The aim of this consultant's economic geological review was to ascertain whether any now obvious but still untested targets remained in the Wallaroo - Moonta mining area after 20 years of intensive exploration. WEST DOORA - VULCAN: This line of lodes is regarded as a deformed, metamorphosed submarine exhalative copper deposit related to mafic volcanism (i.e. the Doora Schist). Underground exploration in the past has been carried out to a depth of 400 metres at West Doora and 100 metres elsewhere. More copper ore is probably present down dip, but the grade of the mineralisation is not expected to differ markedly, and hence deeper exploration is not warranted. The ore horizon represents a specific stratigraphic horizon close to and near the eastern contact of the Moonta Porphyry (an acid volcanic rock coeval with the Doora Schist). This same stratigraphic horizon has also not been explored at depth along the western contact of the Moonta Porphyry, and is seen as a similar target to the deep lode extensions. OLYMPIC DAM - TYPE MINERALIsATION: A number of coincidental gravity and magnetic anomalies warrant further checking. URANIUM POTENTIAL: Uranium minerals occur frequently in the Early Proterozoic rocks, and uranium enrichment occurs in some of the Middle Proterozoic granitic rocks. 2 widely spaced diamond drill holes at Alford intersected a zone of uraninite in the thermal metamorphic aureole, and this zone needs further testing. The deep weathering of the uraniferous source rocks in the area, and overlying Tertiary fluvial sequences containing lignitic sands, represent an attractive environment for roll-front uranium deposits. The Quaternary carbonate-rich, inwardly-draining saline lakes overlying and draining from a large area of the uraniferous source rocks represent an attractive target for calcrete-type uranium deposits.
