  • Wyoming coal mines cut production, jobs due to weak demand

    May 2, 2012

    Three coal mining companies in Wyoming’s Powder River Basin are cutting back operations due to a decline in coal demand from a warm winter and utilities moving away from coal to cheap natural gas. Peabody Energy Corp., which operates the North Antelope Rochelle, Caballo and Rawhide mines in the Powder River Basin, reduced its contact labor and temporary workers last week, totaling less than 2 percent of its Powder River Basin workforce. According to reports referring to federal employment data, cuts are estimated to be around 40 workers.

    Cloud Peak Energy, the operator of the Cordero, Antelope and Decker mines in the Powder River Basin, stated they are closely managing overtime and reducing use of contractors while trying to avoid buying new equipment. St. Louis-based Arch Coal announced Tuesday it would further curtail production for the year by idling three draglines by the middle of the year. It’s not yet clear how the decrease in production cut will affect jobs, said Kim Link, spokeswoman for Arch Coal.

    BLM accepts $49M bid for Powder River Basin tracts

    June 20, 2011

    Cloud Peak Energy, Inc. has won its second coal lease in two months, doubling the mineable coal available to its Antelope Coal Mine. Cloud Peak won the coal-lease sale for the West Antelope II South Coal Tract in Converse County, Wyoming, bidding $49.3M dollars for its estimated reserves of 50M mineable tons. In May, Cloud Peak won the lease-by-application for the West Antelope II North Coal Tract in Campbell County. CEO Colin Marshall estimated the pair of leases should add a dozen years onto the life of the Antelope mine.

    As part of the agreement, Cloud Peak is required to pay rent of $3/acre each year, and then additional royalties on each ton of coal mined. The royalties are then split between the federal government and the state of Wyoming. The lease sale is being challenged by WildEarth Guardians, an environmental group that has criticized the fact that the Powder River Basin does not follow federal laws governing coal producing regions even though it is the largest coal-producing region in the country. WildEarth is also expected to challenge two other Campbell County coal-lease sales coming up in July and August.

    Cloud Peak Energy Wins Wyoming Coal-Tract Lease For $297.7 Million

    May 11, 2011

    Cloud Peak has announced that it has won its bid to expand its Antelope Mine. It’s bid of nearly $300M dollars was accepted by the Bureau of Land Management for the West Antelope 11 North Coal Tract. The tract is estimated to hold 350M tons of coal, and will double Antelope’s reserves and add 12 years of production onto the mine’s life. Cloud Peak has already made its first payment of nearly $60M for the tract.

    Under the Lease By Application rules, Cloud Peak requested the BLM lease West Antelope 11 North, specifying the exact size, shape and location of the tract. No other bids were made on the tract.

    BLM to offer four Powder River Basin coal leases

    March 22, 2011

    US Secretary of the Interior Ken Salazar and Wyoming governor Matt Mead jointly announced the decision to open for leasing two large tracts in the Powder River Basin, releasing 758 million tons of coal for leasing in the next few months. The lease, bonus bigs and royalty payments should generated between $13.4 to $21.3 billion dollars, of which Wyoming would get almost half. Each of the four were “leases by application” where an existing mining company requests that land adjacent to their mine be opened up for lease. In such cases, there is usually only a single bidder, although the US Bureau of Land Management can reject the bid as insufficient.

    The four announced leases are:

    • May 11, West Antelope II North, 2,838 acres/350M tons of mineable coal, filed by Antelope Coal LLC, adjacent to the Antelope Mine.
    • June 15– West Antelope II South, 1,909 acres/56M tons of mineable coal, filed by Antelope Coal LLC, adjacent to the Antelope Mine.
    • July 13 – Belle Ayr North, 1,671 acres/222M tons of mineable coal, filed by Alpha Coal West.
    • August 17 – Caballo West, 1,024 acres/130M tons of mineable coal, filed by Caballo Coal Company. The Caballo West and Belle Ayr tracts touch each other and fill in the gap between the Belle Ayr Mine and the Caballo Mine.

    Cloud Peak Energy officials optimistic about boosting coal exports to Asia

    November 28, 2010

    Officials from Cloud Peak Energy, the third largest coal producer in the country, say that their coal exports of 3M tons this year will be almost double those of last year, and that as terminals on the west coast are built, there is a huge potential for future growth in coal sales due to the huge industrial growth in Asia. Currently Cloud Peak exports through the Westshore facility near Vancouver, B.C.; however that port is already at capacity.

    BLM plans PRB coal sales in face of environmental opposition

    Washington (Platts)–5Aug2010/515 pm EDT/2115 GMT
    The US Bureau of Land Management plans to go ahead with the sale of more
    than 350 million short tons of coal in the Wyoming Powder River Basin, despite
    objections and at least one planned lawsuit from environmental groups.

    The BLM will set a date for the lease sale at a later time, according to
    a notice to be published Friday in the Federal Register.

    The BLM is set to issue its record of decision for the 130-million-st
    Caballo West tract being sought by Peabody Energy, one week after releasing a
    decision for the 222-st Belle Ayr North lease applied for by Alpha Natural
    Resources. The two leases cover more than 2,700 acres south of Gillette, and
    would add to the life of Peabody’s Caballo and Alpha’s Belle Ayr mines.
