While you're there, if you come across any governmental types who are involved with mining or minerals exploitation, can you ask them if they're ready to dig up the thortveitite containing pegmatites?
In Norway, scandium is in large thortveitite deposits.
One of the few minerals having a notable scandium content is thortveitite.
The majority of scandium production comes from thortveitite deposits.
Norway, Madagascar, and the United States have thortveitite which contains from 44 to 48% scandium oxide (ScO2).
In the United States, scandium was recovered from thortveitite-rich mine tailings, like the tailings of the Crystal Mountain fluorite mine near Darby, Montana.
