Location and accuracy	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]).

Geologic setting

Geologic description 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.

Production and reserves

Workings or exploration	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]).
Indication of production	Yes; small
Production notes	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.
