Mr John Elliston

John Elliston, Senior Research Associate and Consultant, has extensive experience in exploration and successful mineral development. During many years of active exploration and while directing major exploration, mining, and geophysical companies, new basic research into the origin, mode of transport, and concentration of ore minerals was initiated. Highly successful technical results achieved in the completion of recent research contracts now enables a realistic identification of the geological factors, which indicate potential economic mineralisation.
Research findings can be applied to assist decisions on area and prospect selection and the significance of partly delineated mineralisation.

  • Interpretation of geological data
  • Recognition of the significance of mineral indications
  • Assistance with decisions to continue or curtail drilling
  • Review of geological data and assessment of its adequacy
  • Assessment of ‘prospectivity’.

By arrangement, seminars or staff training courses on:-
The basic concepts of the formation of orebodies and the rocks from which they are derived.
