Been busy perusing TGS reports and updates and the supply chain is hardly mentioned.
So looked at google earth for a bit and I'm amazed that Kipoi seems to be at least 1500KM
from any port and that's transiting a few other countries.
So the question is how do they get 500 tons of copper per week to market economically?
I guess 50 ten ton trucks running continuously could do but... surely not.
