Location: The Silver Dollar mine is located in the NE1/4 SE1/4 sec. 36, T. 1 N., R. 3 W., Fairbanks Meridian. This mine is on the west side of Ready Bullion Creek; it is at an elevation of about 1,300 feet about 0.9 mile south of the top of Ester Dome. The mine is included in locality 5 of Cobb (1972 [MF 410]).
Geology: Gold has been mined from a quartz vein that strikes N. 30 E. and dips 68 SE (Hill, 1933, p. 127). This 5-foot-wide vein consists mainly of crushed quartz with some altered schist. A sample across the full width of the vein assayed $9.63 in gold per ton (about 0.46 ounce of gold per ton). When visited by Hill in 1931, there was about 10 tons of ore left on the dump, a grab sample of which assayed $74.76 in gold per ton (about 3.6 ounces of gold per ton). By 1931, about $4,000 worth of gold (about 193 ounces of gold) was mined from the shaft and tunnel at an elevation of about 1,300 feet or about 150 feet above the creek. Southwest of the upper tunnel there were several shallow shafts, all of which were caved when visited by Hill in 1931. For a discussion of the Silver Dollar/Ready Bullion prospect explored in the 1990's by Placer Dome Exploration, Inc., see the Ready Bullion prospect (FB024).
Workings: By 1931, about $4,000 worth of gold (about 193.5 ounces) was mined from the shaft and tunnel, which are at an elevation of about 1,300 feet or about 150 feet above the creek (Hill, 1933, p. 127). Southwest of the upper tunnel there were several shallow shafts, all of which were caved when visited by Hill in 1931. A tunnel started from a point near the creek level was driven S. 65 W. for 515 feet (Hill, 1933, p. 128).
Alteration: Schist is altered.
Production: By 1931, about $4,000 worth of gold (about 193.5 ounces of gold) had been mined (Hill, 1933, p. 127).
Reserves: Silverado Gold Mines, Ltd. reported a probable resource of 1,232,636 ounces of gold on their Ready Bullion/Silver Dollar property (Silverado Gold Mines, Ltd., Ester Dome project web site, February 17, 2000; http://www.silverado.com). This property includes this site and the Ready Bullion mine (FB024).
