El Teniente is a panel caving mine. The nature of block caving is such that some dilution will occur as the stopes fail towards the draw points. At El teniente, there is more dilution in secondary stopes than primary sections (Susaeta, 2008). Dilution is quantified using CUI, which is an indicator of draw performance.
