The Dog Creek occurrence is located approximately 1 kilometre from the mouth of Dog Creek, south of the west end of Germansen Lake. The location is centred on a mineralized quartz vein and includes a hand-trenched gossan zone found approximately 400 metres to the south, on the east bank of the creek.

Regionally, this occurrence lies within the Middle Triassic to Lower Jurassic Takla Group, a volcanic and sedimentary assemblage. To the east, across the Manson fault zone, Upper Paleozoic oceanic rocks of the Nina Creek Group dominate. To the south the Takla Group is intruded by the Cretaceous Germansen batholith.

Locally, the area is underlain by volcanics and sediments of the Upper Triassic Plughat Mountain Formation (Takla Group). Tinnecha Hill, to the southeast of the occurrence, is mainly porphyritic hornblende basaltic andesite. Volcanics directly surrounding the occurrence are silicified andesites which are slightly calcareous and weakly metamorphosed by the Germansen batholith. Minor amounts of recrystallized dark grey to black limestone (in part dolomitic) are found just to the south of the trenched gossan zone.

This occurrence includes a 1.5-metre hand trench that follows a 1.3-metre wide zone of gossan (in part silicified) found approximately 400 metres to the south of the mineralized quartz vein. The gossan zone is a 1.3 metre wide, limonitic shear that is made up of malachite-stained quartz pods and oxidized fault gouge. It strikes 080 degrees and dips vertically. The quartz vein is parallel to the shear, is malachite stained and contains pyrite with trace amounts of chalcopyrite and tetrahedrite. It is less than 0.5 metre in width and a grab sample of this vein analysed 450 grams per tonne silver, 0.53 per cent copper, 0.11 per cent zinc, 0.098 per cent lead, 0.24 per cent antimony with trace amounts of gold (0.026 grams per tonne) (Open File 1989-12, sample DME88-26-6-1).
