Location: The Redskin prospect is at an elevation of about 1,400 feet on the ridge south of Beaver Creek. The map site is in the E1/2 of section 6, T 8 N, R 55 W, of the Seward Meridian. The prospect is at the head of locally named Alder Gulch, 1.15 miles west-southwest of the Beaver Creek airstrip. It is locality 4 of Cobb (1972 [MF 384]; 1976 [OF 76-606]).
Geology: At the Redskin prospect, cinnabar occurs as sparse films along bedding planes and cross joints, and in zones of brecciation in graywacke and shale (Rutledge, 1950). This prospect has not received much study, but is reported to be similar to the mercury-bearing deposit along locally named Canary Gulch at the Lucky Day mine (TA004), 0.75 mile to the northwest (Rutledge, 1950; Cady and others, 1955, p. 115). The country rocks are inferred to be part of a Paleozoic and Mesozoic sedimentary and volcanic sequence; several Triassic fossil localities are in the Cinnabar Creek area about 4 miles to the northwest of the Redskin prospect (Sainsbury and MacKevett, 1965). Rutledge (1950) also reports that cinnabar float has been found in locally named Alder Gulch below the Redskin prospect.
Workings: The prospect probably has been explored by surface examination, sampling, and some shallow pits.
Age: Cretaceous or Tertiary. Inferred to be similar in age to other mercury deposits of southwest Alaska that postdate deposition of mid-Cretaceous clastic sedimentary rocks and intrusion of Upper Cretaceous or Tertiary igneous rocks.
