Comments on the geologic information

  • Geologic Description = The Starship prospect consists of a smithsonite-bearing solution breccia in dolomite and limestone of the Paradise Fork Formation of Dutro and Patton (1982); this is unit 'Sic' of Andrews and Rishel (1982). Zone of mineralization measures about 15 feet by 100 feet (4.5 m by 30 m) and is mainly in rubble crop. Age of host unit is Silurian (inferred), based on fossil control. (Patton and others, 1980; Dutro and Patton, 1982; Schmidt, 1997). The age of the mineralization is unknown. Grab samples from surface explorations of high grade mineralization contain up to 23.25 percent zinc and 0.14 percent cadmium. Mineralized rubble crop distribution indicates a relatively small and discordant mineral body.
  • Age = Age of host unit is Silurian (inferred), based on fossil control. (Dutro and Patton, 1982). The age of mineralization is unknown.

Comments on the workings information

  • Workings / Exploration = The Starship prospect was found by WGM Inc. and Patino Ltd. in the late 1970s during base metal exploration on lands selected by Doyon Ltd (Andrews and Rishel, 1982). Grab samples from surface explorations of high grade mineralization contain up to 23.25 percent zinc and 0.14 percent cadmium. Mineralized rubble crop distribution indicates a relatively small and discordant mineral body.
