The Victor Diamond Mine is the first Canadian diamond mine located in Ontario, and De Beers' second diamond mine in Canada (after the Snap Lake Diamond Mine).
 It is located in the Northern Ontario Ring of Fire, in the James Bay Lowlands 90 km west of Attawapiskat in the remote northern part of the province.
 In June 2005, the Attawapiskat First Nation voted in favour (85.5%) of ratifying the Impact Benefit Agreement (IBA).
 Construction of the mine began in February 2006 which created 3200 positions; mining and operations will create around 400 permanent positions.
 The Victor Mine is an open-pit mine, with a processing plant, workshops, and an airstrip located on site.
 By 2013-2014 royalties collected from De Beers Victor Diamond Mine amounted to $226.
 At that time De Beers was continuing to pay off its "$1 billion investment to build the mine and from now until it closes, the company expects to pay tens of millions of dollars in royalties."
The Dry Fork mine is a coal mine located 8 miles north of Gillette, Wyoming in the United States in the coal-rich Powder River Basin.
 The mine is an open pit mine that utilizes truck and shovel mining method to mine a low-sulfur, sub-bituminous coal that is used for domestic energy generation and shipped to customers via railroad.
 In 2011, the mine is expected to begin supplying coal to the newly constructed Dry Fork power station that has been constructed adjacent to the mine.
 The mine is currently owned and operated by Western Fuels Association.
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.
Copperfields Mine, originally known as Temagami Mine, is an abandoned copper and silver mine on Temagami Island in Lake Temagami, Ontario, Canada.
 The mine opened in 1955 and comprises both underground and surface workings within a sulfide ore body.
 Situated in Phyllis Township, the mine produced 34,000,000 dollars Canadian with 80 million pounds of copper, 230,028 ounces of silver and 13,271 ounces of gold.
 It was considered to be the largest deposit of nearly pure chalcopyrite ever discovered in Canada.
 A mill was not initially needed because the ore was 28% copper.
 The mine closed in 1972 and is now flooded by water.
 Ruins of the Copperfields mill are present as foundations.
 It is possible to find mineral specimens in the spoil heaps of the old mine, such as chalcopyrite, pyrite, bornite, malachite, dolomite, hessite, merenskyite, millerite, palladium, quartz and others.
 The Lake Temagami Access Road was created to ship ore from the mine site.
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 Husab Mine, also known as the Husab Uranium Project, is a uranium mine under development near the town of Swakopmund in the Erongo region of western-central Namibia.
 The mine is located approximately 60 km from Walvis Bay.
 The Husab Mine is expected to be the second largest uranium mine in the world after the McArthur River uranium mine in northern Saskatchewan, Canada and the largest open-pit mine on the African continent.
 The Husab Mine is to start production in early December 2015 after completion of the sulfuric acid leaching plant.
Temagami Island, formerly spelt as Timagami Island, is an island in Lake Temagami in Northeastern Ontario, Canada.
 It is the largest island within the lake, with Bear Island coming second.
 The island has many hiking trails that lead into the old-growth forest that is a mix of large white and red pine trees.
 Temagami Mine, later known as Copperfields Mine, was a copper mine that opened on Temagami Island in 1954.
 It was considered to be the largest deposit of nearly pure chalcopyrite ever discovered in Canada.
 The mine closed in 1972.
The Raspadskaya Coal Mine is a coal mine located in Mezhdurechensk, Kemerovo Oblast, Russia.
 It is the largest coal and the largest underground mine in Russia.
 The mine was opened in 1973 and its construction was completed in 1977.
 In addition to the main underground mine, the mining complex also includes MUK-96 underground mine, Raspadskaya Koksovaya underground mine, and Razrez Raspadsky open-pit mine, as also the Raspadskaya preparation plant.
Leckie Mine, also known as Penrose Mine and Little Dan Mine, is an abandoned gold producing underground mine in Northeastern Ontario, Canada, located on the eastern shore of Arsenic Lake 4 km north of the town of Temagami.
 It is entirely owned by Temagami Gold Inc.
 An estimated 483,500 tonnes of ore remain in the mine, which could contain 102,720 ounces of gold.
Big Dan Mine is an abandoned underground mine in Northeastern Ontario, Canada.
 It is located about 1 km southwest of Net Lake and just west of the Ontario Northland Railway in east-central Strathy Township.
 It is named after Dan O'Connor, who first claimed the site in the 1890s.
