Alliance Resource Partners, L.P. (NASDAQ: ARLP) today announced that Alliance Coal, LLC, its wholly-owned subsidiary, has completed the previously announced acquisition of substantially all of the coal related assets of Green River Collieries, LLC ("Green River") located in Webster and Hopkins Counties, Kentucky. (See ARLP Press Release dated February 24, 2012.) "The acquisition of Green River provides an attractive addition to ARLP’s existing operations in the growing market for Illinois Basin coal," said Joseph W. Craft III, President and Chief Executive Officer. "Ongoing expansion of scrubber capacity by U.S. utilities supports our view that demand for Illinois Basin and Northern Appalachian coal will continue to increase. We remain committed to ARLP’s mission of creating exceptional value for our unitholders through sustainable cash flow growth and increases in unitholder distributions." The transaction includes an estimated 40.0 million tons of coal reserves in the West Kentucky No. 9 coal seam and the Onton No. 9 mine located near the city of Sebree, Kentucky. The underground mining complex currently operates three continuous mining units employing room-and-pillar mining techniques. An air shaft is currently under construction which would allow the addition of a fourth continuous mining unit should market conditions warrant increased production from the mine. Over the balance of 2012, ARLP currently anticipates the Onton No. 9 mine will produce approximately 1.5 million tons of coal, essentially all of which is committed and priced under contracts with existing ARLP customers.
