|Location and accuracy||Cobb (1972, MF-413), loc. 30; NW1/4 sec. 1, T. 2 N., R. 1 E., of the Fairbanks Meridian. This deposit is just north of the junction of Skoogy Creek and Twin Creek, about a mile east of Pedro Dome. Accuracy is within 1,000 feet.|
Geologic descriptionOre was milled from two shafts, 40 to 50 feet deep, that connected to 400 feet of drifts and crosscuts (Brooks, 1911, p. 35). This may be the same site as the Rainbow mine (ARDF no. LG084) where gold is found in a nearly vertical quartz vein that strikes east-west. The vein contains pyrite, arsenopyrite, galena, sphalerite (Smith, 1913; B 525). The vein has been described as varying from 18 inches wide to 3 feet wide (Brooks, 1912; Chapin, 1914); it cuts schist, quartzite and granite (Chapin, 1914).
