The Con Mine (1938-2003) was the first gold mine developed in the Northwest Territories, Canada, just south of Yellowknife.
 The property was staked by Consolidated Mining and Smelting Company of Canada (Cominco) in September 1935 in response to the discovery of visible gold nearby; the name "Con" is an abbreviation of "Consolidated".
 The advent of winter prevented any prospecting from being conducted, but work in the summer of 1936 led to the discovery of numerous gold veins.
 The Con Mine entered production in 1938 and ceased operations in 2003.
 It has produced over 5000000 ozt of gold from 12,195,585 tons of ore processed.
 The mine was over 6000 ft deep.
The Dvoinoye Gold Mine is an underground gold mine in the Bilibinsky District of the Chukotka Autonomous Okrug of Russia.
 The mine is owned by Canadian mining company Kinross Gold and is approximately 100 km from their Kupol Gold Mine.
 Originally the site of a surface mine, Kinross acquired the property in 2010, and built the underground mine at a cost of US$360-million.
 The mine began production in 2013.
The Franklin-Creighton Mine was a Georgia Gold Rush gold mine located off what is now Yellow Creek Road in the town of Ball Ground in Cherokee County, Georgia.
 The mine, located along the Etowah River, was initially known as the Franklin Mine because it was started by a widow, Mrs. Mary G. Franklin, who obtained a 40 acre lot in the Gold Lottery of 1832.
 Around 1883, the mine became known as the Creighton Mine or the Franklin-Creighton Mine.
 This mine was one of the most productive and continued to operate many years after other area mines had ceased operations.
 Some estimate that it was yielding $1000 per day in 1893 and others place its total production after 1880 at as much as $1,000,000.
 The mine was shut down in 1913 as a result of a collapsed shaft which caused the mine to flood.
The Vulture Mine was a gold mine and settlement in Maricopa County, Arizona, United States.
 The mine began in 1863 and became the most productive gold mine in Arizona history.
 From 1863 to 1942, the mine produced 340,000 ounces of gold and 260,000 ounces of silver.
 Historically, the mine attracted more than 5,000 people to the area, and is credited with founding the town of Wickenburg, Arizona.
 The town that served the mine was known as Vulture City.

Crisson Mine was a gold mine in Lumpkin County, Georgia, USA, located just east of Dahlonega.
 Like many mines in the area, the property probably started as a placer mine during the Georgia Gold Rush.
 Once the placer deposits had been exhausted, an open pit gold mine was established in 1847 and commercial operations continued until the early 1980s.
 A small stamp mill was also established here.
 Much of the gold used for the gold leaf dome of the Georgia State Capitol was mined at this mine, which was among the most productive mine in the Georgia Gold Belt.
 The mine is located just north of the site of the Consolidated Mine, which is itself north of and the Calhoun Mine.
The Tundra Mines was a gold producer in the Northwest Territories, Canada between 1964 and 1968, producing 104,476 troy ounces (3250 kg) of gold from 187,714 tons of ore.

 Indian and Northern Affairs Canada has a project to remediate the Tundra Mine site under their Northern Contaminants Program, funded by the Canadian Federal Contaminated Sites Action Plan.
The Salmita Mine was a gold producer in the Northwest Territories, Canada during 1983 to 1987.
 The deposit was first discovered in 1945 and underground exploration was carried out in 1951-1952.
 It was reactivated for exploration by Giant Yellowknife Mines Limited in 1975 and entered production in 1983.
 They used the old camp and milling plant of the abandoned Tundra Mine, located a few kilometres to the south.
 The mine produced 179,906 troy ounces (5596 kg) of gold from the milling of 238,177 tons of ore.
Mining is important to the national economy of Mongolia.
 Coal, copper, and gold are the principal reserves mined in Mongolia.
 Several gold mines are located about 110 km north of Ulaanbaatar, such as Boroo Gold Mine and Gatsuurt Gold Mine.
 Khotgor Coal Mine is an open-pit coal mining site about 120 km west of Ulaangom.
 Ömnögovi Province in the south of Mongolia is home to large scale mining projects such as the Tavan Tolgoi coal mine and the Oyu Tolgoi copper mine.
 Oyu Tolgoi mine is reported to have the potential to boost the national economy by a third but is subject to dispute over how the profits should be shared.
 The International Monetary Fund (IMF) has estimated that 71 percent of the income from the mine would go to Mongolia.
