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 setting

Geologic description

Discovery 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.

Additional comments

See also the nearby unnamed prospect on Sukapak Mountain (CH076) which is the probable source of any gold in this creek. This prospect is in the Alaska pipeline corridor which is not open to mineral entry.
