Location and accuracy This approximately located occurrence is on the Alaska Peninsula, about 4.2 miles north of upper Dorenoi Bay (Christie, 1974, color anomaly 75; MacKevett and Holloway, 1977, locality 24; Wilson and others, 1988, locality 24). The map site is at an elevation of 1,100 feet, in the SE1/4 of sec. 35, T. 51 S., R. 72 W., of the Seward Meridian. The location is accurate to within 3 miles.

Geologic setting

Geologic description

The area of this site is marked by a 1- by 2-mile color anomaly (Christie, 1974, number 75) in the late Eocene to early Oligocene Stepovak Formation (Wilson and others, 1995). The bedded rocks are intruded by several plutons. Christie described the occurrence as sparse calcite veins and vein breccias containing a trace of pyrite. He collected six silt samples that contained as much as 0.01 ppm gold, 1.8 ppm silver, 70 ppm copper, 102 ppm zinc, and 4 ppm molybdenum.
