Abstract
Waihi Au-Ag mineralization is vein hosted within a relatively homogeneous andesite body. Geochemical exploration targets adularia and pathfinder (As, Sb, Hg etc.) anomalies. Adularia is formed as an alteration product of feldspars during hydrothermal alteration and occurs in anomalous concentrations near Au-Ag mineralization. This paper aims to test the potential of portable X-ray fluorescence (pXRF) to infer and map adularia and As anomalies. The pXRF was first tested on standards (CRM and ILD), it yielded accurate and precise data for most of the elements of interest (r2 > 0.9 and APD
