Goldsworthy Mining developed an iron ore mine approximately 100 kilometres east of Port Hedland in the early 1960s and built the towns of Goldsworthy and later Shay Gap as mine sites. A rail line was then built to Port Hedland, where dredging was undertaken to deepen and widen the port's channel, and a wharf was built opposite the township of Port Hedland on Finucane Island. Shipment of ore began on 27 May 1966, when the "Harvey S. Mudd" sailed from Port Hedland to Japan with 24,900 tonnes of ore.
