If he does it is a great buying opportunity for everyone else.
The bigger risk I think is if he doesn't buy in after doing the DD on the resource. We are basically getting one of the best geos in the world to check up on what TIE has and with his opinion backed up with serious amounts of Dr Fu's own money. Given the risks to TIE if he walks after looking at the data I don't think Caigen would have agreed to this unless he is 100% convinced of the quality of the resource. This whole thing is far more bullish to me than the visible gold.
