Kota Saint Jovite Youngblood serves as president of Youngblood Metals Mining in Monrovia, California. In addition to his work, Kota Saint Jovite Youngblood is interested in rare earth metals (REMs) and their practical uses.

Known in the science community for their benefits in the medical and technological spheres, REMs are 17 elements found in monazite and bastnasite deposits in countries such as India and Madagascar, as well as countries in Africa. The metals are not truly rare, as their name states, but they are less well known than other elements. Most REMs are more common in the earth’ crust than silver, and some are more common than copper.

One of the practical uses of REMs is turning them into heat-resistant magnets. For example, samarium, a rare earth metal, can be mixed with cobalt to form a REM magnet. A second example of a REM with a practical use is erbium, which is used in fiber optic communication cables. Other REMs include cerium, dysprosium, europium, gadolinium, holmium, and lanthanum.
