Integration of Conventional and Downhole Geophysical Data in Metalliferous Mines

Geophysical logs provide valuable data that can be linked to orebody modelling and mine planning in metalliferous mines; however, geophysical measurements provide indirect data for ore grades and require further integration with conventional assay data. Integration can be based on the generation of suitable geophysical data compositing and the use of the sequential co-indicator simulation with the Markov-Bayes approximation. A detailed study at the Kidd Creek base metal mine, Canada, shows the practical aspects of the suggested approach and the value of integrating geophysical data.
