Discussion

A SHORT DRIFT WAS DRIVEN IN 1903-04, BUT NO COMMERCIAL ORE WAS FOUND.

SOME SPHALERITE AND BARITE OCCUR IN THIN DOLOMITE BEDS NEAR THE MIDDLE OF THE MAQUOKETA SHALE. THE MINERALS ARE IN INDIVIDUAL MASSES ONE-HALF TO THRE-QUARTERS OF AN INCH IN DIAMETER, IN SMALL DRUSY CAVITIES IN BOTH WEATHERED AND UNWEATHERED ROCK.
