Location and accuracy The placer mine is in the main flood plain of the Chistochina River about 0.6 mile north of the mouth of Slate Creek. It is in the NW1/4SW1/4 section 15, T. 20 S., R. 15 E., Fairbanks Meridian. The location of the mine is shown by Rose (1967); it corresponds to locality 12 on figure 6 of Cobb (1979 [OFR 79-238]). The location is accurate within about 0.1 mile.

Geologic setting

Geologic description

Placer gold and some platinum-group elements (PGE) and scheelite occur in Holocene outwash gravels of the Chistochina River in a part of the river's course that was covered by ice in 1900 (Rose, 1967; Cobb, 1979 [OFR 79-238]). The gold, PGE, scheelite, and possible magnetite probably occur in outwash or river-bar-type deposits.
