Backstory is they need money develop/finish projects that they already blew a lot of money on. And we aren't talking chump change either ($500+ million). Short term (<1 year) no bankruptcy worries. Long term 1+ years out it is a possibility if they don't sell assets or raise money.
They are now probably going to be facing delisting about 30 days from now. There is news coming on April 6th I believe on the arbitration in their Greek mines. That a alone could shoot this back north $1. Its a high risk vs high reward situation. Any delay on the arbitration and things will get even uglier.
