Belly-up or bottom drawer?

Could MACA go belly-up, if iron ore slips and settles around $40/tonne (goodbye AGO and other contracts) AND if Beadell contract fails to pay? Or can it survive on civil and other work until the good times return (say 2 to 3 years). A measured response from someone with knowledge of the industry would be greatly appreciated.

If the answer is yes, then may as well jump ship now. If no, put certificates in bottom drawer (maybe even grab a few more at around 50c if it goes there) and reap the benefits down the track.

I'm leaning towards bottom drawer - but hope springs eternal ...
