I'd expect no return. I haven't seen a mining company appointed in receiveship return dollars to the shareholders and in most cases it's a big dilution of existing shareholders to recapitalise.
The question that will be asked is, if they couldn't turn the company around for all this time, how will they do it with new capital injection and a recapitalisation.
Sorry for your lose, however I know a few people who've lost a S$^tload more.
