Genhe (Gegengol) (Mongolian: ; ), formerly Ergun Left Banner or Ergun Zuoqi (), is a city in the far northeast of Inner Mongolia, People's Republic of China.
 It is administratively a county-level city of Hulunbuir City.
The Fairbanks mining district is a gold-mining area in the U.S. state of Alaska.
 Placer mining began near Fairbanks in July 1902, after Felix Pedro (real name Felice Pedroni), an Italian immigrant and Tom Gilmore discovered gold in the hills north of the Tanana and Chena Rivers in 1901.
 Pedro died exactly eight years after finding the richest gold placer he would ever know.
 By 1903 a new rush started, and prospectors staked thousands of claims.
 However, mining results were disappointing during the summer of 1903, with little gold recovered.
 Then Dennis O'Shea struck it rich on Fairbanks Creek, No. 8 Above.
 This was one of the richest claims in the Fairbanks Mining District and paid as high as $136 to the pan (gold @ $20/ounce).
 Discoveries on Cleary and Ester Creeks followed, and almost two-thirds of the gold mined in the Tanana hills before 1910 came from these three creeks.
 Total production of gold was more than $ 30 million.
 Towns grew on every creek with a combined population of 1,600 residents.
Bergslagen is a historically, culturally, and linguistically distinct mining district located north of Lake Mälaren in northern Svealand, Sweden.
 In Bergslagen mining and metallurgic industry have been important since the Middle Ages.
 The region is to be distinguished from Malmfälten ("the Ore Fields"), the mining district of northernmost Sweden centered at the towns of Kiruna and Malmberget, that has been of greater importance during the 20th century.
Victor is a statutory city in Teller County, Colorado, United States.
 Gold was discovered in Victor in the late 19th century, an omen of the future of the town.
 With Cripple Creek, the mining district became the second largest gold mining district in the country and realized approximately $10 billion of mined gold in 2010 dollars.
 It reached its peak around the turn of the century when there were about 18,000 residents in the town.
 Depleted ore in mines, labor strife and the exodus of miners during World War I caused a steep decline in the city's economy, from which it has never recovered.
 The population was 397 at the 2010 census.
 There is a resumed mining effort on Battle Mountain.
Fengfeng Mining District () is a district of the city of Handan, Hebei, People's Republic of China.
The Nome mining district, also known as the Cape Nome mining district, is a gold mining district in the U.S. state of Alaska.
 It was discovered in 1898 when Erik Lindblom, Jafet Lindeberg and John Brynteson, the "Three Lucky Swedes", found placer gold deposits on Anvil Creek and on the Snake River, a few miles from the future site of Nome.
 Word of the strike caused a major gold rush to Nome in the spring of 1899.
Prospect Creek is a very small settlement approximately 180 mi north of present-day Fairbanks and 25 mi southeast of present-day Bettles, Alaska.
 Years ago it was home to numerous mining expeditions and the camp for the building of the Trans-Alaska Pipeline System (TAPS).
 Today, it is the location of Pump Station 5 (Jim River Station) of the TAPS.
 Prospect Creek is also home to the United States record for lowest temperature.
 On January 23, 1971 the record low temperature of -80 F was recorded.
 Wildlife can be found there even with its extreme changes in temperature; local fauna include anything from black and brown bears to bald eagles.
 The elevation of Prospect Creek is 643 ft above sea level.
 Nearby Moore Creek is widely known for its gold and quartz mining and sits alongside Prospect Creek in Alaska’s Innoko Mining District (Moorecreek Mining Line, MML).
 The Innoko Mining District is famous for its findings of large quartz.
Silver City is a ghost town located at the mouth of Dragon Canyon on the west flank of the East Tintic Mountains in northeast Juab County in central Utah, United States.
 It was a silver mining town approximately 90 mi south-southwest of Salt Lake City, Utah.
 This area was considered part of the Tintic Mining District and also produced bismuth, copper, gold, and lead.
 Settlement began with the first mining strikes here in 1869.
 Silver City was inhabited until 1930 after the mines ran out.
 Jesse Knight, known as the "Mormon Wizard" for his ability to find ore easily, decided to build a smelter in Silver City because it had the flattest ground in all of the Tintic Mining District.
 Silver City had several mines in 1890, but the mines hit water and were abandoned.
 Now there is nothing left other than a few holes where mines were, and a number of tailings piles.
The Xiangtangshan Caves () is a group of Buddhist cave temples located in the Fengfeng Mining District about 20 km to the southwest of the City of Handan, in Hebei province, China.
 The oldest cave temples in the group date to the Northern Qi, one of the Northern dynasties in the sixth century, and were sponsored by the dynasty's court.
 The caves are located about 20 km to the northwest of the site of Ye, the capital of the Northern Qi and were carved into dense limestone cliffs on mountains that are part of the Taihang Mountains.
Atwood is a former mining settlement located 35 miles northeast of Mina in Nye County, Nevada.
 Founded in 1901, it was the most important mining village in the Fairplay Mining District, that was called "Atwood Mining District" as well.
 After Atwood was totally deserted in 1908, the settlement revived in 1914.
 The last resident left the mining settlement in 1959.
 Currently, only one foundation and fragments of glass remain.
