After Bravo Dome?

I own the mineral rights for my great-grandfather's 400 acre homestead in Harding County. My late father had entered into an agreement in the 1980s to lease to the "Bravo Dome" project. I note in is files that there was a class-action lawsuit that resulted in a very small settlement back in the 1990s. Has there been any other activity in this area? Thanks for any input!
