The Patella showing is an east-northeast trending yellow-brown weathering, carbonate vein, at least 100 metres long, averaging 0.55 metre wide and containing up to 15 per cent sphalerite and galena. This vein is hosted in intermediate to mafic volcanic rocks within several hundred metres to the west of the Ophir Break fault zone. The area is mapped as undivided Mississippian volcanic rocks of the Stikine Assemblage. Contact with a Late Cretaceous quartz monzonitic pluton (formerly the Ramtut stock) occurs to the immediate west of the vein area. The host volcanic rocks are reported to be bedded tuffs and augite porphyry.

The vein structure is reported to intersect a north-south diorite-volcanic contact approximately 100 metres to the west. Skarn-like mineral assemblages are noted in altered limy tuffaceous interbeds within the volcanics. The best result out of 9 rock samples taken on the vein in 1994 was 0.15 gram per tonne gold, 38.0 grams per tonne silver, 0.84 per cent lead, >1 per cent zinc and 1.13 per cent mercury (Assessment Report 23621).

The Patella vein was discovered by North American Metals Corp during 1994 reconnaissance work on the Nie-Misty property. Mapping and sampled of the showing ensued the discovery. Please refer to Nie (104K 081) for details of a common work history.
