Evidently the world will run out of gallium in 5 years, indium and halfnium in 10, tantalum and zinc soon thereafter.  Bad news for LEDs and RF semiconductors.

I really have to question that article's presumptions.

Russia has large platinum reserves, the cited South Africa is not the only source.
Running out of silver? Silver is a by-product of copper mining here in Arizona and in Chile...

A lot of it in NE Oklahoma but the mines have been closed and the site designated a superfund site.  The fed is buying all the property in Pitcher, OK and moving people out as fast as they can.
