|Location and accuracy||No Man Creek is a south tributary to the Casadepaga River. Its mouth is about 1,000 feet downstream from the mouth of Big Four Creek (SO066). This is locality 69 of Cobb (1972, MF 445; 1978, OF 78-181).|
Geologic descriptionA little mining by one person took place here in 1907 (Smith, 1910). The mining was probably along the lower part of the creek where it crosses and reworks terrace deposits of the Casadepaga River.
|Geologic map unit||(-164.168621311413, 64.9082626019861)|
|Mineral deposit model||Placer Au-PGE (Cox and Singer, 1986; model 39a).|
|Mineral deposit model number||39a|
|Age of mineralization||Quaternary; the numerous incised terraces along the Casadepaga River indicate that more than one cycle of erosion and deposition has developed placer deposits in the area. The low elevations of 170 to 270 feet along the first 11 miles of the river, suggest that Quaternary sea level fluctuations could have influenced placer development.|
|Workings or exploration||Small-scale mining by hand is all that is indicated for this locality.|
|Indication of production||Yes; small|
