Nov 7 (Reuters) - James River Coal Co idled fourmore mines in Central Appalachia and temporarily laid off about200 employees as the company looks to shore up its precariouscash position amid weak coal prices.
The company's shares fell 17 percent to $1.58 after the coalminer also posted a bigger-than-expected quarterly loss and itsshipments declined.
"The balance sheet continues to be the critical issue towatch for James River Coal," Simmons & Co analyst Bill Herbertsaid in a note.
James River Coal's available liquidity plunged 35 percent to$71 million as of Sept. 30, from $108.8 million as of June 30.
If the liquidity were to fall below $50 million, it wouldamount to a covenant breach, according to terms of the company'scredit facility.
"I feel relatively optimistic about where we are right nowbut at the same time I also need to be cautionary that a lot ofagreements need to be reached and a lot of negotiating thatstill has to take place," Chief Executive Peter Socha said on apost-earnings conference call.
He said the company was in talks with current debt holdersand also other potential investors.
Tuesday's idling brings to seven the number of James RiverCoal mines shut since September, as U.S. coal miners alsostruggle with tougher environmental regulations.
James River Coal idled production at three mines in CentralAppalachia in September, and last month said about 525employees, who were put on furlough, will be laid off in thefourth quarter. ()
