Comments on the geologic information

  • Geologic Description = This unnamed creek and its headwater tributaries drain the southeast flank of Nagotligageivik Mountain. Fechner (1988) collected four placer samples in the upper part of the drainage. They contained 0.0002 to 0.0010 ounce of gold per cubic yard, and heavy-mineral concentrate from one sample contained Pt and Pd values (Fechner, 1988, p. 60). The gold fineness ranged from 424 to 816. A reconnaissance of the nearby mountain found only barren chert. The gold may be reworked from glacial deposits.
  • Age = Holocene.
