Geologic setting

Geologic description

The host rock of this prospect is graywacke of the Tertiary Orca Group. The mineralization consists of quartz-chalcopyrite stringers within a 3 foot wide shear zone. The strike and dip if the mineralization is unknown. The graywacke strikes northeast and dips 50 to 70 to the southeast. A 3 foot chip wide chip sample of the mineralization contained 1.7 percent Cu and 8.5 ppm silver (Nelson and others, 1980).
