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 there something about the culture of a country that determines the approach? 6:11 Are there any approaches that are less theoretically rigorous? 7:11 If some approaches aren't theoretically rigorous, how can you justify using them? 7:57 Why are some of the older techniques still used if there are better ones around? 8:50 What does the future hold for resource estmation? 11:00 Where can people get the paper you wrote on resource estimation?
