Look at the charts on this page: http://www.metal-pages.com/metalprices/lanthanum/
Looks like from Mar to Feb price in $/kg went from 10 to over 90? Stunning if true.
I identified La as a pretty good protium fusion candidate, back when the price was $10.50/kg. It really should have been at the top of my list given its ability to absorb hydrogen, and to form useful alloys.
