The Stavely Project is a collaboration between Geoscience Australia and the Geological Survey of Victoria. During 2014 fourteen pre-competitive stratigraphic drill holes were completed in the prospective Stavely region in western Victoria in order to better understand subsurface geology and its potential for a variety of mineral systems. The Stavely region hosts several belts of poorly-exposed Cambrian volcanic and intrusive rocks, visible largely only in aeromagnetic data, which have similarities to those found in modern subduction-related tectonic settings. Mineralisation associated with porphyry Cu-Au and volcanic-hosted massive sulphide mineral systems is known where these rocks are exposed around Mount Stavely and the Black Range. However, despite a history of mineral exploration dating back to the late 1960s, significant economic deposits are yet to be discovered, and the Stavely region remains a greenfields terrane. Given the geological setting and known mineral potential, opportunity exists for the discovery of large mineral systems beneath extensive, but relatively thin, younger cover. The Stavely Project aims to provide the framework for discovery in the Stavely region primarily through the acquisition and delivery of pre-competitive geoscientific data. This includes the completion of pre-competitive stratigraphic drill holes in order to test regional geological interpretations and recover material for detailed lithological, petrophysical, geochemical and geochronological analysis. The results will assist in understanding the mineral systems potential of the Stavely region under cover. This report describes the scanning methods and procedures used to measure rock properties of the diamond core from 13 of the 14 Stavely Project stratigraphic drill holes. A brief summary of core quality, generalised lithologies and petrophysical responses, together with associated metadata for each scanned drill hole is presented, along with visual logs of the petrophysical data. Processed petrophysical data is provided for download with this report. Analytical methods for each of the petrophysical properties measured are also documented.
