The Ket 20 occurrence is located at 1204 metres elevation, 6.5 kilometres southwest of Bridesville, British Columbia. The property has been owned by Crownex Resources (Canada) Ltd. since 1991. No previous work is known.
The showing is underlain by a sequence of metasediments and metavolcanics of the Permian to Carboniferous Anarchist Group. Greenstone, quartzite, greywacke, limestone and locally paragneiss comprise the Anarchist Group. These have been intruded by granodiorite, quartz diorite, granite, quartz monzonite, monzonite and syenite of the Middle Jurassic Nelson intrusions.
Lithologies encountered at the Ket 20 occurrence include greenstone, quartzite, minor marble and serpentinized peridotite. Skarn has been developed locally along the northeast side of the serpentinite. Talc alteration is closely associated with the serpentinite. Biotite hornblende granodiorite occurs immediately to the northeast.
Mineralization found at the Ket 20 showing consists of stringers and pods of anhedral magnetite hosted in the serpentinite. A nickel (fuchsite) or chromium (mariposite) mica has also possibly been identified. Minor pyrite also occurs.
Significant nickel and chromium values were obtained from rock geochemical samples of serpentinite. Sample 90-CM-317R yielded 0.14 per cent nickel and 0.12 per cent chromium. Samples 90-CM-341R analysed 0.10 per cent chromium and 0.12 per cent nickel (Assessment Report 21001). Similarly, 90-CM-342R analysed 0.14 per cent chromium and 0.17 per cent nickel (Assessment Report 21001). Two other samples, 90-CM-527R and 90-CM-528R, yielded equally anomalous chromium and nickel.
