Iron Ore Reserves of the Mesabi Range, Minnesota.
NTIS: PB 297-162 :64 pages
The iron ore reserves estimated to occur on the Mesabi Range are tabulated by ore class and range unit. The listing of reserve tonnages does not give the grades of the material in the various classes or the probabilistic grade matrix, but shows the general distribution of materials considered to be ore in this study. The estimated tonnages of taconite ores are based on an estimate of the 1974 production costs and represents ores available in 1975. As described in the report, the reserve estimate is designed to include all taconite materials that can be produced to a no-loss situation. The tabulated reserves should include material that does not have sufficient profitability to be economic at this time.
