Location and accuracy	This unnamed occurrence is located near the west bank of Cheeneetnuk River at an elevation of 850 feet (259 m) in the SW1/4 sec. 27, T. 23 N., R. 32 W., of the Seward Meridian. The occurrence corresponds to map number 122 of Gilbert (1981); his station no. 77WG21.

Geologic setting

Geologic description This occurrence is a highly anomalous stream sediment sample taken at the intersection of an unnamed, second order stream with Cheeneetnuk River. The stream drains a mid-Tertiary granite pluton; its associated, mineralized contact zone may be related to several other occurrences in the area (MG017, MG018, MG020, MG021). The stream sediment sample contained 43.3 grams/tonne silver, 322 ppm copper, and 19 ppm molybdenum (Gilbert, 1981).
