Reconnaissance, helicopter supported mapping and sampling within the Yellabinna Regional Reserve, 70 km north-northwest of Ceduna, revealed more extensive basement outcrop than previously recorded, but returned no anomalous metal values. Infill aeromagnetics confirmed 17 target areas indicative of shear zones or faults active during emplacement of Hiltaba Suite granites, which may have been conducive to possible detrital Au deposition in sediments or breccias near a basal unconformity. The majority of these targets fall within Native Title claim zones excluded from heritage clearance, thereby preventing geochemical follow-up.
