Location: The Last Chance mine is located in the NW1/4NE1/4 sec. 32, T. 1 N., R. 2 W., Fairbanks Meridian. This deposit is near the head of Saint Patrick Creek at an elevation of about 1,000 feet. It is about 1.8 miles east-southeast of the top of Ester Dome. This mine is included in locality 17 of Cobb (1972 [MF 410]).
Geology: Gold has been produced from a steeply dipping quartz vein that is two feet thick and contains arsenopyrite, stibnite, and visible gold. The vein strikes northeast and dips steeply northward (Davis, 1922, p. 59; Chapman and Foster, 1969, p. D18). One hundred and twenty-five tons of ore were mined from short drifts off a 60-foot shaft; the ore reportedly ran $30 in gold per ton (about 0.048 ounce of gold per ton) (Davis, 1922, p. 59-60).
Workings: One hundred twenty-five tons of ore were mined from short drifts off a 60-foot shaft (Davis, 1922, p. 59-60).
