Abstract
Preliminary steps of mineral exploration have always included drilling and other destructive and expensive exploration techniques to quantify ore-deposits underground. This study examines how we can access information on the sub-surface geology by looking at the surface vegetation. We have targeted gold-mineralization along the Hyde-Macraes Shear Zone as a development site, which is located in the Otago Schist belt in southern New Zealand. Deep rooted plants, of the Pinus radiata species, were sampled on the field to quantify the element concentrations focusing on the pathfinder elements such as As and Fe in the host rock, in conjunction with airborne and laboratory based hyperspectral remote sensing data. In order to predict the elemental concentration from hyperspectral data Partial Least Squares Regression (PLSR) was executed.
