Exploration Licence 2687 ‘Yandina Hill’ is located 500 km north of Adelaide in the North Flinders Ranges. The area lies within the northern part of the Adelaide Geosyncline, a deformed sedimentary basin of Late Proterozoic to Middle Cambrian age, flanked by the crystalline basement complexes of the Gawler and Curnamona Cratons. Zinc, lead and copper mineralisation is found throughout the geosyncline generally associated with lithologies of Cambrian marine shelf carbonate environments. Following the Delamerian Orogeny, diapirism and metasomatism were active which resulted in base metal deposits becoming localised in particular stratigraphic and structural settings. During licence Year 1, ‘Yandina Hill’ was examined as part of a larger regional exploration program of tenements held by Perilya, targeting known zinc mineralisation occurrences. The mineralisation potential of the held tenements was also investigated with the view of rapidly reducing the ground held. Open file research desktop reviews were completed, and a Regional Prospect Database created. The acquisition, processing and interpretation of AGSO geophysical data for the region was undertaken and Landsat imagery was acquired to assist in the ongoing evaluation of the area and to assist in prospect generation. During licence Year 2, no work was undertaken on the licence area. Exploration activities outside of cleared areas was ceased until Native Title issues had been resolved and agreements signed.
