3 Feet in depthThis appears to be the average , expected depth for coal deposits in West Virgina. There are many published articles that discuss the expected depth of coal deposits. I am not sure how the market will react but these values are probably what NAG expected to hit. What they don't know is how many remaining holes will come in with the same depth values.

West Virginia is known as the Mountain State, but 300 million yearsago it was a vast, featureless coastal swamp extending for hundreds ofmiles and barely rising above sea level. Geologists call this time the"Carboniferous Period." It was a time when the atmosphere wasbeing dramatically depleted of carbon dioxide (the "greenhouse gas")and vast tropical forests of primitive ferns and towering primitive treesruled the planet.
Coal seams are fossilized accumulations of plantswhich lived and died in swamps that were so devoid of oxygen that few microbesor other critters could survive to feed on their remains. The first phaseof coal known as "peat" thus developed. These swamps were interwovenwith intricate, meandering river channels which eventually covered thingswith mud and silt. Subsequent deep burial by more sediments in succeedinggeologic ages resulted in heat and pressure which transformed the peatinto coal. Generally speaking, every 12 inches of coal thickness representsapproximately 10,000 years of continuous peat accumulation. Coal seamsin West Virginia average 3 feet in thickness, although they occassionallycan be as thick as 25 feet.
Good luck to the longs
