What You'll Learn
Mineral Hill field, Condobolin district, New South Wales
Malachite is a mineral that can be found in Australia, specifically in the Mineral Hill field in the Condobolin district of New South Wales. The Mineral Hill mineral field, also known as Mineral Hill Mine, is located in the northern part of the Lachlan Fold Belt in central-western NSW, about 65km north of Condobolin, in the parish of Talingaboolba.
The Mineral Hill field is known for its varied copper, gold, lead, zinc, and silver sulphide deposits. It was once a productive gold and copper mine but has since been placed into care and maintenance. The mine operated as an open-pit mine, and its history dates back to at least the 1990s.
The presence of malachite in the area is associated with the mineralization of base metals, particularly copper. Malachite is a copper hydroxy-carbonate mineral known for its lustrous, silky, and velvety texture. It often forms radiating fibrous crystals or sheaths of emerald-green colour, making it a very attractive specimen.
In addition to Mineral Hill field, malachite can also be found in other locations within Australia, such as the Nymagee Mine in central-western New South Wales, and the Peak Downs Copper Mine in Queensland. These locations have yielded significant specimens of malachite, contributing to the mineral diversity of Australia.

Cattle Grid deposit, Oakden Hills, South Australia
The Cattle Grid deposit in Oakden Hills, South Australia, is a significant site for mineral deposits and mining. Located in the Pastoral Unincorporated Area of South Australia, the Cattle Grid deposit has been a source of various minerals, including copper, silver, cobalt, and bismuth.
The site was discovered in 1971, hidden beneath dune sand, and is the largest deposit in the Mt Gunson field. Between 1974 and 1986, the Cattle Grid deposit yielded 7.2 million tonnes of ore, with a copper grade of 1.9% and a silver grade of over 8 grams per tonne, resulting in a total of 137,000 tonnes of contained copper. This made it a valuable mining location, with the site being sporadically re-mined for its valuable mineral resources.
The Cattle Grid deposit is also known for its rare and aesthetically pleasing mineral specimens. One notable example is a copper bismuth sulfide crystal, collected over 30 years ago when the mine was still operational. This specimen, with dimensions of 1.1 cm x 0.9 cm x 0.3 cm, stands out for its sharp thumbnail crystal structure, lustrous surface, and hints of iridescence. It is considered one of the finest examples of its kind in the world.
Additionally, the Cattle Grid deposit has yielded a rare and superb pseudomorph specimen from the Mount Gunson Mine. This specimen, consisting of malachite pseudomorphs after atacamite prisms, features a contrasting gossan matrix that showcases a lustrous, undamaged cluster of malachite. Collected in 1994, this specimen is a unique representation of the mineral wealth found in the Cattle Grid deposit of Oakden Hills, South Australia.

Central Mine, Broken Hill South Mine, New South Wales
Malachite is a mineral that can be found in various locations across Australia. One of these locations is New South Wales, where it can be found in the Mineral Hill field in the Condobolin district, Kennedy Co. The Nymagee Mine in central-western New South Wales is also known for producing malachite, yielding 24,800 tons of copper from 1880 to 1917.
In the context of New South Wales, it is worth noting that Broken Hill, a city in the far west region of the outback, has a prominent mining history. The city is recognised for its silver-lead-zinc ore deposits, which led to the establishment of various mines. One notable mine in Broken Hill is the Central Mine, which is part of the Broken Hill South Mine (also known as the BHS Mine or South Mine).
The Broken Hill South Mine was established as The Broken Hill South Silver Mining Co Ltd in 1885. This mine covers the central area of the Broken Hill line of lode, with a length of approximately 4 kilometres. Mining operations in this area commenced in 1888, focusing on Blocks 7 and 8 of the line of lode. The South Mine is located adjacent to the Broken Hill Proprietary Mine and took over leases for Blocks 9-16 when BHP left in the 1940s.
The Central Mine, specifically identified as Block 9 (ML 9), is a significant component of the Broken Hill South Mine complex. It is mentioned alongside other sections of the mine, such as the Kintore opencut and the Southern Operations Mine. The Central Mine falls within the Yancowinna County and is an integral part of Broken Hill's mining landscape, contributing to the city's historical significance in Australia's mining industry.

Nymagee Mine, central-western New South Wales
The Nymagee Mine, located in central-western New South Wales, is known for its extensive copper deposits. From 1880 to 1917, the mine produced a significant amount of copper, with a total output of 24,800 tons. This historical mine has not only contributed to the region's mineral wealth but also offered insights into the geological characteristics of the area.
The Nymagee Mine is part of the Hera-Nymagee project, which involves the development of both the Nymagee copper deposit and the Hera gold base metal deposit. The project is located approximately 100 kilometres southeast of Cobar in central New South Wales. The Nymagee deposit is characterised by massive sulphide mineralisation, while the Hera deposit, which began production in September 2014, contains high-grade copper sulphide mineralisation as well.
The Hera-Nymagee mine was developed in two stages. The first stage focused on establishing an underground mine and a processing plant at the Hera deposit, which produces gold and silver doré bars and lead-zinc concentrate. The second stage involved integrating the Nymagee copper deposit, utilising the infrastructure from the first stage. The infrastructure at the mine includes a diesel-generator power station, a tailings storage facility, and an accommodation village for workers.
Malachite, a copper hydroxy-carbonate mineral, has been found in various locations across Australia, including New South Wales. Malachite is known for its lustrous, silky, and emerald-green appearance, resembling plush velvet. While the mention of the Nymagee Mine in relation to malachite is scarce, the mine's copper production aligns with malachite's association with copper deposits.

Peak Downs Copper Mine, Queensland
Malachite is a mineral that can be found in Australia, specifically in the state of Queensland at the Peak Downs Copper Mine. The Peak Downs Copper Mine is an open-pit mine located in Queensland's Bowen Basin, 31 kilometres south-southeast of Moranbah. The mine began operations in 1972 and has been a significant source of coal, specifically high-quality hard coking coal, for the region. Queensland is known for its rich deposits of hard coking coal, which is highly valued due to its use in steelmaking.
The Peak Downs mine is owned by BHP Mitsubishi Alliance, Australia's largest coal miner and exporter. By 2022, the mine was producing an impressive 37 million tonnes of coal annually. The coal is extracted using the open-cut, or surface, method, where coal is extracted just below the earth's surface with specialised equipment. This method involves removing the overburden, or the layers of soil and rock above the coal, using draglines, which are large mobile bucket excavators.
In addition to its coal production, the Peak Downs mine has also yielded malachite, a mineral that forms in the oxidised zone of a copper orebody. Malachite is a copper hydroxy-carbonate mineral known for its lustrous, silky, and velvety texture. It has a stunning emerald-green colour that can glow in direct sunlight due to light conduction along its crystal fibres. The Australian Museum holds a notable specimen of malachite from the Peak Downs Copper Mine, measuring 20 x 45 x 20 centimetres. This specimen was extracted from an open cavity in the mine's Albert Shaft at a depth of 66 feet (20 metres) in June 1865.
The Peak Downs Copper Mine has contributed significantly to our understanding of minerals and the region's geological history. The malachite specimen in the Australian Museum, for example, was donated by the Peak Downs Copper Mining Company in August 1865 and has provided valuable insights into the mineral's characteristics and formation. The mine's ongoing operations continue to shape our knowledge of Earth's mineral resources and their applications.
