Geographic coordinates

Geographic coordinates: -148.00294, 64.84966 (WGS84)
Relative position The Eva Creek mine is located in secs. 5 and 8, T. 1 S., R. 2 W., Fairbanks Meridian. Eva Creek, which joins Ester Creek about a half-mile east of the town of Ester, has been mined for at least a half-mile above its mouth, and its lower workings merge into the working on Ester Creek (FB034). The mine is locality 44 of Cobb (1972 [MF 410]).

Comments on the geologic information

  • Geologic Description = In 1911, rich gravel was found on Eva Creek (Ellsworth, 1912, p. 243). In 1912, the creek had produced about one-half million dollars worth of gold or 24,000 fine ounces, mostly from drift mines (Ellsworth and Davenport, 1913, p. 209). Mining continued in 1913 and 1915 (Chapin, 1914, p. 359; Brooks, 1916 [B 642, p. 59]). A gold fineness value of 795.4 was reported (Glover, 1950). Although there is little detailed record of mining on Eva Creek after 1915, it has been mined periodically since, notably in the lower half-mile where a wide swath of the valley has been mined with mechanical equipment from the surface in recent years (J.R. Guidetti Schaefer, personal observation, 2000).

Comments on the production information

  • Production Notes = By 1912, a year after gold was discovered, the creek had produced about one-half million dollars worth of gold, or 24,000 fine ounces (Ellsworth and Davenport, 1913, p. 209). There has undoubtedly been production since, but there is no information available of the amount.

Comments on the workings information

  • Workings / Exploration = Placer mining took place in 1911-13 and 1915 (Ellsworth, 1912, p. 243; Chapin, 1914, p. 359; Brooks, 1916 [B 642, p. 59]). In 1929, a drift operation was reported (Wimmler, 1929, p. 191). Although there is little detailed information recorded of mining on Eva Creek after 1915, it has been mined periodically since, notably in the lower half-mile where a wide swath of the valley has been mined from the surface in recent years with mechanical equipment (J.R. Guidetti Schaefer, personal observation, 2000).
