Smelter Bay Five was a hanger bay for the large mobile ore vats that transported ore around the Imperial factory world of Metalorn. The ore conveyor traveled to this room, carrying the ore to be offloaded to the mobile ore vats. During the Mission to Metalorn, Leia Organa abandoned her tracked blaster rifle on the ore conveyor, causing the Empire's agents to believe she was heading to Smelter Bay Five. In reality she had escaped in a different direction.
