The Yellow Dog Plains is an area north and west of Marquette, Michigan, in the Upper Peninsula of Michigan, United States. The Yellow Dog River flows through it, as does the Salmon Trout River. The Salmon Trout River is unique in that it has a breeding population of coasters, a potamodromous form of brook trout. Coasters are virtually extinct from their native range on the south coast of Lake Superior, except for the Salmon Trout River. The Yellow Dog Plains is a remote and virtually untouched wilderness, aside from large scale logging operations. There are extensive forests of Eastern white pine, with reports of some of the trees in the Yellow Dog Plains reaching heights of 31 meters.
The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains. The mine is the largest human-made excavation, and deepest open-pit mine in the world, which is considered to have produced more copper than any other mine in history – more than 19,000,000 short tons. The mine is owned by Rio Tinto Group, a British-Australian multinational corporation. The copper operations at Bingham Canyon Mine are managed through Kennecott Utah Copper Corporation which operates the mine, a concentrator plant, a smelter, and a refinery. The mine has been in production since 1906, and has resulted in the creation of a pit over 0.75 miles (1,210 m) deep, 2.5 miles (4 km) wide, and covering 1,900 acres. It was designated a National Historic Landmark in 1966 under the name Bingham Canyon Open Pit Copper Mine. The mine experienced a massive landslide in April 2013 and a smaller slide in September 2013.

Comet is a ghost town located approximately twenty miles south-southwest of Helena, Montana, United States. It is reached by following High Ore Road north from Interstate 15. The remains of the town cover about thirty-five acres and consist of an ore hopper, a large ore processing building, several other company buildings, and numerous houses and other private structures. High Ore Creek runs through the center of the property and separates the mine buildings from the town proper. The town is abandoned except for a single active residence; although it sits on private grazing land, it is open to public access.
Creighton Mine is an underground nickel, copper, and platinum-group elements (PGE) mine. It is presently owned and operated by Vale Limited in the city of Greater Sudbury, Ontario, Canada. Open pit mining began in 1901, and underground mining began in 1906. The mine is situated in the Sudbury Igneous Complex (SIC) in its South Range geologic unit. The mine is the source of many excavation-related seismic events, such as earthquakes and rock burst events. It is home to SNOLAB, and is currently the deepest nickel mine in Canada. Expansion projects to deepen the Creighton Mine are currently underway.
In the United States, copper mining has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2017, the US produced 1.27 million metric tonnes of copper, worth $8 billion, making it the world's fourth largest copper producer, after Chile, China, and Peru. Copper was produced from 23 mines in the US. Top copper producing states in 2014 were Arizona, Utah, New Mexico, Nevada, and Montana. Minor production also came from Idaho, and Missouri. As of 2014, the US had 45 million tonnes of known remaining reserves of copper, the fifth largest known copper reserves in the world, after Chile, Australia, Peru, and Mexico.
In Michigan, copper mining became an important industry in the 19th and early 20th centuries. Its rise marked the start of copper mining as a major industry in the United States.
Lundin Mining Corporation is a Canadian company that owns and operates mines in Sweden, United States, Chile, Portugal and Brazil that produce base metals such as copper, zinc, and nickel. Headquartered in Toronto, the company was founded by Adolf Lundin and operated by Lukas Lundin. While it was incorporated to pursue an interest in a diamond mine in Brazil, the company re-structured and raised funds to develop the Storliden mine in Sweden. It purchased the Swedish Zinkgruvan Mine from Rio Tinto and then merged with Arcon International Resources for its Galmoy Mine in Ireland and with Eurozinc for its Neves-Corvo mine in Portugal. The company subsequently purchased and operated the Eagle mine, Candelaria mine, and Chapada mine.
The mineral industry of Russia is one of the world's leading mineral industries and accounts for a large percentage of the Commonwealth of Independent States' production of a range of mineral products, including metals, industrial minerals, and mineral fuels. In 2005, Russia ranked among the leading world producers or was a significant producer of a vast range of mineral commodities, including aluminum, arsenic, cement, copper, magnesium compounds and metals, nitrogen, palladium, silicon, nickel and vanadium.
County Road 595 was a proposed primary county road in Marquette County in the US state of Michigan. The road would have provided access from the northern part of the county, near the Eagle Mine in Michigamme Township, to US Highway 41 (US 41) and M-28 in Humboldt Township. The approximately 21.5-mile-long (34.6 km) road would have been used primarily for commercial truck traffic hauling rock from the Eagle Mine to a processing facility south of US 41/M-28 in Humboldt Township. At present, such traffic has to use existing county roads which involves passing through the cities of Marquette, Negaunee, and Ishpeming. The northern end would have been northeast of the mine in Champion Township at an intersection with the Triple A Road.
A nickel mine is a mine that produces nickel. Some mines produce nickel primarily, while some mines produce nickel as a side-product of some other metal that has a higher concentration in the ore.
The Mohawk Mining Company was a major copper mining company, based in the Keweenaw Peninsula of Michigan, that was established in November 1898 and lasted until 1932. The company, between 1906 and 1932, paid out more than $15 million in shareholder dividends. The Mine is best known for the large amounts of mohawkite that were found on the property. The Mohawk mine operated until 1932; in 1934 it was purchased by the Copper Range Company.
Keweenawite is a discredited mineral species. It was described as an arsenide of copper, nickel, and cobalt containing 39% to 54% copper, 9.7% to 20% nickel, and 0.9% cobalt. Keweenawite was discovered in July 1901, in the Mohawk Mine, Keweenaw County, Michigan. George A Koenig analyzed and named the copper ore.
The Flambeau Mine was an open pit mine of a copper-gold deposit near the Flambeau River south of Ladysmith, Wisconsin, United States. It was mined by a subsidiary of Kennecott Minerals between 1993 and 1997, and returned to a fairly natural state after. As of 2022, it was "the only example of a metallic mine that was permitted, constructed, operated, and reclaimed under [Wisconsin's] existing regulatory framework."
Twin Metals LLC is seeking approval to create and operate a copper sulfide mine near Ely, Minnesota, on Superior National Forest land. There has been significant opposition to the proposed mine, most notably because of its proximity to the Boundary Waters Canoe Area Wilderness, location within a watershed that drains into the BWCA, and the air, water, light and noise pollution and traffic effects of converting a forested area bordering the BWCA into a substantial industrial mining facility. Twin Metals is a subsidiary of the Chilean conglomerate Antofagasta, which is controlled by billionaire Andrónico Luksic. The original lease is a 1966 lease to the International Nickel Corporation.
The Back Forty Mine is a proposed open-pit metallic sulfide mine targeting gold and zinc deposits in Menominee County in the South Central part of Michigan's Upper Peninsula next to the Menominee River.
