Ann: ioneer Successfully Produces Battery Grade Lithium Hydroxide, page-49

I'll also add this. The USA's LIT Battery and technology Exchange Traded Funds are a measure of lithium demand at the retail end of the market as well as the miners and producers end.
It is a reflection of how much fans lithium is in medicine, tv, mobile phone, electronics, you name it. So many retail and primary production markets rely on it and the LIT index is absolutely booming. Forget the price of Lithium - INR is tied to that index - it is driving our price right now. While ever our dim-green light has not turned red on this mine, we will continue to grow alongside the LIT Index price. If we go bright green I believe we will triple to quadruple (at this price). If we went bright green at 50c we would double or triple, and so on.
Just my opinion, others may think way more or way less.
