The ore from both Enterprise mine and X41 mine is hoisted up the U62 shaft to surface. In the Mount Isa copper mine orebodies, sub level open stoping, coupled with secondary and tertiary stoping is used to extract the ore. Blocks of ore 40 m wide, 40 m long at full orebody height are removed.Dec 16, 2020 If each EV contains 85 kg of copper, that is 42,500,000,000 kg, or 42,500,000 tonnes of copper, roughly twice the current volume of copper produced by all of the world’s copper mines.
