Geologic setting

Geologic description

This occurrence consists of magnetite(?) in Jurassic quartz diorite (Detterman and Reed, 1980). Immediately north and west of The Cone, the quartz diorite intrudes the Permian(?) to Jurassic Kakhonak metamorphic complex and Upper Triassic Cottonwood Bay Greenstone. Locally, the quartz diorite includes phases as mafic as diorite. Numerous claims were staked in the area, but there is no information about the claims other than that they appear to have been located for a magnetic iron deposit.

Production and reserves

Workings or exploration Exploration probably is limited to reconnaissance geologic mapping and collecting surface samples. Numerous claims were staked in the area (U.S. Bureau of Mines, 1973; MacKevett and Holloway, 1977).
