ArcelorMittal disclosed certain information regarding mineral reserves during “Investor Day” presentations on September 23, 2011. Such information is included herein.

Methodology

The reserve calculations were made based on SEC Industry Guide 7 and Canadian National Instrument 43-101 standards. Updated life of mine plans with discounted cash flows were prepared to support demonstration of economic viability for all ore reserve estimates. The ore reserve estimates were prepared under the supervision of ArcelorMittal qualified personnel. Detailed independent audits are conducted on a regular basis. Tonnage and grade estimates are reported as ‘Run of Mine’. Tonnage is reported on a wet metric basis. ArcelorMittal owns less than 100% of certain mining operations; the estimates have not been adjusted to reflect lesser ownership interests. Certain figures presented in the tables in this annual report reflect calculations based upon the underlying information prior to rounding and, accordingly, may not conform exactly to the figures that would be derived if the relevant calculations were based upon the rounded numbers.
