The Quebec showings are on Frenchman Creek, 10 kilometres southwest of Field, in Yoho National Park. The occurrence is underlain by red weathering, highly cleaved calcareous slates and slates with thin limestone interbeds, of the Middle Cambrian Chancellor Group.

Quartz-calcite veinlets cut the slates and are mineralized with galena, tetrahedrite, azurite, malachite, pyrite and arsenopyrite.

The showings were staked as the Quebec claim (Lot 511) which was Crown-granted in 1902. The Pioneer Mining Company held the property in 1885, installed a 10-stamp mill and a tramway about 3.2 kilometres long with wooden rails. Approximately 18 tonnes of ore had been transported before a forest fire destroyed the tramway in June 1887. The workings included a lower adit about 61 metres long with an 18-metre shaft at the end, and an upper adit 53 metres long.
