|Location and accuracy||Cobb (1972, MF-413), loc. 55; NW1/4 sec. 9, T. 3 N., R. 3 E., of the Fairbanks Meridian. This prospect is located near the confluence of the two headwater forks of Kokomo Creek at an elevation of about 1,500 feet. It is approximately 1 mile north of Coffee Dome. Accuracy is within 2,000 feet.|
Geologic descriptionBy 1931, several hand trenches exposed four or five quartz-bearing shear zones approximately 100 feet apart (Hill, 1933). The shear zones trend N 40 W and dip 45-60 SW The prospect is hosted in flat-lying biotite schist. One shear consists of an 8-foot-thick zone of mixed schist and quartz although most of quartz-rich portions are 1 to 2 feet wide. A 20-inch-wide quartz shear zone contained 0.36 ounces of gold per ton. In 1938, two 15-foot shafts were sunk on the prospect but no information about these shafts is known (Reed, 1939). Placer gold was produced from Kokomo Creek below the Egan prospect but its relationship to mineralization on the Eagan prospect is unknown (Burand, 1968).

Additional commentsThis prospect was discovered and staked by J.J. Egan and Dan Egan about 1930 (Hill, 1933).
