Comments on the production information

  • COMBINED PRODUCTION OF MOROCOCALA, JAPO, AND SANTA FE MINES OF COMIBOL

Comments on the reserve resource information

  • DUE TO NARROW WIDTH OF MOST VEINS, IT IS IMPOSSIBLE TO PROJECT RESERVES FAR IN ADVANCE. ABOVE RESERVES SECURE THE MINE FOR 6-7 YEARS.
  • FUTURE PROSPECTING OF SANTA FE - MOROCOCALA, AND SOUTHWARD BENEATH VOLCANIC TUFF COVER OFFER FAIR POTENTIALS FOR NEW RESERVES. DEPOSITS HAVE LIMITED VERTICAL RANGE

Comments on the workings information

  • AVERAGE WIDTH OF VEINS AT JAPO MINES 1.6M WITH 1.6% SN; AT SANTA FE MINES, 0.92M WITH 0.62% SN; AT MOROCOCALA MINES, 0.70M WITH 1.29% SN.
