Rare Earth elements are more in demand now than at any time in history, and for good reason. China produces almost 95% of ALL
rare earth elements used in industry today, and they recently declared that they would no longer ship these valuable commodities out of their country, preferring to use them in their own industries. This places China in the drivers seat in this space, as they literally attempt to corner the market for REE's. However, a number of western countries and companies are now earnestly in the hunt for these highly valued elements.
