|Location and accuracy||This prospect is at an elevation of 4,300 feet on the east side of the east fork of stream(s) in Broxson Gulch, in the SW1/4NW1/4 section 5, T. 19 S., R. 9 E., Fairbanks Meridian. The prospect corresponds to locality 11 in figure 2 of Rose (1965).|
Geologic descriptionThe rocks at this occurrence consist mainly of serpentine and limestone. Copper-stained and strongly iron stained rocks occur in float at the site, but copper-bearing bedrock has not been reported (Rose, 1965). The source of the float may be Upper Triassic mafic or ultramafic rocks that occur in the area (Nokleberg and others, 1982).
