The prospect is in the Tracy Arm-Fords Terror Wilderness Area which is closed to prospecting and mining.
Location: The Gold Nest prospect is at an elevation of about 2,900 feet southeast of the saddle that is about 1.4 miles southeast of the southwest end of Lower Sweetheart Lake. The prospect is near the center of section 28, T. 45 S., R. 73 E.
Geology: Claims were staked on the Gold Nest prospect in 1912 (Kimble and others, 1984). The deposit consist of a brecciated pyrite-quartz vein 30 inches thick that is exposed in a short open cut. The vein strikes N30E and dips steeply northwest. A chip sample across the vein contained 1.5 part per million (ppm) silver, 0.10 ppm gold, 70 ppm copper, 70 ppm lead, and 130 ppm zinc. Boulders of a quartz vein with arsenopyrite were found about 200 feet above the breccia vein. A select sample of the boulder contained 0.5 ppm silver, 7.0 ppm gold, 40 ppm copper, 950 ppm lead, and 75 ppm zinc. The rocks in the area are part of the Cretaceous biotite-schist unit of Brew and Grybeck (1984).
Workings: The only working is a short open cut on a claim.
Age: Cretaceous or younger based on the age of the host rock.
Commodities (Major) - Ag, As, Au, Cu, Pb, Zn
Development Status: None
Deposit Model: Pyrite-quartz vein.
