Australia is known for its opal and diamond treasures, but it also has abundant mining fields where sapphires and emeralds can be found. Australian emeralds are typically found in limited quantities and are not as well-known as Colombian emeralds. However, they still hold significance in the gemstone industry and are prized for their unique qualities and charm. The New England area of New South Wales has produced most of the country's gem-quality emeralds, with the largest deposit found near Emmaville. Emeralds have also been commercially mined in Western Australia at three deposits: Poona, Menzies, and the Curlew Emerald Mine in the Shire of East Pilbara.

What You'll Learn
The Curlew Emerald Mine in East Pilbara's Shaw River District
The Curlew Emerald Mine is located in the Shaw River District of East Pilbara, Western Australia. The mine is approximately 90 kilometres west of Marble Bar and 5 kilometres north of the Woodstock-Marble Bar Road, just east of the Mt Webber iron ore turn-off. The mine was established in 1976, and it is known for its small deposit of Australian emeralds, which are renowned for their classic emerald greens with a medium to medium-light saturation and attractive translucent to semi-transparent opacity.
The history of the Curlew Emerald Mine before 1976 is not well documented. However, it is believed that the emerald deposit was discovered in the 1920s. Active mining at the site took place between 1976 and 1981, with an annual production of approximately 4.5 kilograms of facetable emeralds and 40 kilograms of non-facetable material. Each year, an average of 20 'king' stones were also recovered, ranging from 15 to 20 carats in size. All the emeralds extracted during this period were sold to an Indian dealer for the jewellery trade.
The Curlew Emerald Mine is one of the four main commercial deposits of Australian emeralds, with the other three being Emmaville in New South Wales, and Poona and Menzies in Western Australia. Australian emeralds are typically associated with granite pegmatites and metamorphosed rocks called schists. They are also occasionally found with altered limestones or embedded in calcite or quartz. The New England area of New South Wales has yielded most of Australia's gem-quality emeralds.
Emeralds from the Curlew Mine are incredibly scarce and not readily available in the jewellery marketplace. They are known for their colour purity, transparency, clarity, and brightness. The mine has been the subject of photography, with photographers such as Sue Koepke, Kim Macdonald, and David Sheumack capturing its essence through their lenses.

Emmaville in New South Wales
Emmaville, New South Wales, is located 649 km north of Sydney and sits 872 m above sea level. The town was established in 1839 and was originally known as Vegetable Creek, named after the creek where a piano tuner, Thomas Carlean, discovered stream tin in 1872. The name was officially changed in 1882 to honour Emma Maria Greville, the wife of Lord Augustus Loftus, who was the Governor of New South Wales at the time.
The area around Emmaville is known for its rich mineral deposits, including sapphire, garnet, topaz, arsenic, beryl, quartz, and fossils. The town is home to the Emmaville Mining Museum, which showcases the region's mineralogical heritage and is considered one of the finest attractions in the country. The museum started with a collection of minerals bequeathed to the local community by Mr and Mrs Jack Curnow.
Emmaville is one of the four main commercial deposits of emeralds in Australia. The New England area of New South Wales, where Emmaville is located, has produced most of Australia's gem-quality beryl, emerald, and aquamarine. The largest deposit of these gemstones in the region is found in the Emmaville area. In the early 1900s, over 53,000 carats (10 kg) of beryl and emeralds were produced in this area over 20 years.
The emeralds in Emmaville are usually found in rocks among layers of other minerals such as mica. Open-pit mining or terrace mining are the most common methods used to extract these gemstones. Miners dig pits using shovels, excavators, or other earth-moving equipment. If the emerald-bearing ore is located deep underground, explosives or high-pressure water may be used to remove the soil and rock covering it.

Poona in Western Australia
Australian emeralds are known for their classic emerald greens, with a desirable medium to medium-light saturation and tone, and an attractive translucent to semi-transparent opacity. They are typically associated with granite pegmatites and metamorphic rocks called schists.
The Poona emerald mining area has been the subject of academic research, with studies published in 2016 examining the pressure-temperature-fluid constraints for the emerald deposits in the region. The studies specifically looked at fluid inclusion and stable isotope compositions to understand the geological processes that formed these emerald deposits.
Poona is also home to the Aga Khan Mine, the Emerald Pool mine (also known as the Emerald Gem mine or East Poona mine), and the Fluorite prospect. The region has a rich mining history and has contributed significantly to Australia's gemstone and geological heritage.
It is important to note that while Poona in Western Australia is known for its emerald deposits, there is also a coastal town named Poona in the Fraser Coast Region of Queensland, Australia. This town had a population of 576 people as of the 2021 census.

Menzies in Western Australia
Emeralds are one of the most valuable gemstones in the world, prized for their rare and beautiful green colour. In Western Australia, emeralds have been commercially mined at four main deposits: Poona, Menzies, Pilbara, and Emmaville in New South Wales.
Emeralds are a variety of the mineral beryl, specifically beryllium aluminium silicate. They are typically found in granite pegmatites, metamorphosed rocks called schists, and occasionally with altered limestones, or embedded in calcite or quartz. In Western Australia, emeralds are associated with metamorphic rocks (mica schist) and pegmatite.
The Emerald Gold Mine in Morley's Find, Riverina Station, Menzies Shire, Western Australia, dates back to the late 1930s. The mine was owned and operated by Ernest Robert Bassett, George Widdis McKernan, and William Robinson. The mine had several shafts and was active from the late 1930s to the early 1950s. It is located 15 kilometres north of Morley's Find and 4 kilometres west of the Riverina-Lake Ballard Road.
The Curlew Emerald Mine, established in 1976, is another source of Australian emeralds. It is a small deposit located in a remote area of East Pilbara's Shaw River District. This mine's pegmatites are composed of Quartz-Albite with emerald, Scheelite, Molybdenite, and fine-grained purple Fluorite.

New England region of New South Wales
The New England region of New South Wales is a geographical area in the north of the state, about 60 km inland from the Tasman Sea. The region is known for its diverse mineral deposits, ranging from large coal deposits in the Werris Creek to Boggabri area, to metallics and gemstones on the tablelands.
The New England area has produced most of Australia's gem-quality beryl, emerald, and aquamarine. The largest deposit can be found in the Emmaville area, with smaller deposits near Inverell, Dundee, and Glen Innes. In the early 1900s, over 53,000 carats (10 kg) of beryl and emerald were produced in this area over a 20-year period. An attempt at commercial mining was made at Torrington in the early 1990s, but this was unsuccessful due to low gem quantities.
The New England region is traversed by five major highways and a network of minor roads. The New England Highway is a major route linking New South Wales and Queensland, passing through several towns in the region, including Tamworth, Uralla, Armidale, Guyra, Glen Innes, and Tenterfield. The area is also accessible via the Newell Highway, Thunderbolts Way, Oxley Highway, Gwydir Highway, Waterfall Way, and Bruxner Highway.
The region has a rich Indigenous history, with the Kamilaroi people occupying the area for tens of thousands of years. The original languages, now extinct, included Anaiwan to the south of Guyra and Ngarbal to the north. The population at the time of colonisation was estimated to be between 1,100 and 1,200 in the tablelands, which was relatively low compared to other regions in New South Wales.
