Copper mineralisation at the Mount Mary workings is restricted to a large E-W trending fault that emanates from the Blinman Diapir. Minor cross-shear fractures along this fault are filled by quartz-siderite veins that carry malachite plus some...

Copper mineralisation within rafted Early Adelaidean metasedimentary blocks in the Patawarta Diapir is widespread but thin and discontinuous, being found primarily in ferruginous calcite veins and sometimes in the enveloping siltstones. Some...

Report briefly describes the geology, structural features and mineralisation present in both the diapir core and its rim rocks. Some observations about the extent and the origin of mineralisation are made, but the overall assessment is ongoing.

Two vertical rotary percussion drillholes totalling 490 feet were put down on a zinc-rich gossan at the Patawarta prospect, which had been discovered through soil sampling of the Late Proterozoic Bunyeroo Formation calcareous siltstone subcrop...

Isolated old workings evidence the presence of small pockets of both galena and polysphaerite (lead phosphate) developed along a strong N-S trending fault zone, which radiates from a small circular diapir lying to the north of the Blinman Diapir. A...

3414 geochemical reconnaissance stream sediment samples were taken over an area of 277 square miles for NFM during the period December 1969 - August 1971, and analysed for anomalous Cu/Pb/Zn in Sturtian-Marinoan to Lower Cambrian bedrock...

An intensive search for copper and base metals was carried out 1965 - 1972 by both companies and SADM, with no discoveries being made. Geophysical and geochemical methods were used extensively.
