A gold rush or gold fever is a discovery of gold—sometimes accompanied by other precious metals and rare-earth minerals—that brings an onrush of miners seeking their fortune. Major gold rushes took place in the 19th century in Australia, Greece, New Zealand, Brazil, Chile, South Africa, the United States, and Canada while smaller gold rushes took place elsewhere.
Chuquicamata is the largest open pit copper mine in terms of excavated volume in the world. It is located in the north of Chile, just outside Calama, at 2,850 m (9,350 ft) above sea level. It is 215 km (134 mi) northeast of Antofagasta and 1,240 km (770 mi) north of the capital, Santiago. Flotation and smelting facilities were installed in 1952, and expansion of the refining facilities in 1968 made 500,000 tons annual copper production possible in the late 1970s. Previously part of Anaconda Copper, the mine is now owned and operated by Codelco, a Chilean state enterprise, since the Chilean nationalization of copper in the late 1960s and early 1970s. Its depth of 850 metres (2,790 ft) makes it the second deepest open-pit mine in the world, after Bingham Canyon Mine in Utah, United States.
Gilman is an abandoned mining town in southeastern Eagle County, Colorado, United States. The Gilman post office operated from November 3, 1886, until April 22, 1986. The U.S. Post Office at Minturn now serves Gilman postal addresses.
The Village of Slocan is in the West Kootenay region of southeastern British Columbia. The former steamboat landing and ferry terminal is at the mouth of Springer Creek, at the foot of Slocan Lake. The locality, on BC Highway 6 is about 69 kilometres (43 mi) by road north of Castlegar and 183 kilometres (114 mi) by road and ferry south of Revelstoke.
Silver mining is the extraction of silver from minerals, starting with mining. Because silver is often found in intimate combination with other metals, its extraction requires elaborate technologies. In 2008, ca. 25,900 metric tons were consumed worldwide, most of which came from mining.
Mining was one of the most prosperous activities in Roman Britain. Britain was rich in resources such as copper, gold, iron, lead, salt, silver, and tin, materials in high demand in the Roman Empire. Sufficient supply of metals was needed to fulfil the demand for coinage and luxury artefacts by the elite. The Romans started panning and puddling for gold. The abundance of mineral resources in the British Isles was probably one of the reasons for the Roman conquest of Britain. They were able to use advanced technology to find, develop and extract valuable minerals on a scale unequaled until the Middle Ages.
Silver mining in the United States began on a major scale with the discovery of the Comstock Lode in Nevada in 1858. The industry suffered greatly from the demonetization of silver in 1873 by the Coinage Act of 1873, known pejoratively as the "Crime of 73", but silver mining continues today.
Gold mining in Colorado, a state of the United States, has been an industry since 1858. It also played a key role in the establishment of the state of Colorado.
Silver mining in Colorado has taken place since the 1860s. In the past, Colorado called itself the Silver State.
Silver mining in Nevada, a state of the United States, began in 1858 with the discovery of the Comstock Lode, the first major silver-mining district in the United States. Nevada calls itself the "Silver State." Nevada is the nation's second-largest producer of silver, after Alaska. In 2014 Nevada produced 10.93 million troy ounces of silver, of which 6.74 million ounces were as a byproduct of the mining of gold. The largest byproducers were the Hycroft Mine, the Phoenix Mine, the Midas Mine and Round Mountain.
The Leadville mining district, located in the Colorado Mineral Belt, was the most productive silver-mining district in the state of Colorado and hosts one of the largest lead-zinc-silver deposits in the world. Oro City, an early Colorado gold placer mining town located about a mile east of Leadville in California Gulch, was the location to one of the richest placer gold strikes in Colorado, with estimated gold production of 120,000–150,000 ozt, worth $2.5 to $3 million at the then-price of $20.67 per troy ounce.
The following outline is provided as an overview of and topical guide to mining:
Castle Dome Landing, Arizona is a ghost town in the Castle Dome Mountains of Yuma County in the U.S. state of Arizona. It was first settled as a transport depot and mining camp around 1863 in what was then the Arizona Territory.
Chañarcillo is a town and mine in the Atacama Desert of Copiapó Province, Atacama Region, Chile, located near Vallenar and 60 km from Copiapó. It is noted for its silver mining. The town grew after the Chañarcillo silver mine was discovered on May 16, 1832, by Juan Godoy. This event sparkled the Chilean silver rush. It grew in prominence in the second half of the nineteenth century and became important in the Atacama mining industry and one of the most important mines to the Chilean economy. It was connected by railway before 1862. Today the settlement is largely in ruins.
Gold Trails and Ghost Towns is a Canadian historical documentary show, created and produced by television station CHBC-TV in Kelowna, British Columbia for Canadian syndication and hosted by Mike Roberts with historian/storyteller Bill Barlee. The show was filmed in a studio which resembled an old trapper's cabin. Mike and Bill discussed prospectors and the history of British Columbia around 1900.
Priest Mine is an abandoned surface and underground mine in Northeastern Ontario, Canada. It is located about 19 km (12 mi) northwest of the hamlet of Marten River on an island in north-central Cross Lake. Dating back to the early 1900s, it is one of the oldest mines in the municipality of Temagami.
Between 1830 and 1850, Chilean silver mining grew at an unprecedented pace which transformed mining into one of the country's principal sources of wealth. The rush caused rapid demographic, infrastructural, and economic expansion in the semi-arid Norte Chico mountains where the silver deposits lay. A number of Chileans made large fortunes in the rush and made investments in other areas of the economy of Chile. By the 1850s, the rush was in decline and lucrative silver mining definitively ended in the 1870s. At the same time, mining activity in Chile reoriented to saltpetre operations.
During most of Chile's history, from 1500 to the present, mining has been an important economic activity. 16th century mining was oriented towards the exploitation of gold placer deposits using encomienda labour. After a period of decline in the 17th century mining resurged in the 18th and early 19th century this time revolving chiefly around silver. In the 1870s silver mining declined sharply. Chile took over the highly lucrative saltpetre mining districts of Peru and Bolivia in the War of the Pacific (1879–83). In the first half of the 20th century copper mining overshadowed the declining saltpetre mining.
Caracoles was a silver mining district in what is now Antofagasta Region, Chile. At the time of official discovery in 1870 the district was located in Bolivia. The silver ores of Caracoles were discovered on March 24, 1870, by a Chilean prospecting team led by José Díaz Gana that had departed from the port town of Antofagasta. Subsequently the orescame to be extracted with Chilean capital and miners. It was the last major discovery of the Chilean silver rushes. According to Oreste Plath "some old miners believe that" Caracoles was discovered much earlier, presumably in 1811, by two Aragonese men who were escaping persecution during the independence era. Subsequently, the location of the outcrop is said to have been forgotten. The site of Caracoles evolved rapidly from a series of rudimentary shelts and huts in 1870 to a small hamlet in 1871. Afterwards the settlement continued to grow reaching a population of several thousand inhabitants.
Punta del Cobre Formation is a geologic formation of Early Cretaceous age cropping out in the interior of Atacama Region, Chile. The formation is of Early Cretaceous age. It is made of massive volcanic rocks, chiefly andesite, dacite, and volcaniclastic rocks representing "flows" and Volcanic breccia of basaltic andesitic and basaltic composition. The rocks of the formation belong to the calc-alkaline magma series. Rocks show intense hydrothermal alteration and hosts significant copper and gold deposits and lesser amounts of zinc and silver. The formation lies in a zone of small-scale mining that supplies the nearby Fundición de Paipote copper smelter. The copper and iron ores of the Dominga prospect are in part emplaced in Punta del Cobre Formation.
