A LITTLE GALENA OCCURS IN IRREGULAR VEINLETS IN THE CALCITE. NO SPHALERITE WAS REPORTED.

Model code	174
USGS model code	26b
Deposit model name	Fluorspar deposits (fluorite veins)

THE VEIN TRENDS N 15 E AND DIPS 80 W. IT AVERAGES 4 FT IN WIDTH.

Workings at the site
Type of workings	Surface/Underground
Name of workings	SHAFT ON WEST VEIN
Overall depth	30.48M

NUMEROUS ABANDONED SHAFTS AND OPEN CUTS ARE REPORTED IN THE VICINITY. THE SHAFT ON THE WEST VEIN HAS DRIFTS ON THE 30-FT AND 100-FT LEVELS. THE 100-FT LEVEL DRIFT GOES TO THE EAST VEIN, BUT LITTLE MINING HAS BEEN DONE ON THE EAST VEIN
