This season, a big deposit away from unusual-planet minerals try discovered within the Kvanefjeld inside southern area Greenland, that is a keen autonomous region away from Denmark. Inside the 2024 American Rare Earths Inc. expose you to definitely the reserves close Wheatland Wyoming totaled dos.34 billion metric loads, possibly the earth’s prominent, and you can larger than an alternative 1.2 million metric flooding put in the northeastern Wyoming. One to mine might be able to create as much as 7,two hundred metric tons of ferro niobium and you may 95 metric a lot of scandium trioxide a year. The full structure between the two nations might have been authored on the the new Australian Service of Globe, Research and you may Resources webpages.
