The Red 12, 16 occurrence is located 4 kilometres east of Treble Mountain within the southern limits of the extensive Cambria Icefield, about 19 kilometres southeast of Stewart.
Weak to strong quartz-carbonate stockworks up to 5 metres in width are present in locally carbonate altered, maroon andesitic volcanics of the Jurassic Hazelton Group. Narrow zones of galena, sphalerite, pyrite and occasionally chalcopyrite occur along some of the stockwork stringers. Tetrahedrite is also present in trace amounts in some of the quartz-carbonate. A grab rock sample (ERK-731) from a carbonate-altered zone 2-3 metres wide and containing 2-15 centimetre wide sulphide stringers analyzed 3.3 per cent lead, > 10,000 parts per million tungsten, > 1000 parts per million cadmium, 1024.7 grams per tonne silver, 0.12 per cent copper, 9.68 per cent zinc and 0.19 per cent antimony; the zone strikes 060 degrees and dips 80 degrees north? (Assessment Report 23937).
North of the maroon volcanics, hornfelsed augite porphyry basalt contain fine-grained pyrrhotite in amounts varying from 1-4 per cent. To the east, medium grained granodiorite dikes intrude a sequence of basalts and argillites. These dikes strike at approximately 320 degrees. Fine, disseminated pyrrhotite comprises 2-3 per cent of the rock. Numerous narrow carbonate veinlets are present in the area of the dike intrusions.
In 1994, Teuton Resources Corp. conducted work on the Red 12 and 16 claims as part of a larger program covering several Stewart area properties; a total of 26 samples were taken for analysis.
