Eva Creek

The Eva Creek is a gold mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Geology): 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).

Comment (Workings): 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).

Comment (Exploration): Status = Active?

Comment (Production): 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.

Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)

Comment (Reference): Primary Reference = Cobb, 1976 (OFR 76-662)

Comment (Geology): Age = Quaternary placer.
