Recoverable Resource Estimation by nonlinear geostatistics – Module 3: Simulations | Training course
Be at the forefront of mining geostatistics and learn how to estimate recoverable resources and assess the risks of your mining project using uniform conditioning, multiple indicator kriging, conditional expectation and geostatistical simulation.
Objectives
This course provides a solid foundation in geostatistical methods for recoverable resource estimation. The skills you will develop will assist you in:
– Estimating long-term resources,
– Estimating grade-tonnage curves during exploration.
It comprises three modules that can be taken separately:
- Module 1 dives into the importance of nonlinear techniques in generating unbiased grade-tonnage curves, especially in sparse sampling conditions. You will gain a deep understanding of Uniform Conditioning (UC) and confidently apply it to compute grade, tonnage, and metal quantities across various cut-offs.
- Module 2 explores Multiple Indicator Kriging and Conditional Expectation, helping you master when and how to apply each technique effectively.
- Module 3 introduces two powerful conditional simulation techniques for continuous variables like grades. You’ll also learn how to post-process results to generate accurate grade-tonnage curves.
Course content
- Introduction
– Understand the fundamentals of recoverable resource estimation and its critical role in resource modeling and mine planning. - Simulations
– Master simulation general 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.
Outlines
- Balanced learning approach: The course combines theory with practical applications, ensuring concepts are understood and applied effectively.
- Hands-on software training: Engage in computer-based exercises using Isatis.neo software, reinforcing learning through real-world data scenarios.
- Personalized feedback: Receive individualized guidance and feedback from experienced trainers during online sessions to support your learning journey.
- Comprehensive resources: Access detailed course materials, including documentation, journal files, and datasets, to reinforce learning and facilitate application post-training.
Who should attend
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.
Prerequisites
- Basic knowledge of linear geostatistics is recommended. The course Mineral Resource Estimation, covering the fundamental concepts of geostatistics for resource estimation, offers an ideal basis for this advanced course.
- A basic understanding of resource concepts such as grade, tonnage, and cut-off is beneficial.
- You can enhance your skills by participating in the two additional modules of this course: Module 1 focuses on Uniform Conditioning, while Module 2 focuses on Multiple Indicator Kriging, the two modules aiming at calculating metal and tonnage quantities.
