it wont go to zero - the company has assets and contracts the can be sold of if it ever goes into administration.
I would say the company is worth around 16c - 22c but for it to break through 22c... its going to need the help of institutional investors... and i can not see and institutional investors looking at this company given the other great companies there are out there.
at least not in its current state.
i can name 50 better speculative stocks than HIL.asx of the top of my head.
