Our People

Mine Earth consist of a small group of highly qualified professionals with skills covering a range of disciplines. Our focus is to provide quality and specialised closure planning support to the resource industry.  
  • Shannon Mackenzie


    Director
    BAppSc(EnvMgt), BSc(Hons)(Geol)

    Since graduating in 1998, Shannon has worked in the mining industry in both operational roles and as a consultant. He has managed numerous multidisciplinary mine closure projects in Australia and overseas.

    Shannon has worked in Australia and Papua New Guinea in the field of mine closure, including project management of closure projects, closure cost estimation, stakeholder engagement, assessments of mine waste, landform design, closure options assessments, groundwater and surface water investigations and other technical studies.

    He applies his geological skills to assess the geochemical and physical properties of mine waste and develop effective recommendations for their management. Shannon's experience in this field enables effective design and implementation of programs to assess mine waste including geological interpretation and targeted sampling and testwork.

    Shannon has been instrumental in developing leading approaches to mine closure and since 2006 has presented papers at national and international conferences on mine closure.

    Apart from his experience in the field of mine closure, Shannon has worked as a mine geologist, exploration geologist, mining environmental advisor and contaminated sites advisor.

    Shannon's unique skills and experience contribute to effective closure outcomes.

  • Stacey Gregory


    Principal Consultant
    BSc(EnvSc), MSc(EnvBio)

    Stacey has worked in the mining industry since 1999 in both operational roles and as a consultant. She has widespread experience in rehabilitation planning and monitoring, development of closure objective and criteria, environmental impact assessments and baseline studies.

    Stacey has led numerous large scale and multi-disciplinary projects investigating mining environmental impacts and developing key performance indicators. She has designed targeted closure performance monitoring programs and has monitored rehabilitation at over 20 mine sites within Western Australia. Her focus is the compilation and analysis of data to ascertain the risks and requirements for closure. This has led to the development of acceptable closure objectives and criteria to support effective relinquishment targets for a number of mining projects.

    Stacey has presented papers at both national and international conferences, and has published a paper in Hydrobiologia the international journal of aquatic sciences. In 2005, Stacey received a research grant from the Minerals and Energy Research Institute of Western Australia and subsequently published a report titled “The classification of inland salt lakes in Western Australia”.

    Stacey joined Mine Earth as a Principal Consultant in 2010 and contributes a unique blend of project management and analytical skills that compliment successful mine closure planning.
