Location and accuracy	The Ready Bullion Creek mine is located in the W1/2 sec. 6, and N1/2 sec. 6, T. 1 S., R. 2 W., Fairbanks Meridian. The coordinates given are for the mine marked along Ready Bullion Creek on the Fairbanks (D-3) SE topographic map, the site of recent mining. However, Ready Bullion Creek has been extensively mined from its mouth for at least a mile upstream. This mine is locality 44 of Cobb (1972 [MF 410]).

Geologic setting

Geologic description Ready Bullion Creek drains an area underlain by quartz-muscovite schist, quartzite, and chlorite-quartz schist of the Fairbanks Schist and amphibolite and biotite schist of the Muskox sequence (Newberry and others, 1996). Placer gravels were reported to be as much as 80 feet deep (Prindle and Katz, 1913, p. 110). The creek was mined from 1907 to 1914 with production well over 25,000 ounces of gold (Cobb, 1976 [OFR 76-662]). Ready Bullion Creek has been mined to the present however there is little record of the details. Recent mining has been concentrated on upper Ready Bullion Creek, notably at the site shown on the current Fairbanks (D-3) SE topographic map.

Production and reserves

Workings or exploration	The creek was placer mined from 1907 to 1914 (Cobb, 1976 [OFR 76-662]), and more recently, as indicated by workings marked on the Fairbanks (D-3) SE topographic map. In 1996, R.B. Gravel Co. (Jerry Hassel) mined a paystreak along Ready Bullion Creek (Swainbank and others, 1997, p. 26).
Indication of production	Yes; medium
Production notes	The creek was mined from 1907 to 1914 with production well over 25,000 fine ounces (Cobb, 1976, OFR 76-662). There is no production information available for more recent mining which has continued inermittently to the present.
