I agree Lanny but may I offer a weak possible answer to your thoughts. AD and a couple of others on the board are not exactly spring chickens and maybe they are hoping that diamonds prove to be a 'guys' best friend. Assuming that they find a load of perfect blue-white sparklers, it would take years to develop a significant hope for diamond find, which as we know is not their expertise to begin with.
In conclusion, I submit that for both age related reasons and that they are not 'diamond guys', that they will sell off that phase of the venture as quickly as possible. As a guess, it will still take them a few years to bring it all together "IF" they ever find anything worthwhile. Those years would be better spent working toward a buyout of the rest of the project.

P. S. I wonder if AD polished up that diamond and gave it away as a present or if he is sporting a sharp looking pinky ring .
