Unfortunately with the current situation TGS is in, we cant really see the benefit of the CDF (Congolese Franc) depreciating but it is definately there.
I remember only six months ago we were sitting at 1,000 to 1
Now we are 1,400 to 1.
To my knowledge TGS pays its workers in CDF and gets USD from sale of copper.
