Location: The Farmer mine is located in the NE1/4NE1/4 sec. 36, T. 1 N., R. 3 W., Fairbanks Meridian. The workings are at an elevation of about 1,900 feet near the head of the west fork of Ready Bullion Creek. This mine is locality 9 of Cobb (1972 [MF 410]).
Geology: 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]).
Workings: 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]).
Alteration: 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).
Production: There is no record of the amount of gold that was produced.
