Comments on the geologic information

  • Geologic Description = According to Reed and Elliott (1968, C 596), the Hippie Creek-South occurrence consists of locally abundant calcite, pyrite, and galena and minor to trace sphalerite and stibnite (?) in several 2 to 8 cm thick shear zones in limestone of the Terra Cotta Mountains Sandstone, a formation of the lower Paleozoic Dillinger subterrane (Bundtzen and others, 1988, 1997). The mineralized shear zone is parallel to a 6 m thick, pyrite-bearing felsite porphyry dike swarm (Bundtzen and others, 1988). The dikes are undated but a similar plutonic suite to the south yielded a 60.5 Ma age (Solie and others, 1991). The shear zone is discontinuously mineralized.? Analyses cited in Reed and Elliott (1968, C 596) contained greater than 1,000 ppm silver, 1,000 ppm arsenic, greater than 0.50 percent lead, 0.30 percent antimony, and greater than 1.00 percent zinc.
  • Age = Unknown; inferred to be mid-Tertiary, based on isotopic age dating of nearby genetically related plutonic rocks (Solie and others, 1991).

Comments on the workings information

  • Workings / Exploration = The Hippie Creek-South occurrence was found and investigated by the late Bruce Reed during regional geological investigations in the southern Alaska Range by the U.S. Geological Survey (Reed and Elliott, 1968, C 596). Selected analyses contain greater than 1,000 ppm arsenic, greater than 0.50 percent lead, 0.30 percent antimony, and greater than 1.0 percent zinc.
