Deposit JASPERIZED U-BAR LIMESTONE IS ALMOST CONTINUOUS FOR SEVERAL HUNDRED FEET SW OF THE WILSON PROSPECT ALONG THE U-BAR FAULT, AND IN PLACES, THE JASPERIZATION EXTENDS LATERALLY INTO THE WALLROCK FOR MORE THAN 200 FT. A SMALL AMOUNT OF EXCAVATING IN ONE AREA ALONG THE FAULT HAS EXPOSED APPRECIABLE FLUORITE OVER AN AREA 100 FT BY 150 FT. THE FLUORITE IS COARSELY CRYSTALLINE, CLEAR TO EMERALD GREEN, AND IS ASSOCIATED WITH COARSE CALCITE.
Deposit THE U-BAR FAULT PROSPECTS CONSIST OF SEVERAL OCCURRENCES OF FLUORITIZED JASPEROID FOR SEVERAL HUNDRED FEET SW OF THE WILSON PROSPECT ALONG THE U-BAR FAULT. THE WILSON PROSPECT, THEREFORE IS ONE OF THE U-BAR FAULT PROSPECTS. ; INFO.SRC : 1 PUB LIT
