Abstract: | The production, price and economic resources profiles of a number of mineral commodities are examined and consideration is given to the theory that such profiles can be related to one another within the framework of a life-cycle model of development. While the behaviour of some of the commodities examined appears to lend support to the theory, that of others reveals fundamental problems with its underlying assumptions. It is concluded that, while the demand for a mineral commodity in specific uses may indeed manifest cyclical tendencies, as a general behavioural theory and as a basis for resource estimation the life-cycle model applied to minerals is of little value. |
