This case will require that you use Excel to calculate the Net Present Value, Internal Rate of Return, Modified Internal Rate of Return, and payback period of a project. You will need to provide answers to Steps 1 and 2 in the exercise using Excel to present your calculations. (Step 3 is not required.) You must use functions and formulas to perform all necessary calculations for Step 1.

Seth Bullock, the owner of Bullock Gold Mining, is evaluating a new gold mine in South Dakota. Dan Dority, the companys geologist, has just finished his analysis of the mine site. He has estimated that the mine would be productive for eight years, after which the gold would be completely mined. Dan has taken an estimate of the gold deposits to Alma Garrett, the companys financial officer. Alma has been asked by Seth to perform an analysis of the new mine and present her recommendation on whether the company should open the new mine.

Year	Cash Flow
0	$625,000,000
1	70,000,000
2	129,000,000
3	183,000,000
4	235,000,000
5	210,000,000
6	164,000,000
7	108,000,000
8	86,000,000
9	90,000,000

Alma has used the estimates provided by Dan to determine the revenues that could be expected from the mine. She also has projected the expense of opening the mine and the annual operating expenses. If the company opens the mine, it will cost $625 million today, and it will have a cash outflow of $90 million nine years from today in costs associated with closing the mine and reclaiming the area surrounding it. The expected cash flows each year from the mine are shown in the nearby table. Bullock Gold Mining has a 12 percent required return on all of its gold mines.

QUESTIONS

1. Construct a spreadsheet to calculate the payback period, internal rate of return, modified internal rate of return, and net present value of the proposed mine.

2. Based on your analysis, should the company open the mine?
