Sure you're a long term "Zenner"! Lol
The exfoliation method developed will be useful when ZEN mines their property, but not the reason why the stock has risen. However, a long time "Zenner" like you would know that. Lol
I suggest you research their IPs, their Ink to be used on masks/Hvac systems and the antibiotic potential of their product. This is where there is huge potential, patents submitted and the exfoliation method has minimal effect on the potential. You would think a long time "Zenner" would know all that, but perhaps you just forgot? Lol
