Rare earth drilling targets: Kriging variance at 40% — Drill or Delay?

A 40% relative kriging variance signals high estimation uncertainty at rare earth drilling targets. Learn when to drill now or when infill will not cheaply fix flaws.

Abstract

A 40% relative kriging variance signals high estimation uncertainty at rare earth drilling targets. Learn when to drill now or when infill will not cheaply fix flaws.
