RoXplorer® Trials

RoXplorer® coiled tubing drill rig on site during the Port Augusta field trial.

Successful field trials of the RoXplorer® coiled tubing drill rig at our Brukunga Drilling Research & Training Facility (South Australia), Port Augusta (South Australia) and Horsham (Victoria).

  • The Port Augusta trial demonstrated that the RoXplorer® system can successfully drill the consolidated Adelaidean cover of the Gawler Craton that overlies the Olympic Dam iron-oxide-copper-gold province.
  • The Horsham trial demonstrated that the system can successfully drill unconsolidated Murray Basin cover and underlying prospective basement.
    Both trials achieved rates of close to 100 metres per 12 hour shift. This has provided strong encouragement that the aim of $50/metre coiled tubing drilling can be achieved.
  • Recovering a geologically representative sample from RoXplorer® coiled tubing-drilled holes. Assays of the cuttings from the Port Augusta trial show a remarkable match to assays of diamond drill core from an adjacent hole, including across a one metre zone of low grade copper mineralisation at 400 metres depth.
  • Operating in temperatures from <0ºC (Horsham) to ~40ºC (Port Augusta).
  • Overcoming potential hole deviation problems and drilling straight and vertical holes in the trials.
