Warick Grigor in my opinion has never dropped a Miner in the mix of his major talk like this that he does not honestly already own or is in talks to own or is potentially advising or is researching.
He knows how much his words have weight and is very clear-mind and calls it the way he sees it.
The Fundies follow him so I expect as this news is verified over the next few days and weeks some heavy long-termers will be showing up.
