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.
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 Gahcho Kué Diamond Mine is located on the Canadian tundra in the Northwest Territories.
 It is situated at Kennady Lake ( ), in the Akaitcho Treaty 8 Territory AK claim block, which is 85 km southeast of the Snap Lake Diamond Mine and approximately 280 km east northeast of Yellowknife.
 The site is served by Gahcho Kue Aerodrome, which has both an ice runway in winter and a year-round gravel runway, and a spur of the Tibbitt to Contwoyto Winter Road from Lupin Mine.
 the main camp is at , north of the ice strip, with a smaller site at , south of the runway.
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 Khewra Salt Mine (or Mayo Salt Mine) is located in Khewra, north of Pind Dadan Khan, an administrative subdivision of Jhelum District, Punjab Region, Pakistan, which rises from the Indo-Gangetic Plain.
 It is Pakistan's largest and oldest salt mine and the world's second largest.
 It is a major tourist attraction, drawing up to 250,000 visitors a year.
 Its history dates back to its discovery by Alexander's troops in 320 BC, but it started trading in the Mughal era.
 The main tunnel at ground level was developed by Dr. H. Warth, a mining engineer, in 1872 during British rule.
 After independence, the Pakistan Mineral Development Corporation took over the mine, which still remains the largest source of salt in the country, producing more than 350,000 tons per annum of about 99% pure halite.
 Estimates of the reserves of salt in the mine vary from 82 million tons to 600 million tons.
Tundra Mine/Salamita Mine Aerodrome (TC LID: CTM7) is a registered aerodrome that served the Tundra and Salamita Mines in the Northwest Territories, Canada.
The National Mine Map Repository (NMMR) is part of the United States Department of the Interior (DOI), Office of Surface Mining Reclamation and Enforcement (OSMRE or OSM).
 The NMMR resides in the Pittsburgh suburb of Green Tree, Pennsylvania, and collects and maintains mine map information and images for the entire country, including data and maps of coal mines in the anthracite coal region of northeastern Pennsylvania.
 The Green Tree facility provides and stores, digitally and in microfilm (aperture cards), over 182,000 maps of abandoned mines.
 This repository contains maps of mine workings from the 1790s to the present day.
 It serves as a point of reference for mine maps and other information for both surface and underground mines throughout the United States.
 It also serves as a location to retrieve mine maps in an emergency.
 The NMMR provides services ranging from retrieving mine related data for economic analysis to assessing the potential risk associated with underground mining.
 Through analysis of mine maps and related information, the repository assists private and public sectors in industrial and commercial development, highway construction, and the preservation of public health, safety, and welfare.
 In addition, they collect, reproduce, and maintain a national inventory of mine maps and supporting documentation for private and public interests.
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.
Kayelekera uranium mine is an open cast uranium mine 52 kilometers west of the regional administrative and commercial centre Karonga in Malawi, Africa and is the country's largest mine.
 Kayelekera is owned 100% by Paladin (Africa) Limited (PAL), an 85% subsidiary of Australian and Canadian listed Paladin Energy and in July 2009, Paladin issued 15% of the equity in Paladin (Africa) Ltd to the Government of Malawi under the terms of the Mining Development Agreement signed between PAL and the Government in February 2007.
 The mine was officially opened on 17 April 2009 by the then Malawian president Bingu wa Mutharika.
 As of 2014, the mine is in care and maintenance mode owing to a depressed uranium market.
 While in production, the mine exported containers of uranium oxide via the port of Walvis Bay.
 The mine has not been profitable for its operators and has met opposition from organisations and individuals concerned about the mine's tax concessions, operation, adherence to law and regulation and its potential impacts on human and environmental safety.
The Sukari mine or Alsukari mine (Arabic: السكري "Al-Sukkari", Egyptian pronunciation: "El-Sokkari") is a Gold Mine located in the Nubian Desert/Eastern Desert near the Red Sea in Egypt in the south-east of the country in the Red Sea Governorate, 30 km south of Marsa Alam.
 It is exploited jointly by the Egyptian Ministry of Mineral Resources and Centamin.
 It is Egypt's first modern gold mine, an industry considered to have scope for expansion in the country.
 Egypt was known in the ancient world as being a source of gold, and one of the earliest available maps shows a gold mine at this location.
