I think though if they buy out the remaining 25% it should cost more than 25% of the in situ value of the minerals because it is strategically important to them to get the whole deal up front. They don't want to end up with the earn-back 75% deal only.

Wouldn't that put us in a stronger negotiating position especially if they want to do it quietly before allowing the market to negotiate? I would almost want to make the deal on the 25% before I declared my intention to earn-back 75%. That is possible.
