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 syn- formal structure. Locally the structures are complex resulting in dip reversals and repetition and omission of lithologies.

Sphalerite, pyrrhotite and minor galena occur in a north- east trending massive sulphide layer generally less than 1 metre thick. The layer is confined to a calcareous horizon consisting of calc-silicate gneiss and carbonates which is structurally underlain by well-layered hornblende gneiss and amphibolite and overlain by quartz-feldspar gneiss and pelitic schist.

The Main Boulder showing is probably a continuation of the same sulphide horizon that occurs in the New showing (082M 224), inferring the presence of a fault in the creek separating them. Structural complexities at the Main Boulder showing hinder trac- ing a small trenched outcrop of massive sulphides for more than a few metres.

A 0.6 metre chip sample assayed 23.45 per cent zinc, 4.88 per cent lead and 0.04 per cent copper (Fieldwork, 1979).
