As they are secure creditors they can accept any price as long as the selling of the mine isn't a conflict of interest, i.e. they sold it to themself or another entity that they are involve with as this could be good grounds for legal action, mind you it didn't stop them attempting to put in a Noteholder bid of $50M USD 2 years ago which was rejected by the other secure creditors.
So if they do this and sold it without any conflict of interest, there is nothing we or the substantial share holders who aren't secure creditors can do.
We know these major creditors are still substantial share holders with majority holders with at least over 50% of the O/S (hence always had control the mine) so it's in their best interest to sell mine as high as possible.
