Comments on the production information

  • MINE WAS SHUT DOWN, APPARENTLY PERMANENTLY IN 1983.CAPACITY WAS ABOUT 500,000T/YR PRODUCT. MINING WAS ON RESIDUAL ACCUMULATIONS, GENERALLY BETWEEN LIMESTONE PILLARS. SINCE THERE ARE NO CONTINOUS ORE HORIZONS ON WHICH TO BASE RESOURCE QUANTITIES, RESOURCES ARE ONLY BROADLY ESTIMATED AT 5MT.
