In a search for extensions of the Baratta silver-lead mining field mineralisation, eastwards under alluvial cover, a 7 miles long x 3 miles wide grid was laid out over the inferred most favourable location for a buried strike extension of the host rocks, and detailed geological mapping of scant outcrop in the vicinity of the licence, plus ground magnetic surveying, orientation soil sampling (93 samples), iron-rich lag pebble sampling (272 samples), vegetation sampling for biochemical tracers (211 samples) and soil mercury sampling (616 samples) were undertaken. The highest soil mercury value obtained was 50 ppb Hg, which is insignificant.Four attempts to reach the bedrock for geochemical rock sampling, made with an auger drill rig, proved unsuccessful owing to this equipment meeting with an impenetrable conglomerate layer at less than 50 feet depth. Subsequently, considerable RAB drilling (> 350 holes for a total penetration of 39,185 feet) was carried out over the sampling grid during the period January-June 1971, successfully reaching the bedrock in most drillholes and sampling it for base metals and for scintillometric scans. However, the assay and radiometric results were not deemed to be encouraging, so therefore the licensee decided to give up the ground.
