EP 157 | Part 4 of 7: Localised Conditional Simulation

In this episode of Fresh Thinking by Snowden Optiro, Ian Glacken and Susan Havlin explore localised conditional simulation (LCS) and its role in modern resource estimation workflows.

Building on earlier discussions around estimation methods, recoverable resources, and conditional simulation, this episode brings everything together to explain how LCS converts multiple simulation realisations into a single, practical block model—while preserving realistic grade variability.

Key topics include:

What localized conditional simulation is and why it matters
How localization transforms multiple realizations into a single model
The role of the E-type estimate in ranking and distribution
Differences between LCS and traditional ordinary kriging
How LCS supports recoverable resource estimation at the SMU scale
The origins of localization and its relationship to methods like uniform conditioning and MIK

6 - Declustering - what is the true grade?

Declustering is a critical technique to understand and use when estimating a resource. It helps you get a more accurate picture of the whole ore body, but why is it controversial in parts of the indus...

5 - Reconciliation

Getting reconciliation wrong can lead to dire consequences for miners. Mine reconciliation is the practice of comparing the tonnage and grade of material processed by the mill with the tonnage and gra...

1 - Top Cuts

When you're creating a resource estimate you need to be sure that you haven't relied on outlier samples. Top cutting (or capping) is a method you can use to reduce the impact of individual samples and...
