Oz Mineral's Prominent Hill mine is located 650 kilometres north-west of Adelaide and will produce ore concentrate with copper, gold and silver. The project costing in excess of $1 Billion will include development of an open-pit mine, a conventional grinding and flotation processing plant with an 8mtpa capacity, construction of a permanent village to accommodate a steady-state workforce of approximately 500 and construction
of a haulage road, power line and bore field.

York Civil undertook the construction of the footings and associated civil works for the transmission towers for the 150-kilometre power line between Olympic Dam
and Prominent Hill.
