dc.description.abstractA gravity survey program conducted by Atlas Geophysics Pty Ltd was successful according to its aim to generate a higher resolution of gravity data for the Jervois project EL 30294. A new 1km X 1km density gravity dataset is now available which will provide a clearer definition of the geology which is largely obscured at surface by transported sandy cover and could not be interpreted to a high degree of confidence with the original 2km X 2km survey data density. A preliminary interpretation of the new dataset has identified key geological features, including the regional Lucy Creek fault and the extension of prospective Bonya Schist in the north-western corner of the survey area. Further exploration for base-metals is proposed for this part of EL 30294. Higher density gravity data now provides a better definition of granite intrusive which has been interpreted to be much more limited in area in contrast to the original interpretation. The survey has identified potential for other lithologies, including prospective mafic or ultramafic rocks to be more widespread than previously recognised and this has added to the prospectivity of EL 30294. Future exploration on EL 30294 will aim to explore areas of positive gravity response to confirm the possible presence of mafic or ultramafic rocks which are age-equivalent to the prospective Bonya Schists which host copper-lead-zinc and silver-gold mineralisation at the Jervois field located further west. The survey has also identified a number of faults that trend sub-parallel to the regional Lucy Creek fault, with a number of offsets along an oblique NW/SE-strike trend indicating potential for a new target trend. A relationship was identified between some of the contacts/structures interpreted from the 1VD survey image and the distribution of the 4 deep-rooted tree species which highlights potential of the geobotanical mapping as an exploration method that could be applied in a cost-effective manner during the early reconnaissance stage of an exploration program.en_US
