Renfree Mines, Inc., owns the mining rights to a large tract of land in a mountainous area. The tract contains a mineral deposit that the company believes might be commercially attractive to mine and sell. An engineering and cost analysis has been made, and it is expected that the following cash flows would be associated with opening and operating a mine in the area:

Cost of equipment required	$	740,000
Annual net cash receipts	$	385,000*
Working capital required	$	265,000
Cost of road repairs in three years	$	74,000
Salvage value of equipment in five years	$	100,000
*Receipts from sales of ore, less out-of-pocket costs for salaries, utilities, insurance, and so forth. The mineral deposit would be exhausted after five years of mining. At that point, the working capital would be released for reinvestment elsewhere. The company
