Geographic coordinates

Geographic coordinates: -136.79212, 58.85972 (WGS84)
Relative position The Sunrise is on the east side of Reid Inlet about 1 mile south of the mouth of the inlet at an elevation of about 800 feet. The deposit is uncertainly located. Claims were staked by Joe Ibach and Rex Beach in 1937 between the beach to at least 800 feet elevation. Rossman (1959, B 1058-B) reports a vein at about 700 feet elevation possibly traceable for several thousand feet in badly shattered sedimentary rock. The prospect is location number 26 of Cobb (1972).

Comments on the geologic information

  • Geologic Description = Country rocks are mainly hornfels and marble of Paleozoic age (Brew and others, 1978). The rocks are cut by mafic (lamprophyric) dikes and small granitic intrusions and are badly broken. Subparallel quartz-calcite veins occur in north-striking, steeply-dipping marble and hornfels. ? Veins investigated by the U.S. Geological Survey in 1966 (MacKevett and others, 1971, p. 62-63, loc. H, table 11) were discontinuous, 2-12 inches thick and 20-40 feet long. Quartz veins in the lamprophyre dikes contain pyrite, which is also disseminated in the dike rock. Reed (1938) reported a vein that contained 0.08 ounce per ton gold. Rossman (1959, p. 56) reported scheelite in a quartz vein. Negligible amounts of metals were found by Kimball and others (1978) in their study of the area.
  • Age = Cretaceous or younger.
