The Dominion showing is located 7.5 kilometres southeast of Stewart, above the Kate Ryan Glacier. An adit, driven between 1927 and 1929, attempted to intersect veins that outcrop in the cliffs above it.
The showing consists of a few lenticular quartz veinlets containing pyrite, chalcopyrite, sphalerite and galena. These are hosted in north west striking, moderately northeast dipping, schistose tuffs and flows of the Lower Jurassic Unuk River Formation (Hazelton Group).
