Today,repparttar Queensland opal fields cover an area inrepparttar 145289 southwest portion ofrepparttar 145290 state, approximately 1000 kilometres long by 300 kilometres wide.

Coober Pedy, South Australia

The Coober Pedy opal fields were discovered in 1915. Producing white or milky opals, until recently, Coober Pedy wasrepparttar 145291 main producer of precious opal. Todayrepparttar 145292 opal fields encompass an area of approximately 45 kilometres.

The name “Coober Pedy” is derived formrepparttar 145293 Aboriginal word “kupa piti” which loosely translated means “white Man in a Hole.” An isolated and rugged location, Coober Pedy is frequented by freezing cold nights, days whererepparttar 145294 temperature soars above 40° C and is inundated by millions of bush flies. Too hot to live above ground, homes in Coober Pedy are made in underground burrows.

Mintabie, South Australia

The Aboriginals wererepparttar 145295 first to sell black opal from Mintabie at Coober Pedy after WW1 but keptrepparttar 145296 place secret for some time until eager miners discoveredrepparttar 145297 opal field inrepparttar 145298 1930’s. As a result ofrepparttar 145299 remoteness ofrepparttar 145300 area and lack of water, mining inrepparttar 145301 area was on a small scale.

Mining production greatly increased beginning in 1976 as heavy earth-moving equipment was brought in. The opal, sandwiched between layers of sandstone and rock below ground, are drilled or blasted through with explosives.

The Mintabie area is now producing very attractive, semi-black opal.

Andamooka, South Australia

Discovered in 1930, Andamooka is one of Australia’s most famous fields. Located 600 kilometres north of Adelaide but southwest of Coober Pedy in harsh desert country, Andamooka is derived from an Aboriginal name meaning “Large Waterhole.” It isrepparttar 145302 only town in Australia whererepparttar 145303 streets have no names.
