It would seem that they are very close to something, waiting until the last day of the month suggests that they were unsure until the last minute on whether they would have a release ready by the deadline or not.
So I would also concur with Mother earth, that announcing today that the warrants will not be extended again suggests that
A) They fully expect to release something that will more than double the share price in the next two weeks or
B) They have found a financial resource that makes the exercising of these warrants unnecessary going forward.
Regardless, nothing negative in all this.
