The Red Hill Mine at Sovereign Hill is a mine in Ballarat East, Victoria, Australia, that was one of the first major mines in the Eureka Stockade. It has tours led by a voice that trails the visitor through the mine. [1] It is 76 steps down and roughly 100 steps across. Another major mine is The Sovereign Hill Quartz Mine which produces quartz.
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.
A pegmatite is an igneous rock showing a very coarse texture, with large interlocking crystals usually greater in size than 1 cm (0.4 in) and sometimes greater than 1 meter (3 ft). Most pegmatites are composed of quartz, feldspar, and mica, having a similar silicic composition to granite. However, rarer intermediate composition and mafic pegmatites are known.
The Gold Country is a historic region in the northern portion of the U.S. state of California, that is primarily on the western slope of the Sierra Nevada. It is famed for the mineral deposits and gold mines that attracted waves of immigrants, known as the 49ers, during the 1849 California Gold Rush.
Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals.
The Victorian gold rush was a period in the history of Victoria, Australia, approximately between 1851 and the late 1860s. It led to a period of extreme prosperity for the Australian colony, and an influx of population growth and financial capital for Melbourne, which was dubbed "Marvellous Melbourne" as a result of the procurement of wealth.
Stawell, is an Australian town in the Wimmera region of Victoria 237 kilometres (147 mi) west-north-west of the state capital, Melbourne. Located within the Shire of Northern Grampians local government area, it is a seat of local government for the shire and its main administrative centre. At the 2021 census, Stawell had a population of 6,220.
Sovereign Hill is an open-air museum in Golden Point, a suburb of Ballarat, Victoria, Australia. Sovereign Hill depicts Ballarat's first ten years after the discovery of gold there in 1851. It was officially opened on 29 November 1970 and has become a nationally acclaimed tourist attraction. It is one of Victoria's most popular attractions and Ballarat's most famous.
Empire Mine State Historic Park is a state-protected mine and park in the Sierra Nevada mountains in Grass Valley, California, U.S. The Empire Mine is on the National Register of Historic Places, a federal Historic District, and a California Historical Landmark. Since 1975 California State Parks has administered and maintained the mine as a historic site. The Empire Mine is "one of the oldest, largest, deepest, longest and richest gold mines in California". Between 1850 and its closure in 1956, the Empire Mine produced 5.8 million ounces of gold, extracted from 367 miles (591 km) of underground passages.
Asind is a city and a municipality in Bhilwara district, Rajasthan, India. It is a Tehsil (sub-division) for many villages The city have a magistrate office, lower justice court and many administrative hub for many major villages.
The Georgia Gold Rush was the second significant gold rush in the United States and the first in Georgia, and overshadowed the previous rush in North Carolina. It started in 1829 in present-day Lumpkin County near the county seat, Dahlonega, and soon spread through the North Georgia mountains, following the Georgia Gold Belt. By the early 1840s, gold became difficult to find. Many Georgia miners moved west when gold was found in the Sierra Nevada in 1848, starting the California Gold Rush. Since the 16th century, American Indians in Georgia told European explorers that the small amounts of gold which they possessed came from mountains of the interior. Some poorly documented accounts exist of Spanish or French mining gold in North Georgia between 1560 and 1690, but they are based on supposition and on rumors passed on by Indians. In summing up known sources, W.S. Yeates observed: "Many of these accounts and traditions seem to be quite plausible. Nevertheless, it is hardly probable that the Spaniards would have abandoned mines which were afterwards found to be quite profitable, as those in North Georgia."
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 Porcupine Gold Rush was a gold rush that took place in Northern Ontario starting in 1909 and developing fully by 1911. A combination of the hard rock of the Canadian Shield and the rapid capitalization of mining meant that smaller companies and single-man operations could not effectively mine the area, as opposed to earlier rushes where the gold could be extracted through placer mining techniques. Although a number of prospectors made their fortune, operations in the area are marked largely by the development of larger mining companies, and most people involved in the mining operations were their employees.
Quartz reef mining is a type of gold mining in "reefs" (veins) of quartz. Quartz is one of the most common minerals in the earth's crust, and most quartz veins do not carry gold, but those that have gold are avidly hunted by prospectors. In the shallow, oxidized zones of quartz reef deposits, the gold occurs in its metallic state, and is easily recovered with simple equipment. Quartz reef mining played an important role in 19th century gold-mining districts such as Bendigo, Victoria in Australia, Central Otago in New Zealand, and the California mother lode.
Gold was discovered in the Yentna-Cache Creek Mining District in the U.S. state of Alaska of the upper Susitna River Valley in 1898, soon followed by claim staking. Placer mining was reported in the Cache Creek drainage of the Dutch Hills by 1906. Quaternary glaciofluvial deposits, alluvial deposits, and Cenozoic conglomeratic white quartz-breccia units have been mined in the Dutch Hills. About 200,000 oz of gold has been produced from these placer deposits. By 1927, a road from Talkeetna was constructed into the mining area, known today as The Petersville Road. The mining camp of Petersville, Alaska served as the area Post Office for several years in the late 1920s and early 1930s. Two areas have been set aside for recreational gold mining, the North and South units of the Petersville State Recreation Mining Areas. Many smaller one-man and family placer mining operations continue today.
Gold Hill in Grass Valley, California, was the site of one of the first discoveries of quartz gold in California. While quartz gold was also found in other areas of Nevada County, California during the same time, it is this find near Wolf Creek that led to quartz-mining frenzy and subsequent creation of the Gold Country quartz-mining industry. The location is honored as a California Historical Landmark.
Sebastopol was a historic mining community located on the San Juan Ridge, about 13 miles north of Nevada City. It lay midway between Sweetland and North San Juan, around the intersection of modern Sweetland and School Roads, at an elevation of about 2000 feet.
Tigerville or Tiger City (1878–1885) is a ghost town in the Black Hills of Pennington County, South Dakota, United States. The old mining town exemplifies the boom-and-bust fate of many Western towns.
Needle Hill or Cham Shan is a mountain in New Territories, Hong Kong. It has an altitude of 532 m. This is a part of a popular hiking route including Grassy Hill and Tai Mo Shan. The mountain got its name due to the resemblance of a needle by its peak.
Mottramite is an orthorhombic anhydrous vanadate hydroxide mineral, PbCu(VO4)(OH), at the copper end of the descloizite subgroup. It was formerly called cuprodescloizite or psittacinite (this mineral characterized in 1868 by Frederick Augustus Genth). Duhamelite is a calcium- and bismuth-bearing variety of mottramite, typically with acicular habit.
The Coromandel Gold Rushes on the Coromandel Peninsula and around the nearby towns of Thames and Waihi in New Zealand in the nineteenth century were moderately successful. Traces of gold were found about 1842. A small find was made near Coromandel in 1852; and a larger find in August 1867 when there was a modest rush. But Thames acquired a reputation for speculative holding of unworked ground despite regulations designed to check it, and some miners left for Queensland. Most of the gold was in quartz reefs rather than in more accessible alluvial deposits and had to be recovered from underground mines and extracted using stamping batteries.
