Economic information

Comments on the geologic information

  • Geologic Description = Quartz-carbonate veins are exposed in a 15 m-wide zone along the south canyon wall where they cut interbedded siltstone and shale of the Hunt Fork Shale. The veins are up to 30 cm wide and can be traced for at least 8 m along strike. Barite is mainly concentrated along the vein margins which locally contain breccia and slickensides. The vein margins also contain minor chalcopyrite and galena.
