Economic information

Comments on the geologic information

  • Geologic Description = Gossan with galena remnants in Ordovician limestone; unoxidized character and controls on mineralization are not known.
  • Age = Assumed to be related to the development of tin systems in the Lost River area and therefore Late Cretaceous, the age of the tin-mineralizing granites there (Hudson and Arth, 1983).

Economic information about the deposit and operations

Development status Prospect
Commodity type Metallic

Comments on exploration

  • Status = Inactive

Mining district

District name Port Clarence

Comments on the workings information

  • Workings / Exploration = A 35-foot shaft and two exploratory adits were completed early in the century (Knopf, 1908, p. 58-59). One 143-foot long adit intersected 7 feet of low grade galena mineralization 50 feet below the bottom of the shaft. The second adit was 600 feet long and appears to have been driven along a fault zone in limestone without success.
