Settings and more Net Present Value-Unequal Lives Bunker Hill Mining Company has two competing proposals: a processing mill and an electric shovel. Both pieces of equipment have an initial investment. of $580,101. The net cash flows estimated for the two proposals are as follows: Net Cash Flow Year Processing Mill Electric Shovel 1 $233,000 $291,000 2 207,000 270,000 207,000 249,000 165,000 256,000 5 126,000 6 105.000 7 91,000 91,000 The estimated residual value of the processing mill at the end of Year 4 is $290,000.
