Patriot Coal 10-Q 2011 Q2 Quarterly report

Exhibit 99.1

Mine Safety Information

On July 21, 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Act) was enacted. Section 1503 of the Act contains new reporting requirements regarding coal or other mine safety.

Patriot is committed to providing a safe workplace for all of our employees. We continue to engage proactively with federal and state agencies in support of measures which can legitimately improve the safety and well-being of our employees.

The operation of our mines is subject to regulation by the federal Mine Safety and Health Administration (MSHA) under the Federal Mine Safety and Health Act of 1977 (the Mine Act). MSHA inspects our mines on a regular basis and issues various citations and orders when it believes a violation has occurred under the Mine Act. We present information below regarding certain mining safety and health citations which MSHA has issued with respect to our coal mining operations. In evaluating this information, consideration should be given to factors such as: (i) the number of citations and orders will vary depending on the size of the coal mine, (ii) the number of citations issued will vary from inspector to inspector and mine to mine, and (iii) citations and orders can be contested and appealed, and in that process, may be reduced in severity and amount, and are sometimes dismissed.

The table below includes references to specific sections of the Mine Act. We are providing the information in the table by mining complex because that is how we manage and operate our business. The information in the table reflects citations and orders issued to us by MSHA during the three and six months ended June 30, 2011, as reflected in our records. Due to timing and other factors, the data in our system may not agree with the data maintained by MSHA.
