Geological Block Modeling Fundamentals for Mineralization

Accurate geological block models are essential for evaluating mineral deposits and guiding modern mining decisions. This text-based course provides a step-by-step guide to the fundamental concepts, workflows, and techniques behind block modeling mineralization. You will develop a practical understanding of how raw drillhole data is organized, validated, and transformed into structured 3D spatial models. What you will learn: Understand core geological terminology, spatial coordinate systems, and drillhole database structures; Perform data validation, compositing, and basic statistical analysis on sampling data; Define mineralized domains and wireframes using explicit and modern implicit concepts; Configure block model grids, cell sizes, and sub-blocking parameters for complex ore bodies; Apply foundational estimation methods, including inverse distance weighting and spatial kriging principles; Validate block model results using statistical checks and cross-section analysis. The course starts with essential terminology and data hygiene before moving through domaining, block setup, and spatial estimation techniques. This course is ideal for geologists, exploration staff, and mining students seeking a straightforward, beginner-friendly entry into geological resource modeling with no prerequisites needed.
