  • 4 years’ experience working as a geologist across various opencut and underground mining projects in both coal and hardrock
  • Extensive field experience in coal exploration in the bowen basin including permitting, managing and undertaking drill programs, collection and interpretation of results from geophysical data and boreholes

Geology consultancy work includes:

Petrographic examination with vol% count of minerals of quarry products (igneous, metamorphic and sedimentary rock and sands) for various construction applications through thin section evaluation using a polarizing microscope in accordance with international / Australian standards. Includes comments of suitability for construction uses as well as free silica and asbestiform content.

Determination of secondary mineral content (or soft, weak minerals) by detailed counting under a petrological microscropic and visual counts of unsound fragments in an aggregate sample by Austalian standards.

Analysis of frictional ignition potential of sediments in proposed underground coal mines using Ward’s classification.  Involves petrographic identification and categorisation of minerals into grouping largely based on hardness of minerals plotted onto a ternary diagram.
