Metallogeny of the region adjacent to the northern part of the Cassiar Batholith, Yukon Territory and British Columbia

The northern part of the Cassiar region, in the Yukon British Columbia boundary country between Watson Lake and Teslin, is an area of extraordinary structural complexity, and of numerous and varied mineral occurrences . The Cassiar asbestos mine is the only major producer but gold is still being won from the old Mc Dame placer field. Several of many small silver-lead-zinc deposits and two of the molybdenite deposits have been intensively explored in recent years. Tungsten deposits of two types are of possible economic interest. Of special metallogenic interest are the numerous minor beryllium and tin occurrences in the district.
