Location: This occurrence represents several sites where placer samples were collected in north-flowing tributaries along an 8-mile-long section of the Susitna River in Devils Canyon. The sites extend upstream from the west edge of sec. 31; the midpoint of these sites is in the SW1/4 sec. 2, T. 31 N., R. 1 E., Seward Meridian.
Geology: Gold and platinum occur in alluvial gravel deposits in north-flowing tributaries to the Susitna River in Devils Canyon (Kurtak and others, 1992). Stream-sediment samples collected from several sites along the Susitna River contain up to 0.002 ounce of gold per cubic yard, 120 parts per million silver, 0.2 percent copper, 0.2 percent zinc, 180 parts per million tin, and 0.86 part per million platinum. The rocks in the area consist of Tertiary granodiorite (Csejtey and others, 1978).
Workings: Sampling of alluvial gravel by U.S. Bureau of Mines (Kurtak and others, 1991).
Age: Quaternary.
Commodities (Major) - Au, Pt; (Minor) - Ag, Cu, Sn, Zn
