Location: The location given by Cobb (1979 [OFR 79-238]) for this occurrence is north of the Chistochina Glacier and southwest of Mount Kimball. The location is an arbitrary point in the NW1/4 section 9, T. 20 S., R. 16 E., Fairbanks Meridian. The accuracy is undetermined; the actual location may be several or more miles away.
Geology: A grab sample of highly stained and pyritized argillite from this location contained 0.02 ounce of gold per ton and traces of silver (Rose, 1967). The grab sample was of argillite from the Mankomen Formation of Permian age (Cobb, 1979 [OFR 79-238]).
Workings: Only one grab sample of highly stained and pyritized argillite was taken from this location.
