GEOLOGY


The C2 zone mineralization occurs west of the Stonehouse Gold deposit along the east side of the Craig River within a prominently sheared contact zone. This pyritized sheared zone lies between the contact of an Upper Triassic to Lower Jurassic volcanic/ sedimentary sequence that has in part been correlated to the Jurassic Hazelton Group, Unuk River Formation. Some of these altered, strati- fied rocks may be correlative to upper members of the Triassic Stuhini Group. The stratified Jurassic-Triassic rocks are intruded by inter- mediate to felsic stocks and plutons of Jurassic and younger age that are related to the Coast Plutonic Complex.

Alteration includes pyritization, silicification and carbonati- zation as well as k-feldspathization. Mineralization within the C2 zone consists mainly of pyrite with minor chalcopyrite, sphalerite and galena associated with a prominent shear. Assays from this area average about 3.4 grams per tonne gold. In 1984, a sample of pyritic mataerial taken from the sheared rock at location 83, assayed 4.8 grams per tonne gold, 50.06 grams per tonne silver, 0.7 per cent lead and 0.3 per cent zinc.
