Comments on the geologic information

  • Geologic Description = Phosphate rock and phosphorites occur within a 11 m-thick section of interbedded oolitic to pisolitic limestone and calcareous shale in the Alapah Limestone. Flattened pellets up to 3 cm in size were observed in the phosphorites.
  • Age = Mississippian

Economic information about the deposit and operations

Development status Occurrence
Commodity type Non-metallic

Comments on exploration

  • Status = Inactive

Mining district

District name Colville

Comments on the workings information

  • Workings / Exploration = A chip sample across a 0.3 m-thick phosphorite contained 22.5% P2O5. Samples collected across a 2.3 m-thick section averaged 16.4% P2O5, and the entire 11 m-thick phosphatic section averaged 5.7% P2O5. Samples also contained up to 733 ppm V.
