[Marvel]How come Wakanda hasn't run out of Vibranium?

They've had it for 10,000 years? How did they conserve so much of it?

They are sitting on a huge amount of it, and most applications don't require that much of it.  Also, most things don't need to be remade.  That vibranium spear is gonna last pretty much forever for example.
