Link below. Not of major significance but interesting nonetheless. Over 1000km from T3 and Ghanzi to Walvis bay. Trucking costs would be around US$100/t of concentrate or around US$300/t of Cu or 14c/lb (assuming 33% con grades).. rail would be less than half the cost of trucking I feel. PS - They did use US17c/lb transport costs in the PFS which seems light on considering this includes shipping from walvis bay to China..

Just like grid power a rail project will make this project just that bit more attractive / profitable. Wouldn’t expect anything to happen near term mind you...
