Antelope Coal Mine

Antelope Coal Mine is fifty-five miles north of Douglas, Wyoming in the Powder River Basin. Rio Tinto Energy America acquired the mine in 1993 from Northern Energy Resource Company, a mining subsidiary of PacifiCorp. Antelope’s production has continued to increase each year for the last 20 years, and is permitted to mine 36 million tons of coal annually. Coal mined from Antelope is shipped primarily to Illinois, Oklahoma, Michigan, and Texas. The coal's average quality is 8,850 Btu subbituminous thermal coal.

In 2008 Rio Tinto spun the most significant of its Powder River Basin coal assets -- including the Antelope Coal Mine -- off into Cloud Peak Energy, a company in which Rio Tinto has a 48.3% stake.

In April 2010, the U.S. Bureau of Land Management approved the sale of coal reserves in the Powder River Basin next to Cloud Peak Energy's Antelope Mine. Cloud Peak Energy Inc. wants to mine an additional 430 million tons of coal reserves at the surface mine. Groups questioning the Antelope mine expansion included the Sierra Club, WildEarth Guardians, Defenders of Wildlife, Clean Energy Action and the Powder River Basin Resource Council. All said the coal would contribute to climate change once burned, and that the BLM is not taking this into account when determining federal coal leasing.

In the record of decision for the Antelope mine, BLM officials said the options for limiting greenhouse emissions are better evaluated at power plants than at coal mines.

Cloud Peak Energy to ship more Powder River Basin coal to Asia
In June, 2011 Cloud Peak Energy signed a 10-year deal to ship basin coal to Asia from a port on Canada’s Pacific Coast. Cloud Peak Energy Inc. signed the deal with Westshore Terminals to ship coal through its Westshore Terminal in Vancouver, British Columbia. The company shipped 3.3 million tons of coal through the terminal to Asian customers in 2010. Cloud Energy operates the Antelope Coal Mine, Cordero Rojo Mine, Spring Creek Mine and Decker Mine in the Powder River Basin.

Cloud Peak wins bids to expand Antelope mine
On June 3, 2011, Cloud Peak Energy placed a successful bid for the West Antelope II North Coal Tract, which was previously nominated by the company’s Antelope Coal Mine. The bid for the lease sale was $297.7 million, or approximately $0.85/ton, based on the Bureau of Land Management’s (BLM’s) estimate of 350 million mineable tons. The West Antelope II Lease by Application (LBA) is subject to pending legal challenges filed by environmental organizations against the BLM and the Secretary of the Interior.

President and CEO of CPE Colin Marshall said: “This tract is expected to more than double the reserves at the Antelope mine and, along with the additional coal within the State of Wyoming lease, add about 12 years of production.”

On June 15, 2011, CPE successful bid for the West Antelope II South Coal Tract, which was previously nominated by the company’s Antelope mine. The Bureau of Land Management (BLM) estimates this tract contains approximately 56 million tons of mineable coal. CPE successfully won the lease sale with a bid of approximately $49.3 million, or $0.875/ton, based on the BLM’s estimate of 56 million mineable tons.

Not including the new PRB leases, at year-end 2010, Cloud Peak’s Antelope mine had an estimated 252 million tons of coal reserves, and the company had an estimated total reserve of 970 million tons of coal.

Federal Court Rejects Challenge to 400-Million Ton Coal Lease in Wyoming’s Powder River Basin
On August 1, 2012 a Federal District court judge in Washington, D.C. ruled against environmental groups WildEarth Guardians, the Sierra Club and the Powder River Basin Resource Council’s challenge to the BLM's decision to lease more than 400 million tons of coal to Cloud Peak Energy, the current operator of the Antelope Coal Mine in Wyoming.

The case was the first in a series of lawsuits brought by the conservation groups over BLM’s coal leasing program in the Powder River Basin. The groups were disappointed with the decision but vowed to continue legal and other efforts to challenge BLM’s coal leases.
