The CK area is underlain by metasedimentary rocks of the Precambrian-Paleozoic(?) Shuswap Metamorphic Complex consisting of quartz-feldspar-hornblende gneiss, amphibolite, calc-silicate gneiss and minor quartzite and marble. 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 synform. Locally the structures are complex resulting in dip reversals and repetition and omission of lithologies.
A sulphide layer, up to 2.1 kilometres long and 7.8 metres wide, is confined to a calcareous horizon that trends southeast on the southern limb of the synform. The calcareous horizon consists of calc-silicate gneiss and carbonates which is structurally underlain by hornblende gneiss and amphibolite and overlain by quartz-feldspar gneiss and pelitic schist.
The sulphide layer consists of massive sphalerite and pyrrhotite, minor galena and trace chalcopyrite. Gangue quartz, diopside, calcite, amphibole and plagioclase are common and fluorite and vesuvianite occur locally. A 0.6 metre chip sample assayed 21.85 per cent zinc, 4.41 per cent lead and 0.057 per cent copper (Fieldwork 1979). Drilling results gave an average grade of 11.2 per cent zinc and 1.6 per cent lead over 2.5 metres along a 600 metre strike length (Assessment Report 7213).
The CK property overlies 12 mineralized lead-zinc occurrences where indicated reserves are 1,490,365 tonnes grading 8.6 per cent zinc, 1.4 per cent lead and 8.5 grams per tonne silver (George Cross News Letter November 26, 1986). See 082M 137, 225-228, 245-251.
In 1998, V.G. Wiens prospected the claims. BWI Resources Ltd. purchased the CK claims in 1999.
