Sector
applications
The same calibrated tool fleet and the same DEPTHS workflow, scoped around the question each sector asks: where is the ore, will the slope stand, where will the water come from, what is under the foundation.
Surface mining
Open pits and grade control
In surface mining, borehole logging delivers resource definition, lithological correlation, pit-slope structure, geotechnical domains, groundwater inflow, dewatering design and environmental baselines from the same holes the exploration and grade control programme is already drilling.
- Resource definition and lithological correlation
- Pit-slope structure and geotechnical domains
- Groundwater inflow and dewatering
- Environmental baselines for the licence
- Grade control from predictive assay
- Positioned holes for the block model

Underground mining
Shafts, development and cover holes
Underground, logging answers the questions that cannot wait for core: shaft and raise-bore investigations, development sterilisation, structural hazards ahead of the face, ground-support inputs, cover-hole water and gas risks, and directional control of long holes.
- Shaft and raise-bore pilot hole investigation
- Development sterilisation and reef imaging
- Structural hazards and ground-support inputs
- Cover-hole water and methane fissure detection
- Directional control and wedging QA
- Hazardous-hole deployment
Tunnels & dams
Ahead of the face, under the wall
For tunnels, logging finds faults, weak zones, cavities and groundwater ahead of excavation. For dams, it provides the rock mass, permeability and seepage inputs that foundation and rehabilitation design depend on, from investigation holes that would otherwise yield only core.
- Faults, weak zones and cavities ahead of tunnelling
- Groundwater and inflow prediction
- Rock mass classification for support design
- Permeability and seepage for dam foundations
- Plunge pool and abutment characterisation
- Radar imaging beyond the borehole
Roads & bridges
Continuous ground properties for linear infrastructure
Road and bridge investigations get continuous ground-property information for cuttings, abutments, piers, deep foundations, slope stability and material variability, so that design assumptions rest on measured properties along the whole hole rather than on a handful of samples.
- Cuttings and slope stability
- Abutments, piers and deep foundations
- Material variability along the alignment
- Dynamic elastic properties from sonic and density
- Fracture orientation and rock mass quality
- Groundwater for drainage design
Water & environment
Aquifers, monitoring wells and contaminant pathways
Water and environmental projects use logging for aquifer characterisation, monitoring-well condition, groundwater quality, contaminant pathways, and tailings and hazardous-storage monitoring, with calibrated, repeatable datasets that stand up in licence applications and audits.
- Aquifer characterisation and wellfield design
- Monitoring-well condition and integrity
- Groundwater quality profiling
- Contaminant pathway identification
- Tailings and hazardous-storage monitoring
- Baseline and repeat surveys on the same footing
Energy & industrial
Reservoirs, geothermal and critical infrastructure
Energy and industrial clients use logging for geothermal and reservoir characterisation, groundwater interaction, solution mining, in-situ adsorbed gas in coal and helium plays, CO₂ storage reservoirs, and subsurface risk around critical infrastructure.
- Geothermal and reservoir characterisation
- CCUS reservoir porosity and permeability
- Solution mining and lithium brines
- Adsorbed gas in coal and helium deposits
- Groundwater interaction with infrastructure
- Subsurface risk around storage and plant
