The Steadman showing is located on Williams Creek opposite Walkers Gulch, about 1.5 kilometres south of Barkerville.

The showing lies within the Barkerville Terrane of the Omineca Belt. The Barkerville Terrane is in thrust contact with Triassic Quesnel Terrane rocks to the west and Hadrynian to Lower Paleozoic Cariboo Terrane rocks to the east. The Barkerville Terrane in this region is underlain by the dominantly metasedimentary rocks of the Hadrynian to Lower Paleozoic Snowshoe Group. In this area the Snowshoe Group comprises limestone, phyllite and quartzite. These rocks have been regionally metamorphosed to greenschist facies.

The showing area is underlain by strata of both the Downey and Hardscrabble Mountain successions, Snowshoe Group. A near-vertical quartz vein up to two metres wide, bounded by clay gouge on both sides, crosscuts schist at about 120 degrees. Mineralization in the vein comprises pyrite, sphalerite, galena, chalcopyrite and arsenopyrite. In 1897, average assays of samples taken from the vein were about 34 grams per tonne gold (Minister of Mines Annual Report 1897, page 473).

In 1864, the Proserpine vein (093H 021) was found by Wilkinson and around the same time prospect shafts were sunk on several strike veins including the Proserpine and Steadman (Bulletin 38).
