The challenge of sampling gold - SAIMM

Reconciliation is a common activity carried out at most mining operations around the world and can be defined as a comparison between the grade reported by the plant and the grade predicted by models. Of course these values rarely match, due to the different variables involved. The mine/mill reconciliation problem often has multiple causes.
