Geologic information

Identification information

Deposit ID 10001920
MRDS ID A012753
Record type Site
Current site name Boulder Creek (= Grouse Creek)

Geographic coordinates

Geographic coordinates: -162.22328, 65.02936 (WGS84)
Relative position The original reference for this occurrence (West, 1953) describes it as on Grouse Creek whch is the same as Boulder Creek (BN089) on the current USGS topographic map of the area (Bendeleben A-1 quadrangle). The current topographic map shows Grouse Creek to be the northeast tributary to Boulder Creek and it was this location that was identified as locality 57 by Cobb (1972; MF 417; 1975; OFR 75-429). This prospect is here taken to be on Boulder Creek as shown on the current topographic map of the area. Boulder Creek is a small north tributary to the middle Tubutulik River.

Comments on the geologic information

  • Geologic Description = West (1953) noticed the remains of old placer mine workings on this creek, as well as coal-bearing rocks in its headwaters, and collected a slightly radioactive heavy-mineral concentrate containing ilmenite, magnetite, garnet, and sphene. The Death Valley sandstone uranium deposit (BN089) is now known to be in the headwaters of this stream (Dickinson and others, 1987). The upper part of Boulder Creek approximately coincides with the contact between the Cretaceous Darby pluton to the west and early Eocene continental sediments and basalt to the east.
  • Age = Quaternary

Economic information about the deposit and operations

Development status Prospect
Commodity type Metallic

Comments on exploration

Mining district

District name Koyuk

Comments on the workings information

  • Workings / Exploration = Surface placer mine workings have been noted here (West, 1948) but their success in recovering gold is uncertain.
