40 semi trucks, each hauling 3 loads a day from mi

40 semi trucks, each hauling 3 loads a day from mine to dock would be 4800 tons/day. Or 30 trucks hauling 4 loads a day if that is your preference. Either way, in 15 working days, and we could have enough ore on the dock to load another Panamax.. Cut that to 11-12 days if the trucks keep bringing in ore while the present ship is being loaded.. That would put some brown concrete in shorty's britches if another Panamax showed up in 2 weeks!!!  LOL!

 If they are really smart, the trucking firm could start half the trucks from the dock locality, and half from the mine in the morning, to keep a constant steady flow and minimize congestion at the Customs gates.. but hopefully they figured that out already..
