The Gold Star claims are located on Kitselas Mountain, three kilometres southwest of Usk. The claims were originally staked and developed by New Gold Star Mines Limited in the late 1960s.
Andesite and basalt of the probable Jurassic age Hazelton Group, are intruded by a porphyritic gabbro sill of the Cretaceous to Tertiary Coast Plutonic Complex. The sill strikes 070 degrees for about 50 metres, dips 30 degrees northwest and is about 17 metres wide. All rocks are cut by northeast trending faults.
Chalcopyrite, pyrrhotite, and pyrite occur as disseminations and blebs within the intrusive. A 6.9 metre channel sample assayed 0.28 per cent copper, 13.7 grams per tonne silver and trace nickel (Assessment Report 2365).
On #4 Creek, 400 metres northwest of the above 4A Creek zone, bornite and chalcopyrite occur as disseminations, associated with mafic minerals in a porphyritic gabbro. A 4.6 metre chip sample assayed 0.33 per cent copper and 1.7 grams per tonne silver (Assessment Report 2365).
