|Location and accuracy||Discovery Creek, which is not named on the 1:63,360-scale topographic map, drains the south flank of Sukakpak Mountain. It is about 1 1/2 miles long and much of it is below a gold-stibnite-quartz vein (CH076). The site is somewhat arbitrarily plotted about 1.2 miles upstream from the mouth of the creek below the vein. The site is about 0.5 mile west-southwest of the center of section 22, T. 32 N., R. 10 W.|
Geologic descriptionDiscovery Creek is downslope from the gold-stibnite-quartz veins on Sukakpak Mountain (CH076). Little is known about this prospect but clasts of stibnite-quartz-vein material have been found in the creek gravels and there is some evidence of past placer mining or prospecting (Dillon, 1982; Kurtak and others, 2002). Suction dredging was reported in 1982.
