The Hercules prospect is at approximately 2100 metres elevation on the south side of Ottawa Creek, which flows in a northeasterly direction into Lardeau Creek. The precise location is uncertain.

The property was owned by Mrs Jowett in the 1920s, at which time there were several open cuts and shallow shafts. It was held by Ainsworth Mines Limited in the 1930s. By 1934, there was a crosscut at 2100 metres elevation and "another portal up the hill to the east". The Hercules and adjacent Jewell [082KNW103] properties were explored by Loumic Resources Limited in 1989. At that time, the Hercules pits were found but not the adits.

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 (EMPE 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 Hercules claim is most likely underlain by green, gritty metasandstones and phyllites of the Broadview Formation. These rocks are folded and deformed and display the northwest strike and moderate to steep northeast dip that is found throughout much of the Lardeau Group on Silver Cup Ridge.

The Hercules veins are discordant. They strikes 040 and dip at 25 to 30 degrees to the southeast. They have been explored by means of open cuts and an adit, at 2103 metres elevation, driven as a crosscut that intercepts a vein 12.8 metres in. The upper vein is 0.08 to 0.15 metre wide on surface and highly oxidized. A sample of oxidized, mineralized gouge collected in 1934 assayed 10.28 grams per tonne gold, 281 grams per tonne silver, 7.2 per cent zinc and a trace of lead. There is a second, parallel vein exposed in the adit. It is composed of quartz and ankerite with pyrite and sphalerite, and small amounts of galena and chalcopyrite. On the west side of the adit, the vein is 0.48 metre wide and is particularly rich in sphalerite. On the east side, it has narrowed from 0.02 to 0.05 metre and contains more galena. The veins cut chloritic schist that has been variably altered and enriched in iron carbonate, quartz, sericite and "light green mica". The altered rock also contains disseminated pyrite and it is cut by stringers of quartz and calcite that contain minor sulphide. At another portal, uphill to the east, there is an outcrop of oxidized, brecciated, siliceous material that is associated with fractures that strike 130 degrees, parallel to the regional schistocity, and dip at a shallow angle to the southwest. There are also other workings. Loumic Resources assayed fourteen samples from the old dumps, workings and/or altered and mineralized zones; however only two gave anomalous values of silver and gold. Some samples contained anomalous values of arsenic. The company conducted a VLF EM survey and detected a number of graphitic schist horizons and pyritic fault zones.
