Wheal Watkins
Wheal Watkins mine, formerly Wheal Gawler mine, is an historic lead and silver mine in Glen Osmond, South Australia. The mine first operated from 1844 until 1850, and again briefly in 1888 to 1889, and 1916. From 1986 onwards, the mine was accessible by guided tour, until a rockfall event prompted its closure in 2005. Development The Wheal Watkins mine was preceded by the Wheal Gawler mine, which was opened in May 1841. The initial discovery of galena in the field is attributed to James Heneker. The property containing the Wheal Watkins lead and silver deposit was purchased by Mr Watkins of Worthing, England in December 1841. It was purchased through his South Australian agent, Peter Peachey, who opened a mine there on his behalf in 1843. He first worked the deposit in May 1844. The lode was found to contain 70% lead and 30 ounces of silver per ton. The ore was sold in London for £13 13 shillings per ton. The mine's principal contractor was Thomas Williams, and a team of C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glen Osmond, South Australia
Glen Osmond is a suburb of Adelaide, South Australia in the City of Burnside which is in the foothills of the Adelaide Hills. It is well known for the road intersection on the western side of the suburb, where the South Eastern Freeway (National Route M1) from the Adelaide Hills and the main route from Melbourne splits into National Route A17 Portrush Road (north, the main route towards Port Adelaide), Glen Osmond Road, Adelaide (northwest towards Adelaide city centre) and state route A3 Cross Road west towards the coast and southern suburbs. History In 1841, silver and lead were found at Glen Osmond, leading to the establishment of the Wheal Gawler and Wheal Watkins mines. The mines operated in the 1840s, and again in the 1890s. Cedric Stanton Hicks, founder of the Australian Army Catering Corps, died here in 1976.

Surface Mines In Australia
A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of sight and touch, and is the portion with which other materials first interact. The surface of an object is more than "a mere geometric solid", but is "filled with, spread over by, or suffused with perceivable qualities such as color and warmth". The concept of surface has been abstracted and formalized in mathematics, specifically in geometry. Depending on the properties on which the emphasis is given, there are several non equivalent such formalizations, that are all called ''surface'', sometimes with some qualifier, such as algebraic surface, smooth surface or fractal surface. The concept of surface and its mathematical abstraction are both widely used in physics, engineering, computer graphics, and many other disciplines, primarily in representing the surfaces ...

Silver Mines In South Australia
Silver is a chemical element with the symbol Ag (from the Latin ', derived from the Proto-Indo-European ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures. Other than in curre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead Mines In South Australia
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the group, lea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Adelaide
This article details the History of Adelaide from the first human activity in the region to the 20th century. Adelaide is a New town, planned city founded in 1836 and the capital of South Australia. Aboriginal settlement The Adelaide plains were inhabited by the Kaurna people before the colonisation of South Australia, their territory extending from what is now Cape Jervis, South Australia, Cape Jervis to Port Broughton, South Australia, Port Broughton. The Kaurna lived in family groups called ''yerta'', a word which also referred to the area of land which supported the family group. Each yerta was the responsibility of Kaurna adults who inherited the land and had an intimate knowledge of its resources and features. The Kaurna led a nomadic existence within the Yerta confines in large family groups of around 30. The area where the Adelaide city centre now stands was called "Tarndanya", which translates as "male red kangaroo rock", an area along the south bank of what is now c ...

Pickaxe
A pickaxe, pick-axe, or pick is a generally T-shaped hand tool used for Leverage (mechanics), prying. Its head is typically metal, attached perpendicularly to a longer handle, traditionally made of wood, occasionally metal, and increasingly fiberglass. A standard pickaxe, similar to a "mattock, pick mattock", has a pointed end on one side of its head and a broad flat "axe" blade opposite. A gradual curve characteristically spans the length of the head. The next most common configuration features two spikes, one slightly longer than the other. The pointed end is used both for breaking and prying, the axe for hoeing, skimming, and chopping through roots. Developed as agricultural tools in prehistoric times, picks have evolved into other tools such as the plough and the mattock. They also have been used in general construction and traditional mining, mining, and adapted to warfare. Etymology The Oxford Dictionary of English states that both "pick" and "pickaxe" have the ...

Stephen Baker (Australian Politician)
Stephen John Baker (born 30 May 1946) was an Australian politician and 7th Deputy Premier of South Australia from 1993 to 1996. Baker represented the Liberal Party in the electoral district of Waite, formerly Mitcham in the House of Assembly. Hailing from the moderate faction in his party, he won the seat of Mitcham at the 1982 state election from Democrat MP Heather Southcott, the only single-member lower house seat anywhere in Australia to be held by a Democrat. Baker became Deputy Premier and Treasurer in the government of fellow moderate Dean Brown after the 1993 state election, but was deposed as deputy leader in favour of Graham Ingerson when John Olsen was successful in a November 1996 leadership coup. Baker announced his retirement two months before the 1997 state election, which some interpreted as an act of revenge. The hastily conducted preselection resulted in a win for the conservative faction, whose candidate Martin Hamilton-Smith defeated moderate Robert Lawso ...

States And Territories Of Australia
The states and territories are federated administrative divisions in Australia, ruled by regional governments that constitute the second level of governance between the federal government and local governments. States are self-governing polities with incomplete sovereignty (having ceded some sovereign rights to federation) and have their own constitutions, legislatures, departments, and certain civil authorities (e.g. judiciary and law enforcement) that administer and deliver most public policies and programs. Territories can be autonomous and administer local policies and programs much like the states in practice, but are still constitutionally and financially subordinate to the federal government and thus have no true sovereignty. The Federation of Australia constitutionally consists of six federated states (New South Wales, Queensland, South Australia, Tasmania, Victoria, and Western Australia) and ten federal territories,Section 2B, Acts Interpretation Act 1901 out of ...

Register Of The National Estate
The Register of the National Estate was a heritage register that listed natural and cultural heritage places in Australia that was closed in 2007. Phasing out began in 2003, when the Australian National Heritage List and the Commonwealth Heritage List were created and by 2007 the Register had been replaced by these and various state and territory heritage registers. Places listed on the Register remain in a non-statutory archive and are still able to be viewed via the National Heritage Database. History The register was initially compiled between 1976 and 2003 by the Australian Heritage Commission, after which the register was maintained by the Australian Heritage Council. 13,000 places were listed. The expression "national estate" was first used by the British architect Clough Williams-Ellis, and reached Australia in the 1970s.Heritage of Australia, pp. 9–13 It was incorporated into the ''Australian Heritage Commission Act 1975'' and was used to describe a collection o ...
