The Dominion target area consists of a main block of claims that straddles upper Sulphur creek. The target area is located approximately 35 kilometers southeast of Dawson City, and is accessible by government maintained resource roads.
The Dominion group of claims straddles a north-south trending thrust fault within the late Permian Klondike Schist. Chlorite rich schists and phyllites are dominant in the hanging wall of the thrust, and muscovite-rich quartzites with minor muscovite schist forms the footwall. Slivers of ultramafic rocks occur in the thrust fault planes, thought to be part of the late Paleozoic Slide Mountain terrane. Minor lenses of black graphitic schist are found within the Klondike Schist.
Work on the Dominion claims and area dates to 1896 with the start of placer mining and exploration along the Sulphur Creek and Dominion Creek drainages, which continue to present date. Prospecting in 1900 discovered gold bearing quartz veins. Several phases of exploration between 1900 and 1942 included numerous small exploration shafts and a 2600 foot long adit.
Exploration work resumed in 1980 through 2007 in the form of various short-lived soil sampling and trenching campaigns by successive exploration companies.
