Managing metal price risks

Abstract Metal prices are frequently the most critical and least predictable element in determining the profitability of mining operations. Short-term fluctuations can be offset in varying degrees by hedging or other market actions. Such solutions are not practical for the longer term.
The paper investigates the nature and extent of metal price risks and evaluates methods to reduce them.
Keywords: Risk management, Mineral economics, Hedging, Metal prices, Markets, LME COMEX.

Summary: The author will give a capsule history of Benguet Corporation and attempt to identify its operating environment and underlying "strategy" until 1974, when the company's management assumed office. The company's operating environment and "interim strategy" from 1975 to 1980 will be described. The discussion will cover an environmental forecast and define the company's "strategy for survival" for the balance of this century.

Summary: Risks from political instability and government policies restricting equity ownership, local operations and transfers of payments affect the profitability of foreign mining ventures. More than seat-of-the-pants judgments and old-boy networks are required to anticipate these risks and to take actions appropriate to offsetting them. A system for making political forecasts, called the Prince System, and a series of charts relaying risks to a production of key minerals will be presented.

Summary: The oil crisis accelerated the change of non-ferrous metals' demand structure. Maturing societies in developed countries and preference for lighter, thinner and smaller products are eroding the non-ferrous metal industries' growth potential. Inventory-control, stockpiling and developing new demand are measures Japanese smelters have taken to cope with the changing demand.
The most effective means for risk management of product demand lies in the cooperation between ore producing countries and...

Summary: The dispersion of diesel contaminants into the mine atmosphere is a variant of general class of diffusion-dilution problems relevant to underground mining practice. The equipment operations in underground mining are characterized by different activities with different time durations, i.e. varying duty cycles. Therefore the volume and quality of diesel emissions and consequently, instantaneous concentrations are quite variable. Design of mine ventilation systems under these conditions becomes...

Summary: Modern microprocessor systems make it possible to use several variables to anticipate changes in the process and to react with responses before upsets can be magnified by the process or by control action.
Through tighter control, "insurance" can be eliminated from process set points without affecting product quality. In actual operation with a traveling grate furnace this control philosophy has produced savings of up to 20% in fuel consumption and 8% in fan power usage while...

Summary: Quality of iron ore is generally determined by several factors which can be correlated or independent. Among these factors, we generally find per cent iron, silica, magnetite or hardness. Forecasting the short- and long-term fluctuations of these factors in the future pit is an important feature of mine planning in these deposits. Computer simulation provides a realistic answer to these questions. It allows to generate values for the most important quality features of each shovel load with...
