The Dome occurrence is located on a small knoll west of Eldorado Creek, approximately 1 kilometre north-northwest of its junction with Gun Creek.

The area is underlain by coarse clastic sedimentary rocks of the Upper Triassic Hurley Formation (Cadwallader Group) and serpentinite ultramafic rocks of the Permian Bralorne-East Eliza Complex.

Locally, rusty shears in a greenstone host two narrow quartz-ankerite-calcite veinlets with minor disseminated pyrite and arsenopyrite mineralization. In 1986, a sample assayed 2.0 grams per tonne gold over 0.1 metre (Assessment Report 15399).

In 1983, X-Cal Resources prospected and sampled the area as the Dome property. In 1984 and 1985, Pirates Gold completed programs of rock, silt and soil sampling and a ground electromagnetic survey on the area as the Eldorado 1-3 claims. During 1986 through 1990, Berkley Resources completed programs of geochemical sampling, prospecting and a 45.2 line-kilometre airborne geophysical survey on the area.
