Comments on the geologic information

  • Geologic Description = Cinnabar, stibnite, realgar, and possibly orpiment are in quartz gangue deposited irregularly along faulted joints, fractures, and bedding planes in Cretaceous graywacke and shale, near silica-carbonate altered dikes. There are several discrete ore zones.

Economic information about the deposit and operations

Development status Past Producer
Commodity type Metallic

Comments on exploration

  • Status = Inactive

Mining district

District name Aniak

Comments on the production information

  • Production Notes = Total = 14 or 16 flasks of mercury (Miller and others, 1989)

Comments on the workings information

  • Workings / Exploration = 122 ft adit, 80 ft of crosscuts, pits, and trenches. USBM samples yielded an average grade of .41 lb/ton mercury and maximum 16.5 lb/ton. (Webber and others, 1947)
