Silver King Prospect, Hyder District, Prince of Wales-Outer Ketchikan Borough, Alaska, USA

Prospect could not be located 1972-1973. Some records link the Silver King and Marietta (BC026) claims, but the Silver King prospect is at a lower elevation and farther south (Berg and others, 1977, p. 39, 77). Site is in Misty Fiords National Monument.
Location: The Silver King prospect (Buddington, 1929, p. 100; Elliott and Koch, 1981, p. 11, loc. 28) is in Section 9 at an elevation of about 3800 feet on a steep west-facing mountainside overlooking Chickamin Glacier. It is about 1.1 mile north-northwest of Texas Lake. This location is probably accurate to within about a quarter of a mile.
Geology: The country rocks in the area near the Silver King prospect are metamorphosed pelitic strata of the Jurassic or older Mesozoic Hazelton Group; the Triassic Texas Creek Granodiorite, which underlies and locally intrudes the Hazelton; and the Eocene Hyder Quartz Monzonite, which intrudes the Hazelton and Texas Creek rocks (Smith, 1977; Berg and others, 1977, p. 15-18, 22-23). Buddington (1929, p. 99-100) describes the deposit as a quartz fissure vein 6-30 inches thick in graywacke and argillite cut by a quartz diorite dike. The vein contains 2-8 inches of solid sulfides, including sphalerite, galena, pyrite, chalcopyrite, tetrahedrite, and a little arsenopyrite; a little barite also is present. A sample of the solid sulfides, chiefly galena, assayed 1.28 oz of Au and 5.96 oz of Ag per ton, 55% Pb, and 2.2% Cu. This prospect could not be located in 1972-73, probably owing to snow cover (Berg and others, 1977, p. 38-39). Lead-isotope studies of galena at the Silver King prospect indicate that the deposit is Eocene in age, contemporaneous with emplacement of the Hyder Quartz Monzonite (Maas, 1995, p. 229-248).
Workings: According to Buddington (1929, p. 99-100), the lower exposure of the vein was stripped for 50 feet, and the upper exposure was stripped for 8 feet. An early assay of a sample of the solid sulfide part of the vein showed 1.28 oz of Au and 5.96 oz of Ag per ton, 55% Pb, and 2.2% Cu.
Age: Lead-isotope studies of galena at the Silver King prospect indicate that the deposit is Eocene in age, contemporaneous with emplacement of the Hyder Quartz Monzonite (Maas, 1995, p. 229-248).
