The Thompson-Lundmark Mine was a gold producer in the periods 1941–1943 and 1947–1949, near Yellowknife, Northwest Territories. Gold was discovered here in 1938 by Fred W. Thompson and Roy Lundmark, who staked 46 claims which were incorporated into the mine. Underground and shaft work began in 1939. The mine processed 133,989 tons of ore to produce 70,339 troy ounces (2,187.8 kg) of gold and 13,782 troy ounces (428.7 kg) of silver. The abandoned site was destroyed by forest fires during 1998.

The Giant Mine was a gold mine located on the Ingraham Trail, 5 km (3.1 mi) north of Yellowknife, Northwest Territories. Giant Mine was within the Kam Group, a part of the Yellowknife greenstone belt. Gold was discovered on the property and mineral claims staked in 1935 by Johnny Baker, but the true extent of the gold deposits was not known until 1944, when a massive gold-bearing shear zone was uncovered beneath the drift-filled Baker Creek Valley.
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 5,000,000 ozt (160,000 kg) of gold from 12,195,585 tons of ore processed. The mine was over 6,000 ft (1,800 m) deep.
The Rayrock Mine was a uranium producing venture in the Northwest Territories, Canada. It is located on the south side of Maryleer Lake and the north shore of Fault Lake, 169 kilometers northwest of Yellowknife and 74 kilometres northwest of Rae. Radioactive deposits were originally staked in 1948 and then restaked in 1950. American Yellowknife Mines Limited explored the site with detailed Geiger surveys and extensive trenching in the early 1950s. In 1954 exploration work included over 10,000 feet (3,000 m) of surface diamond drilling, and the company was reorganized as Rayrock Mines Limited.
The Ptarmigan and Tom Mine were gold producers located in the Northwest Territories, Canada at Yellowknife. The property was staked by prospectors in 1936 and acquired by Cominco in 1938. The mine first produced between 1941 and 1942 but closed due to wartime restrictions. The old property was demolished in 1969–1970. A new company, Treminco Resources Limited, reopened the workings in 1985 and production from the Tom portal began in 1986 with material being trucked to Giant Mine. The old Ptarmigan mine shaft was dewatered and production began in 1987. A new mill was built at the property and was operational in July 1989. Low gold prices forced the company to close the mines in 1997. Total gold production has been approximately 120,000 troy ounces.
Negus Mine was a gold producer at Yellowknife, Northwest Territories, Canada, from 1939 to 1952. It produced 255,807 troy ounces (7,956.5 kg) of gold from 490,808 tons of ore milled. The underground workings were acquired by adjacent Con Mine in 1953 and were used for ventilation purposes until Con Mine closed in 2003.
The Burwash Mine was a small gold property discovered in the fall of 1934 by Johnny Baker and Hugh Muir at Yellowknife Bay, Northwest Territories. The town of Yellowknife did not exist yet at that point, but the discovery of gold at Burwash was the catalyst that brought more gold prospectors into the region in 1935 and 1936. A short shaft was sunk in 1935–1936 at Burwash, and in the summer of 1935 a 16-ton bulk sample of ore was shipped to Trail, British Columbia for processing, yielding 200 troy ounces (6.2 kg) of gold. The mine did not become a substantial producer and it is believed the gold vein was mined out.
The Discovery Mine was a gold mine 84 kilometers northeast of Yellowknife, Northwest Territories that operated between 1950 and 1969. Gold was discovered here by Alfred Giauque in 1944. A complete townsite, on Giauque Lake, was established by the company to house workers and their families. The mine produced one million troy ounces (31,000 kg) of gold from one million tons of ore. The abandoned townsite, not accessible by road, was demolished in 2005.
The Camlaren Mine was a small gold mine 80 km (50 mi) north-east of Yellowknife, Northwest Territories, Canada at Gordon Lake. It consists of a property totaling about 981 hectares. The two claims that make up the property were staked in 1936 by prospectors Don Cameron and the Mclaren brothers and developed with two shafts during 1937–1938. The name "Camlaren" is a portmanteau of Cameron and McLaren. Conditions attributed to World War II halted development at Camlaren in 1939.
The Beaulieu Mine was a post-World War II gold mining operation near Yellowknife, Northwest Territories. It entered production in October 1947 but by the end of November only 7 ounces of rough gold were recovered. Additional gold was recovered during 1948, but the mine recovered only 30 troy ounces (930 g) of fine gold altogether. The operation folded in chaos and bankruptcy.
The Ruth Mine was a small gold producer about 65 kilometres (40 mi) east of Yellowknife, Northwest Territories. It operated briefly during 1942 and resumed operations in 1959, extracting to date 550 troy ounces of gold.
The Tundra Mine is a gold mine that operated in the Northwest Territories, of Canada between 1962 and 1968, producing 104,476 troy ounces (3,249.6 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 (5,595.7 kg) of gold from the milling of 238,177 tons of ore. The area is now owned by Seabridge Gold.
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.
Gold mining in Alaska, a state of the United States, has been a major industry and impetus for exploration and settlement since a few years after the United States acquired the territory in 1867 from the Russian Empire. Russian explorers discovered placer gold in the Kenai River in 1848, but no gold was produced. Gold mining started in 1870 from placers southeast of Juneau, Alaska.
Gold mining in Nevada, a state of the United States, is a major industry, and one of the largest sources of gold in the world. In 2018 Nevada produced 5,581,160 troy ounces, representing 78% of US gold and 5.0% of the world's production. Total gold production recorded from Nevada from 1835 to 2017 totals 205,931,000 troy ounces (6,405.2 t), worth US$322.6 billion at 2020 values. Much of Nevada's gold production comes from large open pit mining using heap leaching recovery.
The Mining industry of Ghana accounts for 5% of the country's GDP and minerals make up 37% of total exports. Gold contributes over 90% of the total mineral exports. Thus, the main focus of Ghana's mining and minerals development industry remains focused on gold. Ghana is Africa's largest gold producer, producing 80.5 t in 2008. Ghana is also a major producer of bauxite, manganese and diamonds. Ghana has 20 large-scale mining companies producing gold, diamonds, bauxite and manganese; over 300 registered small scale mining groups; and 90 mine support service companies.Other mineral commodities produced in the country are natural gas, petroleum, salt, and silver.
Platinum as an investment is often compared in financial history to gold and silver, which were both known to be used as money in ancient civilizations. Experts posit that platinum is about 15–20 times scarcer than gold and approximately 60–100 times scarcer than silver, on the basis of annual mine production. Since 2014, platinum prices have fallen lower than gold. Approximately 75% of global platinum is mined in South Africa.
The Telfer Mine is a gold, copper and silver mine located at Telfer on the land of the Martu people, in the Great Sandy Desert of Western Australia. It is owned by Newcrest Mining, the largest gold producer listed on the Australian Securities Exchange.
The Canadian Malartic Corporation is a mining company that operates the Malartic mine near Malartic, Quebec. Prior to 2014 the company was a public company named Osisko Mining Corporation with shares listed on the Toronto Stock Exchange and New York Stock Exchange. In 2014, Osisko Mining was subject to a hostile takeover bid by Goldcorp but an alternative bid by white knights Yamana Gold and Agnico Eagle Mines Limited was accepted that, in addition to offering a higher price, created the spin-off Osisko Gold Royalties and turned Osisko Mining Corporation into the subsidiary company Canadian Malartic Corporation jointly owned by Yamana Gold and Agnico Eagle. From its founding in 1982 until 2006, Osisko Mining bought and sold mineral exploration rights in Quebec, conducting exploration work. The company acquired an interest in the Canadian Malartic property in 2004 and after promising feasibility studies the mine was constructed with commercial production achieved in May 2011.is a Canadian company engaged in the exploration and development of several mineral properties in Quebec.
