Silver Rush
A silver rush is the silver-mining equivalent of a gold rush, where the discovery of silver-bearing ore sparks a mass migration of individuals seeking wealth in the new mining region. Notable silver rushes have taken place in Mexico, Chile, the United States (Colorado, Nevada, California, Utah), and Canada (Cobalt, Ontario, and the Kootenay district of British Columbia). Several famous tourist towns owe their existence to silver rushes. History Historically there were other "silver rushes", such as on the Attic peninsula near Athens, Greece, thousands of years ago. The silver mines of Laurion became famous for their exploitation and helped fund the new state of Athens. The term is also widely applied to the New World. Despite the larger-than-life image of the gold rush, the history of towns and industry in the North American West revolves much more around silver. This is partly because of the other minerals usually found with it – lead, tin, copper – and the more complica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver Mining
Silver mining is the extraction of silver by mining. Silver is a precious metal and holds high economic value. Because silver is often found in intimate combination with other metals, its extraction requires the use of complex technologies. In 2008, approximately 25,900 metric tons of silver were consumed worldwide, most of which came from mining. Silver mining has a variety of effects on the environment, humans, and animals. Silver sources Silver-bearing ore typically contains very little silver, with much higher percentages of copper and lead. Specific minerals include argentite (Ag2 S), chlorargyrite ("horn silver," Ag Cl), polybasite (Ag, Cu)16Sb2S11), and proustite (Ag3AsS3). Silver mainly occurs as a contaminant in chalcopyrite and galena, important ores of copper and lead, respectively.Kassianidou, V. 2003.

Laurion
Lavrio, Lavrion or Laurium (; (later ); from Middle Ages until 1908: Εργαστήρια ''Ergastiria'') is a town in southeastern part of Attica Region, Attica, Greece. It is part of Athens metropolitan area and the seat of the municipality of Lavreotiki. Laurium was famous in Classical antiquity for its Mines of Laurion, silver mines, which was one of the chief sources of revenue of the Ancient Athens, Athenian state. The metallic silver was mainly used for coinage. The Archaeological Museum of Lavrion shows much of the story of these mines. It is located about 60 km SE of Athens city center, SE of Keratea and N of Sunium, Cape Sounio. Laurium is situated on a bay overlooking the island of Makronisos (ancient times: Helena) in the east.

Klondike, Yukon
The Klondike (; ) is a region of the territory of Yukon, in northwestern Canada. It lies around the Klondike River, a small river that enters the Yukon River from the east at Dawson City. The area is merely an informal geographic region, and has no function to the territory as any kind of Administrative division, administrative region. The Klondike is famed due to the Klondike Gold Rush, which started in 1896 and lasted until 1899. Since then, gold has been mined continuously in that area, except for a pause in the late 1960s and early 1970s. In 2023, the cultural landscape of the Tr’ondëk-Klondike was inscribed as a UNESCO World Heritage Site, because of its testimony to the adaptation of the Tr’ondëk Hwëch’in people to the European colonization that began in the late 19th century. Climate and ecology Klondike has a subarctic climate (Köppen climate classification, Köppen ''Dfc''), bordering on a tundra climate (Köppen climate classification, Köppen ''ET''). The cl ...

Dawson City, Yukon
Dawson City is a town in the Canadian territory of Yukon. It is inseparably linked to the Klondike Gold Rush (1896–1899). Its population was 1,577 as of the 2021 census, making it the second-largest municipality in Yukon. History Prior to the late modern period the area was used for hunting and gathering by the Hän-speaking people of the Tr’ondëk Hwëch’in and their forebears. The heart of their homeland was Tr'ochëk, a fishing camp at the confluence of the Klondike River and Yukon River, now a National Historic Site of Canada, just across the Klondike River from modern Dawson City. This site was also an important summer gathering spot and a base for moose-hunting on the Klondike Valley. The current settlement was founded by Joseph Ladue and named in January 1897 after noted Canadian geologist George M. Dawson, who had explored and mapped the region in 1887. It served as Yukon's capital from the territory's founding in 1898 until 1952, when the seat was moved ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Placer Mining
Placer mining () is the mining of stream bed deposits for minerals. This may be done by open-pit mining or by various surface excavating equipment or tunneling equipment. Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are often found in alluvial deposits—deposits of sand and gravel in modern or ancient stream beds, or occasionally glacial deposits. The metal or gemstones, having been moved by stream flow from an original source such as a vein, are typically only a minuscule portion of the total deposit. Since gems and heavy metals like gold are considerably denser than sand, they tend to accumulate at the base of placer deposits. Placer deposits can be as young as a few years old, such as the Canadian Queen Charlotte beach gold placer deposits, or billions of years old like the Elliot Lake uranium paleoplacer within the Huronian Supergroup in Canada. The containing material in an alluvial placer mine may be too lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ghost Town
A ghost town, deserted city, extinct town, or abandoned city is an abandoned settlement, usually one that contains substantial visible remaining buildings and infrastructure such as roads. A town often becomes a ghost town because the economic activity that supported it (usually industrial or agricultural) has failed or ended for any reason (e.g. a host ore deposit exhausted by mining). The town may have also declined because of natural or human-caused disasters such as floods, prolonged Drought, droughts, extreme heat or extreme cold, government actions, uncontrolled lawlessness, war, pollution, or nuclear and radiation accidents and incidents, nuclear and radiation-related accidents and incidents. The term can sometimes refer to cities, towns, and neighborhoods that, though still populated, are significantly less so than in past years; for example, those affected by high levels of unemployment and dereliction. Some ghost towns, especially those that preserve period-specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Boundary Country
The Boundary Country is a historical designation for a district in southern British Columbia lying, as its name suggests, along the boundary between Canada and the United States. It lies to the east of the southern Okanagan Valley and to the west of the West Kootenay.

Galena
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the Cubic (crystal system), cubic crystal system often showing octahedral forms. It is often associated with the minerals sphalerite, calcite and fluorite. As a pure specimen held in the hand, under standard temperature and pressure, galena is insoluble in water and so is almost non-toxic. Handling galena under these specific conditions (such as in a museum or as part of geology instruction) poses practically no risk; however, as lead(II) sulfide is reasonably reactive in a variety of environments, it can be highly toxic if swallowed or inhaled, particularly under prolonged or repeated exposure. Occurrence Galena is the main ore of lead, used since ancient times, since lead can be smelted from galena in an ordinary wood fire. G ...
