Comments on other economic factors

  • DILUTION=150% DUE TO 2 TO 20 CM THICK HIGH GRADE ORE ZONE; HIGH DILUTION DUE TO EQUIPMENT CLEARANCE. U-CAP IS CAPACITY OF UNITS TREATED, INCLUDING WASTE MATERIAL MINED. UPC IS COST OF MT/UNIT TREATED, NOT MT OF ORE MINED.
  • IN 1976 THE ITALIAN GOVT PERMANENTLY CLOSED ALL THE NATIONS MERCURY MINES. ITALY WILL PRODUCE ITS DOMESTIC REQUIREMENTS FROM BYPRODUCT MERCURY FROM LEAD-ZINC MINES IN SARDINIA. DUE TO POOR ECONOMICS, IT IS EXTREMELY UNLIKELY THAT THE GOVT WILL EVER REOPEN EITHER ITS SELVENA OR ABBADIA S. SALVATORE MINES
  • ORE IS TRANSPORTED TO MILL AT ABBADIA S. SALVATORE, BY TRUCK FOR 22 KM. TRANSPORTATION COST IS INCLUDED IN MILL OPERATING COST MERCURY ORE AVERAGES 9-10% MOISTURE; TOO HIGH FOR DIRECT FURNACING. MUST BE SENT TO A DRYER
