Description

This block modelling course will teach you to create an efficient block model and estimate the grade and tonnage of a mineral resource using one of the best software in the mining industry which is Micromine. This advanced course outlines the main steps needed to perform the estimation and provides background information where needed to explain the underlying statistical concepts.

This course begins by statistically describing the data (mean, median, histograms…), and then we move to the steps required to construct a block model like Drillhole compositing, blank model creation, and the classical Inverse Distance Weighted (IDW) interpolation for estimation. Lastly, we will classify the block model into Measured, Indicated, and Inferred categories based on the level of confidence in the assay data and how close the estimated block is to the assay data and then report on the ore grade and tonnage within each category.

Even though this course might look like it is for experienced geologists, mining engineers, or geoscientists, in general, it’s delivered in an easy-to-follow methodology where beginners can follow along too. Any questions related to the course subject, or the software used will be answered and more lectures will be added if needed.
