CFSG EMEA module C: Simulation of Continuous Variables for Uncertainty and Risk Analysis | Training course

The CFSG (Specialized Training Cycle in Geostatistics) is a high-level training program in mining geostatistics delivered by the Geostatistics Team from Mines Paris and Geovariances. This program aims to equip you with an in-depth understanding of geostatistics for mineral resource estimation, enabling you to create block models your company needs for confident mine planning when you return to work. Throughout the training, you will learn the theoretical aspects of the techniques presented and practice them through various exercises and a real-world project.

CFSG is intended for individuals whose time zone is aligned with Europe (France). It will be delivered online in 4 modules over 7 weeks during the first semester of 2026, starting in March.

This module is the third one of the CFSG series. At the end, you will be able to generate simulation realizations for quantified uncertainty analysis.

THEORY

• Introduction
  – Why resort to the Gaussian Model?
  – Transform from Raw to Gaussian quantities: Normal score and Anamorphosis
  – Gibbs Sampler and Zero-Effect management
• Simulation algorithms
  – Sequential Gaussian Simulations (SIS)
  – Turning Bands Simulations (TBS)
  – Direct Block Simulations for integrated support change
  – Stochastic Partial Differential Equations (SPDE) for handling local anisotropies
• Multivariate methods
  – Gaussian Mixture Model (GMM) for completing missing data while preserving statistical relationships
  – Projection Pursuit Multivariate Transform (PPMT) for decorrelating data with complex correlations to generate a coherent block model (correlations, ratios, chemical balance)

PRACTICE

Several exercises to learn how to run simulation variants and post-processing (probabilistic resource estimation, statistics, simulation reduction, grade-tonnage curves) using Isatis.neo Mining Edition.

Each module can be attended independently of each other. However, it is important to note that completion of Module A or having experience in geostatistics and Isatis.neo is a prerequisite for participation in any of these modules.

• Module A: Linear Geostatistics for Local Resource Estimation (mandatory)
  March 2-13 & March 23-April 3, 2026 – 20 days
  Master the fundamentals of spatial analysis, variography, and kriging. Learn to build reliable block models and quantify estimation precision.
• Module B: Nonlinear Geostatistics for Recoverable Resource Estimation (optional)
  April 13-17, 2026 – 5 days
  Explore nonlinear techniques to model grade-tonnage curves and estimate recoverable resources while accounting for cutoffs and mining selectivity.
• Module D: Simulation of Categorical Variables for Geology and Domain Modeling (optional)
  June 15-19, 2026 – 5 days
  Apply geostatistical simulation methods to model geological domains, lithology, and facies. Capture and represent spatial variability in categorical variables.

• Half of the training program is devoted to methodological presentations, and the other half to practical exercises to deepen understanding of the concepts.
  – Mines Paris professors give the methodological courses.
  – Geovariances consultants will drive the practical sessions from our French office.
  – For more convenience, these courses are recorded and made available to participants during the session and until one month after the end of the course.
• A typical training week would then be:
  – Monday, Tuesday, Wednesday, and Thursday: theoretical course (on a half-day) and hands-on practice with Isatis.neo Mining Edition (on the half-day following the theoretical course).
  – Friday: homework using Isatis.neo Mining Edition with compulsory rendering at the end of the day. Live corrections and comments from the teaching team. Validation of prior learning.
• CFSG is a full-time training. You are required to be present/connected for the duration of the sessions.
• CFSG is a certification training. The knowledge acquired in each module is validated through an examination. At the end of each module, you will get a training certificate that officially recognizes the full completion of the module.
• Course material and a temporary software license are provided.
• A minimum of 8 participants is required for a module to proceed.

The CFSG training program is intended for mining geologists and engineers who are willing to achieve a high level of proficiency in geostatistics.

Module A is ideal for newcomers to mining geostatistics. Modules B to D are designed for individuals who wish to delve into more advanced geostatistics.

The course is delivered in English and requires a good level of this language. A sound understanding of mathematics is also recommended.

As the course is online, a good-quality internet connection is required. We also appreciate that the participant’s camera is turned on for the session.​
