  • Type Owner
    Owner Sr. Arnulfo Carbajal

Comments on the production information

  • SOME OF THE VEINS WERE MINED EXTENSIVELY DURING THE EARLY 1900'S WHEN THE SMELTER AT THE NORTH END OF QUEBRADA TUCO WAS IN OPERATION. TWO MINES WERE WORKED IN 1949 BY SMALL-SCALE HAND MINING METHODS. YEARLY PRODUCTION THAT FOLLOWED AVERAGED (MAY STILL AVERAGE) 35 TONS OF LEAD-SILVER-COPPER CONCENTRATE. INACTIVE DEVELOPED PRODUCER (1949).

Comments on the reserve resource information

  • DOUBTFUL THAT RESERVES ARE LARGE ENOUGH TO MAINTAIN INCREASED PRODUCTION FOR MORE THAN A FEW YEARS UNLESS LARGER ORE BODIES ARE DISCOVERED. THE COSMOS MINE SHOWS MOST POTENTIAL
  • OUTPUT COULD BE INCREASED BY MORE EXTENSIVE MINING, BUT MOST OF THE VEINS ARE SMALL AND LOW GRADE (1955).
  • PROBABLY LESS THAN 0.1 MILLION TONS

Comments on the workings information

  • ORE MINED FROM SURFACE PITS
