The JAMES LAKE showing is located 300 metres west of James Lake and approximately 18 kilometres northeast of Kelowna.

The showing consists of flat-lying, banded, calcium silicate skarn, which is overlain and underlain by gneissic rocks of the Upper Proterozoic Shuswap Metamorphic Complex. It is comprised of red, brown and green garnet, with local concentrations of fine-grained wollastonite and diopside. Pyrite and chalcopyrite are present in the skarn, and the enclosing gneiss is locally pyritic.

Skarn occurs for approximately 230 metres with about 100 metres of gneiss in between along a northwest trending roadcut (Personal Communication, Z.D. Hora, 1996). Also included in this occurrence is a smaller exposure of calcium silicate skarn, which outcrops for 20 metres along a roadcut, 680 metres southwest of the main exposure (Personal Communication, Z.D. Hora, 1996).

The property was examined for its precious and base metal potential by W.D. Yorke-Hardy, R.G. Irving and J.H. Wright in 1988-89. The results were discouraging and they concluded that the rock may be suitable for lapidary purposes. There are no records to suggest that the wollastonite potential has yet been evaluated.
