Presenter and Course Developer: Matt Mullins

Special introductory offer of only US$4,000 per person

Resource Estimation – a practical step-by-step guide from data to resource – coal specific

This 5-day course gives you a clear understanding of the resource estimation process from interpretation through to classification.
Each attendee will receive a FREE temporary Supervisor software licence.

Key topics covered in this course include:

  • How to create a robust resource estimate with industry-standard software and techniques
  • How to explore your data and combine geology and geostatistics to build more robust estimates
  • How to understand and follow reporting codes and practical guidelines for resource classification

The course covers the entire resource estimation process including:

  • Introduction – flow of tasks, key concepts
  • Data quality – QAQC, sampling, database
  • Domaining and data preparation – the how and why of boundaries, coding and compositing
  • Statistics – exploring and describing good and bad data sets, declustering and topcutting
  • Variography – understanding grade continuity, modelling variograms, moving from the variogram to the estimate
  • Estimation – understanding kriging, exploring MIK, inverse distance and 2D estimation.
  • Estimation of wash data – understanding and modelling the beneficiation process
  • Model validation – tools and techniques
  • Post-processing – understanding change of support and recoverable resources
  • Classification and reporting – understanding the Codes and types of reports
  • An introduction to Conditional Simulation for risk and uncertainty

Course outcomes – you will:

  • Understand what affects a good and a bad estimate
  • Appreciate the paramount value of data and how to ensure its highest quality
  • Understand and apply the principles of sampling and QAQC for quality assurance
  • Know how to turn a first-class geological model into correct zones for estimation
  • Learn how to validate zones and their boundaries against the data and geology
  • Understand the critical role of geological and grade continuity
  • Cover the key geostatistical methods of grade estimation and compare these with other approaches
  • Know what to do when you don’t have enough data
  • Understand the many ways to validate your work and which are the best
  • Appreciate the key criteria for resource classification.

This course has been designed for geologists and mining engineers involved with or about to become involved with resource estimation.

The course assumes a basic knowledge of geology, sampling, QAQC and statistical concepts but does not assume any geostatistical knowledge.
