NEW YORK, April 23 (Reuters) - International Coal Group Inc (ICO.N) on Wednesday reported a wider quarterly loss, partly due to production at a new West Virginia mine ramping up more slowly than planned due to labor shortages.

ICG shares fell 7 percent to $7.65 in extended trade, after falling 8 percent in regular New York Stock Exchange trade.

The first-quarter net loss was $11.5 million, or 8 cents per share, compared with a loss of $8.1 million, or 5 cents per share, in the same quarter of 2007. Revenue rose to $250.9 million from $228.3 million during the same period a year ago.

Analysts, on average, were expecting a loss of 4 cents per share, with revenue at $234.5 million, according to Reuters Estimates.

"While we had many successes, the ramp-up in production at the new Beckley complex (in Raleigh county, West Virginia) was slower than planned due to labor shortages, supplemental roof support requirements, mine plan adjustments to protect long-term main entries, and regulatory delays," President and Chief Executive Officer Ben Hatfield said.

He also said overall production in January and February lagged, although performance at most of ICG's operations showed significant improvement in March.

The company said it has strong committed sales levels for 2008, 2009 and 2010, yet retains enough uncommitted positions to allow it to benefit from further market improvement.

For 2008, it expects to sell about 20 million tons of coal at an average selling price of $51 to $52.50 per ton, up from the previous estimate of $47 to $48 per ton.

For 2009, the Scott Depot, West Virginia-based company expects to sell 20 million to 21 million tons at prices averaging between $58 and $63 per ton. Its previous price estimate was for $51 to $53 per ton. (Editing by Braden Reddall)
