Comments on the production information

  • MAGNESIUM FROM DOLIME SUPPLIES APPROXIMATELY 50 PCT OF TOTAL MGO CONTENT OF PRODUCT. ALTHOUGH ACTUAL MILL RECOVERY FROM BRINES IS 96 PCT, MGO FROM DOLIME GIVES AN EFFECTIVE RECOVERY OF 192 PCT.

Comments on the reserve resource information

  • DOW PLANS TO CEASE BRINE RECOVERY OPERATIONS AS ON 1/87 CURRENTLY DOW RECOVERS BRINE BY MEANS OF WELLS AND TREATS BRINE TO RECOVER MG(OH)2; MARTIN MARIETTA BASIC PRODUCTS ADJACENT PROPERTY FURTHER TREATS CONC TO RECOVER MGO PRODUCTS ADIT UPDATE 1993: CLOSED 1989, BUT SOME RESERVES REMAIN. SEE MATRIX 2 FOR UPDATED RESERVES.
  • PUBLISHED INFORMATION CALLS RESERVES INDEFINITE; NUMEROUS GRADE ANALYSES AVAILABLE; AVERAGE REPORTED GRADES ARE: CACL2 - 19.6%; MGCL2 - 3.3%; NACL - 5.1%; KCL - 1.7%; BR2 - 0.22%.
  • Q-RESERVES BASED ON 25 YEAR LIFE. ACTUAL RESOURCES ARE PROBABLY MUCH GREATER. PUBLISHED SOURCES CALL THE RESOURCE INDEFINITE. . MATRIX 2 REPRESENTS RESERVES ESTIMATED FOR THE ADIT UPDATE (1993).

Comments on other economic factors

  • MOST CAPITAL COSTS HAVE BEEN DEPRECIATED. OPERATING COST FOR BRINE EXTRACTION AND TRANSPORT INCLUDED IN MILL OPERATING COST. WORKING CAPITAL EQUALS 90 DAYS OPERATING COST. MILL OPERATING COST WOULD INCREASE BY 30% AFTER 15 YEARS TO ACCOMMODATE HIGHER MAINTENANCE COSTS.
  • THIS SEQUENCE NUMBER DESCRIBES THOSE OPERATIONS REQUIRED TO RECOVER MG(OH)2 FROM BRINES. THIS IS ONLY A SMALL PART OF THE DOW CHEMICAL COMPLEX; THAT TOTAL PROC. PLANT IS FOUND UNDER SEQ. NO. 026-111-9002 (MILS ONLY). DOW CHEMICAL MI. BRINE WELL OPERATIONS CONSIST OF A BROMINE PLANT, MAGNESIA PLANT, CALCIUM CHLORIDE PLANT, AND IODINE PLANT. BECAUSE EACH PLANT IS CAPABLE OF OPERATING INDEPENDENTLY (WITH MINOR MODIFICATIONS), ONLY THE MAGNESIA PLANT IS DESCRIBED HERE. DOW RECOVERS THE COMMODITIES IODINE, BROMINE, MAGNESIUM HYDROXIDE, MAGNESIUM SULFATE, AND CALCIUM CHLORIDE. ONLY MAGNESIUM HYDROXIDE RECOVERY IS DESCRIBED. THE MAGNESIUM SULFATE IS RECOVERED FROM THE MG(OH)2 AT A LATER STAGE, SO IT IS NOT DISCUSSED HERE. PRODUCTION IS ESTIMATED BASED ON THE RATED CAPACITY OF THE MAGNESIA PLANT ONLY, NOT FOR THE TOTAL OPERATION. THUS, THE ACTUAL PRODUCTION RATE MAY VARY FROM THE RATE REPORTED HERE. THE OPERATION IS CURRENTLY RUNNING AT APPROX. 50% OF MGO CAPACITY.
  • THIS OPERATION IS NOT A TYPICAL UNDERGROUND OPERATION. 17 WELLS ARE ASSUMED TO BE PUMPING. TOTAL WELL FIELD HAS OVER 104 WELL SITES.
