Abstract
Due to the extreme costs of establishing new shaft systems in Witwatersrand gold
mines it is essential that the resource estimation is optimised, The result of poor
Of sub-optimal estimation could be catastrophic even.to the largest of mining
companies.
This project examines the application of Compound Lognormal Distribution
theory and shows the advantages of this distribution model over more traditional
models, for the Carbon Leader Reef. The incorporation of information from
mined out areas of a deposit in resource estimation is demonstrated. The critical
role played by accurate geological modelling is highlighted.
The process of Macro Co-Kriging in conjunction with Compound Lognormal
Theory is discussed in detail and is shown to be a more accurate estimation
technique than traditional techniques using Lognormal theory.
Finally the use of the Macro Co-kriged limits are shown to be useful in the
classification of Mineral Resources.
