Galena Chalcopyrite is the earth's primary ore of lead and is mined from a large number of deposits in many countries. It is also an important source of silver. Galena Chalcopyrite is one of the most abundant and widely distributed sulfide minerals across the world. The mineral is found in igneous and metamorphic rocks in medium- to low-temperature hydrothermal veins. This specific specimen was recovered from the mines in Broken Hill, New South Wales. The mines in Broken Hill were first established after Charles Rasp discovered a large amount of silver-lead-zinc ore-body in the area in 1883. BHP (Broken Hill Proprietary) mining company was then established in 1885 and quickly became the lead in Australia's mining industry after they began excavating and exporting the country's largest amount of lead, silver, and zinc. This feat generated over $100 billion in wealth for the company.Galena Chalcopyrite is signifiant as it represents the catalyst for the rise of Australia's most influential mining companies - BHP. The mineral was one of the first to be mined in the country and after being made into lead, was used for a variety of things such as paint, batteries, ammunition, and plumbing materials before it was known to be harmful to humans. 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.

This specimen is from Broken Hill, NSW. Galena is a natural mineral form of lead sulphide and is often found associated with sphalerite, calcite, and fluorite. Galena is an important lead ore mineral, and, in some regions, it is also an important mineral associated with silver ore. Sphalerite is a sulphide mineral that is the main ore of zinc. Rhodonite is an uncommon mineral once used as an ore of manganese in India, however today the scarcity and fragility of the crystals mean it is primarily used as lapidary materials or mineral specimens. In 1883, Charles Rasp who was a boundary rider at the time, discovered what he thought were deposits of tin but were in fact samples of silver and lead. He and six others went on to set up the first mining company in Broken Hill (BHP). The ore body became the largest and richest of its kind in the world mining ore worth more than 42,000 pounds in its first year. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study. Galena contains lead and silver, Sphalerite contains zinc.

Corbould Hall was named after Ballarat School of Mines alumni WIlliam Corbould. William Corbould was the son of a Ballarat tailor. He attended Ballarat College, and obtained certificates in assaying and metallurgy at the Ballarat School of Mines (SMB) in 1883, studying under the revered Professor Mica Smith. Corbould was not a born student and remembered his first experience at SMB: 'From the Registrar's Office I was led to be introduced to the Professor of Chemistry, one Mica Smith. The initial encounter gave me little encouragement - his large laboratory was filled with hundreds of bottles bearing strange labels with queer symbols on them. My heart sank. At the first opportunity I grabbed my hat and made for the door, but the good professor called me back. I pointed out that I was never any good at school ... so it was no use pretending to be clever enough to understand all those weird symbols! The Professor told me not to worry about that and took me to one of the benches where he found a blowpipe and a charcoal block. Mixing together two powders from bottles on the shelf he transferred a sample to the charcoal and directed the bunsen flame onto it. Soon it began to melt and a white bead appeared in front of my eyes. He then took a test tube and added a little colourless liquid from each of two bottles. A beautiful dark blue colour appeared. My interest was won.' During Corbould's mining career he travelled to Europe twice, and visited most of Australia's main mining fields. Corbould started his career as an assayer at Pinnacle Silver Mine, Silverton, and was then a self-employed assayer at Broken Hill. Corbould became an assayer for the infant BHP mine, and later worked in Kalgoorlie and Coolgardie, including managing Hannan's Reward, the oldest gold mine on the Kalgoorlie gold field. He spent 13 years at the Mount Elliott copper fields as general manager. In 1923, at the age of 57, Corbould went to Mount Isa and reported on options, experimented with new metallurgical processes and floated a company. John Carden of CRA said: 'Corbould was the man who brought Urquhart to Mount Isa. He was the man who made it all possible. He is tremendously important in the Mount Isa story, because he was the first technical man, the first professional man on the scene. He was responsible as I said, for bringing finance to the place, but I think even more importantly he was the first man to recognise the need to put all the little claims in the Mount Isa discovery together. I think perhaps his major contribution to Mount Isa was this amalgamation on the various claims. He recognised that the ore bodies at Mount Isa were not as rich as Broken Hill and they would never have survived had it been fragmented, so he was terribly important.' After completing major financial negotiations for Mt Isa Mine from London in 1927 Corbould remained in Europe where he remained until his death. Corbould was awarded the Legion of Honour of the American Institute of Mining and Metallurigical Engineers for fifty years service. Corbould died at Monaco in 1949 at the age of 82. He bequested 6000 pounds to the Ballarat School of Mines, his will stating 'for the purpose of founding a scholarship to commemorate the memory of the late Alfred Mica Smith'. The accumulated income from this sum provides the Mica Smith travelling scholarship, enabling successful students in mining, metallurgy or chemistry to undertake a year's travelling abroad. The first award was made in 1957. In the same year a general purpose hall at SMB was named the Corbould Hall as a tribute to a distinguished former student and generous benefactor.ballarat school of mines corbould building, corbould hall, corbould building

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.

Bradford Kendall was established in 1922 by Lesley Bradford and Jim Kendall, investing their winnings on a race horse. They both previously worked at the BHP Steel Works. They gained contracts with the railways and mining industry. During World War II they also manufactured armaments. During the boom of the 1950s they established several foundries in South Australia, Western Australia, Queensland and Victoria. Bradford Kendall Ltd Wodonga foundry was established in 1954. It melted down old railway wheels, rails and redundant machinery to produce a range of low-alloy steel products, especially for earth-moving vehicles, railways, oil rigs and sugar factories. Wodonga was ideally placed as a change point between the different rail gauges of Victoria and New South Wales, close to the Hume Highway and the Snowy Mountain Scheme. The first sod for the site was turned on 2nd June 1954 and the first melt and pour of molten metal at Wodonga took place on 7th July 1954. Bradford Kendall Plant No.5 in Wodonga became one of the most profitable foundries in the Bradford Kendall group. Bill Black became the first plant Manager, a position he held for 30 years. Another long term employee was Pat Gooding who began work at a 15 year old and retired for the position of Bradken foundry Manufacturing Manager 51 years later. In the early 1980s, Australian National Industries Ltd bought Bradford Kendall and other heavy engineering companies. The Wodonga foundry with its (then) 170 or so staff became part of Bradken Consolidated along with nine other foundries in Australia and New Zealand. In 1989, Kerry Packer’s Consolidated Press Holdings Ltd took control of ANI. In January 1999, Smorgon Steel Group acquired ANI, which included the Bradken business. The company changed hands again in 2001 when Smorgon Steel Group sold Bradken to Castle Harlan Australian Mezzanine Partners (CHAMP). In 2016 negotiations began for Bradken to be taken over by Hitachi Construction for A$689 million. In April 2017 Bradken became a wholly owned subsidiary of Hitachi Construction Machinery Co. Limited.A collection of black and white images and advertising for Bradford Kendall (Bradken) Wodonga.bradford kendall, wodonga industries, wodonga businesses

Calcite is a common mineral and is found worldwide due to it being a primary component of many other rocks such as limestone and marble. It is a softer mineral that scratches easily and is often found colourless or with a cream/white shade but may show up in colours such as red, yellow, green, and violet. In sedimentary rocks calcite is often found in the form of invertebrate shells, making it an important biomineral. Calcite is used in many industries such as farming, building, and medicine. This particular specimen was found at Broken Hill mine in Broken Hill, New South Wales, Australia. Broken Hill mine is one of the largest mines working silver and lead in Australia and at its peak employed 6500 staff across 7.5km long of land. The site was founded in 1883 by Charles Rasp, where Rasp and 6 other men from various backgrounds came together to form the first BHP mine. It has become one of the most popular mining sites due to its abundance and longevity. The ore body was created 1685 million years ago due to volcanic activity causing heated seawater to flow up through the seafloor where it mixed with the cold water creating black sulphide precipitates. These then settled back onto the seafloor forming sediment layers rich in minerals. Over time the land eroded until it was discoverable by humans.Historically this specimen is significant due to the origin of its location. Broken Hill mine has a long history in both its location and its findings and has resulted in a variety of minerals being discovered at its site. It is beneficial in the understanding of the Australian landscape over millions of years. Due to its properties, calcite today is used in a multitude of different industries such as agriculture, construction, medicine, and farming.A small sized calcium, carbon and oxygen made mineral specimen in shades cream and greycalcite, mineral, limestone, marble, sedimentary, invertebrate shells, biomineral, farming, medicine, broken hill, broken hill mine, new south wales, charles rasp, syndicate of seven, volcanic activity, black sulphide precipitates, calcite crystals, beechworth museum, indigo shire, beechworth
