Question for those who have contributed a thorough economic estimate on ZEN.

Just looked at NioCorp's announced PEA to learn and their stock dropped 22.52% to close at $1.17 after the announcement with key facts below. And they have a signficant off-take agreement, I believe for 50% that was mentioned on BNN.

Anyone have any thoughts how good the Zen PEA has to be (verus what you think it will be) to support at $3 or $5 or $10 SP after ZEN PEA announcement (whenever it happens)? Is it the PEA that matters or the institutional investor/off-take/buyout type arrangement that may follow (or come before)?

Very interested in opinions and discussion on these points as I wait patiently long. I figure these thoughts would be interesting for all as we wait.
