Significant No

Mining district

District name Southeast Missouri

Comments on the workings information

  • A SHAFT WAS SUNK 50 FT DEEP IN 1892 AND WAS EXPECTED TO REACH DEPTHS OF 100 FT OR MORE, OR UNTIL ORE WAS REACHED.

Comments on development

  • ON THE WEST SIDE OF THE ORE BODY A SHAFT IS BEING SUNK. IT HAS PENETRATED ALMOST 50 FT. IN LOOSE SACCHARDIDAL SANDSTONE, WITH NO ORE IN SIGHT. IT IS INTENDED TO SINK AT LEAST 100 FT. OR UNTIL LIMESTONE IS STRUCK. DRIFTS WILL THEN BE RUN IN VARIOUS DIRECTIONS ( CRANE, G. W., 1912 ).
