The JORC code does many things, but it doesn't prescribe how to consistently classify resources. Optiro's Director of Geology Ian Glacken explains some of the techniques available to ensure consistency in this fifth part of the mini-series on the JORC code.

In this episode:

1:22 When the JORC code is described as being principles-based, what does that mean?
3:16 So contrasting to other codes around the world, the JORC code is a good one, right?
4:33 Why can the JORC code be an issue for large companies?
5:39 What are some of the techniques for getting a more objective classification?
6:30 Is there a standard for objective resource classification? (90/15 rule)
11:16 Where can you get more information on this?
