Lepidolite is the mica form of lithium and isa bit more expensive to process if it can be processed at all, micas are, ill say it in a way everyone can understand it, a bitch to separate from the lithium particles. Theyre harder to crush and the also float as they're a lighter mineral, Im not a metallurgist but im pretty sure im on the right track with that.

Im no lithium expert, POS look like a good buy even at 4.4c, I wish i had more money to play with but Ive got my money elsewhere for the time being, in saying so will keep a close eye on POS. goodluck to all.
