RE:Uncertainty The cost of starting a completely new exploration and digging of a mine is 50x more expensive then to have access to previously used but discontinued mines. There's many different places in the world with graphite but doesn't mean it commercial grade graphite like Sri Lanka has.
Graphite veins in particular are the best, I'm not qualified to break it down enough but from what I've read, vein graphite is the purest and easiest to take to comercial production versus amorphus or flake which can require more work and more hands involved.
The other significant factor of vein graphite is that those veins run continuous and branch off into other veins so you can always follow a trail. If you watch those gold mining shows on TV, they dig and find a bit of golf and then have to drill and dig a new hole. Vein graphite you know you're digging graphite for sur ebecause you are following the vein.
Why I like Ceylon over the other 100 I have looked at is their allocation to the Sri Lanken land and as well there isn't limitations such as one company in Quebec I looked at, they are delayed as they found an area to mine graphite but it is first nations land etc.
Where you only have 30,000 shares and the price of those was presumably considerably low (me too), I would saw this is a low risk high reward unless you need that cash.
