Geological specimen - Galena (with quartz), unknown
Galena is the natural compound of lead and classed as a sulphide, it crystallises in a cubic pattern and its chemical formula is PbS. Galena is a primary source of both lead and silver. This specimen of Galena comes from Broken Hill. Broken Hill has one of the world’s largest and most significant deposit of ore for the production of lead. Mining of Galena at Broken Hill began with the staking of land by Charles Rasp in 1883. By the following year, in 1884, Rasp and six others had formed Broken Hill Mining Company. Broken Hill Mining Company eventually evolved into BHP group limited and is currently the largest mining company in the world and the largest company in Australia. There is archaeological evidence from artefacts discovered in Turkey that humans have been extracting lead from galena by the process of smelting since at least 6500 BCE. This specimen also has quartz on the top surface which is frequently discovered alongside Galena. This mineral specimen is of historic significance as a sample of Galena extracted from Broken Hill during the 19th century. Mining for Galena in Broken Hill begin in 1883 by Charles Rasp and evolved into the world’s largest mining company – BHP Group Limited. Broken Hill is one of the world’s most significant deposits of ore for the production of lead. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.A flat, hand-sized, grey sulphide specimen that is the natural compound of lead with a quartz formation on the top surface.

Geological specimen - Azurite, Unknown
Azurite is a secondary copper mineral made by the weathering of copper sulphide ore deposits. Azurite is formed from copper, carbon, oxygen and hydrogen. There are over 45 forms of azurite that are more well-known, however over 100 forms have been found. Azurite is also commonly found together with Malachite, and Azurite is often psuedomorphed to Malachite. This specimen was found at the Great Cobar Copper Mine in New South Wales, which was founded in 1870. At the time it was one of the largest mining operations in the world. It was the largest copper mine in Australia and housed the southern hemisphere’s tallest chimney stack. The international price of copper collapsed at the end of World War 1 which led to the closure of the Great Cobar Mine on March 16th 1919. A year later on March 10th 1920 an underground fire in the CSA (Cornish, Scottish, Australian) mine started and burned for 16 years. The closure of the mine and the fire left thousands jobless and many people left the area. These were factors in Cobar facing a long stretch of poverty, until a boom in the 1960s led to the reopening of the mine. The mine still operates today, obtained by Metals Acquisition Limited in June 2023. Azurite is considered an uncommon mineral. Named for its deep blue colour, azurite was historically used for pigment making and as a gemstone, despite its softness. This specimen was donated to the Burke Museum between 1868-1880 as part of a larger collection of geological and mineral specimens. Many of the specimens in this collection were obtained as part of the Geological Survey of Victoria, which started in 1852. The Survey aimed to map the scientific makeup of the earth.A solid copper mineral with shades of darker blues almost covering it.burke museum, beechworth, indigo shire, beechworth museum, geological, geological specimen, mineralogy, cobar mines, great cobar copper mine, cobar mining, new south wales, azurite, azurite specimen -

Geological specimen - Tourmaline (schorl), Unknown
Tourmaline is a group of minerals belonging to the complex borosilicate mineral class. These minerals are known for their striking and varied colours, making them prized gemstones. Tourmaline crystals can come in various shades, including pink, green, blue, brown, black, and colourless. They are often transparent or translucent. Tourmaline's chemical composition is complex, but it typically includes elements such as aluminium, iron, magnesium, sodium, lithium, and potassium. The specific arrangement of these elements in the crystal lattice gives rise to the different colours and properties of tourmaline specimens. Tourmaline specimens from Beechworth, Victoria, Australia, are a notable part of the region's mineral heritage. These tourmalines are of interest to mineral collectors and enthusiasts. While the tourmaline found in Beechworth is not as well-known as some other tourmaline varieties, it has unique characteristics and a historical context associated with the gold mining areas in Beechworth.The significance of tourmaline in Beechworth, Victoria, Australia, lies in its unique geological and historical context, contributing to both scientific and cultural aspects. The tourmaline mined in Beechworth is a rare and unique variety of tourmaline that is primarily found in the historic gold mining areas surrounding Beechworth. Its occurrence is closely linked to the geological processes that shaped the region during the Gold Rush era. The discovery of tourmaline in Beechworth adds to the rich mineral heritage of the area, which was historically known for gold mining. The specimens serve as a tangible connection to the region's mining history and contribute to preserving its geological legacy. The presence of tourmaline in Beechworth showcases the mineralogical diversity of the area.

Geological specimen - Garnet crystals in galena, Unknown
Majority of Galena in Australia is found in hydrothermal deposits emplaced around 1680 million years ago which have been heavily metamorphosed. Galena is the natural mineral form of lead sulfaide. It occurs generally as fine to large crystals due to syntectonic remobilization at low temperatures and moves to a suitable location. The colour is a shining lead and silvery gray with high specific gravity between 7.2 and 7.6 gms/cm3 and contains 86.6 lead sulfaide in its purest form. Its cyrstal system is cubic with perfect cleavages, and contract penetration and lamellar twinning. This particular specimen is from the Broken Hill mine, it is one of the largest lead mines located in Western New South Wales and still has ore reserves amounting to 20.9 million tonnes of ore grading of 7.4% lead, 9.4% zinc, and 61.5 million oz of Silver. Throughout its history, it has produced over 200 million tonnes of ore throughout its 127 years of mining history dating back to 1885. Galena mineral ore found in Australia is considered rare, as it is only currently found in the Broken Hill Mine of Western New South Wales. It represents heritage value through the systematic collecting of the geological surveyers in Victoria and Australia during the early to late 19th Century. The fact that it is only found in one mining area of Australia, shows that this specimen is rare for examples of Australian Galena. This mineral specimen is one part to a larger collection, aquistion, and distribution of Garnet in Galena around Australia and parts of the world and donated to the Burke Museum between 1860-1880. While this specimen was not found by the Victorian Geological Survey, it shows the historical need for mapping geological areas around the Gold Rush region to further identify areas of precious metal and gem aquisition. Additionally, collecting these specimens was an important part of mapping the scientific make up of the earth's surface. Many were sent to institutions for further contribution to research and scientific knowledge of the specimens.

Geological specimen - Pyrite crystals in black slate, Unknown
Pyrite also known as iron Pyrite or fools gold is an iron sulfide with a chemical formula of FeS2 and is the most abundant sulfide mineral. Its metallic luster and pale brass-yellow hue give it a superficial resemblance to gold for which its nickname of Fools Gold comes from. There are a number of iron pyrite mines in Victoria and many would have been mined during Victoria's Gold Rush revolution in the 19th century. As it's lustrius yellow metallic look closely resembles gold, it is likely that it was often mistaken for gold as real gold was also often found in similar metamorphic and sedimentary rock. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these collections were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush). Collecting these specimens was an important part of Australia's early Geoplogical scientific discovery for mapping the earth's surface. It is unknown where in Victoria this specimen was mined from however; it shows strong provenance connections to Victoria's gold mining history and represents through larger economic and cultural structures the impact the Gold Rush had on Victoria during the 19th century.
