Discussion

SOME OF THE CALCITE AND FLUORITE HAVE CLEARLY BEEN DEPOSITED BY REPLACEMENT. GALENA AND SPHALERITE WERE MINOR MINERALS.

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

Controls for ore emplacement: Faulting, Replacement

On Sycamore Vein

GRAY QUARTZ IS AN OCCASIONAL ACCOMPANIEMENT TO FLUORSPAR IN VUGS. SYCAMORE VEIN TRENDS N 65 E AND DIPS TO THE SOUTHEAST. IT AVERAGES 2.5 TO 3 FT THICK

INTERMITTENT COMMERCIAL PRODUCTION. MUCH SHALLOW MINING WAS DONE, SOME WITH DRAGLINE NORTH OF SYCAMORE VEIN.

Overall depth 60.96M

SEVERAL SHAFTS AND OPEN PITS ARE ALIGNED IN A DIRECTION N 42 E WHICH MAY REPRESENT THE APPROXIMATE TREND OF THE VEIN.

RESIDUAL 'GRAVEL SPAR' AND REPLACEMENT MINERALIZATION OCCUR IN THE VEIN DEPOSIT.

Year of First Production: 1900
