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 20 to 30 centimetre thick sulphide layer is on strike with a similar layer at the Mist showing (082M 225), 1300 metres to the southwest. The layer which consists of disseminated sphalerite and minor galena and chalcopyrite is confined to a calcareous horizon which strikes 30 degrees and dips 40 degrees southeast. A 0.6 metre chip sample assayed 8.95 per cent zinc, 0.81 per cent lead and 0.05 per cent copper (Fieldwork 1979).
