Alliance Resource Partners, L.P. Announces Resumption of Production Operations at Pattiki Mine

Business Wire, July 21, 2005

TULSA, Okla. -- Alliance Resource Partners, L.P. (Nasdaq:ARLP) today announced that its wholly-owned White County Coal, LLC subsidiary ("White County Coal") has initiated production operations at the Pattiki mine located near the city of Carmi in White County, Illinois. The Pattiki mine was temporarily idled on June 14, 2005 following the failure of the vertical conveyor belt system used in conveying raw coal out of the mine. (See ARLP Press Release dated June 17, 2005.)

White County Coal's efforts to repair the vertical belt system were sufficient to allow it to perform a full test of the system yesterday. After evaluating the test results, the vertical belt system was cleared for use and the Pattiki mine resumed initial production operations early this morning.

White County Coal is an underground mining complex that employs approximately 280 workers. The Pattiki mine produces high-sulfur coal from the Illinois No. 6 coal seam utilizing continuous mining units and room-and-pillar techniques. Prior to the vertical belt incident, production from the mine during 2005 averaged approximately 255,000 tons per month.
