Deposit 1974-HANNA-CHEVRON IS UNDERSTOOD TO HAVE SIGNED A MEMORANDUM ENT WITH THE INSTITUTE FOR INDUSTRIAL DEVELOPMENT, TO DEVELO ICKEL DEPOSITS. COSTS OF DEVELOPMENT ARE ESTIMATED AT $200 , WITH PRODUCTION START UP SCHEDULED FOR FOUR YEARS FOLLOWIN ACT APPROVAL AT 37.5 MILLION LB/YR. AL AT 37 MILLION LB/YR. DEPOSIT IS OVAL SHAPED. THE TWO "S" RECORDS ARE REPRESENTATIVE OF ONE SURFACE MINE WITH A SIGNIFICANT CHANGE IN CAPACITY .THEREFORE, THERE ARE TWO "K" RECORDS THAT REPRESENT ONE CONCENTRATOR FOR THE SURFACE MINE ALSO,THERE IS ONE PRODUCT,BUT IT HAD TO BE SPLIT BETWEEN THE DIFFERENT CAPACITIES. THE NEW DEVELOPMENT SCHEDULE RECORD 2 IS LISTED AS PROBABLE FOR 1993-94. THE DUALITY OF SURFACE, CONCENTRATOR, AND PRODUCT TABLES HAS BEEN MAINTAINED TO REFLECT THE PLANNED UPGRADE.
