Deposit DEPOSIT COULD BE MINED OUT SOMETIME IN 1990 THE IN-SITU RESOURCE QUOTE OF 328,000 MT IN 1982, WHEN DIVIDED BY THE ANNUAL PRODUCTION OF 40,000 MTPY, SHOWS A LIFE OF ABOUT 8 YEARS, WHICH MEANS THAT THIS PROJECT COULD BE EXHAUSTED BY NOW (1991), UNLESS EXTRA RESOURCES HAVE BEEN DISCOVERED, OR PRODUCTION HAS SLOWED.
