After discovering a gold vein in the Colorado Mountains, CTC Mining Corporation must decide to go ahead and develop the deposit. The most cost effective method of mining gold is the sulfuric acid extraction, a process that could result in environmental damage. To begin mining CTC must spend $900,000 for new mining equipment and pay $165,000 for its installation. The mining operation will net the firm an estimated $350,000 per year and the vein is expected to last for five years. CTCs has no debt, preferred stock of $250,000 with annual dividends of $23,750. And $2.5 million in common stock with a cost of 15%. Assume that the cash flows occur at the end of each year.

c. Assuming environmental impacts are not considered, should the project be undertaken?

d. How should environmental effects be considered when evaluating this or any other project? How might these concepts affect the decision to invest?
