Geologic information

Identification information

Deposit ID 10001909
MRDS ID A012739
Record type Site
Current site name Coffee Creek (the upper portion)

Geographic coordinates

Geographic coordinates: -164.80642, 65.30125 (WGS84)
Relative position Coffee Creek crosses the Nome-Taylor road at about mile 74 and again at about almost mile 75. The upper part of Coffee Creek that has been placer mined is 5,000 feet upstream from the road crossing at mile 74. About 1,500 feet of the drainage was open-cut mined at this location (Sainsbury and others, 1969). This is locality 43 of Cobb (1972; MF 417).

Comments on the geologic information

  • Geologic Description = This small area of placer workings is primarily known from the mapping of Sainsbury and others (1969). Early references to a residual gold placer near the head of Coffee Creek (Collier and others, 1908; Cobb, 1975, OFR 75-429) are for the Wonder Gulch tributary (BN005) and not this location. Thick muck deposits are present on Coffee Creek and bedrock is not exposed in this area. Bedrock here is expected to be low grade, Lower Paleozoic metasedimentary rocks like those exposed on lower parts of Coffee Creek and nearby uplands (Till and others, 1986).
  • Age = Quaternary

Comments on the workings information

  • Workings / Exploration = Open-cut placer mining, probably dozer and sluice operations, took place along 1,500 feet of the active drainage.
