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.
Ballycorusleadmines is a former lead mining and smelting centre located in the townland of the same name, near Kilternan in County Dublin, Ireland. The mine opened around 1807 and was taken over by the Mining Company of Ireland (MCI) in 1826 who owned and operated the site up until closure in 1913. After the mine was exhausted in the 1860s, Ballycorus continued to operate as a smelting facility receiving ore from other MCI sites such as the mines in Glendalough, County Wicklow. The most distinctive surviving remnant of the site is the ruin of the flue chimney that lies close to the summit of Carrickgollogan hill. Further down the slopes of the hill, many other former buildings and structures from the leadworks can also be found.
The Silver Valley is a region in the northwest United States, in the Coeur d'Alene Mountains in northern Idaho. It is noted for its mining heritage, dating back to the 1880s.
In the United States, copper mining has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2017, the US produced 1.27 million metric tonnes of copper, worth $8 billion, making it the world's fourth largest copper producer, after Chile, China, and Peru. Copper was produced from 23 mines in the US. Top copper producing states in 2014 were Arizona, Utah, New Mexico, Nevada, and Montana. Minor production also came from Idaho and Missouri. As of 2014, the US had 45 million tonnes of known remaining reserves of copper, the fifth largest known copper reserves in the world, after Chile, Australia, Peru, and Mexico.
In the United States, gold mining has taken place continually since the discovery of gold at the Reed farm in North Carolina in 1799. The first documented occurrence of gold was in Virginia in 1782. Some minor gold production took place in North Carolina as early as 1793, but created no excitement. The discovery on the Reed farm in 1799 which was identified as gold in 1802 and subsequently mined marked the first commercial production.
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.
Uranium mining in Colorado, United States, goes back to 1872, when pitchblende ore was taken from gold mines near Central City, Colorado. The Colorado uranium industry has seen booms and busts, but continues to this day. Not counting byproduct uranium from phosphate, Colorado is considered to have the third largest uranium reserves of any US state, behind Wyoming and New Mexico.
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.
Uranium mining in Utah, a state of the United States, has a history going back more than 100 years. Uranium mining started as a byproduct of vanadium mining about 1900, became a byproduct of radium mining about 1910, then back to a byproduct of vanadium when the radium price fell in the 1920s. Utah saw a uranium boom in the late 1940s and early 1950s, but uranium mining declined in the 1980s. Since 2001 there has been a revival of interest in uranium mining, as a result of higher uranium prices.
Uranium mining in Arizona has taken place since 1918. Prior to the uranium boom of the late 1940s, uranium in Arizona was a byproduct of vanadium mining of the mineral carnotite.
Austin Creek is a 16.0-mile-long (25.7 km) southward-flowing stream in the mountains of western Sonoma County, California which empties into the Russian River about 4 miles (6 km) from the Pacific Ocean.
Wonder, Nevada, is a ghost town in Churchill County, Nevada, approximately 39 miles (63 km) east of Fallon.
Mining in Afghanistan was controlled by the Ministry of Mines and Petroleum, prior to the August 15th takeover by the Taliban. It is headquartered in Kabul with regional offices in other parts of the country. Afghanistan has over 1,400 mineral fields, containing barite, chromite, coal, copper, gold, iron ore, lead, natural gas, petroleum, precious and semi-precious stones, salt, sulfur, lithium, talc, and zinc, among many other minerals. Gemstones include high-quality emeralds, lapis lazuli, red garnet and ruby. According to a joint study by The Pentagon and the United States Geological Survey, Afghanistan has an estimated US$1 trillion of untapped minerals.
Golesh is a mountain in central Kosovo, 1,019 m (3,343 ft) high, near the town of Kosovo Polje and Pristina International Airport Adem Jashari.
The Santa Teresa Hills are a range of mountains in Santa Clara County, California, located primarily in the city of San Jose. They separate the San Jose neighborhoods of Almaden Valley to the west and Santa Teresa to the east.
Table Mountain is a narrow, 18 mi (29 km)-long, sinuous, flat-topped ridge separated by erosional saddles into a series of mesas that extend from Lake Tulloch to just west of Columbia, California in Tuolumne County, California. It is just over 1,100 ft (340 m) in elevation at its southern end and just over 2,000 ft (610 m) in elevation at its northern end. Its flat top is part of a stack of multiple 80 mi (130 km)-long lava flows that have been eroded to form a series of mesas that extend from Knights Ferry to Sonora, California. Its crest varies in width from a narrow ridge to over 1,100 ft (340 m) wide. It parallels the adjacent Stanislaus River.
McCauley Mountain is a mountain in Columbia County, Pennsylvania, in the United States. Its official elevation is 1,571 feet (479 m) above sea level. The mountain is a synclinal mountain. Main rock formations on and near it include the Mauch Chunk Formation and the Pottsville Formation. There are also coal deposits on it. The coal deposits were discovered in 1826 and mining of them began in the 1850s. However, coal mining on the east side of the mountain proved to be a commercial failure. There are a number of ponds on the mountain, some of which were created during the mining. However, others are natural vernal pools. Some of the ponds are surrounded by hemlocks and deciduous trees. Major streams near the mountain include Scotch Run, Beaver Run, and Catawissa Creek. The mountain is named after Alexander McCauley, who settled there in 1774.
Yellow Aster Mine was a large gold mine in Southern California.
