|Location and accuracy||This prospect is within Jack Bay State Marine Park; it is on the west-facing slope of the ridge in the center of the east side of the park. It is at an elevation of about 400 feet in the SE1/4 section 1, T. 10 S., R. 8 W., of the Copper River Meridian. This prospect is probably located to within one-quarter mile. It is locality 38 of Cobb and Matson (1972) and locality 30 of Winkler and others (1981 [OFR 80-892-B]).|
Geologic descriptionSlate inclusions in greenstone of the Valdez Group contain pyrite, pyrrhotite, chalcopyrite and sphalerite (Johnson, 1919). The deposit was explored by a 25-foot adit. It may be a submarine volcanogenic deposit, similar to the deposit at the Midas mine (VA103).
