Heavy Iron Ore Haul Corridor Audit
Engineering verification for a 120km heavy haul road designed for 100-ton rear dump ore trucks.
Selected Engineering & Mining Case Studies
Detailed technical overviews showcasing complex field problems, executed methodologies, and quantified results.
450M Metric Ton Bauxite Resource Verification
DMS Technical Consultancy managed drilling oversight, geological logging, and geostatistical block modeling for an international mining conglomerate operating in West Africa.
The Challenge
Complex lateritic ore cap geometry with variable silica contamination requiring high-density drilling QA/QC to secure international project funding.
Our Methodology
Deployed 4 diamond drill rigs, established duplicate core sample protocols, and constructed Ordinary Kriging block models using Leapfrog & Datamine.
Quantified Result
Successfully filed JORC Competent Persons Report, unlocking $320M in Tier-1 institutional debt finance for mine development.
Tailings Storage Facility (TSF) Structural Overhaul
Comprehensive stability evaluation and pore-water pressure depressurization engineering for an active upstream-raised tailings dam under extreme monsoon conditions.
The Challenge
Rising phreatic surface level inside tailings embankment posing seismic liquefaction risks during torrential rainy seasons.
Our Methodology
Installed vibrating wire piezometers, engineered downstream buttress fill, and implemented automated satellite InSAR displacement monitoring.
Quantified Result
Achieved full compliance with GISTM international tailings safety standards and increased recycled process water by 40%.
Industrial Gold Mine Dewatering & Wall Stabilization
Engineering a 14-borehole perimeter dewatering system to dry out high-wall slopes in a deep open-pit gold extraction operation.
The Challenge
High groundwater ingress causing bench slumping, equipment downtime, and elevated blasting explosive costs.
Our Methodology
Designed 3D MODFLOW hydrogeological grid, drilled perimeter deep wells, and routed discharge to community water treatment plant.
Quantified Result
Stabilized pit walls allowing steeper bench angles (+4°), reducing waste stripping volume by 1.2M bank cubic meters.
