Location: Cobb (1972, MF-413), loc. 51; NW1/4NE1/4 sec. 22, T. 3 N., R. 2 E., of the Fairbanks Meridian. This deposit is on the divide at the head of Too Much Gold Creek. Accuracy is within 1,500 feet.
Geology: High grade gold mineralization occurs in a shear zone 30 feet wide that strikes N 60 W. The shear exhibits two mineralized zones that contain quartz with pyrite, gold and stibnite, as well as irregular or kidney-shaped pods of stibnite (Brooks, 1916; B 649). Intrusive breccia was noted to be present on the dump of the Rob Roby shaft (Pilkington, 1970). A small amount of ore was custom milled from a 100-foot shaft with 170 feet of drifts (Brooks, 1916; B 649). Operation were suspended in mid-1918 because of excess water in the workings (Martin, 1920).
Workings: Workings consisted of a 100 foot shaft and 170 feet of drifts on two levels (Brooks, 1916; B 649).
Production: A small amount of ore was customed milled but production figures are not known (Brooks, 1916; B 649).
