| The Anahim Lake map area, underlain to the west by the Coast belt and
to the east by Mesozoic and Tertiary volcanic and sedimentary rocks of the Intermontane
belt, contains 16 recorded mineral occurrences. A hybrid zone along the eastern
margin of the belt contains elements of both tectonic belts. In this zone Mesozoic rocks
have been incorporated into the plutons and are overlain by Tertiary volcanic rocks. The
degree of metamorphism and deformation of the Intermontane belt supracrustal rocks
increases towards the Coast belt. Copper and molybdenum mineralization
occur in diatreme breccia zones and disseminated along joint and fracture planes in
intrusive rocks. Minor precious metal mineralization has been reported in this area. Of
note, is the epithermal mineralization in Ootsa Lake volcanics on the Oboy
(093C 015) prospect.
