|Location and accuracy||The Little Moose Creek mine is located in secs. 20 and 21, T. 10 S., R. 7 W., Fairbanks Meridian. Over the years, placer operations have taken place at various locations along Little Moose Creek, and the coordinates are approximately the mid-point of the creek. The mine is locality 63 of Cobb (1972 [MF 410]).|
Geologic descriptionThe Little Moose Creek basin is underlain mainly by quartz-orthoclase-sericite schist of the California Creek Member of the Totatlanika Schist (Wahrhaftig, 1970 [GQ-810]). Gold is found in stream gravel that is approximately 2 to 4 feet thick along the lower mile of the creek above the confluence with Moose Creek (Maddren, 1918). Scarce scheelite was found in placer concentrates (Joesting, 1943 [ATDM Pamph. 2, p. 20[). Glover (1950) reported that the gold is 860 fine.
