Enough for this company to keep operating? I am very new to this so please pardon my naivety.

What does it cost to explore and extract Uranium? How does this company actually start earning any money, if it isn't sellign anything? Does it raise more capital buy selling more shares? Is that the only means of capital raising?

I have read the recent presntation over and over again, it looks very promising, but don't you need a lot of money to actually get to a full operational phase?
