Theories

Massive sell down today. Buy why? Obviously there has been insider info for a while with sellers getting out without collapsing the SP.
Perhaps:
(1) Big problem with regulatory approval - months and $$$ to fix
(2) Early BFS results showing poor profitability
(3) BFS to be delayed until 2015
(3) Failure to secure favourable sales contracts.

Whatever is going on we have now seen a sustained substantial unexplained fall in the SP and the company needs to provide information on the reason for that - if they can.
