RoXplorer® on site during the recent Port Augusta field trials.
The RoXplorer® CT Rig was successfully commissioned.
The trial was undertaken approximately 20 km west of Port Augusta on the Eyre Peninsula, South Australia. A diamond hole had been previously drilled at the site during the Mineral Systems Drilling Program. The site provided a typical example of the thick cover sequence of the Stuart Shelf, Olympic Dam IOCG province including several geological challenges. Six metres of cobble conglomerate at the top of the hole are underlain by about 400 metres of Adelaidean shale, sandstone and minor carbonate which include the Tregolana Shale, Yerelina Subgroup and Tapley Hill Formation. The Neoproterozoic Beda Basalt, which has physical characteristics similar to fresh ‘basement’ rocks, underlies these units.
