Most ore bodies have an oxide zone when near surface. This one doesn't look magmatic from the photos so not a Nova and replacement of olivine indicates hydrothermal orebody (Nova is distinctly magmatic). Company says it is located within "re-worked" Yilgarn craton, which is Archaean in age where as Nova is located in high metamorphic grade Proterozoic sediments. The elemental abundance would suggest a Cu-Zn-Ag-Au VMS. Potassic alteration (phengite/sericite) and chlorite as per below diagram matches geo summary. The geophys pic matches thsi style. They can be barren or rich in in precious and base metals (ie Scuddles, Golden Grove). Probably drilled through the footwall so need to determine stratigraphy and find the hanging wall contact where the sulphide zone is, which have most of the goods (if present). Ni and Co anomalies likely due to the footwall being ultramfics.
