Sub-economic copper is not good, it is not special, and mines are not made of it, it's called sub-economic for a reason. Olympic Dam has many things including sub-economic copper, if all it had was sub-economic copper it would not be a mine. It is a mine because it contains economic deposits of gold, silver, copper and uranium. If you think that because RR had sub-economic copper this means that it will somehow become a minable deposit like OD you are thoroughly deluding yourself.
