Abstract

This article deals with the availability of demonstrated resources of copper in market economy countries. It examines the costs for mining and milling from producing as well as developing and explored deposits. While the resources are inadequate, the engineering and cost estimates indicate that a price of $1.50 per pound in 1981 U.S. dollars will be required to sustain existing capacity and bring on 2.2 million tons of new capacity of primary copper. Cet article traite de la disponibilité des ressources prouvées du cuivre dans les pays à économies de marché. Il étudie les coûts d'extraction et de transformation se rapportant aux gisements productifs ainsi qu'aux gisements en développement et à ceux qui viennent d'étre découverts. Bien que les réserves soient suffisantes, l'ingénierie et l'estimation des coûts montrent qu'il est nécessaire d'investir une valeur de 1,50 de dollars des Etats‐Unis par livre en 1981 pour maintenir la capacité de production et permettre une nouvelle capacité de 2,2 millions de tonnes de cuivre primaire. Este artículo trata sobre la disponibilidad de recursos demostrados de cobre en países con economía de mercado. Examina los costos de extracción y molido de minerales de los depósitos en producción asi como de aquellos en desarrollo o exploración. Si bien es cierto que los recursos son adecuados la ingeniería y la estimación de costos indican que el precio de 1.50, dólares de 1981 por libra será necesario para sostener la capacidad existente y poner en operación una capacidad adicional de 2.2 millones de toneladas de cobre primario.
