The St. George prospect is 1.2 kilometres west-southwest of the confluence of Skwum and Lawless (Bear) creeks and 11 kilometres west-northwest of Tulameen. The St. Lawrence prospect (092HNE065) lies approximately 400 metres to the southeast.
The area southwest of Lawless Creek is underlain by a sequence of dark grey to black pelitic schist, limestone (marble) and chlorite schist (greenstone) of the Upper Triassic Nicola Group. These rocks strike northwest and dip 30 to 70 degrees southwest towards the contact with nearby granodiorite of the Late Jurassic to Early Cretaceous Eagle Plutonic Complex. The upper part of this sequence is intruded by feldspar porphyritic dikes and sills, likely originating from the complex. Stratabound massive sulphides are developed in this area, where noncalcareous pelitic schists grade into overlying calcareous schists and marbles.
This deposit consists of a lens of disseminated to massive sulphides dipping 60 degrees west. The lens has been traced along strike for 27 metres and downdip for 55 metres in two shafts. The sulphides occur in limestone over widths of up to 4.3 metres, and are better developed in the hangingwall of the bed. The wallrocks are comprised of quartz-chlorite-biotite schist. The deposit lies 100 metres east of a feldspar porphyritic dike and several hundred metres east of the Eagle Plutonic Complex.
Mineralization consists of pyrite and pyrrhotite, with lesser chalcopyrite, and minor sphalerite and galena, in a gangue of calcite and minor quartz. A grab sample of pyrite and pyrrhotite in limestone from the dump of the western shaft analysed 1.177 per cent copper, 0.011 per cent lead, 0.312 per cent zinc, 400.6 grams per tonne silver and 15.2 grams per tonne gold (Assessment Report 15419, Appendix 3, sample RAM 3R).
The St. George prospect was explored by two shafts, with several drifts and crosscuts, by C.F. Law and the Similkameen Mining and Smelting Company between 1903 and 1913. A total of 27 tonnes were mined by C.F Law in 1916 grading 34 grams per tonne gold, 533 grams per tonne silver and 0.394 per cent copper (Minister of Mines Annual Report 1960, page 51). Cominco Ltd. drilled around the sulphide lens in 1960, to determine its lateral extent. The prospect was more recently sampled and mapped by Goldwest Resources Ltd., Serem Ltd. and Bordeaux Resources Ltd. between 1980 and 1986.
