Thanks for the info Nobear.
One interesting point from your comments is the portion dealing with "shall be based on the genuine value of the investment or returns expropriated immediately before the expropriation or at the time the proposed expropriation became public knowledge, whichever is the earlier".
In previous posts it seemed to me that the assumption was that compensation would be partially based on the price of gold at the time that the environmental permit was denied back in 2008. In my view the expropriation occurredwhen the MOC was withdrawn in February 2011 implying a much higher price for gold and subsequent substantial increase in the estimate for possible compensation.
Any thoughts on this from the members of the forum?
