Mineral resource estimation produces a model of deposits for extraction and is made up of various complex processes. In part two of this two-part series, Optiro's Director of Geology Ian Glacken discusses how the various methods used for estimation can be controversial and takes a look towards the future.   In this episode: 0:50 What is the issue and what are the differences between global estimation and local accuracy? 3:55 How do you know which approach is applicable to your situation? 5:05 Is

Mineral resource estimation produces a model of deposits for extraction and is made up of various complex processes. In part one of this two-part series, Optiro's Director of Geology Ian Glacken discusses the history and common practices of resource estimation.   In this episode: 0:42 What are the main estimation methods used in mineral estimation worldwide? 1:33 What is the origin of the term 'Kriging'? 2:40 There are multiple methods for resource estimation, but why don't we all use the same one

Reporting the right information to investors is critical. The three main codes around the world that govern resource estimation and reporting to the market all contain references to RPEEE, or Reasonable Prospects of Eventual Economic Extraction. Optiro's Director of Geology Ian Glacken explains why the principle is critical to reporting resources. In this episode: 0:48 What is RPEEE? 1:33 Why do we need to have RPEEE as part of all the reporting codes? 2:28 The codes are there to protect investors

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 produce a more accurate picture of what's in the ground. Optiro's Director of Geology Ian Glacken explains the method, when it is appropriate and what happens when it's not used correctly. In this episode: 0:44 What is a top cut? 1:10 Why should you use a top cut? 2:03 When and where should you apply a
