Short climb up a dune.
From its humble origin of discovery by a lone drilling rig, near a livestock watering dam on the Roxby Downs sheep station in 1975, the Olympic Dam operation has developed into a mining and processing operation of world class. The giant orebody was concealed under 350 metres of barren sedimentary rocks in an isolated, arid region of northern South Australia, covered on the surface by up to 30 metres of sand. The composition of mineralisation is remarkable.
While the geological team which discovered the orebody was looking for and found copper, they also uncovered a veritable treasure trove of minerals not previously found together in such large concentrations anywhere else in the world. Apart from containing the sixth largest known copper deposit in the world, Olympic Dam (some 560km north-west of Adelaide) is by far the world's single largest known uranium orebody, the tenth largest gold reserve and one of the largest known silver deposits.
