I am curious about those Parrets rules but I can't find an article about it.
Mind to share?
The Pareto principle states that for many outcomes, roughly 80% of consequences come from 20% of causes (the "vital few"). Other names for this principle are the 80/20 rule, the law of the vital few, or the principle of factor sparsity.
https://en.wikipedia.org/wiki/Pareto_principleI am increasingly convinced that this rule applies in many areas of life.
and mining is no exception.
