Geographic coordinates

Geographic coordinates: -156.67344, 66.97954 (WGS84)
Relative position The Lynx Creek placer mine is about 1.2 mile above its confluence with Kogoluktul River. The deposit extends from NE1/4, section 9 to S1/2 section 3, T. 18 N., R. 10 E., of the Kateel River Meridian. The main workings were in sections 9 and 10. The location is plotted from description in Bundtzen and others (1986) and Mayfield and Grybeck (1978), location 33.

Comments on the geologic information

  • Geologic Description = The upper portion of Lynx Creek is underlain by lower Paleozoic mica schist and the lower portion of the creek is underlain by lower to mid Paleozoic granite gneiss. Placer gold occurs mostly on the mica schist bedrock beneath eight feet of overburden. The overburden consists of two feet of vegetation and muck and six feet of gravel. The gravel is up to one inch in diameter with numerous small boulders. The ground is thawed and bedrock is soft and decomposed. One to 2 feet of bedrock are mined with the gravel. The gold is of two types. About half is in small nuggets and the rest is fine, rounded grains. It was worth about $17.20 per ounce in 1931. The ground yielded between $0.273 to $0.375 per cubic yard of material. No gold has been found on the gneiss bedrock (Reed, 1931).
  • Age = Quaternary.
