The Giant (Midget) showing is exposed immediately north of Nun Creek and at the west edge of the Priest River canyon, at an elevation of 1220 metres. The vein strikes northerly and dips very steeply to the west. The vein is composed chiefly of white quartz and is about 3 metres thick where exposed. Scattered grains and masses of sulphides, including pyrite, tetrahedrite and galena are present in the vein.
The wallrocks are described as schists conformable in attitude to the vein; recent mapping shows that they belong to the Mount Nelson Formation, part of the Middle Proterozoic Purcell Supergroup (see Brown et al., Fieldwork 1994). They are regionally metamorphosed to greenschist grade, near the boundary between chlorite and biotite-almandine facies (Geological Survey of Canada Map 1714A).
A small (50 tonne-per-day) mill was set up on the property in 1968, but production was limited to trial runs, and no results are available except that "the vein appeared to contain about 1 per cent each of copper and lead where mining was done" (Minister of Mines Annual Report 1968).
