Comments on the reserve resource information

  • AS IS SHOWN IN THE M-DATA SET, THE ACTUAL FLUORITE GRADE IS MUCH HIGHER THAN THE LISTED 75%, BUT BECAUSE OF THE SILICA CONTENT THE EFFECTIVE GRADE IS ACTUALLY THE ASSAY GRADE MINUS 2.5 TIMES THE SILICA GRADE (2.5X4=10;85-10=75).

Comments on the workings information

  • ALL WATER IS TRUCKED IN AND USED FOR CULINARY PURPOSES ONLY. NO SHOWER FACILITIES AVAILABLE. ALL POWER IS PRODUCED ON SITE BY A SMALL PORTABLE GENERATOR BELONGING TO THE MINE MANAGER. COOKING AND HEATING PROVIDED BY LP GAS TRUCKED TO SITE.

Comments on other economic factors

  • THE UNDERGROUND IS STILL IN THE DEVELOPMENTAL STAGE, CONSISTING OF A SINGLE 275-METER-LONG DECLINE. ALTHOUGH NO SIGNIFICANT ORE INTERCEPTS HAVE BEEN ENCOUNTERED, LIMITED PRODUCTION HAS OCCURRED, AVERAGING 4.5 TO 9.0 TONNES/WEEK. BECAUSE OF THIS LACK OF DEFINITION, NO UNDERGROUND DATA SET HAS BEEN ENTERED.
