|Location and accuracy||Occurrences of placer gold are present in a several square mile area centered on USGS benchmark Only in the Lime Hills A-4 quadrangle (Eppinger, 1993). The map site is at an elevation of 1,700 feet on one of the drainages flowing north from these uplands in the south-central part of section 25, T 12 N, R 30 W, of the Seward Meridian. The map site is chosen to represent the general area of gold occurrences.|
Geologic descriptionPan concentrates from several drainages in this area contain detrital gold (Eppinger, 1993). The gold includes grains with sharp edges, embayments, and other delicate features. Bedrock in the area is dominantly Cretaceous clastic sedimentary rocks (Eppinger, 1993).
