The Frisco occurrence is located along the south side of Frisco Creek in rugged terrain approximately 35 kilometres northeast of Terrace. Access to the property is gained by all-weather road northward from Terrace along the Skeena River valley, then along a forestry road about 20 kilometres southeastward up the valley of Legate Creek (ca. 1988). A trail established in the early 1900s leads to showings on the property, which are at and above timberline.
Andesites of the Jurassic Hazelton Group are intruded by quartz porphyry sills up to 30 metres wide. Disseminations and stringers of chalcopyrite and bornite occur above the sills over a 30 metre distance. A 12 metre wide mineralized zone strikes east and dips 30 degrees south. A grab sample from sorted ore assayed 11.62 per cent copper and 398 grams per tonne silver (Geological Survey of Canada Memoir 212).
About 300 metres to the east, a quartz vein, 15 to 60 centimetres wide, is exposed for 30 metres along the hangingwall side of another quartz porphyry sill intruding the andesite. The vein is sparsely mineralized with chalcocite and tetrahedrite. A 10-centimetre sample across the vein assayed 2489 grams per tonne silver, 5.2 per cent copper and 0.69 gram per tonne gold (Minister of Mines Annual Report 1928).
The Frisco showing was sampled in 1988 with a grab sample assaying 0.18 gram per tonne gold, 301.4 grams per tonne silver, 6.1 per cent copper, 1.9 per cent lead and 0.2 per cent zinc (Assessment Report 18475).
In 1917, 9 tonnes of ore was shipped from this property. From this ore, 15,552 grams of silver and 2903 kilograms of copper were recovered.
In 1988, Cedarmine Resources Inc. conducted a short geological exploration program on the Top claim which covers the Frisco and M&K (103I 062) showings.
