- Geological skills are used to interpret deposit geology and the geological factors that control rock stability (lithology, mineralogy, structure, alteration and weathering).
- A landform scale approach to stability assessment, rather than single point assessment and interpretation of sample results.
- Co-disposed rock types and their relative abundance are considered, rather than an assessment of individual rock types in isolation.
- Ability to predict the relative erosion / decomposition rates for various rock types and stability zones.
- Rapid, efficient and cost effective approach.
- Common laboratory methods of assessing the stability characteristics of waste rock are typically ineffective in determining as-dumped stability characteristics.
