The Badshot occurrence is on Badshot Mountain, on the divide between Perry Lode Creek (a tributary of Gainer Creek which drains to the southwest into Lardeau Creek) and Badshot Creek (a tributary of Marsh Adams Creek that flows to the northeast into the Westfall River). The Badshot (L.1105) and Perry Lode (L.4568) tenures straddle the ridge crest at 2150 metres elevation. Other tenures in the group include the Blizzard (L.7256), No.25 (L.1106), Butte (L.4569), Lone Pine (L.4570) and Lime Mountain.

The Badshot area was first explored in the early 1890s when lenses of high-grade lead-silver mineralization were located in a quartz vein in the limestone. By 1896, an inclined shaft had been sunk 30 metres, a tunnel had been developed to tap the vein and 54.4 tonnes of hand cobbed ore (averaging 7714 grams per tonne silver, 75 per cent lead and a small amount of bismuth) had been prepared for shipment. Over the succeeding years, the shaft was deepened and the vein was traced to depth, where it narrowed but continued to contain ore-shoots. In 1904, Alex McLean & Associates leased the mine, operated it for about two months and produced 25 tonnes averaging 6068 grams per tonne silver and 56 per cent lead. Two further shipments were reported in 1914. One was for 20 tonnes and assayed 5383 grams per tonne silver, 56 per cent lead and 4.6 per cent zinc. The other was for 29 tonnes grading 6069 grams per tonne silver and 56 per cent lead. By 1929, the workings were in bad condition and had been deserted for many years. At that time, they were described as being a crosscut 20 metres long, from the end of which were drifts along the vein. The southeast drift was linked by an inclined shaft to surface and had an internal shaft developed at its end.

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 Badshot area is in a similar stratigraphic and structural setting to the neighbouring Black Prince [082KNW034]. It straddles Badshot Formation strata and the basal part of the overlying Index Formation. The Badshot limestone is a thick, massive, grey marble unit that is a an important stratigraphic and topographic marker throughout the Trout Lake area. In the early 1900s it was known as the "lime dyke". The limestone is overlain by a thick succession of black and grey phyllite that contains local, intercalated beds of calcareous phyllite, limestone and quartzite. The rocks are tightly isoclinally folded and highly deformed. They have an axial plane schistocity that displays the regional northwest trend and steep, southwest dip found throughout the eastern part of the Trout Lake area. There is a considerable amount of fold repetition to the stratigraphy.

The Badshot quartz vein lies at the foot of a bluff along the northwest trending contact between a limestone band and phyllite. It dips at 30 degrees to the northeast. The vein, is approximately 0.91 metre wide and contains a 0.2 metre wide high-grade pay streak. The vein has been traced to depth, where it narrows but continues to contain high-grade shoots. The veins consist of white, sugary quartz and calcite with galena, which contains grey copper (tetrahedrite), pyrite and sphalerite. In 1914, selected coarse-grained galena samples were individually assayed and found to contain 4800 to 4944 grams per tonne silver and 80 per cent lead. Fine-grained galena from the same location contained 11833 grams per tonne silver and 69 per cent lead. The latter probably contained some tetrahedrite.
