The Quartz-Hanna showing is located about 3.0 kilometres west of Hastings Arm of Observatory Inlet, between Carney and Upper Dam lakes. The showing is located about 580 metres east of the Deadwood occurrence (103P 243).

The region is underlain by a roof pendant, consisting of volcanic and sedimentary rocks, within the Eocene Coast Plutonic Complex. These pendant rocks have been correlated with Middle-Upper Jurassic Hazelton Group rocks and overlying upper Middle to Upper Jurassic Bowser Lake Group sedimentary rocks (Geological Survey of Canada Open File 3453). The Hazelton rocks consist of variably chloritized pillow and massive basalt with minor mafic tuffs. The overlying Bowser Lake sediments consist of siltstone and sandstone with minor chert and limestone. These rocks are deformed by two phases of folding which trend northeast.

The showing consists of a well defined quartz vein in argillite, about 90 to 120 metres east of the greenstone/argillite contact. The vein, 1.8 to 5.5 metres wide, parallels bedding with a strike of 170 degrees, dipping 55 to 70 degrees east. The vein has been exposed for 600 metres along strike by stripping and trenching.

The vein consists of barren to sparsely mineralized milky white quartz, with traces of disseminated pyrite, pyrrhotite, chalcopyrite, galena and sphalerite. A well mineralized sample from the vein assayed 0.10 per cent copper, 61.7 grams per tonne silver and 0.34 gram per tonne gold (Property File - Bancroft, J.A., 1918, Report, page 57).
