The Red 10, 13 occurrence is located in a series of nunataks exposed along a northwest axis in the Cambria Icefield, about 18 kilometres south-southeast of Stewart.
In the showing area, along the western flank of Mount Trevor, Lower Jurassic Hazelton Group volcanics are intruded by feldspar porphyry dikes. Just above the Bromley Glacier, black, siliceous, well-bedded siltstones are in contact with rhyolites to the west. The rhyolite sequence consists of grey, thinly bedded tuffs with 1 per cent pyrite along fractures. Narrow horizons of pinkish felsic fragmental rock, generally carbonate altered, are present with the rhyolite sequence. Where altered, the felsic rocks contain up to 3 per cent pyrite, both as coarse cubes and fracture filling.
A grab sample (ERK-533) from a northerly striking quartz stringer, up to 4 centimetres wide, mineralized with coarse chalcopyrite and minor tetrahedrite analyzed 1.74 per cent copper and 17.8 grams per tonne silver (Assessment Report 23884).
In 1994, Teuton Resources Corp. collected 45 reconnaissance geochemical rock samples on the Red 10, 13, 18 and 19 claims.
