1. After discovering a new gold vein in the Colorado Mountains, CTC Mining Corp must decide whether to go ahead and develop the deposit. The most cost-effective method of mining gold is sulfuric acid extraction, a process that could result in environmental damage. Before proceeding with the extraction, CTC must spend $950,500 for new mining equipment and pay $185,500 for its installation. The gold mined will net the firm an estimated $335,000 each year for the 5-year life of the vein. CTCs cost of capital is 14%. For the purposes of this problem, assume that the cash inflows occur at the end of the year.
