I wouldn't hold your breath on seeing the metal divisions split up via stock. KXL's style is to create value out of underexplored properties. Gold is clearly where it's at now - other metals later. They would likely prove it a ways before any split.
I would suggest doing with KXL what I did today with other stocks - buy just a bit, and suddenly you're paying much better attention to it. If you see your position going down and up, you remember the "why" essentials a lot better.
I have a hunch that the price now will soon look cheap. KXL seems pretty clear about doing exactly the right things (i.e. big meaningful meaty releases) to sustain the share price over the level that PP investors bought in at last Fall.
The base on this stock has been very solid so your risk is likely limited, but of course do your own DD (and all those other lawyer words).
