Block Modelling And Resource Estimation Basics

Introduction to Block modelling

What you’ll learn
Geological Database Creation
Block modelling
Basic Resource Estimation
Requirements
Basic knowledge in mining
Basic knowledge in geology
Description
The block model is created using geostatistics and the geological data gathered through drilling of the prospective ore zone. The block model is essentially a set of specifically sized “blocks” in the shape of the mineralized orebody and it’s the standard in mining engieering for ressource estimation and reporting.This course is for resource geologists, geoscientists, and mining engineers who wants to get the basics of resource estimation and block modelling . The course starts with the creation of geological database using the drillhole data and how to create custom legends to visualize them in 3D, we take a look at some drillhole compositing basics , creating a blank block model setup it up for estimation. Since this course will cover only the basics the classical interpolation method will be used , which is inverse distance estimation to showcase the resource estimation process in an easy to follow way. This course will also explore a basic method of categorizing and reporting volumes and tonnages for resources. The software used in this course is Maptek Vulcan one of the top softwares used in the mining industry. Students are expected to have some basic mining engineering or geology knowledge. Questions related to the course subject are more than welcome and will be all answered.
