The Fair or Red Mountain showing is underlain by well-bedded crystalline limestone with interbedded cherty argillite and minor quartzite, of Ordovician(?) to Devonian(?) or younger age. These sediments may be in part overlain by Norian (Upper Triassic) limestones with quartz veins. Locally brecciated, cherty tuffaceous beds with disseminated to massive pyrite and pyrrhotite, pillow basalt, argillite, and associated intrusives overlies the Paleozoic sediments. Epidote-diopside skarn occurs near contacts between lime- stone and hornblende-feldspar porphyry dykes, and is mineralized by irregular pods of galena, sphalerite, chalcopyrite, pyrite and pyrr- hotite.
In the southern portion of the claim group, drilling has inter- sected narrow skarn zones in white "porcellanite" containing dissemi- nated and fracture-filling pyrrhotite, and a 0.5 metre wide quartz vein with minor chalcopyrite and sphalerite. Shear zones in the volcanics contain quartz, sphalerite, galena, and pyrrhotite, while diamond drilling intersected 5 centimetre quartz veinlets with arsenopyrite. A 20 centimetre drill core sample assayed 4.1 per cent lead, 2.2 grams per tonne gold, 4.5 grams per tonne silver, and 0.55 per cent zinc.
