The Silver Hill occurrence is located on the west slope of Mount Rainey, 5 kilometres southeast of Stewart. Various showings were investigated in this area in the 1920s.

The occurrence consists of a number of quartz veins varying from a few centimetres to 6 metres in width hosted in granodiorite of the Eocene Hyder pluton (Coast Plutonic Complex) to the west and greenstone of the Lower Jurassic Unuk River Formation (Hazelton Group) to the east.

One vein occurs in a 0.3 metre wide shear zone, along its footwall, and is mineralized with magnetite, chalcopyrite and pyrite. The vein varies from 1.5 to 6 metres in width, strikes 130 degrees and dips 79 degrees southeast. A 0.3 metre chip sample across the shear assayed 3.1 grams per tonne gold, 103 grams per tonne silver and 0.5 per cent copper (Property File - McDougall, 1925).

A 0.15 to 0.20 metre wide quartz sulphide vein occurs to the north. It strikes 087 degrees for at least 30 metres and dips 85 degrees south. A 0.152 metre chip sample assayed 58.9 grams per tonne gold and 1080 grams per tonne silver (Property File - McDougall, 1925).

Various other quartz veins containing pyrite, sphalerite and galena assayed up to 14.60 grams per tonne gold and 240 grams per tonne silver (Minister of Mines Annual Report 1925, page 80).
