Secondly, we show how petrophysics can substitute for, and circumvent the lengthy process of chemical analysis for iron ore grade estimation. Although the spectral gamma-gamma data used in our study is experimental in nature and not calibrated to a specific iron ore prospect, the lithology and grade prediction is over 80% correct.
