The Silverslope Creek occurrence is situated at the headwaters of the southeast branch of Silverslope Creek in Yoho National Park, about 30 kilometres east of Golden.

Reddish weathering slates of the Middle Cambrian Chancellor Group strike 125 degrees and dip 40 to 45 degrees south. Galena, sphalerite and pyrite with minor chalcopyrite and possibly argentite, occur as irregular lenses and in calcite stringers in a bed of partly recrystallized limestone 1.8 metres thick, that is interbedded in the slates. An average sample assayed 15.33 per cent lead, 6.87 per cent zinc, 0.35 per cent copper and 154.2 grams per tonne silver (Geological Survey of Canada Memoir 55, page 223).

A tunnel, above tree line, is about 61 metres long and was started 22 metres downslope of the mineralization in order to intersect it at greater depth, but was still a few metres from where the ore would be reached (Geological Survey of Canada Memoir 55, page 223).
