Location: This placer prospect is at an elevation of approximately 100 feet on Herbert River near the terminus of the Herbert Glacier. It is in the SE1/4SE1/4 section 32, T. 38 S., R. 65 E. of the Copper River Meridian. The location is accurate.
Geology: The Herbert Glacier gold placer prospect consists of glacial sand deposited near the terminus of the glacier. The sand was mined in 1932 and 1933 and processed with a centrifugal concentrator, but recovery was poor and the operation failed. Native gold-bearing quartz veins outcrop upstream from this prospect along the southern margin of Herbert Glacier (JU097) (Redman and others, 1989).
Workings: Glacial sand from the Herbert River was mined in 1932 and 1933 and processed with a centrifugal concentrator, but recovery was poor and the operation failed.
