Public Company Information:

"Hitting one billion tons of coal shipped is quite an accomplishment for the Cordero Rojo Mine. We are proud to help America meet its energy needs for safe, reliable and affordable electricity."

GILLETTE, Wyo.--(BUSINESS WIRE)--Cloud Peak Energy announced today that the company’s Cordero Rojo Mine, located in northeastern Wyoming, will ship its one billionth ton of coal in the coming days. The mine sold approximately 36.7 million tons of coal in 2013, ranking it as the third largest coal mine by production in the U.S. last year. Since 2005, the mine has paid more than $1 billion in taxes and royalties to federal, state and local entities.

“Achieving the one billion ton milestone is a testament to the hard work and strong focus on safe and responsible production by Cordero Rojo Mine’s employees,” said Colin Marshall, Cloud Peak Energy’s President and CEO. “Cordero Rojo will continue to play an important role in U.S. coal production well into the future.”

“I want to congratulate all of our employees on reaching this significant mark,” said Joe Vaccari, Cordero Rojo Mine General Manager. “Hitting one billion tons of coal shipped is quite an accomplishment for the Cordero Rojo Mine. We are proud to help America meet its energy needs for safe, reliable and affordable electricity.”

Started in 1976 by Sun Oil Company, the Cordero Mine shipped just over 10,000 tons in its first year of operation. The Cordero Mine merged with Caballo Rojo Mine in 1997, to create the Cordero Rojo Mine. Since merging the two mines, the complex has historically produced over 35 million tons annually. Cordero Rojo recently received the Wyoming Governor’s Summit Safety Award in the Large Mine Category presented by the Wyoming Department of Workforce Services, Mines Inspection and Safety Division.

Cloud Peak Energy has a long-standing record of safe, responsible coal production. Last year, the company had one of the lowest All Injury Frequency Rates of the top-25 U.S. coal producers, according to MSHA.
