Makes you wonder if the shipping port lets piles of Iron Ore sit at no charge....betcha this has already been worked out. Its called Logistics. Mine enough Iron Ore to fill a couple of ships. Make sure you have a buyer and product is paid for(money in escrow). Make sure port has space and location to accomodate the Iron Ore. Order the ship. The Clock starts. Take more than enough to fill one ship to port. Continue the mining and order another ship for next load. And it goes on and on til the or is gone.
