Overview
Noranda Mines was a Canadian mining and metals company founded in 1922 to develop the Horne deposit near Rouyn-Noranda, Quebec. The company began producing copper on 17 December 1927. The original Horne mine was expected to have a short life, but the discovery of the much larger Giant H orebody transformed it into the central asset of a substantial Canadian mining enterprise. Horne remained the backbone of Noranda's operations until its reserves were exhausted in 1976. From the 1930s onward, Noranda pursued an unusually broad diversification strategy. It acquired or developed interests in forestry, oil, manufacturing, automotive-related businesses, aluminum, zinc, gold, copper, and mineral processing. In 1931 it opened the Canadian Copper Refiners, or CCR, refinery at Montréal-Est to process copper from the Horne smelter. Its first major international mining property came in 1938 through the acquisition of the Empresa Minera de Nicaragua gold mine. The company later acquired a significant interest in Kerr Addison Gold Mines and developed or invested in numerous Canadian base-metal operations. Noranda expanded its metals-processing platform through the Gaspé Copper Mines, Canadian Electrolytic Zinc, Brunswick Mining and Smelting, aluminum facilities in the United States, and recycling operations. It also developed international exposure in Chile, Nicaragua, Peru, Jamaica, and other markets. Its 34 percent interest in the Antamina copper-zinc mine in Peru, which began operating in 2001, was among the most important later additions to the portfolio. By 2005, Noranda reported operations in 18 countries. The company underwent a strategic narrowing in the late 1990s. After years of diversification outside mining and metals, it announced in 1997 that it would sell businesses unrelated to its core resources activities. The transition was substantially completed in 1998, when forestry and oil and gas interests were removed from the group. Noranda also developed a significant recycling business, including electronic-scrap processing and battery recycling, alongside its traditional mining, smelting, refining, and aluminum activities. Noranda's corporate identity changed in 1984, when Noranda Mines changed its name to Noranda Inc. to reflect the breadth of its businesses. Its ownership and strategic direction were also influenced by major Canadian investment institutions. In 1981, Brascan and the Caisse de dépôt et placement du Québec made a major investment that gave them effective control. Noranda had acquired 19.9 percent of Falconbridge in 1988 and increased that holding to 58.4 percent by 2002. In 2004, China Minmetals negotiated a proposed acquisition of Noranda valued at C$6.7 billion. The proposed transaction generated public and governmental debate about foreign ownership of Canadian natural-resource companies and prompted a review of Canada's foreign-investment policy. The proposal did not proceed. Instead, Noranda pursued a combination with Falconbridge. The merger was completed in June 2005, although the resulting company operated under the Falconbridge name, effectively ending Noranda as a major independent mining brand. Falconbridge was acquired by Xstrata in 2006, and Xstrata was later fully acquired by Glencore in 2013. The Noranda name survived in certain successor or related businesses, including Noranda Aluminum and the Noranda Income Fund, but the original Noranda Mines enterprise ceased to exist as an independent company. Noranda Mines was a Canadian mining and metallurgy company established in 1922 to develop the Horne mineral deposit near Rouyn-Noranda, Quebec. Under the leadership of James Young Murdoch, the company transformed a local copper prospect into the foundation of a broad industrial group. Copper extraction began at the Horne mine in December 1927. Although the original deposit was expected to support only a short operating life, the discovery of the much larger Giant H orebody extended the mine's importance for decades. The Horne operation ultimately remained central to Noranda until its reserves were exhausted in 1976. From the 1930s onward, Noranda expanded beyond a single mine. It opened the Canadian Copper Refiners refinery in Montréal-Est in 1931 to process copper from the Horne smelter, and acquired or developed interests in forestry, oil, manufacturing, automotive activities, zinc, aluminum, potash, recycling and other industrial businesses. Its first international mining property was acquired in Nicaragua in 1938. The company later established or acquired significant interests in Canadian operations including Gaspé Copper Mines, Canadian Electrolytic Zinc and Brunswick Mining and Smelting. It also invested in Chile, the United States, Peru and Jamaica, eventually operating across 18 countries. Noranda's growth was marked by a shift from a primarily Canadian copper producer to a diversified mining and metals group. During the 1970s it expanded into aluminum through a smelter in Missouri and into oil through Canadian Hunter. In the 1980s it entered electronics-scrap recycling and changed its legal name from Noranda Mines to Noranda Inc. in 1984, reflecting its broader portfolio. During the 1990s, the company increasingly concentrated on mining, metals processing and recycling, eventually announcing a plan to divest businesses unrelated to those fields. The forestry and oil and gas businesses were removed during the following year. Noranda also built a strategic position in rival miner Falconbridge. It acquired a 19.9 percent interest in Falconbridge in 1988 and increased that holding to 58.4 percent by 2002. In 2004, Noranda negotiated a proposed sale to China Minmetals valued at C$6.7 billion, but the transaction encountered political and governmental scrutiny in Canada. The company subsequently pursued a combination with Falconbridge. The merger was completed in 2005, but the combined business retained the Falconbridge name, bringing the Noranda mining-company identity to an end. Falconbridge was acquired by Xstrata in 2006, and Xstrata was later acquired by Glencore in 2013. The Noranda name survived in certain successor or spun-off businesses, but Noranda Mines itself is defunct.
History
Noranda Mines was incorporated in 1922 under the leadership of James Young Murdoch to exploit the Horne mineral deposit near Rouyn-Noranda, Quebec. Edmond Henry Horne had discovered the deposit on claims staked in 1920. Commercial copper extraction began on 17 December 1927. Although the initial mine plan suggested that the orebody might last only about three years, the discovery of the Giant H orebody substantially expanded the resource base. The Horne mine consequently became the company's operational foundation until its reserves were exhausted in 1976. Noranda began diversifying in 1930, acquiring interests in forestry, oil, manufacturing, and automotive-related activities. In 1931 it opened the CCR refinery in Montréal-Est, integrating copper processing with production from the Horne smelter. Its international expansion began in 1938 with the purchase of the Empresa Minera de Nicaragua gold mine. The company also built a large Canadian base-metal portfolio, including an interest in Kerr Addison Gold Mines, the Gaspé Copper Mines, Canadian Electrolytic Zinc, and Brunswick Mining and Smelting. During the 1960s and 1970s, Noranda continued to broaden its holdings. It sold its Denison Mines investment at a substantial gain in 1967 and redirected capital toward Saskatchewan potash, Brunswick Mining and Smelting, aluminum products, and other materials businesses. Following the 1973 Chilean coup, it reclaimed its 49 percent interest in Chile Canadian Mines and later secured rights to the Andacollo copper reserves. It also opened an aluminum smelter in Missouri and entered the oil business through Canadian Hunter. A major change in control occurred in 1981, when Brascan and the Caisse de dépôt et placement du Québec made a C$1 billion investment and gained effective control. In 1984 the company adopted the name Noranda Inc., signaling its broader corporate scope. That year it entered electronics-scrap and recycling more substantially through the acquisition of Micro Metallics. Noranda later expanded recycling through battery processing and an electronic-hardware facility in Ontario. By the mid-1990s, Noranda was consolidating its position in mining and metals. It gained full control of Brunswick Mining and Smelting in 1995 and acquired the Refimet smelter in Chile in stages, obtaining full control in 1998. In parallel, management decided to reverse the earlier diversification strategy. The company announced in 1997 that it would divest non-mining and non-metals businesses, and the transition was completed the following year with the exit from forestry and oil and gas. Noranda's later growth emphasized large international mining and processing assets. It acquired a 34 percent interest in Peru's Antamina copper-zinc mine, which opened in 2001. It operated or invested in aluminum, alumina, bauxite, copper, zinc, gold, recycling, and related processing businesses, and by 2005 had operations in 18 countries. The company also pursued the Alumysa aluminum project in Chile, but shelved it in 2003. Noranda had acquired 19.9 percent of Falconbridge in 1988 and increased the holding to 58.4 percent in 2002. In 2004, China Minmetals negotiated a proposed C$6.7 billion acquisition, prompting controversy and a Canadian federal review of foreign-investment policy. The offer did not result in a completed transaction. Noranda instead proposed a merger with Falconbridge in January 2005. The merger was completed in June, but the combined company retained the Falconbridge name. This ended Noranda's existence as a major independent mining company. Xstrata acquired Falconbridge in 2006, and Glencore acquired Xstrata in 2013. The Noranda name continued in selected successor businesses, but not as the original diversified public company. Noranda Mines was incorporated in 1922 to exploit the Horne deposit in Quebec. Edmond Henry Horne had staked the relevant claims in 1920 near what became Rouyn-Noranda, and James Young Murdoch led the company during its formative period. Copper production began on 17 December 1927. The Horne mine's expected short life was extended by the discovery of the Giant H orebody, making the operation the backbone of Noranda's business until the depletion of its reserves in 1976. Noranda began diversifying in 1930. In 1931 it opened the Canadian Copper Refiners refinery at Montréal-Est to process copper from the Horne smelter. It entered international mining in 1938 by acquiring the Empresa Minera de Nicaragua gold mine and expanded its Canadian portfolio through an interest in Kerr Addison Gold Mines in 1945. Gaspé Copper Mines opened in 1955, while Canadian Electrolytic Zinc began production in 1963 with Noranda as a major stakeholder. The company broadened its industrial interests during the 1960s and 1970s. It sold its Denison Mines holdings in 1967 after a substantial increase in value and redirected capital toward potash, Brunswick Mining and Smelting, and aluminum-related activities. After the 1973 Chilean coup, Noranda reclaimed its interest in Chile Canadian Mines and later secured rights to the Andacollo copper reserves. It opened an aluminum smelter in New Madrid, Missouri, in 1973 and formed Canadian Hunter to enter the oil sector. Brascan and the Caisse de Dépôt gained effective control after investing C$1 billion in 1981. In 1984 the company adopted the name Noranda Inc., signaling its diversified character, and purchased Micro Metallics to enter electronics-scrap and recycling activities. During the 1990s Noranda consolidated its position in zinc, recycling and Latin American metals. It obtained full control of Brunswick Mining and Smelting in 1995, opened a battery-recycling facility in 1996, and acquired full control of the Refimet smelter near Antofagasta in 1998 after first purchasing a minority interest. Noranda announced in 1997 that it would leave industries unrelated to mining and metals. The transition was completed the next year, ending its forestry and oil and gas involvement. The company subsequently expanded its international metals portfolio. It acquired a 34 percent interest in Peru's Antamina copper-zinc mine, which began operations in 2001, opened an aluminum-foil plant in Tennessee in 2002 and an electronic-hardware recycling facility in Brampton, Ontario, in 2003. It also shelved the Alumysa proposal in Patagonia in 2003. In 2004 it acquired a 50 percent interest in the Gramercy alumina refinery and related Jamaican bauxite assets. Noranda had accumulated a major position in Falconbridge, beginning with a 19.9 percent interest in 1988 and reaching 58.4 percent in 2002. A proposed 2004 sale to China Minmetals for C$6.7 billion became the subject of Canadian political and governmental scrutiny. Noranda instead pursued a merger with Falconbridge, completed in 2005. The combined company retained Falconbridge's name, ending Noranda as a major mining-company identity. Xstrata acquired Falconbridge in 2006, and Glencore completed its acquisition of Xstrata in 2013. Related businesses continued to use the Noranda name, but the original company ceased to exist. Noranda's later growth emphasized large international mining and processing assets. It acquired a 34 percent interest in Peru's Antamina copper-zinc mine, which opened in 2001. It opened an aluminum-foil plant in Tennessee in 2002 and an electronic-hardware recycling facility in Brampton, Ontario, in 2003. It also shelved the Alumysa aluminum project in Chile's Aisén Fjord region in 2003. In 2004 it acquired a 50 percent interest in the Gramercy alumina refinery in Louisiana and related Jamaican bauxite assets. It operated or invested in aluminum, alumina, bauxite, copper, zinc, gold, recycling, and related processing businesses, and by 2005 had operations in 18 countries.
