|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 descriptionPlacer 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.
