Overview

Rhodesian Selection Trust (RST) was a British mining corporation established in 1928 by Alfred Chester Beatty, an Irish-American mining entrepreneur, to hold and develop his mining interests in Northern Rhodesia, the territory that became Zambia in 1964. Its business was concentrated in the Copperbelt, one of Africa's most important copper-producing regions, where the company operated mines and associated processing facilities through subsidiaries and divisions. Copper was its principal product, with cobalt produced as an associated mineral from Copperbelt ores. RST's growth depended on international finance and industrial relationships. In October 1930, the American Metal Company of New York acquired one million shares in RST, providing an important American financial connection. The company became one of the major corporate participants in the Northern Rhodesian copper industry alongside other large mining groups. Its operations combined extraction with smelting and refining activities, giving it a substantial role in the production chain rather than limiting it to mine ownership. The company remained publicly visible as a substantial copper producer during the late colonial period. For the fiscal year ended June 30, 1960, RST and its principal subsidiaries reported combined net earnings of $13,132,546, compared with $8,780,651 in the preceding year. For the year ended June 30, 1964, sales increased to $165,736,718 from $142,605,518 in 1963, while profit declined modestly from $16,691,000 to $16,517,000. These figures illustrate both the scale of its operations and the sensitivity of mining earnings to commodity-market conditions. RST also became involved in debates about copper pricing and the political transition from colonial rule to independence. Chairman Sir Ronald Prain advocated offering copper outside the speculative London Metal Exchange framework at prices below exchange quotations, and in 1964 he argued with Anglo-American Corporation for greater copper-price stability. Following the creation of the Republic of Zambia in October 1964, the company continued operating in the newly independent country. In December 1964, Rhodesian Selection Trust Ltd changed its name to Roan Selection Trust Ltd, while its Roan Antelope Division was renamed the Luanshya Division. The renamed company subsequently became closely connected with American Metal Climax, commonly known as AMAX. In 1970, Roan Selection Trust, which had previously been 42.3 percent owned by AMAX, became an AMAX subsidiary through a corporate reorganization. The reorganization took place during the implementation of Zambia's policy to nationalize its copper properties. RST's Zambian mining, smelting, and refining assets were consolidated into Roan Consolidated Mines Ltd. The state-owned Industrial Development Corporation, or Indeco, was to hold a 51 percent interest, while the remaining equity was divided between Roan Selection Trust and interests associated with Anglo-American Corporation. The corporate structure created by the nationalization process was later absorbed into Zambia's state-led copper industry. In 1982, Roan Consolidated Mines and NCCM were combined to form Zambia Consolidated Copper Mines Ltd (ZCCM), one of the country's dominant mining entities. Although the original Rhodesian Selection Trust name had disappeared decades earlier, its assets and successor companies remained part of the institutional history of the Zambian Copperbelt. The later corporate lineage of AMAX continued through its 1993 combination with Cyprus Mines Corporation to create Cyprus Amax Minerals Company, followed by its acquisition by Phelps Dodge in 1999 and Phelps Dodge's acquisition by Freeport-McMoRan in 2007. These later transactions concern successor corporate structures rather than an active RST brand.

History

Rhodesian Selection Trust was formed in 1928 by Alfred Chester Beatty as a holding company for his Northern Rhodesian mining interests. Its creation reflected the increasing importance of the Copperbelt and the need to organize mine ownership and financing through a corporate vehicle capable of attracting international capital. In October 1930, the American Metal Company of New York purchased one million RST shares, creating a significant American financial relationship. RST developed into a major producer in the Northern Rhodesian Copperbelt. Its activities included copper mining and associated processing, including smelting and refining. Cobalt was also recovered as an associated mineral. The company operated through divisions and subsidiaries, including the Roan Antelope operation, later renamed the Luanshya Division. Its scale made it one of the important corporate institutions shaping the colonial economy of Northern Rhodesia and the industrial development of the Copperbelt. The company's financial results in the late colonial period demonstrate its importance. RST and its main subsidiaries earned $13,132,546 in the fiscal year ended June 30, 1960, compared with $8,780,651 in the preceding year. In 1964, sales rose from $142,605,518 to $165,736,718, although profit fell slightly from $16,691,000 to $16,517,000. During this period, chairman Sir Ronald Prain took a public position on the copper market, supporting efforts to moderate price volatility and arguing that copper should be offered outside the speculative London Metal Exchange at a price below the exchange level. The political setting changed decisively in 1964, when Northern Rhodesia became the independent Republic of Zambia. In December of that year, Rhodesian Selection Trust Ltd changed its name to Roan Selection Trust Ltd. The Roan Antelope Division was simultaneously renamed the Luanshya Division, aligning the corporate terminology with the new national context. The company's operations continued to be economically significant, but the future ownership and governance of Zambia's copper industry became increasingly subject to state policy. In 1970, Roan Selection Trust underwent a reorganization associated with American Metal Climax, or AMAX. AMAX had previously held 42.3 percent of Roan Selection Trust and became its sole owner after the reorganization. At the same time, the Zambian government was implementing the nationalization of copper properties. Roan's Zambian mining, smelting, and refining operations were transferred into a consolidated company called Roan Consolidated Mines Ltd. Indeco, a state-owned industrial corporation, was designated to acquire a 51 percent equity interest, while the remainder was allocated to Roan Selection Trust and interests linked to Anglo-American Corporation. The RST corporate identity therefore gave way first to Roan Selection Trust and then to successor entities within Zambia's state-controlled mining system. In 1982, Roan Consolidated Mines and NCCM were merged into Zambia Consolidated Copper Mines Ltd, creating a much larger national copper enterprise. The original RST name was no longer an active operating brand, but its assets, divisions, and corporate relationships remained part of the Copperbelt's industrial succession. The later history of the AMAX lineage extended beyond Zambia. AMAX merged with Cyprus Mines Corporation in 1993 to form Cyprus Amax Minerals Company. Cyprus Amax was acquired by Phelps Dodge in 1999, and Phelps Dodge was acquired by Freeport-McMoRan in 2007. These transactions help trace the broader corporate lineage of assets and shareholders associated with RST, but they do not indicate that Rhodesian Selection Trust itself remained an operating company under its original name.

Products and positioning

A major international copper producer operating in the Northern Rhodesian, later Zambian, Copperbelt.

  • Base metal

    Copper

    Copper was RST's core product and the economic foundation of its Northern Rhodesian and later Zambian operations. The company participated in mining, smelting, and refining through its Copperbelt divisions and subsidiaries. Its production contributed to the emergence of the Copperbelt as a major international source of copper.

  • Associated base metal

    Cobalt

    Cobalt was produced as an associated mineral from the Copperbelt ore bodies operated by RST. It was secondary to copper in the company's portfolio but formed part of the mineral output associated with its mining and processing activities.
