In this week's Fresh Thinking by Optiro podcast, Ian Glacken our Director of Geology, and Paul Blackney our Principal Consultant Geology discuss declustering and where to use it.
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 industry?
The podcast at a glance:
0:51 What is declustering and why is mining data clustered?
1:41 What are the implications of not declustering?
2:03 When is declustering useful?
2:52 Do we need to apply declustering to ordinary kriging?
3:26 What are some of the normal methods used when declustering?
5:12 So not everyone uses declustering. Why do some practitioners disavow it?
6:10 Do you both agree on when to apply declustering?
7:22 Are there any circumstances when its mandatory to decluster?
9:12 Where should people go to learn more?
Fresh Thinking from the World of Mining is a free podcast series from Optiro. In Part 1 of this two-part Politics and Ideology of Resource Estimation series, Optiro's Director of Geology Ian Glacken discusses the history and common practices of resource estimation.
