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?
4:57 Ordinary Kriging is probably the most popular technique. Why
is that?
6:56 Some techniques of resource estimation are controversial, like
inverse distance and polygonal methods. Why?
9:40 Now we have better technology than ever before. How does this
affect the methods used for resource estimation?
10:51 What is geostatistics and how has it influenced resource
estimation?
