Another consideration is appeasement of well know Nab gov fears that on granting of a mining license, the whole box and dice won't be sold out from under the their nose as with with the much maligned deal between Dattals and Areva. I don't see the Chinese needing to offer anything to the Nabs for any other reason. Anyone else eying EXT will probably follow suit, and possibly even up the anti so that there are TWO auctions, one for EXT and one for NAB Gov favor. The latter needs a premium to the price paid for EXT/KAH to ensure enough stock is acquired for the 10% palm-grease.
