For anyone holding a lot of $$ in McF stocks, holding a bit of FNC would be fine. For me, that would be something less than 10% of my NOT holding. If you have a very small amount of money in the game, there is also nothing wrong with gambling it all on one high-beta stock like FNC, I would never suggest it is not good value in that context. The logic is that if NOT has a world class mineable deposit, it is going much higher, and if it does not, FNC's "deposit "will almost certainly not be mineable. Personally, I am assuming FNC will hit mineralisation, but I still come to the same conclusion.
