This course is designed according to the latest regulations on public reporting of Mineral Resources. It aims at showing how state-of-the-art statistical and geostatistical techniques help answer the requirements of those regulations in an objective and reproducible manner. A particular emphasis is put on understanding sampling and estimation errors and related uncertainties, as well as how to assign levels of estimation confidence through the application of resource classification fundamentals. In addition to a solid introduction to mining geostatistics, this course provides a comprehensive overview of how modern techniques, such as conditional simulations, are currently applied in the industry.
