| Deposit | SHAFTS ON TOP OF HILL ALONG PARALLEL NW-STRIKING VEINS ASSOCIATED WITH FISSURE-FILLING VEIN SYSTEMS POSSIBLY ALONG- JOINT SETS. COPPER MINERALS AND URANIUM OCCUR ALONG STRIKE OF- VEINS. ZONE OF STRONGEST CU-U MINERALIZATION WAS REPORTED TO -BE 300-400 FT WEST OF MAIN OPEN PIT, WHERE A REMNANT OF AULD L-ANG SYNE SEDIMENTS IS PRESERVED AS A ROOF PENDANT. THE ZONES O-F STRONGEST MINERALIZATION ARE THOSE WHICH ARE THE MOST CALCAR-EOUS. THREE SAMPLES FROM THE NURE PROGRAM ASSAYED BETWEEN 144 -AND 334 PPM U; THESE SAMPLES CAME FROM CALCAREOUS SEDIMENTS. S-AMPLE 2864 IS FROM THE CONTACT-TYPE DEPOSIT OF TACTITE . URANIUM IS SPOTTY WITH HIGH-GRADE INDIVIDUAL PIECES, BUT MINING WOULD LOWER ORE GRADE BELOW ECONOMIC LEVELS |
