After discovering a new gold vein in the Kilimambogo Mountains, ABC Mining Corporation must decide whether to mine the deposit. The most cost-effective method of mining gold is sulfuric acid extraction, a process that results in environmental damage. To go ahead with the extraction, ABC must spend Shs.9, 000,000 for new mining equipment and pay Shs.1,650,000 for its installation.The gold mined will net the firm an estimated Shs.4, 000,000 each year over the 5-year life of the vein. ABCs cost of capital is 12%. For the purposes of this problem, assume that the cash inflows occur at the end of the year.
