30 Seconds of Info – volume variance relationships

Today’s 30 Seconds of Info comes from Ian Glacken our Director of Geology.

The volume-variance relationship is the key to resource estimation: understanding the relationship between samples of a certain size and their variability, and how this variability changes at different volumes (supports), can explain many of the apparent problems in a resource estimate.  Using one scale of estimate when you need a smaller or a larger scale is still a very common mistake.
