Massive buying before the resource update when I bought on the fact there was so much buying going on and then sold the next day. (I would think that is loose lips from MMX) Now we have a fairly decent sell off today with a trading halt a few hours later than the market opened. What does this suggest to me... either a) There is some truth to Mitsubishi's committment or b) Something else has come into play that we don't know about. Either way, this will be an interesting announcement
