Location and accuracy The exact location of this prospect is uncertain. It is probably at an elevation of about 1,100 feet on a north tributary to Jones Creek in the SW1/4 section 22, T. 27 N., R. 23 W., of the Fairbanks Meridian.

Geologic setting

Geologic description

Almost no information is available on this property except that reportedly it is a stratiform Cu-Zn occurrence in an area whose geology and geochemistry is similar to that in the Ambler District to the west (Grybeck, 1977). Regional geologic mapping indicates that the rocks in the vicinity of this occurrence are Devonian, Ambler metavolcanic rocks (Dillon and others, 1986). Thirty-six lode claims were staked in 1975 (Grybeck, 1977) and 3 holes were drilled on the prospect in the 1970s by Anaconda Minerals (Kurtak and others, 2002).
