Vein... and Vein type are the same thing..... The fact that the grapite is forced through the rock at extremely high pressure, and temperature... it forms in veins..... this form of graphite is usually the purest.... which the testing has proven.. So you see, there is vein graphite, lump graphite, flake graphite.... what ever you require. And because of the purity, the vein commands the highest price.  Zenyatta's graphite is the purest in the world., and the cheapest methods will achieve the 99.96% purity.... Once everyone in the market begins to realize this, they will understand why we are only in the early stages of the Stock Price movement. There will be hackers and slashers , slammers and damners... by those who do not understand.. But that's what makes a market.
