An area surrounding the historically worked Ediacara lead-zinc Mineral Field, overlying the inferred far eastern margin of the Gawler Craton, is being explored for possible economic hydrothermal/stratabound base metals within the Adelaidean and Cambrian cover rocks, and for IOCG style copper-gold mineralisation within the underlying older ?Mesoproterozoic basement. Because the existing regional gravity data coverage for the licence area was sparse over its central and southern sections, Minotaur Exporation chose to undertake a new gravity survey covering the entire tenement, with readings acquired at a 1 km x 1 km spacing in general, infilled to 500 m x 500 m apart across the licence's southern part. 1129 stations were read during October and November 2007, including some closely spaced stations laid out along two east-west traverses that cross the northern and southern ends of the Ediacara Range. Gravity data from 235 of the new gravity stations are being released herein since their locations lie within the now relinquished north-eastern portion of EL 3951. Interpretation of these data shows uniformly low residual gravity values consistent with a very thick sedimentary succession present in the westernmost portion of the Neoproterozoic Adelaide Geosyncline. Available drillhole logs also indicate that locally, Tertiary sediments up to ~100 m thick are present within concealed Tertiary palaeochannels lying between exposures of Neoproterozoic sediments, both to the west near Mount James and to the east near Mount Deception. As the relinquished portion of EL 3921 was thought to contain only Neoproterozoic or younger strata, then its potential to host IOCG-style mineralisation was considered to be very low.
