EP 168 | When Geology Isn't Enough - Using Categorical Indicator Kriging to Model Diffuse Mineralisation

How do you model mineralisation when geological boundaries aren't clearly defined?

In this episode of Fresh Thinking by  @SnowdenOptiro  , Senior Consultant, Melanie Bulley is joined by Principal Consultant, Senzeni Matondi to explore how Categorical Indicator Kriging (CIK) can be used to model diffuse mineralisation more objectively and consistently.

The discussion covers:

• Why traditional wireframing can be challenging in diffuse deposits
• How probability-based domaining improves consistency
• The role of CIK in reducing subjectivity
• Building more robust and defensible resource models

Whether you're a resource geologist, geostatistician or mining professional, this episode provides practical insights into one of the industry's most powerful domaining techniques.
