The Bower Creek occurrence is located on Bower Creek, 13 or 16.25 kilometres above its mouth about 53 kilometres northeast of Thutade approximately 194 kilometres north-northwest of the community of Germansen Landing.

Regionally, the Bower Creek showing is hosted within a regional, northwest striking fault-bound sequence of Cambrian to Ordovician rocks. These rocks have been divided into a lower sequence, the Lower Cambrian Atan Group, and an upper sequence, the Cambrian to Ordovician Kechika Group. The Atan Group, in the Toodoggone map area, is composed of three units. From oldest to youngest these are: quartzite with minor pebble conglomerate; impure quartzite, shale, local sandstone, conglomerate; and limestone, siltstone and dolomite. The Kechika Group, of which rocks of the Bower Creek showing belong, is composed of phyllitic limestone, calcareous shale, limestone and phyllite.

The Bower Creek showing comprises quartz veins with pyrite and chalcopyrite, galena, sphalerite, tetrahedrite and some cobalt nickel arsenides.

In 1927, the discovery of the veins was made by E. Brunlund while prospecting for the Consolidated Mining and Smelting Company. The property and surrounding area was prospected from 1927 to 1930. The work done on the veins indicated that they were much narrower than initially indicated on surface. Mineralization of sufficient grade and magnitude to suggest a commercial operation was not discovered (Energy, Mines and Resources Canada Mineral Policy Corporation Files - Cominco Limited Annual Report 1929).
