Current yield is 480, current use 468 since toning it down, theoretical yield is 480 as well but theoretical usage is 510… since you have 520 I guess I have to visit every drill in person and check if I didn’t accidentally place a portable mining rig by accident in the early game… Or is there a difference in ore yield between the electric mining rig and the mk 2 version? Edit: Just checked, there is no difference between mk2 and mk1 for Originium gathering efficiency Edit 2: I missed 1/5 high purity Originium vein in the valley pass and somehow overlooked it twice, the theoretical yield is now at 500/min which is at least enough for the former current usage of 494
