The Shelley showing is 0.8 kilometre southwest of the confluence of Skwum and Lawless (Bear) creeks and 10 kilometres west-northwest of Tulameen. The St. Lawrence prospect (092HNE065) lies 550 metres to the west.

The showing is hosted in a sequence of Upper Triassic Nicola Group volcanics comprised of finely bedded, intermediate tuffs, felsic crystal tuffs and minor rhyolite, dipping shallow to moderately southwest. These rocks are locally altered and fractured, and have been metamorphosed up to greenschist facies.

Drilling over a north-south distance of 260 metres intersected narrow zones of alteration and shearing containing calcite, chlorite, quartz and minor epidote, accompanied by pyrite, minor arsenopyrite and chalcopyrite, and rare galena. Alteration and mineralization commonly occur along fractures, but are also developed along bedding planes. One shear zone with some fine-grained pyrite, arsenopyrite and galena analysed 0.053 per cent copper, 0.530 per cent lead, 0.420 per cent zinc, 61.1 grams per tonne silver and 0.370 gram per tonne gold over a core length of 0.91 metre (Assessment Report 17926, Appendix 4, hole 88-03, 26.2 to 27.1 metres). One alteration zone with large crystals of arsenopyrite, chalcopyrite and pyrite analysed 1.920 per cent copper, 0.002 per cent lead, 0.019 per cent zinc, 100.5 grams per tonne silver and 4.140 grams per tonne gold over a core length of 0.30 metre (Assessment Report 17926, Appendix 4, hole 88-01, 21.0 to 21.3 metres).

This showing was discovered by Bordeaux Resources Ltd. in 1988, while drilling coincident soil and geophysical anomalies. Goldwest Resources Ltd., Serem Ltd. and Bordeaux Resources completed geological, geophysical and geochemical surveys over the area between 1982 and 1987 while searching for stratabound massive sulphide mineralization, which outcrops in three occurrences to the west (St. George, 092HNE064; St. Lawrence, 092HNE065; Liverpool, 092HNE066).
