The accurate estimation and evaluation of the size and extent of an orebody is crucial to the success of a mineral exploration programme.

SGS combines the disciplines of geology, statistics and internationally accepted exploration practices to provide you with accurate and timely:

  • Orebody modelling
  • Resource estimation 
  • Ore reserve evaluation 
  • Geostatistical analysis

Independent, transparent reserve and resource estimation and evaluation services give SGS clients a competitive edge.  

At SGS, we ensure that your resource evaluations are accurate and completed in a fair and transparent manner. Our modelling, evaluation and estimation reports are completed by Qualified Persons (QP), ensuring that your results are compliant with National Instrument 43-101, JORC and related codes. 

Orebody Modelling

Orebody modelling is the geological basis of your mine planning. SGS has the geologists and engineers to help develop the modelling programme that is right for your project. These professionals have extensive experience developing models and evaluation procedures. They are skilled in the use SETCAD, POLYCAD, BLKCAD and other programmes to provide you with an accurate and complete model or evaluation of your ore reserves. 

A computer modelling project starts with a critical review of existing drill hole and surface or underground sample data, as well as plans and sections containing current geological interpretation.

Drill hole and/or sample databases are then created to provide the quantitative and qualitative information necessary to build a resource model. Once the model is complete, we can provide you with the following professional services:

  • Computer-based 3D orebody modelling
  • Sectional, longitudinal, 3D or multi-seam modelling
  • Variographic analysis of composite spatial continuity
  • Geostatistical analysis and block modelling

Information gained through orebody modelling is used for geostatistical analysis and block modelling. SGS block modelling estimates the tonnage and grade of ore within virtual blocks. For more information on geostatistical analysis and block modelling, go to:

  • Geostatistical Analysis and Block Modelling
  • Resource Estimation and Classification
  • Geometallurgy

Our professional staff use the data collected by orebody modelling to provide accurate estimations and classification of the resources available at your exploration site. For more information on our resource estimation and classification services, go to: Resource Estimation and Classification.
