The Patmore occurrence is located on the lower north-northwestern slope of Mount Knauss, approximately 750 metres south of Fiddler Creek.
The area is underlain by Lower Jurassic volcanics of the Hazelton Group and Upper Jurassic sediments of the Bowser Lake Group. The strata are comprised of laminated argillites, bedded tuffs and interbedded andesite flows.
Locally, Cretaceous quartz diorite sills and dikes cut argillites and tuffs of the Jurassic to Cretaceous Bowser Lake Group. The intrusives contain quartz veins mineralized with galena, sphalerite and lesser pyrite and chalcopyrite.
The No. 1 showing is located at 778 metres elevation and contains quartz veins averaging 15 centimetres in width and 15 metres in length. A representative sample assayed 4.1 grams per tonne gold, 78.2 grams per tonne silver, 1.00 per cent lead and 1.05 per cent zinc (Geological Survey of Canada Memoir 212).
The No. 2 showing, 365 metres to the west, occurs in a quartz diorite sill within argillites that strike east and dip 40 degrees north. A 15 centimetre channel sample assayed 4.8 grams per tonne gold, 91.9 grams per tonne silver and 2.92 per cent lead (Geological Survey of Canada Memoir 212). Additional mineralized exposures are reported 60 metres down slope and to north of the No.2 showing.
In 2006, a sub-crop float sample (AGP6-01) of pyrite and galena bearing quartz vein, from above the No.1 showing at an elevation of 850 metres, assayed 1.2 grams per tonne gold, 112 grams per tonne silver, and 2.75 per cent lead (Assessment Report 29216).
In 1981, Canamco Resources completed a program of airborne geophysical surveys, totalling 206 line-kilometres, on the area as the Top 1-8 claims. In 2004 and 2006, Argonaut Resources completed programs of prospecting and geological mapping on the area as the Coffee and Cup claims.
