Geology for mining at Coober Pedy

The story of Coober Pedy is intimately tied with geology. Some of the most fantastic episodes of human action and reaction that I have witnessed have come about simply because of the way that nature deposited opal in Coober Pedy. Furthermore, the great mystery of opal deposition and formation is illustrated in its purest form in Coober Pedy. It is there for all to see. Illterate miners from all parts of the globe recognised it, lived by it, dreamed about it, fought over it, and gloried in it, but technical authorities, geologists and scientists, let it pass unnoticed. How strange this is, how incredible but true - an to think of all the money that might have been mine if I had this knowledge six years ago or applied it later with more intelligence.

Opals from Down Under

Did you know that the vast majority of the world's opals are mined in Australia? According to the Minerals Council of Australia, opals from down under were discovered in 1915 by a 14-year-old boy who was with a group of gold prospectors at the edge of the Great Victoria Desert northwest of Adelaide. The Australian 'opal rush' was on, and Australian opals have enchanted the world ever since.

Australia produces about 95 percent of the world's supply of mined opals. Though other countries produce opals, few opal deposits compare to those found down under. Australian opal mines produce precious opals in a rainbow of colors. Opals from down under are simply spectacular with the most prized Australian opals coming from minefields located in South Australia such as Lightning Ridge which is know for its black opals.
