List Of Queensland Opal Mining Fields

Obrada...

The Queensland opal fields are vast and cover thousands of kilometers from the West to the South West of the state. If you look at the map above, you can see where the fields are spread across a 1000km stretch of area between Winton and Yowah. This area is known as the Winton Formation and is made up of weathered sedimentary rock from the Cretaceous period.

The Queensland opal fields are considered to be the most remote and difficult to work in mines. The area is dry, hot and covered in red dirt which gets into everything. Lucky for us these Queensland opal fields are producing some of the most beautiful boulder opal we have ever seen.

Queensland opal is increasing in popularity with it’s unique colors and patterns. The Yowah opal has become very popular, particularly in the USA where designers have been using unique Queensland opal to create amazing pieces of jewelry.

Some of the famous Queensland opal fields are:

Koroit opal field
Yowah opal field including Black Gate
Quilpie opal field including Hayricks, Bull Creek, Pinkilla
Opalton opal field to Horse Creek
Kynuna opal field
Yaraka opal fields to Mount Tighe
Juhdah opal fields and Opalville mines
Bulgroo opal fields
Kyabra-Eromanga field
Toompine opal fields includes Lushingtons, Coparella, Duck Creek, Sheep Station Creek and Emu Creek

KOROIT OPAL FIELDS

Koroit is situated on the Humeburn road 100 kilometres north-west of Cunnamulla. Opal was first discovered there in 1897 by Lawrence Rostron, the manager of Tilboroo station, Eulo. The Koroit field has been relatively quiet in comparison to other Queensland opal fields. In 1972, a small number of men moved onto the field, among them Mike Bennent who was still there in 1997. Like most Queensland opal fields mining is carried out above ground using excavators and bulldozers.

YOWAH OPAL FIELDS

The earliest records on mining in Yowah date back to the 1880s for this remarkable little field. It is one of the oldest producing opal fields in Australia with the original mining leases and claim still worked over today. Like most Queensland opal fields it is a difficult environment compounded by the fact that permanent water is scarce. In the past miners could work the fields only after it rained, luckily today miners use artesian bores (underground water well) as a supply.

Yowah is most famous for the Yowah Nut and Queensland boulder opal. These “Yowah nuts” are ironstone rocks resembling nuts which when opened up have precious opal in the center. These nuts are quite small ranging from 5mm to 200mm. This is fast becoming one of the most popular types of Queensland opal available on the market today. The mines are very popular with fossickers as the mine is easily accessed from the main road.

JUNDAH OPAL FIELDS

The Jundah mines are unique in that they produce not just one but nearly all the types of different opals found in Australia including black, crystal and boulder opals. There are basically only two main fields. The Old Field, known as the Top Flat and the famous Black Mine which joined it half a kilometer to the east. Opal from these two areas was of the highest quality.

The Black Mine of Jundah was Australia’s first black opal mine, mined 10 years before black opal was discovered in Lightning Ridge.

WINTON OPAL FIELDS

Winton is one of the oldest and most well known Queensland opal fields. It has a depp history reaching back to 1885 when Banjo Paterson wrote Waltzing Matilda at one of the stations outside of Winton.

Today it is a beautiful town with a real buzz about opals. Most tours from this area will take you out to opalton, once of the other Queensland opal fields that was established at the same time as Winton. Winton boulder opal is some of the brightest and most beautiful gem quality boulder opal available on the market. It is extremely stable and the hard sand stone makes it perfect for use in everyday jewelry.

Interesting to read about old opal mines in Queensland that still might have some opal if you want to do fossicking.

Volcanic opals in Queensland were found in Springsure in 1872 and known as Mountain opal.

A Mountain opal sold in London in 1896 for 150 English Pounds.

Opals were also sold in London from this mine in 1879 and 1886

The Lease to crown was 18 pounds per year, but the opals were not very stable and hard to find in the rock cavities

At the time this deposit was compared to the Hungarian and Mexican mines, as no one had seen volcanic opal from Australia in those early days.

The Queensland government report also mention opals found Honduras were similar and one small deposit in Rocky bridge Creek in new south wales was also volcanic

Yowah Opal Stones

Polja opala Queenslanda su ogromna i prostiru se tisućama kilometara od zapada do jugozapada države. Ako pogledate gornju kartu, možete vidjeti gdje se polja prostiru na 1000 km dugom području između Wintona i Yowaha. Ovo područje poznato je kao Winton formacija i sastoji se od istrošenih sedimentnih stijena iz razdoblja krede.

Polja opala Queenslanda smatraju se najudaljenijim i najtežim za rad u rudnicima. Područje je suho, vruće i prekriveno crvenom prljavštinom koja ulazi u sve. Srećom po nas, ova polja opala u Queenslandu proizvode neke od najljepših kamenih opala koje smo ikada vidjeli.

Queensland opal postaje sve popularniji zbog svojih jedinstvenih boja i uzoraka. Yowah opal je postao vrlo popularan, posebno u SAD-u gdje su dizajneri koristili jedinstveni Queensland opal za stvaranje nevjerojatnih komada nakita.

Neka od poznatih polja opala Queenslanda su:

Koroit opalno polje
Polje opala Yowah uključujući Black Gate
Polje opala Quilpie uključujući Hayricks, Bull Creek, Pinkilla
Polje opala Opalton do Horse Creeka
Polje opala Kynuna
Yaraka opala do planine Tighe
Polja opala Juhdah i rudnici Opalville
Bulgroo opalna polja
polje Kyabra-Eromanga
Opalna polja Toompine uključuju Lushingtons, Coparella, Duck Creek, Sheep Station Creek i Emu Creek

KOROIT OPALA POLJA

Koroit se nalazi na cesti Humeburn 100 kilometara sjeverozapadno od Cunnamulle. Opal je ondje prvi put otkrio 1897. Lawrence Rostron, upravitelj stanice Tilboroo, Eulo. Polje Koroit bilo je relativno mirno u usporedbi s drugim poljima opala u Queenslandu. Godine 1972. mali broj muškaraca preselio se na polje, među njima i Mike Bennent koji je još uvijek bio tamo 1997. Kao i većina polja opala u Queenslandu, rudarenje se izvodi iznad zemlje pomoću bagera i buldožera.

YOWAH OPALA POLJA

Najraniji zapisi o rudarenju u Yowah datiraju iz 1880-ih za ovo izvanredno malo polje. To je jedno od najstarijih polja za proizvodnju opala u Australiji s izvornim zakupom rudarstva i potraživanjem koje se i danas obrađuje. Kao i većina polja opala u Queenslandu, ovo je teško okruženje komplicirano činjenicom da je trajna voda rijetka. Nekada su rudari mogli obrađivati polja samo nakon kiše, a danas srećom rudari koriste arteške bušotine (bunare podzemne vode) kao opskrbu.

Yowah je najpoznatiji po Yowah Nutu i Queenslandskom opalu . Ovi "Yowah orasi" su kamene stijene koje podsjećaju na orahe koje kada se otvore imaju dragocjeni opal u sredini. Ove matice su prilično male u rasponu od 5 mm do 200 mm. Ovo brzo postaje jedna od najpopularnijih vrsta Queenslandskog opala dostupnih na današnjem tržištu. Rudnici su vrlo popularni među fosičarima jer se rudniku lako pristupa s glavne ceste.

POLJA JUNDAHOVA OPALA

Rudnici Jundah jedinstveni su po tome što proizvode ne samo jedan, već gotovo sve vrste različitih opala pronađenih u Australiji, uključujući crne, kristalne i kamene opale. U osnovi postoje samo dva glavna polja. Staro polje, poznato kao Top Flat i poznati Crni rudnik koji mu se pridružuje pola kilometra istočno. Opal iz ova dva područja bio je najviše kvalitete.

Crni rudnik Jundah bio je prvi rudnik crnog opala u Australiji, iskopan 10 godina prije nego što je crni opal otkriven u Lightning Ridgeu.

WINTONOVA OPALA POLJA

Winton je jedno od najstarijih i najpoznatijih nalazišta opala u Queenslandu. Ima Deppovu povijest koja seže do 1885. kada je Banjo Paterson napisao Waltzing Matilda na jednoj od stanica izvan Wintona.

Danas je to prekrasan gradić u kojem se o opalima stvarno priča. Većina tura iz ovog područja odvest će vas do opaltona, jednog od ostalih polja opala u Queenslandu koje je osnovano u isto vrijeme kad i Winton. Winton boulder opal jedan je od najsjajnijih i najljepših kamenih opala kvalitete dragulja dostupnih na tržištu. Izuzetno je stabilan, a tvrdi pješčani kamen čini ga savršenim za upotrebu u svakodnevnom nakitu.

Zanimljivo je čitati o starim rudnicima opala u Queenslandu koji još uvijek mogu imati nešto opala ako želite fosirati.

Vulkanski opali u Queenslandu pronađeni su u Springsureu 1872. i poznati su kao planinski opal.

Planinski opal prodan u Londonu 1896. za 150 engleskih funti.

Opali su se također prodavali u Londonu iz ovog rudnika 1879. i 1886. godine

Zakup krune bio je 18 funti godišnje, ali opali nisu bili baš stabilni i teško ih je pronaći u šupljinama stijena

U to su vrijeme ovo nalazište uspoređivali s mađarskim i meksičkim rudnicima, jer nitko nije vidio vulkanski opal iz Australije u tim ranim danima.

Izvješće vlade Queenslanda također spominje da su opali pronađeni u Hondurasu slični i da je jedno malo ležište u Rocky bridge Creeku u novom južnom Walesu također bilo vulkansko
