The Bowron River showing is located approximately 58 kilometres east-southeast of the town of Prince George, south of Highway 16 along the Bowron River. The showing is in the Cariboo Mining Division.

The area is underlain by the Mississippian to Permian Antler Formation (Slide Mountain Group), which consists of fault-bounded, mainly basaltic volcanic rocks juxtaposed within a wide variety of Paleozoic to Mesozoic sedimentary and metasedimentary rocks. Within the Antler Formation, in fault contact and likely also unconformable contact, is a horizon of upper Eocene undivided sedimentary rocks that host the Bowron River coal beds. This horizon is a 600-metre thick sequence of conglomerate, sandstone and shale that trend northwest for approximately 24 kilometres along the Bowron River valley. Bedding strikes 140 degrees and dips 20 to 60 degrees northeast. The basin is bordered by tuffs, breccia, greenstone, and minor chert and limestone of the Mississippian Slide Mountain Group.

Radioactive conglomerate and greenstone were intersected over 50 metres in drillholes. The radioactivity occurs beneath the main coal seams, in the basal rock in contact with the Slide Mountain rocks. Thucolite, which is a hydrocarbon with uranium, and germanium were also identified in shale and coal. A seam sample from a section along the river near the old mine site to the north assayed 0.008 per cent uranium. The ash from the sample assayed 0.058 per cent molybdenum and 0.108 per cent vanadium (GSC Paper 70-52). A sample assayed 186 grams per tonne germanium (Assessment Report 4438).

Please refer to the Bowron River (MINFILE 093H 005) and the Bear River (MINFILE 093H 130) coal occurrences for descriptions on the coal measures.
