The Dome occurrence is located in the head waters of Adit Creek, a tributary of the Kennedy River.

Upper Triassic andesites and andesitic breccia and tuffs of the Karmutsen Formation, Vancouver Group are intruded by granodiorite of the Early to Middle Jurassic Island Intrusions and Tertiary dacitic dikes. The rocks are cut by northwest trending faults which typically show intense shearing and local sericitization, silicification and pyritization over widths of 0.5 to 2 metres.

The Dome vein is hosted in well brecciated andesitic volcanics, within a wide shear zone which appears to be a splay off the Canoe Creek fault. The vein strike is approximately 095 degrees. The ore mineralogy is not reported.

One sample taken across 46 centimetres assayed 11.66 grams per tonne gold, 41.14 grams per tonne silver and a trace of copper. Another sample contained 44.57 grams per tonne gold, 24.00 grams per tonne silver and 1.6 per cent copper (Minister of Mines Annual Report 1923). See also the Tommy K (092F 033) for further information.

In 1981, W. Ejtel completed a program of prospecting and sampling surface exposures of the area. In 1984 and 1985, Int. Phoenix Energy completed programs of geochemical sampling, geological mapping, trenching and ground magnetic and electromagnetic surveys. In 2009 and 2010, G4G Resources Limited completed a program of prospecting and remote sensing, consisting of spectral analysis and synthetic aperture radar analyses, on the area as the G4G property.
