To my knowledge, not much, but if those shares still exist, talk about 'free shares" if ENZC does hit something on a gain? They'd not burn them for no cash in-hand at ENZC these days.
They are using ENZC shares as an ATM to continue drawing cash out when they need monies to pay for their expenses. Approximately 100 millions shares were traded handed on one day last week or the week before caused ENZC PPS to dive to trip value. These preferred shares will slowly converted to common shares so they can cash them out.
