Drill core analytical tools are used for objectively measuring geoscience parameters that aid mineral exploration or groundwater research. Multiple types of geoscience parameters are frequently compared alongside each other, but underlying physicochemical relationships are seldom explored. If the relationships between different parameters are understood, 1) expensive measurements can be inferred from more cost-effective measurements and 2) workflows can be developed that enable fast and objective selection of samples for further, more timeconsuming sample analysis. Ultimately, linking geophysical, geochemical and mineralogical parameters could give rise to a new generation of higher-level geoscience products reconciling different sources of information. This paper describes some of the causative relationships between hyperspectral, geochemical and petrophysical data using drill core data sets made available by AuScope's National Virtual Core Library (NVCL) infrastructure program.
