Australian Opal Mining Fields

Opal is found around the world (Brazil, Mexico, Honduras and the western US), however, Australia produces 95% of the world's precious opal and it is the official national gemstone. The important opal mining areas are in New South Wales, South Australia and Queensland (around the edges of the Great Artesian Basin).

 

==============================================================

White Cliffs

White Cliffs is Australia's oldest commercial opal field in New South Wales, found in the late 1880's. The found of opal there excited the world and the town soon developed, by the 1920's it had a population of more than 3,000 (2008). Formerly White Cliffs was a large producer of high-quality opal, however, the main run was worked out by 1930 and the field all but died out.

Lighting Ridge

This field was discovered in 1905 by kangaroo shooters (2008). Lightning Ridge is one of the few places in the world where the precious and highly prized black opal is found. Though the there is a recent decline in production it is still the largest producer of opal by value. The township and the lure of the black opal have been encapsulated in Laurie Hudson's poem:

Queensland fields

Australian opal was first mined commercially at Listowel Downs in Queensland in 1875. The fields are spread across 1,000km and produce almost all the world 's supply of boulder opal. Boulder opals (opals in concretionary ironstone) are mined in Queensland from numerous localities in a zone extending from the Eulo and Cunnamulla district in the south and northwest for over 700 km to Kynuna in the north. The towns of Quilpie, Yowah and Winton are the main opal mining and wholesale centers. 

Andamooka

Andamooka is in the harsh desert and located near the edge of Lake Eyre. It was discovered in 1935 and is famous for producing brilliant crystal seam opal. The producing reached its peak in the 1960's, however, unfortunately, this field is worked out with very little commercial production since the 1970's. Today much of Andamooka's population is employed at the nearby uranium mines of Roxby Downs.

Coober Pedy

The bulk of the Worlds' light seam opal was mined at Coober Pedy. Mining extended over an area 50 kilometres long, running approximately north south. During the 1960s, the mining industry expanded rapidly as many European migrants came to seek their fortunes. Opal mining developed into a multi-million-dollar industry at that time and Coober Pedy became a modern mining town. In 2002 Coober Pedy's production has fallen to 25% of its heyday.
