Unless you can tell us, with your vast experience in chemical engineering, exactly how long the final 3 stages of this process to potentially produce BG Li should take... then I suggest you take MM's advice and step away from the computer.
Quite simply there is one man on earth who knows exactly how long this will take before an announcement so speculating with"somethings wrong" "it should've happened by now" aren't helping anyone.
I get my confidence from a fully designed and costed stage 2 plant, which would cost a pretty penny to make. That's what sold me on this share, that this Ann will be a formality to secure funding.
