A large area on Lake Everard Station, extending for ~44 km north-south through the Gawler Ranges immediately south of Lake Gairdner, has been explored for possible buried epithermal gold which may occur along the south-eastwards trending arm of the Palaeoproterozoic Yarlbrinda Shear Zone in a place where where it is concealed by younger volcanic strata. This major shear zone is a broad and complex structure, which has both southwards and south-eastwards trending components that bifurcate near Tunkillia. The structure was a conduit for Mesoproterozoic hydrothermal fluids associated with widespread magmatism (Gawler Range Volcanics and Hiltaba Suite), which engendered the emplacement of Au+Ag mineralisation at Tunkillia in splay fault trap settings. The south-eastwards trending arm of the Yarlbrinda Shear Zone extends across the subject EL 5096, although it is concealed by younger volcanic strata, and it may extend beyond there for another 120 km and be the primary structural control for NW-SE oriented mineralisation occurring at the Paris prospect. During the first licence year, Minotaur reviewed available geophysical and geological data for any included aspects that might support its exploration model. From this office-based work it was recommended that reconnaissance IP and CSAMT surveying be undertaken across the interpreted trace of the buried target structure. During licence Year 2, no work was done. A decision was made to allow tenure to lapse.
