Discussion

THE ROOF ROCK IS ROSICLARE SANDSTONE AND IT BASAL SHALE AND THE ROCK BENEATH THE ORE IS FREDONIA LIMESTONE.

Ore body information: BLANKET

THERE ARE TWO ZONES OF BANDED ORE. REPLACEMENT IS NEARLY COMPLETE IN THE UPPER ZONE, AS THE FINE-GRAINED BANDS CONSIST LARGELY OF FLUORITE WITH A LITTLE QUARTZ AND VERY LITTLE CALCITE, WHEREAS IN THE LOWER ZONE THE FINE-GRAINED BANDS CONTAIN ABUNDANT CALCITE.
