Discussion

SMALL AMOUNTS OF CERUSSITE AND SMITHSONITE ARE PRODUCTS OF WEATHERING.

ORE REPLACES CERTAIN BEDS OF FREDONIA LIMESTONE NOT FAR BELOW ROSICLARE SANDSTONE.

SEVERAL SMALL OPEN PITS AND SMALL DRIFTS DEVELOP THE BLANKET DEPOSIT. ONE PIT WAS 20 FT BY 15 FT AND 30 FT DEEP AND EXPLOITED A 6-INCH WIDE FLUORITE VEIN STRIKING N 45 E AND DIPPING 80 NW.

THE WATER SUPPLY WAS FROM A SPRING WHICH WAS IN TURN FED BY A SINK-HOLE LAKE.
