is found within the quartzite. A few of these quartz stringers carry up to 2 per cent hematite and minor chalcopyrite. To the west, this sequence is overlain by the upper Creston succession of thinly interbedded, light and dark-green argillites and green siltstone, which are locally phyllitic. To the northwest, the sequence is overlain by the Kitchener Formation.
Locally, as exposed by trenching, a strongly folded quartz phyllite hosts segregated quartz stringers with gold values. The quartz stringers strike north 30 degrees east and dip 80 degrees to the south east.
In 1980, two chip samples (4049 and 4050) yielded 0.45 and 0.41 gram per tonne gold over 4.5 and 12 metres, respectively (Assessment Report 8598).
In 1978, Meridian Resources completed a program of geochemical sampling and geological mapping on the area as the John group. During 1979 through 1985, Gallant Gold Mines completed programs of rock, soil and silt sampling, trenching, geological mapping and ground electromagnetic and magnetic surveying on the area as the Perry Creek property. In 1987 and 1988, Chapleau Resources completed programs of soil, silt and rock sampling, trenching and geological mapping on the area as the Racki claims, Morgan property. In 1988 and 1989, the area immediately west was prospected as the Beaver claims. In 1990, Swift Minerals completed a 77.0 line-kilometre airborne geophysical survey on the area. Also, at this time Chapleau Resources completed a 14.8 line-kilometre combined ground electromagnetic and magnetic survey on the area as the Racki claims. In 1991, Dragoon Resources collected rock samples in the area.
