Identification information

Deposit ID 10307977
Record type Site
Current site name Unnamed (ridge between Butterfield and upper Bangor Creeks)

Geographic coordinates

Geographic coordinates: -165.51749, 64.68938 (WGS84)
Relative position This occurrence is at an elevation of about 1,250 feet on the ridge crest between the headwaters of Bangor and Butterfield Creeks in the northwest Nome C-2 quadrangle. Mining claims were located on intensely deformed quartz-rich schist, probably before 1920. Claim locators used metamorphic quartz rods as much as 6 feet long and 6 inches in diameter as claim markers. The location is accurate within about 1,000 feet.

Comments on the geologic information

  • Geologic Description = This occurrence is at or near the crest of an antiform where intensely deformed schist contains weakly mineralized quartz, including quartz rods (Kennecott Exploration Company, written communication, 1992). The quartz rods and linear elements in the schist plunge to the north-northwest. The area was apparently prospected in the early years of the Nome district, probably before 1920; quartz rods were used as claim posts. Quartz and schist from the site contain as much as 0.02 ounce of gold per ton and hundreds of parts per million arsenic. The occurrence is of interest because it may indicate pre-metamorphism gold mineralization or mineralization during a ductile stage of metamorphism. In either case, the mineralization is older than the widespread low-sulfide Au-quartz veins of the Nome district.
  • Age = Mineralization either predates regional metamorphism or took place during a ductile stage of deformation, possibly mid-Cretaceous.
