Three potentially economic gold and platinum / palladium - bearing, known primary uranium-mineralised targets in the Palaeoproterozoic Houghton basement inlier have been evaluated through the conduct of office-based geological and geophysical studies, followed by field reconnaissance and geological mapping, by sampling and re-logging archived drill cores from earlier uranium exploratory drilling (105 samples assayed for Au, Pt and Pd), and by assaying likewise 259 rock chip and 329 soil samples, as well as by running a small ground magnetic survey over a tight bullseye aeromagnetic anomaly seen near Simmonds Hill, located 3 km south of Kersbrook. Detailed geophysical interpretation by consultant D.M. Barrett of the limited amount of available airborne magnetic and radiometric data covering the inlier revealed few features of interest. A north-west trending magnetic anomaly appears to be associated with an albite alteration zone present south of Kersbrook. No strong uranium radiometric anomalies were noted in the region. The drill core study confirmed a previously reported (J. Santul and Uranerz Australia, 1988) association of Pt-Pd anomalism in Barossa Complex calcsilicate rocks with known sub-economic uranium mineralisation, while the albite-rich altered host rock mineralogy seen in mineralised drill cores from the Inglewood and Houghton/Hermitage prospects now suggests that it may be part of a low sulphur, iron oxide - associated Cu-Au-U system preserved within the basement, with the drill sampled remnants coming from the zone of sodic alteration which is characteristic of burial depths of > 1-2 km beneath an original high grade IOCG orebody. At Inglewood prospect, rock chip sampling of a road cutting exposure of basement located 60 m south-east of the now inaccessible SADM DDH1 drillhole site returned assay values of 13 ppb Pt and 96 ppb Pd, which was by far the highest surface sample result obtained from anywhere in the inlier. Soil sampling conducted directly across and to the north of this small prospect did not show any meaningful anomalism. At the larger Houghton prospect, mapping demonstrated the existence of an extensive alteration zone, and rock chip sampling confirmed the low grade of Pt-Pd mineralisation previously identified, without revealing any higher grades. Because the follow-up surface geochemical work did not produce any significant Pt-Pd values over these previously drilled uranium-rich prospects, this result downgraded or eliminated the prospectivity of a number of the licensees' other identified platinoid metal targets, and left of interest just the gold potential of faulted metasediments in the vicinity of the historic Stockyard Gully and Para Wirra gold diggings in the western part of the licence area, where surface samples taken from 150 m north of the main Para Wirra mine yielded gold values of up to 14 ppb Au in laterite soil. However, it became clear that the centre of this particular target locality lies within land Section 419 which in 1983 was excluded from the operations of the Mining Act. The licensees subsequently made an application to the State Government for a reversal of the legislated situation so that necessary mineral reconnaissance work, including RC drilling of gold lodes along strike, could proceed under the terms of a mineral claim, but the land access issue was unable to be resolved before the initial term of the licence expired. Shortly thereafter the licensees chose to stop exploring on this tenement.
