This specimen was recovered from Mica Schist, Canada. Chalcopyrite is a copper iron sulfide mineral with a chemical composition of CuFeS2. Its name derives from the Greek words for copper (chalco-) and brass (pyrite). It can be found in shades of yellow, green and grey, and, when exposed to acid, it can change to purple, blue, violet and yellow tones. Weathering can cause loss of its metallic luster and its brass-yellow colour. Chalcopyrite forms under various conditions, with the most significant deposits being hydrothermal in their origin. It is known globally as the most important ore of copper for thousands of years, and is thus considered a very important mineral formation. Given its golden appearance, it is often confused for the mineral gold, earning it the popular reputation as 'fool's gold' or 'yellow copper'. However, it can be straightforwardly distinguished from gold; the latter is soft, with higher specific gravity and a yellow streak, whereas chalcopyrite is brittle, easily scratched by a nail, and has a greenish grey streak. Copper was the first metal that was used by people. It was discovered by the Neolithic man about 9,000 years ago and it gradually replaced stone as it was easier to be shaped. In Australia, search for copper began after the European settlement, leading to the discovery of substantial deposits, like the one at the Olympic Dam in South Australia, which is regarded as one of the largest copper deposits in the world. Chalcopyrite has been used for copper since smelting processes began approximately five thousand years ago. Although by no means rare, this the specimen of this mineral can be used to reflect a wider history of industrial uses of copper for a significant portion of human history. 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 solid hand-sized copper iron sulfide mineral of brass yellow, often with an iridescent tarnish, with greenish-black streak and submetallic luster. Chalcopyrite can be formed in several ways, including crystalizing from accessory minerals in igneous rocks, or from magma or within volcano sulfide deposits. Most commonly, chalcopyrite are found in hydrothermal conditions, where it forms in hydrothermal veins. As a member of the tetragonal crystal system, it often takes the shape of tetra-headed crystals, often with striations along the sides of the crystals. #18 Copper pyrites/(chalcopyrite) in/Laurentian Slate/(page 315 of inventory)/page missing from/descriptive catalogue/ Other label: 81 /fool's gold, chalcopyrite, mineral, rock, geology, geological, hydrothermal, neolithic, european settlement, olympic dam, south australia, stone, deposits, specific gravity, greenish grey streak, brittle, mineral gold, metallic luster, cufes2, greek words

Gold usually is found as a native metal, but it also forms minerals with tellurium, sulphur, or selenium. The gold-bearing minerals that contain tellurium are called tellurides. Kalgoorlie, Western Australia contains greater than 1500 tonnes of gold.Seventy to seventy-five percent of the deposit occurs as native gold, but a further twenty percent appears as tellurides. What remains is in the form of 'invisible' gold. Extracting gold from telluride minerals, such as calaverite, which contains around forty-two percent gold, has produced approximately three hundred tonnes of gold. Prior to 1896, rocks containing tellurides were not recognised as rich gold ores, and were discarded.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.

Gold was discovered in Victoria c1850 and people came from all over the world to seek their fortune at Ballarat and Bendigo and surrounding gold fields. This large wooden rocking- box or cradle was used by gold prospectors. A handle on the rocker is pushed back and forth, as the miner put gravel into the top part and finer and heavier particles dropped through a screen, helped along by buckets of water. The bottom part of the device had slats, that caught the heavier metals. After many shovel loads of gravel were pushed through the rocker, the miner would then use his gold pan to sort out the heavy minerals to find gold. Most of the pioneer settlers in Moorabbin Shire left the area to try their luck at gold mining and there was a desperate shortage of workers to maintain the market gardens and supply food to the ever increasing population of Melbourne.This gold prospector's 'cradle' is hand made and typical of those used by many hopeful Moorabbin Shire pioneers as they abandoned their market gardens to try their luck at finding gold in the Ballarat and Bendigo minefields c1850This gold miner's rocker is very old, and very well-used.

Taken on 14 May 1979, this photo depicts Mr Alan J. Dunlop and his wife presenting a 2.86-gram solid gold nugget found in the Beechworth area more than 100 years ago, to the Shire President, Councillor Mrs Valerie Mason. The gold is reported as attached to a small amount of milk quartz mounted onto a tie pin, and was donated to the Burke Museum by the Dunlop family. Alan Dunlop, pictured, was Sir Edward 'Weary' Dunlop's older brother. The tie pin artefact being donated in this photograph is entered into the Victorian Collections, and records that the nugget was found in the Beechworth Goldfields by Mr Fred McIntosh, in the last 1800s. Fred McIntosh, the husband of Elizabeth (Bessie) Dunlop (the sister of Alan & Edward's father, John) had the nugget made into tie pin and presented it to the Dunlop Family. Furthermore, Valerie 'Val' Mason was the first female president of the former Beechworth Shire for two terms and a councillor for nine years. This photograph is of historic significance as it depicts known individuals who have connections to key Australian figures. Alan Dunlop is the brother of famous war doctor Edward 'Weary' Dunlop, and both men are Beechworth locals. The object Alan holds is a tie pin made from gold found by the Dunlops' uncle, and the provenance of the item – from goldfield to family collection to museum collection – provides a recent context with which to interpret the significance of gold-mining on present and future generations, as well as strong research potential on minerals known to be sourced in the area. In conjunction with other photographs in the collection, this photograph visually documents the donation and acquisition of the tie pin artefact into the Burke Museum Collection. In addition, it depicts Valerie ‘Val’ Mason, in her role as the president of the former Beechworth Shire. Val was the first female in this role, which she held for two terms, and was a councillor in the Shire for nine years. This photograph is of social significance as it depicts two well-known and respected Beechworth locals handling a key artefact of significance to the Beechworth Goldfields. It also shows the Burke Museum in 1979, providing research potential for those interested in the history of the development of the museum's collection.

Malachite is typically found as crystalline aggregates or crusts, often banded in appearance, like agates. It is also often found as botryoidal clusters of radiating crystals, and as mammillary aggregates as well. Single crystals and clusters of distinguishable crystals are uncommon, but when found they are typically acicular to prismatic. It is also frequently found as a pseudomorph after Azurite crystals, which are generally more tabular in shape. This particular specimen was recovered from the Burra Burra Copper Mine in Burra, South Australia. Otherwise known as the 'Monster Mine', the Burra Burra Copper Mine was first established in 1848 upon the discovery of copper deposits in 1845. Within a few short years, people from around the world migrated to Burra to lay their claim in the copper economy. By April 1848 the mine was employing over 567 people and supporting a population of 1,500 in the local township. Up until 1860, the mine was the largest metals mine in Australia, producing approximately 50,000 tonnes of copper between 1845 to its closure in 1877. The Burra Burra Mine was also famous for a number of other specimens, including; crystalline azurite, cuprite, and botryoidal and malachite. Malachite is considered a rare gemstone in that the original deposits for the stones have been depleted leaving behind very few sources. In addition, the use of Malachite as gemstones and sculptural materials remains just as popular today as they were throughout history. It is quite common to cut the stone into beads for jewellery. The fact that Malachite has such a rich colour and one that does not fade with time or when exposed to light makes it particularly rare. 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.
