It means that while LBSR itself may still issue those shares for ongoing funding concerns, the separate entity KVM no longer has the ability to buy them at steep discount and dump them into the market as the next run begins. It downgrades the potential for rampant dilution that might thwart any rise in PPS.
Also, when you consider current O/S and the fact that A/S is 1.25 billion, having over 200 million available to an outside source that can issue them at will, and at discount, means that the likelihood of those shares being issued at a time that hurts the interests of current shareholders has been diminished considerably. If Briscoe registers and issues the shares himself, he must consider if the action will harm the company and it's chances for ongoing public funding. KVM has no such considerations and would readily flood shares into the market to make a buck, regardless of whether it hurt LBSR or the retail shareholders.
And the real wild card is the possibility that this deregistration is because another more attractive source of funding has been obtained. Deep pocket JV suitor? I have no idea, but I'd love to see an announcement to that effect. Early next week would be excellent timing in light of the recent news.
