Since then people have come to Australia from all over the world to try their luck and the opal mining boom took off. But its been a tale of highs and lows. In the 1930s and 40s the Great Depression almost led to Coober Pedys total collapse, and the town was only saved in 1947 when an Aboriginal woman made a recordbreaking find which made headlines and sparked a new opal rush.
Mining. Although large copper deposits are mined by opencut methods in many of the major producing countries, most of the copper ore produced in Australia comes from underground mines. The traditional method used at most mines involves the ore being broken and brought to the surface for crushing.

It is Australias largest mine in terms of scale, with its pits covering more than five square kilometres and descending to a maximum depth of 700m. The mines owners have also invested considerably in community projects in the KalgoorlieBoulder community, contributing over A1m each to a number of initiatives, such as the Goldfields Arts Centre, Goldfields Oasis Sports Centre and Ray Finlayson

Copper is widely distributed in Australian rocks of Precambrian and Paleozoic age (more than 250 million years old). Most copper is mined or extracted as copper sulphides from large openpit mines in porphyry copper deposits, but it is also found within many other types of deposits, including ironoxidecoppergold orebodies and sedimenthosted copper deposits.

Copper is the leading commodity produced in South Australia with vast resources: South Australia hosts 68% of Australias economic demonstrated resources of copper (GA, 2015) South Australia produces around a quarter of Australias mined copper production (262 569 t (DSD, 2014) of 995 921 t (BREE 2013). Copper is the commodity most explored for within South Australia.
The history of opal mining in Australia is one of danger, regeneration, and success against great odds. As far back as 4,000 BCE, humans have treasured opals and mined them in various locations, such as Kenya and Hungary. However, due to an unlikely combination of geology, fortuitous finds, and the two world wars, Australia has become the worlds primary source of opal since the 1880s.
