A recently discovered helium reservoir in Minnesota boasts "mind-bogglingly" high concentrations of the gas that are even greater than initially thought, potentially paving the way for commercial extraction.
Resource exploration company Pulsar Helium, Inc. announced the discovery of helium stores in late February, after a drill just outside of Babbitt, in northern Minnesota, located gas deposits at depths of 2,200 feet (670 meters). Initial measurements showed helium concentrations of 12.4% — which "is just a dream," Thomas Abraham-James, the president and CEO of Pulsar Helium, told CBS News at the time. But new laboratory readings have surpassed those results.
