Comments on the geologic information

  • Geologic Description = By 1913, several tons of ore had been mined from an 18-inch- to 4-foot-wide vein that carried approximately 1.2 ounces of gold per ton (Smith, 1913 [B 525, p. 166]). The gold-quartz vein contained very few sulfides and was oriented N. 50 E., 60 NW. (Chapin, 1914,B[ 592, p. 329-330]). The footwall is a zone of schist, 3 feet wide, that contains small quartz stringers; gold could be panned from most random samples of the quartz (Chapin, 1914 [B 592-J]). This mine lies on the western edge of a Cretaceous granite that intrudes two units of the Fairbanks Schist that are composed of (1) quartz-muscovite schist, quartzite, and chlorite-quartz schist, and (2) amphibolite, magnetite-rich biotite schist, quartz schist, and marble (Newberry and others, 1996). By 1931, the workings were inaccessible, but the material on the dumps was examined and consisted of brecciated schist partly cemented by quartz (Hill, 1933).

Mining district

District name Fairbanks

Comments on the production information

  • Production Notes = In 1911, twenty tons of ore, with a grade of 1.21 ounces of gold per ton, were mined from a 38-foot shaft on the American Eagle claim. There is no record of production after 1913 when several tons of ore were mined (Smith, 1913 [B 525]).

Comments on the workings information

  • Workings / Exploration = In 1914, an inclined shaft was 60 feet deep (Chapin, 1914, B 592-J, p. 329-330). By 1931, the workings were inaccessible (Hill, 1933).
