Comments on the geologic information

  • THE COMSTOCK ORE BODY IS MOSTLY TABULAR IN SHAPE BUT CERTAIN PORTIONS OF IT ARE IRREGULAR. FISSURE TYPE DEPOSITS HAVE NOT BEEN FOUND IN THE COMSTOCK MINE YET, BUT IT IS SUSPECTED THAT THEY ARE PRESENT IN VERY MINOR AMOUNTS. THE DIP AND STRIKE OF THE OREBODY AT THE COMSTOCK MINE ARE ESTIMATES FROM THE LITERATURE AND FROM WHAT WAS OBSERVED IN A VISIT TO THE MINE.
  • THE ORE IS KNOWN TO CONTAIN VERY MINOR AMOUNTS OF HEMATITE, WHICH IS MIXED WITH MAGNETITE. HOWEVER, THE PERCENT OF HEMATITE IS UNKNOWN.
