RE:RE:Interesting read Lithium is very abindant and widely distributed, from brines, to claystones and pegmatites. The claystone deposits are just paleo lake beds in an area where evaporation exceeded precipitation, perhaps with a contribution from hydrothermal fluids. We will soon be awash in lithium, perhaps as soon as three years from now. Cobalt, bismuth, and to some extent nickel are much tougher to come by.
