AZ /Fed politics are sooo crazy now, and those leases were somewhat expensive. Briscoe has to decide how our tight money is best spent. I bet he has talked to other stake holders in the area, and few of them are keeping all their positions.
My recollection is that the breccia pipes- which are the real high probability targets were about 350 in number. The other claims were much less promising. Just speculation- and we'll have to check this out- but I suspect the 400+ claims that were kept would include these high value targets. These are the pipes that they began drilling with XState. That project was abandoned not only because of the decreasing price of uranium, but because Xstate's drill broke and they ran out of money and stopped drilling before they ever got to the depth where the uranium was expected. So I suspect these valuable claims would still be in our hands.
