    In order to determine whether it is desirable to quantify mineral-deposit models further a test of the ability of a probabilistic neural network to classify deposits into types based on mineralogy was conducted. Presence or absence of ore and alteration mineralogy in well-typed deposits were used to train the network. To reduce the number of minerals considered the analyzed data were

    Geologists classify mineral deposits in many different ways according to the commodity being mined. tectonic setting in which the deposit occurs. geological setting of the mineral deposit. genetic model for the origin of the ore deposit. The most commonly used scheme is the genetic classification scheme.

    Across all deposit types 88 of deposits in the validation dataset were correctly classed. Misclassifications were most common if a deposit was characterized by only a few minerals e.g. pyrite chalcopyrite and sphalerite. The success rate jumped to 98 correctly classed deposits when just two rock types were added.

     · Classification of Mineral Resources and Reserves. In the early days of mining there were no standards for the reporting of mineral assets. Companies or individuals would usually take grades observed in drill core and using some clever geometry extrapolate them to define a deposit. This usually involved a large amount of guesswork and errors
