|Location and accuracy||The Last Chance Creek mine is located in sec. 19, T. 2 N., R. 3 E., Fairbanks Meridian. This placer mine is marked in the headwaters of Last Chance Creek on the Fairbanks D-1 topographic map. The mine is about 4.3 miles east-northeast of the top of Gilmore Dome. The mine is locality 61 of Cobb (1972 [MF 410]).|
Geologic descriptionBedrock in the Last Chance Creek drainage is Fairbanks Schist that consists of quartz-muscovite schist, quartzite, and chlorite-quartz schist (Newberry and others, 1996). Placer mining took place from 1911 to 1914 and in 1925 and 1926 (Cobb, 1976 [OFR 76-662, p. 73]; Wimmler, 1925 [ATDM MR 195-8, p. 52]; Wimmler, 1926 [ATDM MR 195-11, p. 57]).
