| Result | FLUORITE IS IN LEAN TO 90% PURE AREAS. FLUID INCLUSION STUDIES OF THE FLUORITE SHOW LARGE FLUID INCLUSIONS AVERAGING 40 MICRONS, VARYING FROM 20 TO 120 MICRONS. THEY ARE COMMONLY NECKED AND ARE VERY ABUNDANT. THEY HAVE AN AVERAGE OF 8% WATER VAPOR AND NEARLY ALL SHOW A SLIGHT SECOND ANNULUS OF A THIRD PHASE. |
