RE:Casino Mining .com Yes, Casino is a private, non-traded arm of WRN, which is a publically traded. Both arms serve completely different functions. WRN is about explorations and mining. WRN deals with a lot of work with people outside, especially outside the Yukon.
Casino works with public relations within the Yukon community. That's why you see more gender balance/ethnic diversity in Casino Mining: 5 women (3 FN, one local non-FN, and one East Indian/Canadian expert mining researcher we plucked from Hermosa). Jay Corman, Dale's son, also is a part of Casino.
After the buy out, WRN will likely disolve following a short transition, Casino will not. Casino will stick around to support Rio/MMC.
Also, I believe a third spin out company will likely be formed after WRN dissolves. Us shareholders will likely have the option to shares in x spin out if we so choose.
