Abstract:
The Acropolis prospect is a vein-style magnetite (±apatite ±hematite) system located ~20 km southwest from the giant Olympic Dam iron-oxide copper gold (IOCG) deposit, South Australia. A whole rock dataset comprising 4,864 core samples from fourteen drillholes was analysed using multivariate statistics to understand and identify geochemical signatures of mineralization at Acropolis. Statistical analyses included principal component analysis, hierarchical and k-means clustering. The results of statistical analyses are overlaid and interpreted relative to a 3D implicit geological model of the prospect, and encompass a projection of mineralization signature as PC1.
