Adelaide Fold Belt (South Australia)
Renascor has identified the potential for large tonnage Zambian Copper Belt-style, sedimentary copper deposits with a prominent copper belt in South Australia.
The Farina Project is made up a large, copper-prospective ground position within South Australia’s Adelaide Fold Belt (see Figure 1 Farina Project, showing geology and historical copper occurrences). Renascor’s exploration program here is focused on identifying and drilling prospects for potentially large tonnage Zambian Copper Belt-style, sedimentary copper deposits.
The sedimentary sequences of the Adelaide Fold Belt have long been recognised as distinctly analogous to the copper-rich Zambian Copper Belt, offering prospects for large tonnage sedimentary copper deposits. In the 1970s and early 1980s, some significant exploration programs adopted the Zambian-style sedimentary copper model within Renascor’s current project area, resulting in intersections of significant ore-grade copper in areas identified from detailed geological mapping and geochemical targeting. (See Figure 2.)
Renascor’s review of historical exploration in the project area has resulted in the identification of a new copper prospect, Callanna, located within an area of historical drilling on the northwest margin of exposed Adelaidean rocks. In addition, Renascor identified two prospective sedimentary copper target zones where sediments are inferred to exist beneath shallow cover and hence, amenable to EM surveying. Ground sampling undertaken during the reporting period focused on historical copper occurrences at the Callanna prospect. Results included strongly anomalous gold values (maximum 2.6 g/T gold) associated with oxide copper mineralisation. A single hand-picked sample from a small working approximately 3 kilometres north of the main Callanna prospect area returned 27% copper and 0.4 g/t gold with strongly anomalous rare earths and molybdenum, suggesting a possible granitic intrusive association.
Further work programs in the project area are expected to include additional soil geochemistry and airborne EM surveys prior to drill-testing.
