The f2 factor usually relates received at mill measured by the mill tonnages, grades and metal content to delivered to mill production tonnages, grade and metal content. the f3 factor is f1215f2 and enables a comparison of a mines measured by mine ability to recover the tonnage, grade and metal content estimated in ore reserves.

Fluctuations in periodic reconciliations between the mine and the mill are an expected and common experience in mining and processing operations. these fluctuations are caused in part by errors in the estimates of tonnage and grade of the mined material as well as errors in the mills assessment of the material processed.
To combat this we focus more on the three month rolling mine to mill trends as the major trigger from a reconciliation perspective, with only major variances in the shorter daily to monthly measures seen as a cause of concern for example a major feed grade change not appearing in head grades over a week.
