 2 identicalprimary and secondary crushing stations in a stagedarrangement. The coarsely crushed ore will then be conveyedto the mine stockyard. The ore will be reclaimed from thestockpiles and conveyed to the train load-out facility for loadinginto trains which transport materials to the port facility where itwill be likely shipped by bulk carrier to several ports including inChina. Other major facilities that will support the operationsinclude power generation, explosives facilities, fuel andlubricants facilities, administration buildings, workshops and apermanent village.Power sourceCurrent designs contemplate that power for the mine site andother areas will be supplied by a hybrid power plant consistingof diesel generators and a regenerative battery power solution.Further, there is a plan to connect the facility to the power gridlocal operator Électricité de Guinée. This will require anapproximately 20km connection line to the main grid once it isavailable and would substantially reduce energy costs andfuel consumption. |
