i understand everybody is waiting for the lithium assaysbut to be honest i bought this for the tantalum and the lithium is a bonus for me.raw tantalum trades for about $350.00 a kilo and refined tantalum can reach north of $700.00 a kilo .so if you count it by tonne like they do lithium ,thats 700,000.00 a tonne.and if you compare where tantalum is used you will understand the value of it.
