Thorium Minerals - There are many 
Thorium minerals.  
Thorianite (ThO2)(Thorium Oxide) with 88% Thorium is the obvious APEX Mineral.     
Thorium is three times more abundant than Tin in the Earth's crust and is about as common as Lead.  Thorium has one of the largest liquid temperature ranges of any element, with 2946 °C between the melting point and boiling point.  Thorium is slightly radioactive (half-life equals the age of the universe) and may one day replace Uranium in nuclear reactors as a safer alternative.
Thorium was unknown until modern times.
Thorium is a component of the magnesium alloy series, called Mag-Thor, used in aircraft engines and rockets
Thorium has no known biological role.
