Westmoreland Coal Company announced the completion of the acquisition of Chevron Mining Inc.'s Kemmerer coal mine in Lincoln County, Wyoming. Total consideration for the purchase of the Kemmerer mine included a cash payment of $76.5 million and the assumption of approximately $118.0 million in certain liabilities, including post retirement medical, pension, black lung, and asset retirement obligation liabilities. Over the last five years, Kemmerer has produced, on average, 4.8 million tons of high-quality sub-bituminous coal for sale to the adjacent Naughton power station, as well as various industrial customers located in the proximate geographic region. The transaction includes approximately 118 million tons of coal reserves as of December 31, 2011, enough for 20 years of production; a skilled and stable workforce; recently installed state-of-the-art coal preparation and loadout facilities; strong customer commitments; and an expansive fleet of well maintained mining equipment. Additionally, substantially all of Kemmerer's projected production for 2012 through 2016 is committed and priced under existing sales contracts.
