I know ZEN has mentioned a steady stream of NRs over 3 weeks ago, and so far nothing yet. I really hope it won't be via a "presentation update". :)
The one piece of news i hope they report on, is the proprietary purification process they develop. And, if they do, i hope it has the same type of "time" gains that Enirgi Corporation achieved with lithium extraction (processing time reduced from 500+ days to 24hrs or less).
