Where this module sits

The “Recoverable Resource Estimation” course is delivered in four modules that you can take separately or in sequence.

Module 1 — Uniform Conditioning. Unbiased grade-tonnage curves from sparse drilling, localized to the SMU level.
Module 2 — Multiple Indicator Kriging and Conditional Expectation. Two nonlinear estimators and how to choose between them.
Module 3 — Simulations. Multiple realizations with Turning Bands, SGS, and direct block simulation, post-processed into grade-tonnage curves.
Module 4 — Advanced multivariate modeling. Trend, decorrelation by PCA, MAF and PPMT, imputation and ratio transforms.

Objectives

  • Generate multiple equally probable realizations of your grades with Turning Bands Simulation and Sequential Gaussian Simulation.
  • Choose between the two according to your deposit and your computing constraints.
  • Simulate directly at block scale to save time and disk space, and know when that shortcut holds.
  • Post-process a set of realizations into grade-tonnage curves, and read the spread across them as risk.

Target audience

Geologists, mining engineers, and professionals involved in feasibility studies or medium- to long-term planning who wish to deepen their theoretical and practical knowledge of mining geostatistics.

Content

 

Introduction

  • Understand the fundamentals of recoverable resource estimation and its critical role in resource modeling and mine planning.

Simulations

  • Master general simulation concepts. Learn the theory.
  • Model the Gaussian anamorphosis: Transform any distributions into Gaussian ones, a necessary step for nonlinear modeling.
  • Discover two widely used conditional simulation methods: Turning Bands Simulation (TBS) and Sequential Gaussian Simulation (SGS). Understand their theoretical foundations, practical applications, and where each method performs best.
  • Unlock the power of Direct Block Simulations: Bypass the traditional point-scale modeling approach with this efficient technique that generates block-scale simulations directly, saving valuable time and disk space without compromising accuracy.

Post-processing of simulation results

  • Produce robust grade-tonnage curves from simulations to support your resource evaluations.

What the course includes

  • Balanced learning approach. Theory paired with practical applications, so you understand and apply the concepts.
  • Hands-on software training. Computer exercises in Isatis.neo, on real datasets.
  • Personalized feedback. Individual guidance from experienced trainers throughout the online sessions.
  • Comprehensive resources. A temporary software license, course documentation, journal files, and datasets to keep and reuse after the course.
  • Certificate of completion issued at the end of the session.

Prerequisites

  • Basic knowledge of linear geostatistics is recommended. The Mineral Resource Estimation course, which covers the fundamental concepts of geostatistics for resource estimation, provides an ideal foundation for this advanced course.
  • A basic understanding of resource concepts such as gradetonnage, and cut-off is beneficial.
