The project involved earthworks utilising 40t and 100t fleets for the construction of the stage 6 upstream embankment raising of Tailings Storage area 1 (TSF1). The site is located 50km northeast of the township of Wiluna in the Northern Goldfields region of Western Australia.
TSF1 is a paddock type storage area, with an approximate storage area of 73 ha. The project works involved bulk earthworks to raise the perimeter embankments, decant accessway and decant structure.
Additional works onsite include removal of unsuitable material and construction of a buttress. IMC constructed the TSF1 lift with Cat 992 Loaders and Cat 777 Dump Trucks supplemented with Cat D9 and D8 Dozers, Cat 14 Graders, Cat 740 water trucks, Cat 50t and 36t Excavator and 20t pad foot rollers..
