The Highland Valley Copper mine is the largest open-pit copper mine in Canada, located near Logan Lake, British Columbia. It is an amalgamation of three historic mining operations: Bethlehem (later Valley Copper), Lornex and Highmont. [1]
The earliest roots of the Bethlehem mining operations began when the Jersey zone was staked and bonded to a French syndicate c. 1886 – c. 1887. This claim changed hands several times until finally in October 1954 when the Huestis-Reynolds-McLallen Syndicate sponsored a prospective examination covering 100 claims including Jersey and surrounding zones. [2]
Copper was known to occur in the Cascade Mountains near Princeton as the productive mines of Allenby in 1914 had shown. On the strength of this, prospectors searched for other deposits in the region. These they found north of Merritt and east of Ashcroft at Logan Lake at the Jersey zone.
In February 1960, Bethlehem Copper Corporation made an agreement with the Japanese group Sumitomo for US$5.5 million to bring the property into production. Construction began in July 1961. At the time, Jersey and East Jersey were identified as zones containing suitable ore for production, and an assessment was completed of the area between the two zones. It was found that this middle area did not have suitable deposits to favour commercial operation and the Jersey and East Jersey zones were mined separately. This operation of two mines in close proximity by the same company led to a case brought before the Supreme Court of Canada on what constituted a mine for tax purposes. [3]
Production of the East Jersey pit began on November 28, 1962, and continued until February 17, 1965, when a rock slide forced the Company to end the pit's life early. Production of the Jersey pit began quickly after.
The Jersey pit was given an extension in 1977, extending its life another 5 years. Two minor additional pits were also operated for brief periods during this time: Huestis from 1970 to 1976 and Iona from 1976 to 1979. [2]
On the south side of the valley the Lornex mine began mining in 1972. [4]
In 1981 Cominco, who already owned the claim to the Valley Copper deposit located west of Bethlehem, purchased Bethlehem Copper to consolidate the nearby operations. Mining of the original Bethlehem Copper pits ceased in 1982. The Bethlehem concentrator continued to operate on ore from the Valley Copper deposit until June 1989.
Production on the Valley Copper mine, now the largest mine and most noticeable feature, began in January 1983. [5] For fifty years the ore was dug using shovels and open pit methods. A very large pit ensued--half a mile deep and two miles in diameter.
Highland Valley Copper was created in mid-1986 when the Highland Valley mining operations of Lornex Mining Corporation Ltd. and Cominco Ltd. were combined into a new single entity, structured as a partnership.
The Highmont mill on the south side of the valley was acquired in 1988 when Highmont Mining Company joined the partnership. This mill had been closed down in 1984 when the Highmont deposit became uneconomical.
A large tailing pond is maintained to support these operations (48.5 million tonnes of tailings pumped in 2003), with two containment embankments to retain the tailings from the environment. [6] In April 2017 freezing pipes caused 850 cubic meters of process water to spill. The spill was contained on site and returned to the tailing pond. [7] Trojan Pond, a previous tailing pool used in the operation, began to be reclaimed in 1990 [8] and is now a self-sustaining ecosystem and used for sport fishing. [9]
Copper and molybdenum mineral concentrates, which include trace amounts of silver and gold, are sent via truck to nearby rail facilities in Ashcroft where the ore is carried to the Port of Vancouver and to international destinations (primarily Japan and China for copper and steel production).[ citation needed ] The mine employed approximately 1300 persons in 2011.

Chuquicamata is the largest open pit copper mine in terms of excavated volume in the world. It is located in the north of Chile, just outside Calama, at 2,850 m (9,350 ft) above sea level. It is 215 km (134 mi) northeast of Antofagasta and 1,240 km (770 mi) north of the capital, Santiago. Flotation and smelting facilities were installed in 1952, and expansion of the refining facilities in 1968 made 500,000 tons annual copper production possible in the late 1970s. Previously part of Anaconda Copper, the mine is now owned and operated by Codelco, a Chilean state enterprise, since the Chilean nationalization of copper in the late 1960s and early 1970s. Its depth of 850 metres (2,790 ft) makes it the second deepest open-pit mine in the world, after Bingham Canyon Mine in Utah, United States.

The Pine Point Mine is located on the south shore of Great Slave Lake between Hay River to the west and Fort Resolution to the east, in the Northwest Territories of Canada. It produced lead and zinc ores from a Mississippi Valley Type deposit between 1964 and 1988. Most of the mining was done by open-pit methods. The town of Pine Point was built by the mining company, Cominco, and when the mine closed the town was abandoned and demolished.
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).
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 man-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.

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.
Copper mining in the United States has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2017 the United States 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.
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 Climax mine, located in Climax, Colorado, United States, is a major molybdenum mine in Lake and Summit counties, Colorado. Shipments from the mine began in 1915. At its highest output, the Climax mine was the largest molybdenum mine in the world, and for many years it supplied three-fourths of the world's supply of molybdenum.
Phoenix Mine was an open pit and underground mining operation in city of Phoenix in the Boundary Country region of British Columbia, Canada that operated in the early and mid 20th century, run by the Granby Consolidated Mining, Smelting and Power Company. It was discovered in 1891, but was a lower grade copper deposit than the Rossland and Slocan deposits. The low grade and the nearest railroad being 75 miles (121 km) resulted in the Phoenix receiving less attention.
Granby Consolidated Mining, Smelting and Power Co. was established by charter to operate in the Boundary region of southern British Columbia. Primarily involved in the mining and smelting of copper, the conglomerate became a publicly traded company. The various corporate operating names within the former group mostly specified the Granby identity.
