IVN's grade is KING of the hill folks, the others are all scambling.
IVN has average grades around 5% - 6% while others have well under 1%.
Others have to mine around 10X the rock to get the same pound of copper. So much more labour and fuel and wear and tear on all your equipment and infrastructure.
Now you tell me who is making money???
I'm betting they go on strike.
