Location: The Saint Patrick mine is located in the SE1/4 NW1/4 sec. 33, T. 1 N., R. 2 W., Fairbanks Meridian. The exact location of placer mining activity along Saint Patrick Creek is unknown. The placer is about 2.8 miles east-southeast of the top of Ester Dome. The mine is locality 49 of CObb (1972 [MF 410]).
Geology: Placer mining and prospecting took place along St. Patrick Creek between 1909 and 1916 (Cobb, 1976 [OFR 76-662, p. 128]). Prindle and Katz (1913) reported that in 1910 $17,000 of gold was produced with the gold valued at $17.50 per ounce. This does not agree with Ellsworth and Parker (1911, p. 158), who reported that very little actual mining took place in 1910.
Workings: Placer mining and prospecting took place along St. Patrick Creek between 1909 and 1916 (Cobb, 1976 [OFR 76-662, p. 128]). In 1925, churn drills were in operation to prospect suitable ground for dredging but no dredging resulted (Wimmler, 1925 [ATDM MR 195-8, p. 54]).
Age: Quaternary placer.
Production: Prindle and Katz (1913) reported that in 1910 $17,000 of gold was produced (gold valued at $17.50 per ounce) This does not agree with Ellsworth and Parker (1911, p. 158), who reported that very little mining took place in 1910.
