22 - Recoverable resources (part 1)

Geologists need to make predictions about how much can be extracted from an ore body based on limited data. What can you do to confidently report on the likely tonnage and grade? In part one of this two-part series, Senior Geostatistician at Geovariances, David Barry, and Director of Geology at Optiro Ian Glacken discuss recoverable resources and how to apply uniform conditioning. In this episode: 1:25 What are recoverable resources? 2:34 What is the difference between recoverable and ordinary resources? 3:48 Is there a difference between recoverable resources and reserves? 4:46 What needs to happen to a recoverable resource to make it into a reserve? 7:00 What are the main techniques for recoverable resource estimation? 7:32 What is uniform conditioning? 11:16 What would a typical uniform conditioning workflow look like? 13:58 What are the key assumptions we have to make when performing uniform conditioning? 17:34 Does uniform conditioning work for underground mining? 18:26 Where can people find out more about uniform conditioning?
