NPV embedded the concept of the time value of money, and therefore the construction period duration and the production life or Life of Mine (LoM) materially influence the NPV. Ergo, the scale of operations affects the construction period required, which in turn affects the quantum capital requirement or capital allocation.

The rate of production also affects the average grade that will be presented for processing. Typically, as the scale of production is increased, the cut-off grade is decreased to ensure that sufficient ore is available for mining. As the cut-off is decreased, so too is the average grade presented for processing.
