Researchers have hit on what could be the largest reserve of helium in North America at a drill site in Minnesota.
Resource exploration company Pulsar Helium, Inc. has a drilling rig located just outside of Babbitt in an iron-ore mining district known as the Iron Range, which stretches 175 miles (280 kilometers) across northern Minnesota. The rig first broke ground at the beginning of February and made the discovery just over three weeks later, as the drill reached a depth of 2,200 feet (670 meters) in the early hours of Feb. 28, according to a statement.
