One big factor everyone is overlooking is the rehabilitation cost for Nifty.  The reason it was so cheap to buy was they had to pick up this liability and now there will be some pushing to start spending money in this area (Birla certainly didn't spend anything here and there were issues even back in the WMC days with a leaking leach pad).  There is significant exposure here for the leach pads, the pit, waste dumps, the old SXEW plant plus the site in general.  Unless there is some significant turn around, they will have trouble getting any form of a buyer interested.  Also, don't forget that Nifty is subject to a state agreement, not just under the Mining Act.
Renison is an old war horse and will produce for many years to come.  Rentails will be an issue though as they have left this too long and the new tails dam will now likely not be large enough to facilitate the retreatment strategy proposed,
Just my thoughts
