Perhaps they should contact Gratomic?  They have a vein graphite mine in Namibia and now Brazil.  They are aggressive and bold in their advancement. They are jealous of NOU's jurisdiction but not of their deposit.  Zen has a world class deposit and could also benefit from anode materials sales thru another party.  Why not add another revenue stream that is more guaranteed than medical devices etc?????
