Busy at the moment to answer this one; but to push the skateboard out; to start its not 2m tonnes or ore they move; its around 350kt of concentrate for 2,000,000 tonnes of ore. They don't road it 2000 km either. Road about 600km max
Bout 1000 tonne a day. Anyway; got to get back to my sums. Currently calculating for moving 10 million tonnes in 3 months.
