The Alpine prospect is at 2150 metres elevation on the west side of Silver Cup Ridge. The Alpine (L.6468) tenure is at the north end of a small pothole lake near the head of Laughton Creek, which flows to the southwest into Trout Lake. There is a shaft, 12.2 metres deep. The tenure was owned by Mrs. Jowett in the 1920s and was covered by the Bug claims, owned by Golden Rule Resources Limited, in 1981.

The Trout Lake area is underlain by a thick succession of sedimentary and volcanic rocks of the Badshot Formation and Lardeau Group near the northern end of the Kootenay arc, an arcuate, north to northwest trending belt of Paleozoic and Mesozoic strata that is now classified as a distinct, pericratonic, terrane. The arc rocks are bordered by Precambrian quartzite in the east and they young to the west, where they are bounded by Jurassic-age intrusive complexes. They were deformed during the Antler orogeny in Devonian-Mississippian time and were refolded and faulted during the Columbian orogeny, in the Middle Jurassic. A large panel, the "Selkirk allochthon", was later offset to the northeast by dip-slip motion along the Columbia River Fault.

The Badshot Formation is composed of a thick Cambrian limestone that is a distinctive marker horizon in the Trout Lake area. It is underlain by Hamill Group quartzite and it is overlain by a younger assemblage of limestone, calcareous, graphitic and siliceous argillite and siltstone, sandstone, quartzite and conglomerate, and also mafic volcanic flows, tuffs and breccias, all of which belong to the Lardeau Group. The rocks are isoclinally folded and intensely deformed, but only weakly metamorphosed. They occur as intercalated beds of marble, quartzite and grey, green and black phyllite and schist. Fyles and Eastwood (EMPR BULL 45) subdivided the group into six formations (Index, Triune, Ajax, Sharon Creek, Jowett and Broadview) of which the lowermost (Index) and uppermost (Broadview) are the most widespread. The Triune (siliceous argillite), Ajax (quartzite) and Sharon Creek (siliceous argillite) are restricted to the Trout Lake area. The Jowett is a mafic volcanic unit.

The Alpine claim covers a short section through the Broadview Formation. The rocks are isoclinally folded, highly deformed and locally schistose. They display the regional northwest-trending strike and moderate to steep northeast dip found throughout the Silver Cup Ridge area. On the Alpine claim, there is a 0.91 metre wide vuggy quartz vein exposed in open cuts over level ground for a distance of approximately 60 metres. The vein strikes north and dips at 84 degrees to the east. It contains pyrite, galena and sphalerite and an average sample collected in 1914 assayed 3.43 grams per tonne gold, 113.1 grams per tonne silver and 4.6 per cent lead. At that time, it was deemed to be relatively low grade and a relatively unattractive target as it would have to be worked by shafts.
