|Location and accuracy||This approximately located occurrence is north of Lumber Bay on the Alaska Peninsula, between Balboa Bay and Unga Strait (MacKevett and Holloway, 1977, locality 19; Wilson and others, 1988, locality 19). The map site is at an elevation of about 550 feet, in the NW1/4 of sec. 3, T. 54 S., R. 73 W., of the Seward Meridian. The location is accurate to within 1 mile.|
Geologic descriptionThis occurrence is in late Miocene volcanic rocks (Wilson and others, 1995). It is described as an altered zone in Tertiary rocks (Christie, 1974; MacKevett and Holloway, 1977). The alteration is argillic, possibly of fumarolic origin. The main commodity herein is speculated to be gold, based on its association with altered zones elsewhere in Tertiary volcanic rocks.
