Exactly a 50 year lease, that was probably what made the deal more attractive in the first place, the puzzle is looking clearer by the day. If pak had an interest (personal or family/friend) in the private land a 50 year income above the possible income generated through the smelter would of sweetened the deal. We do know Pak is the main man of Kupang with royal bloodlines so they would own more land than the majority in the area.

Lets hope he is still proceeding with the investment of $10M USD. This is why I think he may be renegotiating for a better price because of loss of potential income. GMC is on the back foot now so pak (if he is the only interested large investor) can name his price and save a tonne of cash whilst taking a substantial chunk from the company.
