Seth Bullock, the owner of Bullock Gold Mining, is evaluating a new gold mine in South Dakota. Dan Dority, the company's geologist, has just finished his analysis of the mine site. He has estimated that the mine would be productive for eight years, after the gold would be completely mined. Dan has taken an estimated of the gold deposits to Alma Garrett, the company's 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 estimated provided by Dan to determine the revenues that could be expected from the mine. She also has projected the expenses of opening the mine and the annual operating expenses. If the company ope s the mine, it will cost $625 million today, and it will ha e 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 if its gold mines.
