The Spokane occurrence is located west of Jim Kelly Creek, approximately 6 kilometres northwest of its junction with the Similkameen River.
The area is underlain by sediments of the Lower to Upper Cretaceous Pasayten Group, which are composed of altered, fractured and fissured sandstone, conglomerate and pelite. These are intruded by foliated diorite of the late Jurassic to early Cretaceous Eagle Plutonic Complex. To the north of the showing, the upper Oligocene-lower Miocene Coquihalla Formation, composed of basalt, rhyolite, tuff and agglomerate, caps Coquihalla Mountain.
Locally, two open-cuts expose an east-trending fracture zone in schistose host rock. The fracture is infilled by irregular quartz veinlets carrying pyrite over a width of approximately 0.9 metre. Later reports, in 1937, describe a 12.5 to 65-centimetre wide quartz vein, exposed by a 6-metre open-cut and a short adit, hosting pyrite, minor chalcopyrite and trace galena in a sheared greenstone. The vein strikes north 80 degrees west and dips 60 degrees north.
In 1913, a sample across 0.9 metre assayed 4.11 grams per tonne gold (Minister of Mines Annual Report 1913, page 233).
In 1937, a sample across 66 centimetres yielded 10.9 grams per tonne gold and 68.4 grams per tonne silver (Minister of Mines Annual Report 1937, page D22).
In 1988, a sample (TP-88-024) of quartz vein exposed by former trenches assayed 27.0 grams per tonne silver and 4.70 grams per tonne gold, while other samples (TP-88-013) yielded up to 0.321 per cent copper, 50.0 grams per tonne silver, 0.05 gram per tonne gold and greater than 1.0 per cent strontium (Property File - T. M. Parsons [1989-01-01]: Property Submission On Jim Kelly Creek, Wolfe Creek And Lone Pine Creek Mineral Claims).
The area has been explored since the late 1890’s. In 1909, copper-gold ore was reportedly removed by James Kelly but the exact location of this is unknown. In 1914, the John Bull, Spokane, Vancouver, Marsellaise, Superior and Gold Mountain groups were explored. In 1926, exploration was done on the Silver Bell and Belmont claims, thought to be the same vein as previously worked by James Kelly. In 1937, the Evening Star group was worked by W.B. Marks.
In 1965 and 1966, Bethex Explorations completed 32 trenches, totalling 5400 metres, and five diamond drill holes, totalling 850 metres, on an area of possible porphyry copper mineralization located approximately 600 metres to the south west on the P.R. and David claims. The following year, Atlas Explorations prospected and sampled the area. During 1982 through 1985, Minequest Exploration completed programs of prospecting and soil sampling the area as the Aura claims. In 1989, T.M. Parsons prospected and sampled the area as the Fortune and Great Scott claims.
