Explore the dark side. When a quarry wants to optimize, it''s easy to concentrate on obvious value-creating events, such as crushing chamber performance. But these only account for about 5% of the entire quarry process. The remaining 95% of activities do not create value – minimizing them gives you excellent potential to boost profitability.

The required internal rate of return (IRR) for the mine/quarry operations is 20%pa. The value is determined using DCF. The use of DCF is justified in the case of mines and quarries because of their short life and the uneven and complex nature of the future income, returns and costs. The residual value is the NPV and equal to the land value.
