Comments on the reserve resource information

  • SECTION IN CONTINUOUS PRODUCTION SINCE 1926. MILL AT SUTTON/RODCAMP TREATS FINES FROM SUTTON/RODCAMP, VANAD, AND CAESAR. MILL HAS GRAVITY CONC.CAP.OF ABOUT 100,000 MTPY FINES TO PRODUCE 75,000 MTPY CONCS. ALL PRODS.TO GWERU. FOR ANALYSIS (SUTTON/RODCAMP ONLY): 36,000 MTPY ROM FOR: 11,500 MTPY LUMP AT 44 % CR2O3 AND 18,300 MTPY CONCS.AT 48.6 % CR2O3. GREAT DYKE RESOURCE. SEAMS 4,5,6,7 ON SECTION. SEAMS 4&7 = .15 M THICK, SEAMS 5&6 = .12 M THICK.
  • M9C4=M1C2. INDIVIDUAL SEAMS OCCURING ON THE SECTION (SEAM NOS. 4, 5, 6, 7, 8, 9 AND 10) PROJECTED FOR A DOWN-DIP EXTENSION OF 300 METERS (VERTICAL DEPTH OF AROUND 125 METERS). THICKNESSES OF THE 7 SEAMS OVER THE SECTION ARE ESTIMATED TO BE .10, .12, .12, .15, .15, .10, AND .12 METERS RESPECTIVELY. ESTIMATED STRIKE LENGTHS FOR ALL 7 SEAMS ARE 15,000 METERS. 50% PROB. LEVEL IS ESTIMATE FOR DOWN-DIP EXTENSIONS OF 800 M FOR SEAM 4, 1000M FOR SEAM 5, 1200 M FOR SEAM 6 AND 1500 M FOR SEAMS 7-10.
  • 1/89 INSITU DEMO.TONNAGE= SEAMS 6 & 7 ONLY TO 300 M ON-DIP. 85 % RECOVERY.

Deposit THIS ANALYSIS TREATS A SINGLE SMALL SECTION OF THE GREAT DYKE AS ONE MINEABLE UNIT-"THE SUTTON/RODCAMP SECTION? . IN REALITY, MORE THAN ONE COMPANY MAY HOLD LEASES OVER THE AREA DESCRIBED AND SIMULTANEOUS PRODUCTION IS POSSIBLE. FOR AVAILABILITY IT WAS NECESSARY TO ADDRESS THE SITUATION IN A LOGICAL, COMPARTMENTALIZED FASHION. HENCE, THE "SUTTON /RODCAMP" SECTION REFERS TO AN 18 KM SECTION ALONG THE WEST "LIMB OF THE GREAT DYKE SYNCLINE, FROM TOWN OF KILDONAN, S" TO SOUTH LATITUDE 17 DEG. 30 MIN.
