The exact location of the Docia showing is not known and was reported to lie east of, and adjoining, the Red Top property (104A 021) approximately 27 kilometres northeast of Stewart (Minister of Mines Annual Report 1929).

The area is underlain by east striking, north dipping andesitic volcanics of the Lower Jurassic Unuk River Formation (Hazelton Group). A vein of nearly solid galena, 30 to 36 centimetres wide, trends east and dips south. The vein contains minor chalcopyrite and pyrite (Minister of Mines Annual Report 1929).

In 1929, the Docia property was reported to be owned by the McNeil brothers. Two small opencuts, about 15 vertical metres apart, were reported that year. The subsequent history of the showing is unknown. In 1994, a helicopter-supported program on the Golden Crown property by Canstar Ventures Corporation consisted of collecting 450 samples including 369 rock composite and chip, 2 soil, 58 stream sediment and 21 checks in ten target areas.
