The area is underlain by metasedimentary rocks of the Shuswap Metamorphic Complex consisting of quartz-feldspar- hornblende gneiss, amphibolite, calc-silicate gneiss and minor quartzite and marble of unknown but probable Paleozoic age. The metasediments are cut by pegmatites and granitic intrusives.
The general structure of the area is composed of an east- facing succession folded into a broad open, east-plunging synformal structure. Locally the structures are complex resulting in dip reversals and repetition and omission of lithologies.
A sulphide layer, less than one metre wide and up to 30 metres long is confined to a calcareous horizon which trends northerly and dips 40 degrees east.
The sulphide layer consists of massive and disseminated sphalerite and pyrrhotite and minor galena and chalcopyrite. A 0.6 metre chip sample assayed 20.70 per cent zinc, 2.66 per cent lead and 0.05 per cent copper. A drill hole intersection returned 3.98 per cent zinc, 0.71 per cent lead, 0.01 per cent copper, 6.2 grams per tonne silver and 0.24 grams per tonne gold across 1.1 metres (Fieldwork 1979).
