Discussion

Ore body information: BLANKET

THE REPLACEMENT DEPOSIT IS IN LIMESTONE BELOW A THIN SANDSTONE CAPPING A FEW INCHES TO THREE FEET THICK. A FEW SHALE BEDS ARE ASSOCIATED WITH THE SANDSTONE MAKING IT RELATIVELY IMPERVIOUS AND RESISTANT TO REPLACING SOLUTIONS. COARSE FLUORITE ORE AND FINER BANDED ORE OCCUR IN THE MINE.

THE DEPOSIT IS EXPLOITED BY IRREGULAR DRIFTAND FLAT-LYING STOPES

BEDDED FLUORITE DEPOSITS PRIMARILY FORM BY SELECTIVE REPLACEMENT OF LIMESTONE BEDS. WATER FOR THE ACCOMPANYING MILL WAS PUMPED FROM A SINK-HOLE LAKE ONE MILE TO THE SOUTH.
