I have done some calcs for you Kalenn, If we have 50kt pa of copper production we should need to move approx. 166.6kt of concentrate.

The max payload of a 20ft shipping container is 21.6t. That means we can fill them with 12m3 of concentrate. We are going to move 7716 20 ft shipping containers of copper concentrate.

For AN there will be 1852 shipping containers per a year at 12kt of production. Approx 40kt of copper concentrate.
