How this model works

Base = ore × grade × base recovery. Case = ore × grade × case recovery. Percent inputs are divided by 100. Incremental copper = case − base. Absolute change is measured in percentage points; relative change = incremental copper / base output.

Ore-equivalent change = incremental copper / (grade fraction × base recovery fraction). A zero base makes the relative and ore-equivalent comparisons undefined. A lower case recovery correctly returns a negative change. Costs, process kinetics and constraints are excluded; no metallurgical performance is validated.

Default example: 70,000 to 75,000 t Cu/year; +5,000 t, +5 percentage points and +7.1% relative output.
