Comments on the workings information

  • MORE THAN 2000 M OF UNDERGROUND WORKINGS BY MEANS OF NUMEROUS ADITS, SPACED ABOUT 10 M APART, ALONG INDIVIDUAL MANTOS. IN PLACES MANTOS ARE WORKED BY MEANS OF TRENCHES AND OPEN CUTS. DEVELOPMENT BY EMUSA IS CONFINED TO MANTO 11, WORKED ON 0, 60, AND 150 M LEVELS USING SUB-LEVEL STOPING.

Comments on development

  • TRANS-AMERICA RESOURCES INC. EXPLORED PROPERTY FROM 1966 TO 1968, DRIVING A 730 M CROSSCUT ADIT AND 1063 M OF DRIFTS AND RAISES. SUBSEQUENTLY EXPLORED BY NEW JERSEY ZINC WHICH DRILLED SIX INCLINED DIAMOND DRILL HOLES INTERSECTING LOW-GRADE TIN MINERALIZATION AT DEPTH. THESE HOLES WERE PARALLEL TO THE PRINCIPAL SET OF MINERALIZED FRACTURES. EMPRESA MINERA UNIFICADA ACQUIRED PROPERTY AND BEGAN MINING AND MILLING ORE FROM THE OUTCROP OF MANTO 1 MIXED WITH DUMP ORE YIELDING A MILL FEED OF 0.30-0.35% SN. ; ECON.COM: EARLY PRODUCTION EXTRACTED FROM ADIT TUNNELS DRIVEN INTO RICHER PORTIONS OF MANTOS WAS HAND SORTED. TRANS-AMERICA RESOURCES INC., TREATED DEVELOPMENT ORE IN A 50 TPD PILOT MILL BETWEEN 1966 AND 1968. CIA MINERA KELLGUANI USED A 200 TPD MILL TO TREAT DEVELOPMENT ORE. THE EMUSA MILL EMPLOYS JIGS AND TABLES AND RECOVERS 52 TO 56% OF SN AS A 40 TO 42% SN CONCENTRATE FROM 0.3 TO 0.5% SN FEED. TAILS CONTAIN 0.15% SN. MILL WAS TREATING 9000 MT/MO ORE CONTAINING 0.46% SN IN 1982,
  • YIELDING 600 TO 900 KG/DAY TABLE CONCENTRATE CONTAINING 59% SN.

Subject category Comment text
Deposit AT LEAST TEN MANTOS, 1 TO 40 M THICK, WITHIN A STRATAGRAPHIC INTERVAL OF 450 TO 600 M. INDIVIDUAL MANTOS ARE DISCONTINUOUS STOCKWORK VEINS, UP TO 5 CM WIDE, 10 TO 40 CM APART, WITH NARROW TOURMALINE-CHLORITE ALTERATION SELVAGES, CONFINED TO FINE-GRAINED QUARTZITE SANDWICHED BETWEEN SHALE BEDS. FRACTURES STRIKE NW AND NE, WITH THE BEST-MINERALIZED FRACTURES SUBPARALLEL TO STRIKE OF HOST QUARTZITE, AND ARE FILLED MAINLY BY CASSITERITE AND QUARTZ. MINERALIZATION IN THE LARGEST MANTO (MANTO 7 AVERAGING 40 M THICK) IS MORE COMPLEX AND CONTAINS ARGENTIFEROUS GALENA, SPHALERITE, CHALCOPYRITE, ETC.
