Geologic setting

Geologic description

This occurrence consists of maroon, felsic schist that contains 5% oxidized sulfides (Dillon and others, 1981 [AOF 133B]). The sulfides are principally pyrite and sphalerite, and possibly galena. A rock sample contains 350 ppm Zn. The rocks in the area are Devonian, Skajit Limestone, a few miles south of the Earnie Lake pluton (Dillon and others, 1986). No other information is available.
