|Location and accuracy||This occurrence is at an elevation of about 2,500 ft approximately 3/4 mile south of Chekhechunnjik Creek (sec. 9, T. 30 N., R. 3 E., of the Fairbanks Meridian ) and 12 1/2 miles southeast of the east end of Ackerman Lake. It is 14 miles northeast of Thazzik Mountain. This site corresponds to unnamed loc. 80 in DeYoung (1978). The location is accurate within a 1-mile radius.|
Geologic descriptionThe brief description of this prospect provided by Brosgé and Reiser (1972) indicates only anomalous gold and silver values in samples from a vein described as a single, thin, arsenic-rich vein in a system of east-west-trending quartz veins. The samples returned values as high as 3.6 ppm Au; Ag values were 1 to 3 ppm. Brosgé and Reiser (1972) also note several additional weakly anomalous rock and soil samples in an area which extends several miles to the southwest of the principal occurrence. The area is mapped as dark gray to black, gray to reddish-brown weathering, quartz-muscovite schist (Brosgé and Reiser, 1964).
