The Farmer 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.

Alterations

Alteration Type: L
Alteration Text: Below the hanging wall, there is 4 inches of iron-stained quartz, followed by 14 inches of crushed, bluish schist, followed by 2 feet of iron-stained fault breccia made up of fragments of schist and quartz (Hill, 1933, p. 122-123).

Comments

Comment (Workings): Workings / Exploration = By 1914, an inclined shaft had been sunk 60 feet on the vein but the work was abandoned because the results were not encouraging (Chapin, 1914 [B 592-J, p. 352]).

Comment (Deposit): Model Name = Schist-hosted gold-quartz vein

Comment (Geology): Geologic Description = Visible gold and pyrite occur in a north-trending, apparently lenticular vein in schist (Smith, 1913 [B 525 p. 198]). The schist dips 40 degrees east and is cut by many small faults. The vein is oriented N. 25 E., 52 W. and has a hanging wall of quartz-mica schist (Hill, 1933). Below the hanging wall, there is 4 inches of iron-stained quartz, followed by 14 inches of crushed, bluish schist, followed by 2 feet of iron-stained fault breccia made up of fragments of schist and quartz (Hill, 1933, p. 122-123). A sample taken across 4 feet assayed $7.06 in gold per ton (0.34 ounce of gold per ton) (Hill, 1933, p. 123). By 1914, an inclined shaft had been sunk 60 feet on the vein, but the work was abandoned because the results were not encouraging (Chapin, 1914 [B 592-J, p. 352]).

Comment (Production): Production Notes = There is no record of the amount of gold that was produced.

Comment (Reference): Primary Reference = Hill, 1933

Comment (Exploration): Status = Inactive
