Mining is an integrated operation that includes planning, mining (excavation), processing, and metallurgy where metals are extracted. A mining-plan of operation forecasts the amount of ore to be mined and/or metal to be produced at the beginning of a year. The model-mine-mill (M3) reconciliation is a set of activities carried out by mining operations in order to measure success and predict success of mine plan. Success in annual production of a mine depends on many factors such as a good mine plan based on a nearly robust resource/ reserve model, execution of mine-plan in the operation supported by reliable laboratory services and disciplined work-culture led by a competent workforce.
A model-mine-mill (M3) reconciliation process helps to gain knowledge on the actual (or, likely) reasons for achieving the planned production or, not. When properly implemented, a detailed model-mine-mill (M3) reconciliation process leads to finding out the areas for further improvements leading to substantial enhancements in productivity. A successful mining operation often conducts the reconciliation at regular time intervals.
