When will the Appendix 4C come out?

There was a kind of quarterly activities report that was unofficially released to the market, which may be softening the bad news
GTG's problem is that whilst a number of balls are in the air, based on their burn rate, they will run out of money before June 30, most likely somewhere around April/May, which means they need to have a capital raise soon, either publicly or privately. If they have been actively prospecting, chances are their cash burn will have increased. Be prepared to dip into your pockets again soon...It may well be worse before it gets better.
