Since 2009 the company has hauled iron oxide / copper / gold ore mined at Prominent Hill from a 1.5 km (0.9 mi) siding at Wirrida, 95 km (60 mi) west of the mine and 129 km (80 mi) from Northgate. In 2012 a new iron ore mine was opened at Peculiar Knob, 22 km (14 mi) from Prominent Hill; until production ceased in 2015 its product was loaded at Wirrida, at a balloon loop immediately north of the Prominent Hill loading site.
