Just my opinion here... I don't believe Mark would entertain a 'straight up buyout' of the Project/Company—there is far too much time-effort-money-blood-sweat-globetrotting etc etc. for Mark to throw up his hands at this stage in development and announce a buyout!...but what I could envisage is a (percentage)-joint-venture-Partnership with a deep-pocket blue-chip Miner - where Smith and his team manages/runs the Project and the "Blue Chip Miner" funds the project (eliminating share-dilution and fast-tracking a ride to a NY stock exchange)...
Anyways just my food for thought.
(The straight up buyout card could still be in Mark's back pocket - if everything really went pear-shaped!)
there are always potential buyers lurking for a de-risked, economic junior mining companies. (Last resort) imo
