Location and accuracy The Moose Creek occurrence is located in the NE1/4 sec. 15, T. 10 S., R. 7 W., Fairbanks Meridian. There are several mineral occurrences. At least one was known prior to 1918, and several were drilled in the mid-1990's. The coordinates are approximately located in the center of an area a mile or more across that has been prospected. The occurrence is locality 39 of Cobb (1972 [MF 410]).

Geologic setting

Geologic description

Before 1918, quartz porphyry intrusives were noted near the head of Moose Creek and placer gold found in the stream course that cut through them (see FB127). A specimen of oxidized schist from a claim at the head of the creek contained arsenopyrite and pyrite; an assay determined the presence of gold (Overbeck, 1918, p. 350). In 1993, AMAX Gold drilled several intrusions in upper Moose Creek that showed signs of gold mineralization. Apparently the results were not encouraging, and they did not return in subsequent years (Donald Grybeck, field observations, 1994).

Production and reserves

Workings or exploration At least one sample that contained gold was collected in the area prior to 1918. In 1993, AMAX Gold drilled several intrusions in upper Moose Creek that showed signs of gold mineralization. Apparently the results were not encouraging, and they did not return in subsequent years (Donald Grybeck, field observations, 1994).
Indication of production None
