Capsule Geology

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.

Thin bands and disseminated sphalerite and minor galena occur in silicified calc-silicate gneiss near the closing of the Raft synform. A drill hole (DDH 80-12) intersected 2 per cent combined zinc and lead over 0.45 metres (Assessment Report 8317).
