A new US Geological Survey study says that only a small percentage of coal in the Powder River Basin is cost-effective to mine in the current market. According to the USGS, there are more than one trillion tons of coal present in the Basin, of which 162 billion tons could technically be recovered. Of that, it would only be economically viable to mine about 25 billion tons in today’s market.
Project Chief for the US Coal Assessment Program, Jim Luppens, says new geologic data made the study possible.
