Geologic setting

Geologic description

This occurrence consists of a 20-inch-thick quartz vein which strikes northwest and dips southwest, approximately parallel to the Bear (KD003) and Dan (KD004) veins. It crops out northeast of the Dan and cuts Cretaceous metasedimentary rock. The vein carries arsenopyrite, pyrite, galena, and gold. Acidic dikes occur in the vicinity.
