RHINO RESOURCE PARTNERS TO RESUME

PRODUCTION AT ITS EAGLE NO. 1 MINE

LEXINGTON, KY  (April 8, 2011) — The United States Mine Safety and Health Administration (“MSHA”) has just terminated two imminent danger orders issued on March 18, 2011 to Lexington, Kentucky based Rhino Eastern LLC, a 51%-owned subsidiary of Rhino Resource Partners LP (NYSE: RNO), regarding its Eagle No. 1 Mine in Bolt, West Virginia.  Today’s actions by MSHA allow Rhino Eastern LLC to resume production at the Eagle No. 1 Mine immediately.

R. Chad Hunt, P.E., Vice President of Rhino GP LLC, the General Partner of Rhino Resource Partners LP and the executive who oversees the Rhino Eastern Mine, commented that “We have successfully drained the pools of water that caused MSHA to issue the two imminent danger orders and we will continue to monitor the situation and drain any smaller pockets that remain when we encounter them.  The safety of our workforce always has been, and will continue to be, our top priority.  We are very appreciative of the hard work our management and workforce put into this effort to get the orders lifted and the cooperation we received from MSHA.”  Future production is not anticipated to be affected by the temporary idling of production or the engineering solution implemented by Rhino Eastern LLC.
