Abstract: | The factors which influence the size and value of mineral reserves are discussed and an example is given of a more rigorous system for measuring supplies of non-renewable resources.The extent to which reserves and resources of minerals can be used as leading indicators of future mineral production is examined and examples of the dangers of over-reliance on this factor are described.Key aspects, such as confidence limits, differences in the economic exploitability, the dynamic nature of reserves, and their variability in grade, are examined in some detail using the South African coal industry as an example. |
