Not saying that you are bashing ZEN, but really its an early stage mining stock, graphite to boot, how often are all questions ever answered at this stage.
What I like is:
1) Large deposit almost 1.5 million tons of product at 100% recovery, so even at only 66% its 1 million tons
2) Company has already shown they can purify to 99.9%
3) Hydrothermal with properties as good or better than synthetic
4) Great team
5) Great location
For me this is already a winner. Seems like a lot of people want to create doubt these days, ok by me, I am staying long.
