Deposit FIRE CLAYS AND CLAY PRODUCTS ARE BEING PRODUCED FROM SE PITS IN THE AREA, FOR THE NORTHWESTERN U.S. PULP INDUSTRY. MATRIX GRADES AND TONNAGES ARE BASED ON WET TONNES. TH ALUMINUM GRADE SPECIFIED REPRESENTS TOTAL ALUMINUM CONTENT R THAN AVAILABLE ALUMINUM CONTENT. THE DRY ANALYSIS IS; 30% A 2.4% FE2O3, AND 51% SIO2. INITIAL DATA WAS ENTERED BY HUSTEAD OF GEORGIA TECH., A REVISED BY MCMAHAN IN 1975. THERE ARE THREE SETS OF COSTS; ORIGINAL 1975 COSTS; COSTS UPDATED FROM 1975 TO 1979; AND COMPLETELY RECOSTED 1979 COSTS.
