It is usual in this mineral exploration business that a company relinquishes mineral claims that are non-core assets or claims that are less prospective or claims on which it would cost too much to prove a mineral resource. Or claims that might have permitting problems down the road.
It's a business. You let some go but then you stake other claims. Or you get into option agreements on some other claims.
Anyway NBRI has maintained all their core assets. They can still sell and option some of their better claims.
