Although Mesabi Nugget Delaware, LLC (Mesabi Nugget), an affiliate of Steel Dynamics, Inc., is not a mining operation, the MSHA claims jurisdiction over Mesabi Nugget's operations regarding the production of iron nuggets via a production process that utilizes iron concentrate and coal as input raw materials. Therefore, this disclosure relating to Mesabi Nugget is being submitted by Steel Dynamics, Inc.

The MSHA citations and orders set forth in the table above are those that were issued by MSHA and received by Mesabi Nugget during the year ended December 31, 2011. In addition, the table above sets forth the total dollar amount of assessments proposed by MSHA during the year ended December 31, 2011. The dollar amount of MSHA assessments proposed does not include assessments on those citations or orders that were received by Mesabi Nugget after December 31, 2011.

The information in the table above does not reflect any subsequent changes in the level of severity of a citation or order, or changes in the value of an assessment that occurred during the time period presented in the table above (or that may occur after the time period covered in the table above) as a result of proceedings conducted in accordance with MSHA rules. For purposes of legal actions disclosures in the table above, any citation contested in any form or manner with MSHA is considered a legal action for reporting purposes.

During the period covered by this report, no written notices were received from MSHA of a pattern, or the potential to have a pattern, of violations of mandatory health or safety standards that are of such a nature as could have significantly and substantially contributed to the cause and effect of mine health or safety hazards under Section 104(e) of the Mine Act, and there were no mining related fatalities.
