Comments on the workings information

  • DIMENSIONS ARE FOR THE DISTRICT WHICH CONTAINS 26 SEPARATE OREBODIES (7 TO 11 ACTIVE PITS IN 1972) FROM 250 THOUSAND TO 14 MILLION TONS EACH. THICKNESS OF ORE - UP TO 30 M.; COVER-UP TO 70 M. DEEP

Comments on development

  • ECON.COM: OPEN PIT EXTRACTION IS INEXPENSIVE BUT CLIMATE, REMOTE LOCATION AND LABOR TURNOVER (250% TO 1969) CREATE PROBLEMS.

Deposit 60 MILLION MET TONS
Deposit TRUCK HAULS TO CONCENTRATOR UP TO 12 KM AWAY AT SPEEDS UP TO 64 KM/H CAUSES SHORT TIRE LIFE. HAULAGE COSTS UP TO 1970 WERE 50% OF TOTAL PRODUCTION COST. PUMPING COSTS ARE SIGNIFICANT ALSO - $0.44 PER MT IN 1968 (INCLUDING $0.22 FOR CAPITAL)
