DMT Services

Comprehensive consultancy and operational support throughout all phases of mineral exploration

We offer comprehensive geological and mineralogical exploration services and support projects from the early stages of target identification right through to the robust estimation of mineral resources and reserves.

Our aim is to help our clients gain a precise understanding of the quantity, quality and distribution of their ore bodies and potential mineralisation, enabling them to make confident decisions at every stage of a mining project’s life cycle. With decades of global experience and a strong track record across all types of deposits, we combine technical excellence with practical, bespoke solutions that lead to successful exploration and development outcomes.

Mineral exploration

  • Target Area Assessment and Exploration Management
    : Identification of high-potential target areas, as well as the planning and management of efficient exploration programmes, supported by state-of-the-art multi-sensor core analysis (ANCORELOG) for rapid and high-quality geological data acquisition.
  • Geological mapping and structural interpretation
    : Recording and interpretation of geological structures to support exploration and deposit evaluation.
  • Drilling supervision, sampling & quality assurance
    Professional supervision of exploration and sampling operations, including QA/QC checks to ensure data quality and compliance with international standards.
  • Remote sensing and satellite-based exploration
    Use of airborne surveys as well as ASTER and Sentinel data to identify and prioritise exploration targets. For advanced projects, the results can be further verified and refined in a targeted manner through geophysical surveys, such as 2D and 3D seismic surveys.

Geological Modelling & Resource Estimation

  • Data Review & Validation / QA/QC
    Comprehensive data validation, QA/QC assessments and interpretation of exploration and production datasets.
  • Geostatistical Analysis
    Assessment of grade continuity, variability and uncertainty.
  • 3D geological modelling
    : Precise modelling of ore bodies, geological domains and structural features based on drilling data using modern modelling software
  • Creation of block models and mineral grade
    estimation Development of reliable block models and grade estimates as a basis for mineral resource reporting.

Reporting, compliance

  • International reporting standards
    Our estimates comply with leading international standards, including JORC, NI 43-101, PERC and other CRIRSCO-compliant standards.
  • Competent/qualified persons
    Recognised experts ensure compliance with regulations and credibility for investors and stakeholders.

Software and digital workflows

  • Leapfrog for implicit geological modelling
  • Datamine, Surpac and equivalent tools for block modelling and resource estimation
  • Geostatistical software for data analysis and uncertainty assessment

Our interoperable digital workflows ensure full traceability, verifiability and seamless integration with mine planning systems.

What you should know

Frequently Asked Questions on Deposit Exploration and Resource Estimation

DMT offers comprehensive support, ranging from the identification of targets at an early stage, through geological mapping, the monitoring of drilling and geophysical surveys, to the full assessment of mineral resources and reserves.

Accurate estimates of resources and reserves form the basis for project evaluation, mine planning, investment decisions and regulatory reporting. They reduce uncertainty and ensure that technical and economic assumptions are realistic.

All estimates comply with internationally recognised codes, including JORC, NI 43-101, PERC and other CRIRSCO-compliant standards. The work is carried out by competent/qualified persons.

We use industry-leading platforms such as Leapfrog, Datamine, Surpac and advanced geostatistical tools to ensure accurate modelling, traceability and seamless integration with mine planning systems.

Our experience covers ferrous metals, base metals and precious metals, coal and energy resources, industrial minerals, bulk materials and heavy mineral sands.

We provide transparent, justifiable models and estimates, minimise technical and financial risks, support regulatory compliance and deliver clear insights that underpin strategic and operational decisions.

Yes – we offer flexible collaboration models, ranging from advisory support to full integration into your exploration or resource geology team.
