Location and accuracy This occurrence is on McKinley Creek, approximately 7.5 miles northwest of the junction of McKinley Creek and John River, at an elevation of about 1,850 feet. The occurrence is the site of sample 20 of Dillon and others (1981 [AOF 133B]). The location is accurate.

Geologic setting

Geologic description

This occurrence is based on a float sample of fuchsite-quartz dolomite that contains about 1% disseminated arsenopyrite or galena, as well as pyrite cored by chalcopyrite (Dillon and others, 1981; sample 20 [AOF 133B])). A sample of this rock contains as much as 1,500 ppm arsenic, 200 ppm lead, 1,500 ppm chromium, and 50 ppm nickel. Sphalerite in float is also reported in an area about a mile to the west but the exact location is uncertain. The rocks in the area consist mostly of Devonian, Skajit Limestone (Dillon and others, 1986).
