Thorium
Thorium is used in aircraft engines and rockets, due to the fact the metal imparts
high strength and resistance at elevated temperatures. Thorium can also be used as nuclear power-based electrical power generation.
Therefore, Thorium is evidently due to become an important resource in the future.
Although readily available throughout the World,
it is also possible to mine Thorium in South Africa.
