Two contiguous exploration licences, ELs 6522 and 6523, were secured in the Yudnapinna district to apply new concepts and techniques aimed at revitalising the rate of copper-gold mineral deposit discovery in South Australia. The licences’ area lay outside the generally accepted corridor of potential for IOCG deposits, with few adjacent tenements existing at the time of application. A new paradigm developed by Austrike invoked a universal strato-tectonic crustal model, and formulated new targeting tactics to use for searching near the belt of IOCG deposits along the Elizabeth Creek Fault and for investigating the emerging coeval belt of epithermal/porphyry deposits in the vicinity of the Uno Fault, which were believed to have formed under the umbrella of a single Olympic Metallogenic Event (OME). Austrike proposed that the Yudnapinna district lies on the tectono-metallogenic transition between those belts, and accordingly has potential for IOCGs, porphyry copper gold deposits and possible hybrids. Yudnapinna was thought to be a good example of where the next level of opportunity may exist to apply new ideas in exploring the shallow-covered extensions of pedigree mineralised belts that have previously been both technical and investment challenges for the industry. During the twelve months of tenure that included COVID restrictions, office-based studies iterated existing data provided by past explorers and government surveys with the licensee's new concepts and interpretation techniques. The Yudnapinna district was confirmed as being in a prime tectono-metallogenic position, particularly as indicated by the National Geochemical Survey of Australia (NGSA) data and the AusLAMP magneto-telluric models jointly developed by the Geological Survey of South Australia and Geoscience Australia. A strong IOCG pathfinder signature in the NGSA data for the Yudnapinna catchment coincides with a continental crustal structure plus a kink in the MT corridor connecting the two belts at the mantle interface. This coincidence is indicative of favourable metal sources and pathways to the 1590 Ma palaeosurface. The potential field data show a circular magnetic feature at Dingo Hill nominated as a target for a porphyry copper deposit (PCD) plus a number of gravity anomalies with IOCG potential. These targets are well located to be up-drainage sources to the NGSA anomaly. The past drilling was re-appraised using the new concept of a common mid-GRV strato-tectonic marker for the OME and simplified pathfinder geochemical vectors developed by Austrike. Some of the drill assays included early 4 acid-ICP and fluorine analyses suited to this purpose. These further upgraded the Dingo Hill PCD target and many of the gravity targets. A review of past drill sample assay results highlighted that in the sedimentary cover there is copper and fluorine anomalism at the basal unconformity of the Pandurra Sandstone. This unit is prospective for stratabound copper mineralisation, and the pathfinder element enrichments are seen as indicative of possible remobilisation from, or re-activation through the prospective basement. Contouring of the prospective unconformity showed large target areas where it lies at shallow depth and has undrilled potential for stratabound copper deposits. On 21/9/2021, Austrike allowed the subject licence to expire without seeking to renew it. Future exploration and research programs are hereby recommended to test the nominated targets and in so doing demonstrate the value of improving the minerals systems concepts and approaches being applied in under-explored regions of South Australia. Adopting this approach should include follow up of government data such as the NGSA and AusLAMP, and any such action by explorers should not only be applied to so-called greenfields terrains but is also required to revitalise districts within supposed mature brownfields belts.
