A coal deposit can be mined more rapidly if a third dragline and conveyor system is added. The initial cost would be $1.5M. Annual revenues for each of the next 12 years would increase from $800K to $1200K, and then for the next 6 years, revenues would drop from $800K to $0. Thus, the mining is 50% faster, and the deposit is depleted 6 years earlier. The system will have no salvage value. What is the IRR of the investment? Graph the PW for interest rates of 0% to 30%?
