Burgoyne recalled that the tug Florrie ferried a crew there a week later and pegged out the settlement first known as Hummocky. It was officially founded as Hummock's Hill in 1901 by the Broken Hill Proprietary Company (BHP) as the end of a tramway bringing iron ore from Iron Knob in the Middleback Range to sea. Its first shipment was transported across Spencer Gulf to Port Pirie where it was used in lead smelters as a flux. A jetty was built to transfer the ore and the first shipment was sent in 1903. The early settlement consisted of small cottages and tents clustered around the base of the hill. The Post Office opened in 1901 as Hummock's Hill.
