A detailed investigation into the reconciliation of hyperspectral core data and platinum-group element grade

摘要

The Northern Limb of the Bushveld Complex represents an exciting frontier for mining development and mineral exploration. The Ni-Cu-platinum-group element (PGE) orebody of the Platreef (and 'Flatreef) allow for large-scale, relatively low-cost mining amenable to mechanization. Alongside bulk-geochemical data and 'traditional' core logging, hyperspectral imaging has been identified as a potentially powerful exploration tool in the hydrothermally overprinted rocks of the Platreef. Hyperspectral imaging of Anglo American's modern and legacy drill core aims to introduce a new approach that increases productivity of existing projects in the region and identify new targets.
