Scandium, because it has a much smaller ionic radius than the REE Group, and promethium, due to analysis limitations, are not included in the TREO. The conversion from element to oxide group is as follows:

TREO = HREO + LREO

MREO = Dy_ppm*1.1477 + Nd_ppm*1.1664 + Pr_ppm*1.2081 + Tb_ppm*1.1761

HREO = Dy_ppm*1.1477 + Er_ppm*1.1435 + Eu_ppm*1.158 + Gd_ppm*1.1526 + Ho_ppm*1.1455 + Lu_ppm*1.1371 + Tb_ppm*1.1761 + Tm_ppm*1.1421 + Y_ppm*1.2699 + Yb_ppm*1.1386

LREO= Ce_ppm*1.1712 + La_ppm*1.1727 + Nd_ppm*1.1664 + Pr_ppm*1.2081 + Sm_ppm*1.1596

Some uses for other rare earth elements include:

| ● | Yttrium: Used in radar systems and superconductors.                             
 The U.S. is 100% import-dependent, with 94% from China.                         |
| ● | Neodymium: Critical for permanent magnets used in                               
 electric vehicles, wind turbines, and drones. China controls 70% of production. |
| ● | Terbium: Essential for lasers and sonar systems. China                          
 controls 90% of global supply.                                                  |
| ● | Dysprosium: Used in magnets for drones and wind turbines.                       
 China supplies 85% globally.                                                    |
