Multivariate iron ore deposit resource estimation a

Non-linear estimation and conditional simulation (CS) are alternative geostatistical approaches that can provide more reliable estimates of the recoverable tonnage and grade (i.e. the ultimate production gradetonnage relationships) from wide-spaced drilling. Non-linear estimation and CS are not commonly used on iron ore deposits.
