Little Cornwallis Island is one of the Queen Elizabeth Islands in the Canadian Arctic islands in Nunavut, Canada. It is located at 75°30'N 96°30'W, between Cornwallis Island and Bathurst Island in McDougall Sound, and measures 412 km2 (159 sq mi). It is uninhabited.
Pine Point is an abandoned locality that formerly held town status near the south shore of Great Slave Lake between the towns of Hay River and Fort Resolution in the Northwest Territories of Canada. It was built to serve the work force at the Pine Point Mine, an open-pit mine that produced lead and zinc ores. The town's population peaked at 1,915 in 1976, but was abandoned and deconstructed in 1988 after the mine closed in 1987.
The Southeast Missouri Lead District, commonly called the Lead Belt, is a lead mining district in the southeastern part of Missouri. Counties in the Lead Belt include Saint Francois, Crawford, Dent, Iron, Madison, Reynolds, and Washington. This mining district is the most important and critical lead producer in the United States.
The Sullivan Mine is a now-closed conventional–mechanized underground mine located in Kimberley, British Columbia, Canada. The ore body is a complex, sediment-hosted, sedimentary exhalative deposit consisting primarily of zinc, lead, and iron sulphides. Lead, zinc, silver and tin were the economic metals produced. The deposit lies within the lower part of the Purcell Supergroup and mineralization occurred about 1470 million years ago during the late Precambrian (Mesoproterozoic).
Neil Campbell FRSC was a Canadian geologist, and is a notable within the Canadian Mining Hall of Fame.
Heath Steele Mines, situated 60 km (37 mi) northwest of Newcastle, New Brunswick, Canada, at the headwaters of the Tomogonops and Little Rivers, was a large and productive copper, lead, and zinc mine which operated from 1956 to 1999. The mine was an economic cornerstone of Miramichi communities throughout this period.
Silver mining in the United States began on a major scale with the discovery of the Comstock Lode in Nevada in 1858. The industry suffered greatly from the demonetization of silver in 1873 by the Coinage Act of 1873, known pejoratively as the "Crime of 73", but silver mining continues today.
Carbonate-hosted lead-zinc ore deposits are important and highly valuable concentrations of lead and zinc sulfide ores hosted within carbonate formations and which share a common genetic origin.
The Broken Hill Ore Deposit is located underneath Broken Hill in western New South Wales, Australia, and is the namesake for the town. It is arguably the world's richest and largest zinc-lead ore deposit.
The Red Dog mine is a large zinc and lead mine in a remote region of Alaska, about 80 miles (130 km) north of Kotzebue, which is owned and operated by the Canadian mining company Teck Resources. It is located within the boundaries of the Red Dog Mine census-designated place in the Northwest Arctic Borough of the U.S. state of Alaska.
The Admiralty mining district is a mining area in the U.S. state of Alaska which consists of Admiralty Island. Silver and base metals are mined, with gold recovered as a by-product.
Mining is the biggest contributor to Namibia's economy in terms of revenue. It accounts for 25% of the country's income. Its contribution to the gross domestic product is also very important and makes it one of the largest economic sectors of the country. Namibia produces diamonds, uranium, copper, magnesium, zinc, silver, gold, lead, semi-precious stones and industrial minerals. The majority of revenue comes from diamond mining. In 2014, Namibia was the fourth-largest exporter of non-fuel minerals in Africa.
Polaris zinc mine was a former underground mine on Little Cornwallis Island in the Canadian territory of Nunavut. The zinc mine was located 1,120 km (700 mi) north of the Arctic Circle, and 96 km (60 mi) north of the community of Resolute. It closed in July 2002 following more than twenty years of zinc production.
Thor Lake is a deposit of rare metals located in the Blachford Lake intrusive complex. It is situated 5 km north of the Hearne Channel of Great Slave Lake, Northwest Territories, Canada, approximately 100 kilometers east-southeast of the capital city of Yellowknife. Geologically located on the Canadian Shield it is mostly composed of peralkaline syenite. The Blatchford Lake complex was created in the early Proterozoic, 2.14 Ga ago. The deposit is divided in several sub-structures. In a small zone at the northern edge of the syenite, the T-Zone, minerals like bastnäsite, phenakite and xenotime can be found.
Oil and gas dominate the extraction industries of the Republic of the Congo, also referred to as Congo-Brazzaville. The petroleum industry accounted for 89% of the country’s exports in 2010. Among African crude oil producers in 2010, The Congo ranked seventh. Nearly all of the country's hydrocarbons were produced off-shore. The minerals sector is administered by the Department of Mines and Geology. Presently no major mining activities are underway, although there are some small-scale domestic operations. However, the country does have numerous large-scale undeveloped resources. The country has recently attracted a strong influx of international companies seeking to tap into the vast mineral wealth.
Mining in North Korea is important to the country's economy. North Korea is naturally abundant in metals such as magnesite, zinc, tungsten, and iron; with magnesite resources of 6 billion tonnes, particularly in the North and South Hamgyong Province and Chagang Province. However, often these cannot be mined due to the acute shortage of electricity in the country, as well as the lack of proper tools to mine these materials and an antiquated industrial base. Coal, iron ore, limestone, and magnesite deposits are larger than other mineral commodities. Mining joint ventures with other countries include China, Canada, Egypt, and South Korea.
The Shady Dolomite is a geologic formation composed of marine sedimentary rocks of early Cambrian age. It outcrops along the eastern margin of the Blue Ridge province in the southeastern United States and can be found in outcrops in the states of Alabama, Georgia, Tennessee, North Carolina, and Virginia. It can also be found in the subsurface of Kentucky, Ohio, and West Virginia. The Shady is predominantly composed of dolomite and limestone with lesser amounts of mudrock. It contains fossils of trilobites, archaeocyathids, algae, brachiopods, and echinoderms, along with the enigmatic fossil Salterella. The Shady Dolomite was first described by Arthur Keith in 1903 and was named for exposures in the Shady Valley of Johnson County in the state of Tennessee. Near Austinville, Virginia, the Shady hosts ore deposits that have been mined extensively for lead and zinc ore.
Zinc mining in the United States produced 780,000 tonnes of zinc in 2019, making it the world's fourth-largest zinc producer, after China, Australia, and Peru. Most US zinc came from the Red Dog mine in Alaska. The industry employed about 2,500 in mining and milling, and 250 in smelting.
The mining industry of Yemen is at present dominated by fossil mineral of petroleum and liquefied natural gas (LNG), and to a limited extent by extraction of dimension stone, gypsum, and refined petroleum. Reserves of metals like cobalt, copper, gold, iron ore, nickel, niobium, platinum-group metals, silver, tantalum, and zinc are awaiting exploration. Industrial minerals with identified reserves include black sands with ilmenite, monazite, rutile, and zirconium, celestine, clays, dimension stone, dolomite, feldspar, fluorite, gypsum, limestone, magnesite, perlite, pure limestone, quartz, salt, sandstone, scoria, talc, and zeolites; some of these are under exploitation.
The Teck Cominco smelter, also known as the Teck Cominco Lead-Zinc Smelter, Cominco Smelter, and Trail smelter located in Trail, British Columbia, Canada, is the largest integrated lead-zinc smelter of its kind in the world. It is situated approximately 10 miles (16 km) north of the border between British Columbia, Canada and Washington, in the United States, on the Columbia River. It is owned and operated by Vancouver, British Columbia-based Teck Cominco Metals Ltd—renamed Teck Resources.
