| Summary: | Indonesia has small amount of coal reserve compared to other countries in the
world, but the demand of its coal is high, domestic and international, based on its
increasing coal production since 2007. The coal reserve itself, determined by
stripping ratio (SR) for the mine plan design from economic evaluation.
Many mine corporations, in this case coal mine, not aware of the uncertainties
especially economic uncertainty or sale price fluctuation. The corporation assume
that the sale price is constant throughout the life of the mine using discounted
cashflow method (DCF). Therefore, an advance method that can overcome this
uncertainty is needed, that method is real option valuation (ROV). This method can
determine the maximum value of SR for mine plan design based on every change in
sale price. The determination can be seen from option premium value from the
difference between DCF and ROV net present value.
Hopefully with ROV method can increase SR value for mine design plan, so that the
corporation has more coal reserve. This study can be a benchmark in determining
SR value for maximum coal reserve. |
