a much better place is the dwarven mine, theres 3 iron right next to eachother with a resource dung with a deposit box right next to the door, so you just hop in deposit hop out. After you get better at it it literally takes 2-3 seconds max to bank ores, the best place to get to this area is in ne falador next to party room. You will see the 3 rocks right next to resource dung to the north.
