Current site name Unnamed (in Daisy Swift Creek)

Geographic coordinates

Geographic coordinates: -165.66139, 64.71678 (WGS84)
Relative position Daisy Swift Creek is a mile-long east tributary to upper Cripple River. Its mouth is 4.5 miles upstream from where the Nome-Teller road crosses Cripple River. The location is of the stream sediment anomaly at an elevation of about 650 feet; it is within about 500 feet of outcropping mineralized rock.

Comments on the geologic information

  • Geologic Description = During reconnaissance mapping of the area in 1990 by Kennecott Exploration Company, 2,300 ppm zinc and anomalous amounts of gold were found in a stream sediment sample from Daisy Swift Creek. The gold content of a panned concentrate from Daisy Swift Creek, collected about 2,000 feet above its mouth, was 1,570 ppb gold. Followup of stream sediment and panned concentrate samples led to discovery of a pyritized metabasite unit that contained more than 0.1 ounce of gold per ton and anomalous amounts of antimony. The source of the zinc anomaly was not determined. Daisy Swift Creek flows generally northwest in a schist unit between major bodies of the massive marble unit of Bundtzen and others (1994). The schist is mainly calc-schist, but locally it includes silicic units of probable felsic volcanic origin. The schist also includes large boudin-like masses of metabasite (C.C. Hawley, Cindy Buxton, and D.L. Olson, written communication, 1992).
