Shire Of Laverton
The Shire of Laverton is a local government area in the Goldfields-Esperance region of Western Australia, about northeast of the city of Kalgoorlie and about east-northeast of the state capital, Perth. The Shire covers an area of , and its seat of government is the town of Laverton. History The Mount Margaret Road District was gazetted on 17 August 1906. It absorbed the Municipality of Mount Morgans on 28 February 1913. On 13 November 1925, it absorbed some land from neighbouring road districts, most notably Lawlers. It was renamed the Laverton Road District on 20 January 1950.

Prospecting
Prospecting is the first stage of the geological analysis (followed by Mining engineering#Pre-mining, exploration) of a territory. It is the search for minerals, fossils, precious metals, or mineral specimens. It is also known as fossicking. Traditionally prospecting relied on direct observation of mineralization in rock outcrops or in sediments. Modern prospecting also includes the use of geologic, Geophysics, geophysical, and Geochemistry, geochemical tools to search for anomalies which can narrow the search area. Once an anomaly has been identified and interpreted to be a potential prospect direct observation can then be focused on this area. In some areas a prospector must also stake a claim, meaning they must erect posts with the appropriate placards on all four corners of a desired land they wish to prospect and register this claim before they may take samples. In other areas publicly held lands are open to prospecting without staking a mining claim. Historical method ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pastoralism
Pastoralism is a form of animal husbandry where domesticated animals (known as "livestock") are released onto large vegetated outdoor lands (pastures) for grazing, historically by nomadic people who moved around with their herds. The animal species involved include cattle, camels, goats, yaks, llamas, reindeer, horses, and sheep. Pastoralism occurs in many variations throughout the world, generally where environmentally effected characteristics such as aridity, poor soils, cold or hot temperatures, and lack of water make crop-growing difficult or impossible. Operating in more extreme environments with more marginal lands means that pastoral communities are very vulnerable to the effects of global warming. Pastoralism remains a way of life in many geographic areas, including Africa, the Tibetan plateau, the Eurasian steppes, the Andes, Patagonia, the Pampas, Australia and many other places. , between 200 million and 500 million people globally practiced pa ...

Nickel
Nickel is a chemical element; it has symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive, but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classifie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Murrin Murrin Joint Venture
The Murrin Murrin Mine is a major nickel-cobalt mining operation being conducted in the North Eastern Goldfields, approximately 45 km east of Leonora, Western Australia. The project was initiated as a 60/40 joint venture between Murrin Murrin Holdings, a subsidiary of Anaconda Nickel and Glenmurrin, a subsidiary of Glencore. In 2003 Anaconda changed its name to Minara Resources. In November 2011, Minara Resources was acquired by Glencore. The mine opened in 1999.''The Australian Mines Handbook: 2003–2004 Edition'', page: 39 Geology Murrin Murrin mines a laterite nickel ore formed by deep weathering of a peridotite ultramafic rock. Problems with the process plant Significant problems and delays were encountered in the design, construction and commissioning of the ore process plant at Murrin Murrin. The designers, Fluor Daniel eventually had to pay the joint venture partners $155 million in an out-of-court settlement. It was the second successful claim against Fluor, ...

Open-pit Mining
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique that extracts rock (geology), rock or minerals from the earth. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface where the overburden is relatively thin. In contrast, deeper mineral deposits can be reached using underground mining. Open-pit mining is considered one of the most dangerous industrial sector, sectors in the industrial world. It causes significant effects to miners' health, as well as damage to the ecological land and water. Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths. Additionally, open-pit produces harmful pollutants depending on the type of mineral being mined, and the type of mining process being used. Extraction Miners typically drill a series of test holes to locate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Granny Smith Gold Mine
The Granny Smith Gold Mine is a gold mine south of Laverton, Western Australia near Mount Weld and operated by Gold Fields. As of 2022, it is one of four mines the company operates in Australia, the others being the Agnew, Gruyera and St Ives. History The Granny Smith gold deposit was discovered in 1979 by Canadian prospector Ray Lovi Smith and named after his wife Laurende. Construction of the mine took place in the late 1980s. The project was originally owned by Delta Gold, which became Auriongold in February 2002. Aurion was taken over by Placer Dome in 2003, who already held a 60% interest in the mine, and Placer Dome in turn by Barrick Gold in March 2006. A large amount of ore processed at Granny Smith originated from the Wallaby deposit, approximately west of the mine, and was hauled to the Granny Smith mill for processing. Open pit mining at Wallaby ceased in September 2006, followed by a ramp up of underground mining at the location. In February 2009, Barri ...

Gold
Gold is a chemical element; it has chemical symbol Au (from Latin ) and atomic number 79. In its pure form, it is a brightness, bright, slightly orange-yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal, a group 11 element, and one of the noble metals. It is one of the least reactivity (chemistry), reactive chemical elements, being the second-lowest in the reactivity series. It is solid under standard temperature and pressure, standard conditions. Gold often occurs in free elemental (native state (metallurgy), native state), as gold nugget, nuggets or grains, in rock (geology), rocks, vein (geology), veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as in electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining
Mining is the Resource extraction, extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agriculture, agricultural processes, or feasibly created Chemical synthesis, artificially in a laboratory or factory. Ores recovered by mining include Metal#Extraction, metals, coal, oil shale, gemstones, limestone, chalk mining, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even fossil water, water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final mine reclamation, reclamation or restoration of the land after the mine is closed.
