The Asitka River occurrence is located approximately 5 kilometres southwest of the mouth of Quenada Creek (Geological Survey of Canada Memoir 251, page 63).

The area is underlain by the Upper Triassic Dewar Formation (Takla Group) which consists predominantly of tuffs, sandstones, and argillites with minor limestones and breccia. Sphalerite and chalcopyrite occur in a calcite and quartz vein. The vein is 0.15 metre wide and has been exposed for 0.61 metre. The Geological Survey of Canada collected a select sample from this vein sometime prior to 1948, when Memoir 251 was published. The sample assayed trace gold, 57.25 grams per tonne silver, 14.36 per cent zinc and 5.41 per cent copper (Geological Survey of Canada Memoir 251, page 63).
