Hyperspectral mineralogy can be applied in the production environment, particularly in support of ore/grade control and geometallurgy. Where ore minerals can be detected spectrally, such as in lithium deposits, hyperspectral imaging provides a rapid and accurate method to determine mineralogical deportment and to separate domains of varying ore mineralogy.
Even where ore mineralogy is not spectrally detectable, alteration minerals directly associated with the orebody can be identified and mapped to aid in defining the ore zone. This is of particular use in nuggety orebodies, where grade fluctuations are extreme and defining the ore zone is difficult to do based on assays alone.
In our experience, it is changes in mineral chemistry that are often the defining characteristic of ore associated alteration, and which simply cannot be identified without hyperspectral data.
