So from these values how would you determine a maximum possible share price. For instance, from what you are saying it will be a fairly high profit business if everything goes well.

They own 25% of $3.8b = $950m.
If they were to mine it over a 5yr period then it would be $190m per year of revenue, and lets say they make 70% profit then it will be $133m of profit each year. As they have no assets then the company value can only be related to this figure?

So using $133m, they have about 145m shares outstanding? in which case a max price per share would be about $0.92.

Is this sort of logic right?

Also, this is assuming uranimum prices will stay at the current high levels.
