Rum Runner, ZEN has told people the met tests were finished. Glorieux made quite a thing about this, stating only the final edit was needed.

As for ZEN not being a graphite company anymore, I disagree completely. The only source of income for ZEN is the graphite in their pipes. They have to be able to extract it economically, reliably and with suitable purity. They have not shown that they can do this. 

This lack of upscaling seems to be having an effect on money raising. They would be remiss if they put off the release of a viable extraction scheme until they had every little variation ironed out. Show the world that getting your graphite is not a problem, then work on variations that facilitate producing your saleable end product.
