Geostatistics Tools

Vulcan Geostatistics tools provide a powerful set of grade estimation and resource classification capabilities which enable geostatisticians to gain insight from block models utilising advanced features.

Statistical analysis including contact profile analysis and estimation declustering using kringing, inverse distance / polygonal methods
Variogram calculations utilizing experimental variograms, auto and cross variography, 3D graphical display of search geometry and data, 3D Variogram maps and automatic determination of multiple directions per vector
Variogram modeling using a wide variety of elemental models, interactive 3D modeling with multiple structures and automatic model fitting
Grade estimation through simple, ordinary and multiple indicator kriging, affine and indirect lognormal corrections, indicator simulation and graphical 3D “explanation” of estimation processes
