Trouble, for the Greedy ones looking to get it all, is that currently we are focused on the known Known Really Hot Spot(s).
There will be others.
But in this Industry you go with what you KNOW/HAVE. And look for what you expect to Know/Have.
And thus, the focus now is on getting what is Known Going. As into the Minable Category.
All the yet to be Known Unknowns will take the Multi-generations it has taken the likes of Sudbury to also get Going.
Also note that there is Two if not Three (or more once the current Exploration results are released) KNOWNS presently. These Knowns are no longer Unknown. Just owned by as many separate Companies.
And the liklyhood of yet a Fourth Known (UC) looms Very Large.
How many other Knowns will ultimately be Known. This will be Unknown by the likes of me. I will likely only live for 100 years. The Unknowns will become Known for much longer than that.
That I KNOW!
