Correct - there are loads in places like Chile but people aren't very supportive about trashing the environment to access them.
History shows that any "shortage" of a strategic material is quickly followed by the development & discovery of new resources and the development of alternative technologies (eg using AL rather than Cu)
A classic is the post war uranium "boom" - it was a rare mineral but by the late '50's so much had been found it led to a collapse in the price and closure of lots of mines.
