Ann: Initial Funds Received From Sale of Goulamina to Ganfeng, page-63

You are right the ann says a 100% retutn of the net after tax proceeeds.
As you point out the costs we have put in to improve the asset should be a deduction for tax purposes.
Mali will likely not allow a tax deduction for all the money FFX spent exploring, drilling etc Goulamina even though they forced us to stump at $US60 mill as compensation because they insisted we are connected.
The compensation money $US60 mill should also be deducted from capital gains.
