Hyperspectral Core Scanning: A Geologist’s Guide to Quality Results

Abstract

Hyperspectral core scanning is an important tool for rapid, nondestructive mineralogical characterization of drill core in mineral exploration and mining. However, the expanding range of instrumentation types, spectral ranges, and data-processing methodologies has created uncertainty among end users regarding the reliability and interpretation of scan outputs. This paper provides practical guidance for geologists involved in the design, implementation, and evaluation of hyperspectral scanning programs. Key aspects of hyperspectral data acquisition, pre-processing, and mineral identification are reviewed, with emphasis on understanding the types of results that can be generated from scanning systems. Because industry standards for hyperspectral data processing and reporting remain limited, particular attention is given to quality control (QC) procedures that allow users to evaluate data reliability. Recommended QC approaches include the use of spectral standards, replicate scans, reference materials, and independent analytical verification. Applying these practices allows geologists to assess the precision and accuracy of hyperspectral results and to ensure that mineralogical interpretations derived from scanning data are robust and suitable for integration into exploration and mining workflows.
