I get the feeling that the webinar will attempt to address the elephant in the room (i.e. the lithium) both at the beginning and at the end of the webinar; the former being just a couple of sentences about how the lithium will be mentioned at the end, and then just something small at the end to tide everyone over.
The main event is the LOMP. I suspect that 90% of the LOMP piece will just reiterate what we already know, with a few nuggets (no pun intended) thrown in for keen-eared listeners. Probably not enough to act as a catalyst, but enough to keep holders and Sprott trusting the plan.
That said, there's an outside chance that we might get an announcement a day or so prior to the webinar. In that case all bets are off.
