Quantum Rare Earths Developments Corp. has reported they have discovered a potential huge source of rare earth elements, right in the middle of the U.S. While the USGS reports that the U.S. has an estimated 13 million metric tonnes available for mining (about 1/3 of China's reserves), finding another regular source is crucial to global stability. The potential yield of the deposit, found in Nebraska, could be the world's largest source for Niobium and other rare earth elements. Could this be the next gold rush?
